		<summary type="html">&lt;p&gt;GreatWyrmGold: /* Explanation */ Randall Munroe has written particle physics comics before, but this is not one of them.&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1422&lt;br /&gt;
| date      = September 17, 2014&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Beret Guy|Beret Guy's]] phone is about to &amp;quot;die&amp;quot;. [[Cueball]] assumes this just means that the battery is running out and it needs to be recharged, but the phone in question appears to &amp;quot;die&amp;quot; in a way analogous to the {{w|Stellar_evolution|life and death}} of a star: expending its fuel while heating up and expanding before ultimately losing its outer layers and becoming a white dwarf or similar &amp;quot;lesser&amp;quot; star. The technology of mobile phones can be seen as doing things analogous to this on a large scale, especially for people who used landlines before mobile phones became common. This is something phones usually don't literally do, although there is a failure mode where the battery continues to expand, which can burst the rest of the phone apart.&lt;br /&gt;
&lt;br /&gt;
In part because stars are really hot,{{Citation needed}} stars constantly undergo fusion reactions. The pressure generated by these reactions counteracts gravity, preventing it from collapsing the star during its main lifespan. As the hydrogen mostly fuses into helium in the core, the core gradually becomes more dense and the region of fusion gradually moves away from the center. Then, the star grows in size, reaching the stage of a {{w|red giant}}. When most of the &amp;quot;fuel&amp;quot; for fusion has been consumed, gravity will collapse the star into a {{w|white dwarf}} while the outer layers are shed. For stars much more massive than the Sun, there will be a {{w|supernova}} explosion caused by a violent collapse, which is {{what if|73|very powerful}} (and leaves behind a {{w|neutron star}} or a {{w|black hole}}, depending on how much mass is left after the supernova). Stars with more hydrogen fuel tend to burn brighter and faster. Beret Guy's refusal of a charger is probably a reference to this.&lt;br /&gt;
&lt;br /&gt;
Both a supernova explosion and the collapse of red giants into white dwarfs shed their outer layers, which is referenced in the title text. Once extra mass is added to the dying star, analogous to &amp;quot;charging&amp;quot;, the process only accelerates. (Randall also explains this in {{what if|14|Short Answer Section}}.) The phone seems to have a certain mass because [[Beret Guy]] expects it to go (super)nova. Charging the phone may lead to a {{w|Nova|type 1a nova}}.&lt;br /&gt;
&lt;br /&gt;
The comic also plays on the release of two new {{w|IPhone|iPhone models}} with {{w|IPhone 6|bigger}} screens, planned for 2 days after the release of the comic.&lt;br /&gt;
&lt;br /&gt;
The comic could be also explained by the characteristics of Li-ion batteries, which are used in most cellphones. At the end of their useful life, these batteries may [https://www.allmobilematters.com/bloated-batteries-and-the-damage-they-cause/ grow] [https://web.archive.org/web/20120909030631/https://barnson.org/node/1842 a bit]. In case of severe physical or thermal damage or multiple electrical failures, this type of battery can indeed overheat, leading to a {{w|thermal runaway}} reaction inside. That would result in the battery [http://www.dailymail.co.uk/sciencetech/article-4010386/Incredible-X-rays-lithium-ion-batteries-explode-Gas-pillows-cause-cells-swell-catch-fire.html growing and eventually exploding]. Connecting a charger to a battery failing in this manner would [http://batteryuniversity.com/learn/article/safety_concerns_with_li_ion probably make the process faster].&lt;br /&gt;
&lt;br /&gt;
The title text implies that after Beret Guy's iPhone goes (super)nova, it will become either a &amp;quot;slowly fading&amp;quot; Palm Pilot, a calculator, or a two way pager: this would be the cellphone equivalent of a {{w|white dwarf}} (evidenced by the faint and slowly fading glow), {{w|neutron star}}, or {{w|black hole}} (evidence: black holes emit &amp;quot;information&amp;quot; in the form of {{w|Hawking radiation}} and have at one time been suspected to be half of a two-way portal through spacetime, along with a &amp;quot;{{w|white hole}}&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball stands on the left while Beret Guy walks in from the right, carrying a smartphone.]&lt;br /&gt;
:Beret Guy: My phone's about to die.&lt;br /&gt;
&lt;br /&gt;
:[The phone is now subtly larger.]&lt;br /&gt;
:Cueball: Where'd you get a big iPhone? I didn't think they were out yet.&lt;br /&gt;
:Beret Guy: It's my regular one. It's just dying.&lt;br /&gt;
&lt;br /&gt;
:[The phone increases in size again. Beret Guy now holds it in both hands.]&lt;br /&gt;
:Beret Guy: As it consumes its battery, it heats up and expands.&lt;br /&gt;
:Beret Guy: Soon it will swell to enormous size, engulfing us both.&lt;br /&gt;
&lt;br /&gt;
:[The phone is now in the size of Beret Guy's torso; he is clutching it to himself. Cueball is pointing off-panel.]&lt;br /&gt;
:Beret Guy: Then it will collapse in a violent explosion!&lt;br /&gt;
:Cueball: ...do you want to borrow my charger?&lt;br /&gt;
:Beret Guy: That would only make it run out ''faster!''&lt;br /&gt;

[[First]] post!!!!!!!!!!!!!!!!!!!!!!!!!!! Anyway, the explanation looks like a train wreck, and I'm not sure if a rearranging it into a table or just adding bullet points to everything is better.

: Thank you so much for using a list instead of a table! I read this on an Android phone, and tables on this site are hard to read.  The first column comes out with really small text, and since the cell vertical alignment is not 'top' I have to scroll down to find what the row is about, then scroll back up to try to find the rest of the row.

Regarding &amp;quot;Factor a prime&amp;quot;: Factoring a prime is easy: The prime itself is the only factor, so it's sufficient to use [https://en.wikipedia.org/wiki/AKS_primality_test AKS] or whatever to check that. Public-key encryption relies on how hard it is to factor the product of two primes, which is a much harder problem. Maybe this is a typo in the comic? {{unsigned|Comment Police}}&lt;br /&gt;
: I don't think it is a typo. It's exactly the type of &amp;quot;inside-joke&amp;quot; I would expect from XKCD. :) --[[Special:Contributions/162.158.134.214|162.158.134.214]] 10:09, 19 February 2018 (UTC)&lt;br /&gt;
:: AFAIK, there aren't any primality tests known to run in O(log n). For instance, AKS runs in O(log n ^ 7.5). So for numpy to actually achieve factoring as stated would require assuming the input is prime and just returning (1,n). --[[User:Quantum7|Quantum7]] ([[User talk:Quantum7|talk]]) 12:45, 19 February 2018 (UTC)&lt;br /&gt;
:::Doesn't testing for primality (just) require a list of all primes up to sqrt(n)? So the best possible time is sqrt(however fast you can calculate primes up to a number). That time can at most be square (divide every number by every other number below it), so a primality test only needs O(n) time. Or do I understand something wrong?

: There are a bunch of things going on:&lt;br /&gt;
:  * NumPy currently has no primality or factoring functions.  SymPy does.  We assume the hypothetical CVE happened because someone added it.&lt;br /&gt;
:  * Factoring a prime is a bit nonsensical.  We factor into primes or perform a primality test.  Perhaps a reference to the humorously mis-spoken Bill Gates quote: &amp;quot;The obvious mathematical breakthrough would be development of an easy way to factor large prime numbers.&amp;quot; -Bill Gates, The Road Ahead, pg. 265.  We know what he meant (and he likely does too) but it's technically just wrong.&lt;br /&gt;
:  * The best known factoring methods are sub-exponential, not polynomial as $O(\log n)$ indicates.  The current explanation test here is factually wrong (but gets the concept across) -- it isn't $O(2^n)$.&lt;br /&gt;
:  * Deterministic 64-bit primality testing is $O(\log^2 n)$ using BPSW or deterministic Miller-Rabin.  This worse than $O(\log n)$.&lt;br /&gt;
:  * Heuristic or probabilistic testing for larger inputs is also $O(\log^2 n)$.  The best deterministic method for larger inputs is ECPP at $O(\log^4 n)$, which is faster than AKS's $O(\log^6 n)$ in addition to much smaller constants.&lt;br /&gt;
: Ignoring or being amused at the &amp;quot;factoring primes&amp;quot; comment, we see the complexity is actually in the correct form (most internet forum contributers mix up &amp;quot;n&amp;quot; vs. &amp;quot;size of n&amp;quot;, for example).  If it were factoring composites, then $O(log^k n)$ for any constant 'k' would be funny as it says nobody noticed they added a polynomial time factoring algorithm.  If it is primality testing then it's funny as-is since this is faster than any known method (basically saying you could do a primality test on any size input with a constant number of multiplies).&lt;br /&gt;

I think the explanation of the one about injecting arbitrary text onto a page with the comments box is overthinking the joke.

:Isn't the joke really in the hilarious severity assessment?

Population: a single, very old kernel version on a rare, outdated architecture, in one timezone only - and WHICH timezone! UTC+14 means just a couple of islands in the Pacific (Tonga, Kiribati...) - the probability of even one vulnerable system actually existing seems almost zero. Impact: the only possible consequence is switching from 12h to 24h (only in this direction)?

I think the article should start with an explanation of what is the CVE. From https://cve.mitre.org/&lt;br /&gt;
 &amp;quot;CVE® is a list of entries—each containing an identification number, a description, and at least one public reference—for publicly known cybersecurity vulnerabilities.&lt;br /&gt;

It's my first comment here, so I may be wrong. I see the &amp;quot;CRITICAL&amp;quot; as a &amp;quot;differential” joke exhibiting that the requirement standards may be very different from a constructor to another. In fact, it seems that the apple’s bugs described here (crash, fire, remote access granted) are the mosst critical ones. The only two concerning Linux are the one labeled as critical and the one about bribery. I don’t know what to think about the almost complete absence of windows though. Feriaman.&lt;br /&gt;

&amp;quot;Flash was discontinued&amp;quot;, really? Someone should tell Flash. And Facebook. I'm STILL experiencing issues on Facebook over their sloppy Flash programming interfering with my ability to watch Facebook videos (extra irritating as I'm sure my newly built computer is more powerful and capable than the computers owned by anyone I know, and certainly any phone or tablet, which don't experience these problems). And my last Flash update was a couple of weeks ago - seeing as this bug likes to include telling me I need to upgrade my Flash, even if I did so that day and Flash assures me I'm up date.

:Flash hasn't been discontinued, but I think one could call it deprecated.  Adobe announced that they will [https://theblog.adobe.com/adobe-flash-update/ stop updating and distributing Flash in 2020] so it will be &amp;quot;discontinued&amp;quot; in 2-3 years.  Which means that if you're a web site owner, now's the time to migrate any Flash content to another platform (like HTML5/JavaScript).  Additionally, most modern browsers make a point of disabling flash by default, forcing you to enable it on a per-site basis.

 Timing Attack to exploit a race condition in garbage collection refers to Meltdown and Spectre CPU flaws that can be exploited in cloud server like the ones in Wikipedia.&lt;br /&gt;
I don't think this is correct. Garbage collection is a technique of freeing up memory no longer used by a program, completely unrelated to speculative execution and the Spectre/Meltdown exploits... [[User:Jaalenja|Jaalenja]] ([[User talk:Jaalenja|talk]]) 07:34, 20 February 2018 (UTC)&lt;br /&gt;

 Apple products execute any code printed over a photo of a dog with a saddle and a baby riding it.&lt;br /&gt;
 ... This &amp;quot;bug&amp;quot; would not only require the device to figure out specifically what the photo contains image-wise, something that's REALLY HARD for computers to do reliably, it would also require OCR (Optical Character Recognition) type code to convert the text superimposed on the photo into executable code. In other words, it's hard to believe in 2018 that such a bug could exist. Maybe in the future when such things are more routine...? ...&lt;br /&gt;
The funny thing is that I don't think it's beyond the realm of plausibility.  Given the fact that modern operating systems try to index as much as possible, for faster searches, it seems logical that some OS (if not now, then in the future) would try to run OCR against every image and video in order to index whatever text it finds (much like how YouTube auto-generates captions by running speech-recognition over the entire soundtrack).  Ditto for more generic image recognition to identify and index the picture content.  A system that does this could easily end up with a bug (or back door) where certain kinds of image content result in an attempt to execute its OCR results as code.

Does anyone think the 'I before E' could be a stab at Apple, in reference to Internet Explorer?{{unsigned|Comment Police}}&lt;br /&gt;
&lt;br /&gt;
While it is true that part of the plot of the movie &amp;quot;Air Bud&amp;quot; was that there was nothing in the rules to prevent a dog joining a basketball team, I suspect that the recent attempt to run a dog as candidate for governor of Kansas was more on Randal's mind than a 20+ year old movie that (at most) a few million people saw when it was released.[[Special:Contributions/162.158.78.16|162.158.78.16]] 05:27, 22 February 2018 (UTC)&lt;br /&gt;
: Actually, I find AirBud has become more of a thing to reference than a movie to watch. I believe the idea has been recycled a few times (a dog playing football, I think a dog playing baseball), yet it's AirBud, the original, that's always getting referenced (okay, &amp;quot;always&amp;quot; is an overstatement, but still). At the very least I know Randall has referenced it a few times, sometimes by name, enough times that I'd say it's safe to say AirBud is on his list of favourite references. If anything, this dog governor sounds obscure enough that he may not have heard about it, making the AirBud reference more likely, though being wacky politics I wouldn't be surprised if he's well aware, either. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:49, 23 February 2018 (UTC)&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is a map of the United States, purporting to explain some of the most significant elements of the landscape in each region. For each area it names one major geological or human mechanism (plate tectonics, erosion, farming, etc.) which it claims is responsible for the majority of interesting formations and features.&lt;br /&gt;
&lt;br /&gt;
Many of these causes are summarized in a single word answer, which is overly-simplistic when trying to explain a complex landscape. A few phrases are longer, but still don't actually explain much, and some areas are just labeled &amp;quot;geology&amp;quot;, which while lacking in explanatory power, is often solely responsible for some of the most striking landscape features. &amp;quot;Geology&amp;quot; is in fact poor label here, since almost all of the other causes (volcanos, glacial erosion, plate tectonics, etc.) are all elements of geology.  Randall appears to default to &amp;quot;geology&amp;quot; as the cause in areas where the landscape is largely made of metamorphic or igneous rocks (mountainous areas) instead of some alteration of base rock features via volcanos, earthquakes, etc.  However, the actual landscapes in these areas do have specific causes, as shown by the fact that the Appalachians are labeled as &amp;quot;continents colliding&amp;quot; not &amp;quot;geology&amp;quot;.  Similar more detailed explanations could have been given for other areas, for instance {{w|Laramide_orogeny|&amp;quot;one continent sliding under another&amp;quot;}} for the Rocky Mountains compared to &amp;quot;continents colliding&amp;quot; for the Appalachians.&lt;br /&gt;
&lt;br /&gt;
The title text plays off the fact that a large part of geology is concerned with activity in the mantle, so explaining some geologic feature by saying &amp;quot;there's speculation that it's due to a mantle hotspot&amp;quot; does not give much information. The suggestion is that this would let a distracted geologist buy time while responding to a missed question. Many of Earth's seemingly out-of-place features (e.g., {{w|Hawaii hotspot}}, {{w|Iceland}}, the {{w|Snake River Plain}} in Idaho, etc.) form from such mantle hotspots, so it's an easy go-to explanation for many of the geological features people are often most curious about.&lt;br /&gt;
&lt;br /&gt;
This map with subdivisions follows up on a number of prior (non-[[:Category:Bad Map Projections|cursed]]) maps representing (supposed) geographical splits of some conversational outcome or other, such as [[1407: Worst Hurricane]] and [[2108: Carbonated Beverage Language Map]].&lt;br /&gt;
&lt;br /&gt;
===Table of regions===&lt;br /&gt;
{| class=&amp;quot;wikitable sortable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! Location&lt;br /&gt;
! Description&lt;br /&gt;
! Explanation&lt;br /&gt;
|-&lt;br /&gt;
| Adirondack Mountains&lt;br /&gt;
| ???&lt;br /&gt;
| The Adirondack Mountains are made of billion-year-old rock but were uplifted relatively recently, within the last 5–10 million years. They are still rising today despite being far from any plate boundary, forming a dome with no clear tectonic cause. Thus this region is marked with a &amp;quot;???&amp;quot;. A possible explanation for this behavior was suggested recently in [[3141: Mantle Model]]. &lt;br /&gt;
|-&lt;br /&gt;
| Most of northern conterminous U.S.&lt;br /&gt;
| glaciers&lt;br /&gt;
| During the {{w|Last Glacial Period}}, this area was covered by {{w|Laurentide Ice Sheet|an ice sheet}} that left its marks on the landscape, in the form of {{w|moraines}}, {{w|eskers}}, {{w|glacial erratics}}, etc. This is most notable in Wisconsin where bluffs were formed due to the glacier movement.&lt;br /&gt;
|-&lt;br /&gt;
| Appalachian Mountains&lt;br /&gt;
| continents colliding&lt;br /&gt;
| {{w|Geology of the Appalachians|The Appalachian Mountains formed roughly 480 to 300 million years ago}} through a series of continent-continent collisions, culminating in the assembly of the supercontinent Pangaea. The primary collision involved ancestral North America (Laurentia) crashing into Gondwana (Africa/South America), resulting in a Himalayan-scale mountain range.&lt;br /&gt;
|-&lt;br /&gt;
| Mississippi and Ohio River Basins&lt;br /&gt;
| rivers&lt;br /&gt;
| The {{w|Mississippi River}}'s geology has a complex, 70 million year history involving massive sediment deposition, glacial activity, and tectonic shifting. Formed mostly by melting glaciers ~12,000 years ago, it drains a vast, shifting basin, depositing millions of tons of sediment in a massive delta and creating a vast, shifting alluvial plain. The {{w|Ohio_River#Geology|Ohio River's geology}} is similar.&lt;br /&gt;
|-&lt;br /&gt;
| Southeastern U.S.&lt;br /&gt;
| farming&lt;br /&gt;
| Landscape changes from {{w|cotton production in the United States}}, due to the presence of the {{w|Black Belt (geological formation)|Black Belt}}.  From the perspective of landscape features, it would be more accurate to say that they were caused by &amp;quot;erosion&amp;quot; not &amp;quot;farming&amp;quot;.  The Atlantic Coastal Plain is made up of sediments and sedimentary rock eroded from the Appalachian Mountains over millions of years.  The relatively flat landscape and loose fertile soils make farming both easy and productive respectively.  Thus farming is a result of the landscape features, not a cause of them.&lt;br /&gt;
|-&lt;br /&gt;
| Southern Florida&lt;br /&gt;
| ongoing disputes between limestone and water&lt;br /&gt;
| Florida is a vast {{w|karst}} landscape formed by the dissolution of underground limestone and dolostone bedrock by acidic rainwater, resulting in a terrain characterized by sinkholes, springs, caverns, and disappearing streams. This soluble bedrock, formed from ancient marine deposits, covers much of the state, directly connecting surface water to the Floridian aquifer system.&lt;br /&gt;
|-&lt;br /&gt;
| Southern Missouri / Northern Arkansas&lt;br /&gt;
| geology&lt;br /&gt;
| The {{w|Ozark Mountains}}, which are composed primarily of ancient limestone and {{w|dolomite}}, form a rugged landscape characterized by hills, caves, and springs. Prolonged erosion of these soluble rocks has produced extensive karst features, including sinkholes and underground rivers.&lt;br /&gt;
|-&lt;br /&gt;
| {{w|Great Plains}}&lt;br /&gt;
| farming&lt;br /&gt;
| The lack of other major events left the terrain relatively level; as with the Southeastern U.S./Atlantic Seaboard (see above), the cause of the landscape here is erosion of the Rocky Mountains, with the sediments carried by rivers towards the Mississippi basin and creating a flat, even landscape. Areas were historically shaped by either herds of bison or indigenous agriculture, both limiting the growth of forests. &amp;quot;Farming&amp;quot; is likely a reference to the more recent mix of large-scale crop farming (especially staples like wheat and corn) and herding (bison replaced by cattle). European plowing techniques unsuited for the dry plains ultimately resulted in the {{w|Dust Bowl}}, a period of intense erosion and dust storms which reshaped the landscape.&lt;br /&gt;
|-&lt;br /&gt;
| Central Idaho / Yellowstone&lt;br /&gt;
| a supervolcano&lt;br /&gt;
| The {{w|Snake River Plain}} is an area of high-elevation flat plain in the otherwise contiguous Rocky Mountains. It was formed by the movement of the continental plate over the {{w|Yellowstone Hotspot}}.&lt;br /&gt;
|-&lt;br /&gt;
| American West surrounding Idaho / Yellowstone&lt;br /&gt;
| geology&lt;br /&gt;
| [[3162: Heart Mountain]]&lt;br /&gt;
|-&lt;br /&gt;
| Immediately off of West coast up to the Four Corners&lt;br /&gt;
| volcanoes&lt;br /&gt;
| A combination of various {{w|volcanic field}}s of different origins, including {{w|Cascade Volcanoes}} in the Pacific Northwest, {{w|Albuquerque volcanic field}} in New Mexico, {{w|San Francisco volcanic field}} in Arizona, and {{w|San Juan volcanic field}} in Colorado.&lt;br /&gt;
|-&lt;br /&gt;
| Eastern Washington&lt;br /&gt;
| megafloods&lt;br /&gt;
| Most likely a reference to the {{w|Missoula floods}} and the {{w|Bonneville flood}}, a series of floods caused by glacial ice dam failures causing massive lakes to flood large regions of present-day eastern Washington. These floods actually continued all the way to the Pacific Ocean, altering the shape of the {{w|Columbia River Gorge}} and flooding much of the {{w|Willamette River}} in western Oregon. The comic may have simplified these to avoid bisecting the adjacent zones along the coast.&lt;br /&gt;
|-&lt;br /&gt;
| West Coast&lt;br /&gt;
| a plate tectonic speedrun&lt;br /&gt;
| Most likely a reference to the significant tectonic activity on the western coast of the US, caused by the collisions of the {{w|Juan de Fuca plate}}, {{w|Pacific plate}}, and the {{w|North American plate}}, as part of the {{w|Ring of Fire}}.&lt;br /&gt;
|-&lt;br /&gt;
| Southwest Desert&lt;br /&gt;
| water and time&lt;br /&gt;
| The nearly 40 major sedimentary rock layers exposed in the {{w|geology of the Grand Canyon area}} range in age from about 200 million to nearly 2 billion years old. Uplift of the region started about 75 million years ago during the mountain-building event largely responsible for creating the Rocky Mountains. The opening of the Gulf of California around 6 million years ago enabled a large river to cut its way northeast from the gulf. The new river captured the older drainage to form the ancestral Colorado River, which in turn started to form the Grand Canyon. Wetter climates brought upon by ice ages starting 2 million years ago greatly increased excavation of the Grand Canyon, which was nearly as deep 1.2 million years ago as it is now.  &lt;br /&gt;
|-&lt;br /&gt;
| Northern Alaska&lt;br /&gt;
| geology&lt;br /&gt;
| Northern {{w|Geology of Alaska|Alaska geology}} is dominated by the Brooks Range (a major Paleozoic mountain belt) and the Arctic Slope sedimentary basin, containing rich Paleozoic-Mesozoic rock sequences. The region is part of the Arctic Alaska–Chukotka Microplate, shaped by Mesozoic tectonic shifts, including the Arctic Ocean opening and the Brooks Range uplift.&lt;br /&gt;
|-&lt;br /&gt;
| Aleutian Islands&lt;br /&gt;
| volcanoes&lt;br /&gt;
| The Aleutian Islands are a continuation of the Alaskan {{w|Aleutian Range}}, and form part of the {{w|Ring of Fire}}. Most of the islands in the chain bear signs of being formed by volcanoes, and many volcanic cones still exist on the islands today.&lt;br /&gt;
|-&lt;br /&gt;
| Southeast Alaska&lt;br /&gt;
| glaciers&lt;br /&gt;
| This part of Alaska (including {{w|Glacier Bay National Park and Preserve|Glacier Bay National Park and Preserve}}) and western Canada has many glaciers that are still carving the landscape.&lt;br /&gt;
|-&lt;br /&gt;
| Hawaiian island chain&lt;br /&gt;
| volcanoes&lt;br /&gt;
| Hawaii, including the {{w|Northwest Hawaiian Islands}}, and seamounts northwest of it were formed by a tectonic plate moving over a hotspot, with volcanoes erupting and forming land as it went. The entire chain can be seen [https://www.google.com/maps/@34.0555574,-176.5939317,4904085m/data=!3m1!1e3?entry=ttu&amp;amp;g_ep=EgoyMDI2MDMxNS4wIKXMDSoASAFQAw%3D%3D here]. Volcanic fog from the {{w|List of volcanoes in the Hawaiian–Emperor seamount chain|three active volcanoes on the Big Island}} can often be seen on neighboring islands.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by A DISMEMBERED WATERSLIDE TEST DUMMY. Don't remove this notice too soon.}}&lt;br /&gt;
Low-gravity environments can cause humans and other animals to lose muscle mass, a serious problem for people staying for extended periods on the {{w|International Space Station}}. &lt;br /&gt;
&lt;br /&gt;
[[Cueball]] at first appears to be describing his experience operating a spaceship, creating {{w|Artificial_gravity#Centrifugal_force|artificial gravity by rotating the ship}} so as to preserve the passengers' muscle mass.&lt;br /&gt;
&lt;br /&gt;
However, the caption to the panel indicates that the &amp;quot;ship&amp;quot; Cueball was operating was a cruise ship, not a space ship. Since cruise ships that travel upon the seas and oceans of the Earth, experience the same gravity that they would experience at sea level on land, there is no need for &amp;quot;artificial gravity&amp;quot; aboard a cruise ship.&lt;br /&gt;
&lt;br /&gt;
Furthermore, Cueball's rotation of the ship along its longitudinal axis would involve turning the ship upside down (and then right side up again). This would likely result in many people aboard drowning. Anything on the outside of the ship that wasn't firmly attached would be lost, by the combination of drag from the water and being flung away by the centrifugal force. There's no indication of ''how'' the rotation would be created, which would be a significant undertaking given that cruise ships are generally built with some priority given to keeping them right-side-up, via things like concentrations of mass at the bottom of the hull. In contrast, objects in space do not need continuous acceleration to continue rotating, because they don't have to overcome significant drag from their environment in the way that a cruise ship partially immersed in water does.&lt;br /&gt;
&lt;br /&gt;
The title text references the earlier comic [[2935: Ocean Loop]], where Cueball made an {{w|Action Park}}'s Cannonball Loop for Cruise ships. Such loops can subject riders to [https://www.wired.com/2012/04/g-forces-in-a-looping-water-slide/ over 10g] of acceleration. Cueball complains about being fired, and says he does not understand why. Since &amp;quot;The peak acceleration for passengers was WAY lower than in the giant-waterslide-loop-the-loop incident the other cruise line fired me for.&amp;quot; This is thus the second comic where Cueball has been fired by a cruise line for his hazardous actions. In the first comic he similarly complains about the decision of the cruise line in the title text.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In this comic, [[Jill]] asks [[Cueball]] about a mark on his arm. He apparently believes he is part of a secret society, so secret that he doesn't know anything about the society. His belief in the existence of the society, and that he is a part of it, stem from one contact with an 'agent'. Most people would immediately dismiss the idea of such a secret society, especially with no evidence of its existence, and no knowledge of the goals or even whether it is inherently good or evil. &lt;br /&gt;
&lt;br /&gt;
Six years after being 'chosen', Cueball finds a scrap of paper with an address on it, and a can of {{w|kerosene}}. Both of these events are not unlikely, and easily explained as simple coincidences, but Cueball somehow sees this as a command that he must burn down the house (maybe an example of {{w|ideas and delusions of reference}}). Cueball shows that he is willing to put other people's lives at risk, destroy property and possessions, and face the possibility of prison, all because of one event six years prior.&lt;br /&gt;
&lt;br /&gt;
Cueball's belief in the society, his delusional linking of the address and kerosene, and his actions in burning down the house, show how badly he wants to be part of something bigger, and to find meaning in the &amp;quot;Chaos of Life&amp;quot;. &lt;br /&gt;
&lt;br /&gt;
The punchline refers to an old grade school/middle school prank (Urban Dictionary: [http://www.urbandictionary.com/define.php?term=pen15+club pen 15 club], [http://www.urbandictionary.com/define.php?term=pen15 Pen 15].) You'd typically walk up to an unsuspecting schoolmate and ask them if he wants to join the Pen Fifteen Club. You'd tell them that to join, you merely have to write the club name on them. You'd then write &amp;quot;PEN15&amp;quot; on their hand or arm, and everyone would laugh at them because it looks like &amp;quot;PENIS&amp;quot;. (In a common variant, it is simply called the Pen Club, 15 is the victim's &amp;quot;member number&amp;quot;, and the pranksters write &amp;quot;PEN13&amp;quot; and &amp;quot;PEN14&amp;quot; on themselves.) In this case, [[Cueball]] fell victim to this prank as a child without ever figuring out the joke, and the ink somehow never got washed off by showers or baths or removed by shedding skin. In reality, it would be unlikely for such a mark to last for so long. While methods of marking someone's skin more permanently do exist, it is hard to imagine someone tattooing or branding &amp;quot;PEN15&amp;quot; on their friend's arm as a prank. (Alternatively, Cueball has regularly redrawn PEN15 on his arm.)&lt;br /&gt;
&lt;br /&gt;
It is also possible, considering the recurrence of absurd and surrealist humor on xkcd, that this comic's PEN15 club is indeed a dark secret society working to further mysterious goals. The punchline only makes sense to the viewer, who lives in a reality where &amp;quot;the pen fifteen club&amp;quot; is a middle school prank and not an Illuminati-esque shadow organization.{{Citation needed}} Humor of this type is an example of {{w|dramatic irony}}.&lt;br /&gt;
&lt;br /&gt;
The comic's title may refer to the mark on Cueball's arm, or to the fact that he is the 'mark' (i.e. victim) of the prank, or to the owner of the house he burnt down as the 'mark' of his imagined secret society. As for the title text, {{w|solipsism}} is the philosophical idea that only your own mind is sure to exist while other minds can't be really known and so those other minds are not proved to be real. In this context it might mean that the only one who can conspire would be you, hiding the truth from yourself.&lt;br /&gt;

:Cueball: It's safer that way.&lt;br /&gt;
&lt;br /&gt;

I'm not sure if this is a UK-specific phenomenon, so it may not be familiar to many of you, but those who ''do'' do this (&amp;quot;do do&amp;quot; – snigger), ''stop it''. I refer to banging on about how spectacular the aurora is but not mentioning that it couldn't be seen with the naked eye. If you can only see it by pointing your camera at it, that's not seeing it. That's not worthy of BBC journalists saying the aurora was visible, because it ''wasn't''. That's a cute trick that your phone can do to translate invisible parts of the spectrum into visible light. You don't post UV-detector shots of patterns that birds can see and say &amp;quot;Wow, conditions were perfect for making these patterns visible on this lizard!&amp;quot; If it's not visible, it's not visible.

==Explanation==&lt;br /&gt;
{{incomplete|This page was created by a gorilla glue gorilla. Don't remove this notice too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic refers to {{w|Epoxy|epoxy}} — substances used as adhesives, sealants, and coatings. Many types of epoxy are multi-part, where the components, such as resin and a hardener, are stored separately. For ease of use, this can be in parallel syringes (of equal volume, or suitably different where a mixing ratio of 2:1 or 3:2 might be desired) such that the user simultaneously squeezes out the isolated chemicals by depressing both syringes at once. They are then mixed together on the target surface, so that the combined epoxy quickly cures into the desired solid, binding whatever surfaces upon which it is applied and then brought into contact with. This comic presents a fictitious 16-part epoxy, with the same apparent logic of parallel deposition in mind, with many components that are implausible or make fun of common problems people have when using epoxy in real life.&lt;br /&gt;
&lt;br /&gt;
The title text references how not all epoxies and glues work on every material, and that applying them on some can require special techniques or products. Some industrial or industrial-grade adhesives contain solvents (e.g. {{w|tetrachloroethylene}}, which is used in E6000 glue) that release harmful vapors as they cure. If used improperly, this can result in the release of chemical vapors in an enclosed space along other dangerous side-effects, while also not working as a glue as intended.&lt;br /&gt;

|{{Yes}}&lt;br /&gt;
|While this looks like a joke entry, this is actually an alternative to resin which is extracted naturally rather than synthesized from other chemicals. Rosin is frequently applied to the bows of string instruments like violins or cellos to improve the sound, as immortalized in the famous song &amp;quot;The Devil Went Down to Georgia&amp;quot;.&lt;br /&gt;

|Stuff that bonds permanently to skin and nothing else&lt;br /&gt;
|{{No}}&lt;br /&gt;
|One key annoyance with sticky substances is the difficulty of removing them when they bond to skin. In this case, the polymer bonds solely to skin instead of anything else, making it mostly only really useful for a practical joke. Some epoxies are specifically designed for gluing skin, usually for medical purposes, but none are known to bond to skin exclusively.{{acn}}&lt;br /&gt;

This may be a reference to cyanoacrylate adhesives, which famously bond quite aggressively to skin, while often failing to bond the target materials. &lt;br /&gt;
|-&lt;br /&gt;
|Stuff that will crack and turn white over a few days, for decorative appearance&lt;br /&gt;
|{{Maybe|Not effective as epoxy}}&lt;br /&gt;
|'Crackle effect' is a real thing for crafters, and can be created by mixing paint and glue, but is not recommended if you want two surfaces to adhere, since most paint is made to be non-adherent in order to be durable{{acn}}. Poor finish, where an intended smooth uniform surface cracks or discolours, can be a frustrating problem when applying epoxy mixtures to visible surfaces, especially when the problem only appears some time after you've congratulated yourself on a job well-done.&lt;br /&gt;
|-&lt;br /&gt;
|Placebo&lt;br /&gt;
|{{Maybe|Not in the field of adhesives}}&lt;br /&gt;
|The {{w|placebo effect}} happens when somebody is told that something has a certain effect, when in reality there is no effect. This is commonly used in medical studies to determine whether a medication actually does something as opposed to simply having a {{w|psychosomatic effect}}. Using this term to describe a type of polymer suggests it would make someone believe it is gluing things together without actually doing anything, which is unlikely. Alternatively, this could refer to a component or filler that claims to serve a specific purpose while having no true benefit, causing the perception of benefit to the consumer (presumably causing better reviews).&lt;br /&gt;
|-&lt;br /&gt;
|Minced duct tape&lt;br /&gt;
|{{Maybe|Not intentionally}}&lt;br /&gt;
|{{w|Duct tape}} is widely used as a way to join and/cover things, sometimes in contexts where an epoxy might provide a more high-quality solution. [[Randall]] is pretending that having very small pieces of tape in the mix would add to the epoxy's ability to hold things together. In reality, cutting duct tape into small pieces would weaken it and make it ''less'' effective at sticking things together. In the UK, the word 'minced' can also mean 'made worthless', which would also not fare well for the adhesive.&lt;br /&gt;
|-&lt;br /&gt;
|Acetone fragrance&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Acetone is a volatile solvent used in a number of glues and paints (incl. nail polish), but it weakens epoxy and can even be used to remove uncured epoxy. It has a strong, distinctive, very unpleasant smell, and is actually toxic, meaning that fragrance is an odd reason for adding it to any product. It's likely being added here to give the epoxy a familiar &amp;quot;chemical smell&amp;quot; that people associate with industrial compounds.&lt;br /&gt;
|-&lt;br /&gt;
|Powdered bar magnets&lt;br /&gt;
|{{Maybe|Yes, but not in resin}}&lt;br /&gt;
|This might still work if the pieces could somehow be aligned correctly, as each tiny piece of magnet would still be a magnet in its own right, capable of attracting the other tiny magnets, and thus resisting tension forces. However, it would be much worse than a normal bar magnet, since the magnetic force would be weaker than those that held the original bar together. The micro-magnets would tend to clump together, which might strengthen the glue, but wouldn't help it to bond to surfaces very much unless the surfaces themselves were strongly magnetic.&lt;br /&gt;
|-&lt;br /&gt;
|Polyethylvinylesteracetate&lt;br /&gt;
|{{Maybe|Not in epoxy}}&lt;br /&gt;
|This appears to be a reference to {{w|ethylene-vinyl acetate|Poly (ethylene-vinyl acetate)}}, some formulations of which can be used as the adhesive in hot-glue guns. Vinyl acetate is an ester, so the inclusion of that term is redundant. The cadence of the constructed word may also be a reference to the television episode {{w|Lucy Does a TV Commercial}} and its memorable product &amp;quot;Vitameatavegamin&amp;quot;. It also resembles the kind of thing often seen in ingredients lists for common household products such as soaps and cleaners, which are fairly meaningless to the average person buying them.&lt;br /&gt;
|-&lt;br /&gt;
|2-Polyethylvinylesteracetate&lt;br /&gt;
|{{Maybe|Unclear}}&lt;br /&gt;
|This sounds almost exactly the same as the above item, but {{w|2-Polyprenyl-6-hydroxyphenol methylase|a name with a &amp;quot;2-&amp;quot; prefix}} generally indicates that the initial bit of the name is a {{w|functional group}} attached to the ''second'' position along a chemical chain (often being the carbon-carbon 'spine' of a molecule, in large-molecule organic chemistry), rather than attached to its end. Because the molecule name is (possibly deliberately) malformed, it's hard to tell what is supposed to be attached to the second carbon of what subunit.&lt;br /&gt;
|-&lt;br /&gt;
|Salt and pepper to taste&lt;br /&gt;
|{{Maybe|Not for taste, but salt can be useful}}&lt;br /&gt;
|Salt and pepper are two incredibly popular condiments which are used to enhance a dish's flavor, and &amp;quot;salt and pepper to taste&amp;quot; is a phrase found in many (food) recipes. But the taste of your epoxy should not be your concern. Do not eat epoxy. But salt or sand or other fine grains are sometimes recommended to add a bit of grit to an adhesive. Generally glues or epoxies need the bonded materials to be firmly held together while the glue cures. But when first pressed together, any excess glue is squeezed out and can cause the surfaces to slip around and need to be re-aligned. Any extra friction in the epoxy can help alleviate that.&lt;br /&gt;
|-&lt;br /&gt;
|Blood sample from the Gorilla Glue gorillas&lt;br /&gt;
|{{No}}{{Citation Needed}}&lt;br /&gt;
|{{w|Gorilla Glue}} is a popular brand of superglue which uses {{w|gorillas}} as its mascot. In this case, the blood of the gorillas would be extracted and placed in the polymer, which would not be any more efficacious than any other gorilla's blood; insofar as Gorilla Glue gorillas exist, they are depicted as ordinary gorillas who just happen to carry glue everywhere. Extracting and consuming the blood of a creature or person in an attempt to inherit some of the qualities of the 'donor' is a common trope, so this may be suggesting that including this will give the epoxy 'the strength of a gorilla', commonly considered a powerful animal.&lt;br /&gt;
&lt;br /&gt;
Blood has been [https://www.sciencedirect.com/topics/engineering/blood-glue historically used in glue], though not typically that of gorillas.&lt;br /&gt;
|-&lt;br /&gt;
|Stuff that bonds to every known material except yours&lt;br /&gt;
|{{No|Probably not}}&lt;br /&gt;
|Another common annoyance when using an adhesive is that each glue type only forms an adhesive bond with certain materials. In this case, the polymer would bond with every material except for the one you were using, causing great distress and leaving you in a fix.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by the birds flying in my kite. Don't remove this notice too soon.}}&lt;br /&gt;
This comic shows the side profiles of a variety of different sailing boat/ship rigs, starting with six real ones, but then moving mostly into ones imagined by [[Randall]], with varying levels of absurdity. The [[#The Rigs|table below]] explains each type depicted.&lt;br /&gt;
&lt;br /&gt;
The title text is a pun on {{w|Catch-22 (logic)|Catch-22}}, which is a term (taken from the novel of the same name) for a situation where success is impossible because it requires meeting contradictory conditions. For example, in the novel, the term was used by military pilots who qualified to be released from combat duty, but were ordered to fly additional missions, and were told that disobeying those orders was grounds to have their releases revoked, which would require them to fly additional missions anyway. &lt;br /&gt;
&lt;br /&gt;
Per the main panel, a ketch is similar to a yawl but has a larger aft sail, so increasing the aft sail of a yawl effectively turns the yawl into a ketch, effectively making it impossible to build a faster yawl. However, this is not technically true, as the distinction between a {{w|yawl}} and {{w|ketch}} is based on whether the aft sail is mounted forward or aft of the rudder post (although a yawl with a large aft sail may be difficult to control).{{actual citation needed}}&lt;br /&gt;

|[[File:3193 Lateen.png|200x200px]]&lt;br /&gt;
|{{Yes}} &lt;br /&gt;
|A single triangular sail.&lt;br /&gt;
|The triangular sail is affixed to a long yard or crossbar, mounted at its middle to the top of the mast and angled to extend aft far above the mast and forward down nearly to the deck. The sail, its free corner secured near the stern, is capable of taking the wind on either side, and, by enabling the vessel to tack into the wind, the [https://www.britannica.com/technology/lateen-sail lateen] immensely increases the potential of the sailing ship. &amp;lt;!-- It doesn't say this in the Wikipedia --&amp;gt;&lt;br /&gt;

|A front and rear triangular sail share a mast.&lt;br /&gt;
|A {{w|sloop}} has one mast, typically with two sails mounted on the mast, one ahead and one behind.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Ketch}}&lt;br /&gt;
|[[File:3193 Ketch.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A sailboat with two masts, where the main mast is taller than the mizzen (or aft mast), and the mizzen is forward of the rudder post&lt;br /&gt;
|Similar to a yawl&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Gaff rig|Gaff rigged sloop}}&lt;br /&gt;
|[[File:3193 Gaff Sloop.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A front triangular sail shares a mast with a rear quadrilateral sail.&lt;br /&gt;
|A sloop is a sailboat with one mast, typically with two sails mounted on it — one ahead and one behind. A [https://nauticalknowhow.mysailingcourse.com/glossary/gaff-rig/ gaff rig] is a sailing rig where one sail is four-sided and controlled by a spar (the gaff) at its top, which is hoisted at an angle to the mast.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Yawl}}&lt;br /&gt;
|[[File:3193 Yawl.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|Two triangular sails share a front mast, and a much smaller aft mast holds a small aft sail.&lt;br /&gt;
|A yawl is sailboat with two masts, where the main mast has two sails (one in front of the mast and one behind, known as {{w|Fore-and-aft rig|fore-and-aft rigging}}, and the mizzen mast is mounted aft of the rudder post, leading the mizzen sail to typically be small. Similar to a ketch.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Schooner}}&lt;br /&gt;
||[[File:3193 Schooner.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A sailboat with two or more masts, where all have {{w|Fore-and-aft rig|fore-and-aft rigging}}, and where the foremast is typically smaller than the main mast&lt;br /&gt;
|-&lt;br /&gt;
|Ketch-rigged gaff&lt;br /&gt;
|[[File:3193 Ketch Gaff.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Resembles a gaff, with the aft sail reduced and two triangular sails mounted above. The resulting shape resembles a vertical ketch.&lt;br /&gt;
|The first fictional rig. It might be capable of functioning like a sloop, but its rigging would be more complicated and it is likely less efficient at catching the wind.&lt;br /&gt;
|-&lt;br /&gt;
|Kloop-rigged sketch&lt;br /&gt;
|[[File:3193 Kloop.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Four or five sails mounted in a nonsensical configuration, with elements from the schooner, ketch, and gaff&lt;br /&gt;
| A mixture of the names of {{w|ketch}} and {{w|sloop}}, poking fun at the unfamiliar and odd-sounding names of some rigs. Adding to the absurdity, the kloop-rigged sketch is neither a sloop nor a ketch. However it is technically a {{w|Sketch (drawing)|sketch}}, as &amp;quot;sketch&amp;quot; can mean &amp;quot;drawing&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|Bunkbed rig&lt;br /&gt;
|[[File:3193 100% more boat.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|A gaff-rigged sloop mounted on top of a second hull.&lt;br /&gt;
|The name refers to a {{w|bunkbed}}, where one bed is mounted directly above another. Bunk-style sleeping arrangements are sometimes used on boats for reasons of space efficiency. It applies this idea to the whole ship, mounting one hull directly above another. While {{w|Multihull|boats with multiple hulls}} do exist, these are always mounted side-by-side to guarantee stability. Mounting one hull above another would be a terrible idea, as the upper hull would be ineffective when raised above the water, the lower hull might become submerged and sink, and such a tall boat would be unstable, causing it to fall over. The comic is funny{{cn}} due to this {{w|surreal humour|absurdity}}, due to the boat's obviously extreme design being so far outside what someone would expect a boat to look like.&lt;br /&gt;
Notably, this ship's ''rigging'' is mundane; the connection between hulls seems to be structural. It may be more accurate to refer to it as a bunkbed ''hull''.&lt;br /&gt;
|-&lt;br /&gt;
|Flettner rig&lt;br /&gt;
|[[File:3193 Flettner.png|200x200px]]&lt;br /&gt;
|{{Yes}}, though not typically called a rig&lt;br /&gt;
|The rectangular outline of a cylinder with motion lines around it, indicating a {{w|Flettner rotor}}&lt;br /&gt;
|A Flettner rotor is a right circular cylinder with disc end plates which is spun along its long axis. As air passes across it the {{w|Magnus effect}} causes an aerodynamic lift force to be generated in the direction perpendicular to both the long axis and the direction of airflow. In a {{w|rotor ship}}, the rotors stand vertically and lift is generated at right angles to the wind, to drive the ship forwards. &lt;br /&gt;
&lt;br /&gt;
Flettner rotors were previously mentioned in [[3119]]&lt;br /&gt;
|-&lt;br /&gt;
|Oops, all spinnakers&lt;br /&gt;
|[[File:3193 Spinnakers.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Three masts each with a sail billowing in front&lt;br /&gt;
|A {{w|spinnaker}} is a real type of sail, where a boat is propelled by a large sail directly pulled by the wind, similar in principle to a parachute. However, &amp;quot;Oops, all spinnakers&amp;quot; is not real, as spinnakers are only practical for smaller craft, and if multiple spinnakers are mounted in a row the earlier ones may disrupt the airflow to the later ones. It does not appear that there are any real boats propelled by more than one spinnaker.&lt;br /&gt;
The name of the rig is a reference to the {{w|Cap'n Crunch}} cereal type that became a meme, [https://knowyourmeme.com/memes/oops-all-berries-box-parodies ''Oops! All Berries''], which has also been referenced in [[2256]] and [[2719]]. &lt;br /&gt;
|-&lt;br /&gt;
|Keel rig&lt;br /&gt;
|[[File:3193 Keel.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Three sails in a ketch arrangement, but mounted to the keel, which would typically put the ''sails underwater''.&lt;br /&gt;
|The book {{w|Heaven (Stewart and Cohen novel)|''Heaven''}}, by Ian Stewart and Jack Cohen, features an aquatic protagonist who is introduced as sailing a surface craft with underwater 'sails' (and above-water 'keel'), due to the switched nature of his usual environment.&lt;br /&gt;
|-&lt;br /&gt;
|Kite rig&lt;br /&gt;
|[[File:3193 Kite.png|200x200px]]&lt;br /&gt;
|{{Maybe|Kind of}} &lt;br /&gt;
|All sails are replaced by two groups of kites, each tied to the mast with their own independent line.&lt;br /&gt;
|A {{w|kite rig}} is a real thing, where a kite is deployed from a boat or ship to catch the wind and pull the vessel along. This rigging is used in various types of vessel, most commonly {{w|kite surfing}}, but occasionally other vessels too, up to [https://edition.cnn.com/2023/06/30/travel/airseas-giant-kites-ships-slash-carbon-emissions-scn-climate-spc trials with cargo ships].&lt;br /&gt;
However, the real kite riggings typically use one large kite optimised for catching the wind, rather than many small kites optimised for flying (as depicted) which would likely get tangled and not pull much on the ship.&lt;br /&gt;
|-&lt;br /&gt;
|Longsail rig&lt;br /&gt;
|[[File:3193 Longsail.png|300x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|A Bermuda rigged sloop with the aft sail extending ~5 times as far back, well beyond the end of the hull.&lt;br /&gt;
|While not technically impossible, such a long sail would likely be susceptible to damage from the wind, as well as potentially making it hard to control the boat.&lt;br /&gt;
This design could be a reference to &amp;quot;{{w|Cargo bike#Longtail bicycle|long-tail bikes}}&amp;quot;, a type of cargo bicycle useful for hauling heavy or voluminous charges at the cost of higher weight and reduced manoeuvrability.&lt;br /&gt;
|-&lt;br /&gt;
|Deckhand obliterator&lt;br /&gt;
|[[File:3193 Deckhand Obliterator.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|All sails replaced by an anchor that swings from the mast on a chain. &lt;br /&gt;
|Any deckhands (crew) on the deck could be knocked off or fatally hurt if the anchor passes through their space. While most captains would consider this counterproductive, it might be effective at its stated purpose.&lt;br /&gt;
There is a risk that the anchor might damage the mast in a collision or get wrapped around it. It would be of little use as far as propulsion is concerned.&lt;br /&gt;
|-&lt;br /&gt;
|Offset rig&lt;br /&gt;
|[[File:3193 Offset.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Gaff rigged sloop sails are mounted on a mast that is offset (forward) from the hull via an underwater extension of the keel.&lt;br /&gt;
|The extreme mechanical advantage of the sail, potentially combined with the uneven weight, would make this rigging hard if not impossible to control.&amp;lt;br&amp;gt;&lt;br /&gt;
There are in fact [https://junkrigassociation.org/technical_forum/470838 sail configurations] called [https://www.boatdesign.net/threads/gaffs-balanced-lugs-hoyt-offset-rig-etc.53504/ offset rigs] but they aren't like the one shown here.&lt;br /&gt;
|-&lt;br /&gt;
|Mastless rig&lt;br /&gt;
|[[File:3193 Mastless.png|200x200px]]&lt;br /&gt;
|{{Maybe|Kind of}}&lt;br /&gt;
|A single sail is attached directly to the hull of the boat, without any mast to give it form.&lt;br /&gt;
|As depicted, the sail would provide little to no useful propulsion, as it would not be high enough to effectively catch the wind, and would, in any case, flap unpredictably.&lt;br /&gt;
However, ships do exist without masts, such as ships not powered by wind or, more rarely, inflatable sails (e.g. [http://inflatedwingsails.com/en/concept/ this concept]), which use air, rather than a mast, for rigidity. While not intentional, it is conceivable that the drawing depicts an inflatable sail in its deflated state.&lt;br /&gt;
|-&lt;br /&gt;
|Unclassifiable chaos rig&lt;br /&gt;
|[[File:3193 Unclassifiable Chaos.png|200x200px]]&lt;br /&gt;
|{{Maybe|Arguably}}&lt;br /&gt;
|Includes elements of the schooner, yawl, lateen, and possibly others, including a sail mounted in an unusual position beneath the prow.&lt;br /&gt;
|While this specific rig is almost certainly fictional, there are many ways to rig a ship, some of which are chaotic and difficult to classify.&lt;br /&gt;

|The triangular sail is affixed to a long yard or crossbar, mounted at its middle to the top of the mast and angled to extend aft far above the mast and forward down nearly to the deck.

|-&lt;br /&gt;
|{{w|Ketch}}&lt;br /&gt;
|[[File:3193 Ketch.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A sailboat with two masts, where the main mast is taller than the mizzen (or aft mast), and the mizzen is forward of the rudder post&lt;br /&gt;
|Similar to a Yawl&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Gaff rig|Gaff rigged sloop}}&lt;br /&gt;
|[[File:3193 Gaff Sloop.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A front triangular sail shares mast with rear quadrilateral sail.&lt;br /&gt;
|A sloop is a sailboat with one mast, typically with two sails mounted on the mast, one ahead and one behind. A [https://nauticalknowhow.mysailingcourse.com/glossary/gaff-rig/ gaff Rig] is a sailing rig where one sail is four-sided and controlled by a spar (the gaff) at its top, which is hoisted at an angle to the mast.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Yawl}}&lt;br /&gt;
|[[File:3193 Yawl.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|Two triangular sails share a front mast, and a much smaller aft mast holds a small aft sail.&lt;br /&gt;
|A Yawl is sailboat with two masts, where the main mast has two sails (One in front of the mast and one behind, known as {{w|fore-and-aft rigging}}, and the mizzen mast is mounted aft of the rudder post, leading the mizzen sail to typically be small. Similar to a Ketch.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Schooner}}&lt;br /&gt;
||[[File:3193 Schooner.png|200x200px]]&lt;br /&gt;
|{{Yes}}&lt;br /&gt;
|A sailboat with two or more masts, where all have {{w|fore-and-aft rigging}}, and where the foremast is typically smaller than the main mast&lt;br /&gt;
|-&lt;br /&gt;
|Ketch-rigged gaff&lt;br /&gt;
|[[File:3193 Ketch Gaff.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Resembles a gaff, with the aft sail reduced and two triangular sails mounted above. The resulting shape resembles a vertical ketch.&lt;br /&gt;
|The first fictional rig. It might be capable of functioning like a sloop, but its rigging would be more complicated and it is likely less efficient at catching the wind.&lt;br /&gt;
|-&lt;br /&gt;
|Kloop-rigged sketch&lt;br /&gt;
|[[File:3193 Kloop.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Four or five sails mounted in a nonsensical configuration, with elements from the schooner, ketch, and gaff&lt;br /&gt;
| A mixture of the names of {{w|ketch}} and {{w|sloop}}, poking fun at the unfamiliar and odd-sounding names of some rigs. Adding to the absurdity, the kloop-rigged sketch is neither a sloop nor a ketch. However it is technically a {{w|Sketch (drawing)|sketch}}, as &amp;quot;sketch&amp;quot; can mean &amp;quot;drawing&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|Bunkbed rig&lt;br /&gt;
|[[File:3193 100% more boat.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|A gaff-rigged sloop mounted on top of a second hull.&lt;br /&gt;
|The name refers to a {{w|bunkbed}}, where a bed is mounted directly above another, and applies this idea to a ship, mounting a hull directly above another. While {{w|Multihull|boats with multiple hulls}} do exist, these are always mounted side-by-side to guarentee stability. Mounting a hull above another would be a terrible idea, as the upper hull would be ineffective when raised above the water, the lower hull might become submerged and sink, and such a tall boat would be unstable causing it to fall over. The comic is funny due to this {{w|surreal humour|absurdity}}, due to boat's obivously extreme design being so far outside what someone would expect a boat to look like.&lt;br /&gt;
Notably, this ship's ''rigging'' is mundane; the connection between hulls seems to be structural. It may be more accurate to refer to it as a bunkbed ''hull''.&lt;br /&gt;
|-&lt;br /&gt;
|Flettner rig&lt;br /&gt;
|[[File:3193 Flettner.png|200x200px]]&lt;br /&gt;
|{{Yes}}, though not typically called a rig&lt;br /&gt;
|The rectangular outline of a cylinder with motion lines around it, indicating a {{w|Flettner rotor}}&lt;br /&gt;
|A Flettner rotor is a right circular cylinder with disc end plates which is spun along its long axis. As air passes across it the {{w|Magnus effect}} causes an aerodynamic lift force to be generated in the direction perpendicular to both the long axis and the direction of airflow. In a {{w|rotor ship}}, the rotors stand vertically and lift is generated at right angles to the wind, to drive the ship forwards. &lt;br /&gt;
&lt;br /&gt;
Flettner rotors were previously mentioned in [[3119]]&lt;br /&gt;
|-&lt;br /&gt;
|Oops, all spinnakers&lt;br /&gt;
|[[File:3193 Spinnakers.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Three masts each with a sail billowing in front&lt;br /&gt;
|A {{w|spinnaker}} is a real type of sail, where a boat is propelled by a large sail directly pulled by the wind, similar in principle to a parachute. However, &amp;quot;Oops, all spinnakers&amp;quot; is not real, as spinnakers are only practical for smaller craft, and if multiple spinnakers are mounted in a row the earlier ones may disrupt the airflow to the later ones{{citation needed}}. It does not appear that there are any real boats propelled by more than one spinnaker.{{citation needed}}&lt;br /&gt;
The name of the rig is a reference to the {{w|Cap'n Crunch}} cereal type that became a meme, [https://knowyourmeme.com/memes/oops-all-berries-box-parodies ''Oops! All Berries''], which has also been referenced in [[2256]] and [[2719]]. &lt;br /&gt;
|-&lt;br /&gt;
|Keel rig&lt;br /&gt;
|[[File:3193 Keel.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Three sails in a ketch arrangement, but mounted to the keel, which would typically put the ''sails underwater''.&lt;br /&gt;
|The book {{w|Heaven (Stewart and Cohen novel)|''Heaven''}}, by Ian Stewart and Jack Cohen, features an aquatic protagonist who is introduced as sailing a surface-craft with underwater-'sails' (and above-water 'keel'), due to the switched nature of his usual environment.&lt;br /&gt;
|-&lt;br /&gt;
|Kite rig&lt;br /&gt;
|[[File:3193 Kite.png|200x200px]]&lt;br /&gt;
|{{Maybe|Kind of}} &lt;br /&gt;
|All sails are replaced by two groups of kites, each tied to the mast with their own independent line.&lt;br /&gt;
|A {{w|kite rig}} is a real thing, where a kite is deployed from a boat or ship to catch the wind and pull the vessel along. This rigging is used in various types of vessel, most commonly {{w|kite surfing}}, but occasionally other vessels too, up to [https://edition.cnn.com/2023/06/30/travel/airseas-giant-kites-ships-slash-carbon-emissions-scn-climate-spc trials with cargo ships]. However, the real kite riggings typically use one large kite optimised for catching the wind, rather than many small kites optimised for flying (as depicted) which would likely get tangled and not pull much on the ship.&lt;br /&gt;
|-&lt;br /&gt;
|Longsail rig&lt;br /&gt;
|[[File:3193 Longsail.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|A bermuda rigged sloop with the aft sail extending ~5 times as far back, well beyond the end of the hull.&lt;br /&gt;
|While not technically impossible, such a long sail would likely be suceptiple to damage from the wind, as well as potentially making it hard to control the boat. This design could be a reference to &amp;quot;{{w|Cargo bike#Longtail bicycle|long-tail bikes}}&amp;quot;, a type of cargo bicycle useful for hauling heavy or voluminous charges at the cost of higher weight and reduced manoeuvrability.&lt;br /&gt;
|-&lt;br /&gt;
|Deckhand obliterator&lt;br /&gt;
|[[File:3193 Deckhand Obliterator.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|All sails replaced by an anchor that swings from the mast on a chain. &lt;br /&gt;
|Any deckhands (crew) on the deck could be knocked off or fatally hurt if the anchor passes through their space. While most captains would consider this counterproductive, it would likely be effective at its stated purpose.&lt;br /&gt;
|-&lt;br /&gt;
|Offset rig&lt;br /&gt;
|[[File:3193 Offset.png|200x200px]]&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Gaff rigged sloop sails are mounted on a mast that is offset (forward) from the hull via an underwater extension of the keel.&lt;br /&gt;
|The extreme mechanical advantage of the sail, potentially combined with the uneven weight, would make this rigging hard if not impossible to control.&amp;lt;br&amp;gt;&lt;br /&gt;
There are in fact [https://junkrigassociation.org/technical_forum/470838 sail configurations] called [https://www.boatdesign.net/threads/gaffs-balanced-lugs-hoyt-offset-rig-etc.53504/ offset rigs] but they aren't like the one shown here.&lt;br /&gt;
|-&lt;br /&gt;
|Mastless rig&lt;br /&gt;
|[[File:3193 Mastless.png|200x200px]]&lt;br /&gt;
|{{Maybe|Kind of}}&lt;br /&gt;
|A single sail is directly to the hull of the boat, without any mast holding it in the wind.&lt;br /&gt;
|As depicted the sail would provide little to no useful propulsion, as it would not be high enough to effectively catch the wind. However ships do exist without sails, such as ships not powered by wind{{citation needed}}, or more rarely inflatable sails (e.g. [http://inflatedwingsails.com/en/concept/ this concept]), which use air rather than a mast for rigidity. While not intentional, it is conceivable that the drawing depicts an inflatable sail in its deflated state.&lt;br /&gt;
|-&lt;br /&gt;
|Unclassifiable chaos rig&lt;br /&gt;
|[[File:3193 Unclassifiable Chaos.png]]&lt;br /&gt;
|{{Maybe|Arguably}}&lt;br /&gt;
|Includes elements of the schooner, yawl, lateen, and possibly others.&lt;br /&gt;
|While this specific rig is almost certainly fictional, there are many ways to rig a ship, some of which are difficult to classify.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
The title text is a pun on the term {{w|Catch-22 (logic)|Catch-22}}, which is a term (taken from the novel of the same name) for a situation where success is impossible because it requires meeting contradictory conditions. For example, in the novel, the term was used by military pilots who qualified to be released from combat duty, but were ordered to fly additional missions, and were told that disobeying those orders was grounds to have their releases revoked, which would require them to fly additional missions anyway. &lt;br /&gt;
&lt;br /&gt;
Per the main panel, a ketch is similar to a yawl but has a larger aft sail, so increasing the aft sail of a yawl effectively turns the yawl into a ketch, effectively making it impossible to build a faster yawl. However this is not technically true, as the distinction between a {{w|yawl}} and {{w|ketch}} is based on whether the aft sail is mounted forward or aft of the rudder post, although a yawl with a large aft sail may be difficult to control.{{actual citation needed}}&lt;br /&gt;

|Kite rig&lt;br /&gt;
|{{Maybe|Kind of}} &lt;br /&gt;
|All sails are replaced by two groups of kites, each tied to the mast with their own independent line.&lt;br /&gt;
|A {{w|kite rig}} is a real thing, where a kite is deployed from a boat or ship to catch the wind and pull the vessel along. This rigging is used in various types of vessel, most commonly {{w|kite surfing}}, but occasionally other vessels too, up to trials with cargo ships [https://edition.cnn.com/2023/06/30/travel/airseas-giant-kites-ships-slash-carbon-emissions-scn-climate-spc]. However, the real kite riggings typically use one large kite optimised for catching the wind, rather than many small kites optimised for flying (as depicted) which would likely get tangled and not pull much on the ship.&lt;br /&gt;
|-&lt;br /&gt;
|Longsail rig&lt;br /&gt;
|{{No}}&lt;br /&gt;
|A bermuda rigged sloop with the aft sail extending ~5 times as far back, well beyond the end of the hull.&lt;br /&gt;
|While not technically impossible, such a long sail would likely be suceptiple to damage from the wind, as well as potentially making it hard to control the boat.&lt;br /&gt;
|-&lt;br /&gt;
|Deckhand obliterator&lt;br /&gt;
|{{No}}&lt;br /&gt;
|All sails replaced by an anchor that swings around the mast on a chain, similar to tetherball. &lt;br /&gt;
|Any deckhands (crew) on the deck could be knocked off or fatally hurt if the anchor passes through their space.&lt;br /&gt;
|-&lt;br /&gt;
|Offset rig&lt;br /&gt;
|{{No}}&lt;br /&gt;
|Gaff rigged sloop sails are mounted on a mast that is offset (forward) from the hull via an underwater extension of the keel.&lt;br /&gt;
|The extreme mechanical advantage of the sail, potentially combined with the uneven weight, would make this rigging hard if not impossible to control.&lt;br /&gt;
|-&lt;br /&gt;
|Mastless rig&lt;br /&gt;
|{{Maybe|Kind of}}&lt;br /&gt;
|A single sail is directly to the hull of the boat, without any mast holding it in the wind.&lt;br /&gt;
|As depicted the sail would provide little to no useful propulsion, as it would not be high enough to effective catch the wind. However ships do exist without sails, such as ships not powered by wind{{citation needed}}, or more rarely inflatable sails (e.g. [http://inflatedwingsails.com/en/concept/]), which use air rather than a mast for rigidity. While not intentiional, it is concievable that the drawing depicts an inflatable sail in its deflated state.&lt;br /&gt;

|Unclassifiable chaos rig&lt;br /&gt;
|{{No|Arguably}}&lt;br /&gt;
|Includes elements of the schooner, yawl, lateen, and possibly others.&lt;br /&gt;
|While this specific rig is almost certainly fictional, there are many ways to rig a ship, some of which are difficult to classify.&lt;br /&gt;

&lt;br /&gt;
The title text is a pun on a {{w|Catch-22 (logic)|Catch-22}}, a no-win situation in which the thing needed to succeed would cause it not to succeed or not to be necessary. For instance, &amp;quot;the only way to qualify for a loan is to prove to the bank that you do not need a loan.&amp;quot; Per the main panel, a ketch is similar to a yawl but has a larger aft sail, so increasing the aft sail of a yawl effectively turns the yawl into a ketch. However this is not technically true, as the distinction between a {{w|yawl}} and {{w|ketch}} is based on whether the aft sail is mounted forward or aft of the rudder post, although a yawl with a large aft sail may be difficult to control.{{actual citation needed}}&lt;br /&gt;

Question: Would a correct interpretation be &amp;quot;if a champion jumping frog were to be located just under 1.5 light-days from earth, and if there we're no other gravitational bodies nearby, and if said frog then performed its mightiest jump directly away from earth, then the frog would eventually be overcome by Earth's gravitational field and would eventually land on Earth's surface&amp;quot;? [[User:Pgn674|Pgn674]] ([[User talk:Pgn674|talk]]) 06:26, 16 December 2025 (UTC)&lt;br /&gt;
:I guess that is exactly how it should be interpreted. Or more interesting if it was just outside this radius and somehow could gain exactly 4,5 m/s extra speed then it would escape Earth (if there was anything to push of against that was heavy enough to move basically only the frog forward, then that would change the mass behind the frog so... That was why I wrote gain exactly rather than jump).  --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:36, 16 December 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
: or its mightiest jump in any direction (that doesn't cause it to crash through the Earth) since the escape speed is the same in all directions (relevant xkcd:https://what-if.xkcd.com/68/ ) --[[Special:Contributions/178.197.223.163|178.197.223.163]] 09:21, 16 December 2025 (UTC)&lt;br /&gt;

The only two variables are rjf and M, so plotting a 2 axis graph plotting the relationship between M and rjf should be possible.

&lt;br /&gt;
As frogs usually collect on the surface of worlds {{cn}}, the *surface* escape velocity is most important. The crossover point for a planet with earth-like density (5515 kg/m³) is 2.6km, above that, the rjf falls below the surface, and the planet can accumulate frogs. Smaller bodies are, however, usually less dense; an interesting borderline candidate is Chicxulub,  which had an rjf of 3-4km, and a radius of 5-6km so could have just about held onto its frogs, for a while at least.

It would be interesting to look at the R&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt; values ''of a frog'', to consider where new limits are put upon the frog for M-masses that aren't totally dominating the scenario of &amp;quot;frog leaves mass&amp;quot;...

I interpreted it as a reference to the Mark Twain short story The Celebrated Jumping Frog of Calaveras County. [[User:Gustaveeiffel314|Gustaveeiffel314]] ([[User talk: Gustaveeiffel314|talk]]) 12:25, 16 December&lt;br /&gt;
&lt;br /&gt;
I also suspected an allusion to Twain's short story, but then I read it at archive.org/details/celebratedjumpin00twai and found no parallels. The earth's radius wasn't the problem, it was 5 pounds of quail shot. That frog didn't land with a &amp;quot;plop&amp;quot; but &amp;quot;as solid as a gob of mud.&amp;quot; There is no mention of &amp;quot;champion&amp;quot; in the story. The 1865 population of Calaveras County (post Gold Rush) was down below 15,000. That is, the frog shown in #3181 probably came from somewhere else that really knows how to breed frogs with muscular legs, maybe France. Before I risk overthinking this, I'm going to conclude that #3181 is not a Twain reference. [[User:Bismuthfoot|Bismuthfoot]] ([[User talk:Bismuthfoot|talk]]) 14:37, 16 December 2025 (UTC)&lt;br /&gt;

What's with all that text in the incomplete explanation warning box? It seems like it belongs in the discussion. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:05, 16 December 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Erm, the current text has a statement that rjf &amp;lt; 4.5m/s for other planetary bodies. Seems like it is mixing measurements, a radius would be a distance, not a velocity. It might be trying to say that other planetary bodies have an ESCAPE VELOCITY of more than 4.5 m/s, so jumping frogs on the surface of those planetary bodies couldn't get out of that planet's gravity well. ~~{{unsigned ip|57.140.32.36|15:53, 16 December 2025}}&lt;br /&gt;
:Don't recognise your statement (until I check the current state of the main explanation), but a radius can be defined as a vector, as can a velocity. Pretty sure that's not what it says (or should be saying), but there is a possible interchangability if analysed in the 'right' way.

&lt;br /&gt;
It might be worth pointing out that frogs found on the surfaces of other planets in our solar system will have other reasons for not being able to jump to escape velocity (eg., they are no longer alive) [[Special:Contributions/2A09:BAC2:6188:123C:0:0:1D1:CF|2A09:BAC2:6188:123C:0:0:1D1:CF]] 01:20, 17 December 2025 (UTC)&lt;br /&gt;

::A mechanical frog couldn't be a ''champion'' jumping frog though, because only biological frogs are allowed to compete. [[Special:Contributions/76.22.93.146|76.22.93.146]] 03:38, 17 December 2025 (UTC)&lt;br /&gt;

&lt;br /&gt;
I disagree with the point about the flawed argument of frogs all being on earth. With a simple assumption that no aliens have transported a frog off world, basic taxonomy says that anything resembling a frog on another planet would infact not be a frog and would be a result of convergent evolution. I also think that aliens moving stuff around is not a common inclusion in physics formulas. So perhaps still falwed but not as strongly flawed as implied in the main text. [[Special:Contributions/2001:14BA:A086:FF00:39D0:B88:A6EF:5F9C|2001:14BA:A086:FF00:39D0:B88:A6EF:5F9C]] 08:28, 17 December 2025 (UTC)&lt;br /&gt;
: That doesn't negate the point that ''if'' a frog was loose in space, it could be trapped in the gravity well of another planet and end up there rather than Earth. The 'theory', in the way it is expressed, contains the hidden implication that frogs ''start off'' floating around freely - not on any planet.

&lt;br /&gt;
Hmm.. How about frogs taken to the ISS for experimental purposes? Surely there's one or two if those? [[Special:Contributions/2A00:23C8:253C:101:5BC5:789F:56FB:A042|2A00:23C8:253C:101:5BC5:789F:56FB:A042]] 08:42, 17 December 2025 (UTC)&lt;br /&gt;
:From a general relativity point of view the ISS is not really different from the surface of Earth. In fact if you factor in the Jumping Frog Radius you can redefine the surface of Earth as englobing the orbit of the ISS, as, basically, the &amp;quot;surface of the Earth&amp;quot; is just some stuff jumbled together by gravity, so this technically applies to the ISS as well. [[Special:Contributions/78.241.48.142|78.241.48.142]] 11:06, 17 December 2025 (UTC)&lt;br /&gt;
:The ISS isn't in a constant frame of reference to the Earth's surface. If you want to redefine the surface of the Earth as being the &amp;quot;spherical ISS-like sphere&amp;quot; then that's a different body (loosely akin to the differences between analysing static and rotating black holes, for schwarzschild radius purposes). &lt;br /&gt;
:In fact, you have to do most of the work to ''get to'' ISS's orbit (far more than 'merely' getting to its altitude), 9.4km/s (ish). You only need about ~1.7km/s more to escape Earth entirely.&lt;br /&gt;
:Not quite within Champion Frog reach, of course. Or not a ''single'' CJF, but by using a lot of them, and by careful configuration of a stack of those frogs using the &amp;lt;s&amp;gt;Rocket&amp;lt;/s&amp;gt;Frog Equation, you could probably get at least one small frog to entirely leave Earth's gravitational influence. As you might from Earth, but you'd need a ''lot'' more frogs. [[Special:Contributions/82.132.238.175|82.132.238.175]] 11:59, 17 December 2025 (UTC)&lt;br /&gt;
::You also all forget that without boosts using fuel the ISS will end up back on the surface of the Earth with the frogs (burning up in the process but the relics would be on Earth again). And it is not said that any frogs could not be outside of Earth but they would be within the rjf radius, and thus be on their way back to this surface, as is the ISS. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 19:59, 17 December 2025 (UTC)&lt;br /&gt;
:::And if someone's using a 'frog stack', from the ISS, then the initial lower-stack-hop (and the quick return of the stage-1 frog(s) once the stage-2 one(s) hop, and so on, at least until they start drifting past it instead) will probably initiate an even sooner deorbit of the ISS.

Are the escape velocity figures in that table...even remotely accurate? For instance, the table claims Eris's escape velocity is 4.43 meters per second, while Wikipedia says 1.38 ''kilometers'' per second. (Also that Eris is ~4.43 orders of magnitude brighter than its moon, Dysnomia, in infrared. Hopefully that's unrelated.)

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic follows [[Cueball]], [[Megan]], [[Knit Cap]] and [[Ponytail]] as their beliefs evolve widely from a conventional car-first view of urban planning, then questioning the wisdom of car-centered policies, then favoring pedestrian-centered design, and finally wanting to discourage driving with tactics as extreme as road spikes. &lt;br /&gt;
&lt;br /&gt;
As a clever form of satire, the comic has twin aims:&lt;br /&gt;
# Present a progressive argument leading to a logical conclusion that's humorously radical, likely mirroring Randall's own evolution&lt;br /&gt;
# Satirize the irony of US policy discussions that elevate theory and feeling over actual best practices used in other countries.&lt;br /&gt;
&lt;br /&gt;
The '''first two panels''' present the conventional view.&lt;br /&gt;
&lt;br /&gt;
* First, Cueball and Megan complain about the common problem many car-centric cities face about not having enough space for all the cars, and they give a conventional suggestion of making more space for cars. &lt;br /&gt;
&lt;br /&gt;
* Next, Knit Cap mentions how she is going to visit {{w|Amsterdam}}, a city known for its {{w|walkability}} and bike friendliness, which gives Ponytail a chance to share the conventional concern that road cycling is bothersome to drivers. &lt;br /&gt;
&lt;br /&gt;
* This is the only moment that anyone pays any attention to Knit Cap; later when she has lived experience of the topic, they ignore her.&lt;br /&gt;
&lt;br /&gt;
In the '''third and fourth panels''', Cueball and Megan begin to evolve their thinking, wishing for better transit and more bike paths – another shortage common in car-centric cities – with Megan noticing that optimizing for drivers discourages pedestrians, which in turn spurs more driving – later calling it &amp;quot;a vicious cycle.&amp;quot;&lt;br /&gt;
* Megan's comments could relate to {{w|Induced demand}}, an economic theory in which increasing the supply of a scarce good or service causes the demand to rise faster than the increased supply, worsening the shortage. Traffic is a common example: when US cities try to widen roads and highways, they also incentivize even more vehicles and more driving, worsening the traffic problem. Conversely, other cities have tried removing traffic lanes or converting them to dedicated public transit lanes, and have reported a reduction in traffic congestion, due to people choosing other transportation options. Among urban planners, this is known as the {{w|Downs–Thomson paradox}}.&lt;br /&gt;
&lt;br /&gt;
In the '''fifth panel''' – taking place a week or two later – Knit Cap is back from her work trip to report that Amsterdam is really neat.&lt;br /&gt;
&lt;br /&gt;
In the '''sixth panel'''  Cueball's questioning turns into anger at car culture, beginning his full 180 from his previous, conventional car-centric view as he adopts a strong pedestrian-centric perspective.&lt;br /&gt;
* Cities face a dilemma of how to allocate limited street space. Car-centric cities allocate much more public land to vehicle storage and movement, leaving less space for bikes, pedestrians, dedicated transit corridors, greenspace, and density. &lt;br /&gt;
&lt;br /&gt;
In the '''seventh panel''', Megan takes issue with a particular type of vehicle – &amp;quot;those giant trucks&amp;quot; – and their threat to kids. All cars have blind spots in the front, and large trucks have blind spots sizable enough for the truck driver to be unable to see a standing child right in front.&lt;br /&gt;
* &amp;quot;Those giant trucks&amp;quot; likely refers to large pickup trucks, though she might be singling out lifted pickup trucks (raised after purchase), large tractor trailer cabs, or garbage/construction-style trucks.&lt;br /&gt;
&lt;br /&gt;
In the '''eighth panel''', Knit Cap's relevant personal observations gets ignored and interrupted by the armchair theorists – a subtle nod to how US policy debates often ignore successful examples from other developed countries. &lt;br /&gt;
* As Winston Churchill once said, “You can always count on the Americans to do the right thing after they have tried everything else.”&lt;br /&gt;
&lt;br /&gt;
In '''panels nine, ten, and eleven''', everyone's emotions peak with views that reach their zenith. Car culture is systemic! Driver-centric road planning is a vicious cycle! NETHERLANDS!&lt;br /&gt;
&lt;br /&gt;
By the '''final two panels''', Cueball's and Megan's evolution is complete. Desperate for any fix, Cueball concludes that city livability calls for making the driving experience worse, and then he suggests tire spikes as a solution. The final joke is that Megan actually supports the tire spikes idea, and that this extreme idea emerges from logical reasoning. &lt;br /&gt;
&lt;br /&gt;
Additionally, Cueball and Megan are coming up with crazy solutions while ironically ignoring Knit Cap's reasonable and practical lessons from how Amsterdam actually solves the problem. This continues the satire of US policy discussions that ignore real-world best practices because they come from across the Atlantic.&lt;br /&gt;
&lt;br /&gt;
* A reader who has been nodding along the whole time may reflect if they agree with Megan's final idea — and if not, why not? The whole comic is a type of logical argument in which many small steps of reasoning can lead to eventually extreme and satirical conclusions, similar to the famous {{w|A Modest Proposal}} by Jonathan Swift. It seems that Randall is sharing the evolution of his own views, while self-awarely noting that (1) if you take those views as far as they'll go, you can support some radical implications, and that (2) it's common for Americans to ignore success stories like Amsterdam's.&lt;br /&gt;
&lt;br /&gt;
The '''title text''' references a 1992 cyberpunk novel called &amp;quot;{{w|Snow Crash}}&amp;quot;, by Neal Stephenson. In the future of the novel, the roads are still dominated by motor vehicles, but a subculture of skateboarders exists which uses electromagnetic &amp;quot;harpoons&amp;quot; to attach themselves temporarily to cars. This allows the skateboarders to travel more quickly, by stealing a small amount of momentum from the vehicles. The suggestion here seems to be that such a system (despite being dangerous and chaotic) advantages other forms of transport, at the expense of cars, and is therefore at least somewhat beneficial. &lt;br /&gt;
&lt;br /&gt;
===What are the pros and cons of bike lanes?===&lt;br /&gt;
Protected bike lanes are safer compared to painted bike lanes, according to a [https://www.sciencedirect.com/science/article/pii/S2214140523001056 recent study]. It concluded that &amp;quot;protected bike lanes and buffered bike lanes had estimated protective effects on segments between intersections but estimated harmful effects at intersections. Conventional bike lanes had estimated harmful effects along segments and at intersections.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
From a wider perspective, however much you attempt to segregate different forms of transport (at junctions and other bottlenecks where space cannot be reserved), you'll always need to bring bicycles and traffic back into contact, briefly, and in circumstances where motorized traffic has become unused to sharing the roadspace with the lighter vehicles. This is unlike a more integrated place like Amsterdam where a driver is rarely going to be surprised by the presence of bicycles, overlook them and therefore cause an accident.&lt;br /&gt;
&lt;br /&gt;
=== What makes a city walkable? ===&lt;br /&gt;
To achieve a walkable area, urban planning (or zoning) must be seamlessly integrated with public transport planning. The central truth is that everybody is a pedestrian for some time, which also includes car drivers. Crucially, the average pedestrian is willing to walk about 2000 ft from their home to the next public transport stop, and an additional 2000 ft between the last public transport stop and their workplace. Opportunities for shopping and eating should exist at every connecting station, with the connections scheduled in a way that it both allows changing to the connecting train/tramway/bus immediately – as well as buying groceries.&lt;br /&gt;
&lt;br /&gt;
For an area to be walkable, at a minimum, all roads should have a sidewalk,{{Actual citation needed}} which, of course, costs area, but make the pedestrians' lives much easier and safer. But then, not only roads impact walkability. In the United States, many places open to the public are, by municipal ordinances, forced to provide enough parking space for [https://www.youtube.com/watch?v=OUNXFHpUhu8 all customers at any given time], which leads to serious knock-on effects: Pedestrians must often cross a large and weather-exposed parking lot in order to shop. A building can often be only re-purposed if a neighboring building is bulldozed to create the necessary parking area. And tenants who live in an apartment, but do not own a car, are forced to pay for the parking space they do not need. This creates difficulties, particularly in urban areas.&lt;br /&gt;
&lt;br /&gt;
Another topic is subsidizing public traffic. Municipalities in Switzerland, for example, order bus connections – e.g. a hourly bus from 6 AM until 10 PM, and in exchange, they cover the deficit of any such connection. That way, families, who usually are better taxpayers, move to villages, and beginning with grade 5, 6 or 7, pupils can still easily commute to a district school.&lt;br /&gt;

Outside the USA, they don't use this standard; not only do they have different parties in different countries, other countries' liberal and conservative parties tend to reverse that standard.&lt;/p&gt;
&lt;hr /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In another election-themed comic (this one posted the day after the {{w|United States presidential election, 2012|2012 U.S. presidential election}} November 7, 2012)—(see also [[1122: Electoral Precedent]], [[500: Election]], [[1127: Congress]], and [[1130: Poll Watching]])—this comic shows a bar graph representing expected (see note below) {{w|Electoral College (United States)|electoral college}} votes in the election, including a dotted line indicating the 270 electoral votes needed to win, a span of projections (&amp;quot;Forecast&amp;quot;), and the actual result.&lt;br /&gt;
&lt;br /&gt;
The forecast range is to the right of the 270 line, showing that the ''blue candidate'' {{w|Barack Obama|Obama}} (the {{W|Democratic Party (United States)|Democratic candidate}} is the ''blue candidate'' and the {{W|Republican Party (United States)|Republican candidate}} is the ''red candidate'' according to a convention used in the USA since the 2000 presidential election) was always projected to win by statisticians like [[Nate Silver]] and others. The only question among these people was by how much he was going to win. (The Electoral College votes are expectations until each state's voting results are announced early in November, and the electors actually vote in December and may change the situation somewhat.)  Randall is attempting to use this particular election to imply that polling data accurately indicates the likely outcome of a presidential election.  However, the close match between prediction and result in this one election could be a coincidence; the outcome of U.S. presidential elections frequently differs from projections.  Notably, in 1948, the Chicago Tribune printed a headline which turned out to be false and in 2016, polling data indicated that Clinton would defeat Trump.&lt;br /&gt;
&lt;br /&gt;
By contrast, most of the media was calling the election too close to call, with some news outlets actually projecting a {{w|Mitt Romney}} win. Essentially the large number of Republican {{w|pundit}}s who helped increase the pressures of right wing self-referencing media denial, the tendency of media to give any issue at least two dramatically or fictionally equal voices (for supposed &amp;quot;fairness&amp;quot;) regardless of the relative merits of the two sides, and the desire to present the election as a suspenseful &amp;quot;horse race&amp;quot; resulted in a lot of ''talking heads'' (i.e. pundits) disbelieving the polls. These factors shaped the &amp;quot;too close to call&amp;quot; narrative, leading to the punch line of this story:&lt;br /&gt;
&lt;br /&gt;
[[154|You don't need to believe in science or statistics for it to effectively describe or predict reality.]] The progressively more radicalized elements of this era are known for disregarding scientific or statistical consensus which reflects reality but does not conform to their world view. However, many of them were correct in their belief (in defiance of statistical data to the contrary) that Donald Trump would be elected in 2016.&lt;br /&gt;
&lt;br /&gt;
For those unfamiliar with the {{w|United States presidential election|US Presidential electoral process}}: Unlike other political offices, the election for president is not a direct election. Instead, each state is apportioned a certain number of &amp;quot;Electoral College&amp;quot; votes based on the number of House of Representatives seats (which is based on population) and Senate seats. For the most part (and there is perennial discussion on whether this should be changed) the candidate that receives the most popular votes in a given state receives all the Electoral College votes for that state. With 538 electoral votes total, receiving 270 Electoral College votes ((half of 538) + 1) is sufficient to be declared president-elect. For this reason, sometimes one candidate actually receive more popular votes (more people voted for the candidate) but have fewer Electoral College votes. This happened three times in the nineteenth century with elections of {{w|United States presidential election, 1824|John Quincy Adams in 1824}}, {{w|United States presidential election, 1876|Rutherford B. Hayes in 1876}} and {{w|United States presidential election, 1888|Benjamin Harrison in 1888}}. Then it did not happen again until the election of {{w|United States presidential election, 2000|George W. Bush in 2000}} and {{w|United States presidential election, 2016|Donald Trump in 2016}}.&lt;br /&gt;
&lt;br /&gt;
The title text is a subversion of what everyone else was saying at that time: that the election was unpredictable. Pundits often declare events to be &amp;quot;too close to call&amp;quot; when poll results are remarkably close; Randall is saying that the only thing that is &amp;quot;too close to call&amp;quot; is the difference between the results and the predicted results, as the outcome is all but certain.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created BY A CAR WITH AN ICBM. Don't remove this notice too soon.}}&lt;br /&gt;
This comic demonstrates one reason why vehicles have gotten progressively larger and more powerful, due to a type of {{w|arms race}}. When vehicles of different sizes share the road, passengers in the smaller ones will usually be more at risk in collisions. They have less momentum, and the body construction material provides less protection. So for safety reasons, people have incentive to buy larger cars.&lt;br /&gt;
&lt;br /&gt;
In the &amp;quot;Soon&amp;quot; panel, Randall has extrapolated this to adding offensive weaponry to large cars, and other drivers will need to do the same to compete on the road.&lt;br /&gt;
&lt;br /&gt;
The title text views this from the opposite perspective. The owner of a large car is worried that they'll kill people in small cars, so they shouldn't drive on the road at all. But the suggestion that they should drive on sidewalks is even worse, as it would put many pedestrians in danger. This is obviously absurd, but many people suggest that bikes should do the same for their own safety. Forcing bicycles to drive on the sidewalk is the best way to keep cyclists safe if we are not allowed to inconvenience drivers.&lt;br /&gt;

: The spin direction of whirlpools and basins is 'not' determined by the coriolis effect, on this scale its impact is way too small to make a difference.

If the baby is born 9 months BEFORE they're conceived, would that account for the shift in seasons for the southern hemisphere?

The events described during which the conception of a person with a given birth month occurred assumes that the parents were in the United States at that time.

The expected conception column is off, therefore the explanations may be off. Length of a human pregnancy is 38 weeks after conception, or 9 1/2 months, not the 9 months that is commonly portrayed.

:V-E day is not celebrated in the U.S. It has far less historical significance to us, since to us it was just an important date in the middle of a war. So the holidays that were included (like July 4 and October 31) make more sense in the U.S. for conception dates, even if they mean nothing internationally.

&lt;br /&gt;
== Gestation period ==&lt;br /&gt;
&lt;br /&gt;
The accepted length of a pregnancy in the U.S. is 38 weeks, but this is not true everywhere. In France, for instance, the term is 41 weeks. Both of these are just traditional and not based on precise data. A good study to look to here is Jukic, Baird, Weinberg, McConnaughey, and Wilcox &amp;quot;Length of human pregnancy and contributors to its natural variation.&amp;quot; This study is a very belated 2010 follow-up on a 1985 study on the rate of early pregnancy loss by Wilcox et al. They recruited women who had just ceased birth control because they intended to become pregnant. Although the study doesn't specify, they presumably had sex almost ever night, and according to the follow-up, urine samples were collected EVERY MORNING. These samples were tested for the presence of human chorionic gonadotropin (hCG), and if it was present above the threshold, the women were determined to be pregnant. Not much analysis was done on the question of how long after implantation it takes for hCG levels to rise above that threshold, but my tiny modicum of biological understanding suggests it should be hardly any time at all. The original study used this early-pregnancy data to measure the rate of loss of the fetus very early in pregnancy, controversially finding it to be around 30%.&lt;br /&gt;
&lt;br /&gt;
The follow-up had a different goal. It re-contacted those same women and managed to recruit most (though not all) into a new survey. The goal was to determine which of these women had artificially shortened their pregnancies through cesarean sections or other methods in order to exclude them from the analysis (with measures taken to account for the biases this introduces). The women who were not excluded numbered 120 and had a (corrected) median gestational time (from ovulation to birth) of 38 weeks 2 days. But what is more interesting is that even after excluding premature outliers, this sample of 120 women had a range of 37 days. That means the earliest non-excluded birth was 37 days before the latest birth.&lt;br /&gt;
&lt;br /&gt;
I think this explains why there is so much variation in how different countries treat births and why we never get a precise figure. Even within a single population of women (I think from around North Carolina? They don't say), the range of outcomes is enormous. Still, I think this is strong evidence that the average gestational period is closer to 38 weeks than to 40 weeks (or 41, as the French would have it). But at any rate, I imagine the magic number Randall had in mind was 9 months, figured as 3/4 of a year (i.e. about 274 days, or 39 weeks 1 day).

:&amp;quot;Gen-ed&amp;quot; is general education.  It probably refers to classes that satisfy the &amp;quot;core requirements&amp;quot; that everyone graduating from the institution must pass, regardless of major.  Typically these will include English composition (basically, how to write a paper), some first- and maybe second-year humanities classes, some first- and maybe second-year science or engineering classes, and some first- and maybe second-year math.  These days, many US students graduate high school with college credit for some of these classes through dual-enrollment classes, Advanced Placement classes (and the required test), or similar programs (it's not unheard of to start university as a &amp;quot;third year student&amp;quot; - or &amp;quot;Junior&amp;quot; in US education lingo).  &amp;quot;400&amp;quot; means 4th-year classes (individual classes will be numbered 401, 402, etc.), which are typically only available to students majoring in that topic or a related topic.  Fun fact:  In some graduate schools, students are allowed to take a limited number of &amp;quot;400&amp;quot; classes to meet their graduate degree requirements.

::From a UK perspective, in this course scheme are we talking about &amp;quot;college&amp;quot; (Further Education, next level up from Secondary, variously known as Tertiary or &amp;quot;6th Form&amp;quot; in some cases) rather than &amp;quot;university&amp;quot; (Higher Education)?&lt;br /&gt;
::University 'academic careers', UKwise, are probably somewhat flexible (gap/sandwich years, leave of absence for personal reasons, etc), but I don't know of anyone who just 'kept reattending' to add more things. (I, myself, changed department, mid-way, but it was in context of which sub-part of the university was the primary focus of my already established multidiscaplinary Combined Science degree, and didn't change the effective year-group or classes I attended.) Also, I don't think we had &amp;quot;Underwater Basket-Weaving 101&amp;quot;-type optional/compulsary parallel prerequesit courses as 'minors', just automatically scheduled in sub-subject intro lectures for (e.g.) the specific applied-physics types of maths that the physics course used, to drag us up from the A-Level/HND/whatever proficiency that we'd previously gained to qualify us for our offered university place.&lt;br /&gt;
::College (Tertiary/6th Form/etc, optional followup to the compulsary Secondary-level education) was basically two years of whatever schedule you were willing and able to pack together from the offered courses... possibly could extend to three years (I had that option with a subject not taught at Secondary level... one-year of the Secondary course, then do the two-year Tertiary-level one starting in the second year of my other Tertiary-level subjects, but I abbreviated it) if it needed to be. Together with those completely resitting failed subjects, and those (mostly adult-education) signing up for a 'post-education education' as much as their time of life (and funding) allowed, no doubt there'd be opportunity to be nigh on an 'eternal student'. But you don't &amp;quot;Graduate&amp;quot; that level of education, in the UK. You might pass a course or two (or more, I personally had five separate qualifications on the go at the same time, though just the three 'main' ones) but it's not 'packaged' like undergrad university attendance.&lt;br /&gt;
::At least it wasn't for me. Maybe things have changed. They're apparently having end-of-year Proms all across the various school-year cohorts, these days, as an imported concept from the US. The most I ever had (not that I'm complaining, though I was never a good dancer) was the Christmas Disco. After the last School Assembly of the year (attendance awards and sporting triumphs may be noted and feted, but all prior to any actual exam results known) were a few days of &amp;quot;getting ready for Summer&amp;quot; with possibly a very much relaxed tailed-off 'curriculum' and being allowed to bring in board games on ''the'' last day of the school year (for those not bunking off entirely). Then... see you September! (Or not, if moving on to the &amp;quot;next school&amp;quot; or maybe that first proper full-time job as an adult.)

:::American here who went to college (university) in the US who has raised kids in the UK and just sent the last one off to university. We don't narrow down our studies in the States like in the UK. In most places (there are exceptions) all the way through to the end of high school (12th grade/year 13) we're still taking Math, English, some sort of History/Geography, and some science classes. Maybe even P.E. Then when you go to university, you don't necessarily have to declare a major. In the UK, you have already spent the last two years just focused on 3-4 subjects for A-levels (or B-tech?), (everyone across the country takes the same exams at the exact same time) and when you leave for uni it might be just one subject. I was shocked when I found out that my husband's degree in Math(s) meant that he only took classes related to that! Because we don't narrow things down, and because we don't have the same level of standardization in testing as the UK, the US approach of general studies fits with our overall education model. It does take most people 4 years to complete a degree as opposed to the UK's 3, but our GenEd courses at university aren't the equivalelent of UK college (which you can start at 16) or A-levels.

I think &amp;quot;speedrun University&amp;quot; can also implies someone trying to finish university ahead time interval (4 years, usually). I know people who have enough AP credits and do enough over-loading and summer classes trying to finish university within 2 years (the minimum time required to get a degree for most university). On the other hand, I believe this comic hint the people trying to complete all major's requirement inside the University to get &amp;quot;100% achievement&amp;quot;. Most of university do not allow anything above double-count (count one class for more then 2 major requirements). If the people in comic have complete more then 20 major requirement within 15 years, that translate to the people have take enough class to complete at least 10 major's class/graduation requirements under the no triple count rule. in average, complete 1 major per 1.5 years, which in some sense, is amazing, also count as &amp;quot;speed-run&amp;quot;. --(Someone recently been bitten by University's major tracking sheets) [[Special:Contributions/130.215.10.247|130.215.10.247]] 14:41, 30 September 2025 (UTC)&lt;br /&gt;

The &amp;quot;eternal student&amp;quot; was a thing when I went to college (&amp;quot;uni&amp;quot; for our UK friends) because tuition was nominal at most state affiliated universities.  The optimal path if your parents weren't giving your money was to get a job as a Resident Advisor in one of the dormitories where most first year students lived as that would cover your room and board.  Most school have responded to this by instituting some sort of cap on the number of courses and years you could take before they would force you to graduate.  The dedicated eternal student would then apply to graduate school. {{unsigned ip|2600:1700:b39:3010:70ea:4d8d:1888:b6b8|18:17, 3 October 2025 (UTC)}}&lt;br /&gt;

Is it true that, as asserted, most students finish the gen-ed courses in their first year or even first term?  In my B.Sc. program, first-year students were expected to take 3 full-year credits of sciences, 2 half-credits in math (1 per term), and 1 full-year arts credit.  A second credit of arts was required to complete the degree requirements, but that was generally taken in a later year.  I did things a bit differently: 2 full credits in math in my first year along with the 3 science credits, and I did my arts requirements in my 3rd and 4th years.

Maybe this is a nitpick, but I don't like how this explanation conflates 100% speedruns and getting all achievements. What &amp;quot;100%&amp;quot; means varies from game to game, but it's generally unrelated to external &amp;quot;achievement&amp;quot; trackers. It's quite common for achievements to be awarded for things the community considers irrelevant to finishing the game, such as failing under particularly silly circumstances or winning the game while deliberately avoiding certain mechanics; there might even be achievements which are incompatible and must be achieved in separate runs! &amp;quot;100%&amp;quot; != &amp;quot;all achievements,&amp;quot; usually.

#Edward Tufte on Pie Charts&lt;br /&gt;
Maybe we should also mention what the dodfather of visualization has to say on pie charts:&lt;br /&gt;
Edward Tufte gives the pie chart a more succinct and decisive treatment in &amp;quot;The Visual Display of Quantitative Information&amp;quot;:&lt;br /&gt;
''A table is nearly always better than a dumb pie chart; the only worse design than a pie chart is several of them, for then the viewer is asked to compare quantities located in  spatial disarray both within and between charts [...] Given their low density and failure to order numbers along a visual dimension, pie charts should never be used.'' (Tufte: &amp;quot;The Visual Display of Quantitative Information&amp;quot;, quoted by https://news.ycombinator.com/item?id=2991062 )&lt;br /&gt;

(previous editor did not sign) My favourite missapplied chart is a doughnut chart (which is a piechart without of the center comes from one of Germanys big automobile clubs. They made a campaign about how dangerous it is to use a phone in the car, and part of it was a statistic wher ethey would find out, at various places (red light, motorway, city trafic or country roads) what percentage of people would use their cell phone. They summarized it in a doughnut chart which does not make any sense: https://www.mobil.org/wp-content/uploads/2016/08/%C3%9Cbersicht-Verkehrsz%C3%A4hlung-2016-Mobil-in-Deutschland-e.V-1-724x1024.jpg [[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 16:29, 14 August 2018 (UTC)&lt;br /&gt;
:It took me a while to figure this one out. I kept thinking it was representing data on two axes, like some sort of combined pie chart/polar area diagram. Like a spie chart, but working in some different, unfathomable way. But no, the radial dimension means nothing, it's just used to help clarify the borders. They took a bunch of percentages of different groups, then put them together in a bar chart, decided they didn't like how the bars looked, and told Excel to turn it into a pie chart. So it added the percentages to get a total, then divided each data point by that, and used the results to make a completely meaningless pie. It's like discovering that skim milk is 0.5% fat, whole milk is 3.5%, and cream is 36% fat: adding them up gives 40, so you make a pie chart where skim milk is 1/80 of a circle, whole milk is 7/80, and cream is 72/80.

In Emily Wilson's translation of the Odyssey (paperback edition), she writes that Odysseus says, &amp;quot;My name is Noman. / My family and friends call me Noman&amp;quot; (9.366-367). So given that the comic is about Emily Wilson's translation, shouldn't the title text say, &amp;quot;Noman was home,&amp;quot; not &amp;quot;Nobody was home&amp;quot;?

:The trouble with that is the Macbeth/Witch-King thing whereby &amp;quot;no man&amp;quot; (of woman born, in the case of the former) is said to be able to defeat them, only for a caesarian-delivered individual to get the chance to overcome the resulting hubris in the former case and a tag-team of hobbit and woman (and arguments about which was most important!) in the latter. &amp;quot;No man&amp;quot; has baggage.

Not why the explanation suggests that buying more books than you read only happens because 'technology and marketing slowly addicts us'.

		<summary type="html">&lt;p&gt;GreatWyrmGold: I wanted to follow the instructions, but I wound up making other changes. I am not actually certain that these two comics constitute a series, but I don't want to say that in the body of the &amp;quot;article&amp;quot;...&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;&amp;lt;noinclude&amp;gt;{{Incomplete|Remove bullet points}}&amp;lt;/noinclude&amp;gt;&lt;br /&gt;
At the beginning of 2025 [[Randall]] made a comic, [[3037: Radon]], where [[Ponytail]] inspects [[Cueball|Cueball's]] house and finds problems with it, using a small hand held device. The problems, however, relates to the planet the house is build on, and not the building it self. Two months later the same happens again in [[3059: Water Damage]], completely the same setting, thus establishing these two comics as a series.&lt;br /&gt;
&lt;br /&gt;
Only time will tell if this will be an ongoing series, or stop with just those two. But given that the settings and the device and the joke is along the same lines, it is likely that these two comics constitute a series.&lt;br /&gt;
&lt;br /&gt;
This would be the first new [[:Category:Comic series|series]] since [[:Category:Cursed Connectors|Cursed Connectors]] which began in 2021, and the first where the two comics follow each other like an actual series since [[:Category:Alien Visitors|Alien Visitors]] which came out a bit earlier in 2021.&lt;br /&gt;
&lt;br /&gt;
Shortly after this series was started another comic, [[3070: Orogeny]], followed with a similar look on geology as part of house buying. Although that comic is reminiscent of the other two, there is no home to inspect, thus it cannot be part of this series.&lt;br /&gt;
&lt;br /&gt;
The comic [[3051: Hardwood]] is also playing with these ideas, but that one is without Ponytail.&lt;br /&gt;
&lt;br /&gt;
However, if Randall continues this kind of comic, then maybe there should be another category for the entire portfolio of such comics. In that case, this series will be a sub category of the larger series series, since the two inspection comics are arguably a connected series in their own right.&lt;br /&gt;

| titletext = Wavefunction collapse is only one interpretation. Under some interpretations, graduate students also have souls.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created BY  A SOUlFUl PARTICLE DETECTOR. Should the reference to unsolved problem be removed? Those comics are very different to this and the other two mentioned as it is three different things not three replies to one question. And cursed is not the same a wrong or chaotic!}}&lt;br /&gt;
&lt;br /&gt;
This comic presents three possible responses to a common question posed by undergraduates upon confronting the {{w|Measurement problem|problem of measurement}} in quantum mechanics - does the apparently privileged role of subjective or conscious {{w|Observer (quantum physics)|observers}} in wavefunction collapse imply that human consciousness itself impacts physics? This question is sometimes phrased as: does the observation effect or quantum collapse prove humans have souls? These questions stem from a misunderstanding of what an &amp;quot;observer&amp;quot; in physics really is, a misunderstanding the comic depicts with a college student asking his professor about human consciousness.&lt;br /&gt;
&lt;br /&gt;
The 'Bad' option shows Cueball telling his student that everybody has a soul, and their individual consciousness affects reality in some way. The 'good' option shows Cueball telling his student that consciousness doesn't play a role at all, and that it is 'just a physical measurement'. The 'chaotic' option shows Cueball apparently observing that the wave function collapses only when ''he'' looks at it, because he is special in some way (in this case, Cueball is a professor while Hairy is the undergraduate student).&lt;br /&gt;
&lt;br /&gt;
That quantum states exist as probability density distributions, but are only ever observed in definite states, raises the question of how the quantum world transitions into the classical world. The (historically) most popular {{w|Copenhagen interpretation|interpretation}} posits that {{w|wave function collapse}} occurs upon the measurement of a quantum state, in which the multiple mathematically possible states resolve into a definite state, without explicitly defining precisely when this &amp;quot;collapse&amp;quot; occurs, or what defines &amp;quot;measurement;&amp;quot; in fact, when measuring, say, an electron in a superposition of two states, wavefunction collapse could occur at any stage from the electron interacting with the detector, to the detector recording the measurement, to the scientist observing the recording. A famous though experiment, {{w|Schrödinger's cat}}, takes this to the extreme: if a cat is placed a box with a decaying radioisotope that upon decay triggers a gas bomb that kills the cat, shouldn't this place the cat-bomb-isotope-box system into a mixed state that only undergoes wavefunction collapse upon opening and observing whether the cat is alive or dead? The Copenhagen interpretation is agnostic to this question, only confirming that the cat will have resolved into its alive or dead state at or before observation. The {{w|Consciousness causes collapse}} postulate endorsed by the &amp;quot;bad&amp;quot; panel -- unfashionable now, but taken seriously historically -- posits that the conscious observation is indeed what triggers wave-function collapse. The 'good' panel, rather flippantly, seems to endorse a more modern {{w|Quantum decoherence|decoherence}}-based interpretation - that every interaction inside the cat-box system is a &amp;quot;measurement&amp;quot; that destroys the superposition well before the human observer enters the picture. Finally, the `chaotic` option is far more radical and sollipsistic than the `bad` - it's not merely conscious observation that causes collapse, but PhD-holding and tenured consciousness. &lt;br /&gt;
&lt;br /&gt;
Good, bad, and chaotic are likely references to the {{w|Alignment (Dungeons &amp;amp; Dragons)|alignment system}} in the role-playing game {{w|Dungeons &amp;amp; Dragons}}. In D&amp;amp;D, roles are characterized by their morality (good/neutral/evil) and their views about order (lawful/neutral/chaotic).&lt;br /&gt;
&lt;br /&gt;
The title text continues the chaotic option.  Graduate students are intermediate between undergraduate and professors.  It is unclear whether graduate students can cause waveform collapse, and therefore have souls.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Hairy is sitting behind a desk with one a hand on the desktop and the other in his lap. He is looking up at Cueball, who is standing in front of the desk. Hairy is asking a question:]&lt;br /&gt;
:Hairy: If the wavefunction only collapses when I observe it, does that mean my consciousness affects the universe?&lt;br /&gt;
&lt;br /&gt;
:[Three panels follows showing three possible responses from Cueball. Each panel has a label above, written inside a small rectangle that is overlaid on the top left of each panel. Each panel shows the same zoom in on the top half of Cueball.]&lt;br /&gt;
&lt;br /&gt;
:[Panel 1]&lt;br /&gt;
:Bad:&lt;br /&gt;
:Cueball: Yes. Quantum entanglement proves that we all have souls.&lt;br /&gt;
&lt;br /&gt;
:[Panel 2]&lt;br /&gt;
:Good:&lt;br /&gt;
:Cueball: No. Consciousness plays no role here. Its just physical measurement.&lt;br /&gt;
&lt;br /&gt;
:[Panel 3]&lt;br /&gt;
:Chaotic:&lt;br /&gt;
:Cueball: No. The wave function collapses when '''''I''''' look at it because I'm a full professor.&lt;br /&gt;

As of right now, Randall has got his wish: the page is protected. Unfortunately, it's protected with &amp;quot;yachts&amp;quot; on it and, of course, it can't be reverted because of the protection. [[User:Jeremyp|Jeremyp]] ([[User talk:Jeremyp|talk]]) 10:45, 14 March 2019 (UTC)&lt;br /&gt;

It is disappointing that xkcd readers think it's funny to vandalize the wikipedia article because of this comic. I highly doubt that Randall himself did so, and I don't think he intended for anyone else to actually vandalize it either. Furthermore, giving these viewers any satisfaction by actually including this info in the comic discussion seems somehow inappropriate.

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1007&lt;br /&gt;
| date      = January 23, 2012&lt;br /&gt;
| title     = Sustainable&lt;br /&gt;
| image     = sustainable.png&lt;br /&gt;
| titletext = Though 100 years is longer than a lot of our resources.&lt;br /&gt;
}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
This is a simple scatterplot showing how often the word &amp;quot;sustainable&amp;quot; has been used in English texts in the US each year. As can be seen, the y-axis is given a logarithmic scale, meaning that the apparently linear trend is actually exponential. [[Randall]] [[605: Extrapolating|humorously attempts to extend the graph]] to the point the frequency exceeds 100% about a century from now, which is obviously impossible (hence the quip that the word's usage is itself &amp;quot;unsustainable&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
The use of the word &amp;quot;sustainable&amp;quot; has been increasing as people become more aware of the steadily increasing use of nonrenewable resources and need to ensure that the Earth's resources do not become totally exhausted, through sustainable development. {{w|Sustainable development}} refers to the practice of using resources that simultaneously aims to meet human needs while preserving the environment so that these needs can be met not only in the present time, but also for generations to come.&lt;br /&gt;
&lt;br /&gt;
More realistically, the actual use of &amp;quot;sustainable&amp;quot; is likely to be logistic rather than exponential growth. A logistic curve (not to be confused with &amp;quot;logarithmic&amp;quot;) describes a trend that at first appears to behave exponentially, but then tapers off and reaches a cap, as it is actually a curve leading up to an arbitrary mid-point 'origin' part way through the track and then levels back off again (in a doubly-reflected manner, typically) to reach a new plateau. This is demonstrated by the [https://books.google.com/ngrams/graph?content=sustainable&amp;amp;year_start=1940&amp;amp;year_end=2022&amp;amp;corpus=en&amp;amp;smoothing=0&amp;amp;case_insensitive=false Google ngrams graph of word usage for &amp;quot;sustainable&amp;quot;]. Logistic growth is commonly used to model data that naturally increases exponentially but has a limiting factor, which in this case is the meaningfulness of text consisting entirely or mostly of a single word. Until we actually reach the logistic midpoint (''possibly'' at 50% usage, but very much depending upon other confounding factors and likely somewhat less in this actual case) the data might indeed look like they fit a log-plotted exponential curve.&lt;br /&gt;
&lt;br /&gt;
As Randall somewhat depressingly mentions in the title text, the ~100 years that it will supposedly take for the word &amp;quot;sustainable&amp;quot; to become unsustainable is actually a lot longer than most of our nonrenewable resources will last on the Earth. The idea that ''all'' of the Earth's coal, oil, natural gas, etc. that has built up over the past millions of years may be completely gone within the century is unsettling. This comic was used in the 2018 book ''[https://books.google.ca/books?id=J6grDwAAQBAJ&amp;amp;pg=PA128&amp;amp;lpg=PA128&amp;amp;dq=enlightenment+now+xkcd&amp;amp;source=bl&amp;amp;ots=8LvAVHQU2_&amp;amp;sig=ACfU3U27rxPWl4N8-muk1eRSm0BMMqWoHA&amp;amp;hl=en&amp;amp;sa=X&amp;amp;ved=2ahUKEwjOkIne-rTkAhUYs54KHRCZCHsQ6AEwEHoECAkQAQ#v=onepage&amp;amp;q=enlightenment%20now%20xkcd&amp;amp;f=false| Enlightenment Now: The Case for Reason, Science, Humanism, and Progress]'' by Steven Pinker as it discusses the concept of sustainable energy. &lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is another in a [[:Category:COVID-19|series of comics]] related to the {{w|COVID-19 pandemic}}. &lt;br /&gt;
&lt;br /&gt;
Ponytail, who was eager to see ''{{w|Wonder Woman 1984}}'', the 2019 sequel to the acclaimed 2017 ''{{w|Wonder Woman (2017 film)|Wonder Woman}}'' film, decided to block all news media leading up to the film, to avoid {{w|Spoiler (media)|spoilers}}. Avoiding spoilers is a common practice for people who do not wish to be &amp;quot;spoiled&amp;quot; by reading or hearing any plot points of the film, because they want to be immersed in the movie when watching it for the first time, by not being able to predict any plot twists before they occur. Many early reviewers may inadvertently give away key parts of the film, which may ruin the experience for some watchers, and story elements may be leaked by inside sources, either accidentally or deliberately.&lt;br /&gt;
&lt;br /&gt;
However, there have been many delays for release of the film, in part because of the [[:Category:COVID-19|COVID-19 pandemic]] in the spring of 2020. The film was originally delayed from November 1, 2019 to June 5, 2020 to allow more time for production, and then, after the pandemic struck, was pushed to August 14, 2020, then October 2, 2020, before it was finally moved to December 25, 2020. The film studio announced a simultaneous release of the film in theaters and also on streaming platform {{w|HBO Max}}.&lt;br /&gt;
&lt;br /&gt;
Absurdly, Ponytail apparently continued to block news sites after the delays, and so has not read ''any'' news in over a year, even news unrelated to movies. Because of this, she is apparently totally unaware of the entire pandemic, as well as more predictable major news items like the 2020 United States presidential election. This is particularly absurd, because these events were influential enough that it would be difficult or impossible to avoid awareness, even with no media exposure. They have been common topics of conversation, not to mention face-masks and other public health-control measures have now become ubiquitous, and election campaign signs and bumper stickers were common sights in the lead-up to November.&lt;br /&gt;
&lt;br /&gt;
How the release date being postponed (twice) did not convince Ponytail to find out why, therefore becoming aware of the pandemic with its associated lockdown and public health-control, is a question that is left unanswered. Her confusion as to why her movie is now being shown at a {{w|drive-in theater}} is a sign that she's unaware of COVID-19. Drive-in theaters have been seen as a safer option than indoor movie theaters during the pandemic. &lt;br /&gt;
&lt;br /&gt;
Cueball tries to warn her about the ongoing pandemic, but in an effort to avoid spoilers, she silences him. This may imply that in her wildly excessive effort to avoid spoilers, she's avoided leaving her home and talking to people, which could explain her exceptional level of disconnection from current events. Cueball then tells her to wear a mask, but she is still confused. Ponytail says that she will dress up in costume as Wonder Woman, who is traditionally shown wearing a {{w|tiara}} but not a mask (unlike Batman or many other comic characters, although [[2367: Masks|efficiency of their masks]] still varies wildly in regards to COVID-19 protection).&lt;br /&gt;
&lt;br /&gt;
The title text expands on Ponytail's speculation that the use of the drive-in theaters is a &amp;quot;retro promotion,&amp;quot; presumably because drive-ins and the '80s setting of the movie are now both considered to be retro in 2020. However, they are not associated with the same period; drive-in theaters in America had their heyday in the 1950s and '60s, and were in rapid decline by the '80s. Ponytail further demonstrates her misunderstanding of history by mentioning several other things which she wrongly believes are from the '80s. {{w|Britney Spears}} is a singer who was popular in the late 1990s and early 2000s. {{w|Hustle (dance)|The Hustle}} was a disco dance popular in the mid-1970s. {{w|Pogs}} under that name peaked in the mid-1990s.  {{w|Elvis}}'s appearance on the ''{{w|Ed Sullivan Show}}'' - a pivotal moment in American pop culture - occurred on September 9, 1956. (''The Ed Sullivan Show'' went off the air in 1971, Ed Sullivan died in 1974, and Elvis Presley died in 1977{{Citation needed}}.) This joke concerns the phenomenon of people lumping together all time periods before their birth, which results in &amp;quot;retro&amp;quot; or &amp;quot;period&amp;quot; representations combining elements from widely different time periods. (A similar behavior is seen in [[771: Period Speech]].) Cueball points this out by asking Ponytail when she was born, implying that, if she'd actually lived through any of those time periods, she'd realize that they were distinct. If Ponytail could not remember any of these events in her childhood, an age of about 20 years can be set as an approximate upper bound for this particular character's age.&lt;br /&gt;
&lt;br /&gt;
This comic is similar to [[2280: 2010 and 2020]] and [[2338: Faraday Tour]], which also involve characters who are unaware of the COVID-19 pandemic.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic takes three {{w|laser|laser-based}} technologies - laser eye surgery, laserjet printers, and laser hair removal - and conflates them, with humorous results. These are illustrated through reviews by users of the resulting combinations. For the original combinations, the reviews are highly positive. For the new combinations, most are negative, because most of these new &amp;quot;technologies&amp;quot; are ill-conceived and possibly harmful.&lt;br /&gt;
&lt;br /&gt;
'''{{w|Laser eye surgery}}''' gets a positive review, since it has successfully corrected the reviewer's vision, so that they no longer require glasses. There are a range of laser eye surgeries to correct near- and far-sightedness, as well as various other conditions. {{w|LASIK}}, one of the more common laser eye surgeries, works by using lasers to cut open the cornea and ablate a small amount of the lens.&lt;br /&gt;
&lt;br /&gt;
'''Laser eye removal''' would be very painful, and thus the review is negative, stating that the reviewer had read the description incorrectly, likely believing it to be one of the real combinations on the chart. The screams of pain expressed in the review have the humorous implication that the review is being typed directly after the ill-advised procedure, though this may just be an after-the-fact expression of the reviewer's feelings. If they produced the review without aid, this would probably have been made more difficult as a result of the surgery (unless only one eye was removed). At least in animal surgery, however,  laser eye removal [https://www.youtube.com/watch?v=smK0NYUtoqk does exist](WARNING: EXPLICIT/GRAPHIC CONTENT).&lt;br /&gt;
&lt;br /&gt;
'''Laser eye printer''' refers to printing on (or possibly ''of'') an eyeball, which only prompts a disgusted &amp;quot;Eww&amp;quot; response. Both probably can find their applications, either in adding images onto ones eyes or creating artificial eyes for implantation, but would probably be quite disgusting to operate for many people.&lt;br /&gt;
&lt;br /&gt;
'''Laser jet surgery''' could be performing maintenance on a jet with lasers, which would be potentially dangerous and error-prone.{{Citation needed}} Alternatively, it could mean laser surgery done on a human from a jet aircraft, using a laser mounted to it. The human being operated on could be aboard that aircraft, on another aircraft, or on land: in any case, it does not sound like a safe approach. Another interpretation is that it could refer to surgery using a jet made of lasers, which is even worse, as it would probably cause the entire body to be disintegrated.{{Citation needed}} Yet another interpretation is that the procedure would implant parts of a jet into one's body. The statement's ambiguity may contribute the reviewer's concern, or the reviewer could be nervous over the fact that it would be a very difficult and delicate procedure and trying it could easily go horribly wrong.&lt;br /&gt;
&lt;br /&gt;
'''Laser jet removal''' appears to be the destruction of jets with lasers, which apparently works, but angered the Federal Aviation Administration, and probably resulted in legal consequences for the reviewer. This could be a reference to [https://www.faa.gov/about/initiatives/lasers/ the real FAA concern] of the many incidents of [http://www.laserpointersafety.com/laser-hazards_aircraft/laser-hazards_aircraft.html people using laser pointers] against aircraft. [https://en.wikipedia.org/wiki/Laser_Weapon_System &amp;quot;Laser Jet Removal&amp;quot;] actually exists as a military weapon system, though it's primarily meant to be used against jet ''missiles'', rather than jet planes.&lt;br /&gt;
&lt;br /&gt;
'''LaserJet printer''' is a popular {{w|HP LaserJet|line of Hewlett Packard laser printers}}. {{w|Laser printing}} is a technology which uses a laser to electrically charge a drum so that it collects ink in the form of the image to be printed, before transferring it to paper. The printer seems to work well for the reviewer, as it has been given a positive review.&lt;br /&gt;
&lt;br /&gt;
'''Laser hair surgery''' turns out to be a fancy name for cutting hair with a laser -- an overengineered, and potentially dangerous, technique for achieving the same results that you could with clippers and scissors. It is rated neutrally, since it did the job, but the reviewer found the name confusing and they disliked the smell of burning hair.&lt;br /&gt;
&lt;br /&gt;
'''{{w|Laser hair removal}}''' is the process of destroying hair follicles with bursts of laser light to prevent the growth of unwanted hair. This appears to have been effective for the reviewer.&lt;br /&gt;
&lt;br /&gt;
'''Laser hair printer''' appears to be a bizarre printer that uses hair in place of paper, or perhaps as the construction material for a {{w|3D printing|3D printer}}. Unsurprisingly, this just creates disgusting messes of hair and keeps jamming the printer, resulting in a negative review. The title text extends this joke, giving some common printer error messages amended for the hair printer. A paper jam is when paper gets stuck in the workings of the printer, usually because it was creased, or more than one sheet fed in at once; in the hair printer this becomes a hair jam. An inkjet printer requires replaceable ink cartridges, and when the ink is used up this will usually result in an ink cartridge running low error; the hair printer appears to require cartridges of {{w|hair conditioner}}. As an additional twist, it uses color-safe conditioner, a product intended to prevent the washing out of dye from the users hair; here, it presumably protects the color of the printed image or item. Legal and Letter are {{w|Paper_size#North_American_paper_sizes|paper sizes}} used in North America; apparently, the same terms are used for standard supplies of hair for the hair printer. It is not clear what role lasers play in this process.&lt;br /&gt;
&lt;br /&gt;
Laser eye removal has been mentioned before, see the lower right part of the [[1619: Watson Medical Algorithm]] chart.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BOT RUNNING ON 3 INCHES OF THE UK - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic uses dimensional analysis to humorously describe the end of coal-powered energy production in the United Kingdom, in reference to the [https://www.bbc.co.uk/news/articles/c5y35qz73n8o shutting down of the Ratcliffe-on-Soar coal power plant] in central England on Monday, September 30, 2024. This event signified the closure of the last coal-fired power plant in the UK. This is an important milestone in the global energy use, because the United Kingdom was at the forefront of the {{w|Industrial Revolution}}, which began an era of large-scale coal extraction to fuel the world's industries. Over the course of the past several decades, coal has increasingly fallen out of favor, with natural gas becoming a more viable power source, and an increasing percentage of energy needs being met without the use of fossil fuels (from sources such as nuclear, hydro, solar and wind power). The fact that the UK has now fully transitioned away from the use of coal as a major energy source marks a major shift in how industrialized nations are powered.&lt;br /&gt;
&lt;br /&gt;
UK coal ''production'' has also been in decline significantly since {{w|1984–1985 United Kingdom miners' strike|the politically enforced decline in the 1980s}}, and the proposed opening of the new {{w|Woodhouse Colliery}} in Cumbria [https://www.bbc.co.uk/news/articles/c62533nyvzwo seems to have been stopped], leaving just the [https://www.gov.uk/government/statistics/coal-mining-production-and-manpower-returns-statistics-2023/coal-mining-production-and-manpower-returns-received-by-the-coal-authority-january-to-march-2023 remnants of the coal-mining industry] active. There remain uses for coal, both locally obtained and imported, but the conversion away from coal [https://www.bbc.co.uk/news/articles/c70zxjldqnxo in various industries] marks a possible soft-end to the British era which started with the {{w|Industrial Revolution}}.&lt;br /&gt;
&lt;br /&gt;
The equation shown in the comic determines how much coal was mined in the UK with respect to the surface area of the region, and calculates the height of it if the coal mined out was taken away in an even layer from ''all'' across the UK. It calculates, that the coal mining industry has lowered the surface of the United Kingdom by an average distance of 3 inches (about 7.6cm). In reality, coal is usually extracted from specific locations, creating {{w|Flash (lake)|localized subsidence}} of more depth above old underground-workings (or, where open-cast, visible quarrying scars that may have been partially relandscaped) and leaving other areas generally unaffected. &lt;br /&gt;
&lt;br /&gt;
''UK DESNZ'', referenced in the comic, is the United Kingdom's {{w|Department for Energy Security and Net Zero}}, the source for the statistic on UK total coal production from 1853 to present; see DESNZ's historical statistics of coal production [https://www.gov.uk/government/statistical-data-sets/historical-coal-data-coal-production-availability-and-consumption here].&lt;br /&gt;
&lt;br /&gt;
Since [[Randall]] is warning about [[:Category:Climate change|climate change]] in several of his comics, he likely sees this as an important step away from the use of fossil fuel.  &lt;br /&gt;
&lt;br /&gt;
The comic’s title text adds a similar, but even more ludicrous, metric for earth excavated for a rabbit warren. The volume of earth described, 0.1&amp;amp;#x202F;nm × 240,000&amp;amp;#x202F;km&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;, is equal to 24&amp;amp;#x202F;m&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;.  The text refers to {{w|Watership Down}}, a 1972 novel about a group of English rabbits. (A sole sequel to Watership Down, {{w|Tales from Watership Down}}, was published in 1996.) The text also refers to a former rabbit-run coal plant in the UK and claims that it was shut down in the 1990s. No actual {{w|Run, Rabbit, Run|rabbit-run}} coal plants have ever been documented.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[The following formula is shown (with the divisors below a horizontal line in the comic, rather than inside square brackets):]&lt;br /&gt;
:UK total coal production (1853-present, ''UK DESNZ'') / [(coal seam density) × (UK land area)] = 25 billion tonnes / [1.3kg/L × 240,000km²] ≈ 3 inches&lt;br /&gt;
:[Cueball is standing to the right of the formula, upon a dotted line representing the prior ground level. Two arrows indicate that the dotted line is 3 inches above the solid line that is the current ground level. One arrow goes from the end of the word inches to the dotted line the other is short and goes up from below pointing at the solid line.]&lt;br /&gt;
&lt;br /&gt;
:[Caption below the panel:]&lt;br /&gt;
:The UK shut down their last coal power plant today, which means that over the course of the industrial revolution, they dug up and burned an average of 3 inches of their country.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
This is another comic in the [[:Category:My Hobby|My Hobby]] series.&lt;br /&gt;
&lt;br /&gt;
Parentheses are generally used in a sentence to add additional information that clarifies the topic. For example, in the sentence, &amp;quot;{{w|Barack Obama}} (a Democrat) is the 44th President of the United States,&amp;quot; the parenthetical clause clarifies who Obama is, but is not strictly necessary to the sentence. However, in the comic, Randall uses parentheses for where they are not needed, either because the subject needs no clarification or because the parenthetical clause is so important to the subject that it should not be relegated to parentheses. &lt;br /&gt;
&lt;br /&gt;
''{{w|Sonic the Hedgehog}}'' is a video game franchise featuring the eponymous Sonic the Hedgehog character. Sonic is also the name of a {{w|Sonic (train)|train}}, a {{w|Sonic Drive-In|restaurant franchise}}, and a {{w|Sonic (ISP)|Californian internet service provider}}, among other things Randall is trying to avoid confusing the hedgehog with; however, it is unlikely that any of these would have movies made about them.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
{{w|Jack the Ripper}} is the name attributed to a {{w|serial killer}} active in {{w|London}} in 1888. His true identity has never been confirmed, and he has been featured in {{w|Jack the Ripper in fiction|hundreds of works}}. {{w|Jack (given name)|&amp;quot;Jack&amp;quot;}} is one of the most-common given names for males in much of the Anglosphere.&lt;br /&gt;
&lt;br /&gt;
{{w|Popeye|Popeye the Sailor}} is a cartoon character created in 1929, and has been adapted for feature film, television, comic books, and other media. Popeye the Sailor is the best-known character named &amp;quot;Popeye&amp;quot;, so it is a little unusual that Randall would have to clarify ''which'' Popeye he is referring to. Other Popeyes include {{w|Jimmy &amp;quot;Popeye&amp;quot; Doyle}} from ''{{w|The French Connection}}'' and the criminal {{w|Popeye (Faulkner character)|Popeye}} from {{w|William Faulkner|William Faulkner's}} novel ''{{w|Sanctuary (Faulkner novel)|Sanctuary}}''.  Like &amp;quot;Sonic&amp;quot;, there is a restaurant chain named &amp;quot;{{w|Popeyes}}&amp;quot;, which is the second-largest fast-food chicken restaurant chain in the world (after KFC).&lt;br /&gt;
&lt;br /&gt;
The title-text alters the pattern slightly by discussing the {{w|Battle of Midway}} (i.e. the X '''of''' Y).  This case has additional humor because Randall clarifies which battle he is talking about, but not which of the several movies depicting the battle (although he was most likely referring to the film released in November 2019, simply called {{w|Midway (2019 film)|''Midway''}}).&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BELT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic depicts an attempted connection of three {{w|Ferris wheel}}s using a belt drive, a system typically used to transfer motion between rotating shafts. By connecting the wheels at different circumferences, the relative motion is geared up or down. If the belt passes around the circumference of one wheel and is connected around the hub of another, the latter will rotate significantly faster. In this case, the second wheel's circumference is in turn connected to a third wheel's hub, resulting in even greater rotational velocity. However, this setup is mechanically unsound and possibly dangerous, as Ferris wheels are not intended to be connected in this way.{{cn}} As shown, the first wheel on the left is running at a normal speed, while the other two are rotating increasingly fast, leading to a potentially hazardous situation where passengers are flung around at various (possibly {{w|G-force#Human tolerance|quite hazardous}}) extents.&lt;br /&gt;
&lt;br /&gt;
The ratio (give or take a pixel) seems to be approximately 12.5:1&amp;lt;!-- which seems to be the most 'sane' ratio that can be derived as the probable intent from the various ways of measuring the various sizes, assuming it's not just totally adhoc and not *meant* to be any particular ratio... --&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Effectively, this system converts the linked wheels into a belt-and-pulley system. For a two-pulley system with one driving pulley and one driven pulley, the system can be described by d1*r1 = d2*r2, where d1 and d2 are the radii of the driving and driven pulleys, respectively; and r1 and r2 are the rates of revolution of the two pulleys. A typical Ferris wheel has a diameter (d1) of approximately 200 ft. The speed that Ferris wheels rotate varies somewhat; many are set to complete a single rotation (r1) in about 10 minutes. It is unclear how large the central hub pulley is on the second Ferris wheel in this illustration, but a plausible estimate is that it is about 10 ft across. Plugging these numbers into the pulley formula, we conclude that the driven pulley -- the hub of the second Ferris wheel, and thus the second Ferris wheel itself -- would spin about about 2 rpm. Cars on this wheel would be traveling at about 1250 feet per minute, or about 14 miles per hour. This is almost certainly faster than the safety limits on most Ferris wheels, but would likely not be otherwise dangerous to the passengers (who would experience only about 0.15 G of force). &lt;br /&gt;
&lt;br /&gt;
However, the second Ferris wheel is then used to drive a third. Using the same diameter assumptions, this would drive the final wheel at 40 rotations per minute, or a full circle every 1.5 seconds. At this speed, the cars would be traveling at over 400 feet per ''second'', or at about 285 miles per hour. Even assuming the structure did not fail, passengers would experience instantly fatal conditions, something on the order of 54 Gs of centrifugal force.&lt;br /&gt;
&lt;br /&gt;
The caption suggests that the person responsible was fired for this ill-advised modification, highlighting the impracticality and dangers of the idea. &lt;br /&gt;
&lt;br /&gt;
The title text imagines the consequences of leaving the belt drive system in place but switching which wheel is powered. If the most extreme wheel (the third one on the right) is powered, the gearing would be reversed, making for a possibly pleasant and normal ride on the right-hand wheel, but rendering the experiences of the riders on the other two wheels far too slow and seemingly interminable. One revolution of the center wheel might take three hours and twenty minutes, while the left wheel would take multiple days per revolution. &amp;lt;!-- Based on the ratios above; I didn't do the intermediate math. Also, this wiki has comments? Neat! --&amp;gt; This exaggerates the impracticality and unintended effects of using a belt drive system on Ferris wheels, humorously illustrating how such an idea would lead to absurdly varied ride experiences.&lt;br /&gt;
&lt;br /&gt;
A cruise line fired a person due to an unsound engineering solution earlier in [[2935: Ocean Loop]].&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BOT'S PINEAL GLAND - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
This is a graph by [[Randall]] ranking how well he understands the function of certain human organs, compared to how much he understands {{w|metaphor}}s using them. &amp;lt;!-- REPLACEMENT PHRASES URGENTLY NEEDED HERE; A &amp;quot;SILVER TONGUE&amp;quot; IS METAPHORICAL TO (QUICK?)SILVER, NOT THE TONGUE, ETC; CLEARLY &amp;quot;THE TONGUE OF THE &amp;lt;SOME OTHER THING/PRINCIPLE&amp;gt;&amp;quot; IS RATED VERY LOW ON RANDALL'S UNDERSTANDING. AND MINE. For example, a person who has a &amp;quot;silver tongue&amp;quot; doesn't have a literal silver tongue, but is very persuasive when speaking, while to &amp;quot;bite one's tongue&amp;quot; means to stop yourself from saying something you would really like to say. --&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A number of organs (and other body parts) are used in common vernacular for metaphorical meaning. The English language is full of sayings like &amp;quot;she had a lot of heart&amp;quot;, &amp;quot;go with your gut&amp;quot;, and &amp;quot;he hasn't got the stomach for it&amp;quot;. One might expect understanding an organ's role and its use in metaphor to be strongly correlated, since the metaphors generally work by drawing a parallel to biological function. However, since our understanding of biological functions has evolved dramatically over time, and metaphorical language does not always keep up, the correspondence is often much looser. To complicate matters, many such anatomical metaphors vary from culture to culture, even though the biological functions remain largely consistent.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
The {{w|pineal gland}}, located in the center of the brain, was described as the &amp;quot;Seat of the Soul&amp;quot; by the {{w|Mind–body dualism|mind-body dualist}} {{w|René Descartes}} in the 17th century. If this was true, the metaphors that might be derived from it would be quite clear. It was only in the mid-20th century that its real neuroendocrine (hormone-producing) biological role was grasped. Thus, the real meaning of the metaphor &amp;quot;the pineal gland of something&amp;quot; is uncertain, as is its actual function for the layman. It was also described as a &amp;quot;third eye&amp;quot;, as its regulation of the circadian rhythm used to be linked to light perception in the organ, and still is in {{w|Tuatara|Tuataras}}. It is also jokingly stated as still the location of the soul within discordianism.&lt;br /&gt;
&lt;br /&gt;
The {{w|thymus}}, highlighted in the title text, plays an important role in the immune system. It is not commonly used in metaphors,{{Citation needed}} but is perhaps ripe for use in ones describing such things as resilience, indomitability, and adaptability to changing circumstance, were more people to know what it was.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a COSMIC SPAGHETTI BOWL - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
In {{w|Timeline_of_the_far_future|less than 5 billion years}} into the future, the {{w|Andromeda Galaxy}} is expected to {{w|Andromeda–Milky Way collision|collide}} with the {{w|Milky Way}}. This comic suggests this will happen when both galaxies get into a kissing distance after having slurped the same cosmic spaghetti strand. This is a spoof of a famous scene in the movie ''{{w|Lady and the Tramp}}'', where the titular dogs are eating spaghetti at an Italian restaurant. They happen to be eating the same strand from opposite ends, so they end up meeting in the middle and kissing. This scene was mentioned before in [[2612: Lightsabers]], and {{tvtropes|SpaghettiKiss|has been referenced extensively in other media}}.&lt;br /&gt;
&lt;br /&gt;
It's possible that this is also a reference to {{w|Flying_Spaghetti_Monster|Pastafarianism}}, the spoof religion which claims that the universe was created by a &amp;quot;flying spaghetti monster&amp;quot;. If both galaxies are eating one of the deity's &amp;quot;noodly appendages,&amp;quot; they may be doing what the monster wishes, since one of the religion's holidays is about eating lots of pasta.&lt;br /&gt;
&lt;br /&gt;
The title text figure of 200 septillion (2×10&amp;lt;sup&amp;gt;26&amp;lt;/sup&amp;gt;) calories for the Milky Way-Andromeda noodle equates to approximately 2500 calories per foot of noodle. This value makes sense only if Randall is referring to the physics/chemistry {{w|Calorie|&amp;quot;small&amp;quot; calorie}} (= 4.184 joules) rather than the dietary {{w|Calorie|&amp;quot;large&amp;quot; Calorie}} (= 4184 joules). Dietary Calories, also called kilocalories (kcal), would be the usual meaning in a food-related context like this one, but Randall was trained as a physicist and apparently used the small calorie here. Having 2.5 dietary Calories per foot is roughly correct for a noodle size between thin spaghetti and angel hair. A noodle with similar ingredients and 2,500 dietary calories per foot would be roughly 26 centimeters in diameter, and might more properly be considered a type of pastry.&lt;br /&gt;
&lt;br /&gt;
The nutritional value of dark matter refers to the fact that evidence of 'dark matter' is particularly found in [https://www.nature.com/articles/nature11224 cosmic filaments] and the [https://www.space.com/dark-matter-detected-cosmic-web-filaments-universe-evolution-subaru-telescope cosmic web], implying that such &amp;quot;cosmic spaghetti&amp;quot; would have an appreciable amount of dark matter &amp;quot;sauce&amp;quot; on it. But, because the exact nature of dark matter is unknown, it is likely even more difficult to identify the calorific content that it might provide. Note that these {{w|galactic filament|filaments}} are much larger structures than the {{w|Local Group}} of galaxies that includes the Milky Way and Andromeda.&lt;br /&gt;

==Explanation==&lt;br /&gt;
This [[:Category:New Year|New Year comic]] plays out at what is, probably, a {{w|New Year}} party thrown by [[Danish]]. (The previous New Year day comic in 2007 was also related to a wild party: [[364: Responsible Behavior]]).&lt;br /&gt;
&lt;br /&gt;
In the first panel, we see [[Black Hat]] telling [[Cueball]] that he has hired {{w|Rick Astley}} to show up at a party for a girl. Cueball, assuming Rick Astley is going to perform a live Rickroll, asks if it isn't a little &amp;quot;last year&amp;quot;. &lt;br /&gt;
{{w|Rickrolling}} is where one is redirected to a video of Rick Astley singing &amp;quot;{{w|Never Gonna Give You Up}}&amp;quot; via a weblink purporting to be something else. It was later extended to any situation where the song is used disruptively, such as during a party. It started in 2006 and grew until peaking on April Fool's Day in 2008. Thus, at New Years Eve 2008, the meme was getting old.{{citation needed}} However, Black Hat assures Cueball that Rick Astley is not actually going to sing.&lt;br /&gt;
&lt;br /&gt;
The comic then continues to the now ongoing party and we see the girl in question, [[Danish]], Black Hat's girlfriend, talking with [[Ponytail]] when she notices Rick Astley at her party. Like Cueball, Danish expects Rick Astley is going to sing and Rickroll her. She obviously hates this idea and braces her self for the humiliation of being Rickrolled, but she is freaked out when he just stands there staring at her, but without singing. In the end, his presence alone causes her to hear the song in her head instead, and finally she flees the room screaming, slamming a door behind her. Black Hat has essentially Rickrolled her in her own mind, which is far worse than just playing a song for her, but Black Hat could not have done so without the willing assistance from Rick!{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
When Ponytail asks Rick Astley &amp;quot;what did you do to her?&amp;quot;, he begins by saying &amp;quot;that, my dear&amp;quot; and then slowly [[:Category:Puts on sunglasses|puts on sunglasses]] before he answers &amp;quot;Is how &amp;lt;u&amp;gt;I&amp;lt;/u&amp;gt; roll.&amp;quot;  This references both Rickrolling and the [https://english.stackexchange.com/questions/115813/origin-of-how-we-i-roll|&amp;quot;that's how I roll&amp;quot;] meme.&lt;br /&gt;
&lt;br /&gt;
Although the identity of the girl Black Hat is pranking is not stated by [[Randall]] (he refers to her as Girl 1), there is a theory that she is Danish, Black Hat's girlfriend. However, Danish would likely ordinarily play it cool and be entirely unruffled by something like this. Most agree that this behaviour is more akin to Megan, as she can assume all sorts of various reactions to stimuli depending on what Randall decides is appropriate in that instance.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the fact that Rickrolling first appeared in 2007 (on {{w|4chan}}) and became viral for over a year. Given that this is a New Year comic, it is thus relevant to ask what meme will replace Rickrolling in the new year, 2009. Although [[Randall]] makes reference to the &amp;quot;[https://knowyourmeme.com/memes/xzibit-yo-dawg Xzibit Yo Dawg]&amp;quot; and &amp;quot;[https://knowyourmeme.com/memes/i-accidentally I accidentally...]&amp;quot; photocaptioning memes, {{w|memebase}} entries suggest the &amp;quot;Keep Calm and Carry On&amp;quot; meme may well have become the most popular (and most enduring, as of 2013) meme of 2009.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
As of 2024, Rickrolling is still one of the most relevant memes from that era. There are many [https://www.youtube.com/watch?v=xvFZjo5PgG0 articles] on why that is.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is a satirical {{w|infographic}}, which is usually used to simplify and help visualize information that would be dreadfully boring otherwise. [[Randall]] takes this &amp;quot;simplification&amp;quot; to the extreme by making an unhelpful infographic, complete with unnecessary data and ironic and blatant misuse of common graphs and charts. At this point, he is not even simplifying his sentence &amp;quot;By the year 2019, all information will be communicated in this clear and concise format.&amp;quot; He makes a sarcastic claim, pointing out how needlessly complicated some infographics make things they are supposed to condense.&lt;br /&gt;
&lt;br /&gt;
In the chart:&lt;br /&gt;
*The number 2019 is huge and placed between the numbers 2018 and 2020, which is bordering on extraneous considering that the fact that 2019 precedes 2020 and succeeds 2018 is blindingly obvious.{{Citation needed}}&lt;br /&gt;
*The graph of information represented by this format is extrapolated off of and intersects with 100% at 2019. This is a running joke on xkcd and is ridiculous for multiple reasons, as shown in [[605: Extrapolating]] and [[1007: Sustainable]], for example.&lt;br /&gt;
*The word &amp;quot;information&amp;quot; has the letters &amp;quot;info&amp;quot; highlighted differently for the typical abbreviation despite the text splitting after the &amp;quot;r&amp;quot;, a rather silly graphical styling.&lt;br /&gt;
*A pie chart, with one part labeled &amp;quot;will&amp;quot; and one part labeled &amp;quot;be&amp;quot;, which is completely nonsensical as pie charts show the proportional relationship of parts of a whole (for instance, people up to 30 years old and over 30 years old in a human population), and &amp;quot;will&amp;quot; and &amp;quot;be&amp;quot; are merely words and the chart isn't showing their proportional representation in a population. It may be showing the proportional length of each word in a sentence, though this could also be accomplished by showing both words in a normal sentence.&lt;br /&gt;
*&amp;quot;6 years from now&amp;quot; is more blindingly obvious fact at the time (2013).&lt;br /&gt;
*&amp;quot;72 months&amp;quot; is an unneeded and obvious conversion from six years; it is also {{w|false precision}} as 2019 (January 1) arrives 63 months from the comic date. The word &amp;quot;months&amp;quot; is also split across two lines, mid-syllable.&lt;br /&gt;
*A corny illustration of [[Megan]] telling [[Hairy]] the word &amp;quot;communicated&amp;quot; and Hairy enthusiastically responding &amp;quot;Yes!&amp;quot;, despite the absurdity of the situation.&lt;br /&gt;
*The word &amp;quot;this&amp;quot; in huge font, and the word &amp;quot;in&amp;quot; with a bracket, taking up an inordinate amount of space.&lt;br /&gt;
*A {{w|Venn diagram}}. As anyone who has seen a Venn diagram knows, the two circles are two concepts or qualities, and objects or concepts that fit inside the circles go within. The words &amp;quot;clear and concise&amp;quot; plastered across the Venn diagram have absolutely nothing to do with Venn diagrams, and are ludicrously inappropriate for this jumbled and overblown presentation, but the word &amp;quot;AND&amp;quot; is in the intersection of the two circles, which is meta-humorous.&lt;br /&gt;
*In the lowermost bar graph, the bar height shows the alphabetic position of each letter of the word ''FORMAT'' (the bar labeled &amp;quot;F&amp;quot; has a height of 6, the &amp;quot;O&amp;quot; bar has a height of 15, etc.), with T highlighted because it is the highest. And possibly because the bars for the other letters form a visually pleasing 'arc'-segment, leaving the 'T'-bar as a statistical outlier deemed 'worthy' of note.&lt;br /&gt;
&lt;br /&gt;
It is also likely that this comic is a send up of the recent trend towards presenting information in tall graphics that are easily viewed on smartphone screens. A tall graphic with the same pixel width as an iPhone, for example, can be viewed without zooming and using only vertical scrolling. Another discussion venue for the topic and this comic is [http://gizmodo.com/tall-infographics-suck-1441047853 Gizmodo: Tall Infographics Suck].&lt;br /&gt;
&lt;br /&gt;
The prediction communicated in the comic did not actually happen by the year 2019. Alternatively, it did happen but was reversed so quickly nobody noticed it happened. However, in the 2020s, the rise of tiktok and vertical short form video has led to more and more information being communicated in a tangentially similar format. &lt;br /&gt;
&lt;br /&gt;
The title text mentions the often-hyped term &amp;quot;{{w|big data}}.&amp;quot; &amp;quot;Big data&amp;quot; normally refers to the challenges of working with and visualizing a quantity of data which is hard to process using traditional tools and methods. Randall, now speaking unsarcastically, tells us that just because the font size is huge doesn't mean you have handled the big data well.&lt;br /&gt;

| titletext = Pythagorean means are nice and all, but throwing the median in the pot is really what turns this into random forest statistics: applying every function you can think of, and then gradually dropping the ones that make the result worse.&lt;br /&gt;
}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
This is another one of [[Randall|Randall's]] [[:Category:Tips|Tips]], this time a stats tip. This came as the first tip comic after the statistics tip in [[2400: Statistics]].&lt;br /&gt;
&lt;br /&gt;
There are a number of different ways to identify the &amp;quot;{{w|average}}&amp;quot; value of a series of values, the most common unweighted methods being the {{w|median}} (take the central value from the ordered list of values if there are an odd number - or the value half-way between the two that straddle the divide between two halves if there are an even number) and the {{w|arithmetic mean}} (add all the numbers up, divide by the number of numbers). The {{w|geometric mean}} is less well-known but works similarly to the arithmetic mean. The geometric mean of ''n'' positive numbers is the ''n''th root of the product of those numbers. If all of the numbers in a sequence are identical, then its arithmetic mean, geometric mean and median will be identical, since they would all be equal to the common value of the terms of the sequence. However, if the sequence is not constant, then {{w|Inequality_of_arithmetic_and_geometric_means#Geometric_interpretation|the arithmetic mean will be greater than the geometric mean}}, and the median may be different than either of those means.&lt;br /&gt;
&lt;br /&gt;
The geometric mean, arithmetic mean, and the {{w|harmonic mean}} (not shown) are collectively known as the {{w|Pythagorean means}}, as specific modes of a greater and more generalized mean formula that extends arbitrarily to various other possible nuances of mean-value rationisations (cubic, etc.).&lt;br /&gt;
&lt;br /&gt;
{{w|Outlier}}s and internal biases within the original sample can make boiling down a set of values into a single 'average' sometimes overly biased by flaws in the data, with your choice of which method to use perhaps resulting in a value that is misleading, exaggerating or suppressing the significance of any blips.&lt;br /&gt;
&lt;br /&gt;
In this depiction, the three named methods of averaging are embedded within a single function that produces a sequence of three values - one output for each of the methods. Being a series of values, Randall suggests that this is ideally suited to being ''itself'' subjected to the comparative 'averaging' method. Not just once, but as many times as it takes to narrow down to a sequence of three values that are very close to one another. &lt;br /&gt;
&lt;br /&gt;
It can be shown that the xkcd value of 2.089 for GMDN(1,1,2,3,5) is validated:&lt;br /&gt;

&lt;br /&gt;
The function GMDN in the comic is properly defined in the second row since F acts on a vector to produce another three vector, however GMDN in the last line is shown to produce a single real number rather than a vector and is thus missing a final operation of returning a single component. Each row in this table shows the set Fn(..) composed of the average, geomean and median computed on the previous row, with the sequence {1,1,2,3,5} as the initial F0. While GMDN is not differentiable, due to the median, this can be interpreted as somewhat similar to a heat equation which approaches equilibrium through averaging. Interestingly, the maximum value alternates between the average and the median (highlighted in bold in the table), while the minimum value alternates between the geomean and the median. This holds for many inputs thus providing the basis for a possible proof-by-induction of convergence on the range (see discussions).&lt;br /&gt;
&lt;br /&gt;
The comment in the title text about suggests that this will save you the trouble of committing to the 'wrong' analysis as it gradually shaves down any 'outlier average' that is unduly affected by anomalies in the original inputs. It is a method without any danger of divergence of values, since all three averaging methods stay within the interval covering the input values (and two of them will stay strictly within that interval).&lt;br /&gt;
&lt;br /&gt;
The title text may also be a sly reference to an actual mathematical theorem, namely that if one performs this procedure only using the arithmetic mean and the harmonic mean, the result will converge to the geometric mean. Randall suggests that the (non-Pythagorean) median, which does not have such good mathematical properties with relation to convergence, is, in fact, the secret sauce in his definition.&lt;br /&gt;
&lt;br /&gt;
The question of being unsure of which mean to use is especially relevant for the arithmetic and harmonic means in following example.&lt;br /&gt;
   * Cueball has some US Dollars and wishes to buy Euros. Suppose the bank will exchange US Dollars to Euros at a rate of €5 for $6 (about 0.83333€/$ or 1.20000$/€).&lt;br /&gt;
   * Megan   has some Euros and wishes to buy US Dollars. Suppose the bank will exchange Euros to US Dollars at a rate of $7 for €6 (about 0.85714€/$ or 1.16667$/€).&lt;br /&gt;
[[Cueball]] and [[Megan]] decide to complete the exchange between themselves in order to save the {{w|Bid-ask spread}} of the {{w|Exchange rate}} which is the cost the bank imposes on Cueball and Megan for its service as a {{w|Market maker}}. &lt;br /&gt;
   * Cueball offers to split the difference by averaging the rates €5:$6 and €6:$7 yielding a rate of €71:$84 (about 0.84524€/$ or 1.18310$/€).&lt;br /&gt;
   * Megan   offers to split the difference by averaging the rates $6:€5 and $7:€6 yielding a rate of €60:$71 (about 0.84507€/$ or 1.18333$/€).&lt;br /&gt;
In one direction (€/$), Cueball is using the arithmetic mean but Megan is using the harmonic mean while in the other direction ($/€), Megan is using the arithmetic mean but Cueball is using the harmonic mean. This creates two new exchange rates which are closer than the orginal rates, but the new rates are still different for each other. Megan and Cueball can then iterate this process and the rates will converge to the geometric mean of the original rates, namely:&lt;br /&gt;
   * sqrt((5/6)*(6/7)) = sqrt(5/7) = 0.84515€/$ or&lt;br /&gt;
   * sqrt((6/5)*(7/6)) = sqrt(7/5) = 1.18322$/€.&lt;br /&gt;
&lt;br /&gt;
There does exist an {{w|arithmetic-geometric mean}}, which is defined identically to this except with the arithmetic and geometric means, and sees some use in calculus.  In some ways it's also philosophically similar to the {{w|truncated mean}} (extremities of the value range, e.g. the highest and lowest 10%s, are ignored as not acceptable and not counted) or {{w|Winsorized mean}} (instead of ignored, the values are readjusted to be the chosen floor/ceiling values that they lie beyond, to still effectively be counted as &amp;quot;edge&amp;quot; conditions), only with a strange dilution-and-compromise method rather than one where quantities can be culled or neutered just for being unexpectedly different from most of the other data.&lt;br /&gt;
&lt;br /&gt;
The input sequence of numbers (1, 1, 2, 3, 5) chosen by Randall is also the opening of the {{w|Fibonacci sequence}}.  This may have been selected because the Fibonacci sequence also has a convergent property: the ratio of two adjacent numbers in the sequence approaches the [https://en.wikipedia.org/wiki/Golden_ratio#Relationship_to_Fibonacci_sequence golden ratio] as the length of the sequence approaches infinity.&lt;br /&gt;
&lt;br /&gt;

Caption: Stats tip: If you aren't sure whether to use the mean, median, or geometric mean, just calculate all three, then repeat until it converges&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
Geothm means &amp;quot;counting earths&amp;quot; (From Ancient Greek γεω- (geō-), combining form of γῆ (gê, “earth”) and ἀριθμός arithmos, 'counting').  Geothmetic means &amp;quot;art of Geothming&amp;quot; based on the etymology of Arithmetic (from Ancient Greek ἀριθμητική (τέχνη) (arithmētikḗ (tékhnē), “(art of) counting”).  This is an exciting new terminology that is eminently suitable for modern cosmology &amp;amp; high energy physics - particularly when doing math on the multiverse.  However, it is unlikely this etymology is related to the term &amp;quot;geothmetic meandian&amp;quot; as coined by Randall, as it can be more simply explained as a portmanteau of the three averages in its construction: '''geo'''metric mean, ari'''thmetic mean''', and me'''dian'''.&lt;br /&gt;
&lt;br /&gt;
The following Python code (inefficiently) implements the above algorithm:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
from functools import reduce&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
def f(*args):&lt;br /&gt;
    args = sorted(args)&lt;br /&gt;
    mean = sum(args) / len(args)&lt;br /&gt;
    gmean = reduce(lambda x, y: x * y, args) ** (1 / len(args))&lt;br /&gt;
    if len(args) % 2:&lt;br /&gt;
        median = args[len(args) // 2]&lt;br /&gt;
    else:&lt;br /&gt;
        median = (args[len(args) // 2] + args[len(args) // 2 - 1]) / 2&lt;br /&gt;
    return mean, gmean, median&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
max_iterations = 10&lt;br /&gt;
l = [1, 1, 2, 3, 5]&lt;br /&gt;
for iterations in range(max_iterations):&lt;br /&gt;
    fst, *rest = l&lt;br /&gt;
    if all((abs(r - fst) &amp;lt; 0.00000001 for r in rest)):&lt;br /&gt;
        break&lt;br /&gt;
    l = f(*l)&lt;br /&gt;
print(l[0], iterations)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Here is a slightly more efficient version of the Python code:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
from scipy.stats.mstats import gmean&lt;br /&gt;
import numpy as np&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
def get_centers(a, tol=0.00001, print_rows = True):&lt;br /&gt;
    a = np.array(a)&lt;br /&gt;
    l_of_a = len(a)&lt;br /&gt;
    if l_of_a == 1:&lt;br /&gt;
        return a[0]&lt;br /&gt;
    elif l_of_a &amp;gt; 2: &lt;br /&gt;
        result = all(&lt;br /&gt;
            (&lt;br /&gt;
                np.abs(a[0] / a[1]) &amp;lt;= tol,&lt;br /&gt;
                np.abs(a[0] / a[2]) &amp;lt;= tol,&lt;br /&gt;
                np.abs(a[1] / a[2]) &amp;lt;= tol,&lt;br /&gt;
            )&lt;br /&gt;
        )&lt;br /&gt;
        if result:&lt;br /&gt;
            return a[0]&lt;br /&gt;
    res = [np.mean(a), np.median(a), gmean(a)]&lt;br /&gt;
&lt;br /&gt;
    if print_rows:&lt;br /&gt;
        print(res)&lt;br /&gt;
    return get_centers(res, tol)&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
And here is an implementation of the Gmdn function in R:&lt;br /&gt;
&lt;br /&gt;
    Gmdn &amp;lt;- function (..., threshold = 1E-6) {&lt;br /&gt;
      # Function F(x) as defined in comic&lt;br /&gt;
      f &amp;lt;- function (x) {&lt;br /&gt;
        n &amp;lt;- length(x)&lt;br /&gt;
        return(c(mean(x), prod(x)^(1/n), median(x)))&lt;br /&gt;
      }&lt;br /&gt;
      # Extract input vector from ... argument&lt;br /&gt;
      x &amp;lt;- c(...)&lt;br /&gt;
      # Iterate until the standard deviation of f(x) reaches a threshold&lt;br /&gt;
      while (sd(x) &amp;gt; threshold) x &amp;lt;- f(x)&lt;br /&gt;
      # Return the mean of the final triplet&lt;br /&gt;
      return(mean(x))&lt;br /&gt;
    }&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
{{comic discussion}}&lt;br /&gt;
&amp;lt;!--&lt;br /&gt;
For a start, there is a syntax error. After the first application of F, you get a 3-tuple. Subsequent iterations preserve the 3-tuple, and we need to analyze the resulting sequence.&lt;br /&gt;
Perhaps there is an implicit claim all three entries converge to the same result. In any case, lets see what we get:&lt;br /&gt;
&lt;br /&gt;
Wlog, we have three inputs (x_1,y_1,z_1), and want to understand the iterates of the map &lt;br /&gt;
F(x,y,z) = ( (x+y+z)/3, cube root of (xyz), median(x,y,z) ). Lets write F(x_n,y_n,z_n) = (x_{n+1},y_{n+1},z_{n+1}).&lt;br /&gt;
&lt;br /&gt;
The inequality of arithmetic and geometric means gives x_n \geq y_n, if n \geq 2,  and&lt;br /&gt;

The room code 020518 as listed consists of prime numbers 2 and 5 (with 3 missing). however both are preceded by a zero. The 18 is interpreted as non prime (it is not) but the 2x3x3 seems a bit far off from any prime. Would the alternative explanation 0-5 is a zero followed by the prime number five --- followed by 1 - 8 which is 0+1 and 7+1 which could be logical continuation of 0+0-5+0, 0+1-7+1, followed by e.g. 0+2, 11+2 etc. - as such series sometime go.

By the above logic, (2^n) iteself would quite close to being a prime (being another prime-pair's intermediate) whilst being quite conspicuously factorisable to the ''n''th order.

Outside Europe, these patterns hold, up until some pale jerks from across the sea start threatening people who worship gods they don't like. (And sometimes even after that.) The exceptions to the rule are exceptionally popular and influential (especially in English-speaking parts of the world, natch), but that doesn't make them the Real Rule that all other religions deviate from.

What if there is a God, but they don't want you to believe in them?[[Special:Contributions/172.70.86.35|172.70.86.35]] 11:48, 18 June 2024 (UTC)&lt;br /&gt;

:Or a God, and he just wants to screw over us all (not in the Yivo sense, mind you)? (Under this condition, all three outcomes are possible: he wants us to believe, he wants to hide, he couldn't care less) [[Special:Contributions/198.41.242.174|198.41.242.174]] 08:05, 19 June 2024 (UTC)&lt;br /&gt;

How did the middle Cueball on line 3 not realize that both Gods he was being asked to believe in are the same God (since the ones on line 2 both got it from the same Cueball on line 1)? Is there also a game of Telephone going on? [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 14:29, 18 June 2024 (UTC)&lt;br /&gt;
:Tbf there's no clarification by the Line 2 guys that they're talking about the same God. It makes sense that he'd assume they're different. If two different religious people told you at the same time &amp;quot;My God is real&amp;quot; and you'd never really been exposed to religion or atheism, you would assume they were talking about two. Forgive me if I made any unfair assumptions here. [[User:Psychoticpotato|P?sych??otic?pot??at???o ]] ([[User talk:Psychoticpotato|talk]]) 15:34, 18 June 2024 (UTC)&lt;br /&gt;
:Look at the schism in Islam and the huge number of divisions in Christianity. That it may be the same god and same basic religion doesn't mean that it isn't presented entirely differently. For example (what I'm familiar with), Roman Catholic versus Church of England. Similar, but also completely different.

&lt;br /&gt;

&lt;br /&gt;
I very nearly inserted the following 'argument' paragraph in the Explanation, but decided that it perhaps was a bit of a 'belief' of my own.&lt;br /&gt;
 (A more realistic approach could be to just outwardly conform to the social expectations of the society to which you belong. With or without any actual core belief, which cannot be tested in any realistic manner during your lifetime, maintaining a performative cohesion with your neighbours and acquaintences would still benefit you in avoiding standing out from the commonly accepted ideology. This may still count as a 'belief' (desirable or undesirable) should this stance ever come to be judged by any deity, with your ultimate fate probably being mirrored by others that you know who are in your exact same ideological position and merely outwardly perpetuting the 'accepted' demonstrations of faith. Assuming that the society's religion is not a self-destructive one, you would have as good a lifetime as circumstances would generally allow, with the ''possibility'' of an afterlife that is at least not uniquely bad for you; unlike the smart-arse who presumes to know what the single best theological stance is and then has to rationalise their attempt to cynically play the odds upon Judgement Day, against a deity who fully understands their base motivations and may even take far less kindly towards a Wagerer than with someone who never ever tried to 'believe' but at least was generally and secularly philanthropic in a way that the deity might be pleased by.)&lt;br /&gt;
I stand by the logic, as far as it can ever be taken (without knowing anything useful about the actual mind of God/gods it has to be tested against) but it got a bit long as a 'minor philosophical interlude'. And if the Ultimate Arbiter does ''not'' like Bill-And-Ted-ism (i.e. &amp;quot;be excellent to each other&amp;quot;) and getting along with your community, instead prefers more outstandingly misanthropic worldly behaviours (because the only 'heavenly' afterlife is more Valhalla than Asphodel Meadows; anyone who even mildly disappoints goes to the Hades/Tartarus equivalent) without actually clueing us in on this particular Ineffable Plan, then the fate of many (who ''don't'' make earthly lives more miserable for the rest of us) is pretty much doomed from the start and even the most perfect Pascalian Wagerer probably never managed to stand on the right side of the philosophical barrier either. This whole argument is not even a novel philosophy, of course, but it's mine. [[Special:Contributions/172.69.195.56|172.69.195.56]] 16:36, 21 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
Doesn't the exact wording of the alt text not technically call for a classic Pascal's Wager, but rather an inverted triangle where there is only one number at the bottom, two in the row above the bottom, et cetera? (Since there have to be two numbers above every number: the traditional exception for the top row and the numbers at the sides isn't present.) Given such a triangle, wouldn't the only possible solutions be all-0, all-positive-infinity, or all-negative-infinity, which certain readings of &amp;quot;number&amp;quot; might restrict to the all-0 solution? [[User:WingedCat|WingedCat]] ([[User talk:WingedCat|talk]]) 00:20, 22 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
'''''PROBLEM''''': Currently, the transcript includes a recreation of the triangle, nicknaming the Cueballs C1 through 15, laid out in a triangle. This seems too visual for the transcript. The thing is, it seems like a major goal of the transcript is for blind people, who have a reader program read them the transcript, and they follow XKCD solely in this way. Wouldn't a reader program render this as &amp;quot;C1 C2 C3...&amp;quot; etc? Giving no indication as to the layout? As the fix feels rather clunky and I'm not 100% sure this is an issue, I felt I should mention it first before enacting change. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:07, 23 June 2024 (UTC)&lt;br /&gt;
:Extended the Transcript to perhaps help cater for this issue. Maybe too wordy. Maybe a mistake to mention what ''isn't'' there (except in explaining the full spirit of the diagram). But hopefully more mentally re-constructable by anyone with a visual imagination. [[Special:Contributions/172.70.86.9|172.70.86.9]] 19:25, 23 June 2024 (UTC)&lt;/div&gt;</summary>

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|BREAKING! This article fails to explain the BREAKING aspect of the comic and its prevalence in (US) media. BREAKING!}}&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Breaking news&amp;quot; is a phrase which describes news reports which are considered important enough to interrupt (or &amp;quot;break&amp;quot;) scheduled broadcasts. The phrase is often used to describe scheduled reports on important current events. When a new development in an active story occurs, news channels will often interview an expert in the field to educate laymen in what, exactly, is happening. Thus, when you turn on the local news and see a scientist being interviewed, it is likely that something new has come up regarding their field of study that could affect you.&lt;br /&gt;
&lt;br /&gt;
How much it affects you could range from an interesting bit of information about your local area, to the complete annihilation of the human race. So, to help identify how serious the issue likely is, [[Randall]] has made this chart showing how worried you should be depending on the field of the scientist. A [[#The fields of science|table]] has been arranged to explain the amount of worry needed for each field below.&lt;br /&gt;
&lt;br /&gt;
To the far left, the least worrying are {{w|archaeologist}} and {{w|economist}}. An archaeologist studies ancient human civilizations, which would be unlikely to harm any modern person. Economists study and explain the trends of finances and resources, which are also unlikely to pose an immediate threat.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
Following this, it shows {{w|Nutrition|nutritionists}} and eventually {{w|criminologists}}. A nutritionist studies nutrition in the human body, and is likely discussing which food options are healthy or unhealthy. While this may be important, it is not a cause for immediate concern. A criminologist, however, studies criminal behavior. If a criminologist is being interviewed on the news, there is likely a change in criminal actions within the neighborhood, be it more or less. It is also possible there may be a serial criminal working in the area. However, because crime is a relatively rare occurrence, and one for which precautions can be taken, it is still unlikely to be an immediate threat to the viewer.&lt;br /&gt;
&lt;br /&gt;
It then moves past researchers studying different types of organisms, before reaching astronomers. Still only very few events would be local regarding astronomy, but it could of course be regarding a pending meteor strike.&lt;br /&gt;
&lt;br /&gt;
A {{w|virologist}} studies {{w|Virus|viral}} infections and their spread, and a {{w|vulcanologist}} studies {{w|volcanoes}}. Viruses spread quickly, and can be fatal, meaning a breaking news development in one's locale regarding viruses is likely to mean imminent danger. Volcanoes, depending on their size, can potentially demolish entire countries, thus having one making headlines nearby is also very concerning.&lt;br /&gt;
&lt;br /&gt;
The last point to the right (most worried) &amp;quot;Astronomer who studies the Sun&amp;quot;, also called a &amp;quot;{{w|solar physicist}}&amp;quot; (mentioned in the title text), could be really troublesome, but not especially locally. If there are serious problems with the Sun it will be a world-wide problem. But you should still be worried. &lt;br /&gt;
&lt;br /&gt;
The title text mentions that the reason they are not called solar physicists, is that before they can tell the reporter this, they are interrupted by the anxious reporter who wishes to know what's wrong with the Sun. This is not really something that happens so often{{Citation needed}} that the title texts &amp;quot;They always try&amp;quot; has any real meaning. And this is also why no one knows or uses the term solar physicists...&lt;br /&gt;
&lt;br /&gt;
==The fields of science==&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! Field !! Worry level !! Explanation&lt;br /&gt;
|-&lt;br /&gt;
| Archeologist || Extremely low (~2.7%) || Likely just dug up some old ruins or bones. Unlikely to involve bad news, though it may possibly cause problems (e.g. if a construction project is delayed to accommodate an archaeological investigation).&lt;br /&gt;
|-&lt;br /&gt;
| Economist || Very low (~7.3%) || News about the economy could be either good or bad, and in most cases is just more of the usual ups and downs rather than anything cataclysmic. Could also be a report on a big stock market crash.&lt;br /&gt;
|-&lt;br /&gt;
| Nutritionist || Very low (~12.0%) || Possible fad diet. Note that nutritionists tend not to be a protected profession, compared to dietitians. May be alarming if it involves credible information about bad health consequences of eating, or not eating, a particular food.&lt;br /&gt;
|-&lt;br /&gt;
| Criminologist || Low (~26.6%) || Probably just crime statistics. Sometimes just correcting people who mistakenly believe crime is on the rise, and even a large increase in an otherwise ordinary crime rate is still a small risk overall. Specific threats (such as a dangerous criminal on the loose) are usually addressed by police representatives.&lt;br /&gt;
|-&lt;br /&gt;
| Ornithologist || Medium (~43.3%) || This would indicate the discovery of a strange behavior exhibited by birds. A newsworthy event involving ornithologists could indicate some imminent problem with the ecological environment, such as a mass migration or death event suggesting toxic pollutants in the environment. A possible reference to ''{{w|The_Birds_(film)|The Birds}}'' or ''{{w|Birdemic}}'', two films with similar premises (horror films centered around flocks of birds suddenly becoming hostile to humans) but vastly different critical evaluations (''The Birds'' was directed by {{w|Alfred Hitchcock}} and is generally considered a classic; ''Birdemic'' was low-budget and is notoriously poor-quality).&lt;br /&gt;
|-&lt;br /&gt;
| Botanist || Medium (~46.0%) || Similar to an ornithological related news. Seeing how plants are both more fundamental to the environment and more &amp;quot;boring&amp;quot; to the general public than birds; if something news worthy involves a botanist, then it is more likely a more fundamental and more impactful change to the environment.&lt;br /&gt;
|-&lt;br /&gt;
| Marine Biologist || Medium (~53.3%) || Similar to Botanist news. However, as oceans represent the substantial majority of the Earth's surface, and are very far removed from local concerns, anything which is news-worthy of them is likely a major impact to the environment on a global scale.&lt;br /&gt;
|-&lt;br /&gt;
| Entomologist || Medium high (~62.6%) || There might be a new invasive insect species that could cause health concerns, ranging from {{w|Locust|famine}} to {{w|Mosquito|blood-transmitted diseases}}.&lt;br /&gt;
|-&lt;br /&gt;
| Astronomer || High (~82.0%) || Possible inbound meteor, or perhaps sighting of incoming alien ships.&lt;br /&gt;
|-&lt;br /&gt;
| Virologist || Very high (~88.0%) || A disease that is incurable and spreads fast might ravage or even destroy a city, country, or (in an extreme case) all human life. An example of a worrisome virus is {{w|COVID-19}},{{Citation needed}} which resulted in many interviews with epidemiologists. &lt;br /&gt;
|-&lt;br /&gt;
| Vulcanologist || Very high (~93.3%) || A volcano might erupt soon, the danger of which could range from an isolated area to a planetwide concern.&lt;br /&gt;
|-&lt;br /&gt;
| Astronomer who studies the Sun || Extremely high (~98.6%) || There might be something wrong with the Sun, the consequences of which could range from {{w|Solar_storm_of_1859|major disruption of modern technology}} to the end of life on earth. The title text elaborates that, [[1475: Technically|technically]], the correct term is &amp;quot;{{w|Solar physics|solar physicist}}&amp;quot;. Unsurprisingly, reporters (and the general audience) aren't particularly interested in such a pedantic matter, and want to be informed about the more pressing issue regarding the fiery ball that maintains the Earth's orbit and capacity for life.{{Citation needed}}&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a PERSON WHO BELIEVED THE TWO BOTS ABOVE HIM - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
The comic is structured in a layout that emulates Pascal's triangle. Pascal's triangle is a numerical triangle where the top is 1 and each value below is the sum of the 2, or in the case of the edges, 1 number(s) above it. For example, a triangle would start with a singular 1, then the next row would have two ones, and the next would have a one, a two, and another one, and so on. In the comic, Cueball is instead wagering his proof of a god to the Cueballs below him, thereby creating Cueballs that believe in a number of gods equal to the sum of the 2 Cueballs above him. Theoretically, this cycle would continue for all integers as the triangle grows. This is clearly not the intent of the first Cueball, who simply wagered the proof of his one god, but he has no control over the situation. &lt;br /&gt;
&lt;br /&gt;
It is not clearly shown what differences would be between the multiple gods that interior Cueballs in the third row and on would be, as they all started from the same one, but as history would show, word of mouth can easily change stories.&lt;br /&gt;
&lt;br /&gt;
The title text also mentions a proper Pascal's Triangle, but one where God would ask you to draw it, meaning theoretically if one did not follow this command, they would be punished.&lt;br /&gt;
&lt;br /&gt;
Pascal's Wager is a philosophical argument proposed by Blaise Pascal. Essentially, if the Bible is true, both the rewards for believing in God and the punishment for nonbelief are infinite; if it is not, the cost of belief and benefit for nonbelief are negligible. Therefore, if there is a finite possibility that the Bible is true, however small, one should believe in God.&lt;br /&gt;
&lt;br /&gt;
Pascal's Triangle is a triangular array of numbers, where each number equals the sum of the two numbers above it. It plays important roles in binomial expansion, probability theory, and other areas of math. While Blaise Pascal did not invent the triangle, it is named after him.&lt;br /&gt;
&lt;br /&gt;
This comic combines the Wager and the Triangle. At the top is a Cueball, proposing a proof for &amp;quot;his god&amp;quot;. The two Cueballs find his philosophical argument compelling, and convince the three Cueballs of their god's existence. Those three do the same, though the Cueball in the middle has interpreted the arguments of the two Cueballs above him as an argument to believe in two different gods. This pattern repeats for two more rows, with the implication that it goes on for some time thereafter.&lt;br /&gt;
&lt;br /&gt;
It is unclear why the Cueballs behave in this fashion. Perhaps each one rewords their arguments for God(s) sufficiently to make them sound different than other gods. This is not without precedent; for instance, scholars of comparative mythology believe that the religion of Proto-Indo-European peoples splintered into many disparate religions of Europe and West Asia.&lt;br /&gt;
&lt;br /&gt;
This comic may be referencing a common counterargument to Pascal's Wager—that it works equally well for any hypothetical god which offers paradise for one action and damnation otherwise. This can even include hypothetical gods with contradictory criteria for entrance into paradise. In this case, the Cueballs apparently chose to believe in ''n'' deities to cover their bases.&lt;br /&gt;
&lt;br /&gt;
The title text proposes Pascal's Triangle Wager, which combines the Triangle and Wager in a different manner. It proposes a potential god who grants salvation to those who construct a copy of Pascal's Triangle.&lt;br /&gt;
&lt;br /&gt;
Pascal's Wager was previously mentioned in the title text of [[525]].&lt;br /&gt;

Isn't the solution to make the competition like skiing: The participants take turns fishing, instead of all fishing at the same time? And they're judged on how quickly they can &amp;quot;catch&amp;quot; a magnet in the water. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:44, 10 June 2024 (UTC)&lt;br /&gt;

:It's also possible that Magnet Fishing is scored in a way where earlier competitors' actions can affect the scoring of later competitors. For instance, if they're scored on the number of objects dredged up, later contestants could have an unfair disadvantage if the objects were not replaced or an unfair advantage if they knew where the objects were replaced. (Or if those objects were originally tangled up in weeds or half-covered in silt, but were now sitting on top of everything.) Of course, this just raises the question of how Magnet Fishing competitions are prepared and scored.

(Also note, in that first link the &amp;quot;groups of 50-60&amp;quot; who gather – maybe multiple people per magnet – and the picture of at least ''three'' magnets being simultaneously worked from the same bridge. But not to dismiss the comic's humour, of course.)&lt;br /&gt;
&amp;lt;br/&amp;gt;I think the problem for the comic was siting the competition in a natural watercourse with a too obviously V-shaped bed. Everyone lowered their magnets straight down into the water, no problem, as even a powerful magnet can't overcome gravity-induced of hanging at that sort of scale of hanging. But then all magnets not already over the thalweg slide away from the bank into it, close enough to start clumping. As the 'prizes'/scorable-finds will also have probably migrated down the benthic slopes, over time, it's in everyone's personal interest to let their magnet tumble that way, if they weren't given 'pole position' directly over the (or 'a') deepest point. If the stream's cut goes significently non-perpendicular to the bridge that crosses it, or it has multiple (low-water) channels dug into its sediment, possibly sensible coordination could allow parallel fishing. Or the rules state that minimal slack be allowed when dipping the magnet-'hook' into the water, and no lateral dragging or swinging allowed, with (judged) penalties for any who cause an 'out of line' contact to occur. I think the ''second'' world championships are entirely feasible, just needs some rethinking of the setting, conditions and competition regulations.

&lt;br /&gt;
&lt;br /&gt;
== Title text ==&lt;br /&gt;
&lt;br /&gt;
I believe the first &amp;quot;ten-way tie&amp;quot; refers to calling the competition a &amp;quot;tie&amp;quot; between ten competitors. It's more common in British English, but can be used as a synonym for game/match/etc. So it's saying &amp;quot;the ten-person match was judged a ten-way draw&amp;quot;. {{unsigned|MightyP|16:36, 10 June 2024}}&lt;br /&gt;
: It's a pun on tie meaning to knot/tangle the lines, and tie in the sense of competitors finishing equally. [[Special:Contributions/172.70.134.117|172.70.134.117]] 18:29, 10 June 2024 (UTC)&lt;br /&gt;
:As a British Englisher(!) myself, I think &amp;quot;cup tie&amp;quot; (e.g. the final culmination of a knockout competition) tends to be what &amp;quot;breaks the tie&amp;quot; between the ''two'' teams that have each reached this stage equally successful against all other opponents. (Also &amp;quot;3rd/4th-place tie&amp;quot;, etc.) You don't tend to get N-way competitions called a 'tie' (though, theoretically, a trifurcated bracketing system could bring 27 teams in nine games teams could become nine teams in three games, then three three teams producing the winner, etc).&lt;br /&gt;
:Tie/tangle and tie/equally-scored is going to be good enough. If Randall had thought of the &amp;quot;cup tie&amp;quot;-type usage, he could have easily made a tripled-pun version with that ''and'' the two more obvious versions. [[Special:Contributions/172.70.160.248|172.70.160.248]] 21:30, 10 June 2024 (UTC)&lt;br /&gt;
:Is it more common in British English? I'm American and I usually say &amp;quot;tie&amp;quot; to refer to a draw. I also see it be used frequently in American media. [[User:GreyFox|GreyFox]] ([[User talk:GreyFox|talk]]) 21:53, 11 June 2024 (UTC)&lt;br /&gt;
::Unless you're using &amp;quot;draw&amp;quot; as in the randomised pairing of competitors (prior to the match), that's not the issue. Tie-as-in-equally-scoring and Tie-as-in-knotted seem (mostly) unambiuous, here. Tie-as-in-knockout-game (early rounds perhaps being arranged by being drawn, by ballot, so &amp;quot;tied by a draw&amp;quot; in a different sense) seems to be the one mentioned as being British-usage biased. [[Special:Contributions/172.69.195.183|172.69.195.183]] 09:19, 12 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
The prize is also a bit of wordplay. It refers to a magnetic monopole as already noted, but is also a joke, as a regular fishing pole is technically a &amp;quot;monopole&amp;quot;. I've never personally seen a fishing dipole, but I suppose they could exist! {{unsigned|MightyP|16:49, 10 June 2024}}&lt;br /&gt;
&lt;br /&gt;
== Triple pun for some speakers ==&lt;br /&gt;
&lt;br /&gt;
I found it funny that in Austrian, monopole is &amp;quot;Monopol&amp;quot;, and we use the same word for monopole and monopoly!&lt;br /&gt;
The prize also feels special if you have a monopoly on magnet fishing - without all the others interfering with your magnet like in the comic.&lt;br /&gt;
&lt;br /&gt;
First time ever posting here. Keep up the good spirit! [[Special:Contributions/172.68.50.13|172.68.50.13]] 20:45, 10 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
Quadruple pun: I (german) thought for the same reason, that the prize is the exclusive right for (magnetic) fishing at a certain (rare implies very good) spot. Indeed, that might be a very valuable entitlement and plausible prize in a fishing championship.&lt;br /&gt;
&lt;br /&gt;
== Monopoles ==&lt;br /&gt;
&lt;br /&gt;
If you did have a magnetic monopole... Would the field lines look a lot like the strings in this comic?&lt;br /&gt;
&lt;br /&gt;
: It could in the Arctic ocean with a south monopole! Near the monopole the field lines point inward but far away they point in the direction of Earth's field. There are parts of the Arctic ocean with a 90 degree inclination and the lines are vertical instead of north-to-south. Monopoles also have two advantages: The field drops off inverse-square instead of of inverse-cube, giving the &amp;quot;hook&amp;quot; a longer range. Also, if all contestants have the same kind of monopole they will repel instead of sticking to each-other.&lt;br /&gt;
&lt;br /&gt;
: [[Special:Contributions/172.70.80.121|172.70.80.121]] 00:17, 11 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
:: If the contestans' monopoles repelled each other, things could get pretty chaotic with so many of them in close proximity. None of the monopoles would be in a stable position, so the fishing lines would tangle up even worse than if they were all dipoles attracted to each other.&lt;br /&gt;
:: [[Special:Contributions/141.101.98.56|141.101.98.56]] 05:36, 11 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
The picture obviously shows a Tenpole Tudor. &amp;lt;runs for his life&amp;gt; [[Special:Contributions/172.71.160.114|172.71.160.114]] 06:19, 11 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
The magnetic field lines coming out of a magnetic monopole look very much like the fishing lines coming away from the magnets all stuck together in the comic.  The first thing I thought when I saw the title and the picture was that Randell was drawing a magnetic monopole.&lt;br /&gt;
Warm regards, Rick. {{unsigned ip|162.158.146.33|06:50, 11 June 2024}}&lt;br /&gt;
&lt;br /&gt;
If the lures are magnetic because the fish (as in commercial magnetic fishing games) contain magnets, a monopole lure only solves half the problem: The fish either need their fields to be kept separated or they need (the opposite) monopoles, too?   &lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
This is yet another comic part of the [[:Category:COVID-19|series of comics]] on the {{w|COVID-19 pandemic}}.&lt;br /&gt;
&lt;br /&gt;
This comic is a chart that orders things based on the level of alarm that would occur if it were revealed that someone had not done a given thing since early 2020. Many of the items, but not all, are linked to new constraints due to the pandemic.&lt;br /&gt;
&lt;br /&gt;
The title text serves as another chart point, though it isn't given where it is on the chart. &lt;br /&gt;
&lt;br /&gt;
;Been to a birthday party &lt;br /&gt;
Going to a birthday party was a normal task before the pandemic, and it's normal to say you haven't gone to one since early 2020. &lt;br /&gt;
&lt;br /&gt;
;Eaten at a restaurant &lt;br /&gt;
Eating at a restaurant was also common before governments instated lockdowns, but during the lockdowns many restaurants had to limit their service to delivery and take-out.&lt;br /&gt;
&lt;br /&gt;
;Seen my family&lt;br /&gt;
Seeing your family was fairly common before the governments instated lockdowns. However, there were emergency visits during the lockdown period.&lt;br /&gt;
&lt;br /&gt;
;Been on a plane&lt;br /&gt;
Governments around the world cancelled commercial flights during the pandemic. However, businessmen like Bill Gates used private jets during the pandemic.&lt;br /&gt;
&lt;br /&gt;
;Gone to a movie&lt;br /&gt;
Many cinema halls around the world closed due to the pandemic. Several movies were instead released directly to TV via OTT platforms.&lt;br /&gt;
&lt;br /&gt;
;Gone to a store&lt;br /&gt;
Although some stores were closed during the lockdown period, others were open for essential commodities. Therefore, going to a store for the first time since early 2020 is little strange.&lt;br /&gt;
&lt;br /&gt;
;Installed software updates&lt;br /&gt;
Regularly installing software updates is recommended, mainly for security reasons. However, many people don't follow these recommendations (mostly by fear of software inconsistency or instability), although a delay of more than one year is quite long. Mentioning software updates is weird, because it is not directly related to the COVID pandemic. On the contrary, since many people spent much more time at home and worked at home, it was all the more important to keep software up to date, especially due to zero-day exploits.&lt;br /&gt;
&lt;br /&gt;
;Eaten a vegetable&lt;br /&gt;
Since vegetables are essential to a healthy diet, not eating a single vegetable in a whole year is not recommended.{{citation needed}} Anxiety due to the pandemic and disruption of social relations may have caused people to consume more junk food than usual.&lt;br /&gt;
&lt;br /&gt;
;Opened the fridge&lt;br /&gt;
This is quite weird, since most people use their refrigerators to store fresh food. Maybe some people became anorexic because of anxiety due to the pandemic or stopped consuming fresh food and relied more on junk food. Moreover, most food products will alter or rot if stored in a fridge for more than one year, and become dangerous to eat.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
;Paid taxes&lt;br /&gt;
Although some people, depending on where they live and their income, may not pay taxes in an immediately obvious way, there are some taxes, such as {{w|VAT}} in many countries and {{w|sales tax}} in the United States or Canada, which almost everyone would pay in the natural course of everyday life, though may not be 'obvious' in the paying, or even be extracted at source (withheld from payroll) in the simpler cases. (Randall lives in {{w|Massachusetts}}, which does not have a VAT, but does have a 6.25% sales tax.) It is therefore strange that someone could have gone a year without paying any taxes, implying they made almost no monetary transactions in the period, nor are made (directly) responsible for any residential or property-owning taxations that might otherwise be payable to one or other layer of government.&lt;br /&gt;
&lt;br /&gt;
If the statement refers specifically to filing income taxes (which is often the case when people refer to &amp;quot;taxes&amp;quot;, because the paperwork and large sums of money transferred at once makes the income tax highly noticeable and memorable), it might describe someone who filed a tax return for 2019 early in 2020 and then waited until later in 2021 to file a return for 2020.&lt;br /&gt;
&lt;br /&gt;
;Washed my hands&lt;br /&gt;
One of the main pieces of advice during the pandemic was to wash one's hands, frequently. Even in normal circumstances, washing hands is a good idea to remain hygienic,{{citation needed}} and not do so for a year would be disgusting to most people, and a good way of catching diseases.&lt;br /&gt;
&lt;br /&gt;
Like paying taxes, it is very common to wash one's hands inadvertently as part of another activity, so someone who actually has not washed their hands since early 2020 likely also never bathed or showered.&lt;br /&gt;
&lt;br /&gt;
;Seen another person&lt;br /&gt;
Despite the restrictions, most people will have seen another person during the pandemic, virtually or otherwise.&lt;br /&gt;
&lt;br /&gt;
;Seen a ghost&lt;br /&gt;
The fact that the speaker apparently has seen a ghost, both now and presumably before early 2020 (else they would simply say it was the 'first time' they saw a ghost) is unusual.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
In addition, it is possible that someone who tells you that they haven't seen a ghost recently is implying that ''you'' are a ghost they currently see. If true, this would be quite alarming to most people.&lt;br /&gt;
&lt;br /&gt;
;Served as a decoy&lt;br /&gt;
Similar to the previous point, this is not a normal activity, so the specificity is unusual.&lt;br /&gt;
&lt;br /&gt;
;Sighted land&lt;br /&gt;
Most people live on land,{{citation needed}} so sighting land should not be unusual, even during a pandemic. The fact that someone has gone over a year without sighting land suggests they have been lost at sea for the duration. There are several reported cases of ships' crews refused permission to disembark, due to local restrictions and/or because their scheduled relief were unable to embark, but the unluckily held-on persons forced to remain beyond their originally planned obligations should never have been left permanently beyond any tantalizingly unreachable view of the shore.&lt;br /&gt;
&lt;br /&gt;
Taken more literally, it could simply mean that the person remained indoors and did not look outside, or that the person was temporarily blind.&lt;br /&gt;
&lt;br /&gt;
;Checked the news&lt;br /&gt;
If someone has not checked the news since early 2020, they will likely be in for a shock upon checking. Noting that this could possibly (if increasingly absurdly) still apply to someone like [[Ponytail]] (as portrayed in strip [[2396: Wonder Woman 1984]]).&lt;br /&gt;
&lt;br /&gt;
;Checked on the customers in the {{w|escape room}}&lt;br /&gt;
The implication is that the customers in question have been trapped in the escape room since early 2020. Most escape rooms are not equipped to support a person for that length of time, so unless the customers actually escaped, they would likely not have survived.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
;Contracted a novel bat virus&lt;br /&gt;
As a 'novel bat virus' is what kicked off the whole pandemic, contracting another one may send the whole world into a new pandemic, which is certainly alarming.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
;Gotten the Ferris wheel operator's attention (title text)&lt;br /&gt;
It seems that the speaker has been stuck in a {{w|Ferris wheel}} for a year. It is unclear how they may have survived, unless the speaker is [[Beret Guy|a certain xkcd character]].&lt;br /&gt;
&lt;br /&gt;
Alternately, it would be perfectly normal that the speaker has not been at an amusement park with a working Ferris wheel since early 2020 - but it would be unusual to focus on interacting with the operator versus enjoying the attraction.&lt;br /&gt;
&lt;br /&gt;
Several [https://ask.metafilter.com/78414/The-Rotating-Prison-in-the-Mountain science fiction stories] include wheel-like prisons where people stay for years, but generally they are underground and horizontal rather than in the air and vertical like Ferris wheels are.&lt;br /&gt;

==Trivia==&lt;br /&gt;
&lt;br /&gt;
On July 6, 2021, four weeks after the release of this comic, an emergency patch update was released for Windows 7. Since support for Windows 7 had otherwise ended in mid-January 2020, this means that people whose computers ran Windows 7 could have installed software updates for the first time since early 2020.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by a GOLGI ENDOPLASMIC RETICULUM. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic depicts a {{w|Cell (biology)|biological cell}} diagram with a mix of real and fictional {{w|organelle}}s, blending accurate {{w|Cell biology|cell biology}} terms with misplaced or absurd labels. While it includes actual cell components like the nucleus, mitochondria, and Golgi apparatus, it also includes unrelated concepts from various fields such as geology, engineering, software, and pop culture. Labels like &amp;quot;evil endoplasmic reticulum&amp;quot; and &amp;quot;sticky endoplasmic reticulum&amp;quot; make fun of scientific terms. The comic plays on the complexity and diversity of cell structures by mixing in unrelated and humorous terms, highlighting the often confusing and intricate nature of scientific diagrams with clever wordplay and cross-disciplinary jokes.&lt;br /&gt;
&lt;br /&gt;
The title text adds a humorous fictional backstory to the {{w|Golgi apparatus}}, an essential cell organelle involved in processing and packaging proteins. It playfully suggests that {{w|Camillo Golgi}}, the scientist who discovered the Golgi apparatus, was originally an independent organism. This organism was supposedly absorbed into our cells, where it then started working on what is now known as the Golgi apparatus. The joke is a satirical take on {{w|Symbiogenesis|endosymbiotic theory}}, which posits that certain organelles within {{w|Eukaryote|eukaryotic}} cells, like {{w|mitochondria}} and {{w|chloroplasts}}, originated from independent symbiotic {{w|Prokaryote|prokaryotic organisms}} that were absorbed by a host {{w|germ cell}}. Golgi appears to be depicted in the comic as a tiny alien being.&lt;br /&gt;

| titletext = Cosmologists estimate the spaghetti strand to be about 200 septillion calories, though it could be higher depending on the nutritional value of dark matter.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a COSMIC SPAGHETTI BOWL - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
In {{w|Timeline_of_the_far_future|less than 5 billion years}} into the future, the {{w|Andromeda Galaxy}} is expected to {{w|Andromeda–Milky Way collision|collide}} with the {{w|Milky Way}}. This comic suggests this will happen when both galaxies get into a kissing distance after having slurped the same cosmic spaghetti strand. This is a spoof of a famous scene in the movie ''{{w|Lady and the Tramp}}'', where the titular dogs are eating spaghetti at an Italian restaurant. They happen to be eating the same strand from opposite ends, so they end up meeting in the middle and kissing. This scene was mentioned before in [[2612: Lightsabers]], and [[https://tvtropes.org/pmwiki/pmwiki.php/Main/SpaghettiKiss has been referenced extensively in other media]].&lt;br /&gt;
&lt;br /&gt;
It's possible that this is also a reference to {{w|Flying_Spaghetti_Monster|Pastafarianism}}, the spoof religion which claims that the universe was created by a &amp;quot;flying spaghetti monster&amp;quot;. If both galaxies are eating one of the deity's &amp;quot;noodly appendages,&amp;quot; they may be doing what the monster wishes, since one of the religion's holidays is about eating lots of pasta.&lt;br /&gt;
&lt;br /&gt;
The title text figure of 200 septillion (2×10&amp;lt;sup&amp;gt;26&amp;lt;/sup&amp;gt;) calories for the Milky Way-Andromeda noodle equates to approximately 2500 calories per foot of noodle. This value makes sense only if Randall is referring to the physics/chemistry {{w|Calorie|&amp;quot;small&amp;quot; calorie}} (= 4.184 joules) rather than the dietary {{w|Calorie|&amp;quot;large&amp;quot; Calorie}} (= 4184 joules). Dietary Calories, also called kilocalories (kcal), would be the usual meaning in a food-related context like this one, but Randall was trained as a physicist and apparently used the small calorie here. Having 2.5 dietary Calories per foot is roughly correct for a noodle size between thin spaghetti and angel hair.&lt;br /&gt;
&lt;br /&gt;
The nutritional value of dark matter refers to the fact that evidence of 'dark matter' is particularly found in [https://www.nature.com/articles/nature11224 cosmic filaments] and the [https://www.space.com/dark-matter-detected-cosmic-web-filaments-universe-evolution-subaru-telescope cosmic web], implying that such &amp;quot;cosmic spaghetti&amp;quot; would have an appreciable amount of dark matter &amp;quot;sauce&amp;quot; on it. But, because the exact nature of dark matter is unknown, it is likely even more difficult to identify the calorific content that it might provide. Note that these {{w|galactic filament|filaments}} are much larger structures than the {{w|Local Group}} of galaxies that includes the Milky Way and Andromeda.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Many politicians and organizations in the United States have taken to using email to conduct aggressive fundraising drives seeking campaign contributions. Signing a petition or expressing interest in a cause can lead to being added to a myriad of mailing lists for similar groups, all looking for support. This comic shows a caricature of the kind of inbox that can result from this. The emails get more and more absurd as the list goes on. For example, the last one combines a request for campaign contributions with the infamous 'Nigerian prince' {{w|advance-fee scam}} emails.&lt;br /&gt;
&lt;br /&gt;
{| border =1 width=100% cellpadding=5 class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
! E-mail Body !! Explanation&lt;br /&gt;
|-&lt;br /&gt;
|'''Donate now.''' It's crunch time, and we're low on cash. If you chip in just $5 by midnight, we…&lt;br /&gt;
|This is the classic formula for campaign fundraising emails, and may be a real example. It is always &amp;quot;crunch time&amp;quot; during a campaign (at least between filing for candidacy and election day), and campaigns are always &amp;quot;low&amp;quot; on cash relative to the unlimited funding they would prefer.  The ends of financial reporting periods, often at midnight, are conflated with &amp;quot;deadlines&amp;quot; of significant consequence.  Further, the donation requested is less about the actual money - even if $5 each from several thousand voters can add up - but to get a donor to have their money placed on a candidate, making it more likely that donor will vote for the candidate (via encouraging {{w|Sunk cost#Loss_aversion_and_the_sunk_cost_fallacy|the &amp;quot;sunk cost&amp;quot; fallacy}}), or to allow the targeting of future messages based on how engaged the recipient is with the campaign.&lt;br /&gt;
|-&lt;br /&gt;
|'''Donate $35.57 now!''' Our data team has determined that we should ask you for $35.57 to optimize the…&lt;br /&gt;
|A key factor in the success of a fundraising campaign is the amount of the donation that is asked for or suggested. Even if the donor is ultimately free to donate whatever amount they want, the initial 'ask' can have a significant effect on the amount donated, due to the psychological effect of {{w|Anchoring (cognitive bias)|anchoring}}. Increasing the suggested amount may increase the amount of the average donation, but it may also put some people off donating altogether. Finding the sweetspot allows the fundraiser to maximize the income generated.&lt;br /&gt;
&lt;br /&gt;
Most modern bulk mailing platforms allow users send different versions of their emails to recipients at random. Using analytics packages, they can then determine which version of their messages is most effective at eliciting the desired result (such as making a purchase, reading a story, etc.) from recipients, or even from particular segments, and to refine future emails accordingly. Use of these techniques has resulted in fundraisers moving away from traditional 'round' numbers ($10, $25, etc.) to ask for more unusual looking amounts which increase the average amount donated, either by exploiting {{w|Psychological pricing|such effects}} as the &amp;quot;99 cent&amp;quot; phenomenon or giving those that ask an appearance of 'knowing what they're talking about' to give the potential donor the impression that they're good with details and wouldn't be overwhelmed by the pressures of being in office.&lt;br /&gt;
&lt;br /&gt;
However, it would be unusual to use quite such a precise amount told them, which may actually appear cynical in its attempt to bleed the donor to a maximal amount, and put many off donating altogether. This is rather than at least the pretense to be coming directly from a more optimal and restrained need/capability calculation. The email then compounds this by stating outright that this is what they have done, and entirely sheds any of the veil of it not being calculated ''simply'' to manipulate the recipient (even/especially if it had not been recalculated to differing odd values for each recipient), plus explicitly suggest that someone other than the message author did this so no longer conveys much of any innate confidence and trustworthiness one might have had in the sender themself.&lt;br /&gt;
|-&lt;br /&gt;
|'''Help.''' Our campaign made some mistakes and we need a lot of money ASAP. Any kind, but cash is…&lt;br /&gt;
|This email is honest about the campaign's incompetence, but is not likely to get much sympathy, except perhaps from those already very sympathetic to the candidate. Any campaign reduced to this level has probably already lost. The email appears to be suggesting that they would much prefer that donors send cash, presumably in the mail. This would raise several red flags: it might suggest that the campaign's finances are in such disarray that it cannot process checks, credit cards, etc. in a timely manner, or it might be that they want to keep donations off the books so that they can be diverted elsewhere, or to circumvent electoral spending restrictions. Even if no dishonesty is intended, it would increase the chances that cash could be stolen or otherwise misused more readily than other forms of payment.&lt;br /&gt;
|-&lt;br /&gt;
|'''Washington is broken.''' When I win, I'll look those other senators in the eye and tell them: &amp;quot;Jobs.&amp;quot; Then I…&lt;br /&gt;
|This email, apparently from a candidate for the US Senate, takes a common populist approach of repeating particular phrases to imply that they will stand up for the interests of the common people against a system that is rigged against them, without giving any meaningful indication of what they intend to achieve. Not only is the mere statement of &amp;quot;jobs&amp;quot;, without any kind of explanation of what problems they believe there are, or what they suggest doing about it, entirely unhelpful, they also seem to suggest that, despite them being elected, it would be everybody else's responsibility to solve it.&lt;br /&gt;
|-&lt;br /&gt;
|'''Hopeless.''' It's bad. Really bad. If you don't chip in now, the darkness spreading across the land will…&lt;br /&gt;
|This is a favorite of moral campaigns, on both sides of a debate. Grand statements about evil and corruption taking over the country if the campaign does not get enough support are common, but they are extremely biased and dramatic.  The wording in this case is also somewhat archaic and melodramatic, making it sound like something from a fantasy novel.&lt;br /&gt;
This might also refer to [[1391: Darkness]], where everyone forgets about the day and night cycle, and reporters are reporting on the darkness that has spread as far west as Texas.&lt;br /&gt;
|-&lt;br /&gt;
|As the first woman to fly a fighter jet through our state's formerly all-male university, I learned…&lt;br /&gt;
|Candidates often like to portray themselves as trailblazers for a particular community, who have persevered and achieved despite the odds. Normally, one would make a virtue of being the first ''from'' a university to do something, rather than the first to achieve something involving the university itself. Flying a plane through a university is risky, at the very least,{{Citation needed}} and depending on the definition of &amp;quot;through&amp;quot;, could imply destruction of buildings or the plane itself, which might paint the candidate in an irresponsible light. The implication of &amp;quot;formerly all-male university&amp;quot; may be that the university was changed from being all-male in response to this candidate wrecking it with a fighter jet. This may also refer to the viral 2017 Congressional campaign ad of {{w|Amy McGrath}}, the first female Marine to fly an {{w|McDonnell Douglas F/A-18 Hornet|F-18}} in combat.&lt;br /&gt;
|-&lt;br /&gt;
|'''We're broke.''' No paid staff. No ads. And the cafe has told us to stop using their WiFi to send fundraising…&lt;br /&gt;
| This campaign tactic attempts to appeal to the reader's sympathy by describing financial struggles and poverty, but these tactics may instead make the movement look pathetic and poorly-organized, especially because the group is apparently so poor, they can't afford premises of their own to run the campaign from, or an internet connection to continue sending emails to ask for funding.&lt;br /&gt;
|-&lt;br /&gt;
|When Amy decided to run for Congress, I was like &amp;quot;Huh?&amp;quot; but I checked Wikipedia, and apparently it's a branch of…&lt;br /&gt;
|The first few words here might suggest the writer is about to explain how, having initially been skeptical, Amy's inspirational message and/or character has won them over to her campaign. This kind of message is used to make a candidate seem relatable and credible. In fact, though, they just didn't know what she was talking about, as they didn't know what Congress was. Since they clearly don't know much about the subject, this would fail to lend the weight it is aiming to.&lt;br /&gt;
&lt;br /&gt;
Furthermore, while a familiar tone could also be part of a communication strategy to make the message seem relatable, this takes it to an extreme that would probably come across as unprofessional and lacking in seriousness.&lt;br /&gt;
|-&lt;br /&gt;
|'''Are you familiar''' with the Dutch painter Hieronymus Bosch? His work illustrates my opponent's plan for…&lt;br /&gt;
|The works of {{w|Hieronymus Bosch}} are famous for depictions of {{w|Hell}} and {{w|Limbo}} as brutal places of highly imaginative torments, which the sender implies would be similar to the country under their opponent's plan. This mocks the tendency of political campaigns to present an exaggerated view of how bad things would be if their political rivals were elected.&lt;br /&gt;
|-&lt;br /&gt;
|Being a single mom running a small business while going to law school while being deployed to Iraq taught me…&lt;br /&gt;
|Each of these are typical credentials that a candidate might cite in order to imply that they are hardworking and committed. However, it is extremely unlikely that one person would take on all of these responsibilities at the same time, and attempting to do so might suggest that they lack focus and aren't really that committed to any one thing. Also, it would be very difficult for someone to do all of these things simultaneously (e.g. running a small business while deployed in Iraq), so the person might come across as lying in order to impress people.&lt;br /&gt;
|-&lt;br /&gt;
|'''I will lead the fight''' against the big banks, special interests, the Earth's climate, and our children. I…&lt;br /&gt;
|This is another populist message listing off hot button topics. However, after starting out with some typical promises to fight fairly commonly despised things, it then becomes more controversial. It promises to fight the climate, with the peculiar implication that damaging the climate is the goal, and 'our children', which most voters would think would need protecting. This may be suggesting that politicians using these kind of messages are likely to be hiding bad intentions behind their attractive sounding slogans (or they may be just trying and failing to write a populist message without fully understanding it). The fight &amp;quot;against our children&amp;quot; may be a reference to a popular {{w|Bushism}}.&lt;br /&gt;
|-&lt;br /&gt;
|'''Wow.''' Have you seen this video of the squirrel obstacle course? Incredible! Anyway, I'm running because I…&lt;br /&gt;
|A typical form of {{w|clickbait}}. (Don't read another table entry until you've followed that link! Reference #10 will shock you).

|'''Outrageous.''' Granted, this was a few years ago, but did you hear what President Ford said about…&lt;br /&gt;
|When a politician makes an offensive comment, it's common for the politician's opponents to send out fundraising emails pointing out the politician's offensiveness as a way of generating donations to the fight against them. Political strategists will often keep dossiers of such remarks to be used when needed in campaigning season. More recently, there has been a trend for trawling opponents' social media accounts for controversial comments they may have made several years previously, or even as a youth. Here, the sender's reaction and e-mail fundraising effort appears to be unusually delayed, as it refers to an alleged comment by {{w|Gerald Ford}} (potentially a reference to his infamous gaffe that there was &amp;quot;no Soviet domination in Eastern Europe&amp;quot;), whose term as President of the United States ended in 1977 and who died in 2006.&lt;br /&gt;

|The email apologizes for running months of attack ads against American actor {{w|Tom Hanks}}. Hanks is generally a popular and uncontroversial figure with [http://archive.boston.com/ae/celebrity/articles/2008/01/06/nice_guy_tom_hanks/ a reputation] for being [https://www.ranker.com/list/tom-hanks-was-the-best/lisa-waugh nice and likable in person], making him an unusual target for attack ads. This implies that the sender does not even know who their opponent is, and has mistakenly targeted the wrong person, demonstrating some significant ignorance and incompetence.&lt;br /&gt;

|In multi-candidacy electoral races, campaigns will often suggest that a rival 'can't win here', sometimes prefaced with an appeal to authority, such as 'Polls show...'. The hope is that some supporters of the candidate being attacked may be persuaded to switch their vote to the candidate whose campaign it is, in an effort to prevent a third, more disliked, candidate from being elected. Here, the approach seems to be a campaign mocking the opposition's statements about themselves, defiantly exhibiting the negative feedback against them before leading into some point to prove the arguments wrong. However, the complaints being mocked seem like serious flaws in the campaign, and indeed, it seems to confess that they ''already lost'', and thus have no purpose for a campaign anymore. Any campaign continuing to email supporters after losing is clearly in deep denial, especially if it thinks the negative press about it is unjustified. &lt;br /&gt;
&lt;br /&gt;
This may refer to {{w|Roy Moore#U.S. Senate special election campaign|Roy Moore's attempts}} to overturn his loss in the December 2017 election for one of Alabama's US Senate seats, which came about a month before this comic and made national headlines. After the initial election count had him losing, he demanded a recount. That initial count said he had lost by a large enough margin that Alabama law required him to pay up front for a recount, and his campaign did not have enough funds available.&lt;br /&gt;

In reality, there is no ActBlue family, nor any &amp;quot;Jennifer ActBlue&amp;quot; who is the heir to its fortune; the name ActBlue is a portmanteau from the words &amp;quot;action&amp;quot;, in a political sense, and the color &amp;quot;blue&amp;quot;, which is {{w|Red states and blue states|closely associated}} with the Democratic Party in the USA. Even if Jennifer ActBlue was a real heiress, a candidate whose only hope to win revolved around seducing a wealthy woman would be facing serious problems.&lt;br /&gt;

Where is the helm and the hauberk, and the bright hair flowing? &amp;lt;br /&amp;gt;&lt;br /&gt;
Where is the hand on the harpstring, and the red fire glowing? &amp;lt;br /&amp;gt;&lt;br /&gt;
Where is the spring and the harvest and the tall corn growing? &amp;lt;br /&amp;gt;&lt;br /&gt;
They have passed like rain on the mountain, like a wind in the meadow; &amp;lt;br /&amp;gt;&lt;br /&gt;
The days have gone down in the West behind the hills into shadow. &amp;lt;br /&amp;gt;&lt;br /&gt;

|'''Warmest greetings.''' I am the crown prince of Nigeria. I am running for Congress because I believe that…&lt;br /&gt;
|The opening line is designed to sound like spam for an {{W | Advance-fee scam}}. These scams typically involve impersonating someone rich, often a Nigerian prince, who claims to be in trouble and promises to share a large sum of money if the victim helps him by sending a small fee in advance. However, the second sentence of this email switches to sounding like a political fundraising email instead of an outright scam. This is either to establish a degrading comparison between flagrant scams and fundraising emails, or just to create a bait-and-switch joke. Another possibility is that the email sounds like it is a scam because it is a scam.&lt;br /&gt;
Note that a Nigerian crown prince could probably not run for Congress without renouncing his title. Congressional candidates must be citizens of the United States, and gaining US citizenship requires one to &amp;quot;renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which [they] have heretofore been a subject or citizen&amp;quot;.[https://www.ecfr.gov/current/title-8 (citation)] It is unclear how one could renounce allegiance to a state which they expect to rule.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
Many politicians and organizations in the United States have taken to using email to conduct aggressive fundraising drives seeking campaign contributions. Signing a petition or expressing interest in a cause can lead to being added to a myriad of mailing lists for similar groups, all looking for support. This comic shows a caricature of the kind of inbox that can result from this. The emails get more and more absurd as the list goes on. For example, the last one combines a request for campaign contributions with the infamous 'Nigerian prince' {{w|advance-fee scam}} emails.&lt;br /&gt;
&lt;br /&gt;

! E-mail Body !! Explanation&lt;br /&gt;
|-&lt;br /&gt;
|'''Donate now.''' It's crunch time, and we're low on cash. If you chip in just $5 by midnight, we…&lt;br /&gt;
|This is the classic formula for campaign fundraising emails, and may be a real example. It is always &amp;quot;crunch time&amp;quot; during a campaign (at least between filing for candidacy and election day), and campaigns are always &amp;quot;low&amp;quot; on cash relative to the unlimited funding they would prefer.  The ends of financial reporting periods, often at midnight, are conflated with &amp;quot;deadlines&amp;quot; of significant consequence.  Further, the donation requested is less about the actual money - even if $5 each from several thousand voters can add up - but to get a donor to have their money placed on a candidate, making it more likely that donor will vote for the candidate (via encouraging {{w|Sunk cost#Loss_aversion_and_the_sunk_cost_fallacy|the &amp;quot;sunk cost&amp;quot; fallacy}}), or to allow the targeting of future messages based on how engaged the recipient is with the campaign.&lt;br /&gt;
|-&lt;br /&gt;
|'''Donate $35.57 now!''' Our data team has determined that we should ask you for $35.57 to optimize the…&lt;br /&gt;
|A key factor in the success of a fundraising campaign is the amount of the donation that is asked for or suggested. Even if the donor is ultimately free to donate whatever amount they want, the initial 'ask' can have a significant effect on the amount donated, due to the psychological effect of {{w|Anchoring (cognitive bias)|anchoring}}. Increasing the suggested amount may increase the amount of the average donation, but it may also put some people off donating altogether. Finding the sweetspot allows the fundraiser to maximize the income generated.&lt;br /&gt;
&lt;br /&gt;
Most modern bulk mailing platforms allow users send different versions of their emails to recipients at random. Using analytics packages, they can then determine which version of their messages is most effective at eliciting the desired result (such as making a purchase, reading a story, etc.) from recipients, or even from particular segments, and to refine future emails accordingly. Use of these techniques has resulted in fundraisers moving away from traditional 'round' numbers ($10, $25, etc.) to ask for more unusual looking amounts which increase the average amount donated, either by exploiting {{w|Psychological pricing|such effects}} as the &amp;quot;99 cent&amp;quot; phenomenon or giving those that ask an appearance of 'knowing what they're talking about' to give the potential donor the impression that they're good with details and wouldn't be overwhelmed by the pressures of being in office.&lt;br /&gt;
&lt;br /&gt;
However, it would be unusual to use quite such a precise amount told them, which may actually appear cynical in its attempt to bleed the donor to a maximal amount, and put many off donating altogether. This is rather than at least the pretense to be coming directly from a more optimal and restrained need/capability calculation. The email then compounds this by stating outright that this is what they have done, and entirely sheds any of the veil of it not being calculated ''simply'' to manipulate the recipient (even/especially if it had not been recalculated to differing odd values for each recipient), plus explicitly suggest that someone other than the message author did this so no longer conveys much of any innate confidence and trustworthiness one might have had in the sender themself.&lt;br /&gt;
|-&lt;br /&gt;
|'''Help.''' Our campaign made some mistakes and we need a lot of money ASAP. Any kind, but cash is…&lt;br /&gt;
|This email is honest about the campaign's incompetence, but is not likely to get much sympathy, except perhaps from those already very sympathetic to the candidate. Any campaign reduced to this level has probably already lost. The email appears to be suggesting that they would much prefer that donors send cash, presumably in the mail. This would raise several red flags: it might suggest that the campaign's finances are in such disarray that it cannot process checks, credit cards, etc. in a timely manner, or it might be that they want to keep donations off the books so that they can be diverted elsewhere, or to circumvent electoral spending restrictions. Even if no dishonesty is intended, it would increase the chances that cash could be stolen or otherwise misused more readily than other forms of payment.&lt;br /&gt;
|-&lt;br /&gt;
|'''Washington is broken.''' When I win, I'll look those other senators in the eye and tell them: &amp;quot;Jobs.&amp;quot; Then I…&lt;br /&gt;
|This email, apparently from a candidate for the US Senate, takes a common populist approach of repeating particular phrases to imply that they will stand up for the interests of the common people against a system that is rigged against them, without giving any meaningful indication of what they intend to achieve. Not only is the mere statement of &amp;quot;jobs&amp;quot;, without any kind of explanation of what problems they believe there are, or what they suggest doing about it, entirely unhelpful, they also seem to suggest that, despite them being elected, it would be everybody else's responsibility to solve it.&lt;br /&gt;
|-&lt;br /&gt;
|'''Hopeless.''' It's bad. Really bad. If you don't chip in now, the darkness spreading across the land will…&lt;br /&gt;
|This is a favorite of moral campaigns, on both sides of a debate. Grand statements about evil and corruption taking over the country if the campaign does not get enough support are common, but they are extremely biased and dramatic.  The wording in this case is also somewhat archaic and melodramatic, making it sound like something from a fantasy novel.&lt;br /&gt;
This might also refer to [[1391: Darkness]], where everyone forgets about the day and night cycle, and reporters are reporting on the darkness that has spread as far west as Texas.&lt;br /&gt;
|-&lt;br /&gt;
|As the first woman to fly a fighter jet through our state's formerly all-male university, I learned…&lt;br /&gt;
|Candidates often like to portray themselves as trailblazers for a particular community, who have persevered and achieved despite the odds. Normally, one would make a virtue of being the first ''from'' a university to do something, rather than the first to achieve something involving the university itself. Flying a plane through a university is risky, at the very least,{{Citation needed}} and depending on the definition of &amp;quot;through&amp;quot;, could imply destruction of buildings or the plane itself, which might paint the candidate in an irresponsible light. The implication of &amp;quot;formerly all-male university&amp;quot; may be that the university was changed from being all-male in response to this candidate wrecking it with a fighter jet. This may also refer to the viral 2017 Congressional campaign ad of {{w|Amy McGrath}}, the first female Marine to fly an {{w|McDonnell Douglas F/A-18 Hornet|F-18}} in combat.&lt;br /&gt;
|-&lt;br /&gt;
|'''We're broke.''' No paid staff. No ads. And the cafe has told us to stop using their WiFi to send fundraising…&lt;br /&gt;
| This campaign tactic attempts to appeal to the reader's sympathy by describing financial struggles and poverty, but these tactics may instead make the movement look pathetic and poorly-organized, especially because the group is apparently so poor, they can't afford premises of their own to run the campaign from, or an internet connection to continue sending emails to ask for funding.&lt;br /&gt;
|-&lt;br /&gt;
|When Amy decided to run for Congress, I was like &amp;quot;Huh?&amp;quot; but I checked Wikipedia, and apparently it's a branch of…&lt;br /&gt;
|The first few words here might suggest the writer is about to explain how, having initially been skeptical, Amy's inspirational message and/or character has won them over to her campaign. This kind of message is used to make a candidate seem relatable and credible. In fact, though, they just didn't know what she was talking about, as they didn't know what Congress was. Since they clearly don't know much about the subject, this would fail to lend the weight it is aiming to.&lt;br /&gt;
&lt;br /&gt;
Furthermore, while a familiar tone could also be part of a communication strategy to make the message seem relatable, this takes it to an extreme that would probably come across as unprofessional and lacking in seriousness.&lt;br /&gt;
|-&lt;br /&gt;
|'''Are you familiar''' with the Dutch painter Hieronymus Bosch? His work illustrates my opponent's plan for…&lt;br /&gt;
|The works of {{w|Hieronymus Bosch}} are famous for depictions of {{w|Hell}} and {{w|Limbo}} as brutal places of highly imaginative torments, which the sender implies would be similar to the country under their opponent's plan. This mocks the tendency of political campaigns to present an exaggerated view of how bad things would be if their political rivals were elected.&lt;br /&gt;
|-&lt;br /&gt;
|Being a single mom running a small business while going to law school while being deployed to Iraq taught me…&lt;br /&gt;
|Each of these are typical credentials that a candidate might cite in order to imply that they are hardworking and committed. However, it is extremely unlikely that one person would take on all of these responsibilities at the same time, and attempting to do so might suggest that they lack focus and aren't really that committed to any one thing. Also, it would be very difficult for someone to do all of these things simultaneously (e.g. running a small business while deployed in Iraq), so the person might come across as lying in order to impress people.&lt;br /&gt;
|-&lt;br /&gt;
|'''I will lead the fight''' against the big banks, special interests, the Earth's climate, and our children. I…&lt;br /&gt;
|This is another populist message listing off hot button topics. However, after starting out with some typical promises to fight fairly commonly despised things, it then becomes more controversial. It promises to fight the climate, with the peculiar implication that damaging the climate is the goal, and 'our children', which most voters would think would need protecting. This may be suggesting that politicians using these kind of messages are likely to be hiding bad intentions behind their attractive sounding slogans (or they may be just trying and failing to write a populist message without fully understanding it). The fight &amp;quot;against our children&amp;quot; may be a reference to a popular {{w|Bushism}}.&lt;br /&gt;
|-&lt;br /&gt;
|'''Wow.''' Have you seen this video of the squirrel obstacle course? Incredible! Anyway, I'm running because I…&lt;br /&gt;

Where is the hand on the harpstring, and the red fire glowing? &amp;lt;br /&amp;gt;&lt;br /&gt;
Where is the spring and the harvest and the tall corn growing? &amp;lt;br /&amp;gt;&lt;br /&gt;
They have passed like rain on the mountain, like a wind in the meadow; &amp;lt;br /&amp;gt;&lt;br /&gt;
The days have gone down in the West behind the hills into shadow. &amp;lt;br /&amp;gt;&lt;br /&gt;
Who shall gather the smoke of the dead wood burning, &amp;lt;br /&amp;gt;&lt;br /&gt;
Or behold the flowing years from the Sea returning?&lt;br /&gt;

|The opening line is designed to sound like spam for an {{W | Advance-fee scam}}. These scams typically involve impersonating someone rich, often a Nigerian prince, who claims to be in trouble and promises to share a large sum of money if the victim helps him by sending a small fee in advance. However, the second sentence of this email switches to sounding like a political fundraising email instead of an outright scam. This is either to establish a degrading comparison between flagrant scams and fundraising emails, or just to create a bait-and-switch joke. Another possibility is that the email sounds like it is a scam because it is a scam.&lt;br /&gt;
Note that a current Nigerian prince could not run for Congress. Congressional candidates must be citizens of the United States, and gaining US citizenship requires one to &amp;quot;renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which [they] have heretofore been a subject or citizen&amp;quot;.[https://www.ecfr.gov/current/title-8 (citation)]&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BLOOD FOR THE BLOOD GOD- Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This is a scatter plot comparing how good an idea sounds to how good the idea is. For example, leaded gasoline sounded like a good idea due to its anti-knocking effects, but is a bad idea due to lead toxicity. Fake prank fire extinguishers both sound bad and ''are'' bad, as they can make a dangerous situation worse. Putting mold on infections sounds like a bad idea, but some molds, like ones containing penicillin, have helpful antibiotic effects.&lt;br /&gt;
&lt;br /&gt;
The title text combines leaded gasoline and a fake prank fire extinguisher into something worse than either. The fire extinguisher is fake and releases flammable material onto the fire, and there is additional lead toxicity.&lt;br /&gt;
&lt;br /&gt;
===Table of the entries===&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! Idea !! What it means !! How good it sounds !! How good it actually is !! Explanation&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Leaded gasoline}}||Adding {{w|Tetraethyllead|tetraethyl lead}} as an antiknocking agent to allow for increased performance||++||---||Leaded gasoline was introduced in the early 1920s to allow higher pressures and temperatures in an engine without causing {{w|Engine_knocking|detonation (knocking)}}, allowing for increased fuel efficiency and engine performance; it also works to prevent engine valve wear. In essence, it artificially raises the {{w|octane rating}} of the fuel, reducing the need for fuel refinement, thus reducing waste and/or expense. Lead, however, is both toxic and bioaccumulative, meaning that lead released into the air over decades built up to harmful levels in people (as well as other animals) and almost certainly contributed to a host of health issues. Some scientists even suppose that {{w|Lead–crime hypothesis|crime levels are influenced by lead exposure}}. (It should be noted that this only &amp;quot;[sounded] like a good idea&amp;quot; due to deliberate campaigns to obscure the known dangers). &lt;br /&gt;
|-&lt;br /&gt;
|{{w|Bloodletting}}||Releasing &amp;quot;bad blood&amp;quot; from the veins||---||---||You need (most of) your blood. Losing [https://www.ncbi.nlm.nih.gov/books/NBK542273/ more than 15%] of a person's total blood volume results in adverse effects. Bloodletting has been performed as a medical procedure for at least 2000 years until the 19th century. The idea was to withdraw blood to balance the body's &amp;quot;humors&amp;quot;. Despite this long history, the notion that bleeding someone is bad seems like basic common sense, and it's now well-understood that blood-letting (outside of {{what if|98|certain rare and specific cases}}) does no good, causes significant harm and quite certainly causes many deaths when it is used.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Asbestos}}||Mineral which does not burn, tolerates extremely high temperatures and forms small fibers. These qualities make it excellent for insulation and fire protection||+++||---||Asbestos was used extensively in ships and buildings throughout most of the 20th century. Unfortunately, the microscopic fibers that make up asbestos greatly increase the risk of {{w|Asbestosis|lung disease}} and cancer when inhaled, causing its use to be banned in most countries.&lt;br /&gt;
|-&lt;br /&gt;
|Extension cords with prongs on both ends||allows easy connection between 2 female connectors||0 (neutral)||---||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video].&lt;br /&gt;
|-&lt;br /&gt;
|Stair kayaking||Riding down a flight of stairs in a {{w|kayak}}||--||---|| Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, [https://youtu.be/46BjHAxgddU?t=154 rides the kayak down the stairs]. This poses significant easily foreseeable risks of injury or death, as well as being very bad for the kayak, which is designed to ride on {{w|Kayak|water}}, not stairs.{{Citation needed}}&lt;br /&gt;
|-&lt;br /&gt;
|Fake prank fire extinguishers||Intentionally placing empty or otherwise non-functional {{w|fire extinguisher|fire extinguishers}} as a {{w|practical joke}}.||---||---|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds very dangerous and potentially life-threatening for many people, and it would be highly dangerous. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].&lt;br /&gt;
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.&lt;br /&gt;
|-&lt;br /&gt;
|Always saying what you think||...regardless of the feelings of others or other considerations||++||--||Openness and honesty are seen as positive character traits in people. However, taking it to the extreme of ''always'' telling people what you think about them, can lead to awkward or unpleasant situations. It may harm your relationship with the other person if they don't like what you think, or they may reply without concern for ''your'' feelings or other considerations. Keeping negative thoughts to yourself or telling &amp;quot;white lies&amp;quot; can be considered a better alternative in some situations.&lt;br /&gt;
|-&lt;br /&gt;
|Replying to spammers||Clicking on the &amp;quot;Reply&amp;quot; button from {{w|spam email}}s and writing (and sending) a reply (or worse, clicking on the links in these emails)||--||--||At best, you confirm your email address and identify yourself as someone likely to respond to such unsolicited messages and so encourage the spammers to deluge you with even more messages. At worst, the spammer may use your correspondence to extract sensitive information about you or make you a victim of a scam.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Solar car}}s||Having {{w|Solar panel|solar panels}} on the car's surface (mostly hood and roof) for power generation||+++||-||Powering electric vehicles with solar panels seems like an excellent idea: it would provide free power with no increased land use, and theoretically could allow a vehicle to operate indefinitely without being fueled or charged. However, such vehicles couldn't operate without batteries (due to power requirements, weather conditions, shade from roadside features and nighttime driving), so they'd have increased complexity compared to plug-in or hybrid cars. Adding solar panels would add cost, weight, manufacturing complexity and maintenance requirements. Solar panels on moving cars are less efficient than in stationary installations and subject to damage from both collisions and road debris; even without these problems, the size of automobiles relative to their power requirements would sharply limit the car's range (unless it was a normal electric vehicle with supplemental solar panels). Solar cars do exist (the {{w|World Solar Challenge}} is a competition for such cars), but as a practical form of transportation, the negatives likely outweigh the positives.&lt;br /&gt;
|-&lt;br /&gt;
|Heelies||{{w|Heelys}} are shoes with an inline skate wheel embedded in the sole, at the heel. ||+||-||Heelys allow the wearer (usually children) to shift between normal walking and rolling like being on skates. This sounds like fun but  [https://abcnews.go.com/Health/Exercise/story?id=3242181&amp;amp;page=1 has been suggested] to be a potentially significant injury risk.&lt;br /&gt;
|-&lt;br /&gt;
|Prequels||A work of fiction (mostly movie) telling the &amp;quot;story before the story&amp;quot; of another work of fiction.||+++||-||More of a good story sounds great on the surface, and audiences who are invested in a set of characters and/or a setting often love the idea of finding out what led up to certain events. But there are several pitfalls. Any spin-off of a popular property risks becoming a low-quality cash grab. Prequels, specifically, are constrained by the fact that they have to lead to the story that's already been released, which can lead to contrived storytelling. There's less room for suspense since the future of the storyline has already been established. There's a tendency to invent or fill in detailed backstories, which can undermine character arcs, and/or destroy the mystery and nuance of certain characters. And, since they tend only to be made where the original is already well-received, regression to the mean tends to mean they are more likely than not to fail to live up to expectations. Prequels can be good, of course, but there are a lot of ways they can go wrong.  &lt;br /&gt;
|-&lt;br /&gt;
|Transitions&amp;amp;#174; lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses, which get darker (like sunglasses) in bright light.||+||-||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the exposure is removed. The advantage is that wearers of glasses don't need to buy separate (prescription) sunglasses. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, perhaps in a forest or when driving. If used in a car, the windscreen filters out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark, and in cold weather they might stay dark for too long.&lt;br /&gt;
&lt;br /&gt;
Additionally, the following should be considered. UV-conscious people protect their face against UV light, so the skin doesn't form wrinkles and ages slower. Sunscreen is difficult to apply around eyes without getting the substance on eyeballs (cosmetic substances should not get there). One of the reasons behind wearing sunglasses may be to protect skin around eyes from forming so called {{w|wrinkle|crow's feet}}. Under UV-filtering sunglasses, UV-activated transitions contact lenses will not darken defeating their purpose. At the same time transitions contacts are typically at least twice as expensive as the regular ones.&lt;br /&gt;
|-&lt;br /&gt;
|Cutting pizza in squares||Cutting (a presumably round) pizza in squares||-||-||Most people cut pizza into wedges and hold it by the crust. Cutting it into squares could allow for more pieces to be shared, if the resulting wedges would be too thin to be practical. However, pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. Cuts around the edge will probably leave smaller leftover scraps which are mostly crust. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only into four squares, some people will end up with a higher crust-to-topping ratio than others. Cutting a round pizza into squares is popular in Chicago and is sometimes called tavern-style or party-cut and some&amp;lt;sup&amp;gt;&amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;''{{w|Wikipedia:Manual_of_Style/Words_to_watch#Unsupported_attributions|who?}}''&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;&amp;lt;/sup&amp;gt; consider it the real Chicago style pizza rather than deep dish pizza.{{Dubious}}&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Project Orion (nuclear propulsion)|Project Orion}}||Study by the U.S. government looking into nuclear pulse propulsion for spacecraft.||---||-||Using repeated nuclear explosions to generate motion sounds bad for both the spacecraft and everything else, especially with a ground launch, but there are ways to address a lot of the concerns, so it isn't as bad as it sounds. Project Orion's theorized specific impulse and thrust would also be far higher than anything chemical rockets can accomplish. The efficiency of Project Orion is extremely low, however, and the {{w|ablation}} issues are extremely difficult to overcome.&lt;br /&gt;
&lt;br /&gt;

|Soup||{{w|Soup}}||0 (neutral)||0 (neutral)||Soup is probably one of the oldest foods created by prehistoric cooks. Many people enjoy it, though some consider many soups somewhat lacking as a meal on their own, or boring.&lt;br /&gt;
|-&lt;br /&gt;
|Combo washer dryers||A device that combines washing machine and laundry dryer into one device||+++||+||Better at space efficiency, but worse at each task than separate devices, and unable to do both tasks in parallel (useful when you have more than one batch of laundry).&lt;br /&gt;
|-&lt;br /&gt;
|Cutting sandwiches diagonally||Cutting sandwiches diagonally||+||+||[https://www.popularmechanics.com/science/math/a32690399/triangles-rectangles-best-way-cut-sandwich-math/ Generally] [https://www.npr.org/2009/11/28/120914097/rectangles-vs-triangles-the-great-sandwich-debate regarded] as the superior way to slice a sandwich, providing more aesthetically pleasing display of the contents, better support in the hand and fewer all-crust bites. Required in the assembly of a club sandwich,{{actual citation needed}} where the diagonal components are stacked again.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Diverging diamond interchange}}s||Road junction where the two (sets of) lanes cross over to switch sides (so if you normally drive on the right, now you drive on the left), then switch back to normal after the junction||-||+||Highway engineers believe the shape improves safety and traffic flow through the interchange because switching to the other side facilitates merging to and from the other road in the junction. However, the shape appears to be insanity to an unfamiliar driver.&lt;br /&gt;
|-&lt;br /&gt;
|Toasting sandwiches||Making a sandwich first and then cooking it, as in a dedicated {{w|Pie_iron|sandwich toaster}}, a {{w|toaster oven|toaster oven}}, frying pan or under a grill.||++||++||The grilled cheese sandwich is a familiar form to most people, and many other sandwiches are improved by toasting as a final step. Others, such as the {{w|western sandwich|Western}} or {{w|club sandwich|club}} are prepared using toast. The {{w|peanut butter, banana and bacon sandwich|Elvis}} is a specific case of a sandwich that normally wouldn't be toasted, but is improved by it - peanut butter, bacon, banana, and jelly, with the assembly lightly fried.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Crumple zone}}s||Designated areas of a car that crumple in case of a crash. ||--||++||Most people's intuition would be that stronger cars are safer, and intending parts of a vehicle to collapse ''by design'' might seem crazy. But engineered crumple zones are designed to absorb the kinetic energy in a vehicle collision, and do so in such a way as to protect the integrity of the passenger cabin. The result is that the occupants experience less intense deceleration and ideally without the damage significantly compressing the shell around them. This significantly reduces the danger of injury or death from crashes. &lt;br /&gt;
|-&lt;br /&gt;
|{{w|Sliced bread}}||Bread, sliced by the baker before packaging for sale||+++||++||It's far more convenient for making sandwiches or toast, but unfortunately pre-sliced bread will go stale faster and some applications may be better off thicker or thinner than the slices provided. Sliced bread is often used as a comparator for how good something is, using the phrase 'the best thing since sliced bread'.&lt;br /&gt;
|-&lt;br /&gt;
|Pizza||{{w|Pizza}}||++||++||Pizza is a widely popular dish throughout much of the world, uncontroversial {{w|Anchovies_as_food|except}} {{w|Pineapple|certain}} [https://www.taste.com.au/recipes/nutty-choc-pizza-fresh-berries/2c0220a4-8463-45ff-b2ba-ac7e5012a006 toppings].&lt;br /&gt;
|-&lt;br /&gt;
|Eating citrus fruit while at sea||Having a supply of {{w|citrus fruit}} on long sea journeys, especially during the {{w|Age of Sail}} ||0 (neutral)||+++||For a long time, {{w|Scurvy|scurvy}} was a danger to sailors, who generally subsisted on a monotonous diet of shelf-stable foods with low vitamin content while on long voyages. Most citrus fruits are rich in vitamin C, which prevents scurvy. Eating orange or lemons doesn't seem like a significant activity one way or the other, but it's an easy way to prevent a disease that causes serious ill-health and possibly a painful death.  &lt;br /&gt;
|-&lt;br /&gt;
|Putting mold on infections||Seemingly a reference to the ancient practice of pressing moldy bread against infected wounds||---||++||While this sounds like a good way to get a fungal infection, with the correct mold this is a primitive way to obtain an antibiotic. Certain fungi naturally produce antibiotic substances, and this is where humans discovered {{w|penicillin}}.&lt;br /&gt;
|-&lt;br /&gt;
|Wheels on luggage||Some luggage bags have small wheels inset on their frame and a carrying handle.||+++||+++||A relatively simple fitting for rigid or semi-rigid luggage that substantially eases its transport over long distances on flat surfaces such as travel terminals.&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Heat pump}}s||A technology that moves heat energy from a cold area to a warm area, most familiar as the technology that keeps a refrigerator cold. It can be used to heat a home interior in winter or cool it in summer.||++||+++||Unlike traditional furnaces, heat pumps do not generate heat (beyond a small overhead). Instead, they move existing thermal energy from a coolable environment across to a warmable one. This allows a space to be heated with significantly less energy use than a furnace or resistance heater that just generates heat 'from scratch'. Because these units are operated by electricity, they can provide heating with renewable energy (potentially using {{w|thermal energy storage}} for load-shifting), reduce or eliminate the need for natural gas connections, and prevent several risks that come with traditional furnaces (such a carbon monoxide leaks and fires). In addition, heat pumps can operate in the reverse direction as air conditioners, so a single unit can be designed to both heat and cool a building. It sounds like a good idea and works out pretty well in real life.&lt;br /&gt;
&lt;br /&gt;

|-&lt;br /&gt;
|{{w|Laser eye surgery}}||Surgical techniques using lasers for precision cutting in the eyeball.||-||+++||In the popular imagination, lasers are often thought of as something used for destroying their target. Firing them into people's eyes, then, does not sound like a great idea. However. this technology has substantially improved the eyesight of millions of people worldwide by allowing the treatment of eye problems otherwise only corrected by lenses or entirely untreatable. Randall has previously commented on laser eye surgery, amongst other ideas both good and bad, in [[1681: Laser Products]].&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Fecal transplant}}s||Transfer of the gut microbiome of a healthy person to the sterilized gut of an ill person.||---||+++||The gut microbiome is a collection of bacteria that lives in our guts. It can influence our health. It is responsible for the last stages of digesting our food. It can also produce neurotransmitters that are carried by blood to our brain influencing our behavior. A healthy microbiome can be destroyed by bad eating habits, unhealthy lifestyles, acquired infections or the use of antibiotics. The important part is the composition of different species of bacteria that compromise the biome. Sometimes it may be necessary to completely sterilize the gut and then take a sample of a healthy biome from another person. A sample is enough as the bacteria will multiply. As long as the patient eats correctly, the microbiome after transplant should develop correctly.&lt;br /&gt;
&lt;br /&gt;
It sounds bad because we tend to think of our feces as something gross, to be discarded, and other people's bacteria as infectious. It is called fecal transplant as our feces contain about 50% of gut bacteria, but nowadays the sample usually takes the form of a coated pill that is applied rectally.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by A BOT ASKING BAD TRIVIA QUESTIONS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Many pubs have {{w|pub trivia|trivia nights}}, where patrons form teams and compete to answer questions about a range of topics. The typical goal for trivia games is that they be challenging, yet possible, and so the questions whose answers are too difficult or too easy generally make for a poor game. In addition, it's usually preferable that questions are clearly worded with a single, objective answer, so as to avoid disputes about which answers are correct.&lt;br /&gt;
&lt;br /&gt;
Cueball has apparently been hired by one bar to infiltrate ''other'' bars' quiz nights and ask particularly bad questions. The implication is that this will make the games unpleasant, in the hopes that people will leave, and possibly go to the bar that hired Cueball. &lt;br /&gt;
&lt;br /&gt;
Cueball uses a variety of strategies to write bad questions, including questions that are trivial (where the answer is painfully obvious), unanswerable (either because there is no answer, or because the answer is unknown), ambiguously worded or arguable. &lt;br /&gt;
&lt;br /&gt;
Many of his questions could be altered slightly to make them more reasonable for such a game, but that would defeat Cueball's purpose. &lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! Question !! Problem with the Question !! Explanation !! More Reasonable Alternative(s)&lt;br /&gt;
|-&lt;br /&gt;
|1. Which member of {{w|BTS}} has a birthday this year?||Multiple correct answers||All people have birthdays every year{{Citation needed}} (other than pedantic exceptions due to calendar issues or timezone alterations, or someone dying before their birthday, or being born on a leap day, none of which apply in this case). Therefore, all seven members of BTS have birthdays this year.||Which member of BTS has a birthday today/this week/this month? Which member of BTS turns [a specific age] this year?&lt;br /&gt;
|-&lt;br /&gt;
|2. How many sides does a {{w|platonic solid}} have?||Multiple answers, ambiguous language||There are five {{w|Platonic solids}}, with 4, 6, 8, 12 or 20 faces (colloquially called sides) in {{w|Euclid|Euclidean}} {{w|Euclidean geometry|3-space}}. The solids have, respectively, 6, 12, 8, 30 and 30 edges (also occasionally called sides colloquially). A more devious quizmaster might actually include this as a trick question with the correct answer being 'zero', since strictly speaking solids do not have 'sides'.||How many Platonic solids are there? What is the highest number of faces on a Platonic solid? How many faces does a [specific platonic solid] have? How many faces (or edges, or vertices) do ''all'' the platonic solids have (i.e., added together)?&lt;br /&gt;
|-&lt;br /&gt;
|3. What is the smallest lake in the world?||Arguable||While the largest lakes are relatively straightforward to categorize, smaller bodies of water range in size down to individual puddles. There is no clear, definitional line at which a body goes from being a lake to a pond, for example. In addition, the size of small lakes will fluctuate due to variability in precipitation, and other weather effects, and some lakes only exist for brief periods (intermittent lakes). Hence, which small bodies of water are &amp;quot;lakes&amp;quot; and which is the smallest can't be clearly answered, without specifying a whole list of parameters and standards.||What lake has the largest surface area in the world? What is the world's deepest lake? What lake is recognized by the Guinness World Records as the world's smallest? (Benxi Lake in China).&lt;br /&gt;
|-&lt;br /&gt;
|4. Which Steven Spielberg movie features more shark attacks, {{w|Jaws (movie)|Jaws (1975)}} or {{w|Lincoln (movie)|Lincoln (2012)}}?||Trivial||''Jaws'' is a famous movie about a killer shark, and features at least five fatal shark attacks. Lincoln is a movie about the passage of the Thirteenth Amendment to the U.S. Constitution, containing zero shark attacks.{{Citation needed}} Anyone with even a passing familiarity with American popular culture should be able to get this one right, and someone with no knowledge could likely guess the answer from the titles alone. This might be mistaken for a silly trick question, as ''Lincoln'' is a much less famous movie.||How many times is a shark seen on screen in &amp;quot;Jaws&amp;quot;? Which film won more {{w|Academy Awards}}? How many fatal shark attacks occur in &amp;quot;Jaws&amp;quot;?&lt;br /&gt;
|-&lt;br /&gt;
|5. How many planets were there originally?||Ambiguous||The question doesn't specify a time frame or culture. It could be referring to the original meaning of the word, derived from the Greek planḗtai, meaning &amp;quot;wanderers&amp;quot;, which in antiquity referred to the Sun, Moon, and five points of light visible by the naked eye that moved across the background of the stars — namely Mercury, Venus, Mars, Jupiter and Saturn. It could also be referring to the meaning of the word prior to the International Astronomical Union (IAU) adopting an official definition of the term &amp;quot;planet&amp;quot; in 2006, which demoted Pluto to a dwarf planet. It also doesn't specify that it's referring to planets in our solar system alone (in the observable universe there are almost certainly trillions of planets). Additionally, it asks how many &amp;quot;were there&amp;quot;, as opposed to how many planets &amp;quot;were known&amp;quot; (the number which we know of being far smaller than the true number of planets in the universe).  The word &amp;quot;originally&amp;quot; could also imply the origin of the solar system, or the origin of the universe, in which case the answer would be 'zero' as no planets had yet accreted.||How many planets were known to Ancient Greece? How many planets were known to science prior to the invention of the telescope? How many planets were in our Solar System at the end of the 20th century?&lt;br /&gt;
|-&lt;br /&gt;
|6. What {{w|NFL}} player has scored the most points outside of a game?||Ambiguous, Unknowable||The term &amp;quot;scored the most points&amp;quot; generally only applies within the context of a game, making it very unclear what kind of &amp;quot;points&amp;quot; the question is referring to. Does it mean points in non-NFL games? Points in games other than football? Points outside the context of any game at all (such as 'making a point' in conversation)? Even if this were clarified, points scored in official games in professional sports leagues are meticulously recorded and published, points scored in any other context are not, so the question is likely impossible to answer. Arguably, Brian Jordan would be an answer, with 121 Minor League and 755 MLB runs scored (points).||Which NFL player scored the most points in a game/season/career?   &lt;br /&gt;
|-&lt;br /&gt;
|7. The {{w|Wright brothers}} built the first airplane. Who built the last one?||Unknowable||Orville and Wilbur Wright are widely credited with designing and building the first airplane (in the sense of a heavier-than-air flying machine that could take off, steer and land under its own power&amp;lt;!--  - if such a machine should count as an airplane proper remains a controversial subject, taking into consideration the machine created 3 years later by brazilian inventor ''Alberto Santos Dumont'' which falls more in line with what an airplane is expected to be - whether he or the brothers were more deserving of credit for this achievement is debated to this day especially in Brazil, Dumont's country of origin NOT SURE WHAT MAKES THE WRIGHT FLYER LESS OF A PLANE THAN 14-BIS; THE LATTER WORKED, IS WORTHY OF RECOGNITION, BUT THEY BOTH FLEW AND THE FORMER STILL FLEW FIRST --&amp;gt;). In modern times, design and construction of airplanes has become a huge, international industry, with many airplanes of widely varying sizings being built each year. Since airplanes are built continuously, which one was made most recently depends on when the question is asked (and would be very difficult for the average person to know -- and not trivial for even a member of the aerospace industry to know). If it's asking about the last airplane ''ever'', that's impossible to know, since that plane hasn't been built yet (and hopefully won't for a very long time).||Who built the first airplane '''after''' the Wright brothers?  When was the final Wright Model B aircraft built?&lt;br /&gt;
|-&lt;br /&gt;
|8. Is every even number greater than 2 the sum of two primes?||Unknown, Possibly unknowable||This is a famous, centuries-old {{w|open question}} in math known as {{w|Goldbach's conjecture}}. Mathematicians widely believe that it is true, and it has held true for every number checked up to 4 ⋅ 10&amp;lt;sup&amp;gt;18&amp;lt;/sup&amp;gt;, but since it's impossible to check every number, we can't assume it's universally true. No mathematical proof of its veracity exists at this point. Since it is {{w|Gödel's incompleteness theorems|known}} that something can be true but impossible to prove (and, being true, impossible to disprove), this may be the situation forever.||According to which mathematical conjecture is every even number greater than 2 the sum of two primes?&lt;br /&gt;
|-&lt;br /&gt;
|9. Not counting {{w|Canberra}}, what city is the capital of {{w|Australia}}?||No answer exists||Australia has only one capital (unlike some countries, which divide the legislative and administrative capitals, for example), and that capital is Canberra. Hence, by definition, there is no national capital &amp;quot;not counting Canberra&amp;quot;. Though each constituent state also has its state capital (inclusive of Canberra, which is the entirety of its {{w|Australian Capital Territory|own state territory}}), this would still leave us with an ambiguous choice. Before 1927, the answer could be Melbourne, as that was where the Parliament sat at that time. ||What city is the capital of Australia?  What is currently the largest city in Australia? What is the smallest state capital in Australia? Not counting Canberra, what city was the most recently founded state capital of Australia? What city was the capital city before Canberra?&lt;br /&gt;
|-&lt;br /&gt;
|10. Who played the drums?||Trivial, yet unknowable without context||As worded, the question could be answered with anyone who's ever played the drums, in any context, whether professional or not, in all of history. This would include a huge number of people, most of whom would not be well-known. Most people would be able to offer a technically correct answer, and almost none of them would be interesting.  Or maybe the host is wondering who it was that played drums that night, as part of the bar's live music.||Who played the drums for some specific band/album/track/concert?&lt;br /&gt;
|-&lt;br /&gt;
|(Title text) Where is {{w|London}} located? (a) the {{w|British Isles}} (b) {{w|Great Britain and Northern Ireland}} (c) the {{w|United Kingdom|UK}} (d) {{w|Europe}} (or 'the {{w|European Union|EU}}') (e) {{w|Greater London}}||Multiple answers||All choices are technically correct as they are various geographical areas that include the city of London, England. Also note that the City of London is different from the city ''named'' London, as the latter includes a large region around the former, hence (e) as an answer. Answer (d) is both correct and incorrect, as it conflates a geographic region, Europe, and a political body, the European Union. The United Kingdom (and therefore London) {{w|Brexit|left the EU}} in 2020, but is still geographically included in Europe. This also does not get into cities named London outside of the UK, so for example &amp;quot;Ontario&amp;quot; or &amp;quot;Canada&amp;quot; could also be possible answers if the test designer were truly evil, thus making none of the answers correct. ||What is the capital of the United Kingdom? (answer: London)&amp;lt;br&amp;gt;Where is London, England '''not''' located? (a) the British Isles (b) Great Britain and Northern Ireland (c) the UK (d) Europe (e) the EU (answer: (e))&lt;br /&gt;
