==Explanation==
{{incomplete|Created by a BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
In this comic, [[Black Hat]] is presenting a refridgerator to [[Cueball]], claiming it only uses 3 kWh per day. This is a commonly used, but uncancelled unit: kiloWatts x hour / day contains two units of time, which can be cancelled (24h = 1d), yielding 0.125 or 1/8 kW.
Cueball answers by asking whether the refridgerator would fit in his kitchen, since the ceiling is only 50 gallons per square foot high, which is also an uncancelled unit, as gallons can be transformed to cubic feet, which can be divided by the square feet, yielding a ceiling height of around 203.7 cm, or around 6 feet 8 inches.

White Hat is trying to sell a refrigerator to Cueball. In doing so, he touts the power draw of the unit as "three kilowatt-hours per day". But "day" and "hours" are both units of time. "Per" indicates division, so this could be written as (3 kW-h / d), or (3 kW-h / 24 h). Identical units in the numerator and denominator of a fraction cancel out, so it could also be written as (1/8 kW), or one-eighth of a kilowatt (or 175 watts), a typical power draw for a fridge running between 6 and 8 hours a day.

3002: RNAWorld

LtPowers: /* Explanation */ Italicize film titles

}}

==Explanation==
{{incomplete|Created by ELSA MAKING RNA - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic conflates {{w|biology}} and {{w|Disney World}}. Disney World is one of a franchise of theme parks with attractions based on various {{w|Walt Disney Company|Disney}} movies, while {{w|RNA world hypothesis}} is a proposed origin of life, in which RNA acts both as the genetic material and {{w|Ribozyme|the enzymatic machinery needed to copy it.}}

{{w|Ariel (The Little Mermaid)|Ariel}} is the titular character from {{w|The Little Mermaid (1989 film)|''The Little Mermaid''}}. In the film she likes to collect human artifacts; the comic replaces this with collecting {{w|nucleotides}}, the basic building blocks of {{w|DNA}} and {{w|RNA}}.

{{w|Ratatouille (film)|''Ratatouille''}} is a film about a French rat named Remy who dreams of becoming a gourmet chef. The comic conflates the soup that a chef might create for patrons to eat with "{{w|primordial soup}}", the environment that's believed to have existed on the early Earth when the processes of life began.

{{w|Elsa (Frozen)|Elsa}} is one of the lead characters from the {{w|Frozen (2013 film)|''Frozen''}} movies. In the film she has the magical ability to control ice and snow, and she used this power to make the snowman {{w|Olaf (Frozen)|Olaf}} come to life. The comic equates this with the original {{w|abiogenesis|emergence of life on Earth}}, or life from non-life, through {{w|ribozyme}} synthesis. Ribozymes are RNA molecules that, similarly to enzymes made of protein, catalyze biochemical reactions, such as the splicing of RNA during gene expression.

The title text continues this by saying that since Elsa's ability is based on ribozymes, Olaf's machinery of life must be based only on RNA, not DNA. This fits in with the theme of RNA World. Olaf generally appears to be (by mass) mostly just snow but, in common with various ideas about {{w|Comet nucleus#%22Dirty snowball%22|the makeup of cometary ice}} (and the role played by them in 'seeding' the young Earth with organic molecules), might well be thoroughly imbued with carbon-rich compounds ''other'' than those inherent in his carrot nose, coal buttons, and basic twig/stick elements. "Canonically" refers to {{w|Canon (fiction)|fictional canon}} (in this case Disney fiction), "the body of works taking place in a particular fictional world that are widely considered to be official or authoritative."

2929: Good and Bad Ideas

}}

==Explanation==
{{incomplete|Created by a BLOOD FOR THE BLOOD GOD- Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This is a scatter plot comparing how good an idea sounds to how good the idea actually is. For example, leaded gasoline sounds like a good idea due to the anti-knocking effects, but is actually a bad idea due to lead toxicity. Fake prank fire extinguishers however sound bad and are bad as they can result in a dangerous situation in an emergency. Putting mold on infections sounds like a bad idea, but this could be referring to Penicillin, an antibiotic.

The title text combines leaded gasoline and a fake prank fire extinguisher into something that is worse than either. Not only is the fire extinguisher fake, it also releases flammable material onto the fire, and there is the additional lead toxicity.

{| class="wikitable"
|-
! Idea !! What it means !! How good it sounds !! How good it actually is !! Explanation
|-
|Leaded Gasoline||Adding {{w|Tetraethyllead|tetraethyl lead}} to gasoline to reduce noise and/or increase performance||++||---||Leaded gasoline was introduced in the early 1920s to eliminate engine knocking and greatly increase fuel efficiency and engine performance. Lead, however, is toxic. Burning the leaded gasoline in an engine releases the lead in the air. This is bad, and was known to be bad at the time, which is why there was an extensive PR campaign by oil companies to prove the alleged safety of the new product which, broadly speaking, succeeded up until the 1970s.
|-
|Bloodletting||Releasing "bad blood" from the veins||---||---||You need (most of) your blood.{{Citation needed}} Bloodletting has been performed as a medical procedure for at least 2000 years until it was considered pseudoscience from the 19th century, when the harmful effects became known. The idea was to withdraw blood to balance the body's "humors". Nowadays {{w|phlebotomy}} is only used therapeutically in a small number of cases, such as hemochromatosis (too much iron in the body).
|-
|{{w|Asbestos}}||Mineral which does not burn and is good insulation, isolation, and fire-retardant||+++||---||Asbestos was used extensively in buildings throughout most of the 20th century. Sadly the microscopic fibers which make up asbestos greatly increase the risk of cancer when inhaled.
|-
|Extension cords with prongs on both ends||allows easy connection between 2 female connectors||0 (neutral)||---||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video].
|-
|Stair Kayaking||Riding down a flight of stairs in a {{w|kayak}}||--||---|| Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, rides the kayak down the stairs. This poses significant easily foreseeable risks of injury or death, as well as being very bad for the kayak, which is designed to ride on water, not concrete.
|-
|Fake prank fire extinguishers||||---||---|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds very dangerous and potentially life-threatening for many people, and it would, in fact, be highly dangerous. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.
|-
|Always saying what you think||...regardless of the feelings of others or other considerations||++||--||Openness and honesty are seen as positive character traits in people. However, taken to the extreme of ''always'' telling people what you think about them, they can lead to awkward or unpleasant situations. It may harm your relationship with the other person if they don't like what you think, or they may reply without concern for ''your'' feelings or other considerations. Keeping negative thoughts to yourself or telling "white lies" can be considered a better alternative in some situations.
|-
|Replying to spammers||Clicking on the "Reply" button from spam mails and writing (and sending) a reply (or worse, clicking on the links in these mails)||--||--||At best, you confirm your email address and identify yourself as someone likely to respond to such unsolicited messages, and so encourage the spammers to deluge you with even more messages. At worst, the spammer may use your correspondence to extract sensitive information about you, or make you victim to a scam.
|-
|Solar cars||Having {{w|Solar panel|solar panels}} on the car's surface (mostly hood and roof) for power generation||+++||-||Cars require large amounts of energy in short periods of time and portable solar panels generally do not produce enough, nor are they as efficient as fixed installations on the power grid.
There are competitions for solar powered cars, though, like the {{w|World Solar Challenge}}.
|-
|Heelies||{{w|Heelys}} are shoes with a inline skate wheel embedded in the sole, at the heel. ||+||-||Heelys allow the wearer (usually children) to shift between normal walking and rolling like a roller skate. This sounds like fun but has led to numerous injuries.{{Actual citation needed}}
|-
|Prequels||A work of fiction (mostly movie) telling the "story before the story" of another work of fiction.||+++||-||More of a good story sounds great on the surface, but the constraints of a prequel's ending needing to create the starting conditions of the original work often precludes organic development and causes contrived plots.
|-
|Transitions® Lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses, which get darker (like sunglasses) in bright light.||+||-||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the exposure is removed. The advantage is that wearers of glasses don't need to buy separate (prescription) sunglasses. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, perhaps in a forest or when driving. Also, car windscreen filter out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark and in cold weather they might stay dark for too long.
|-
|Cutting pizza in squares||Cutting (a presumably round) pizza in squares||-||-||Most people cut pizza into wedges and hold it by the crust. Cutting it into squares allows for more pieces to be shared, but pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. There will also be lots of leftover tiny pieces. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only into four squares, some people will end up with a higher crust-to-topping ratio than others.
|-
|{{w|Project Orion (nuclear propulsion)|Project Orion}}||Study by the U.S. government looking into nuclear pulse propulsion for spacecraft.||---||-||Using repeated nuclear explosions to generate motion sounds bad for both the spacecraft and everything else, especially with a ground launch, but there are ways to address a lot of the concerns, so it isn't as bad as it sounds. Project Orion's theorized specific impulse and thrust would also be far higher than anything chemical rockets can accomplish. The efficiency of Project Orion is extremely low, however.
|-
|Soup||Soup||0 (neutral)||0 (neutral)||Soup is probably one of the oldest foods created by prehistoric cooks. Many people enjoy it, though some consider many soups somewhat lacking as a meal on their own, or bland.
|-
|Combo washer dryers||A device which combines washing machine and laundry dryer into one device||+++||+||Better at space efficiency, but worse at each task than separate devices.
|-
|Cutting sandwiches diagonally||Cutting sandwiches diagonally||+||+||Generally regarded{{Actual citation needed}} as the structurally superior way to slice a sandwich, providing better support in the hand and fewer all-crust bites.

The important part is a composition of different species of bacteria that compromise the biome. Sometimes it may be necessary to completely sterilise the gut and then take a sample of a healthy biome from another person. A sample is enough as the bacteria will multiply. As long as the patient eats correctly, the microbiome after transplant should develop correctly.

It sounds bad because we tend to think of our feces as something gross, to be discarded. It is called fecal transplant as our feces contain about 50% of gut bacteria, but nowadays the sample usually takes the form of a coated pill that is applied rectally.

2924: Pendulum Types

| imagesize = 589x302px

}}

==Explanation==
{{incomplete|Created by CREEPING TENDRILS OF STARCH - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic shows and describes several {{w|pendulums}}. The first three are actual physics models, while the last one is made up for absurdity. This is a recurring format of xkcd comics, as shown in [[2289: Scenario 4]].

The simple pendulum consists of a joint, rod, and weight, and when released (inside a gravity field or other accelerating force), it swings in a regular fashion. The "period" of a pendulum is the amount of time it takes to complete one cycle, swinging back and forth. In a simple pendulum, the period is consistent, predictable, and depends primarily on the length of the pendulum (being largely independent of both mass and length of arc). This predictability makes pendulums useful in applications such as timekeeping, where the earliest accurate clocks (such as a {{w|grandfather clock}}) made use of pendulums as regulators.

The {{w|double pendulum}} consists of 2 joints, 2 rods, and a weight, and when released, it swings in a {{w|chaos theory|chaotic fashion}}. Interestingly, this follows by the mathematical definition of chaotic, being that small changes in initial conditions result in vast differences in end results. This pendulum is thus nearly unpredictable, and due to this chaotic nature, real life applications are very limited.

The {{w|inverted pendulum}} consists of a simple pendulum that is placed upside down, with some apparatus underneath vibrating it vertically to keep it upwards. If left unpowered (or improperly controlled from positional feedback) it will fall, hence the "unstable" part. (The comic, however, appears to depict {{w|Kapitza's pendulum}}, a powered version that does not rely upon monitoring and feedback control.)

The nightmare pendulum appears to be an inverted double pendulum, with an additional uninverted pendulum swinging within its much more substantial weight (which is also adorned with archaic/mystical symbols). The comic claims that this pendulum summons {{w|Maxwell's demon}}, jokingly implying that Maxwell’s demon is an actual entity. In fact, Maxwell's demon is a thought experiment in which a being (the demon) is posted at a tiny door between two gas vessels. It lets only slow-moving (cold) gas molecules move in one direction, and only fast-moving (hot) ones in the other direction. One vessel would thus gradually become hot and the other cold, appearing to violate the {{w|second law of thermodynamics}}. However, it doesn't, but the thought experiment has stimulated much discussion since it was first proposed by {{w|James Clerk Maxwell}} in 1867.

The title text continues this joke explicitly, by referencing a real paper titled [https://pubs.rsc.org/en/content/articlelanding/2014/sm/c4sm00265b Vibro-levitation and inverted pendulum: parametric resonance in vibrating droplets and soft materials] and implying that the paper ties the [https://www.youtube.com/watch?v=3zoTKXXNQIU "creepy fingers"] produced in this way to Maxwell's demon. The paper only actually suggests that the phenomenon is related to inverted pendulum dynamics. This gives a humorous example for the abuse of citations. Technically, the cited reference only supports the claim immediately before it, that the behavior of a cornstarch-water mix (also known as {{w|Non-Newtonian fluid#Oobleck|oobleck}}) can be modeled as inverted pendulums. But by proximity the reference also seems to support the part about Maxwell's Demon. The illusion is helped by the description of the cornstarch as creepy, which is added in the beginning without any visible separation from the actual content of the citation.

2786: UFO Evidence

2023-06-08T12:26:12Z

LtPowers: /* Explanation */ clarify geographical context

{{comic

| imagesize = 340x422px

==Explanation==
{{incomplete|Created by an ANATOMICALLY INCORRECT CAT WITH A NEED THAT WILL NOT BE SATISFIED. Do NOT delete this tag too soon.}}

[[White Hat]] (presumably a [[wikipedia:Ufology|ufologist]]) accuses [[Cueball]] of being unwilling to listen to his claims for extraterrestrial life. UFO stands for "unidentified flying object" but is used in common parlance to mean a spaceship carrying beings from another planet. The term "Unidentified Anomalous Phenomena" (''UAP'') has been more recently adopted in United States official investigations (that might wish not to be instantly associated with "little green men" and their "flying saucers") and was in the news during the weeks before this comic due to the coverage of official releases (and U.S. Senate hearings) regarding the official monitoring of observation reports. In these, various supposed sightings were given mundane explanations, while a few others were not but were generally considered insufficient proof of extraterrestrial visitations. A devout UFO-believer is likely to be somewhat disappointed by this, having more personal willingness to believe that the more ambiguous sightings are truly flying saucers. And possibly even that some or all of the 'explained' ones are being officially misinterpreted or misrepresented in a denialist manner for the government's/authorities' own purposes.

Cueball counters this common pushback by admitting that he once spent an entire day trying to confirm the existence of a version of [[wikipedia:Cats_(2019_film)|the 2019 film adaptation of ''Cats'']] which allegedly gave the eponymous anthropomorphic felines anatomically-correct rear ends.

The ''Cats'' movie was widely panned, in part because of the unappealing design of its CGI cat characters. On March 18, 2020, Twitter user @jackwaz claimed a friend of a friend had been hired as a VFX artist to "[https://www.avclub.com/world-unites-over-need-for-cats-producers-to-releaseth-1842396923 remove CGI buttholes]" from the digital cats, meaning that there was a version of the movie where the characters all had anatomically correct feline anuses depicted. This caused social media users to start petitioning for official confirmation of "the butthole cut," which Universal Studios has so far declined to acknowledge.

Cueball was apparently willing to lend enough credence to such an absurd and entirely inconsequential claim to spend time researching it. His suggestion is that if he was willing to invest that effort on the basis of such flimsy and meaningless evidence, the fact that he won't look in to White Hat's claims means that they must be even more worthless. The only reason why most scientists would reject such claims is a total lack of even faintly compelling evidence. As [[Cueball]] points out, if someone ever managed to present evidence of alien life that was even slightly plausible, many scientists would enthusiastically spend a great deal of time and effort trying to verify it.

The comic probably pertains to U.S. Air Force veteran and former {{w|National Geospatial-Intelligence Agency}} member [https://www.newsnationnow.com/space/ufo/lawmakers-react-to-whistleblowers-ufo-claims/ David Grusch], who is seeking whistleblower status for his claims that the U.S. government is hiding crashed alien spacecraft and corpses.[https://news.ycombinator.com/item?id=36216745] It continues a common XKCD theme of mocking dubious claims, including [[Alien Observers|UFOs]], [[Health Drink|pseudoscience]], [[The Economic Argument|paranormal phenomena]], and [[Conspiracy Theories]], which are presented without plausible or verifiable evidence. [[Randall]]'s general attitude toward these claims is that, if any of these things were true, we would expect evidence for them by now. Complaints that there is evidence, and scientists won't look at it are utterly implausible, because such evidence would be of enormous interest to scientists, if it had even a hint of being plausible.

The title text may refer to [https://phys.org/news/2015-01-aliens-tv.html the idea that aliens could be watching our old TV]. Because radio and television signals travel at light speed, aliens light years away could theoretically receive earth entertainment years after it was originally broadcast. The idea that they are learning about us from ''Cats'', which is thought of as {{w|List of films considered the worst#Cats (2019)|one of our worst films of all time}}, is not the view of humanity most people would want to present. Especially since they might ask for the butthole cut...

==Transcript==
:[White Hat, with his finger raised, is talking to Cueball.]
:White Hat: You scientists aren't willing to take my UFO evidence seriously!
:Cueball: I once spent a whole day trying to confirm the existence of a director's cut of ''Cats'' (2019) where the cats had anatomically correct CGI butts.

"March Madness" is the (trademarked!) colloquial name given to the {{w|NCAA Division I men's basketball tournament}}, the season-culminating college basketball tournament played each spring in the US. It's common for college basketball fans—and even people who pay no attention to the sport for 11 months of the year—to make guesses as to how the tournament will play out. They often compete against each other to see who in a group has the most accurate predictions.

The Y2K bug, or more formally, the {{w|year 2000 problem}}, was the computer errors caused by two digit software representations of calendar years incorrectly handling the year 2000, such as by treating it as 1900 or 19100. The {{w|year 2038 problem}} is a similar issue with timestamps in {{w|Unix time}} format, which will overflow their {{w|Signed number representations|signed}} 32-bit binary representation on January 19, 2038.

While initial estimates were that the Y2K problem would require about half a trillion dollars to address, there was widespread recognition of its potential severity several years in advance. Concerted efforts among organizations including computer and software manufacturers and their corporate and government users reflected unprecedented cooperation, testing, and enhancement of affected systems costing substantially less than the early estimates. On New Year's Day 2000, few major errors actually occurred. Those that did usually did not disrupt essential processes or cause serious problems, and the few of them that did were usually addressed in days to weeks. The software code reviews involved allowed correcting other errors and providing various enhancements which often made up at least in part for the the cost of correcting the date bug.

It is unclear whether the 2038 problem will be addressed as effectively in time, but documented experience with the Y2K bug and increased software modularity and access to source code has allowed many otherwise vulnerable systems to already upgrade to wider timestamp and date formats, so there is reason to believe that it may be even less consequential and expensive. The 2038 problem has been previously mentioned in [[607: 2038]] and [[887: Future Timeline]].

This comic assumes that the 38 years between Y2K and Y2038 should (or must) be split evenly between recovering from Y2K and preparing for Y2038. That would put the split point in 2019 (specifically, January 10, 2019). The caption points out that it's now (2022) well past that demarcation line, so everyone should have completed their "Y2K recovery" and begun preparing for Y2038. It is highly unlikely that there are more than a very few consequential older systems that still suffer from this bug, and systems built since already handle years after 1999 correctly. There's also no reason any developer should have waited until 2019 to start preparing for 2038.

The title text refers to replacing the 32-bit signed Unix time format with a hypothetical new 33-bit signed {{w|Integer (computer science)|integer}} time and date format, which is very unlikely as almost all contemporary computer data structure formats are allocated no more finely than in 8-bit bytes. Taking 20 years to develop and implement such a format is not entirely counterproductive, as it would add another 68 years of capability, but it is far more counterproductive than upgrading to the widely available and supported 64-bit Unix time replacement format and software compatibility libraries.

They probably worked together on the project after Cueball's idea. Even if not, it has been common that the professor shared the prize (or took it all) if one of their students (especially woman students) got the idea.

2556: Turing Complete

2021-12-18T14:26:06Z

LtPowers: "overflown" is the past participle of "overfly", not of "overflow". https://en.wiktionary.org/wiki/flown

{{comic
| number = 2556
| date = December 17, 2021
| title = Turing Complete
| image = turing_complete.png
| titletext = Thanks to the ForcedEntry exploit, your company's entire tech stack can now be hosted out of a PDF you texted to someone.
}}

==Explanation==
{{incomplete|Created by a NATION-STATE THAT CAN RUN DOOM, AND CRYSIS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

A {{w|Turing machine}} is a theoretical form of computer (as an idealised thought exercise) that has an infinite tape of symbols and can act upon and change these values as it moves up and down this tape according to specific deterministic rules.

This very simple machine can be shown to do every computational task that what we think of as a "computer" can do, given the right setup and enough time. Something that is {{w|Turing complete}} is able to act as a Turing machine, though generally with the limitation of having a finite tape, and this means it is also able to do basically every computational task.

While many pieces of hardware and software are supposed to be Turing complete (even Excel, as previously pointed out in [[2453: Excel Lambda]]), this comic implies that this was not what it was designed for. Whatever [[Ponytail]] has been referring to is not shown, but it seems to be an anecdote about how something seemingly too simple and/or specialised to exhibit such a computational equivalence has been discovered to actually be that capable.

With complex processors now installed in many household items, including large kitchen appliances like dishwashers, the possibility is raised that someone has 'hacked' such a device to do the same computational work as an actual games console. Alternatively, if hackers working on behalf of a foreign government have discovered an undetected exploit in a nation's cyber-defenses, the fact that a piece of infrastructure accessible to outsiders is Turing-complete (and could thus potentially be used to execute arbitrary code) may come as a very unpleasant surprise to the nation being attacked.

The {{w|FORCEDENTRY|ForcedEntry}} exploit is a way that was discovered to allow {{w|PDF}} files to force malware onto various devices. In particular, the exploit [https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html involves constructing a simplistic virtual CPU] within one of the PDF renderer's decompression functions out of individual logic operations on pixels in an overflowed output buffer. In the title-text it is suggested that this mechanism can be used for what might be more legal and practical purposes, although this might be up to some interpretation depending upon who has the right (and permission) to do what.

A {{w|Solution stack|tech stack}} is one shorthand way of describing the way an integrated grouping of communicating software packages provides everything from the deepest data handling (even as low-level as an Operating System itself) to the user interface. All of these will normally be on a computer (or possibly many of them, whether locally or distributed worldwide) and if a sufficiently functional surrogate system is capable of emulating this (computing what the original computer(s) would do) then it can be considered to effectively ''be'' the same stack of technology and duplicate or replace the originals.

More references https://mathworld.wolfram.com/RandomWalk.html

Someone's gotta point out that "walking randomly on a grid, never visiting the same square twice" would rapidly trap you in a corner (even the example has a 50/50 chance of that happening on the next move) [[Special:Contributions/172.70.130.125|172.70.130.125]] 04:29, 16 October 2021 (UTC)

Not if it's an infinite grid.

I think there's two different ways to interpret the question - as a uniform random element of the set of all non-self-intersection NxK length paths, in which case it's fine, or as a path defined by a random walk in which moves onto your own path are not allowed, which doesn't seem well defined, since you might end up in a situation where you are surrounded by your own path and cannot continue for all NxK steps.

I'm not sure the current explanation, that the newscaster believed the biblical quote by mistake, is necessarily the correct one. The way I read this, as someday it should happen that the events described in Revelation REALLY DO START TO OCCUR, there will still be newsies who entirely miss the point, and keep producing random oblivious clickbait stories by 'interviewing' random twitter users. Alternately, if modern-day newscasters traveled back in time, to when the original Revelation was actually recieved and written, the same oblivious quoting without context could also occur.

I'm only familiar with 4th and 5th edition, but should the "Good/neutral/evil:" axis eplanation be changed to "selfless deeds or selfish deeds"? Good and evil are highly subjective ("One person's 'freedom fighter' is another person's 'terrorist'.") but at least in 5e the axis is explained as risking/sacrificing yourself for the benefit of others (Good) vs. sacrificing others for your own benefit (Evil). Also, the explanation of the CN character may benefit from dividing which parts of the explanation are "chatoic" vs "neutral". Finally the "lacking rhyme or reason" part of chaotic is highly debated within D&D circles. There are certainly people who play that way, but there are also others who feel that chaotic characters have just as much motivation and goals as a lawful or neutral character just that part of their motivation is to act contrarily to Tradition/Authority.

I once simply went through the Wikipedia article, which cited the second edition IIRC: ‘lawful’ means sticking to ''some'' code of conduct, whereas ‘chaotic’ is a pure opportunist or behaves randomly. ‘Good’ and ‘evil’ indeed mean selfless vs selfish deeds, but afaik in one of the official explanations ‘evil’ meant exercising authority over others—so all managers would be ‘evil’ automatically.

I think the Omnispace Classifier is meant to be a horrific Frankenstein amalgamation of the other 8 kinds of chart.

}}

==Explanation==
{{incomplete|Created by a [[User:DgbrtBOT|TRUE NEUTRAL BOT template]]. Needs explanations of each alignment chart, and probably some editing for clarity.}}

"Alignment" and "alignment charts" come from the the tabletop game ''{{w|Dungeons & Dragons}}''. Every character has an {{w|Alignment (Dungeons & Dragons)|alignment}}, which is a sort of a personality archetype or general description of morality. The most widely used alignment system was introduced in the ''{{w|Dungeons & Dragons Basic Set}}'' in 1977 and has been reused in many (but not all) subsequent editions of the game. This system uses two perpendicular axes, each axis having three words; the alignment of a particular character is a combination of one word from each axis (for a total of nine categories). The two axes are:
* Lawful/neutral/chaotic: this axis says whether a character is strongly devoted to, indifferent about, or categorically opposed to following the rule of the law.
* Good/neutral/evil: this axis says whether a character is generally inclined to commit good deeds or evil deeds.
For example, a character's alignment can be "chaotic neutral". Being classified as "chaotic" means they're very prone to acting on emotions, they don't care what is allowed and what is prohibited, and their actions often go against things like tradition and chain of command. Being classified as "neutral" (on the second axis) means that their deeds and character are not strongly good nor evil; either they have a balance of both, or they rarely do anything that can be clearly labelled as one or the other. There are nine possible alignments - any combination of the two axes is allowed. A character with the "neutral neutral" alignment is called a true neutral.

The use of the term chaotic in a personality alignment context is different to the term in a physics concept. In physics, {{w|chaos theory|chaos}} refers to unpredictable outcomes following emergent behaviours that are sensitive to small changes in underlying conditions. Similarly, lawful can be considered to follow deterministic physical behaviours. Hitting pool balls with a pool cue is deterministic, it follows the deterministic Newtonian laws of motion. Hitting your opponent with a pool cue is chaotic, the end state of the ensuing brawl is unpredictable.

An alignment chart is a grid that divides the alignments, usually for the purpose of putting descriptions or particular characters on it. Alignment charts are frequently used as a [https://knowyourmeme.com/memes/mcdonalds-alignment-chart meme template], where humorous or absurdist things are organized into different alignments. In addition to the "classic" Dungeons and Dragons alignment chart, there are a number of variant alignment charts in use as meme templates. Many keep the three-by-three grid structure but replace the lawful-neutral-chaotic and good-neutral-evil axes with others, such as [https://knowyourmeme.com/memes/gay-bi-lesbian-distinguished-functional-disaster distinguished-functional-disaster vs. gay-bi-lesbian] and [https://knowyourmeme.com/memes/edgy-depressed-dumbass-bitch-thot-bastard edgy-depressed-dumbass vs. bitch-thot-bastard]. Some alignment charts use other systems of classification, like the [https://knowyourmeme.com/memes/mcdonalds-alignment-chart McDonald's alignment chart], which is a {{w|Ternary_plot|ternary diagram}}, a way of plotting data points by the relative proportions of three components in them on a triangular plot.

This comic claims to be a meta-alignment chart, where nine "alignment charts" are themselves sorted into the nine Dungeons and Dragons alignments, following the use of alignment charts to humorously classify abstract concepts. However, these "alignment charts" are mostly diagrams used in academic classifications, which are being treated as if they were blank meme templates. There are two levels of absurdity here: first, the idea of using these technical scientific diagrams to classify things they were never intended to, like fictional characters or how people bag their bread, and second, the conflation of chaos as a physics concept and an assigned moral weights as it applies to each of these classification systems.

The title text describes Randall's alignment as "lawful heterozygous silty liquid" which references the true neutral, neutral good, lawful good, and lawful neutral charts in the Alignment Chart Alignment Chart. Lawful is the left side of an alignment chart, heterozygous is the top right or bottom left of a Punnet Square, silty is the bottom right of a soil chart, and liquid is the top right of a phase diagram. As such, the title test describes Randall's alignment as between Lawful Neutral and Neutral Good on this chart.

{| class="wikitable"
!Alignment
!Chart
!Explanation
|-
|Lawful Good
|{{w|Soil texture|Soil chart}}
|This chart shows the USDA classification of soil types by their relative proportions of sand, clay and silt. The chart is a ternary diagram (very common in geology), so soils with more clay plot towards the upper corner, soils with more sand to the bottom left, and soils with more silt to the bottom right. This chart has been used humorously as an alignment chart ([https://www.reddit.com/r/PrequelMemes/comments/8wakd4/anakin_soil_reference_chart/ for example]) and may have been the inspiration for Randall to use scientific diagrams as alignment charts. In addition to being Lawful Good, this grid cell is also the upper left cell of the chart and will be read first, making it a good place to put this chart as a "jumping off point".
|-
|Neutral Good
|{{w|Punnett square}}
| Punnet squares are a visual method of determining what traits an organism might have based on the traits of the organism's parents. It relies on the principle that a trait is either dominant (indicated with capital letters) or recessive (indicated with lowercase letters). The exact combination of dominant or recessive genes that a child organism receives from their parents determines their traits. It is important to understand the terms "heterozygous", "homozygous" …” These refer to the pairs of alleles in an organism’s genotype, indicating mixed or same alleles, respectively. Randall later uses “heterozygous” in the title text. Note that it is possible for a phenotype to be expressed the same between some heterozygotes and homozygotes, e.g., persons with genotypes heterozygous ”Aa” and homozygous “AA” will both express blood type A.
Therefore, the Punnett Square is a good chart because it is both a simple and true geometric predictor of inheritance, but it tends to neutral because of complicating factors such as polygenic inheritance; these and other factors will cause genotypic frequency to deviate from expected 1:2:1 patterns.
|
|-
|Chaotic Good
|{{w|IPA vowel chart with audio|IPA vowel chart }}
|This chart shows the relationship between different vowels according to the {{w|International Phonetic Alphabet}}. As different vowel sounds are created by changes in different parts of the mouth, it can be considered chaotic.
|-
|Lawful Neutral
|Phase diagram
|A {{w|phase diagram}} shows the temperature and pressure points where a material changes phase. The diagram included is of an unknown material that has a solid, liquid, and gas phase. Phase diagrams are useful as the relationship is not always linear. For example, the air pressure of Mars is such that there is no temperature at which liquid water can exist. Water exists as ice until the temperature reaches a point where it sublimates directly into steam.

Phase diagrams follow the laws of physics, so are inherently lawful.
|-
|True Neutral
|Alignment chart
|All alignment charts are neutral unless humans contaminate them.
|-
|Chaotic Neutral
|CIE chromaticity diagram
|The {{w|chromaticity}} diagram is typically used to help determine a color temperature given the typical RGB intensities of light. Low color temperatures tend to be associated with 'softer' lights that are easier on the eyes, whereas 'higher' color temperatures are associated with 'harder' light that are perceived as brighter. Given that color temperature as defined by the chromaticity diagram has nothing to do with the actual color temperature of a blackbody as defined by Physics, it is chaotic. Also, the official specification for CIE is behind a paywall and defined by private organizations, making it more chaotic.
|
|-
|Lawful Evil
|Political compass
|Political Compass [https://www.politicalcompass.org/] separates out left-right thinking into economic and social political thought. For example, Gandhi and Stalin supposedly both had similar economic perspectives (collectivist) but radically different social perspectives (authoritarian vs libertarian).

As politicians make the laws, this is inherently lawful. Attempting to represent all politics in terms of two very general axes is a gross oversimplification, which is likely why it is listed as evil.

Like the USDA soil chart, the political compass has actually been [https://knowyourmeme.com/memes/political-compass used as an alignment chart], largely to mock the original political compass chart.
|-
|Neutral Evil
|{{w|QAPF diagram|QAPF rock diagram}}
|This diagram is used to classify coarse-grained felsic (low magnesium and iron) igneous rocks by the relative volumes of the minerals quartz, alkali feldspars, plagioclase feldspars, and feldspathoids in the rock. It consists of two ternary diagrams - quartz and feldspathoid minerals cannot coexist (they will react to form feldspars) so only three of these components will be in any given rock. Rocks in the upper triangle of the diagram contain quartz, with rocks with more quartz plotting closer to the top, while rocks in the lower triangle contain feldspathoids, with rocks with more feldspathoids plotting lower. Rocks closer to the left corner of the diagram contain more alkali feldspar and rocks closer to the right corner contain more plagioclase feldspar. The field on the diagram for granite is labeled in the comic, but each area outlined on the diagram has it's own rock name (monzonite, syenite, granodiorite, etc.). All the rocks that the QAPF diagram is used to classify look superficially like granite, but their chemistry, mineralogy, and origin differ.
The QAPF diagram and the names of the more obscure rock types on it can be somewhat arcane, which may be why it is considered evil here.
|-
|Chaotic Evil
|Omnispace classifier
|The other eight diagrams shown in this comic, squished together into one, with the shapes of the diagrams corresponding to those of the originals. Probably self-referential humour, in that the diagram created for this comic is considered to be chaotically evil.

The different double-headed arrows represent different levels of confidence in claiming this relationship between Cueball and the individuals in that "layer."

The way this is defined, you and your spouse both have the same set of siblings and siblings-in-law.

People actually complain cousins removed is hard to understand? When I first learned about it, my thought was actually: Wow, that is so much clearer than what we use in Dutch. In Dutch we use a prefix for each step its is removed so it can get wordy. A cousin would be "neef" a cousin once removed would be "achterneef" a 2nd cousin "achterachterneef". I think a 2nd cousin removed would then be "achterachterachterneef" and third cousins "achterachterachterachterneef". I'm not even sure that's how confusing it is. The English system is easy. Simply count up to the common ancestor (A), then down to the relative (R). Then you're (R-2)th cousins (A-R) times removed.
