GOOMHR! - Although for me it was the opposite aim. I've had periods of time when I wouldn't even like (if I noticed, I wasn't like OCD or anything[1]!!!) to make a return journey that meant I even crossed the road at a different point and thus passed under a different telegraph wire between a different set of adjacent poles, on the presumption that if I were to 'retract my path' then it would be irrevocably looped around at least one telegraph poles. (But normal lamp-posts were Ok... the path-'string' could just pass over and around the top and continue to retract. And it could pass above/below anything movable like cars, people, etc.) My ideal would be to be topologically contracted to zero length. Nut I wasn't actually obsessed by it, just... sometimes noticed when I was forced to do something that would cause such 'problems' and might deliberately ensure that any such loop was fully reversed (in strict reverse order to any such transit adding them in) ''if at all possible''. Of course, once it was spoilt by one end of the journey being held by a loop, the rest didn't matter so much. [[Special:Contributions/162.158.34.71|162.158.34.71]] 18:21, 30 September 2022 (UTC)

::If it can conceivably move over your 'thread', then it isn't a 'tangling loop'.

::::Within the period of your concern (e.g. per daily routine), I would presume. That gantry over the road will be (partially, perhaps in stages) dissasembled for maintenance at some point, if not outright taken down, allowing an arbitrarily future-sensitive thread to not be caught up in it any more. Tachyonic thread-behaviour could happily unwrap around the time ''before'' the gantry (or bridges, or arch) were built, and as for the house... Before completion or after the next F5 tornado, the 4D constraints are far less (a line snagged permanently in a 4D 'passage' suggests something a bit more interesting, given a closed door doesn't 'snag' in 3D, only the use of two different doorways, with or without actual doors). But limiting it to a daily assesment bookends the whole 4D construct with a virtual lintel over (and under, in the ''t''-dimension) any potential gap for thread-movement that might be considered a way to be optimising to minimal necessary set of straight-line distances... Well, unless you learn the gantry was only assembled that morning, or that it had sufficient Ship Of Theseus-style repairs during the day, or a truck hit it by the end of the day... then it still acts as a looped-snagger
::::The car is trivial, in comparison, as we ''know'' it drives away in the posited scenario (and within the duration of the scenario). Even if our mental thread-pull does not allow us to tug it under the firmly ground-planted tyres, by reducing to periods of instaniousness as the 'trapped' thread is then rolled over (and even more tightly trapped, without violating the 'through solid matter' issue) you reach a point where it is now rolled ''off'' of (no longer underneath the car at all) so you can consider it untrapped. Unlike any thread that was threaded in through the driver's side door but out again through the passenger-side one, which traps loops completely (except for convertables, of course, or if Black Hat subsequently does a more width-wise [[562: Parking|version of the "cut'n'shut", with or without the "shut" bit]].
::::But that's just my interpretation. Thread-line obsessions probably come in various flavours and twists (can a thread-line knot about itself? And, insofar as the car example, is it basically forced to stay 'loose' but looped under the car as it drives, at least until enough of the car's wheels lose contact with the ground due to excessive speed over a humped bridge or even speedbump?) and I can't speak for all of them, but my reasonable (FCVO 'reasonable') assessment suggests that there are get outs ''and'' constraints that might be more universal than not.

{{cot|When it was all about the OCD}}
This is about a type of OCD where some people feel like they have an imaginary string connecting them to where they come from. As they move around, that string gets entangled and they feel the urge to untangle it. When they enter a car, they feel the need to exit the car from the same door, or else the string will be trapped as forever passing through the car. When they enter a building, they feel they need to exit using the same doorway(s), to avoid entangling the string in the building.

Some cases, like turning around a lamp post are OK because you can imagine removing the loop over the top of the lamp post, such that it is not really entangled.

There may not be an official clinical name for this variety of OCD, but one suggested one is the "imaginary path-string".

Randall treats this OCD like a new measure to add to one's quantified self. The quantified self normally refers to the collection of measurements about your activity, like the number of steps you walk in a day, or monitoring your weight, blood pressure or calories intake. Here, Cueball measures his OCD, i.e. how long this imaginary string has become at the end of the day, after mentally untangling the string as much as possible with valid changes, like moving it around objects, but never through solid matter.

Unlike most people with this OCD, who feel the urge to minimize it, Randall/Cueball takes the opposite stance and actually prefers to maximize the (optimally minimal) length of that imaginary string.

The alt text tells about all the things that become useful adjuncts to this way of thinking and measuring, such as passing (one way) through any tube, tunnel or frame made of solid material that could thus capture the imaginary string and help to keep its ultimate distance as lengthy as possible. All of these situations are dreaded by the people with the more traditional version of OCD.

(It did need a lot of editing, but not sure it is totally inapplicable, given the demonstrated familiarity with the basic concept by Randall's target audience...)

::I also had a preoccupation with this sort of thing, for a while as a child. My magic thread was a remnant of the umbilical cord, with one end permanently anchored in the hospital where I was born. I had little or no knowledge of the fundamental nature of matter and just thought of it as a rubber band that was too small to see or feel. Like in the comic and other comments here, it could magically stretch as much as needed and would un-stretch when possible. I did not consider changing behaviour (e.g. choosing an exit to leave a building) because I had no desire for it to be longer or shorter, and it was clearly far too late to make a significant difference. I did spend quite some time thinking of all the places the thread must have gotten caught (as in the comic) and estimating its total length. (I did not consider airports, or my estimate would have been far longer). [[User:Mrob27|Mrob27]] ([[User talk:Mrob27|talk]]) 06:17, 1 October 2022 (UTC)

;Comics with color, red-line subset
As [[:Category:Comics with color]] doesn't have a currently extant Talk-page to it, mentioning it here (although not sure if this one counts, as much, for my suggestion). Many CwC examples are basically "monochrome with added red" ([[2639: Periodic Table Changes|'corrections' to periodic tables]], e.g.) that are distinct from "having lines of various colours" (like [[657: Movie Narrative Charts|multidata plottings]]), which are in turn distinctive from [[2598: Graphic Designers|floodfilled]] or [[1024: Error Code|brushstroked]] multihue images. A simple(ish) algorithm could autoclassify all images with any non-greyscale pixels in them, but (from a human perspective, which is [[1530: Keyboard Mash|definitely my kind of perspective]]!) I think that we could sub-split CwC candidates into something like "(Monochrome) Comics with added red lines", and the rest. Doubtless some are going to be edge-cases (is this one technically a red-line one? Probably, but it's not really the same as a 'correction/annotation' red-lined comic), but such subcategorisation might still be broadly useful. - Just a wild idea, that you could perhaps safely ignore.

==Explanation==
{{incomplete|Created by an IMAGINARY PATH-STRING STRANGULATION VICTIM. Do NOT delete this tag too soon.}}

[[Cueball]] (presumably a representation of [[Randall]] in this comic) is talking about how he embraces the {{w|quantified self}}, a popular philosophy promoting monitoring yourself with devices and data in the hope to help your well-being. He claims to apply this philosophy to his life, but as is usual for Randall, he does so in his very unique and absurdly humorous way, with help from a smart watch or handheld mobile device.

Typically, fitness apps and wearable devices will track the number of steps that users take and distances walked or run, along with other measurements such as heart rate, blood oxygenation level, blood pressure, and mood.) This is to encourage users to be more physically active. However, Randall has chosen to track a modified version of this metric, in which his path is post-processed by contracting it. Ordinarily, people begin and end their days in bed; in this case, it can get 'caught' where Randall has passed through topological tunnels. (See [[2658: Coffee Cup Holes]] and [[2625: Field Topology]] for details.) In the comic strip, we see that, over the course of his week, Randall has looped around his house twice (which could itself conceal any number of activities, so long as he left through his front door and returned through his back door) and crossed under two highway overpasses, a highway sign, and apparently the St. Louis {{w|Gateway Arch}} before almost returning home.

This comic appeared two days after [https://blog.google/products/search/new-ways-to-make-more-sustainable-choices/ Google's announcement that Maps Directions will be sortable by sustainability.]

===OCD interpretation===

The quantity Randall measures can be recognized as a specific type of OCD where people feel like they have an imaginary string connecting them to where they come from.[https://www.reddit.com/r/OCD/comments/1ve309/invisible_thread_attached_to_my_back_am_i_the/][https://www.reddit.com/r/xkcd/comments/xs50yr/xkcd_2679_quantified_self/iqjcmbv/?context=3]
As they move around, that string gets entangled and they feel the urge to untangle it. When they enter a car, they feel the need to exit the car from the same door, to avoid that the string gets trapped by forever passing through the car. When they enter a building, they feel they need to exit using the same staircases and doorway(s), to avoid entangling the string in the building. Some situations, like turning around a lamp post, are OK because you can imagine removing the loop over the top of the lamp post, such that it is not really entangled.

Randall tries a new approach to deal with this OCD by integrating it in his quantified self. He defines precisely how to measure the length of the imaginary string, reduced to its minimum, and chooses this as a quantity to monitor. Unlike most people with this OCD, who feel the urge to minimize the length, Randall takes the opposite stance trying to maximize the (optimally minimal) length of the string.

This could be thought as a therapy. By defining as a target to achieve a given length every day, he creates a drive to embrace situations that entangle the string. This drive opposes the natural compulsion to avoid them and hopefully cancels it. The joke of the title text is that Randall now becomes overly interested in all the things that are disturbing for people with the OCD. The monitoring has just reversed his obsession.

:We do put those fields there for a reason. Most editors just make a page and leave them incomplete with fields deleted or blank, oftentimes leaving admins with heaps of maintenance work to deal with.

England is part of the mainland of Britain and can't float anywhere on its own without tearing itself away from the rest of the land. It's like suggesting that California can float away from America.

The final number does not agree with the inputs provided in the example. I get 3.00, not 3.51, when I follow the data on the page. Additionally, when I put I use the range or core pressures provided, I get between 2.92 and 3.18.

When we develop software (such as a missile launch briefcase) we sometimes build in safeguards, such as {{w|Two-man rule|needing two people for authorization}}, to prevent mistakes.

Often, such safeguards are a nuisance, thus something else (such as a dual key turner device) is developed to make the safeguards easier to deal with.

When we find out that the thing used to make the safeguards less of a nuisance actually defeats the purpose of the safeguards, rather than simply removing the problem, a new safeguard is added which does the exact same thing as the original, nuisance included.

The ALT-text mentions a one-stop-shop for decentralization which is an oxymoron — a self-contradiction — because a one-stop-shop is by definition centralized.

2675: Pilot Priority List

}}

==Explanation==
{{incomplete|Created by using an ELUCIDATE, EXPLICATE, ANNOTATE, DEMONSTRATE, CITATE AND ILLUSTRATE CHECKLIST. Do NOT delete this tag too soon.}}

The [https://elevate-aviation.com/blog/pilots-priority-checklist "ANC" Pilot Priority Checklist] is a list of three guidelines, sorted by priority, that pilots should follow to prevent them from being distracted. Failing to follow it might make the aircraft crash or suffer other problems. As a {{w|mnemonic}} device, all the activities end in ''-ate''.

# '''Aviate''' means keeping the aircraft in control. If the pilot fails to do this the aircraft might crash, so this should be the highest priority for the pilot.
# '''Navigate''' means knowing where you are and where you're going. Failing to follow this might make the aircraft go into restricted airspace, for example, make the journey take too long, or cause the flight to crash into terrain obscured by clouds.
# '''Communicate''' means talking with air traffic control (ATC) and your company's people through the radio. In the standard list, this is the lowest priority because talking through the radio might distract the pilot from other more important tasks.

By deferring less important activities until the prior need is deemed satisfied, the immediate dangers of flight into terrain ({{w|United Airlines Flight 173|uncontrolled}} and {{w|controlled flight into terrain}}) are reduced — as the pilot's {{w|Loss of control (aeronautics)|current circumstances}} allow — and yet can provide for addressing {{w|Separation (aeronautics)|other hazards}}.

[[Randall]] humorously "extends" this standard list with other ''-ate'' checklist items that pilots could do if they're not too busy aviating, navigating and communicating. These extra tasks range from somewhat hilarious to physically impossible or dangerous; see the [[#Table of extended priority items|table]] below for explanations. These actions {{w|Sterile flight deck rule|should generally not be taken}}, as they could distract the pilot and prevent them from reaching the cabin in case of an emergency, or vaporize everyone inside along with portions of the airframe.

[[File:Airspace classes (United States).png|thumb|Airspace classes in the United States]]

The title text adds another ''-ate'' item to the checklist: Celebrate. It refers to airspace with stricter entry requirements overhead of large airports. In the US, the {{w|Airspace_class_(United_States)|airspace class}} over airports starts with a small circle over the airport and then becomes wider in one or two steps at higher altitudes. When depicted graphically, this looks like an {{w|File:Airspace classes (United States).png|inverted tiered cake}}, as opposed to a [https://3brothersbakery.com/product/wedding-white-chandelier-tier/ regular tiered cake]. Randall suggests that after having congratulated yourself for flying an aircraft, you could then celebrate by serving the passengers cakes in this inverted shape. It would, however, be unsuitable for an aircraft to serve cakes that are smaller at the bottom than at the top because of turbulence.

2671: Rotation

{{comic
| number = 2671
| date = September 12, 2022

}}

==Explanation==
{{incomplete|Created by an IMAGE UPSCALER. Do NOT delete this tag too soon.}}

Another of [[Randall]]'s [[:Category:Tips|Tips]], this tip claims that rotating a phone and taking a screenshot too many times will cause an image to disappear into nothingness and warns the user against doing so. The camera and the display both have limited resolutions, so the detail of the original screenshot at the center of the image will be reduced as it approaches the range of a few pixels, hence the original image will be lost before it reaches the sub-pixel range. This is funny because the default resolution of contemporary camera phones can be too large to meet size requirements for e.g. mobile phone {{w|Multimedia Messaging Service}}, web file uploads, or email attachments, so one or two steps of this awkward procedure are sometimes necessary.

[[Image:World lines and world sheet.svg|thumb|200px|{{w|String theory}} describes the {{w|worldline}}s of point-like particles as {{w|worldsheet}}s of "closed strings," forming a topological foam.]]

For a fuller explanation of the concepts involved, including {{w|Planck units}}, often associated with the topological {{w|quantum foam}} of {{w|string theory}}, please see [https://www.youtube.com/watch?v=pUF5esTscZI this CGP Grey video.] For an explanation of topological string theory, see [[2658: Coffee Cup Holes]]. Please see also [[1683: Digital Data]] for an analogous image processing concept.

The title text refers to producing photographically likely higher resolution images from lower resolutions, an active area of current research.[https://openaccess.thecvf.com/content/ICCV2021/papers/Liang_Hierarchical_Conditional_Flow_A_Unified_Framework_for_Image_Super-Resolution_and_ICCV_2021_paper.pdf] Because reducing the resolution of an image is a lossy process, results obtained through such processes will not be able to perfectly recreate the original. Machine learning can be used to calculate how images of known photographic subjects (or e.g. anime-style art, in the case of {{w|waifu2x}}) behave under certain types of noise or reduction in size, so that images ''of those kinds'' can be upscaled in a way that, if not perfectly recreating the original, at least is a faithful representation, but when the image is scaled all the way down to one pixel, everything except a small amount of data about the image's overall color is lost, making reconstructing the original image impossible. Randall disclaims that, because the AI upscaling is based on ingesting a large corpus of human-made art (with subjects that we find 'interesting' or at least meaningful being predominantly represented), the AI will produce an image that is at least as cool as the original image was, and in fact some image generation AIs actually work on a similar principle -- for example, "reverse diffusion" AIs are trained by teaching them to reconstruct images from noise, at which they can produce entirely new images by being fed ''actual'' noise. He could also be making a pun on {{w|color temperature}}, which the upscaler will be able to match to the original image. The "[https://tvtropes.org/pmwiki/pmwiki.php/Main/EnhanceButton enhance button]" for upscaling images is a common trope in movies and television, especially in crime and science fiction stories.

=== Mathematical corner ===

The scale reduction caused by a rotation can be approximated. If ''a'' is the width of the picture and ''b'' its height, the reduction ''x=a/b'' is the elongation of the picture rectangle. As can be seen on the picture, the rotation leaves two areas on the side of the picture that are roughly squares. Thus, the length ''b'' is equal to two times ''a'' plus the reduced version of ''a'', which is ''x.a'' :
: b = 2a + x.a and since x=a/b, by dividing by ''b'' we obtain 1 = 2x + x^2.
This is a quadratic equation, whose only positive solution is √2-1 ≈ 0.414

The reduction is geometric, so that after nine rotation, the picture will be reduced by a factor of (√2-1)⁹=0,000358937 = 1/2786. Since the original screen resolution is obviously less than 2786 pixels, the original picture will have been reduced to less than a pixel.

25 rotations reduces a lot further and logarithms are needed to compute that. log(√2-1)=−0,382775686, so log(√2-1)²⁵ = 25 x −0,382775686 = −9,569392143. If the original screen is 10cm long, its reduced image will hence be 10^(−9,569392143) times smaller, that is 0.27 10^-10 m, which indeed is smaller than an atom (typically 10^-10 m).

After 101 rotations, the reduction will be 10^(101 x −0,382775686) = 10^−38,660344286 and the 10cm screen will have been reduced to 2.2 10^-40 m.

Well this is embarrassing, this is about a million time '''''smaller''''' than Planck's length, which is only ~ 10^-35 meters. Actually 91 rotations would have been enough to reach Planck's size...

==Explanation==
{{incomplete|Created by a VACCINE DRINKER. Do NOT drink the mRNA Cocktail. Do NOT delete this tag too soon.}}

Approximately two dozenth in [[:Category:Comics featuring cursed items|the "cursed" series]], this comic describes a process to approximate the molecular composition of certain {{w|mRNA}}-based vaccines in drinkable form. It contains the variety and relative concentrations of the simple molecular constituents found within the injectable mixture. i.e. mostly water, some sugar, lipids (and an amino acid "or" biological and genetic material.)

Like much of what we eat or drink, the stomach and intestines will neutralise much of the complexity of either the vaccines or this ersatz replica of them, reducing them to simpler proteins of some slight nutritional value. For the vaccine to work, it has been designed to be injected into the body e.g. {{w|intramuscular}}ly to bypass the hostile environment of the human digestive system. While there are similar vaccines administered as a nasal spray, the fragility of mRNA in the human digestive system has curtailed the search for ingestible analogs. [[Randall]]'s replacement mixture '''might provoke generally unwise physiological reactions.''' While very few people would find such a mixture palatable, it is likely nontoxic,{{Actual citation needed}} and contains water, proteins and calories, all important if elementary nutritional components. Because it doesn't contain a complete spectrum of essential amino acids, vitamins, and minerals,{{Actual citation needed}} you can't live on it alone.

The title text suggests the mixture can be served as a "booster" to a prior dose or serving after an initial treatment. There is much study of vaccine efficacy relative to the timing of subsequent doses. Too little time between makes the new dose not necessarily cause the immune system to react in the way that it should; however most pairs of distinct vaccines work well if delivered on the same day.{{Actual citation needed}} The comic recommends not redosing within two months of the last attempt.

The instruction to serve in {{w|shot glasses}} is a play on words as "shot" can mean {{w|Injection (medicine)|injection}} in medicine. (U.K.: {{wiktionary|jab#Noun|jab}}; Scotland: {{wiktionary|jag#Noun|jag}}).

2665: America Songs

2022-09-14T20:53:50Z

172.70.206.95: /* Table of names matching the rythmic meter of America */ fix link

{{comic

| date = August 29, 2022
| title = America Songs
| image = america_songs.png
| titletext = Juraaaassic Park, Juraaaassic Park, God shed his grace on theeeee
}}

==Explanation==
{{incomplete|Created by a JURASSIC PARK SONGWRITER. Do NOT delete this tag too soon.}}

Many songs, particularly those written by Americans, contain the word "America." Randall has listed 5 such songs: "{{w|America the Beautiful}}", "{{w|God Bless America}}", Neil Diamond's "{{w|America (Neil Diamond song)|America}}", "{{w|America (West Side Story song)|America}}" from the Broadway musical ''{{w|West Side Story}}'', the Guess Who's "{{w|American Woman}}" and Green Day's "{{w|American Idiot (song)|American Idiot}}". These songs usually either praise the United States for its perceived virtues or mock it for its perceived flaws. Regardless of the content of the song, one could likely sing such songs replacing each usage of the word "America" or "American" with another four-syllable word or phrase with emphasis on the second syllable, without disrupting the {{w|cadence}} or meter of the song. Words and phrases like this are said to "{{w|Scansion|scan}}" with the word "America," which means to conform to that metrical pattern.

The comic provides a list of such names, most of which are locations. While some share virtues or flaws with the United States, most would fit into songs about the United States poorly, and only some are prominent enough to justify a song praising or mocking them. So the substitution is humorous for most of the examples. Other examples include Afghanistan, Turkmenistan, Uzbekistan, Tajikistan, Liberia, Nigeria, Bolivia, Siberia, Somalia, Albania, Bulgaria, Colombia, Cambodia, Armenia, Australia, Dominica, Estonia, Mongolia, Romania, Slovenia, Slovakia, South Africa, El Salvador, the Alamo, and the Netherlands.

Note that inhabitants of some real-world locations mentioned in this comic do not pronounce their names in a way that scans with "America". Also note that the adjective form of many of the places listed either does not exist or does not fit the same rhythmic structure as "American". (For instance, while "Antarctican Idiot" scans with "American Idiot", "St. Petersburgian Idiot" does not; meanwhile, "Canada" does not scan with "America", but "Canadian" does scan with "American" and was in fact used as such in Weird Al's parody, "{{w|Canadian Idiot}}".) In these cases, it would be necessary to use the noun form of the name to preserve the song's meter.

The title text provides an example: substituting "{{w|Jurassic Park}}" for "America" in the song "{{w|America the Beautiful}}".

A similar comparison in "scanning" was made in [[1412: Teenage Mutant Ninja Turtles]].

2653: Omnitaur

2022-09-11T11:18:03Z

172.70.206.95: /* Explanation */ acn

{{comic
| number = 2653
| date = August 1, 2022
| title = Omnitaur
| image = omnitaur.png
| titletext = "My parents were both omnitaurs, which is how I got interested in recombination," said the normal human.
}}

==Explanation==

Omnitaur is an {{w|anagram}} of {{w|minotaur}}, a mythical creature that was part man, part bull. "{{wiktionary|Omni}}-" is a prefix that means "all" that is, for instance, known from the word {{w|omnivore}}, meaning 'all eating' as compared to {{w|carnivore}} or {{w|herbivore}} — only eating meat or plant respectively. Given the combination of animals used to create the omnitaur, it could be expected that it was also an omnivore. The "-taur" part often means "bull," but it also appears in "{{w|centaur}}" via Latin from Greek ''kentauros,'' the name for a Thessalonian tribe of expert horsemen, meaning a different mythical creature which has the upper body of a human and the lower body and legs of a horse. So "-taur" could here be used to mean any creature made up of parts of different animals. An "omnitaur" would suggest that it would encompass all real and mythical creatures, or perhaps some random assortment of such. In this instance, it appears to be a hybrid, or {{w|Chimera (genetics)|genetic chimera}}, combined from eleven different creatures: {{w|fish}}, {{w|lion}}, {{w|snake}}, {{w|shark}}, {{w|bull}}, {{w|dragon}} (a mythical and often chimeric creature in its own right), {{w|horse}}, {{w|leopard}}, {{w|Sheep|ram}} (male sheep), {{w|human}} and {{w|bird}}.

Chimerism is not as uncommon at the genetic level, for example humans have about 145 genes (out of around 30,000) originating from bacteria, other single-celled organisms, and viruses.[https://www.science.org/content/article/humans-may-harbor-more-100-genes-other-organisms] {{w|Mitochondria}}, the powerhouses of the cell, were originally chimeric bacteria {{w|symbiosis|symbionts}}. But chimeras of larger organisms are rare, usually involving fraternal twins whose {{w|zygote}}s, {{w|blastocyst}}s, or {{w|embryo}}s combined, as in {{w|conjoined twins}} but resulting in less distinct {{w|phenotype|phenotypical}} expression. Artificial human chimeras with viruses, mice, pigs, and monkeys have been the subject of ethics controversies in recent years.[https://www.theguardian.com/technology/2019/aug/11/the-five-chimeras-human-monkey-hybrid-genetic][https://jme.bmj.com/content/45/7/440.abstract] [https://journals.biologists.com/dev/article/148/12/dev195792/269139/The-road-to-generating-transplantable-organs-from Interspecies blastocyst complementation,] used to create human chimera organs and cell lines in other animals, is usually limited to combining two organisms into one whose offspring are not hybridized if they are even viable, and usually without human {{w|germline}}s or reproductive organs (or human central nervous systems, assuaging a major ethical concern.)

The title text is a comment by a human whose parents were both omnitaurs. It would be funny that such parents would not produce offspring that was still omnitaur. It suggests that this may be the result of {{w|genetic recombination}}, which is the exchange of genetic material between different organisms leading to production of offspring with combinations of traits that differ from those found in either parent. In this case, seemingly, they inherited ''only'' the human elements of each parent, yet sufficient to develop into a whole human with no missing or chimeric elements. Both omnitaur parents likely had human germlines and compatible reproductive organs. Since the example depicted seems to be only 1/11 human, the odds of two parents as mentioned in the title text having fully human offspring would simplistically appear to be (1/11)11, or one chance in 285 billion. In reality, each physical part could not be the result of an equal recombinant genetic contribution, because the eleven animal chromosomes vary widely in number and size. Moreover, chimeras composed of multiple animals do not have chimeric children, because even with multiple sets of reproductive organs, the germlines are not combined.{{Actual citation needed}}

===Chimeras in folklore===
In addition to the minotaur and centaur, many other potential inspirations can be found in mythology, like the {{w|manticore}}, with a body of a lion and human face; a {{w|griffin}}, with a lion's body and a eagle's head; a {{w|mermaid}}, with a lower body of a fish and upper body of a human; a {{w|Hippocampus (mythology)|hippocampus}}, with the upper body of a horse and a lower body of a fish; a {{w|qilin}}, with a body that resembles both a horse and a dragon; or the mythological {{w|chimera (mythology)|chimera}}, for which the genetic chimera is named, which has lion, snake, and goat body parts. Ultimately, there are {{w|List of hybrid creatures in folklore|lots of hybrid creatures in mythology}} with {{w|phenotype}}s combined from multiple animals. Usually, genetic hybridization produces much more smoothly blended phenotypes instead of dividing the body into large distinctly chimeric regions, although {{w|Mosaic (genetics)|mosaicism}} of fur, skin or {{w|Heterochromia iridum|eyes}} can produce notable differences of hue or shade.

In {{w|C. S. Lewis}}' {{w|The Chronicles of Narnia}}, the {{w|Magical_creatures_in_The_Chronicles_of_Narnia#Centaurs|centaurs}} are described as eating two meals — a huge roast meal "to satisfy the man stomach," and a meal of grass, "to satisfy the horse stomach," making it take quite some time for them to eat every morning. Since the omnitaur also has herbivore and omnivore (as well as carnivore) parts, this could further support the supposition that it is an omnivore, and it may similarly need multiple stomachs for these multiple appetites. It is unclear how compatible the various diets of its components would be (not least because 'fish,' 'snake' and 'bird' are quite unspecific, and it's hard to know what a dragon would eat) but it would likely need several meals, taking even longer to eat than the centaur (plus the bird beak may slow the process down quite a bit.) In any case, a chimera of both warm and cold-blooded organisms seems unlikely to be viable,{{cn}} even at the organ level, let alone with combined surface phenotypes.

Dragons in Chinese folklore are often chimeras, [https://www.worldhistory.org/article/1125/the-dragon-in-ancient-china/ described for example] as having, "the head of a camel, the horns of a stag, the eyes of a demon, the ears of a cow, the neck of a snake, the belly of a clam, the scales of a carp, the claws of an eagle and the paws of a tiger." The Chimera monster in {{w|Dungeons and Dragons}} is a "vile combination of goat, lion, and dragon, and features the heads of all three,"[https://www.dndbeyond.com/monsters/16823-chimera] with similar depictions being common across fantasy media. The Aztec god {{w|Quetzalcoatl}} ("the feathered serpent") inspired the {{w|Discworld}} god/demon Quezovercoatl ("the {{w|Boa (clothing accessory)|feathered boa}}") ...being an analogue and mish-mash of various South American cultural and wildlife totems and described more fully as "as half-man, half-chicken, half-jaguar, half-serpent, half-scorpion and half-mad (a total of three homicidal maniacs)" with the small disadvantage of manifesting as only six inches high and being stepped on.

While chimeras occur in fantasy fiction, they also occur in science fiction, for example as {{w|cyborg}}s.{{cn}} The famous ''{{w|The Restaurant at the End of the Universe}}'' sequel to Douglas Adams' ''The Hitchhiker's Guide to the Galaxy'', had a large fat meaty bovine dairy quadruped "with large watery eyes, small horns and what might almost have been an ingratiating smile on its lips." This "Ameglian Major Cow" seemingly had the mind and vocal tract of a human, so it could articulate how much it wanted to be eaten.

:[A creature, the Omnitaur, is shown. It is a four legged animal divided into 11 segments, each segment is from a different animal. An arrow goes to each section from a label, most of the labels are above the animal, but the fourth and seventh segments labels are below the animal. The animal has a fish tail and cat like hind legs. The torso is divided into four segments, the first and last of these with scales, but only the last of these also with sharp scales at the top. The second torso segment is white and smooth, the third also white but with hair both above and below, those above merges with the sharp scales of the fourth torso segment. The front legs are horse like, the lower neck is from an animal with dark spots, the upper neck has rams horns, which goes over in the central part of a human head, with ears and hair (drawn like a real human, not like a xkcd stick figure) and finally the front of the face is a bird with its eyes and a beak shown.

2669: Things You Should Not Do

2022-09-11T10:45:44Z

172.70.206.95: /* Explanation */ upgrade tag

{{comic
| number = 2669
| date = September 7, 2022
| title = Things You Should Not Do
| image = things_you_should_not_do.png
| titletext = Now I'm tempted to start telling people that I secretly don't actually know how to do any physics calculations, and so all the answers in What If are based on me actually trying to do the thing and then reporting what happened, but phrased as if it's hypothetical.
}}

==Explanation==
{{incomplete|Created by a SUNSCREEN BALL. Seem people forget that he learned this from writing the new book, thus no reason to assume they reference old stuff, for instance see the update to the peel the planets crust away, that clearly is a reference to a new what if in the book. Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic references various questions submitted to the what if? blog, and is a promotion for [[Randall]]'s new book, ''What if? 2'' (to be released 6 days from the date of this comic publication). This comic has a list of things not to do, an extension of a previous list, and is purportedly things Randall discovered as he was doing research for his book. A visit to the [https://what-if.xkcd.com/archive/ What If? archive] shows the titles, publishing date, and a thumbnail for each article. Many of the acts described under the "new" section of the list are depicted in these thumbnails (see table below); others are references to examples or hypotheticals explored within the articles. Other entries do not seem to reference currently published ''What If?'' content and may therefore be found in the upcoming book, but this cannot be confirmed as of yet.

The title text says that Randall is tempted to tell people that all the things in the book were things that he actually tried to do, not that he calculated the solutions for their problems. Many of the questions and answers in his new book are impossible to attempt in real life.{{citation needed}}

|A {{w|lava lamp}} is a glass lamp, which contains a wax mixture inside, and heats so that the wax rises and falls. Putting actual lava inside a regular lava lamp would most likely cause the lamp to melt and the glass to shatter, not to mention handling lava is very dangerous.{{citation needed}} However, in [https://what-if.xkcd.com/122/ this entry], Randall says it would be fairly easy to find a material that would be able to handle the heat of the lava and thus this would be rather anticlimactic.

Exceptions for utensils which touch only raw or partially cooked foods, such as grill spatulas and the like, are often allowed and can be negotiated on a case-by-case basis when they would otherwise be prohibited. The rabies virus permeates essentially all nerve tissue before symptoms appear.

Actually doing this, even to county level regulators, could result in a series of events very disadvantageous to you, your farm, and your employees. However, declaring that you're producing Pokémon eggs to your local municipality is probably harmless, and likely to brighten the day of your local regulators.{{cn}}

2670: Interruption

2022-09-10T21:11:19Z

172.70.206.95: /* Explanation */ Bechdel test

{{comic
| number = 2670
| date = September 9, 2022
| title = Interruption
| image = interruption.png
| titletext = It's been extra bad ever since my GPS got stuck on Phoebe Judge mode.
}}

==Explanation==
{{incomplete|Created by a GPS VOICE SYNTHESIZER. Do NOT delete this tag too soon.}}

This comic is about listening to a {{w|podcast}} while driving with GPS navigation using {{w|speech synthesis}} for {{w|turn-by-turn navigation}} driving instructions. Car audio systems typically allow voice navigation instructions to interrupt whatever else is playing so they can be heard clearly. It's usually easy for the driver to recognise such instructions due to the sudden change in characteristics of the voice.

However, if the synthetic voice is similar to the speech that was playing then it may be hard to distinguish between the two, especially if the navigation instructions coincide logically with the interrupted speech. In cases like this, the listener may at first not realise that the navigation instructions have interrupted the audio playing, and think that the instruction is part of the what that they were listening to, especially if they are concentrating intently on driving instead of the audio.

The comic suggests [[Randall]] misinterpreted driving instructions as part of the story being told in a podcast because the voices sound similar. The comic illustrates the instructions as if they were part of the story from the podcast. Due to the mysterious nature of the story and character being described, they conceivably could have said the navigation instruction line as part of the podcast, leading to a humorous ambiguity between the two.

This comic passes the {{w|Bechdel test}}.

The title text suggests this confusion worsened after Randall's navigation instructions voice got stuck emulating {{w|Phoebe Judge}}, known for the {{w|Criminal (podcast)|''Criminal''}} and {{w|This Is Love (podcast)|''This Is Love''}} podcasts, implying he often listens to her.

2668: Artemis Quote

2022-09-05T23:28:10Z

172.70.206.95: /* Explanation */ clarify

{{comic
| number = 2668
| date = September 5, 2022
| title = Artemis Quote
| image = artemis_quote.png
| titletext = Another option: "It is an honor to be the first human to set foot on the moon."
}}

==Explanation==
{{incomplete|created by a COLLABORATIVE EFFORT. Do NOT delete this tag too soon.}}

The {{w|Artemis program}} is a series of planned space missions that will land humans on the Moon and begin to set up infrastructure for a permanent human presence. Humans first landed on the Moon in 1969 as part of the Apollo program. They have not been back since 1972.

When the first human to walk on the Moon, {{w|Neil Armstrong}}, took the first step there, he was intending to say, "That's one small step for '''a''' man, but a giant leap for mankind [emphasis added]." [https://upload.wikimedia.org/wikipedia/commons/4/48/Frase_de_Neil_Armstrong.ogg The audio recording] omits the first instance of the word "a", making the sentence confusing, because ''e.g.,'' conflating "a" man with "mankind" is potentially self-contradictory. This recording was broadcast worldwide at the time and has become a famous historical quote. However, that the {{w|schwa}} grammatical article, "a", optional in certain contexts of most dialects of American English,{{Actual citation needed}} was apparently elided by Armstrong in the excitement, modifying the semantic meaning of the historical phrase, is controversial and therefore funny. Subsequently Armstrong and others have blamed insufficiently tuned {{w|voice activity detection}} hardware circuitry intended to save power in radio voice transmission, but NASA engineers, third-party historians and their hired experts have never been able to corroborate that explanation.

Randall proposes that the first Artemis astronaut should create an even more confusing quote by proposing a sentence that appears to be a reference to what they say. Speaking as if they are alluding to something from the past, it would add contextual confusion to any attempt to directly quote or replay the words from then on. This is very unlikely, and funny merely as a recommendation. If it actually happened, it might be both hilarious and scandalous.

The title text suggests an alternate phrase by which the Artemis astronaut would say being the first (rather than 13th) human on the Moon is a great honor. People hearing this quote in the future could assume that Artemis was the first manned mission to the Moon.

2022-09-05T23:25:42Z

172.70.206.95: Sp.

The first quote is self-referential (and confuses people, when quoted). The second plays unto the myth that the moon landing was staged. It is nice to be able to choose words, which are cited. A great opportunity to confuse people. --[[Special:Contributions/172.68.110.143|172.68.110.143]] 21:09, 5 September 2022 (UTC)

To those of you wondering [https://www.explainxkcd.com/wiki/index.php?title=2668:_Artemis_Quote&diff=294177&oldid=294176 why, "<tt>mankind" ,[emphasis</tt>," currently appears in the wikitext,] I would direct you to [[explain xkcd talk:Editor FAQ#Punctuation inside quotes and parentheses]].

:Waitwhat? ...Quote-Space-Comma-OpenBracket..? Good job it isn't like that now, or I'd be rewriting it. (Probably put the <tt>[emphasis added]</tt> within the quotes, for starters, before worrying about the other punctuation.)

Perhaps the first Artemis astronaut to set foot on the moon will prefer to come with her own idea of what to say. [[Special:Contributions/172.71.142.75|172.71.142.75]] 21:55, 5 September 2022 (UTC)

The quote in the title text is factually true, adding to the confusion it would cause, as it does not actually claim that the Artemis astronaut is the first human to set foot on the Moon, only that it is a great honor to be the first.

I interpreted the second (alt text) option as being intended to cause a similar mis-hearing (or suspected mis-hearing) debate as was the case with the original man/a man quote. The word "human" could possibly be mis-heard as "woman" over a poor-quality audio transmission, leading to a debate about which was intended. (According to the comic, the intended word would in fact be "human", but if the person was female most listeners would likely assume that it is supposed to be "woman" as most people are aware that humans have been on the moon before but probably unsure of whether or not a woman has ever been on the moon.)

Questions: Has a woman ever been to the moon, and is NASA planning to choose a woman for the new mission? It wouldn't surprise me if they were planning to send a woman this time around for PC points. [[Special:Contributions/172.70.91.128|172.70.91.128]] 23:13, 5 September 2022 (UTC)

2666: Universe Price Tiers

2022-09-04T21:58:08Z

172.70.206.95: /* Explanation */ explain 65 mph, especially to non-U.S. readers

{{comic
| number = 2666
| date = August 31, 2022
| title = Universe Price Tiers
| image = universe_price_tiers.png
| titletext = In Universe Pro®™ the laws of physics remain unchanged under time reversal, to maintain backward compatibility.
}}

==Explanation==
{{incomplete|Created by a SOWN WIND - Explained the main point, more details needed. Please change this comment when editing the page . Do NOT delete this tag too soon.}}
Philosophers have posed many questions in trying to understand the nature of the universe. Some of these have become well-known in popular culture; while some are deliberately open-ended, several others are presented as a choice between two or more options, and are assumed to have a single answer, the debate being about which is correct. In this comic, Randall proposes that the answers to these questions are instead not fixed, but vary according to a tiered {{w|subscription business model}}, as seen in many business pricing schemes, particularly in software. In this model, the no-cost tier gets you a universe experience of a lower quality, while at higher tiers better options are available for a cost - for example in the highest tier the processes of aging and death are "Opt-in" rather than "Mandatory". It is not clear from the comic who is supposed to be paying these subscription fees, or to whom they are paid (presumably the developers or maintainers of the universe, or the {{w|Simulation hypothesis|hypothesized simulation thereof}}), or whose experience of the universe is supposed to be affected.

The universe does not have a subscription model,{{Citation needed}} but on the chart some of the categories that refer to observable properties such as the speed limit or existence of the {{w|Uncertainty Principle}} indicate ours is the Universe Standard® subscription. Other specificied settings may not entirely match our user experience. Possibly a high-tier installation has the option to restrict itself to selected lower-tier behaviours, if it is considered more useful.

The title text refers to the concept of {{w|T-symmetry}} in physical laws. Most properties of our universe are asymmetric, meaning that the property changes if time is reversed (e.g. the entropy of the universe decreases as time flows backwards). Randall again makes a reference to software subscription models in a play on words as the Universe Pro®™ sub appears to have laws that maintain "backwards compatibility".

{| class="wikitable"
|-
! !! Universe Lite™ !! Universe Standard® !! Universe Pro®™!!Explanation
|-
! Price
| Free || $14.95/month || $49.95/month || Indicative of a typical Freemium product, the versions released include what is effectively an 'unlimited trial' version, but lacking some potentially desired features, and then extra tiers with increased functionality so that you can "get what you pay for".
|-
! Ads
| Yes || Yes || No || Again typical of a tiered subscription, where ad revenue supports the lower tiers. There are indeed ads in our own universe, but whether they are an intrinsic property of the universe or not is an open question.
|-
! Number of angels that can dance on the head of a pin
| 4 || 64 || 4,096 || "{{w|How many angels can dance on the head of a pin?}}" is a question used to poke fun at medieval angelology and medieval scholasticism in general by claiming discussions in its fields revolve around meaningless questions. It is also used as a metaphor for wasting time debating useless questions, as it is generally accepted that we can have no definitive answer. Here, the question is given concrete answers that are powers of 2 often seen when using binary representation. It may also be a reference to [[485: Depth]].
|-
! Free will or determinism
| Determinism || Free will || Free will || {{w|Determinism}} is the belief that all events and actions are predetermined by the conditions that they arise from, including the part played by our own interactions. This does not imply that such predetermined results are at all predictable, due to the potentially {{w|Butterfly effect|chaotic}} way they may play out, but it implies that personal intentions do not change the future at all and merely form a part of the path of inevitability through the chain of causes and effects.

Such a worldview is countered by the concept of {{w|Free will}}, where some element of consciousness (and thus probably an {{w|Quantum indeterminacy|indeterministic element}} of the universe within which the conscious minds exist) is not absolutely bound by any such rules as set out by the most precise level of physics and/or any {{w|Creator deity|gods}} who were involved.

It is interesting that the paid-for versions of the universe are the only ones to include free will, implying that either such a quality is an inherently desirable feature or else that it is a necessary requirement of some other feature in the paid plan (such as, for instance, the dice-playing mentioned below). As the term "free will" can mean a variety of things, this is partly why it exists as the subject of many debates; here, it may mean "randomness", which the current understanding of quantum physics suggests does exist in this universe.
|-
! Cosmic speed limit
| 65 mph || 300,000 km/s || Unlimited || The Cosmic speed limit refers to the {{w|speed of light}}, which rounds to 300,000 kilometers per second in our particular universe, one of the few definite clues as to which tier we might exist in. Of course the basic joke is conflating that with a vehicular {{w|speed limit}}, typically 65 mph on U.S. highways. Living in a universe with a 65 mph speed limit would render many aspects of experience unrecognizable from our own; assuming the speed of light and thus all relativistic effects were similarly scaled, the act of driving at highway speeds would result in [http://gamelab.mit.edu/games/a-slower-speed-of-light/ human-observable] time dilation and apparent spatial distortion. The {{w|special relativity}} consequences of a low speed of light are explored in one chapter of George Gamow's {{w|Mr Tompkins}}; in Mr Tompkins' dream, the speed of light is approximately 10 mph. The idea of having a speed cap is reminiscent of computer simulations and game engines, which often prevent agents from accelerating beyond a certain point to prevent unintended behavior.
|-
! If a tree falls in a forest and there's no one there to hear...
| No sound || Simple beep || Full sound || {{w|If a tree falls in a forest}} is a popular philosophical question whose answer depends largely on one's philosophical belief system and the interpretation of the question itself. Here it's suggested that there is a definite answer which differs depending on the quality of the universe subscription. On the assumption that "our" universe is on the Standard Plan, this table implies that all trees falling outside of the auditory range of anyone or anything capable of noticing it emit a simplified "beep" sound, rather than the complex crashing one would expect. This concept is similar to the discussion in [[2664: Cloud Swirls]].
|-
! Meaning of Life
| Unknowable || Uncertain || Clearly explained || All we can know is that we (currently) don't know, which makes our universe one almost certainly either with an unknowable or uncertain state of affairs. The closest thing to a meaning of life in this universe that provably exists seems to be natural selection, ie the meaning of life is to spread our genetics, although this is an exceptionally unsatisfying answer. {{Actual citation needed}}
|-
! Sound of one hand clapping
| [None] || [None] || ''Kazzap!'' || A {{w|Koan}} from Buddhism. Koans deliberately have no answer — one hand cannot clap, as the sound of two hands clapping relies upon there being two hands percussing and displacing/resonating air. The "Kazzap" referenced is humorous because it provides an answer to something with no answer, in the form of a nonsense onomatopoeia. To members of our universe, this is absurd. The implication is that those in the Pro version of the universe have access to this seemingly impossible feat.
|-
! Aging and death
| Mandatory || Mandatory || Opt-in || If this is a mere option, we clearly haven't read (or understood) the online manual or perhaps read the tool-tips.
|-
! Does god play dice with the universe?
| Yes, and he cheats || Yes || No || A reference to a phrase famously ascribed to Einstein (in opposition to the concept of quantum uncertainty) that "God does not play dice with the universe." This option and the Determinism/Free Will choice, above, are interestingly linked but not necessarily in a way we can comprehend.
|-
! Bad things...
| Happen to good people only || Happen to good and bad people || Don't happen || Relates to whether there is justice, compassion or fairness in the universe, where good and bad events often seem uncorrelated with whether people morally deserve them. In theological arguments, this debate is intimately connected with theodicy (the problem of how a benevolent god could create a world that contains evil), but like the existence of free will it is hotly debated in non-theological contexts as well. Randall suggests that the situation in a lower-tier universe is even worse, and interestingly that there is no tier where bad things only happen to bad people.
|-
! What happens to those who sow the wind
| Reap the whirlwind || Reap the whirlwind || Lots of crops everywhere || This is a reference to the famous phrase "sow the wind, reap the whirlwind", taken from Hosea 8:7. The phrase means that those who do evil without thought to the consequences will receive punishment. However, in Universe Pro®™, nothing bad happens to anyone, which excludes the possibility of the "whirlwind". This implies that it is possible to ''literally'' sow wind (in the farming sense) in the Pro version, which apparently translates to growing crops in a vastly wider range than normal.

Talk:2667: First Internet Interaction

2022-09-03T21:57:02Z

172.70.206.95: Relate

Is this related to https://www.kerrang.com/green-day-fans-remind-the-internet-not-to-post-wake-me-up-when-september-ends-jokes/ ? {{unsigned ip|172.70.114.87|21:51, 2 September 2022‎}}

((Hey, what a coincidence. You edit-conflict the following ramble (that mentiones the September thing) that I was trying not to make too wordy and mostly failed at...)) 
Not entirely sure what my first Internet thing was (pre-web, might have been telnetting - or even Kermitting - to the software ftp/whatever server at Univeristy of Kent, but that was pretty much not an 'interaction'). And I may have IRCed/Usenetted already, with forgettable results, but I'm fairly sure my very first email to anyone outside of the campus networks (and certainly my first outside of JANET) was to Terry Pratchett. {{cot|...even more boringly nostalgic bit}}
I decided to pointing out something interesting I'd thought of after reading Wyrd Sisters. Which his reply made obvious that he clearly already knew and was definitely riffing off of. (That was me being naive, definitely. It was a very personable knock-back, really. But as 'one of probably many' I never did apologise for my stupidity in any future interactions.)
{{cob}}
Mind you, I'd only just become sort of reassured that I didn't have to pay any kind of postage for email. (Probably.)
 I think I had to wait until after The Eternal September to start getting the comic-like responses. But then I probably lost my patience with various Eternal Septemberites (AOL/WebTV/etc) myself, though never with Greenday details. [[Special:Contributions/172.69.79.173|172.69.79.173]] 22:10, 2 September 2022 (UTC)

is there a related comics section? If so, https://xkcd.com/1053/ is probably related. [[Special:Contributions/172.69.34.8|172.69.34.8]] 00:46, 3 September 2022 (UTC)
:Good one. I know I've seen Green Day mentioned in <s>at least a few other xkcds</s> some other media about Randall. [[Special:Contributions/172.70.214.79|172.70.214.79]] 01:01, 3 September 2022 (UTC)

I think the title text is implying that he does have a serious problem [[Special:Contributions/172.69.33.35|172.69.33.35]] 01:15, 3 September 2022 (UTC)
:The reply was a conditional, so we can't really infer that generality. [[Special:Contributions/172.70.214.59|172.70.214.59]] 01:30, 3 September 2022 (UTC)
: Maybe Cueball's socialization issues. Or possibly that the internet is broadly searchable if you don't know something, so you needn't ask humans. But while I'm outside American culture, I doubt that now or at any time has it been "a serious problem" to not know what or, as it turns out, who is/are "Green Day".
: The name isn't apparently a reference to St Patrick's holiday, but, says Wikipedia, "slang in the San Francisco Bay area" for what I can call taking a herbal holiday. At least, I assume I can, but rules may be subjective. And it's local, so perhaps in New York it does mean St Patrick's Day. Japan celebrates "Greenery Day" for, indirectly, historic reasons. I expect they don't try to say "greenery".
: Anyway, would "AOL Kids" tell you about the San Francisco meaning? It is "A Logic Named Joe" all over again, as has been noticed often. Incidentally, it appears that Green Day were founded as "Sweet Children". Robert Carnegie rja.carnegie@gmail.com [[Special:Contributions/162.158.159.73|162.158.159.73]] 03:12, 3 September 2022 (UTC)
:I know of Green Day (more so after these two comics, obviously) but until now I doubt I'd have mentioned them off the top of my head if I'd have been given an hour to list as many musical acts as I could, except for very isolated instances of prior "oh yeah, someone mentioned this lot earlier". And not sure when they first came to my attention, but probably well post 1993 (and well well post being a 9yo).
:And I couldn't (recent info aside) have actually named any of their songs if asked ''specifically'' about them. Probably heard something they did, some time, but if I've experienced American Idiot then absolutely nothing about it (tune, words or (except since Wednesday) title) seems to have stuck. I have now glanced at their wikipedia article, and... -> Who...my head...osh! ->
:But then I could tell you that Clive Dunn performed "Grandad" and Terry Wogan did the "Floral Dance" and Joe Dolce sang "Whatsa matter you" instead, so probably my serious problem is that I'm just not in their normal target audience. An ocean away and a decade (or probably more) outside their usual fanbase catchment. ;) [[Special:Contributions/172.70.91.128|172.70.91.128]] 03:23, 3 September 2022 (UTC)

This is what I come to explainxkcd for, answers to such questions as “Who or what is or was Green Day (and why should I care)?” and other such things I’ve never come across during my more than six decades of literacy.

My sole knowledge of Green Day is that they released an album called "Dookie", there were two or three songs from it that were on MTV, and I couldn't name any of them today, not even at gunpoint. [[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 09:14, 3 September 2022 (UTC)

To the best of my knowledge, Cueball has always been drawn bald (or at least with no visible hair), yet the 1993 Cueball shows a relatively long and very unkempt growth. Wonder what happened – alopecia? Very early onset of male pattern baldness? Or maybe he just prefers to shave it and rock the Yul Brynner look? [[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 09:24, 3 September 2022 (UTC)
:Not all "child stick-figures" have had hair (obvious girls, like clear women, being the exception for obvious characterisation/distinction reasons) so I presume it's a deliberate contrast. Young Cueball (Who Is Not A 'cueball') clearly had full hair (with maybe a pudding-basin cut/styling?) that was distinctive. Whether, then, Current Cueball has hair so non-descript that there's no depiction that can be done...; whether he is full bald/shaved (because of early male-pattern-baldness/other)...; or whether his hair is just so head-shape-clingy... I don't know.
:Note that Cueball's head (especially in early comics) is not a true oval/ovoid but seems to have a small cusp (about where the crown of his hair would be) that's often usefully depicting his head-attitude but also where the illustrating pen probably started and ended its head-loop. I choose to believe that to be representative of his (short/managed) hair as an abstract of where the hairs might radiate from in a pretty normal hairstyle aithout excessive styling/combovering/etc.
:But there are many possible reasons for any (in)consistent portrayal. Except that it clearly depicts a youth who has changed (perhaps through cynicism of life's many challenges, including online interactions) into the more world-worn current self. [[Special:Contributions/172.70.85.33|172.70.85.33]] 12:40, 3 September 2022 (UTC)

So who else is going to admit they had never heard of Green Day ever before? I sure had not, and I'm an 80s kid living in California. Maybe because I've never been in indie rock bands that much. Does that makes me one of the lucky 10,000 of the day? [[User:Ralfoide|Ralfoide]] ([[User talk:Ralfoide|talk]]) 18:34, 3 September 2022 (UTC)
:It does! [[Special:Contributions/172.70.210.243|172.70.210.243]] 18:51, 3 September 2022 (UTC)

==Explanation==

In this comic, [[Cueball]], as an autobiographical representation of [[Randall]], describes to [[Megan]] the first time he interacted with a group of people unknown to him over the internet; in an {{w|AIM (software)|AOL instant messenger}} forum for children called the "KOOL Tree House chat room" in 1993, when Randall was about nine years old. He read a discussion about {{w|Green Day}}, asked who they are, and was told that not knowing was a serious problem. As Megan says, judging people for lack of pop culture knowledge has remained typical online behavior.

Green Day is an American rock band formed in the East Bay of California in 1987. In 1993, Green Day was still known as an independent punk band and was a year away from releasing their major-label debut album ''{{w|Dookie}}'', their first mainstream success. Anyone, especially a nine year-old, not recognizing the band in 1993 would perfectly normal. After 1993, Green Day would go on to be a widely popular and influential rock band with many acclaimed albums.

This inital online social interaction was apparently a profoundly formative experience for Randall, molding his online behavior ever since, in that it still causes him to consider his correspondents' perspective when communicating. Cueball does not specify how or why the experience affected him, but we know from multiple Xkcd comics that Randall is a Green Day fan (most recently [[2665: America Songs]], referencing the song "{{w|American Idiot (song)|American Idiot}}.") The social dynamics at play are reminiscent of the mathematics of others' perspective when communicating with unknown correspondents described in [[1053: Ten Thousand]].

The title text indicates Randall agrees with the reply to his question, suggesting he believes the band is important culturally.

2667: First Internet Interaction

{{incomplete|Created by AN AMERICAN IDIOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In this comic, [[Cueball]], as an autobiographical representation of [[Randall]], describes to [[Megan]] the first time he interacted with a group of people unknown to him over the internet; in an {{w|AIM (software)|AOL instant messenger}} forum for children called the "KOOL Tree House chat room" in 1993, when Randall was about nine years old. He read a discussion about {{w|Green Day}}, asked who they are, and was told that not knowing was a serious problem. As Megan says, judging people for lack of pop culture knowledge has remained typical online behavior.

Green Day is an American rock band formed in the East Bay of California in 1987. In 1993, Green Day was still known as an independent punk band and was a year away from releasing their major-label debut album ''{{w|Dookie}}'', their first mainstream success. Anyone, especially a nine year-old, not recognizing the band in 1993 would perfectly normal. After 1993, Green Day would go on to be a widely popular and influential rock band with many acclaimed albums.

This inital online social interaction was apparently a profoundly formative experience for Randall, molding his online behavior ever since, in that it still causes him to consider his correspondents' perspective when communicating. Cueball does not specify how or why the experience affected him, but we know from multiple Xkcd comics that Randall is a Green Day fan (most recently [[2665: America Songs]], referencing the song "{{w|American Idiot (song)|American Idiot}}.")

As the title text indicates, he agrees with the reply to his question, suggesting that he believes the band is important culturally.

172.70.206.95: Respond

Many of these rely on "ia"/"ie"/"io" serving as the 3rd and 4th syllables, so every song would be sung like "God Bless <s>Olimpiya</s> Algeriya". Virginia Beach appears to be the only one to escape this.--[[User:Magtei|Magtei]] ([[User talk:Magtei|talk]]) 19:39, 29 August 2022 (UTC)
:As a Washingtonian, I pronounce Olympia without the diphthong (so four syllables; the “a” being distinct). It’s probably a dialect thing, and some pronunciations are more common than others, but as long as one fairly-common pronunciation scans, I think it’s fine. [User:Szeth Pancakes|Szeth Pancakes] ([[User talk:Szeth Pancakes|talk]]) 03:37, 30 August 2022 (UTC)
::Alright, bad example. Skipping it is unheard of in areas further south.

:There are also some locations with three-syllable names, such as Detroit Lakes or Fergus Falls (both located northwest of St. Cloud, Minnesota) which, although not listed by Randall, will also work and not use the noted syllables.

:::I'm not familiar with the term, but I assume it's related to scansion. If I'm right, it's probably just syllables and stress pattern. [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 06:52, 30 August 2022 (UTC)

::::- He said "I do try!
::::- But when I get to the last line I try to fit in as many words as I can."
::::...though – and this is me talking, not the famous limerick – after making sure your poetry rhymes (if you want it to; and/or assonate, consonate, etc) and scans (some words are tricky, as mentioned, according to dialect/accent/etc) you also need to check the meter (does it obviously flow and split in patterns like the iambic one where "da-DUM da-DUM-da DUM-da DUM-da-DUM" might be how it works with word-boundries).
::::You might be wise to avoid words like "vehicle" with theoretically, two to four syllables and all kinds of stress-patterns and vowel-sounds (c.f. stereotypical Deep South, north British, Aussie, etc), at least as an early (establishing) element. Maybe you can set up its far more knowable rhyme/scan/metering partner first and rely upon the reader adopting the intended variation (give or take the relatively opposing strengths of writer/reader accents, etc) after being given the prior clue.
::::I would personally say the scan(sion) is mostly the simple syllable count, and may need some writing tricks ("learned" as in "I learned something" and "learn'ed" as in "a very learned person") to convey well during sight-reading or initial internalised read-through.
::::On that, I personally have some problems reading "-ya" syllables as singular (depending upon what the preceding symbol is, I would consider it a "-ee-ah"/"-ee-uh" (or mid-point) with a cut-down "-ee-"), while I have no problem with the "-lm" dipthong/whatever (c.f. Northern Irish tends to clearly enunciate as "fill-um" for 'film', whilst I might almost consider it a syllable/beat of its own).

Aussie here: we tend to say (and sing) "Australia" with three syllables. For example, see the [https://www.pmc.gov.au/resource-centre/government/australian-national-anthem-scores Australian national anthem]. Occasionally two syllables: Straya mate!!

Needs a better explanation of "scans" (short for Scansion). Something something ''Syllables'', something something ''stress pattern'', something something ''rhythm''. I'd write it myself, but no one wants a 30 page thesis on the topic. PS to those complaining certain locations usually use a three syllable pronunciation... poetic license frequently stretches (usually middle or penultimate) syllables to cover two beats, even without changing vowel length (although it's more common to do so).

2665: America Songs

2022-08-31T03:09:35Z

172.70.206.95: /* Table of places/things */ Explainxkcd is anti-footnotes, because nobody has bothered to make a multicolumn references template yet

{{comic
| number = 2665
| date = August 29, 2022
| title = America Songs
| image = america_songs.png
| titletext = Juraaaassic Park, Juraaaassic Park, God shed his grace on theeeee
}}

==Explanation==
{{incomplete|Created by a JURASSIC PARK SONGWRITER. Do NOT delete this tag too soon.}}

Many songs, particularly those written by Americans, contain the word "America." These songs usually either praise America for its perceived virtues or mock it for its perceived flaws. Regardless of the content of the song, one could likely sing such songs replacing each usage of the word "America" or "American" with another four-syllable word or phrase with emphasis on the second syllable, without disrupting the {{w|cadence}} or meter of the song. Words and phrases like this are said to "{{w|Scansion|scan}}" with the word "America," which means to conform to that metrical pattern.

The comic provides a list of such names, most of which are locations. While some share virtues or flaws with America, most would fit into songs about America poorly, and only some are prominent enough to justify a song praising or mocking them. So the substitution is humorous for most of the examples.

Note that inhabitants of some real-world locations mentioned in this comic do not pronounce their names in a way that scans with "America". Also note that the adjective form of many of the places listed either does not exist or does not fit the same rhythmic structure as "American". (For instance, while "Antarctican Idiot" scans with "American Idiot," "St. Petersburgian Idiot" does not; meanwhile, "Canada" does not scan with "America", but "Canadian" does scan with "American" and was in fact used as such in Weird Al's parody, ''{{w|Canadian Idiot}}''.) In these cases, it would be necessary to use the noun form of the name to preserve the song's meter.

The title text provides an example: substituting "{{w|Jurassic Park}}" for "America" in the song "{{w|America the Beautiful}}".

A similar comparison in "scanning" was made in [[1412: Teenage Mutant Ninja Turtles]].

Talk:2659: Unreliable Connection

172.70.206.95: Typo

I don’t think this has anything to do with teleconferencing. Am I missing something? [[Special:Contributions/172.70.214.81|172.70.214.81]] 22:46, 15 August 2022 (UTC)
:Yes. The impliction is that people are expecting you to be available for online communications, and you can use the unreliable Internet connection as an excuse to get out of it. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 22:51, 15 August 2022 (UTC)
::I think it's more about communication in general. He doesn't want anybody calling him or sending him emails, so by saying he has an "unreliable" connection people might assume it will be hard to get in touch with him.
:::Back in the day, email was usually configured so that it could easily overcome such unreliability, and it's still doable,[https://discourse.mailinabox.email/t/running-from-home/6459/7] but today email for most people is a web or local client-server app, as opposed to a local mail store in a peer-to-peer app. Even people in urban areas can suffer unreliable internet, when squirrels or backhoes gnaw through data cables, copper theives strike, or 5G mind control base stations are congested. [[Special:Contributions/172.70.210.143|172.70.210.143]] 23:45, 15 August 2022 (UTC)
:::This could equally cover other instant communication methods where your availability is advertised (e.g. Whatsapp). It could also be about alleviating the social pressure the subject feels to continuously check and immediately respond to messages (including emails), because the immediacy is already hindered by the spotty connection (cf the standard "I will have limited access to email" out of office line, which gives the account owner psychological permission to check it infrequently).

According to a PhET simulator (https://phet.colorado.edu/sims/html/plinko-probability/latest/plinko-probability_en.html) for this situation, the ideal standard deviation is 1.732 and ideal mean is 6.

:If we assume 50-50 for each bounce, the probability that internet is off will be about (11 choose 3)/(2^11), or 8%.--[[User:Account|Account]] ([[User talk:Account|talk]]) 23:51, 15 August 2022 (UTC)
::My first thought was, why so complicated? ''If'' each of the twelve switches is equally (and solely) likely to be struck by each ball, it's (100/12)% of the time, or 8⅓%.
::Although the equal-chance is wrong, so you're definitely doing "end up with exactly 7 bounce rights and 3 bounce lefts, but in any combination" or similar are you? I'd have summed it differently, though. And not sure where the choose ''3'' comes in... Just one bounce left off any row-end pin 11 sends to 11 if all others bounce right. Three bounces left hits switch 9, not eight. If I'm counting correctly. Or am I doing telegraph-poles/wires miscounting?
::Too early in the morning for me to untangle. The only thing I'm sure about is your division by 2^11 (how many total paths there are to get down). [[Special:Contributions/172.70.91.78|172.70.91.78]] 05:00, 16 August 2022 (UTC)
:::Me again. I hadn't checked that the transcript (which said it was switch #8) was correct. Have now, and found it to be wrong. Have hence also just corrected the Transcript. So I'm gonna assume your 11-choose-3 is entirely correct after all. ;) [[Special:Contributions/172.70.91.78|172.70.91.78]] 05:08, 16 August 2022 (UTC)
:It's actually 12 switches, not 11, but that doesn't affect the math too much. I originally thought "off" was switch 10, which would have changed the math (to 3%), but that's just the one the current ball hit. The actual "off" switch is switch 9. [[User:N0lqu|-boB]] ([[User talk:N0lqu|talk]])
::It previously said that there were eleven "on" switches and one "off" switch (which is twelve in total, but it didn't add them up explicitly), and the change to say that there are 12 Ons and 1 Off made it wrong. I corrected/rephrased it (see if you agree with however it looks by the time you get around to reading this) to avoid that reading error (one which happened to me with my own first glance at the phrasing used, but I thought that was just me at the time) without adding any new misinterpretation or easy misinterpretationality.
::The maths above is indeed correct enough. The 2^11 relates to the total number of unique paths it can take (assuming a bounce left/right just enough to strike the nearest offset pin below to force a new left/right bounce choice) from the first divider through to any of the 11 final left-right pin-bounces (and onto the 12 switches, at which point we're not bothered with the bouncing - diagram suggests the balls leap outwards and don't hit any other switches).
::"11 choose 3" is a way how to ask, given 11 items (possible bounces), how many unique and unordered combinations of exactly 3 of these must exist (leftward-bounces, the rest being right-bounces) to filter onto the off-connected switch. (This is the same as "11 choose 8", if you decide to ask how many right-bounces are necessary, the rest being left-bounces.) That could be layer 1 (the 1-pin), 2 (the 2-pins) and 3 (...), before going consistently right to the final strike of the switch, or layers 9+10+11 (after being pure-right 1..8), but with many intermediate tracks across the pin-spacs (165 in total, as it happens; and it would be 55 to hit switch 10. Or 2, instead of 3, if you orientate things the other way round).
:: 165/2048 (paths hitting the off-switch (at #9) divided by all paths that might happen) is a tad over 8%. On the assumption that it's fair and unbiased and you don't get more rattling around than a simple (single half-step) left/right distribution.

"An added source of humour is that Randall could likely achieve the same effect by looking through the router's settings - which most modern ones have a feature to turn on and off at scheduled times - or via purchasing a smart power strip." But by using these other methods, the connection would still be reliable. If it goes out at regular or pre-scheduled intervals then you know when it will be available or not, hence reliable. I think the joke here is that the contraption does in fact make the connection unreliable. [[Special:Contributions/172.70.114.77|172.70.114.77]] 14:18, 16 August 2022 (UTC)

:(Edit conflicted by at least the above, but my answer to the same question...) From a user POV, unless they happen to know that at 11:53 each day (and 12:14, 15:02, 15:07, 16:31, etc...) the scheduler disables tracfic for one (or two, or three) minutes, it is still unreliable, if ultimately predictable ''once you know'' the schedule, having seen it go round a few times and taken note. Similarly a timered power-strip could be used (or even several, in serial, the two or three daily interventions by the first also stopping and delaying the subsequent strips' interventions, making their timings uneven, further down the chain) and until you got the pattern it might as well be 'random', not entirely deterministic. (I'm wondering about some OR-gate-like/etc implementation, so power can pass by at least one parallel timer-shut-off to maintain power at the lower levels while ''some'' mid-way timers get depowered and thus 'shuffled' in interesting ways, and the resulting single output is governed by an intricate multi-dependent set of routes, but I bet an electrician would be wary about wiring that up...)
:You could hack (or patch) the management firmware to be a bit more (pseudo)random about it, though it would still be pseudorandom LFSR/Xorshift with a (long) repetition cycle.
:Or make it dependant upon an external factor (if the modulo 12 of the cumulative sum of all observed packet-destination IPs is zero, shut off for the five times the prior modulo 12 test value, in seconds..?), but that's ''practically'' the pachinko solution but with software hacking rather than hardware-making/hacking as per the comic.
:More effort is needed to make it ultimately unpredictable, but it can still be considered unreliable if it goes out just when you 'want' it.... [[Special:Contributions/172.70.85.5|172.70.85.5]] 15:02, 16 August 2022 (UTC)

For real though, isn't this kind of a good idea? [[User:Fephisto|Fephisto]] ([[User talk:Fephisto|talk]]) 14:34, 16 August 2022 (UTC)
:Talk to edtech people in the {{w|MOOC}} space and they will tell you asynchronous is worth it, but talk to people who study educational quality factors like time to receive answers to unanticipated questions, and they will have different ideas. [[User:Liv2splain|Liv2splain]] ([[User talk:Liv2splain|talk]]) 14:44, 16 August 2022 (UTC)

Does anyone have an openWRT (or other) implementation of this feature yet?
:You can induce it on stock firmware without reflashing, but you need to know the parameters like how often balls come out of the hopper, and what exactly the on/off switches do. As pseudocode:
::<tt>#!/bin/sh</tt>
::<tt>while true ; do</tt>
:::<tt>sleep </tt>''seconds''
:::<tt>if [ `rand100` -le 8 ] ; then</tt>

::::<tt>wifictrl on</tt>

::<tt>done</tt>
:[[Special:Contributions/172.70.214.81|172.70.214.81]] 00:38, 17 August 2022 (UTC)

There are spaces between the button that the balls can fall into, and this could complicate the stuff a bit. However if the ratio between probability of hitting ON and probability of hitting OFF remain the same (1883:165), the average OFF time will still be the same (165/2048 of the time). The behavior that the network is switching between ON and OFF will probably be changed though. [[User:Lamty101|Lamty101]] ([[User talk:Lamty101|talk]]) 04:44, 17 August 2022 (UTC)

I would have expected the negative reviews to have mentioned all the balls on the floor and perhaps the need to periodically refill the hopper. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 16:18, 17 August 2022 (UTC)
:If it's a Pachinko machine instead of just a Galton board, then refilling the hopper is done automatically by robotics behind the back wall of the device. Someday remind me to tell you about the Japanese recession caused by out-of-work hopper refillers when that innovation was introduced.

I think the joke here is that the contraption does in fact make the connection unreliable. [[Special:Contributions/172.70.114.77|172.70.114.77]] 14:18, 16 August 2022 (UTC)

:(Edit conflicted by at least the above, but my answer to the same question...) From a user POV, unless they happen to know that at 11:53 each day (and 12:14, 15:02, 15:07, 16:31, etc...) the scheduler disables tracfic for one (or two, or three) minutes, it is still unreliable, if ultimately predictable ''once you know'' the schedule, having seen it go round a few times and taken note. Similarly a timered power-strip could be used (or even several, in serial, the two or three daily interventions by the first also stopping and delaying the subsequent strips' interventions, making their timings uneven, further down the chain) and until you got the pattern it might as well be 'random', not entirely deterministic. (I'm wondering about some OR-gate-like/etc implementation, so power can pass by at least one parallel timer-shut-off to maintain power at the lower levels while ''some'' mid-way timers get depowered and thus 'shuffled' in interesting ways, and the resulting single output is governed by an intricate multi-dependent set of routes, but I bet an electrician would be wary about wiring that up...)
:You could hack (or patch) the management firmware to be a bit more (pseudo)random about it, though it would still be pseudorandom LFSR/Xorshift with a (long) repetition cycle.
:Or make it dependant upon an external factor (if the modulo 12 of the cumulative sum of all observed packet-destination IPs is zero, shut off for the five times the prior modulo 12 test value, in seconds..?), but that's ''practically'' the pachinko solution but with software hacking rather than hardware-making/hacking as per the comic.
:More effort is needed to make it ultimately unpredictable, but it can still be considered unreliable if it goes out just when you 'want' it.... [[Special:Contributions/172.70.85.5|172.70.85.5]] 15:02, 16 August 2022 (UTC)

For real though, isn't this kind of a good idea? [[User:Fephisto|Fephisto]] ([[User talk:Fephisto|talk]]) 14:34, 16 August 2022 (UTC)
:Talk to edtech people in the {{w|MOOC}} space and they will tell you asynchronous is worth it, but talk to people who study educational quality factors like time to receive answers to unanticipated questions, and they will have different ideas.

Does anyone have an openWRT (or other) implementation of this feature yet?
:You can induce it on stock firmware without reflashing, but you need to know the parameters like how often balls come out of the hopper, and what exactly the on/off switches do. As pseudocode:
::<tt>#!/bin/sh</tt>
::<tt>while true ; do</tt>
:::<tt>sleep </tt>''seconds''

::<tt>done</tt>
:[[Special:Contributions/172.70.214.81|172.70.214.81]] 00:38, 17 August 2022 (UTC)

There are spaces between the button that the balls can fall into, and this could complicate the stuff a bit. However if the ratio between probability of hitting ON and probability of hitting OFF remain the same (1883:165), the average OFF time will still be the same (165/2048 of the time). The behavior that the network is switching between ON and OFF will probably be changed though. [[User:Lamty101|Lamty101]] ([[User talk:Lamty101|talk]]) 04:44, 17 August 2022 (UTC)

I would have expected the negative reviews to have mentioned all the balls on the floor and perhaps the need to periodically refill the hopper. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 16:18, 17 August 2022 (UTC)
:If it's a Pachinko machine instead of just a Galton board, then refilling the hopper is done automatically by robots behind the back wall of the device. Someday remind me to tell you about the Japanese recession caused by out-of-work hopper refillers when that innovation was introduced.

2651: Air Gap

172.70.206.95: /* Explanation */ paragraph

{{comic
| number = 2651

| titletext = You can still do powerline networking, but the bitrate does drop a little depending on the lightbulb warmup and cooldown delay.
}}

__NOTOC__

==Explanation==

This is another one of [[Randall|Randall's]] [[:Category:Tips|Tips]], this time an Energy Tip. The comic [[#Context for understanding the conflation joke|conflates the concepts]] of computer network security and home electrical power safety to comical effect, resulting in a deeply impractical and ineffective proposed solution. In {{w|computer security}}, {{w|Air_gap_(networking)|air-gapping}} is a measure used to secure sensitive computers or networks of computers by isolating them from the broader internet, since computers are often breached through the internet.

[[Randall]] suggests increasing the security of your home power supply by air-gapping it, using the light from a powered lightbulb to power a solar panel which then supplies power to the home, such that there is no physical wired connection between your house and the public electricity network. This is a large and very inefficient version of an {{w|opto-isolator}}, but would protect equipment behind the solar panel from power surges such as lightning strikes (which in an improperly {{w|Ground (electricity)|grounded}} home could blow out the light bulb, but not so easily risk frying the equipment beyond the photovoltaic cell and its inverter). Due to its inefficiency, this approach would waste substantial amounts of energy. Optical power beaming is being investigated to recharge drones in flight.[https://www.youtube.com/watch?v=9MI2ph9jptM]

The title text mentions that a computer can still be connected to the internet via the power supply by using {{w|powerline networking}}, but that the bandwidth would be reduced by the lightbulb's warmup and cooldown delay, which would reduce the signalling rate the lightbulb could accomplish to no more than hundreds of bits per second, if that, for incandescent bulbs. However, as the solar panel cannot emit signals, the unidirectional link would be useless for traditional networking, because essential requests and acknowledgments would be unable to travel from behind the solar panel to the lightbulb. Early {{w|communication satellite}} systems for data networking used high-bandwidth unidirectional {{w|downlink}}s paired with low bandwidth ground telephone lines for outbound transmission, but such network configurations remain very uncommon.{{cn}}

Randall's solution is of course a joke. But in reality he could have used {{w|isolation transformer}}s, which serve to allow the transfer of power via changing {{w|electromagnetic field}}s without an electrically conductive path. Most transformers, including "wall wart" power adapters, provide this form of isolation and protect devices from noise, voltage transients, most surges, and shock hazard, using fuses and other circuitry. They also limit powerline networking bandwidth by filtering out high frequencies.

The look and subject of this comic is reminiscent of the [[:Category:Cursed Connectors|Cursed Connectors]] series. But without the numbered cursed connector in the comic, this is not one of those connectors.

===Why this would be inefficient and impractical===
* Even energy-efficient LED lightbulbs are only about 35% efficient at turning electricity into light, with the rest emitted as heat.
* The air gap is inefficient at passing light from the bulb to the panel, causing some of the light from the lightbulb to be lost to places other than the solar panel, such as to the eye of the observer. A rough guess might be that in the configuration shown less than 60% of light produced will reach the panel, even assuming a perfect reflector.
* Solar panels are generally around 20% efficient at converting light into electricity, with claims at the world record from a single light source at around 40%.

All these efficiency-reducing factors, and others, multiply together. Therefore, only a small fraction of energy would be transmitted between the two ends of the air gap, making the circuit require much more electricity and be much less cost-efficient. For instance, the generous assumptions above lead to 96% of the power being lost.

The solution as illustrated shows a single apparently-normal lightbulb, which typically draw no more than 250 watts, and usually much less power. Given the above efficiency issues, it would provide less than a tenth as much power.

===How this could have a theoretical benefit===
* There are exotic situations where malware on a computer should not be able to communicate with the outside world. Electricity usage is a simple-to-use side channel which would be made much less practical by such a contraption.

===Context for understanding the conflation joke===
One relatively obscure way this comic is funny involves the relationship of the two concepts being conflated. {{w|Power analysis}} in computer security is a form of {{w|side-channel attack}} where the attacker observes and/or manipulates the power use by a device for some reason — for example, to gain insight into an otherwise protected process, or to exfiltrate information without having to use a monitored network connection. Power analysis in fire safety means measuring the {{w|power factor}}, watts, resistance, inductance, capacitance, volts, and amps of electrical circuits.

2654: Chemtrails

2022-08-24T20:30:00Z

172.70.206.95: /* Explanation */ done

{{comic
| number = 2654
| date = August 3, 2022
| title = Chemtrails
| image = chemtrails.png
| titletext = Ants have reverse chemtrails--regular citizens spraying chemicals everywhere they go to control the government.
}}

==Explanation==

{{w|Entomologist}}s study insects. {{w|Ant}}s are insects that leave chemical trails to and from food sources or other events. These chemical trails can guide other ants in the colony, for instance, to return to food. Biologists call such signaling chemicals {{w|pheromones}}. This comic uses the word chemtrail as a shortening of chemical trail. [[Cueball]] is intentionally conflating ant chemical trails with {{w|chemtrails}}, the subject of a fallacious conspiracy theory that the government controls the population by spraying toxic or mind-/body-transformative chemicals from high altitude aircraft.

That myth may be partly based on the practice of {{w|cloud seeding}}, which uses chemical flares containing silver nitrate to attempt to increase precipitation,[https://www.vox.com/videos/23290459/cloud-seeding-manmade-rain-future-perfect] on studies of chemical mind control among ants,[https://www.sciencedirect.com/science/article/abs/pii/S0022191016301640] or on the effects of the common parasite ''{{w|toxoplasma gondii}}'' on cats' prey. Despite [[1677: Contrails|occasional conflation]], chemtrails are distinct from "contrails," short for "condensation trails," which are cloud-like lines in the sky created by airplane engines. Such linear cloud formations only sometimes arise from temperature and pressure disturbances of the passing engines, rather than any deliberate release, but are highly visible in the right conditions under flightpaths, and may have the appearance of "spraying" action. {{w|Nucleation#Examples of the nucleation of fluids (gases and liquids)|Vapor nucleation}} is central to both cloud seeding and contrails. People sometimes attempt chemical manipulation of unwitting people in small areas (such as scent-based marketing, commercial space scent utilization, or wearing scented products).[https://www.businessnewsdaily.com/3469-smells-shoppers-spend-more.html] There is very little evidence that sophisticated mind control posited by chemtrail conspiracists is possible, even after extensive research.[https://www.google.com/books/edition/Poisoner_in_Chief/U6iDDwAAQBAJ]

[[Ponytail]] is an entomologist, studying chemically mediated cooperative ant navigation. [[Cueball]] knows she will be annoyed when he tells her, "So, I hear you're really into chemtrails?" Indeed, he gets the reaction he hoped for when she objects strongly and rejects this with a loud, "'''No!!'''" The choice of terminology is often a sore spot for those who study a particular field in depth, for example entomological discussions of "slave-making" in socially parasitic species.[https://evolve.community.uaf.edu/2015/04/23/emantcipation-when-captured-ants-rise-against-their-captors/] [[Randall]] writes in the caption that such misuse is how to annoy people like Ponytail.

The title text humorously contrasts individual ants instinctively deciding how the whole colony behaves by using chemicals to indicate routes to food or dangers to motivate the colony to react to their individual experiences, with the human fear of loss of personal independence by being regulated by otherwise disconnected ruling elites, as depicted in the ant/technology interaction speculative fiction-themed [https://www.youtube.com/watch?v=fISvc-yUU1A "Infrared"] music video by the alt-rock band ''Placebo''.

Ants are a recurring theme, as are those who study them. See for instance [[638: The Search]] which specifically deals with ant's pheromone trails or [[1610: Fire Ants]]. Chemtrails were also the subject of [[966: Jet Fuel]], [[1677: Contrails]], and were mentioned in [[1803: Location Reviews]]. This comic has a similar format to [[2036: Edgelord]]: a simple one-panel interaction consisting of a (likely deliberate) misuse of a term in regards to a professional's work, followed immediately by the professional's upset outburst, and Randall's caption spelling out "How to annoy" the professional. Both seem related to Randall's [[:Category:My Hobby|hobbies]], as he seems to think a lot about how to annoy specific groups of people, perhaps in an attempt to minimize annoyances.

2653: Omnitaur

2022-08-24T20:28:37Z

172.70.206.95: /* Explanation */ done

{{comic
| number = 2653
| date = August 1, 2022
| title = Omnitaur
| image = omnitaur.png
| titletext = "My parents were both omnitaurs, which is how I got interested in recombination," said the normal human.
}}

==Explanation==

Omnitaur is an {{w|anagram}} of {{w|minotaur}}, a mythical creature that was part man, part bull. "{{wiktionary|Omni}}-" is a prefix that means "all" that is, for instance, known from the word {{w|omnivore}}, meaning 'all eating' as compared to {{w|carnivore}} or {{w|herbivore}} — only eating meat or plant respectively. Given the combination of animals used to create the omnitaur, it could be expected that it was also an omnivore.

The "-taur" part often means "bull," but it also appears in "{{w|centaur}}" via Latin from Greek ''kentauros,'' the name for a Thessalonian tribe of expert horsemen, meaning a different mythical creature which has the upper body of a human and the lower body and legs of a horse. So "-taur" could here be used to mean any creature made up of parts of different animals.

An "omnitaur" would suggest that it would encompass all real and mythical creatures, or perhaps some random assortment of such. In this instance, it appears to be a hybrid, or {{w|Chimera (genetics)|genetic chimera}}, combined from eleven different creatures: {{w|fish}}, {{w|lion}}, {{w|snake}}, {{w|shark}}, {{w|bull}}, {{w|dragon}} (a mythical and often chimeric creature in its own right), {{w|horse}}, {{w|leopard}}, {{w|Sheep|ram}} (male sheep), {{w|human}} and {{w|bird}}.

Chimerism is not as uncommon at the genetic level, for example humans have about 145 genes (out of around 30,000) originating from bacteria, other single-celled organisms, and viruses.[https://www.science.org/content/article/humans-may-harbor-more-100-genes-other-organisms] {{w|Mitochondria}}, the powerhouses of the cell, were originally chimeric bacteria {{w|symbiosis|symbionts}}. But chimeras of larger organisms are rare, usually involving fraternal twins whose {{w|zygote}}s, {{w|blastocyst}}s, or {{w|embryo}}s combined, as in {{w|conjoined twins}} but resulting in less distinct {{w|phenotype|phenotypical}} expression. Artificial human chimeras with viruses, mice, pigs, and monkeys have been the subject of ethics controversies in recent years.[https://www.theguardian.com/technology/2019/aug/11/the-five-chimeras-human-monkey-hybrid-genetic][https://jme.bmj.com/content/45/7/440.abstract] [https://journals.biologists.com/dev/article/148/12/dev195792/269139/The-road-to-generating-transplantable-organs-from Interspecies blastocyst complementation,] used to create human chimera organs and cell lines in other animals, is usually limited to combining two organisms into one whose offspring are not hybridized if they are even viable, and usually without human {{w|germline}}s or reproductive organs (or human central nervous systems, assuaging a major ethical concern.)

The title text is a comment by a human whose parents were both omnitaurs. It would be funny that such parents would not produce offspring that was still omnitaur. It suggests that this may be the result of {{w|genetic recombination}}, which is the exchange of genetic material between different organisms leading to production of offspring with combinations of traits that differ from those found in either parent. In this case, seemingly, they inherited ''only'' the human elements of each parent, yet sufficient to develop into a whole human with no missing or chimeric elements. Both omnitaur parents likely had human germlines and compatible reproductive organs. Since the example depicted seems to be only 1/11 human, the odds of two parents as mentioned in the title text having fully human offspring would simplistically appear to be (1/11)11, or one chance in 285 billion. In reality, each physical part could not be the result of an equal recombinant genetic contribution, because the eleven animal chromosomes vary widely in number and size. Moreover, chimeras composed of multiple animals do not have chimeric children, because even with multiple sets of reproductive organs, the germlines are not combined.

===Chimeras in folklore===
In addition to the minotaur and centaur, many other potential inspirations can be found in mythology, like the {{w|manticore}}, with a body of a lion and human face; a {{w|griffin}}, with a lion's body and a eagle's head; a {{w|mermaid}}, with a lower body of a fish and upper body of a human; a {{w|Hippocampus (mythology)|hippocampus}}, with the upper body of a horse and a lower body of a fish; a {{w|qilin}}, with a body that resembles both a horse and a dragon; or the mythological {{w|chimera (mythology)|chimera}}, for which the genetic chimera is named, which has lion, snake, and goat body parts. Ultimately, there are {{w|List of hybrid creatures in folklore|lots of hybrid creatures in mythology}} with {{w|phenotype}}s combined from multiple animals. Usually, genetic hybridization produces much more smoothly blended phenotypes instead of dividing the body into large distinctly chimeric regions, although {{w|Mosaic (genetics)|mosaicism}} of fur, skin or {{w|Heterochromia iridum|eyes}} can produce notable differences of hue or shade.

In {{w|C. S. Lewis}}' {{w|The Chronicles of Narnia}}, the {{w|Magical_creatures_in_The_Chronicles_of_Narnia#Centaurs|centaurs}} are described as eating two meals — a huge roast meal "to satisfy the man stomach," and a meal of grass, "to satisfy the horse stomach," making it take quite some time for them to eat every morning. Since the omnitaur also has herbivore and omnivore (as well as carnivore) parts, this could further support the supposition that it is an omnivore, and it may similarly need multiple stomachs for these multiple appetites. It is unclear how compatible the various diets of its components would be (not least because 'fish,' 'snake' and 'bird' are quite unspecific, and it's hard to know what a dragon would eat) but it would likely need several meals, taking even longer to eat than the centaur (plus the bird beak may slow the process down quite a bit.) In any case, a chimera of both warm and cold-blooded organisms seems unlikely to be viable,{{cn}} even at the organ level, let alone with combined surface phenotypes.

Dragons in Chinese folklore are often chimeras, [https://www.worldhistory.org/article/1125/the-dragon-in-ancient-china/ described for example] as having, "the head of a camel, the horns of a stag, the eyes of a demon, the ears of a cow, the neck of a snake, the belly of a clam, the scales of a carp, the claws of an eagle and the paws of a tiger." The Chimera monster in {{w|Dungeons and Dragons}} is a "vile combination of goat, lion, and dragon, and features the heads of all three,"[https://www.dndbeyond.com/monsters/16823-chimera] with similar depictions being common across fantasy media. The Aztec god {{w|Quetzalcoatl}} ("the feathered serpent") inspired the {{w|Discworld}} god/demon Quezovercoatl ("the {{w|Boa (clothing accessory)|feathered boa}}") ...being an analogue and mish-mash of various South American cultural and wildlife totems and described more fully as "as half-man, half-chicken, half-jaguar, half-serpent, half-scorpion and half-mad (a total of three homicidal maniacs)" with the small disadvantage of manifesting as only six inches high and being stepped on.

While chimeras occur in fantasy fiction, they also occur in science fiction, for example as {{w|cyborg}}s.{{cn}} The famous ''{{w|The Restaurant at the End of the Universe}}'' sequel to Douglas Adams' ''The Hitchhiker's Guide to the Galaxy'', had a large fat meaty bovine dairy quadruped "with large watery eyes, small horns and what might almost have been an ingratiating smile on its lips." This "Ameglian Major Cow" seemingly had the mind and vocal tract of a human, so it could articulate how much it wanted to be eaten.

==Transcript==
:[A creature, the Omnitaur, is shown. It is a four legged animal divided into 11 segments, each segment is from a different animal. An arrow goes to each section from a label, most of the labels are above the animal, but the fourth and seventh segments labels are below the animal. The animal has a fish tail and cat like hind legs. The torso is divided into four segments, the first and last of these with scales, but only the last of these also with sharp scales at the top. The second torso segment is white and smooth, the third also white but with hair both above and below, those above merges with the sharp scales of the fourth torso segment. The front legs are horse like, the lower neck is from an animal with dark spots, the upper neck has rams horns, which goes over in the central part of a human head, with ears and hair (drawn like a real human, not like a xkcd stick figure) and finally the front of the face is a bird with its eyes and a beak shown.

__NOTOC__

==Explanation==

This is another one of [[Randall|Randall's]] [[:Category:Tips|Tips]], this time an Energy Tip.

The comic [[#Context for understanding the conflation joke|conflates the concepts]] of computer network security and home electrical power safety to comical effect, resulting in a deeply impractical and ineffective proposed solution. In {{w|computer security}}, {{w|Air_gap_(networking)|air-gapping}} is a measure used to secure sensitive computers or networks of computers by isolating them from the broader internet, since computers are often breached through the internet.

[[Randall]] suggests increasing the security of your home power supply by air-gapping it, using the light from a powered lightbulb to power a solar panel which then supplies power to the home, such that there is no physical wired connection between your house and the public electricity network. This is a large and very inefficient version of an {{w|opto-isolator}}, but would protect equipment behind the solar panel from power surges such as lightning strikes (which in an improperly {{w|Ground (electricity)|grounded}} home could blow out the light bulb, but not so easily risk frying the equipment beyond the photovoltaic cell and its inverter). Due to its inefficiency, this approach would waste substantial amounts of energy. Optical power beaming is being investigated to recharge drones in flight.[https://www.youtube.com/watch?v=9MI2ph9jptM]

The title text mentions that a computer can still be connected to the internet via the power supply by using {{w|powerline networking}}, but that the bandwidth would be reduced by the lightbulb's warmup and cooldown delay, which would reduce the signalling rate the lightbulb could accomplish to no more than hundreds of bits per second, if that, for incandescent bulbs. However, as the solar panel cannot emit signals, the unidirectional link would be useless for traditional networking, because essential requests and acknowledgments would be unable to travel from behind the solar panel to the lightbulb. Early {{w|communication satellite}} systems for data networking used high-bandwidth unidirectional {{w|downlink}}s paired with low bandwidth ground telephone lines for outbound transmission, but such network configurations remain very uncommon.{{cn}}

Randall's solution is of course a joke. But in reality he could have used {{w|isolation transformer}}s, which serve to allow the transfer of power via changing {{w|electromagnetic field}}s without an electrically conductive path. Most transformers, including "wall wart" power adapters, provide this form of isolation and protect devices from noise, voltage transients, most surges, and shock hazard, using fuses and other circuitry. They also limit powerline networking bandwidth by filtering out high frequencies.

The look and subject of this comic is reminiscent of the [[:Category:Cursed Connectors|Cursed Connectors]] series. But without the numbered cursed connector in the comic, this is not one of those connectors.

===Why this would be inefficient and impractical===
* Even energy-efficient LED lightbulbs are only about 35% efficient at turning electricity into light, with the rest emitted as heat.
* The air gap is inefficient at passing light from the bulb to the panel, causing some of the light from the lightbulb to be lost to places other than the solar panel, such as to the eye of the observer. A rough guess might be that in the configuration shown less than 60% of light produced will reach the panel, even assuming a perfect reflector.
* Solar panels are generally around 20% efficient at converting light into electricity, with claims at the world record from a single light source at around 40%.

All these efficiency-reducing factors, and others, multiply together. Therefore, only a small fraction of energy would be transmitted between the two ends of the air gap, making the circuit require much more electricity and be much less cost-efficient. For instance, the generous assumptions above lead to 96% of the power being lost.

The solution as illustrated shows a single apparently-normal lightbulb, which typically draw no more than 250 watts, and usually much less power. Given the above efficiency issues, it would provide less than a tenth as much power.

===How this could have a theoretical benefit===
* There are exotic situations where malware on a computer should not be able to communicate with the outside world. Electricity usage is a simple-to-use side channel which would be made much less practical by such a contraption.

===Context for understanding the conflation joke===
One relatively obscure way this comic is funny involves the relationship of the two concepts being conflated. {{w|Power analysis}} in computer security is a form of {{w|side-channel attack}} where the attacker observes and/or manipulates the power use by a device for some reason — for example, to gain insight into an otherwise protected process, or to exfiltrate information without having to use a monitored network connection. Power analysis in fire safety means measuring the {{w|power factor}}, watts, resistance, inductance, capacitance, volts, and amps of electrical circuits.

2650: Deepfakes

2022-08-24T20:25:52Z

172.70.206.95: /* Explanation */ done

{{comic
| number = 2650
| date = July 25, 2022
| title = Deepfakes
| image = deepfakes.png
| titletext = If so great a deductive mind as Arthur Conan Doyle can be fooled by the Cottingley Deepfakes, what chance do we mortals have? Soon our very reality will be dictated by the whims of Frances (9) and Elsie (16).
}}

==Explanation==

A {{w|deepfake}} is an altered video, designed to deceive, by replacing a person in a video with someone else. [[White Hat]] believes that this technology will make it difficult to trust video evidence from now on. However, [[Cueball]] responds by saying that "fakes" have always existed, in photos (either through {{w|photoshopping|alterations by software such as Adobe Photoshop}}, or deliberately staging faked images, for example {{w|Loch Ness Monster#%22Surgeon's photograph%22 (1934)|of the Loch Ness Monster}}) and even more so by people simply lying. White Hat comes around to Cueball's position and says that even the written word is prone to deception and lying.

Scientific studies of deepfakes have produced surprising results, suggesting that they are more likely to increase uncertainty than persuade,[https://journals.sagepub.com/doi/full/10.1177/2056305120903408] that their increased prevalence could inoculate the public against {{w|disinformation}},[https://dspace.cuni.cz/handle/20.500.11956/150489] and that they are more likely to be shared because of their humorousness than persuasiveness.[http://essay.utwente.nl/91654/] Other studies have found that deepfakes are persuasive, especially among those who are unfamiliar with them.[https://www.liebertpub.com/doi/abs/10.1089/cyber.2020.0174][https://www.osti.gov/biblio/1780812]

The {{w|complaint tablet to Ea-nasir}} is a 3,800 year-old clay tablet containing the oldest known written complaint, in which a customer complains to a merchant, Ea-nasir, about the quality of his copper ingots. Cueball's last statement says that perhaps this complaint could have been a lie to begin with, and there was nothing wrong with Ea-nasir's wares. This supposition is arguably the humor of the comic, apart from the hyperbole of the title text.

The title text references the {{w|Cottingley Fairies}}, a series of five photographs produced in 1917 by two children, Elsie Wright and Frances Griffiths, who were 16 and 9, respectively. The photographs appear to show the children playing with fairies in their garden. The photographs received widespread attention when Sir {{w|Arthur Conan Doyle}}, the author of the {{w|Sherlock Holmes}} stories, used the photos as proof of paranormal phenomena in a 1920 magazine article. Conan Doyle was noteworthy for being a strong proponent of reaching conclusions based on evidence and reason, and also held a deep belief in paranormal and supernatural phenomena. In 1983, Elsie and Frances finally confessed that the photos had been faked, by the simple process of making and posing cardboard cutouts traced from figures in a children's book with wings added. Due to technical advances, young children now can more easily create convincingly realistic fakes,{{Actual citation needed}} but similarly there are many more self-styled 'experts' willing and able to dedicate themselves to 'proving' one or other side of any argument about authenticity.

A similar dilemma was alluded to in the [[1958: Self-Driving Issues]] comic, where technology does not create a new way to lie, but may make certain lies more convincing to some parties, such as self-driving cars in that comic.

2647: Capri Suns

{{comic
| number = 2647
| date = July 18, 2022
| title = Capri Suns
| image = capri_suns.png
| titletext = [As security is dragging me away] "Come on, at least I didn't make the mistake in the other direction!"
}}

==Explanation==

[[Cueball]] has been impersonating a doctor at a hospital. But his attempt to fool the staff (including [[Megan]] and [[:Category:Doctor Ponytail|Doctor Ponytail]]) fails when he mistakes a saline bag (as [https://imgs.xkcd.com/comics/capri_suns_2x.png labeled when zoomed in]) for a Capri Sun juice drink.

{{w|Capri Sun}} is a fruit juice concentrate beverage that comes in soft rectangular mylar bags with a small seal near the top, to be pierced with an included straw so as to sip the drink. {{w|Saline (medicine)|Saline}} bags, used in hospitals and other medical settings, are also soft and rectangular, with an {{w|Intravenous therapy#Medical uses|intravenous}} (I.V.) drip connection about the same size as such straws, and usually contain a 0.9% sodium chloride (table salt) solution in sterile water so they are salty enough to be {{w|Tonicity#Isotonicity|isotonic}} with blood. Capri Sun is mostly sugar water, and only 0.00008% salt,[https://www.aqua-calc.com/calculate/food-volume-to-weight/substance/capri-blank-sun-coma-and-blank-fruit-blank-juice-blank-drink] so it tastes sweet instead.

Almost everyone would be very unlikely to accidentally mistake saline bags for Capri Sun, especially a medical doctor.{{Citation needed}} Cueball begins to realize that his attempt to impersonate a doctor has derailed when the hospital staff notice that he made such an absurdly unlikely and therefore humorous error.

The title text makes it clear that Cueball is being removed from the hospital by security personnel. While they are dragging him out, he tries to point out that drinking saline is better than putting Capri Sun into a patient's I.V. drip, as it would endanger the patient,[https://www.bbc.com/news/world-asia-china-47623816] arguing that this mitigates the severity of his transgression. The guards apprehending him are unlikely to be persuaded, as impersonating hospital staff is a serious offense with dangerous risks and severe consequences. In California, the unlicensed practice of medicine can result in a maximum $10,000 fine, up to three years in prison, or both.[https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=BPC&sectionNum=2052.]

The comic arguably continues [[451: Impostor]] and [[699: Trimester]].

==Transcript==
:[Cueball, wearing a lab coat, is drinking out of a straw inserted into an IV drip bag that is labeled "saline" (on the 2x image; it is rendered unreadable on the standard resolution version, just like the rest of the label's squiggles). Cueball is surrounded by hospital staff. To the left is Megan with a white hat, she is holding a clipboard, with a paper with unreadable text. To his right is Dr. Ponytail holding a rolled up paper under one arm and, to the right of her, a man with a similar hat as Megan. They are all looking at Cueball.]
:Cueball: You know, these Capri Suns are good, but they're ''really'' salty.

2640: The Universe by Scientific Field

2022-08-24T20:24:43Z

172.70.206.95: /* Explanation */ done

{{comic
| number = 2640
| date = July 1, 2022
| title = The Universe by Scientific Field
| image = the_universe_by_scientific_field.png
| titletext = The math and philosophy people also claim everything, but the astronomers argue that the stuff they study really only comprises a small number of paper surfaces.
}}

==Explanation==

{{w|Astronomy}} is the study of outer space and celestial phenomena. This comic makes a joke that most of the "universe" falls under the study of astronomy, which makes sense because it is so vast and large and is not studied directly by other fields of science.

The volume of the {{w|observable universe}} is 3.566×1080 cubic meters. The volume of Earth is 1.08321×1021 cubic meters.

1.08321×1021 m3 ÷ 3.566×1080 m3 × 100% ≈ 3×10-58%, which is scientific notation for the second of the two percentages, the first being its difference from 100%.

Thus, the universe is comprised almost entirely of the objects of astronomical study, when measured by volume.

There are many arguments to be made that this is not the most useful way of measuring the size of scientific fields compared to the universe. If we measure the universe by mass-energy{{cn}} instead, for example, the study of physics becomes non-trivial. Other arguments include:
*Astronomers are only studying the {{w|Observational astronomy|observable phenomena}} (i.e. light, subatomic particles, and gravity) of the rest of the universe, leaving the vast majority of the universe's properties (for instance the geology and biochemistry of an unknown planet in a distant galaxy) entirely unstudied.
*Astronomy is only possible due to understanding of physics, optics, chemistry, mathematics, and geometry, so surely they deserve some credit.
*The interesting parts of the universe are not the empty space.
**They are the matter and energy described by physics and chemistry.
**They are the life experiences of people, which are overwhelmingly terrestrial even for professional astronomers (who often complain about how little time they can allocate to making actual astronomical observations).
*It is disingenuous to claim to be studying more than every other field when astronomy and astrophysics publications amount to only about 0.5% of academic science and engineering output worldwide.[https://ncses.nsf.gov/pubs/nsb20214/table/SPBS-34] Other fields may be studying smaller things, but they are studying them much more thoroughly.
*Emptiness has less information and is less interesting than non-emptiness; therefore geometric volume is only very weakly correlated with useful information.

A counterargument is that astronomy, {{w|cosmology}}, and astrophysics are the only scientific disciplines that study the {{w|Big Bang}} and subsequent {{w|Inflation (cosmology)|inflation}} from which all matter, energy, and space itself arose. The ordinary laws of physics can describe neither of those events.

The title text says that mathematicians and philosophers claim that what they study also represents everything. But (according to the comic) astronomers counter this by saying that they just study things that are written down, and this comprises just tiny amounts of "paper" on the Earth. This claim by mathematicians also appears in [[435: Purity]]. A conceivable counterargument by philosophers could be that any and all science, including astronomy, is nothing more than a branch of {{w|epistemology}}, the philosophical study of knowledge. Another could be that since philosophy includes theology, it is studying something even larger than the universe (although one could argue back that theology is nothing more than writing fiction.)

2642: Meta-Alternating Current

172.70.206.95: /* Explanation */

{{comic

| titletext = It's always bothered me that you can't cancel out an inverter by putting a second inverter after it.
}}

==Explanation==
This is another one of Randall's [[:Category:Cursed Connectors]] comics.

{{w|Direct current}} is a unidirectional flow of electrons from a power source to something being powered, through one or more conductors, before returning to the power source via one or more other conductors, thus completing the circuit. Batteries produce direct current. It is commonly used in electronics applications, including computers. {{w|Alternating current}}, on the other hand, frequently reverses the direction of electron flow, and is commonly used for longer-distance transmission (such as from the power plant to an outlet).

This comic proposes a humorous ''Meta-Alternating Current'', which uses a series of adapters to "alternate" between DC and AC current along the length of a connector. This is absurd in part because typical {{w|power inverter}} efficiency is 90%, and maximum {{w|bridge rectifier}} efficiency is about 99% for 120 V,{{citation needed}} so an {{w|extension cord}} made of in this manner would lose about 10% power per such pair.

The title text bemoans that an inverter, which converts direct current to alternating current, does not work in the other direction, as a layman's interpretation of the word "inverter" might assume. Rather, a separate device, a {{w|rectifier}}, also pictured in the comic, must be used for this second conversion. (However, a similar circuit to an inverter may be used to rectify in a process called {{w|active rectification}}.)

2643: Cosmologist Gift

2022-08-24T20:22:07Z

172.70.206.95: /* Explanation */ done

{{comic
| number = 2643
| date = July 8, 2022
| title = Cosmologist Gift
| image = cosmologist_gift.png
| titletext = These neutrinos were freshly produced by a local source just 8 minutes ago
}}

==Explanation==

This comic shows a box labeled to indicate that it contains 30,000 fresh {{w|neutrino}}s and four zeptograms of {{w|dark matter}}. The box is intended as an inexpensive gift for a {{w|cosmologist}}. The gift giver didn't put those things in the box—both are simply passing through it, so the "gift" consists of exactly what was in the empty space it occupies. While the caption suggests this would be a good gift for a cosmologist, what they or anyone else would do with such a box is uncertain.

There are about a billion neutrinos per cubic meter throughout space, produced during the {{w|Big Bang}}.[https://physics.mit.edu/news/journal/physicsatmit_14_conrad/] However, the flux of "freshly produced" {{w|solar neutrino}}s at Earth is around 6.5×1010/cm2/s, yielding about 2.1 million per cubic meter, and implying the box is around 12 liters, three quarters as big as a typical {{w|breadbox}}.

Four zeptograms is a minuscule mass, equal to four sextillionths of a gram, the mass of about 200 carbon-12 atoms or around 20 to 23 {{w|amino acid}}s. There is an estimated 0.011 to 0.016 {{w|solar mass}}es of dark matter per cubic {{w|parsec}} local to the solar system,[https://iopscience.iop.org/article/10.1088/1361-6633/ac24e7/meta] or about 900 zeptograms per cubic meter, suggesting the box is closer to 4 liters. This discrepancy [[2035: Dark Matter Candidates|could imply Randall agrees]] with cosmologists who believe dark matter is partially composed of {{w|primordial black hole}}s,[https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.121301][https://www.sciencedirect.com/science/article/abs/pii/S2212686418301250?via%3Dihub][https://news.yale.edu/2021/12/16/black-holes-and-dark-matter-are-they-one-and-same][https://iopscience.iop.org/article/10.3847/2041-8205/823/2/L25][https://iopscience.iop.org/article/10.1088/1475-7516/2010/04/023] instead of being composed entirely of ubiquitous subatomic particles. This comic coincided with the [https://www.nasa.gov/image-feature/goddard/2022/nasa-s-webb-delivers-deepest-infrared-image-of-universe-yet first James Webb Space Telescope science image release to the public] containing {{w|gravitational lens|gravitationally lensed}} very distant {{w|quasar}}s and {{w|population III star}}s, the spectra of which can be used to test [https://twitter.com/SheerPriya/status/1546576050976870400/photo/1 certain hypotheses associated with dark matter being black holes.] A billion neutrinos have a mass of only about 2×10-12 zeptograms, at about 0.1 {{w|electron volt}}s each.

The "local source" mentioned in the title text is a joke about the commercial value of fresh, locally produced items, but the comic means that the neutrinos come from the Sun. It takes solar neutrinos slightly more than 8 minutes to reach Earth once they're emitted, roughly the same time as photons take to make the trip. (While [https://en.wikipedia.org/wiki/Radiative_zone energy takes approximately 170,000 years to reach the Sun's surface from its core,] where the fusion reactions occur, the neutrinos are not slowed down inside the Sun and travel at about 99.9999999999% of the speed of light.

==Explanation==

[https://www.goodreads.com/book/show/6921300-the-best-camera-is-the-one-that-s-with-you ''The Best Camera Is The One That's With You''] is a book by photographer {{w|Chase Jarvis}}, celebrating mobile phone cameras, not for their technical quality, but rather for the fact that people usually [[1235|have them when interesting subjects appear]]. This advice is often given to novice photographers; sometimes phrased as, "The best camera is the one you use most." A cheap camera is better than an expensive professional camera if it is more often with the photographer, for example if it is light-weight enough to be carried on hiking trips. A fancy expensive camera that isn't available to use is of no value for taking pictures.

In this case, however, "the best camera" refers to the {{w|James Webb Space Telescope}} (JWST), the spacecraft depicted in the third panel, which cost $10 billion—[https://screenrant.com/james-webb-space-telescope-cost-how-much/ $9.5 billion over budget]—and was [[2014: JWST Delays|fifteen years late]]. It can be considered a camera because it takes pictures, and it's the best {{w|space telescope}} to date in terms of {{w|aperture}} size and thus {{w|angular resolution}}.[https://astronomy.stackexchange.com/questions/26373/relation-between-angular-resolution-and-aperture] The first pictures taken by the telescope were released on 11-12 July 2022, a few days before this comic was published.[https://www.nasa.gov/webbfirstimages] The pictures from JWST show objects as they were [https://webbtelescope.org/contents/media/images/2022/035/01G7HRYVGM1TKW556NVJ1BHPDZ as much as 13.1 billion years ago,] which is unprecedented by space telescopes, although {{w|HD1 (galaxy)|further objects}} have been identified by terrestrial telescopes. The telescope has [https://www.stsci.edu/jwst/instrumentation three instruments that can act as "cameras" for imaging,] a fourth {{w|optical spectrometer|spectrometer}} instrument, and many dozens of {{w|optical filter}}s. Because the telescope can only take infrared photographs invisible to the human eye, [https://jwst-docs.stsci.edu/files/97978094/97978104/1/1596073152120/NIRCam_filters_modules.png each of the filters has been assigned a standardized visible color] to convert images for viewing. However, astronomers are encouraged to use [https://www.youtube.com/watch?v=-dmiS_6YrGU&t=449s other color schemes] when observing a limited portion of the filters' range or rendering {{w|interferometry}},[https://jwst-docs.stsci.edu/jwst-near-infrared-imager-and-slitless-spectrograph/niriss-observing-modes/niriss-aperture-masking-interferometry][https://jwst-docs.stsci.edu/jwst-near-infrared-camera/nircam-observing-modes/nircam-coronagraphic-imaging][https://jwst-docs.stsci.edu/jwst-mid-infrared-instrument/miri-observing-modes/miri-coronagraphic-imaging] and to [https://www.youtube.com/watch?v=sNJR3lenz1I&t=293s convert very distant objects to their original color] from {{w|redshift}}ed infrared when possible. The capabilities of the JWST are likely to soon answer many difficult astronomical, astrophysical, and [[2643: Cosmologist Gift|cosmological]] questions that had been previously undecidable, including important questions about the {{w|biosignature}}s of {{w|exoplanet}}s.

The title text references {{w|Lagrange Point|Lagrange Point 2}} (L2). The Lagrange Points are five locations corresponding to stationary regions of the {{w|restricted three-body problem}}, in which one of the bodies is much less massive than the other two. A low-mass body in one of those five locations will remain roughly stationary relative to the other two bodies with very little fuel needed for trajectory corrections. In this case, the JWST orbits around the L2 point of the Earth-Sun system with a period of about 6 months, [https://space.stackexchange.com/a/57378 rather than being stationed exactly at it,] to avoid shadows from the Earth and Moon that would cause harmful temperature and power variations.[https://ntrs.nasa.gov/citations/20190028885] Thus it avoids the problem with the {{w|Hubble Space Telescope}} caused by orbiting the Earth, allowing only a short observation window per orbit, with only about 55 minutes of each of its 95 minute orbits usable for observations not sufficiently above or below its orbital plane.

Talk:2659: Unreliable Connection

2022-08-17T00:42:01Z

172.70.206.95: Revise

I don’t think this has anything to do with teleconferencing. Am I missing something? [[Special:Contributions/172.70.214.81|172.70.214.81]] 22:46, 15 August 2022 (UTC)
:Yes. The impliction is that people are expecting you to be available for online communications, and you can use the unreliable Internet connection as an excuse to get out of it. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 22:51, 15 August 2022 (UTC)
::I think it's more about communication in general. He doesn't want anybody calling him or sending him emails, so by saying he has an "unreliable" connection people might assume it will be hard to get in touch with him.
:::Back in the day, email was usually configured so that it could easily overcome such unreliability, and it's still doable,[https://discourse.mailinabox.email/t/running-from-home/6459/7] but today email for most people is a web or local client-server app, as opposed to a local mail store in a peer-to-peer app. Even people in urban areas can suffer unreliable internet, when squirrels or backhoes gnaw through data cables, copper theives strike, or 5G mind control base stations are congested. [[Special:Contributions/172.70.210.143|172.70.210.143]] 23:45, 15 August 2022 (UTC)
:::This could equally cover other instant communication methods where your availability is advertised (e.g. Whatsapp). It could also be about alleviating the social pressure the subject feels to continuously check and immediately respond to messages (including emails), because the immediacy is already hindered by the spotty connection (cf the standard "I will have limited access to email" out of office line, which gives the account owner psychological permission to check it infrequently). [[Special:Contributions/172.70.85.5|172.70.85.5]] 09:02, 16 August 2022 (UTC)

According to a PhET simulator (https://phet.colorado.edu/sims/html/plinko-probability/latest/plinko-probability_en.html) for this situation, the ideal standard deviation is 1.732 and ideal mean is 6. I don’t feel like doing the calculations :P [[Special:Contributions/172.70.211.134|172.70.211.134]] 23:34, 15 August 2022 (UTC)
:If we assume 50-50 for each bounce, the probability that internet is off will be about (11 choose 3)/(2^11), or 8%.--[[User:Account|Account]] ([[User talk:Account|talk]]) 23:51, 15 August 2022 (UTC)
::My first thought was, why so complicated? ''If'' each of the twelve switches is equally (and solely) likely to be struck by each ball, it's (100/12)% of the time, or 8⅓%.
::Although the equal-chance is wrong, so you're definitely doing "end up with exactly 7 bounce rights and 3 bounce lefts, but in any combination" or similar are you? I'd have summed it differently, though. And not sure where the choose ''3'' comes in... Just one bounce left off any row-end pin 11 sends to 11 if all others bounce right. Three bounces left hits switch 9, not eight. If I'm counting correctly. Or am I doing telegraph-poles/wires miscounting?
::Too early in the morning for me to untangle. The only thing I'm sure about is your division by 2^11 (how many total paths there are to get down). [[Special:Contributions/172.70.91.78|172.70.91.78]] 05:00, 16 August 2022 (UTC)
:::Me again. I hadn't checked that the transcript (which said it was switch #8) was correct. Have now, and found it to be wrong. Have hence also just corrected the Transcript. So I'm gonna assume your 11-choose-3 is entirely correct after all. ;) [[Special:Contributions/172.70.91.78|172.70.91.78]] 05:08, 16 August 2022 (UTC)

To whomever did [https://www.explainxkcd.com/wiki/index.php?title=2659:_Unreliable_Connection&diff=292862&oldid=292861], doesn't [https://drops.dagstuhl.de/opus/volltexte/2018/8817/pdf/LIPIcs-FUN-2018-26.pdf] prove that symmetrical configurations nearly identical to those shown can produce uniform distributions? They seem to show it's just a matter of horizontal pin spacing. However, I for one can not verify the proof, which uses unusual (novel?) non-Unicode math notation, and a fairly opaque method of proof. [[Special:Contributions/172.70.211.134|172.70.211.134]] 00:07, 16 August 2022 (UTC)
:Not sure, but [https://ja.wikipedia.org/wiki/%E9%87%98%E8%AA%BF%E6%95%B4 this Japanese Wikipedia article] is fascinating. [[Special:Contributions/172.70.206.213|172.70.206.213]] 01:51, 16 August 2022 (UTC)
:Please see section 3.5 on pp. 16-18 of the currently first reference [https://arxiv.org/pdf/1601.05706.pdf]. I am particularly intrigued by, "Open Problem 2: Is every uniform distribution of output probabilities of the form 1/2k constructible by a 50-50 Pachinko?" on p. 18. However I haven't dived in enough to even know where the parentheses are supposed to be in that expression, yet. [[User:Liv2splain|Liv2splain]] ([[User talk:Liv2splain|talk]]) 17:27, 16 August 2022 (UTC)
: Good question! https://ibb.co/sRwGwB9 don't look triangular, but it seems the proof might suggest much more triangular solutions. Worth thinking about! [[Special:Contributions/172.69.33.115|172.69.33.115]] 21:24, 16 August 2022 (UTC)

What is the chance that the ball will bounce off the first pin, go down the outside of the pins and miss all the switches?
:Probably quite high if it's a bouncy ball. With idealized physics though it'd just hit the leftmost/rightmost switch. [[Special:Contributions/172.70.254.127|172.70.254.127]] 00:45, 16 August 2022 (UTC)

I would describe the device as a https://en.wikipedia.org/wiki/Galton_board. [[Special:Contributions/172.70.230.109|172.70.230.109]] 00:30, 16 August 2022 (UTC)

I was watching the photo and hover-over text and the image disappeared and "Unreliable Connection" showed up in its place. I don't know how often this happens.
: Very neat if not a fluke! Can anyone replicate this experience on https://xkcd.com ? [[Special:Contributions/172.70.211.134|172.70.211.134]] 14:21, 16 August 2022 (UTC)

"An added source of humour is that Randall could likely achieve the same effect by looking through the router's settings - which most modern ones have a feature to turn on and off at scheduled times - or via purchasing a smart power strip." But by using these other methods, the connection would still be reliable. If it goes out at regular or pre-scheduled intervals then you know when it will be available or not, hence reliable. I think the joke here is that the contraption does in fact make the connection unreliable. [[Special:Contributions/172.70.114.77|172.70.114.77]] 14:18, 16 August 2022 (UTC)

:(Edit conflicted by at least the above, but my answer to the same question...) From a user POV, unless they happen to know that at 11:53 each day (and 12:14, 15:02, 15:07, 16:31, etc...) the scheduler disables tracfic for one (or two, or three) minutes, it is still unreliable, if ultimately predictable ''once you know'' the schedule, having seen it go round a few times and taken note. Similarly a timered power-strip could be used (or even several, in serial, the two or three daily interventions by the first also stopping and delaying the subsequent strips' interventions, making their timings uneven, further down the chain) and until you got the pattern it might as well be 'random', not entirely deterministic. (I'm wondering about some OR-gate-like/etc implementation, so power can pass by at least one parallel timer-shut-off to maintain power at the lower levels while ''some'' mid-way timers get depowered and thus 'shuffled' in interesting ways, and the resulting single output is governed by an intricate multi-dependent set of routes, but I bet an electrician would be wary about wiring that up...)
:You could hack (or patch) the management firmware to be a bit more (pseudo)random about it, though it would still be pseudorandom LFSR/Xorshift with a (long) repetition cycle.
:Or make it dependant upon an external factor (if the modulo 12 of the cumulative sum of all observed packet-destination IPs is zero, shut off for the five times the prior modulo 12 test value, in seconds..?), but that's ''practically'' the pachinko solution but with software hacking rather than hardware-making/hacking as per the comic.
:More effort is needed to make it ultimately unpredictable, but it can still be considered unreliable if it goes out just when you 'want' it.... [[Special:Contributions/172.70.85.5|172.70.85.5]] 15:02, 16 August 2022 (UTC)

For real though, isn't this kind of a good idea? [[User:Fephisto|Fephisto]] ([[User talk:Fephisto|talk]]) 14:34, 16 August 2022 (UTC)
:Talk to edtech people in the {{w|MOOC}} space and they will tell you asynchronous is worth it, but talk to people who study educational quality factors like time to receive answers to unanticipated questions, and they will have different ideas. [[User:Liv2splain|Liv2splain]] ([[User talk:Liv2splain|talk]]) 14:44, 16 August 2022 (UTC)

Does anyone have an openWRT (or other) implementation of this feature yet?
:You can induce it on stock firmware without reflashing, but you need to know the parameters like how often balls come out of the hopper, and what exactly the on/off switches do. As pseudocode:

In this comic, [[Randall]] solves the social problem of demands for {{w|synchronous conferencing|synchronous teleconferencing}} with a deliberately less than optimal internet device that causes {{w|Asynchronous communication|asynchronous}} methods of communication to be relatively more reliable and efficient for personal use. The device appears to be an automated version of {{w|Jin Akiyama}}'s mathematical {{w|pachinko}} machine[https://arxiv.org/pdf/1601.05706.pdf] with a series of eleven "on" and one "off" switches at the bottom to be pressed by falling balls. This is funny because such a device could likely much more easily be implemented in the {{w|firmware}} of the internet or WiFi {{w|modem}} or {{w|Router (computing)|router}}s. It's not clear whether the switches merely interrupt the connection momentarily or control power to the modem, which would involve a much longer booting sequence.

Assuming the machine is symmetric, the probability of a single ball hitting the "off" switch is 165/2048, or about 8%.
We don't know the frequency with which new balls are dropped, so we can't estimate the frequency with which the device is likely to trigger {{w|Session Initiation Protocol}}, {{w|Transmission Control Protocol}}, or similar {{w|Timeout (computing)|timeout}} conditions that would likely close synchronous {{w|VOIP}}, video conferencing, and e.g. {{w|VRChat}} connections. Even if such connections were to survive the induced service interruptions, the {{w|application layer}} call or teleconference quality would suffer during them. The device may cause interruptions rarely enough that the connection is usable for casual purposes, but the user can still reasonably claim that it's unreliable to get out of online obligations.

The title text reflects on the mild paradox that a nominally unreliable internet connection has advantages for those whose communication schedules, volume, or style preferences make synchronous teleconferencing less practical, as indicated by the reviews for the new vacation spot.
