}}

==Explanation==
This was the second comic with one of [[Randall|Randall's]] [[:Category:Fun fact|fun facts]].

This comic is a joke on the phrase "Shit just got real", which means "something has suddenly increased in difficulty and become genuinely challenging or dangerous".

[[Cueball]] is standing in front of a board delivering a lesson, and is about to multiply a wavefunction by its complex conjugate. A {{w|wave function}} is a mathematical description of a quantum system which uses {{w|complex number|complex}} values - numbers that have both a {{w|real number|real}} part and an {{w|imaginary number|imaginary}} part. Multiplying a wavefunction by its complex conjugate is a common thing to do, as it yields the probability density of where a particle is likely to be found, which is a real-valued function.

Complex numbers can be written in the form a + bi, where a is the real part and bi is the imaginary part. i is the imaginary unit, defined so that i² = -1. The {{w|complex conjugate}} of a complex number simply reverses the sign on the imaginary part - so for the number above, the complex conjugate is a - bi.

Multiplying the complex number by its own complex conjugate therefore yields (a + bi)(a - bi). If you multiply out the brackets, you get a² + abi - abi - b²i². The abi cancel each other out, and i² can be replaced by -1. Thus, the result is a² + b², a real number, so "shit just got real" as Cueball promised.

The title text notes that you can make this joke in class every time a calculation is performed that drops the imaginary part from a complex number, but warns that it would be so annoying that the professor will eventually find a way to have the class without you in it. Because nonreal numbers are often considered to have no physical significance, turning them into real numbers to produce a final answer is so common that this joke would quickly become tedious.

The wave function shown on Cueball's board is the {{w|Schrödinger_equation|time-dependent Schrödinger equation}} <math>i\hbar\dfrac{\partial}{\partial t} = \hat{H}\Psi</math>, a {{w|Differential equation|differential equation}} that the {{w|Wavefunction|wavefunction}} Ψ, which determines the possible positions of a quantum particle over time, always satisfies. The {{w|Derivative#Partial_derivatives|derivative}} should be written with ∂Ψ on the top; the omission of the Ψ may be a mistake.

==Transcript==
:[Cueball, holding a marker pen down in one hand, is standing at a whiteboard with two equations, one of which is the time-dependent Schrodinger equation and the other shows what the wavefunction equals, but from there it becomes unreadable. Below is a graph with a bell-shaped curve. There are also other unreadable markings on the board below the second equation and next to the graph.]
:Cueball: Okay, anyone who's feeling like they can't handle the physics here should probably just leave now.

:[In a frame-less panel Cueball is seen writing on the whiteboard. This is seen from the side of the board, so it is just a thin line with a shelf at the bottom for putting the pen on.]
:Cueball: Because I'm multiplying the wavefunction by its complex conjugate.
:Cueball: That's right.

:[Dramatic zoom in on Cueball appears to be writing the final part of his next equation.]
:Cueball: Shit just got ''real''.

2978: Stranded

172.69.43.227: /* Explanation */

==Explanation==
{{incomplete|Created by a TWO ASTRONAUTS THAT ARE ABSOLUTELY NOT STRANDED NOSIREEBOB - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic is making fun of the {{w|Boeing Starliner}}, which launched for its Crewed Flight Test on June 5th, 2024. The mission to the {{w|International Space Station}} was originally scheduled for only eight days, but as of the comic’s release (Aug 28, 2024) the astronauts, Butch Wilmore and Suni Williams, are still "stranded" on the ISS.

The comic points out that being stranded is a matter of perspective and circumstances; people on Earth could equally be considered "stranded", unable to get off the planet. Many science fiction stories deal with some sort of rush to evacuate the Earth, though there's usually a reason why they would wish to leave, a reason that's notably absent in the comic. Moreover, the proposed solution of one rocket would not be able to bring all 8 billion people on Earth to space.{{cn}}

The comic is also making fun of the fact that during press conferences, NASA has stressed that the Starliner astronauts are not actually stranded, because there are procedures for emergency returns to Earth, yet they're not expected to return until February 2025, on a {{w|SpaceX Crew_Dragon}}.

The title text references commentators saying that at least the Starliner crew aren't alone up there, as there are currently nine people aboard the ISS, but flips it around to be about the (8 billion) people on Earth.

==Transcript==
:[Two astronauts, Megan and Cueball, are shown floating in the cabin of a space station, Megan near the top and Cueball near the bottom. Various devices are visible attached to the walls of the space station. There's an elliptical window through which they can see some of Earths surface. Three white shapes that could represent continents between water or else represent clouds are visible.]
:Megan: Until they get another rocket ready to launch, 8 billion people are stranded down there.

2971: Celestial Event

==Explanation==
{{incomplete|Created by a CURSED SHOP THAT APPEARS EVERY FOUR POINT THREE BILLION YEARS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic highlights the extreme rarity of witnessing multiple special events—{{w|aurora}}s, {{w|Solar_eclipse#Total_eclipse|total solar eclipses}}, {{w|Great_Comet|great comets}}, and {{w|Periodical cicadas|17-year cicada emergences}}—all occurring simultaneously in the same location. It calculates that such an event would happen only once every 4.3 billion years, a time span comparable to the age of the Earth. The comic was posted shortly after some people reported seeing auroras in conjunction with the {{w|Perseids meteor shower}}.[https://www.msn.com/en-us/weather/topstories/the-2024-perseid-meteor-shower-and-northern-lights-overlapped-in-a-rare-cosmic-display-see-photos-of-the-dazzling-event/ar-AA1oJKKC] [[Randall]] also includes a 50% chance of clear skies, which further reduces the odds of witnessing all events together. The comic exaggerates the difficulty of this happening, emphasizing that these conditions align less often than Earth's lifespan, suggesting such a celestial spectacle might only occur once before Earth becomes uninhabitable.

The calculation assumes that these events occur independently and that their probabilities remain constant over time, leading to the improbable result. However, this is a simplification, as factors like orbital mechanics and atmospheric conditions are not entirely random, whereas others, such as the amount of cloud cover and the existence of cicadas, may change unpredictably over time.

The title text humorously suggests using 13-year cicadas instead of 17-year ones to improve the odds, reducing the interval to 3.29 billion years. This idea, along with the possibility of weather manipulation, reflects Randall's satirical take on humanity's desire to control or predict natural phenomena, even when the timescales involved are beyond human comprehension. Earth's oceans may evaporate in about a billion years [https://www.sciencedaily.com/releases/2013/12/131216142310.htm], adding a layer of urgency and humor to the idea of witnessing this "super-event" before life on Earth ceases to exist.

Randall estimates that total solar eclipses occur once every 350 years at a given location, a value close to the 320-year interval for his hometown of Boston, Massachusetts, based on [https://eclipse.gsfc.nasa.gov/JSEX/JSEX-index.html NASA's data.]

{{incomplete|Created by a BOT THAT APPEARS EVERY FOUR POINT THREE BILLION YEARS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic multiplies the fraction of time that selected classes of celestial events occur in the sky over a particular location on the Earth's surface, in this case, Cambridge, Massachusetts, where the cartoonist was living when this comic was published. The resulting product is the expected frequency that all of them would occur at the same time at that location. The value he calculates is once every 4.3 billion years. This is in the same ballpark as the current age of the Earth, about 4.5 billion years.

The calculation itself is not going to be accurate, which is likely part of the joke. Multiplying probabilities only works for random variables that are entirely independent. If nothing else, orbits are (luckily) not random{{cn}}. It also requires that all of the probabilities remain constant over time. In reality, the likelihood of cicadas still existing after 4.3bn years is very low, and there's a good chance of a shift in the patterns of some of the other occurrences over that timespan as well.

Conversion of "days" and "months" to fractional years, required for conservation of units in the equation, is ambiguous as presented due to the leap year phenomenon and the inconsistent number of days in a month. Differing values for these fractional years yield a range of frequency solutions between 4.2 and 4.4 billion years. If the value for days in a year is given as 365.25 (the mean value for all years, ignoring infrequent additional 'leap year' corrections), as in the first term of the equation ((20/365.25)/11), and the mean value for days in two months is given as 60.9 as in the second term ((60.9/365.25)/50), the result is 4.2995 *10^9 years.

2970: Meteor Shower PSA

2024-08-12T10:42:24Z

172.69.43.227: /* Explanation */

{{comic
| number = 2970
| date = August 9, 2024
| title = Meteor Shower PSA
| image = meteor_shower_psa_2x.png
| imagesize = 561x272px
| noexpand = true
| titletext = If you hold the meteor too long, it may imprint on you and form a contact binary, making reintroduction to space difficult.
}}

==Explanation==
{{incomplete|Created by a REHABILITATED BOT ABOUT TO BE RELEASED BACK INTO THE WILD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic is a {{w|public service announcement}} (PSA) regarding what to do in case you discover a {{w|meteorite}} from the upcoming {{w|Perseid}} {{w|meteor shower}}. (See here regarding [[1723: Meteorite Identification]]).

In the first panel of the comic [[Cueball]] discovers a {{w|meteorite}} on the ground from the {{w|Perseids}} meteor shower. He then proceeds to try and throw it into space again. This is of course not possible, but this is not the reason why this action is marked as wrong with an X.

Rather, the PSA claims, in the next panel, that what he should do is contact, and then deliver the meteorite to, an observatory where astronomical "rehabbers", like [[Ponytail]], will care for it, and hopefully release it back into the wild with the next space launch. This is marked with a check mark to show that this is the correct procedure to save meteorites.

This conflates meteoroids that have fallen to the Earth from the sky with baby animals separated from their parents, and in need of rehabilitation (especially baby birds that have fallen from their nests, though more often in trees rather than "the sky"). If you find a sick, injured, or orphaned wild animal, your best bet is to find a nearby wildlife rehabilitator to care for it and return it to the wild, as members of the public will rarely have the same knowledge and expertise as someone who has the training and experience. However, this advice does not apply to meteors.

The title text says that if you handle the meteor too long you'll form a {{w|contact binary (small Solar System body)|contact binary}}, which in this context is two space rocks lumped together. A contact binary is also a type of binary star system, but it's unlikely that a person and a rock will form this.{{cn}} In the process of rehabilitating young animals, preventing imprinting is important as the animal cannot rely on the human caregiver to succeed in the wild (in either sense). Also, while it may be possible to return the animal to its parents, inadvertent disturbance caused in the process may cause the parents to abandon the young.

[[1475: Technically|Technically]], [[Randall]] has the terminology wrong. "Meteor" refers to the shooting star you see in the sky when a meteoroid enters the atmosphere. If it makes it to the ground, the piece that survives is called a "meteorite" (although some call it [[1405: Meteor|magma]]). But this may just be part of the "lost baby bird" analogy, in that (as a meteor, just like the chicks of birds that don't practice {{w|Bird nest#Type|some variation of ground-nesting}}) an 'actual meteor' should never have been found on the ground in the first place.

If you find a recently fallen meteor(ite), or a {{w|Meteor air burst|surviving fragment}} of one, do not touch it since it may be ''very cold''. Although the surface of the meteor will have been {{w|Aerodynamic heating|heated by the atmosphere}}, the interior will still be about as cold as space and quickly cool whatever surface was not already ablated or lost. The size/fragmentation and time it has lain on the ground will dictate how cold it is, unless it was {{w|Impact crater#Impact craters on Earth|big enough}} to release enough further heat from the {{w|Lithobraking|impact}} itself.

A more important reason, from the perspective of experts who would wish to study your find (rather than 'return it to the sky'), is that handling it directly may contaminate it more than necessary. (Or, in the case of {{tvtropes|GreenRocks|more dangerous examples}}, it could contaminate ''you''!)

2969: Vice President First Names

==Explanation==
{{incomplete|Created by CORNELIUS LYSANDER THROCKMORTON "BOT" BOTTINGFORD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Randall observes that American {{w|Vice President of the United States|Vice Presidents}} since the 80s have almost all went by short first names. It should be noted that all of the "short" first names in this strip, with the exception of John (F. Kennedy) are diminutives (or initials) of longer names, but all represent the names which the candidates preferred and publicly used. This comic was published one day after {{w|Kamala Harris}} (who replaced Biden as presidential candidate) chose {{w|Tim Walz}} as her running mate for the {{w|2024 United States presidential election|2024 presidential election}}. Both the Republican and Democratic tickets are present for 2024, since the 2024 election had not yet concluded when this comic was made. Either party winning would match the observation.

In the comic's caption, Randall amusingly describes this as an emerging "political consensus."

While not a "political" consensus per se, the observed phenomenon is a type of consensus — reflecting a multi-decade change in US societal norms — and is not simply a random coincidence.
* There has been a national US trend toward shorter names since the 1980s and 1990s, with a rise in the popularity of baby names like Ryan, Kyle, Amy and Lisa. (The trend has continued, with even shorter names like Ava, Mia and Max becoming more common in the 2000s and 2010s.)
* This has paralleled a trend in shorter business names, with companies like Dell, Cisco and eBay before the turn of the millennium and Google, Uber and Lyft after (cf. pre-1980 businesses like AT&T, BNSF or 3M which had to convert their very long names into acronyms to adapt). Product naming also began to simplify in the late 20th century, driven by marketing strategies that favored brevity and memorability, exemplified by Apple's iconic "iMac" and "iPhone" products (again, cf. names like "Tandy 1000", "Ford F 500" or "Little Debbie's Oatmeal Creme Pies").
* All of these naming trends reflect a ''general'' societal trend toward minimalism and less formality, also seen with corporate logos, product design (Apple), clothing design (Gap), furniture design (IKEA) and web/app design.

This societal shift may explain why many politicians with given names like Albert and Richard might have preferred to go by shorter, less formal sounding, more approachable names like Al and Dick, to match the zeitgeist. James Danforth Quayle additionally used his middle name (that being another common self-naming decision; or one arising from family tradition/convenience, given that James Cline Quayle was his father), one less commonly seen than the other unabbreviated name from which "Dan" might have come.

Given that trend, it is noteworthy that Vice Presidents have generally adopted shorter names, but presidents have been less likely to do so. It's possible to create theories around this (eg, the office of President is expected to have more gravitas and formality, while the Vice President has less of an official role, and wants to be more approachable), but the size of the group is small enough that it could easily be coincidence, particularly since many of those names (such as George, Barack and Kamala) can't be easily shortened. The exception, Donald Trump (which can be shortened to Don), did not become a politician until late in life, when he was already nationally famous using his full name.

The '''title text''' amusingly suggests (1) the existence of a ScrabbleTV News channel (named after {{w|Scrabble|the word game}}) staffed with (2) political pundits who (3) report Biden's decision to end his re-election campaign as being driven by orthographic (related to the writing of words) pressure to conform to the aforementioned political consensus. Having Joe Biden as President and Kamala Harris as VP violated this pattern, but elevating Harris to the presidency and selecting a short-named running mate would restore it. In addition to Tim Walz, all of the candidates considered most likely as running mate had short first names: Josh Shapiro, Mark Kelly, Andy Beshear, Roy Cooper and Pete Buttigieg. This could also be a subtle joke about political pundits tending to give confident, inaccurate hot-takes. (Biden's decision was driven, among other things, by worsening polling, rising concerns about his age, a poor debate performance against Trump and subsequent pressure from other leading Democrats.)

This is Randall's second recent comic engaging in observational comedy about US politics and Kamala Harris, the first being [[2962: President Venn Diagram]] which was published right after she rose to the top of the Democratic ticket.

===Trivia: Other ways to shorten names===
Politicians can also use a more casual name by employing their middle name (as with {{w|Mitt Romney|Willard Mitt Romney}}). Even when they're not shortened to four or fewer letters, names can be made more casual in other ways (as with {{w|Bernie Sanders|Bernard 'Bernie' Sanders}}). As well, some politicians were commonly called by short nicknames even if they did not run under those names (Dwight 'Ike' Eisenhower).

Talk:2967: Matter

2024-08-04T20:36:30Z

172.69.43.227:

This one is a head-scratcher. Do skateboarders call "anti-" things goofy? What's the deal with that Dirac statistic? [[Special:Contributions/162.158.154.31|162.158.154.31]] 23:47, 2 August 2024 (UTC)
:It's like being a 'southpaw' boxer (or at least being able to stand the opposite way, maybe in order to flip/spin the board the opposite way from what you would end up kicking it normally).
:The Dirac thing is... well, quantum physics has various uses/restrictions upon spin (and colour, etc) that isn't really physical spin (or colour) as we know it, but sort of means a kind of particle-based rotational momentum, which has to be conserved/transfered/agree in various quantum interactions (and is a quantised state, meaning that only certain spin-values can exist in a given situation).
:Both the skateboarding and the elementary physics issues are (in their own way) rather technical matters, and I know a lot more about one than the other (but think I understand the other a lot more, from just reading up on it, than I know I actually understand the original one based on what I actually was taught). [[Special:Contributions/172.70.162.186|172.70.162.186]] 00:03, 3 August 2024 (UTC)

:Given an initial universe with equal parts matter and antimatter plus a slight asymmetry (50% + e), the mutual annihilation of matter and antimatter would leave behind a residual amount of matter proportional to the asymmetry e. In the extremely dense early universe, this annihilation would be nearly complete, ensuring that almost all antimatter and a corresponding amount of matter would be annihilated into energy, leaving an excess of matter. Thus, the observed baryon asymmetry today can be explained by this initial slight asymmetry, as even a minuscule e would result in a predominantly (anti)matter-filled universe post-annihilation.

2965: Chili Tornado Quake

2024-07-30T12:49:22Z

172.69.43.227: /* Explanation */ pipe didn't type, it seems

{{comic
| number = 2965
| date = July 29, 2024
| title = Chili Tornado Quake
| image = chili_tornado_quake_2x.png
| imagesize = 302x252px
| noexpand = true
| titletext = Buildings constructed from softer materials were damaged by chili pepper impacts to the storm's high Richter-Fujita-Scoville-Mohs hardness rating.
}}

==Explanation==
{{incomplete|Created by a SCALED GHOST PEPPER - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Cueball]], as a [[:Category:News anchor|news anchor]], is reporting from a tornado that struck a chill pepper processing plant during an earthquake.


Cueball rates the event as 55,000 on the Richter-Fujita-Scoville scale. The {{w|Richter scale}} is a historic (but still well known) logarithmic scale for rating the intensity of {{w|earthquakes}} that theoretically ranges from minus infinity to infinity, with practically relevant scores ranging from about 3 to 9.5. The {{w|Fujita scale}} is a scale for rating the intensity of damage caused by {{w|tornadoes}} which ranges from 0 to 5. The {{w|Scoville scale}} is a scale for the spiciness of {{w|chili peppers}} and can go from 0 (not at all spicy) all the way up into the millions.

As with the recent [[2950: Situation]], and occasional other comics, [[Randall]] has contrived an incident that combines multiple scenarios into an improbable whole. In this case, the purpose is to give a value to the scale of the disaster based (in some undefined way) upon the combination of the various scales that might be used to measure the individual elements.

It would seem fairly likely that the three base numbers are multiplied, as with {{w|Foot-pound (energy)|similar}} compound-unit calculations, to give the single combined measure. Given the image this is not a 5 on the tornado scale. Also since the building is still there it is not a 9 on the Richter scale. So at worst it would be 4x8 for those two. This would then leave the rest for the Scoville scale, which would give around 1700 on that scale as a minimum. The other two numbers could easily be smaller so that the Scoville number would be reaching above 3000.

In the title text it is mentioned that buildings constructed from softer materials were damaged by chili pepper impacts to the storm's high Richter-Fujita-Scoville-Mohs hardness rating. The {{w|Mohs scale}} is a scale for mineral hardness ranging from 1-10, with lower numbers being softer and higher numbers being harder. Chili peppers are strong in a spicy sense, but very soft on the Mohs scale, so if it was only the chilies that hit other buildings it would only be very very soft material that would take any damage. Of course there would also be building material hitting nearby houses, thus they would do more damage than the chili. A number, where the hardness of the materials hitting nearby buildings was taken into consideration, could have been giving, adding a fourth number to consider in the title text mentioned scale. But no number is given in the title text.

The comic [[1531: The BDLPSWDKS Effect]] also dealt with a hybrid multi-disciplinary amalgum of measurements.

==Transcript==
:[Close-up of Cueball, a news anchor, next to an image with a headline above it to the left of him. The image shows of black tornado descending from sky-cover above. It is striking a building that has been damaged near where the tornado hits. Two large chilies can be seen flying through the air in the foreground, with pieces of the building and more chilies flying off further away. Straight beneath the building and going up in the middle of it there is a crack, that divides into three inside the building. The ground is also higher to the right of the point where the crack enters the building. Cueball is speaking which is shown above the image and him.]
:Headline: Breaking news
:Cueball: A tornado that struck a chili pepper processing plant during an earthquake was rated 55,000 on the Richter-Fujita-Scoville scale.

==Trivia==
*It seems the title text is missing the word "due":
**"Buildings constructed from softer materials were damaged by chili pepper impacts '''due''' to the storm's high Richter-Fujita-Scoville-Mohs hardness rating."

for some reason I always feel nervous providing an initial transcript like I'm gonna do the format wrong but nah this transcript is pretty simple, would be hard to get it very wrong - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 04:02, 30 July 2024 (UTC)

Funnily enough, an earthquake large enough to shake the house occurred near me today! No chili peppers and definitely no tornadoes nearby, (un)fortunately. [[Special:Contributions/162.158.91.92|162.158.91.92]] 04:02, 30 July 2024 (UTC)

Wonder how the scales combine. Given that Richter and Fujita are both single digit numbers (well, Richter can go above 10, but normally only when Roland Emmerich is directing), they would be pretty meaningless in an additive scale, so I would assume multiplicative. If so, the amount of damage to the building suggests relatively mild peppers.[[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 04:11, 30 July 2024 (UTC)
:what if it's like a geometric mean or smth? that feels like it makes more sense than additive and it would also allow the average pepper involved in the incident to be ''higher'' than the 55k listed - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 04:19, 30 July 2024 (UTC)
::I believe the only method that makes sense is multiplying. Since spicy can go to 0, then 2000-3000 is probably still pretty strong for most people? Anyway, it may have been a smaller earthquake and not that big a tornado, maybe 3 and 6 then it alt least get above 3000. I have added these considerations to the explanation. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:06, 30 July 2024 (UTC)

on the current state of the trivia section, i'm pretty sure we're not supposed to have opaque links that say "here" and have some comic they go to and that the structure of the sentence should be more like "in [comic x] randal also...", but i'm too tired to phrase it out rn and not entirely sure of this either - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 08:19, 30 July 2024 (UTC)

2964: Olympic Sports

2024-07-30T08:11:31Z

172.69.43.227: /* Explanation */

{{comic
| number = 2964
| date = July 26, 2024
| title = Olympic Sports

| imagesize = 553x328px

}}

==Explanation==
{{incomplete|Created by A VERY CONCERNED OLYMPIC OFFICIAL - Provide an explanation of each sport for the convenience of those unfamiliar with some or all listed sports. Do NOT delete this tag too soon.}}

This comic was officially published on the day of the opening ceremony of the {{w|2024 Summer Olympics|2024 Paris (Summer) Olympics}}, though it actually appeared early the following day.

In this comic, [[Randall]], who has no athletic training, imagines himself participating in various Olympic events, with his degrees of failure measured in terms of their humor potential.

{| class="wikitable"
|+ Olympic sports ranked by how funny it would be if a regular person competed
! How funny !! Sport !! Reason
|-
|rowspan=5| Not that funny || {{w|Rowing}} - One or more people row a boat to a destination.|| The person would struggle to row effectively, falling out of cadence and fouling the oars of the other rowers in their boat. However, if Randall competed in the single sculls, such coordination would not be an issue, and he would likely just be much slower than the other competitors. Or fall in the water.
|-
| {{w|Fencing}} - Two contestants attempt to land hits on each other with a long fencing weapon.|| Contrary to what is often portrayed in movies, sword fights of any kind are very quick, often lasting just a few seconds. Olympic fencing matches are especially fast, and an untrained layman watching the fight would probably be unable to tell the difference between a fight between two experts and a fight in which one person had no experience, aside from that said person would lose every bout.
|-
| {{w|Weightlifting}} - Contestants lift weights, which, in the Olympics, get heavier with each round, until all but one fail to lift.|| They might just fail to lift the weights.
|-
| {{w|Golf}} - Contestants attempt to hit, with golf clubs, a golf ball into one or more holes in as small a number of hits as possible.|| They would likely miss the ball or hit poorly, due to an incorrect stance/swing when hitting, using a club whose loft (angle of the front face) is inappropriate, or just basic lack of skill.
----
''The comic illustrates this by having Randall putt and misses the hole at very close range.''
|-
| {{w|Archery}} - Using a bow and arrow, contestants attempt to hit a target with as much accuracy as possible.|| Arrows might miss the target, but it's not particularly amusing (unless Randall forgoes armbraces & discovers the bowstring's propensity for smacking the inside of his wrist after releasing it).
----
''The comic shows Randall missing all his shots on the target.''
|-
|rowspan=5| Pretty funny || {{w|Swimming}} - Contestants swim to a destination or complete lengths as fast as possible.|| They might struggle to stay afloat (particularly in open water swimming, where they would be buffeted by other contestants) or {{w|Eric Moussambani|swim awkwardly}}. They are also likely to have a markedly different physique to the other competitors, which would have a comic effect.
|-
| {{w|Long jump}} - Contestants, with a running start, attempt to jump as far as possible.|| They would likely make a very short jump, or perhaps foul every jump.
|-
| {{w|Pole vault}} - Using a bendable pole, contestants attempt to propel (vault) themselves over a bar.|| They might miss the plant and end up dropping the pole and running under the bar. If they did manage to get some lift, but failed to get enough to reach the mat, it would probably be concerning, rather than funny.
|-
| {{w|Diving}} - Contestants attempt to fulfil multiple criteria while diving into water.|| Awkward or painful-looking dives could ensue. Potential for injury would be high.
|-
| {{w|Hurdles}} - Contestants run on a track with hurdles positioned at various places.|| They might trip and fall over the hurdles, or just knock them all over as they fail to clear them.
----
''Drawn in this section, Randall repeatedly and unpleasantly runs into the hurdles, unable to jump over any of them. He has his arm raised bent in front of his face in a classic hurdler's pose, but appears to have failed to get much, if any, height off the ground.''
|-
|rowspan=5| Incredibly funny || {{w|Figure skating}} [The only Winter Olympic discipline featured in the main comic] Competitors perform artistic routines set to music while skating on an ice rink, and are judged on a combination of skating skill, composition, and presentation. || They might slip and fall continually on the ice, with a high risk for sprained joints or bone fractures. This might have particular comic potential if Randall were skating as part of a pair, awkwardly attempting to lift and spin a partner, or perhaps doing nothing but being lifted and dragged around by them.
|-
| {{w|Horizontal bar}} - A horizontal bar is used to perform gymnastics.|| They might fail to perform any flips or lose their grip on the bar, falling to the safety mats below. In all likelihood, having been lifted to the bar, they would simply hang helplessly beneath it, managing minimal swings backwards and forwards.
|-
| {{w|Equestrian sports}} - Various activities involving the use of horses.|| They might struggle to control the horse or fall/get thrown off.
----
''Randall is shown completely unable to control his horse. He is in the process of falling off and is flailing his arms.
|-
| {{w|Freestyle BMX}} - Contestants ride BMX bikes and perform various tricks, and are then judged by trick quality.|| They might crash or fail to perform tricks.
|-
| {{w|Pommel horse}} - Using a gymnastic device somewhat similar to a horse, gymnasts perform various tricks.|| They might awkwardly flop around, fall off, or lose their balance & risk crushing {{tvtropes|GroinAttack|a particularly squashy part}} of their anatomy, which could, depending on one's sense of humor, the context, & the exact aesthetics of the incident, elicit laughter.
----
''Depicted, Randall is awkwardly perched atop a pommel horse with the rather basic {{w|The_Lexicon_of_Comicana|agitrons}} surrounding him suggesting that he is wiggling some body parts but otherwise not moving much at all. However, he seems to be unaware of this, excitedly demanding that people look at what he presumably thinks is an impressive feat of athleticism.
|}

The title text may be a reference to ski jumper {{w|Vinko Bogataj}}, whose spectacular crash at a (non-Olympic) {{w|Ski_flying|ski flying}} event in 1970 in Oberstdorf, (then) West Germany became emblematic of the expression "the agony of defeat" in the opening narration of the popular US television program "{{w|Wide World of Sports (American TV program)|Wide World of Sports}}". Alternatively the reference may be to {{w|Eddie the Eagle}}, whose poor performance in the {{w|Ski_jumping|ski jump}} at the {{w|1988 Winter Olympics}} led to the introduction of a rule requiring entrants to be ranked internationally in the top 50 and top 30%.

::: Right. That's an odd definition of a cop. You could almost call a fireman a cop (or a cop a fireman), or a donut-store owner.
::: And opinions about the efficacy of the Death Penalty varies (it stops reoffending, as well as any possible full exoneration in the event of a miscarriage of justice; the jury (figuratively and otherwise) is out whether it prevents further crimes by other people, especially those who are already subject to the pressures of 'street justice' with nonjudicial killing a constant threat anyway). Rehabilitation of ''receptive and truly repentent'' criminals is also surely better than letting everyone rot, regardless; or, if/when released, giving them no hope but to be more prolific criminals; and perhaps even relying upon being housed and fed by the penal system again as the only option, so caused more upset to force the courts' hands.
::: It's not really a mixed record, but a mixable interpretation. And "hang 'em all" people will have different perspectives from the "always be forgiving of mistakes" crowd, with the ideal 'truth' likely being somewhere between, and reality always going to err in both directions. So you can disagree about specific judgements and decisions, but be careful of either lauding or lambasting a wider policy shift. Hard cases make bad laws, and bad laws make individual cases hard to deal with.
::: Imagine that you're Glynn Simmons, or Sandra Hemme, or one of those eventually exonerated only ''after'' their exocutions (not necessarily all nice people, but doubts or actual disprooving facts about their parts in any particular Capital crime, or the social goalposts shifted away from discriminatory and heavy-handed policies, is a not an unusual event).
::: All I'm saying is that there's going to be nuance. And every person will have "mixed" approval ratings, even per a given individual's own personal assessment if they know enough to get at least a 2D viewpoint, and ideally at least 3D. And I don't know how anyone without an extreme view on the world would equate a general policy of enhanced rehabilitation with corruptness (when corruption can equally involve framing and improperly prosecuting innocent people, whilst letting the truly irredeemable go free).

:As to your categories: Randall would probably fit in the intersection of the 2nd, 3rd and 4th supercategories (can't rule out he has fit the first, as I don't know what else he's done apart from his NASA stuff and I'm not sure what the definition of "public office" would extend to, anyway (even "elected official" could cover being voted into some position of note in his university's Physics/D&D/Film-Appreciation/Morris-Dancing Society, if he indeed participated in any of that kind of thing at the time).
:And I reckon that almost all the usual politicians you could name could fit into ''at least'' those same three, plus the first if they've actually done any legwork to rise up the ranks to actually get to touch President-worthy status.
:Anyone who doesn't occupy the last two is probably bad at the "would be a good President" of the comic, though given the arguments about how to best interpret the Constitution (even within actual SCOTUS rulings on such issues) then you're likely to get subjective arguments from Candidate A's supporters that Candidate B won't do that as well as from Candidate B's supporters that Candidate A won't do that (to their respective preference). Naming no names, but fairly obvious cases should come to mind. It's possibly that (for a given state of opinion) you could even put any given into your #3 but not in the #4, or vice-versa (but "would be a good President" then depends upon which of these interpretatins you value and which of them you're willing to let slide), rather than the more obvious "both or neiher" dichotomy.

::: They aren't, or at least not metaphors to the tongue. Just done an edit, before having read this, to remove the visibility of "silver tongue" (a tongue that is metaphorically as silver... or maybe even quicksilver) and a "bitten tongue" (the tongue as if restrained by biting). Though there are other forms, the metaphor to biological function must be of the general "it is the tongue of the <something else>" type, maybe such as a tongue of lava or the tongue of an oil-can (one being an extending appendage, the other additionally being a contact depositor of liquid - though not always consistent in application).
::: Something can more easily be understood as the metaphorical heart/nerves/spine/etc of something, and we also have a good understanding of what the originals do. A sewage treatment plant can be considered the kidneys of a town (arguably more understood than a liver of one, for example, so I'd have personally switched the two), but it gets more complex with some of them. In the case of the appendix, we pretty much ''only'' know (in lay-use) that it's a spare fleshy bit that might or might not have any use, so the metaphorical 'equivalent biological function' of a "town's 'appendix'" is probably more understood than a body's ''actual'' appendix, for most peoplez the opposite of the situation with metaphorical/actual tongues.

::A litre of gasoline provides 31.5MJ of energy, and in the US a pump transfers 38 litres (10 USgal) per minute, or 0.633 litres per second. That's an energy throughput of 31.5MJ/l x 0.633 l/s = 19.95MW. And US gasoline pumps are, by law, slow. In the civilised world, petrol pumps can deliver 30% more (50l/minute). Hi-flow diesel pumps used to fill trucks and buses are much faster - between 80 and 120 litres per minute. 120 litres per minute of diesel fuel is an energy transfer rate of about 76MW. By comparison, the fastest 3-phase AC chargers for the Tesla model 3 charge at 11kW; Pumping gas is about 2,000 times faster at getting energy into a car than this. The fastest single phase chargers are 7.4kW; While a standard wall socket charger can manage a paltry 2.3kW, (around a ten-thousandth of the energy transfer rate of a gas pump). The "super" DC charging stations achieve an "impressive" 250kW, making pumping gas at a regular gas station about eighty times faster than using one of these.

: Except of course that this isn't quite as simple as this. A Honda Civic (one the most popular US petrol cars) will go about 400 miles on a full tank, about the same as a Dodge Ram. Also about the same as a Tesla Model S. There's a pretty good reason this isn't a coincidence - people don't want more much more range, and a bigger tank is more weight. A Chevy Silverado full tank will go about 500miles. If you really want range, you need to look at a hybrid car. As the comic points out, the torque on a standard otto cycle engine is poor, but that cycle is deliberately designed to give more torque. Hybrids use an Atkinson cycle which is far more energy efficient, but could not provide enough torque - so you use the electric to do that. A Prius has a range in excess of 630 miles, more than any popular petrol car. So if you want range, you still want an electric engine, just store the energy in hydrocarbons. For similar reasons, diesel trains use the diesel to run generators which then power the electric motors on the wheels, and have done for decades. {{unsigned ip|172.70.162.186|20:47, 19 June 2024}}

The existing dams are aging, their impoundment volumes are dwindling due to sedimentation, and the water for those impoundments is increasingly bespoke and is, in at least some cases, declining in volume due to climate perturbations. The population, and its energy use, is increasing. As of 2022, [https://www.eia.gov/state/?sid=WA#tabs-1 I read], WA was a net exporter of electricity. I would not be taking that status for granted. A few years ago, a study was published, finding that, in states where the electricity grid was dependent on fossil-fuel-fired plants, electric cars had a greater carbon footprint than gasoline/petrol cars - and this was before the major gains in gasoline fuel efficiency contributed by advances in computer tech (2007 Honda Civic hybrid gets the same city mileage, ca. 35 mpg, as a 2021 Honda Civic petrol engine, in my hands). I do not know what current assessments say about this. [[Special:Contributions/172.71.150.129|172.71.150.129]] 04:23, 20 June 2024 (UTC)

:I'd say an electric motor powered by a hydrocarbon grid still usually makes better use of gas than a typical gas engine. Gas engines that don't always run at full throttle (as in, a gas engine in an appliance) have dramatically worse efficiency than electric motors that don't always run at full throttle. It depends ''very'' heavily on use case, though; always take measurements and run the numbers before coming to a specific conclusion. Science would be nothing without empirical data.

: The tagline for the xkcd comic does include the word "sarcasm", which should warn against over-serious or over-literal interpretations. Not infrequently, I find, xkcd ventures into the realm of the sarcastic, the opinionated, even the polemic (cf. the Hilary Clinton campaign ads), and this one states a clear opinion in favor of electric cars ... with which one is free to debate (as here, exhaustively), or disagree. All of which brings the cartoonist to the attention of the world, and thereby supports him in his chosen line of work, which, in the current state of cartooning as a profession, is no small accomplishment. As for the opinion, consider the following question: "I have a four-mile commute to work. Which is the most eco-friendly option? The electric car? The hybrid? The gas/petrol car?" Answer: the foot car. Walking the four miles is the only minimum-carbon solution under all circumstances ... except perhaps ones that allow the questioner to keep deir job.

I actually experienced the "cons" of a less limited degree of power and not being noisy at all, today. Someone in an electric vehicle (could have been a Tesla) pulled out of a sideroad, accelerating at what seemed like a reckless rate (it was advantageous to do so, but a petrol-powered vehicle that might have taken a bit longer to switch up the gears would still have been up to speed soon enough to not get into contention with any other vehicles). And with barely more than a whine, and perhaps a bit of road-noise that might have included at one point a bit of grit-splattering. I was watching this, and knew they were pulling out of the junction (and knew for certain, moreover, that there was no traffic coming up or down the road, nor anybody crossing the road anywhere in my rather long sight). Had there been someone ''actually'' about to cross the road (within the next 50 yards or so), however, it would have been entirely possible that they would have been caught be surprise by this near-silent and suddenly fast-moving vehicle. If it was a Tesla, then maybe its inbuilt forward 'radar'/whatever would have helped bring the vehicle to a stop, or at least slow it down/stop if from speeding up enough, before any actual accident might have happened... but this is theoretical, as it just happened not to happen anything like this on this occasion... But it could have. And the paradigm for crossing the road that I learnt several decades ago of "Stop, Look, Listen, Think" has probably now started to lose out on the "Listen" bit, and possibly degraded even the "Look" and "Think" until we start to retrain ourselves to anticipate vehicles whipping around random corners that are far more silent-and-deadly then what we've all become used to. Ok, so this is not necessarily the total fault of the electric vehicles (or even the drivers, but they must have ''some'' hand in the matter), but in changing the dynamics and situational awarenesses of road traffic so much it ''might'' be considered a relatable problem.

: I drove an electric motorcycle for a while, which put me quite exposed and aware of safety and my driving environment. The concerns about EVs being too quiet don't come across as grounded in reality. Modern ICE vehicles typically have minimal engine noise already. There are really two cases: out on the road, where half the people (exaggerating) have their earbuds in, and any engine noise is swamped by tire noise anyway. No difference between ICE and electric here. Then in a parking lot, where tire noise is not significant, and maybe pedestrians could get extra auditory cues about the vehicles around them from ICE engine noise. In that context, I personally would flip open my visor and make eye contact with pedestrians. It would be nice if drivers of full-sized cars and trucks, no matter their power source, would do more of that. Driving while inattentive is unambiguously bad. [[Special:Contributions/172.69.23.204|172.69.23.204]] 02:40, 20 June 2024 (UTC)
: Rolling noise becomes more than enough for safe audibility by about 30 km/h (below which speed collisions are relatively less dangerous anyways, though most urban streets really should have a speed limit of 20 km/h for numerous reasons including safety), and actually dominates engine noise by about 55 km/h. ICEs are loud enough to have like a dozen deleterious health effects even while idling, though the noise of a bicycle, if sufficiently constant, is enough to reach the WHO threshold. In short, electric cars only need to make additional noise below about 30 km/h for safety, and even then only 55dBA, quieter than typical speech, and even then only if there's already a lot of noise polution to drown them out.

::: Which is best accomplished using narrower streets, bollards, and other traffic easing mechanisms that make people want to slow down and pay attention rather than putting up a lower speed limit sign and just expecting people to obey it. That goes double in the US where most speed limits are assigned by looking at the speeds people are actually driving in good conditions and setting it where 10% of people woulld be speeding (and then rounded to the nearest 5 mph), meaning the sign is literally irrelevant to almost everyone. Oh, also, we desperately need to stop combining streets, which are destinations, with roads, which are thoroughfares, into "stroads" that fail at being both; that's an actual majority of your traffic easing taken care of basically in one step.

We're talking about vehicles, here, not just motors. Also, they emit way less particulate, because of regenerative braking, no fuel burning, absence of particulate-generating parts such as clutches. Modern researhc on particulates, as cited by EEA, is almost unanimous in describing lower particulate emissions, even though the rate of diminution varies according to the scenario.

I'd like to remind everyone here that we want to explain _the comic_ and NOT the pros and cons of EV vs ICE. I'll admit the explaining the points White Hat is making might be in order, anything below that is not necessary for explaining _the comic_. Also, the comic is, as others already pointed out, about engines and NOT about vehicles in general or cars in particular.

:Given the "oh, this isn't electric vs gas ''cookers''" comment, it's probably good to explain that it's gasoline ''fuel'', not natural gas (ethane, mostly)/propane/whatever. I don't know how Leftpondians swerve the confusion between the productand the general state of matter (there'll be times when context ''doesn't'' make it abundantly clear, I imagine), and for the sake of the English speaking world who might not yet have have an internal autotranslate between Amercanized terms and Anglicised ones, it seems like someone thought it was useful. As for the etymology, I always understood it as being originally '''gas'''-''condensate'' (i.e. heavier molecules, falling out of suspension) of cyclic organic compounds ('''-ole'''s, though not necessarily as in strictly "azole"-like) with a fuzzy final suffix ('''{{wiktionary|-ine}}''' ) that might be either a commercial, nominatve ''or'' chemical-name rooted tack-on. Given that gasoline isn't gaseous (or really shouldn't be, to any great degree, during most relevent handling/storing!) I think naming it after its cumes (not exactly obvious, not compared with things like bromine) sounds like a stretch.

==Explanation==
{{incomplete|Created by a GOLGI ENDOPLASMIC RETICULUM. Do NOT delete this tag too soon.}}

This comic shows a {{w|Cell (biology)|biological cell}} diagram with a mix of real and fictional {{w|organelle}}s, giving both accurate {{w|Cell biology|cell biology}} terms and humorous ones. Actual cell components include the nucleus, mitochondria, and Golgi apparatus, while unrelated concepts come from geology, engineering, anitvirus software, and even Star Wars. Labels like "evil endoplasmic reticulum" and "sticky endoplasmic reticulum" are variations of real cellular organelles. Other labels like "pith," "mantle," and "Vitreous humor," are borrowed from other types of circular cross-sectional diagrams (e.g., of fruit, planets, and eyeballs).

The title text is a fictional backstory to the {{w|Golgi apparatus}}, an essential cell organelle involved in processing and packaging proteins. It suggests that {{w|Camillo Golgi}}, the scientist who discovered the Golgi apparatus, was originally an independent organism that 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 is drawn in the comic as a cute little alien.

| Actual cell organelles, found in plant cells and those of several different lineages of non-plant microorganisms and seaweeds. The phrase "if you're lucky" alludes to the good fortune that an organism, be it plant, animal, or microbe, gains by being able to photosynthesize, getting energy from sunlight, rather than have to run around all the time chasing energy. This benefit makes chloroplasts {{w|Kleptoplasty|worth stealing}}. Experiments have been conducted to transplant components of chloroplasts into mammal cells to slow disease.

The idea that a complex tissue can be wrapped around a single cell, as if it were a cell wall, or outer {{w|cell membrane}}, or {{w|extracellular matrix}}, is patently, and humorously, absurd.

2940: Modes of Transportation

2024-06-03T09:50:51Z

}}

==Explanation==
{{incomplete|Created by a Transportationally convenient but insidiously dangerous robotic car - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Randall's chart compares different modes of transportation by how convenient and dangerous they are. At the top-left (high in convenience and low in danger) are airliners and trains, as these are both fast-moving but heavy vehicles on which many millions of dollars have been spent to make them safer. In the top-right, motorcycles are at the same convenience level, but are rated much more dangerous, since they are easy to lose control of at high speeds, and careless drivers (of cars) can easily hit a motorcycle and cause extreme harm. Things like unicycles (bottom-left) are considered much lower on the convenience scale, being not very fast or easy ways to travel, but relatively safe, while towards the centre, skis are apparently moderately convenient and moderately dangerous, since they are relatively easy to fall on if going fast downhill. Way out on their own in the bottom-right, hot air balloons appear to be unique in being rated least on convenience and highest on danger.

Because a hot air balloon is rated so poorly, if an optimization algorithm considers it the optimal mode of transportation, it must be the result of a sign error (e.g. having a minus sign where a plus sign is supposed to be, or vice versa), making the algorithm optimize for the opposite result by mistake. Presumably, modes of transportation similar to hot air balloons (like zeppelins and blimps) are left off the chart to increase the gap for comedic effect.

In order to compare the relative danger from each mode of transport, one can look at statistics of fatalities and injuries sustained during each activity. Traditionally this can be reported in fatalities/{{w|Killed_or_Seriously_Injured|KSI}} per mile driven or passenger mile (or other unit of distance) to account for the fact that some modes are used much more than others, or sometimes also per capita, in order to make historical or international comparisons. However, this is somewhat flawed, since it is really measuring the danger ''to'' users of that mode of transport, both from their own conveyance, and from other sources such as other road users. Since hot air balloon incidents are rare and/or ballooning is not a very common mode of transport, it is difficult to obtain authoritative data for hot air balloons.

The title text makes a joke that if an angry hot air balloon enthusiast disagrees with the ranking, they will have a difficult time getting to Randall's house with their preferred mode of transportation, because they are limited to travelling in the direction of the wind. In reality, hot air balloons have some freedom to choose their direction of travel, since by controlling their altitude they can access different wind directions at different heights. Randall should, therefore, be concerned about hot air balloonists who live within a wedge spanned by the various wind directions accessible on a given day. In principle, if the weather conditions are favorable, this could cover every direction from Randall's house. The phrase "hot air balloon people" is reminiscent of "autogyro people" from the title text of [[1972: Autogyros]].

Curiously, the comic includes most common forms of transport, and a number of less common ones, but omits examples such as buses (a mass transit solution arguably more convenient than trains). It is not clear if this is an error, or a deliberate choice to maintain the comic's layout and presentation.

This is the second comic in a row to feature an algorithm.

2920: Survey Marker

2024-04-17T05:52:47Z

172.69.43.227: /* Explanation */ punc (and primary template)

{{comic

| image = survey_marker_2x.png
| imagesize = 740x272px

}}

==Explanation==
{{incomplete|Created by a GUIDED MISSILE THAT MISSED THE TARGET DUE TO COORDINATE DRIFT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
Cueball and Megan have found a {{w|survey marker}} on the ground. Survey markers such as these are used as reference points for the {{w|North_American_Datum|NAD 83 and NAVD 88}} geodetic reference systems, and the {{w|U.S. National Geodetic Survey}} has a database storing the coordinates of these markers. However, those two systems are being replaced by the {{w|National_Spatial_Reference_System#Datum_of_2022|New Datums of 2022}} (delayed to 2024-2025), which is primarily based on satellite systems and gravimetric models.

When they update the database, in the comic Cueball's altitude changes to compensate (as well as moving his horizontal location) leaving him panicking in mid-air. In reality, updating a database to change the coordinates of a location would not physically move items at the location.{{Citation needed}} Arguably, if they did, no-one would much notice, since everything surrounding them should similarly move simultaneously to its corrected position as well. However, this shifting does not seem to apply to Megan, still standing next to the survey marker, perhaps due to being prepared for the update unlike Cueball.

The title text refers to NAD 83 being around 7 feet off. This is in reference to both {{w|World Geodetic System|WGS84}} and presumably the New Datum.

Absurd outcomes from differing survey standards was also the topic of [[2888: US Survey Foot]].

==Transcript==
:[Zoomed in view of a round marker on the ground, with small specks of dirt around it. There is one line of text going around the central part in the outer rim of the marker, with the first three words written around the top, and the last two words written around the bottom (thus not text that are going all the way around in one single line). Inside this rim there are more text on three lines. In the center there is a small cross in a triangle pointing up in relation to the central text. There are more unreadable text below the last line of text and around the inner part of the rim. And off panel voice, which in the next panel turns out to be Cueball, is written above the mark.]
:U.S. Geological Survey bench mark
:Elevation above sea 447 feet
:Cueball (off-panel): I love finding these survey markers. It's somehow reassuring.

:[Cueball and Megan are shown as they look down on the marker. Cueball has one leg on either side of the marker and Megan stands to the right.]
:Cueball: I like that someone, somewhere, knows where this spot is.
:Cueball: If I stand on it, they know where '''''I''''' am.

:[Cueball and Megan looks up at each other.]
:Megan: But the NAD83 and NAVD88 datums are getting replaced soon. That marker's coordinates could shift by like 5 feet.

:[Megan is looking down at her phone in her hand, standing in the same place in relation to the marker. Cueball is now floating in the air behind her 5 feet above the ground, while flailing with his arms and legs (as shown with three small curved lines at the end of either arm and above and below him.)]
:Megan: Oh look, it just got updated.
:Cueball: '''''Hey! Put me back!'''''
