==Explanation==&lt;br /&gt;
{{incomplete|Created by a THERMAL EXHAUST PORT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic is another in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}. This one is another analogy to how {{w|mRNA vaccines}} work, by creating inactive fragments of the virus to prime the immune system to be prepared to stave off the real thing. This is done in response to Cueball's question to the person vaccinating him, &amp;quot;Why would my body attack something it made itself?&amp;quot;, using elements of the film ''{{w|Star Wars (film)|Star Wars: Episode IV}}'' as an analogy.&lt;br /&gt;
&lt;br /&gt;
The analogy starts in the second panel, where the Rebel Alliance has retrieved the {{w|Death Star}} plans, conveyed by {{w|Princess Leia}} to General [https://starwars.fandom.com/wiki/Jan_Dodonna Jan Dodonna] (in ''Star Wars'', via {{w|R2-D2}} and some adventures, but shown as a simple handoff here). The Death Star is a space station the size of a small moon that has the power to destroy planets. In the film, the plans are analyzed to find a weakness in the enemy Death Star and destroy it; however, in this panel, the &amp;quot;Death Star plans&amp;quot; are passed down a line of people until they are interpreted as a construction assignment and are used to build a Death Star. In the analogy, the mRNA in the vaccine corresponds to the plans for the Death Star, the spike proteins (inactive COVID-19 virus fragments) that the mRNA code for correspond to the benign Death Star itself, and the cellular processes that build spike proteins correspond to the builders of the benign Death Star.  Just as merely having the plans on hand led to the Death Star being built, the mere presence of the mRNA in the cellular environment leads to it being translated, producing the viral protein.&lt;br /&gt;
&lt;br /&gt;
After Leia's Death Star has been built, it is positioned near a planet/moon. This Death Star is ''benign'': it only ''looks'' dangerous and isn't about to actually hurt anyone; the Death Star crew are Rebels, after all, and state that they don't have the laser wired up. The Rebels mobilize to destroy this benign Death Star because it looks like an enemy battle station, evidently not listening to the construction crew's transmissions. Analogously, immune cells cannot think {{Citation needed}} or directly communicate, basing their determination of friend from foe entirely on external chemical signatures. However, the Death Star operators are confused, because Leia (a member of the Rebels) had ordered its construction. The Rebels initially attack the surface of the benign Death Star, without much effect; Leia orders the factories to continue developing torpedoes and ships as they run out, presumably putting an extra workload on the factory workers and tiring them out, or at least diverting resources away from other projects. In the analogy, the Rebels correspond to the immune system's {{w|B cells}} and {{w|T cells}}, which mobilize to attack the spike proteins (the benign Death Star) made as a result of the vaccine, but are often ineffective at first. The body keeps producing these immune cells, trying many variants (many ways of attacking the benign Death Star) in an attempt to find one that works well against the spike proteins. This results in Cueball experiencing {{w|side effects}} from the vaccine, including soreness and tiredness, and he lies down and rests.&lt;br /&gt;
&lt;br /&gt;
After much effort on the Rebels' part, they find a weakness in the benign Death Star, a &amp;quot;thermal exhaust port&amp;quot; vulnerable to &amp;quot;proton torpedoes&amp;quot; that can destroy the Death Star. Firing a proton torpedo down the exhaust port destroys a Death Star very rapidly, compared to the initial, ineffective frontal assault on the surface. After this benign Death Star is destroyed, Princess Leia allows the fleet to stand down. In the analogy, the immune system (the Rebel Alliance) figures out a way to attach to the spike proteins (attack the benign Death Star) made by the mRNA vaccine; the immune system's {{w|antibodies}} (Rebel planners) now &amp;quot;know&amp;quot; how to recognize and destroy things that have these spike proteins — including SARS-CoV-2 virus particles (real, dangerous Death Stars).&lt;br /&gt;
&lt;br /&gt;
Later on, the vaccinated Cueball approaches White Hat, who is maskless, coughing, and presumably sick with COVID-19. Metaphorically, the rebels are attacked by a truly threatening Death Star, this time led by the enemy, {{w|Darth Vader}}, who says a quote from ''Star Wars'' (although this quote is actually spoken by the Emperor in ''{{w|Return of the Jedi}}''). By now, though, the Rebel Fleet led by Leia already knows the weakness of a Death Star, the thermal exhaust port, and quickly destroys Vader's Death Star. In the analogy, Cueball's immune system (the Rebel Alliance) is able to destroy dangerous SARS-CoV-2 virus particles (real, threatening Death Stars) because it knows about the virus's spike proteins (the thermal exhaust port). This is represented by Cueball not experiencing any suffering from COVID-19 (Vader's Death Star getting blown up immediately), and he goes on his way whistling merrily, perhaps to the tune of [https://www.youtube.com/watch?v=yixG8pfncOs The Throne Room/End Title] (from the ceremony celebrating the destruction of the Death Star).&lt;br /&gt;
&lt;br /&gt;
Cueball's wearing of a mask is in accordance with {{w|Centers for Disease Control and Prevention|CDC}} guidelines, which recommend continuing to wear a mask, practicing social distancing, etc. after getting the vaccine; doctors at CDC &amp;quot;don’t yet know whether getting a COVID-19 vaccine will prevent you from spreading the virus that causes COVID-19 to other people, even if you don’t get sick yourself.&amp;quot;[https://www.cdc.gov/coronavirus/2019-ncov/vaccines/faq.html] None of the vaccines available as of when the comic was posted are 100% effective at preventing infection, with the best ones about 94% effective, but all vaccines that are approved or submitted for approval are completely (100.00%) effective at preventing death from COVID-19.&lt;br /&gt;
&lt;br /&gt;
The title text references the fact that the two COVID-19 vaccines authorized for use in the United States as of the date of publication (the {{w|Pfizer–BioNTech COVID-19 vaccine|Pfizer-BioNTech one}} and the {{w|Moderna COVID-19 vaccine|Moderna one}}) require [[2422: Vaccine Ordering|two doses of vaccine]] to be fully effective, as do many others in use worldwide (AstraZeneca, Gameleya Institute, Sinovac, etc.). The second dose strengthens the body's immune response to the spike proteins and causes it to &amp;quot;remember&amp;quot;, via antibodies, how to attack those proteins for a long time — hopefully years or even decades. Likewise, the Rebels in the movies destroy two Death Stars, the second one in ''Return of the Jedi''. Incidentally, that second Death Star was destroyed while it was apparently incomplete, much like the Death Star here was destroyed before it could destroy Cueball; however, in the film, the Emperor had deliberately left it with an incomplete outer structure to lure the Rebellion into attacking it, only for the Rebels to find that its superlaser was fully operational.&lt;br /&gt;
&lt;br /&gt;
Vaccination was also explained, xkcd-style, in [[2406: Viral Vector Immunity]]. &lt;br /&gt;
&lt;br /&gt;
References to the ''{{w|Star Wars}}'' franchise are a [[:Category:Star Wars|recurring theme]] on xkcd.&lt;br /&gt;

==Transcript==&lt;br /&gt;
:[Cueball seated in a doctor's office getting a dose of a COVID-19 vaccine. Both he and the doctor are wearing masks; the doctor is also wearing a scrub cap.]&lt;br /&gt;
:Doctor: The vaccine contains mRNA instructions for making the virus spike protein.&lt;br /&gt;
:Cueball: Weird, so the vaccine is just blueprints?&lt;br /&gt;
:Doctor: Yup! Your body reads the mRNA, makes the proteins, and then has an immune reaction to them.&lt;br /&gt;
:Cueball: Why would my body attack something it made itself?&lt;br /&gt;
:Doctor: Well...&lt;br /&gt;
&lt;br /&gt;
:[Princess Leia and General Dodonna in frame.]&lt;br /&gt;

&lt;br /&gt;
:[A view from inside the Death Star again with Cueball at the control panel and the planet in the background windows; various projectiles and explosions can be seen through the window.]&lt;br /&gt;
:Cueball: Can everybody please just chill? We don't even have the laser thing wired up. We—&lt;br /&gt;
:'''''BOOM'''''&lt;br /&gt;
:''Hey!!'' I ''said'', we...&lt;br /&gt;
&lt;br /&gt;
:[Ponytail enters from the left, and points to her left. Princess Leia points at her.]&lt;br /&gt;
:Ponytail: We can't get through! We're running out of proton torpedoes!&lt;br /&gt;
:Leia: Send every crew to build more torpedoes!&lt;br /&gt;
:Ponytail: There aren't enough ships to—&lt;br /&gt;
:Leia: ''Build more ships!!''&lt;br /&gt;
&lt;br /&gt;

:Ponytail: That thing is just sitting there. Are you sure we—&lt;br /&gt;
:Leia: ''Keep building ships! Build ships forever! '''Destroy the orb!'''''&lt;br /&gt;
&lt;br /&gt;
:[A view of the Death Star in space and the curvature of the planet off to the side. An enormous torrent of (barely visible) ships is seen streaming from the planet's surface to the Death Star. The damage to the Death Star is slightly worse.]&lt;br /&gt;

:[Ponytail and Cueball in frame.]&lt;br /&gt;
:Ponytail: Here, take these blueprints to your construction crew.&lt;br /&gt;
:Cueball: Affirmative. What is it?&lt;br /&gt;
:Ponytail: No idea. Something the Princess wants.&lt;br /&gt;
:Cueball: Copy that.&lt;br /&gt;
&lt;br /&gt;
:Panel heading: Soon...&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

		<summary type="html">&lt;p&gt;MisterBadIdea: Are we seriously nitpicking the logic of a comic strip rewriting the Tower of Babel?&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 2421&lt;br /&gt;
| date      = February 5, 2021&lt;br /&gt;
| title     = Tower of Babel&lt;br /&gt;
| image     = tower_of_babel.png&lt;br /&gt;
| titletext = Soon, linguists will be wandering around everywhere, saying things like &amp;quot;colorless green ideas sleep furiously&amp;quot; and &amp;quot;more people have been to Russia than I have,&amp;quot; and speech will become unintelligible.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a COLORLESS GREEN IDEA. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
The story of the {{w|Tower of Babel}} is the Biblical explanation for the existence of different languages in the world. In the story, humans endeavor to build a tower reaching heaven. Their arrogance angers God and prompts him to sabotage the project. He does this by &amp;quot;confounding their speech&amp;quot; (commonly interpreted as giving everyone their own language), inhibiting their ability to work together.&lt;br /&gt;
&lt;br /&gt;
In this retelling, however, the tower is actually finished. God is happy to receive the human visitors, and offers them a reward.&lt;br /&gt;
&lt;br /&gt;
The party that ascends to the top of the tower consists of [[Cueball]], [[Megan]] and a curly haired woman, who may be the linguist {{w|Gretchen McCulloch}} as she was depicted in [[2381: The True Name of the Bear]]. &lt;br /&gt;
&lt;br /&gt;
When the curly haired woman expresses her love of words, God offers to create a panoply of languages. Megan immediately sees the problems with this, but the word-loving woman is enthusiastic. Instead of a punishment by God, linguistic diversity is presented as a well-intended challenge. Megan then states &amp;quot;We should not have brought a {{w|linguist}}.&amp;quot; This is a paradox, since before this day there where only one language, and thus no true linguists. Of course the curly haired woman may have studied their own current language, which would technically make her a [https://www.vocabulary.com/dictionary/grammarian grammarian]. But with only one language this could be said to count as a linguist.&lt;br /&gt;
&lt;br /&gt;
{{w|Phonology}}, a part of linguistics, is the study of the sound system used in a language or dialect, or of the systems that languages use to organize sounds. {{w|b:Conlang/Advanced/Grammar/Alignment|Morphosyntactic alignment}} is the grammatical relationship between the noun arguments to a verb &amp;amp;mdash; for example, between the two arguments (in English, the subject and object) of transitive verbs like ''the dog chased the cat'', and the single argument of intransitive verbs like ''the cat ran away''.&lt;br /&gt;
&lt;br /&gt;
The title text expands the joke by suggesting that the miscommunication caused by the Tower of Babel is not due to language barriers, but instead because of intentionally meaningless sentences created by linguists to illustrate points about grammar, and identifies two famous examples of such . &amp;quot;{{w|Colorless green ideas sleep furiously}}&amp;quot;, coined by linguist {{w|Noam Chomsky}} in 1957, is an example of a sentence that is structurally correct but contains paradoxes and meaningless comparisons: something cannot be both colorless AND green (see {{w|Invisible Pink Unicorn}}), ideas do not sleep, and sleeping is not generally done furiously. That said, the sentence &amp;quot;colorless green ideas sleep furiously&amp;quot; is so well known in linguistics that a competition to make the sentence meaningful was held in 1985 and {{w|Colorless_green_ideas_sleep_furiously#Attempts_at_meaningful_interpretations|attracted a number of entrants}}.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;More people have been to Russia than I have&amp;quot; is a well-known example of {{w|comparative illusion}}. It sounds like it means something but, upon actual analysis, does not, although it could be interpreted as there being more people to visit Russia than the speaker owns, or has in their household.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[The Tower of Babel is shown. It has a broad two sectioned base and above that extends straight up out of the top of the frame, with 10 identical segments. This is seen from afar, so the three people standing at the base of the tower is very small. But Cueball and Megan can be easily identified. They are standing on either side of a woman with big curly hair (which is first clear in the next panel). The text spoken is written over the tower in white sections that hides the tower. But the tower can be seen above, between and below these two text segments:] &lt;br /&gt;
:Cueball: The Tower of Babel is complete!&lt;br /&gt;
:Megan: Let's go meet God!&lt;br /&gt;
&lt;br /&gt;
:[Cueball, the curly haired woman and Megan are now standing at the top of the Tower of Babel. The top is made of bricks, but the part of the last segment before the top looks like those shown in the first panel. God is represented by an off-panel voice coming from a star burst at the top of the panel. The three people look up in that direction.]&lt;br /&gt;
:Cueball: Hi God!&lt;br /&gt;
:God (off-panel): Wow, nice tower!&lt;br /&gt;
:God (off-panel): You did a great job! I'm so proud!&lt;br /&gt;
:Megan: Thanks!&lt;br /&gt;
&lt;br /&gt;
:[Same settings but Megan has turned towards the curly haired woman holding an arm out towards her. The woman has taken one hand to her chin.]&lt;br /&gt;
:God (off-panel): I'm going to give you a reward.&lt;br /&gt;
:God (off-panel): What do you like about the world?&lt;br /&gt;
:Curly haired woman: Hmm. Words are really cool.&lt;br /&gt;
:Megan:  No, wait-&lt;br /&gt;
&lt;br /&gt;
:[Same settings, in a broader panel. The curly haired woman lifts her hands up curled into fists. Her yell comes from a starburst over her head, to indicate the difference to normal speech. Megan has taken her arm down.]&lt;br /&gt;
:God (off-panel): Great! I'm going to give you lots of languages to study, each with its own phonology, word ordering, morphosyntactic alignment...&lt;br /&gt;
:Curly haired woman: '''''YESSSSSS!'''''&lt;br /&gt;
:Megan:  We should '''''not''''' have brought a linguist.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
In [[2381: The True Name of the Bear]], sentences spoken by Gretchen McCulloch do not have periods at their ends, a fact which she mentioned on Twitter. However, in this comic, she uses periods, so her previous periodlessness might be a coincidence and not a trait of her character on xkcd.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1060&lt;br /&gt;
| date      = May 25, 2012&lt;br /&gt;
| title     = Crowdsourcing&lt;br /&gt;
| image     = crowdsourcing.png&lt;br /&gt;
| titletext = We don't sell products; we sell the marketplace. And by 'sell the marketplace' we mean 'play shooters, sometimes for upwards of 20 hours straight.'&lt;br /&gt;
}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Crowdsourcing}} is the practice of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, rather than from traditional employees or suppliers. In the new Internet economy, it is not uncommon for companies to rely on crowdsourced designs or ideas, to contract the marketing to another firm, or to interact with customers through social networks established by other companies. &lt;br /&gt;
&lt;br /&gt;
[[Cueball]], however, is describing a business strategy which manages to do all three by &amp;quot;crowdsourcing&amp;quot; the process of getting a company and a prospective employee together. Cueball describes it as helping people with ideas find funding, similar to Kickstarter or Indiegogo, but rather than setting up a system to facilitate the process, he plans to use already-existing social networks (such as Facebook and Twitter).  Effectively, by relying on outside support for all steps of the business plan, his company does nothing; however, because the parts of his strategy are all feasible separately, and because he describes them with a barrage of trendy buzzwords, his audience is impressed and fails to notice the company's essential pointlessness.&lt;br /&gt;
&lt;br /&gt;
In the title text Cueball claims that &amp;quot;we don't sell a product, we sell the marketplace,&amp;quot; a phrase that typically describes a company whose business model is to facilitate the business of other companies, and would be a plausible reason for a company to not make products. However, this is revealed to be yet more empty buzzwords when Cueball clarifies that they don't actually do any work and instead play video games (&amp;quot;shooters&amp;quot; refer to first person shooters, a genre of video game).&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is standing in front of a flowchart on a wall, indicating with a pointer. A man and two women are looking on with interest. One woman holds a briefcase.]&lt;br /&gt;
:Cueball: We crowdsource the design process, allowing those with the best designs to connect—&lt;br /&gt;
:Cueball: via already-in-place social networking infrastructure—&lt;br /&gt;
:Cueball: with interested manufacturers, distributors, and marketers.&lt;br /&gt;
:[Caption below the panel:]&lt;br /&gt;
:Nobody caught on that our business plan didn't involve ''us'' in any way— it was just a description of other people making and selling products.&lt;br /&gt;

==Explanation==&lt;br /&gt;
''{{w|Frankenstein|Frankenstein; or, The Modern Prometheus}}'' is a novel by Mary Shelley published in 1818. In it, Victor Frankenstein is a human who creates a {{w|Frankenstein%27s_monster#Namelessness|monster}} (who is never named).  In popular culture, however, &amp;quot;Frankenstein&amp;quot; is taken to be the name of the monster, not its creator.&lt;br /&gt;
&lt;br /&gt;
While this is an often-corrected &amp;quot;error&amp;quot;, it has been argued that it is not technically incorrect to call the monster &amp;quot;Frankenstein&amp;quot; as well, since he is the &amp;quot;offspring&amp;quot; of his &amp;quot;father&amp;quot;, Victor Frankenstein. Since a child usually takes on the last name of his father, it may be said that the monster's last name actually ''is'' &amp;quot;Frankenstein&amp;quot;. He also refers to himself in the novel as &amp;quot;the Adam of your labors&amp;quot; - a reference to the Biblical Adam, the first of his kind - and some have taken to calling the monster &amp;quot;Adam Frankenstein&amp;quot; to differentiate him from the scientist, Victor Frankenstein.&lt;br /&gt;
&lt;br /&gt;
Others have argued that the monster's namelessness is an important part of his characterization in the story, since it reflects the doctor's complete rejection of his creation. While the monster identifies Victor as his &amp;quot;father&amp;quot; in the novel, Victor does not consider the creature to be his &amp;quot;son&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
[[Randall]] apparently finds this argument tedious and pedantic, so he has created his own work of fiction, in which the monster is named Frankenstein. He rationalizes that it is now correct to call the monster Frankenstein, assuming that his comic strip is as authoritative as the original novel. &amp;quot;{{w|Canon (fiction)|Canonical}}&amp;quot; (rule, standard) means that this comic should be used as the authoritative work on the naming of the monster. &lt;br /&gt;
&lt;br /&gt;
However, xkcd's ''Frankenstein''' would be unlikely to be accepted by anyone as canonical, except for its stated purpose of settling the naming argument. The original version of any story is usually assumed to be the canonical one, and any derivative work would have to have widespread influence and recognition to supplant it in the popular imagination. This is not likely to happen with xkcd's ''Frankenstein,'' as it makes almost no effort to stand on its own; it exists only to be a version of ''Frankenstein'' where the monster is named &amp;quot;Frankenstein.&amp;quot; It emphasizes this point several times, and ends within a single panel, having accomplished its only goal. Almost no readers would find this version entertaining or substantive enough to displace Mary Shelley's original as the definitive version of the story.&lt;br /&gt;
&lt;br /&gt;
The {{w|Public_domain|copyright}} on Mary Shelley's novel has expired long ago, so it is perfectly legal to create works derived from the original story. It should be noted however, that Universal holds the copyright on the common [https://www.plagiarismtoday.com/2011/10/24/how-universal-re-copyrighted-frankensteins-monster/ image of the monster] (green skin, flat top head, scar, bolts on the neck and protruding forehead). To qualify as a {{w|derivative work}} the story needs to be substantially different from the original. The monster believing in {{w|moon landing conspiracy theories}} would probably qualify. Additionally, the original Frankenstein's monster was seen by its creator as hideous and repulsive due to its physical appearance despite the project being a success. Randall makes the same correlation in his version by having Frankenstein claim the moon landings were faked, which produces the same feelings in The Doctor.&lt;br /&gt;
&lt;br /&gt;
Alternatively, the monster being a moon landing denier is meant as a throwaway absurdist non sequitur. As the only point of this story is to make a canonical version of ''Frankenstein'' where &amp;quot;Frankenstein&amp;quot; is the monster's name, it should logically end once it has finished making that point clear. However, Randall throws a curveball by having the monster blurt out an uncomfortable and controversial point of view before the ending, then ending the story abruptly before the monster's statements can be addressed.&lt;br /&gt;
&lt;br /&gt;
It is also possible that Randall is making reference to the fact that the kind of people who become engrossed in the debate that is attempted to be resolved in this comic and would bother to create a piece like this (which incidentally, complicates matters further rather than simplifying it, similar to the effect of  many pieces of evidence in internet discussions) could be compared to the kind of people who deny the Moon Landings in obscure forums. He is drawing attention to how inane and uneccesary the comic is.&lt;br /&gt;
&lt;br /&gt;
The title text raises the question of what the monster's creator is named in this version, since the name &amp;quot;Frankenstein&amp;quot; is instead given to the monster. The canonical answer is that the creator is simply &amp;quot;The Doctor&amp;quot;, like the title character of the series {{w|Doctor_Who|&amp;quot;Doctor Who&amp;quot;}}. This might be a reference to similar pedantic nitpicking that occurs when that character is incorrectly referred to as &amp;quot;Doctor Who&amp;quot; rather than &amp;quot;The Doctor&amp;quot; which is in turn referenced in comic [[1221: Nomenclature]]. As it happens, people who make that mistake can also claim canonical support, in that some early episodes of the series list the character's name as &amp;quot;Doctor Who&amp;quot; in the credits.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
[[Cueball]] is talking to [[Ponytail]] about the trophy he won for winning the “Motivated Reasoning Olympics” (hence the title). Ponytail rightly points out that the trophy says he only got second place. Cueball then displays the &amp;quot;{{w|motivated reasoning}}&amp;quot; skills that won him the trophy, by claiming that the athlete who beat him cheated in an earlier round and that the judges were “certain” to disqualify him after reviewing. Here, the cognitive dissonance that should result from believing that he won first place but having a trophy that says second place is reduced by Cueball's motivated reasoning. He has developed a narrative that explains away the inconsistent fact of the label on the trophy, and thus, convinces himself that there couldn't have been any shortcoming in his own performance. These are all characteristics of motivated reasoning.&lt;br /&gt;
The title text is a continuation, where Cueball suggests the judges are biased in favor of the original winner, whom they approve of. He further states that this is evidence of corruption and is the reason why his league split off from the official state-sponsored league just prior to the Motivated Reasoning Olympics. Of course, motivated reasoning is an emotion-biased decision-making phenomenon, by definition, so he really should expect the judging to be biased.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BAT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
Cueball echoes a statement made by anti-vaccine activists about &amp;quot;Big Pharma&amp;quot; (the powerful and profit-driven companies who develop pharmaceutical drugs such as vaccines). Anti-vaccine protesters believe that vaccines contain harmful toxins that cause ill effects on the human body, and that the corporations that make them are not to be trusted because they are exploiting a captive public for profit while disregarding public health. The joke is that Cueball is revealed to be not talking about Big Pharma but, instead, bats. &lt;br /&gt;
&lt;br /&gt;
COVID-19 likely originated in bats, so the act of getting the virus would mean having something developed in bats infect his body. Bats, which are unhygeinic disease-carrying animals rather than rational humans, should obviously be trusted less than people to develop something that you should put in your body. &lt;br /&gt;
&lt;br /&gt;
The comic thus serves as a compelling argument against the anti-vaccine movement, which is often criticized for spreading misinformation and increasing rates of disease, especially since the start of the COVID-19 pandemic. This comic comes shortly after the news of the development of several COVID-19 vaccines with high rates of success; there are concerns that herd immunity may be delayed if people refuse to take the vaccine. &lt;br /&gt;
&lt;br /&gt;
The title text refers to getting immunity the old fashioned way, i.e. catching the disease and waiting for your immune system to build up a response. This can be dangerous and sometimes deadly and so should not be taken if it can be avoided. The joke here is that many Anti-vaxers claim that it is more natural to not take a vaccine.&lt;br /&gt;

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

Ponytail, who was eager to see ''{{w|Wonder Woman 1984}}'', the sequel to the acclaimed 2017 ''{{w|Wonder Woman (2017 film)|Wonder Woman}}'' film, decided to block all news media leading up to the film, to avoid {{w|Spoiler (media)|spoilers}}. This is a common practice for people who do not wish to be &amp;quot;spoiled&amp;quot; by reading or hearing any plot points of the film, and want to experience it for the &amp;quot;first time&amp;quot; when watching it. Many early reviewers may inadvertently give away key parts of the film, which may &amp;quot;ruin&amp;quot; the experience for some watchers.&lt;br /&gt;
&lt;br /&gt;
However, there have been many delays for release of the film, in part because of the [[:Category:COVID-19|COVID-19 pandemic]] in the Spring of 2020. The film was originally delayed from November 1, 2019 to June 5, 2020, and then was pushed to August 14, 2020, and October 2, 2020, before it was finally moved to December 25, 2020. The film studio announced a simultaneous release of the film in theaters and also on streaming platform {{w|HBO Max}}.&lt;br /&gt;
&lt;br /&gt;
Absurdly, Ponytail did not turn off her news site blocker and so has not read ''any'' news for the past year, even news unrelated to movies. Because of this, she does not know who became the 2020 Democratic nominee, or who won the 2020 United States presidential election (both {{w|Joe Biden}}). Even more absurdly, she has not noticed others wearing masks, seen any Biden campaign signs, etc.  It also seems that she does not know about the COVID-19 pandemic, as she seems confused as to why her movie is now being shown at a {{w|drive-in theater}}. Drive-in theaters have been seen as a much safer option than regular movie theaters during the pandemic. &lt;br /&gt;
&lt;br /&gt;
Cueball tries to warn her about the ongoing pandemic, but in an effort to avoid spoilers, she refuses to listen to him. Cueball then tells her to wear a mask, but she is still confused. Ponytail says that she will dress up in costume as Wonder Woman, who is traditionally shown wearing a {{w|tiara}}, but not a mask (unlike Batman or many other comic characters, although [[2367: Masks|efficiency of their masks]] still varies wildly in regards to COVID-19 protection).&lt;br /&gt;
&lt;br /&gt;
The title text shows Ponytail’s even more remarkable historical imagination. She believes the move to driv-in theaters to be a &amp;quot;retro promotion,&amp;quot; presumably because drive-ins and the '80s setting of the movie are now both considered to be retro now. However, drive-in theaters are not of the same time period as the movie; according to Wikipedia, drive-in theaters were in fact in decline in the 80s due to the advent of cable TV, VCRs, and home video. Ponytail further demonstrates more misunderstanding of history by mentioning several other things which she wrongly believes are from the '80s. {{w|Britney Spears}} was popular in the late 1990s and early 2000s. {{w|Hustle(dance)|The Hustle}} was a disco dance popular in the mid 1970s.  {{w|Pogs}} under that name peaked in the mid-1990s.  {{w|Elvis}}'s appearance on the ''{{w|Ed Sullivan Show}}''- one of the pivotal moments of American pop culture- occurred on September 9, 1956. Cueball points out this mess of inconsistencies by asking Ponytail when she was born, referring to the idea that she would subconsciously combine all these time periods because she didn't live through them, and only knows about them through pop culture.&lt;br /&gt;
&lt;br /&gt;

| title     = Feathered Dinosaur Venn Diagram&lt;br /&gt;
| image     = feathered_dinosaur_venn_diagram.png&lt;br /&gt;
| titletext = My pet theory is that in real life, the kid at the beginning of Jurassic Park who made fun of the 'six-foot turkey' never got a talking-to from Dr. Grant, and grew up to produce several of the movie's sequels.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Translated plainly, this comic reads &amp;quot;People who don't think feathered dinosaurs sound scary, have never tried to fight an ostrich.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
This comic is a jab at people who dismiss the idea feathered dinosaurs sound scary.  Adding feathers to a reptile can trigger a cognitive dissonance; people today see feathers and think of harmless birds. However, the {{w|Ostrich|ostrich}} (and a few other avian species, which are {{w|Origin of Birds|feathered dinosaurs}}) are in fact deadly.  The diagram points out that anyone who has tried to fight an ostrich would be scared of a dinosaur with feathers, and anyone who thinks a feathered dinosaur doesn't sound scary has never tried to fight one.  The two groups of people are exclusive because the two circles do not overlap. &lt;br /&gt;
&lt;br /&gt;
Ostriches are not typically considered scary or dangerous because its appearance is comical or awkward to most people; they are also herbivorous and not typically aggressive, choosing to use its great speed to outrun predators rather than fight them. In reality, however, ostriches are much larger than a human and will attack when cornered or when their family is threatened; their powerful legs can kick hard enough to kill lions and other predators, and their feet are equipped with large claws which can disembowel a human. Thus, the actual experience of fighting an ostrich would quickly convince any human that survives the experience that ostriches (and by extension other feathered dinosaurs) are, in fact, scary.&lt;br /&gt;
&lt;br /&gt;
The title text refers to &amp;quot;[http://jurassicpark.wikia.com/wiki/Volunteer_Boy Volunteer Boy]&amp;quot;, a kid in the beginning of Jurassic Park who dismisses a raptor fossil as a &amp;quot;six-foot turkey&amp;quot;. Dr. Grant uses a fossil of a raptor talon to imply that a raptor would slice open his belly and eat him while he's still alive. This scares the kid into respecting the raptor.  The title text theorizes that if he didn't get that pep talk, and continued to think of dinosaurs as &amp;quot;six-foot turkeys&amp;quot;, then he would grow up to make some of the contested sequels in the franchise. Raptors play a central role throughout the series of movies, with some even being trained by a raptor handler like dogs.&lt;br /&gt;
&lt;br /&gt;
[[Technically]], the diagram is an {{w|Euler diagram}}, rather than a {{w|Venn diagram}}. A Venn diagram shows all possible combinations of two or more sets, including those with no elements, and so all of the circles must intersect. An Euler diagram only depicts the non-empty combinations, and therefore does not have this constraint. However, this is a technicality, and many people use the words interchangeably.&lt;br /&gt;

Much like most of Beret Guy's interactions with people, Beret Guy is cheerful and upbeat, yet indicates that he has at best a scrambled understanding of how people in this situation normally act. Because of this, the job interview becomes increasingly bizarre, starting with Beret Guy's assertion that the company headquarters is a &amp;quot;real building [he] found&amp;quot;, implying that the building's reality might be in question. In addition, &amp;quot;finding&amp;quot; the building may imply that he does not own or rent it, but simply found it empty and moved in. He says his company makes phone accessories, but then adds, &amp;quot;like apps and stickers,&amp;quot; two wildly different products in terms of both production and profitability. He is strangely vague about both the position (&amp;quot;someone to write on our computers&amp;quot;) and the salary (&amp;quot;a bunch of paychecks&amp;quot;). Then he mentions ghosts, which is either a powerful disincentive from joining the company, yet another sign that Beret Guy is mentally unsound, or both.&lt;br /&gt;
&lt;br /&gt;
The strip finishes with Beret Guy plugging a cord into an electrical outlet clumsily labeled &amp;quot;Soup,&amp;quot; which then, implausibly, actually starts dispensing soup. Most businesses do not function like this.{{Citation needed}} However, this is a typical behaviour of Beret Guy - see a similar example in: [[1395: Power Cord]].&lt;br /&gt;
&lt;br /&gt;
The title text makes reference to the biblical story of {{w|Job (biblical figure)|Job}} (pronounced with a long O to rhyme with globe), who was put through many horrendous ordeals to test his faith in God. This suggests that the interviewee will be taking on not a &amp;quot;job experience&amp;quot; but rather a &amp;quot;Job experience&amp;quot; (i.e. the job will be a horrendous ordeal.&lt;br /&gt;
&lt;br /&gt;
Other job interviews were portrayed in [[125: Marketing Interview]], [[1088: Five Years]], [[1094: Interview]], and [[1545: Strengths and Weaknesses]].&lt;br /&gt;

:[Beret Guy walks in, followed by a...'prospective hire'.]&lt;br /&gt;
:Beret Guy: Welcome to our company! We're headquartered here, in this real building I found!&lt;br /&gt;
&lt;br /&gt;
:[Both people sit down at a table. The 'hire' has a tray with food and a beverage. Beret Guy has a bowl. In the adjacent wall, there is a power outlet with a paper label taped to it marked &amp;quot;Soup&amp;quot;. A small roll of wire sits next to Beret Guy's chair.]&lt;br /&gt;

&lt;br /&gt;
:[Beret Guy unrolls the wire and plugs it into the wall.]&lt;br /&gt;
:'Hire': ...Are you sure this is a company?&lt;br /&gt;
:Beret Guy: I hope so!&lt;br /&gt;

:[Soup (or something one can only hope is soup) streams out of the plugged-in wire into Beret Guy's bowl.]&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BOT that's more of a FRIENDLY BUG. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Usually at a conference or other event involving a speaker addressing a crowd, members of the crowd are given the chance to ask questions. This is intended so that people can perhaps ask the speaker to elaborate on a point they've made, or to ask the speaker's opinion on a topic related to their talk.  &lt;br /&gt;
&lt;br /&gt;
Occasionally, people at such an event will use (or, rather, abuse) the opportunity to ask a question to instead provide their own (unsolicited) opinion or statement. Such statements are often preceded with something along the lines of &amp;quot;I have a question. Well, less of a question and more of a comment.&amp;quot;   This formulation in particular has attracted a lot of criticism, eg. [https://jamesmendezhodes.com/blog/2019/4/30/less-of-a-question-more-of-a-comment], for not adding anything to the discussion and for pulling focus away from the speaker.&lt;br /&gt;
&lt;br /&gt;
In the comic, this idea is taken to an extreme, with [[Beret Guy]] not only transforming the opportunity to ask a question into an opportunity to make a statement, but through successive transformations, turning this into an opportunity to show off a bug he has found. &lt;br /&gt;
&lt;br /&gt;
:'''Question'''  This is what the crowd member is expected to provide, such that the speaker or a panel member could provide a related answer.&lt;br /&gt;
&lt;br /&gt;
:'''Comment'''  This is where the crowd member would just say something they believe, without expecting an answer, giving the speaker or panel members nothing to do.&lt;br /&gt;
&lt;br /&gt;
:'''Utterance'''  This is making a noise, which may or may not be actual words, or if actual words it may not be a complete sentence.&lt;br /&gt;
&lt;br /&gt;
:'''Air Pressure Wave'''  Sounds are literally pressure waves in the air.  So this could be a simple sound, or not a sound at all depending on the severity of the wave.  It might be the person simply blowing.&lt;br /&gt;
&lt;br /&gt;
:'''Friendly Hand Wave'''  Now instead of using his mouth to generate an air pressure wave, he's producing it with his hand, in a manner intended to be interpreted as &amp;quot;friendly&amp;quot;.  Many times hand waves are done in a friendly manner, designed more for the visual appeal than the amount of air pressure waves they generate.&lt;br /&gt;
&lt;br /&gt;
:'''Friendly Bug'''  Now he is no longer doing anything himself, except to point out the fact that he has found a bug or {{w|insect}}, which he {{w|anthropomorphizes}} as being friendly.&lt;br /&gt;
&lt;br /&gt;
:'''Want to meet it?'''  He has decided that he and the friendly bug are actual friends, and ironically comes full circle by finally asking a question, though presumably whether the speaker wants to meet a bug is not related to the topic of the speaker's talk.&lt;br /&gt;
&lt;br /&gt;
The title text refers to successively worse forms of magic spells which would, presumably, have a negative effect upon the listener. A malediction is another word for curse (the prefix &amp;quot;mal&amp;quot; being a Latin root meaning &amp;quot;evil&amp;quot;). &amp;quot;Word of Power&amp;quot; could refer to the dragonish form of magic in ''{{w|The Elder Scrolls V: Skyrim}},'' or the [https://dungeonsdragons.fandom.com/wiki/Power_word early 1st edition Dungeons &amp;amp; Dragons high level spells]. The term &amp;quot;{{w|Magic_in_Harry_Potter#Unforgivable_Curses|Unforgivable Curse}}&amp;quot; refers to a set of three spells from the Harry Potter series, said to be so evil that their use on another person is unforgivable and illegal. The three spells are able to mind control (''Imperius''), torture (''Cruciatus''), and kill (''Avada Kedavra'') their target.&lt;br /&gt;
&lt;br /&gt;
The title text can be interpreted as a reply by [[Hairy]] (the speaker) to Beret Guy, indicating his annoyance at the topic being derailed. It could also be representative of Randall's feelings towards those who abuse the opportunity to ask a question in order to make a statement.  Randall has recently done some book tours and was at {{w|San Diego Comic-Con}} [https://blog.xkcd.com/2019/07/15/san-diego-comic-con/ last month] where he served on various panels, so he probably had personal first-hand experience with these kinds of circuitous non-questions.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Hairy stands on a podium having just addressed a crowd of seated people. Beret Guy stands in the middle of the crowd, addressing Hairy. One of Beret Guy's hands is raised at chest height. The front row consists of Cueball, Ponytail, another Hairy, Megan, Hairbun, Danish and another Cueball.]&lt;br /&gt;
&lt;br /&gt;
:Beret Guy: I have a question.&lt;br /&gt;
:Beret Guy: Well, less of a question and more of a comment.&lt;br /&gt;
:Beret Guy: I guess it's less of a comment and more of an utterance.&lt;br /&gt;
:Beret Guy: Really it's less an utterance more an air pressure wave.&lt;br /&gt;
:Beret Guy: It's less an air pressure wave and more a friendly hand wave.&lt;br /&gt;
:Beret Guy: I guess it's less a friendly wave than it is a friendly bug.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a HAWAIIAN-GREEK HYBRID. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Many academics and aficionados argue that studying old texts in the original language is more valuable than reading translations. The argument is that translations are rarely able to fully capture all of the nuances, linguistic subtleties and intent of the original author, and may even alter the meaning in some way. The drawback to this is that it requires the reader to be sufficiently fluent in whatever language the text is written in, which is frequently an archaic dialect, and so only really useful for studying old texts. Mastering an obsolete language solely to enhance your reading experience is a big commitment, and so has become something of a signifier of a truly dedicated scholar. By the same token, bragging about such signifiers is often taken as a mark of self-involved academic arrogance. Because many of the foundational texts in Western civilizations (the New Testament of the Bible being the most notable) were written in Ancient Greek, commenting that you only read works &amp;quot;in the original Greek&amp;quot; has long been an indicator of high-level literary scholarship. &lt;br /&gt;
&lt;br /&gt;
The joke in this strip is that Cueball has apparently taken the time to learn Greek, so that he can read Wikipedia in that language. However, he is not reading the &amp;quot;original&amp;quot; version of Wikipedia articles, but their equivalent in the [https://el.wikipedia.org/wiki/%CE%A0%CF%8D%CE%BB%CE%B7:%CE%9A%CF%8D%CF%81%CE%B9%CE%B1 modern Greek language edition of Wikipedia]. Wikipedia has editions in nearly every existing language; each article links to equivalent articles in other languages, but they are not usually translations of each other, having been written separately by speakers of the different languages. The dedication to appearing to be a committed scholar is contrasted with the ignorance of not understanding that Greek is not the original language of every text. &lt;br /&gt;
&lt;br /&gt;
The title text is an etymology joke, since &amp;quot;Wikipedia&amp;quot; was coined from two parts, &amp;quot;[https://en.wiktionary.org/wiki/wiki#English wiki]&amp;quot;, from Hawaiian, and &amp;quot;[https://en.wiktionary.org/wiki/-pedia pedia]&amp;quot;, from Greek. However, words having roots in different languages is common and does not signify any link between the separate languages; for example, while the word &amp;quot;Wikipedia&amp;quot; does have etymological roots in Hawaiian and Greek, there is no hybrid of the two languages which articles could be written in.&lt;br /&gt;
&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Hunter S Thompson was high while writing it. Do NOT delete this tag too soon.}}&lt;br /&gt;
[[Megan]] is telling [[Cueball]] about some of her literary opinions: She believes that {{w|William S. Burroughs}}, {{w|Hunter S. Thompson}}, {{w|Chuck Palahniuk}}, and {{w|David Foster Wallace}} are different names for the same person. Many authors write under {{w|pen name|pen names}} for some of their works, or even several different pen names.  Sometimes people come to believe that different people are actually a same person, which is known as the {{w|Fregoli delusion}}; the person is usually believed to change appearance. &lt;br /&gt;
&lt;br /&gt;
She then says that ''{{w|Fear and Loathing in Las Vegas}}'' (by Thompson) and ''{{w|Fight Club (novel)|Fight Club}}'' (by {{w|Chuck Palahniuk}}) are the same book with different covers, probably because the title and promotional images for both hint at fighting taking place in a big city (i.e., she is literally {{w|Don't judge a book by its cover|judging the books by their covers}}), when in reality the books are vastly different.  Books sometimes have [https://www.rifflebooks.com/list/170553 different covers and titles in different regions].  &lt;br /&gt;
&lt;br /&gt;
Cueball realizes anyone who has so much as looked at the first page would know this to be false, and so offers Megan the chance to check. She refuses and just moves on to the next opinion she wants to share.&lt;br /&gt;
&lt;br /&gt;
Cueball realizes all her &amp;quot;literary opinions&amp;quot; are probably about books she has not read, and tries to interrupt her, humorously proposing she should start a {{w|Book discussion club|book club}} to discuss them. This may be to congregate all people who criticize books without reading them, or in hopes that it will be attended by people who have read the book and can prove to Megan her opinions are baseless.&lt;br /&gt;
&lt;br /&gt;
Megan finishes telling him her opinion anyway, which is that {{w|E.B. White}} and {{w|T.H. White}} are the same person. This is apparently an opinion that Cueball can agree with, as he tells her that he believes it. This is likely a joke that the two names are hard to distinguish due to the having the same last name with only initials instead of a first name. In reality, the books they authored are very different, with E.B. White writing children's books (''{{w|Charlotte's Web}}'', ''{{w|Stuart Little}}'', etc.) and T.H. White writing adult books about King Arthur (''{{w|The Sword in the Stone}}'' and its sequels), although his works ''were'' adapted into a {{w|The Sword in the Stone (1963 film)|Disney movie}} so they could, to some degree, be considered children's books.&lt;br /&gt;
&lt;br /&gt;
The title text continues with this, with Megan saying that she can distinguish between {{w|John Steinbeck}} and {{w|John Updike}}, or between {{w|Gore Vidal}} and {{w|Vidal Sassoon}}, but she can't do so simultaneously. Again this is likely due to the similarities in their names. However, John Steinbeck and John Updike are also easy to confuse because they are both giants of 20th century American literature, whereas Gore Vidal has almost nothing in common with Vidal Sassoon (see chart below).&lt;br /&gt;
&lt;br /&gt;
Additionally, the mention of simultaneity could be a nod to the {{w|Heisenberg uncertainty principle}}, which states that there is a trade-off in precision when simultaneously measuring position and momentum.&lt;br /&gt;

==Explanation==&lt;br /&gt;
&lt;br /&gt;
This comic discusses reviews of ''{{w|The Emoji Movie}}'' (previously covered in [[1857: Emoji Movie]]) between the cynical, Internet-equipped point of view of Megan and Cueball's language-enthusiasm. They ultimately agree the movie is bad.&lt;br /&gt;
&lt;br /&gt;
''The Emoji Movie'' was released to theaters in late July 2017 and received nearly universally-negative reviews. It is particularly notable for having a rating below 10% on the review aggregator site {{w|Rotten Tomatoes}}. Many critics of movie point to superficial problems like the subject matter and the product placement. Here, that train of thought is articulated a bit more, and ultimately it's argued that the real reason the film is bad is because the creators cashed in on a trend without doing any research into it.&lt;br /&gt;
&lt;br /&gt;
When [[Megan]] first mentions the movie's negative reviews, [[Cueball]] initially accuses the audience of being overly judgmental of the subject matter. He further expresses his fondness for {{w|emoji}} as an interesting and quirky part of language.&lt;br /&gt;
&lt;br /&gt;
Cueball offers an early defense of ''The Emoji Movie'' by comparing it to ''{{w|The Lego Movie}}'', which – despite effectively being an entire movie of {{w|product placement}} for {{w|Lego}} – received generally positive reviews.&lt;br /&gt;
&lt;br /&gt;
They start talking about a &amp;quot;Meh&amp;quot; emoji, who is the main character of the movie. The idea of &amp;quot;{{w|meh}}&amp;quot; as an emoji is actually ambiguous, as various emoji can be used to describe being unimpressed or neutral towards something. As given in examples from comic those are 😒 ({{w|Emoticons (Unicode block)|U+1F612}} Unamused face), 😐 (U+1F610 Neutral face) or 😕 (U+1F615 Confused face). The selection of a less identifiable emoji for the leading role also contrasts with the fact that the movie also features more iconic emojis.&lt;br /&gt;
&lt;br /&gt;
Megan mentions that one of the attempted jokes in the film is a room full of emojis that are unpopular. Bizarrely, the eggplant emoji (🍆, U+1F346 Aubergine) is featured among them. This is a clear sign that the creative team in charge of this movie had limited first-hand experience with SMS messaging; as any frequent user of emoji will tell you, the 🍆 is frequently used as a sly stand-in for a penis, due to its similar shape. [http://knowyourmeme.com/memes/eggplant-emoji-%F0%9F%8D%86] Cueball's reaction is to ask whether the creators of this film intentionally got this wrong (perhaps as a joke, or active denial of the emoji's common usage because it wouldn't be appropriate for a kid's movie).&lt;br /&gt;
&lt;br /&gt;
The line from the Wikipedia plot summary was a {{w|Special:Permalink/793251548|direct quote from Wikipedia}}. The sentence was introduced to the article by editor {{w|User:Voicebox64|Voicebox64}} on {{w|Special:Diff/792689187|July 28, 2017}}, and the exact phrasing quoted in the comic came from editor {{w|User:SubZeroSilver|SubZeroSilver}} on {{w|Special:Diff/793088884|July 30}}. Cueball's response to hearing this line, stating that &amp;quot;it's possible this movie is bad&amp;quot;, is likely due to the fact that piracy is the act of obtaining media illegally, generally without paying for it over the internet. This means that there is a very low chance of there being a 'piracy app', as an app such as this would not be allowed on any online app store.  (A few piracy-focused apps do exist, like {{w|Popcorn Time}}, but they are not available in app stores for obvious reasons.)  This plot point is made more ludicrous as there is no hacker emoji, or even an emoji that could be mistaken for one. Jailbreak's design in the movie also does not bear a resemblance to any existing emoji. (This lack of any existent hacker emoji, however, is addressed in the movie; when pressed on the topic, Jailbreak is revealed to be the princess emoji in disguise.) Furthermore, the blatant product placement of the protagonists' desires to use Dropbox, the proprietary software of a for-profit company, is the final nail in the movie's coffin in Cueball's opinion. The fact that Jailbreak's plans to live 'in the cloud' superficially match with Dropbox's cloud storage service does not salvage the concept.&lt;br /&gt;
&lt;br /&gt;
The title text is an argument against the common prediction that emojis would lead to less nuanced communication, and as evidence it cites the thinking face emoji (🤔) and upside-down smiley (🙃), both of which are used in ways that have developed difficult-to-define nuances and meanings. In the first case, the thinking-face emoji is often used sarcastically -- for example, feigning confusion when presented with contradictory/hypocritical statements from the same source. The upside-down smiley also has specific usage, indicating a tone of silliness or even insanity, and is also often used sarcastically, such as when reacting to bad news.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by Dead people trapped in an Escape room. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
Randall is trying to create the &amp;quot;greatest {{w|escape room}} game of all time&amp;quot;. &lt;br /&gt;
&lt;br /&gt;
The top six panels show a stylized version of various options where people try to get in or out of rooms:&lt;br /&gt;
&lt;br /&gt;
* Escape rooms: An escape room is a type of puzzle/adventure game where people are locked in a room, or set of rooms, (discounting emergency exits) and have a certain amount of time to solve the puzzles and leave.&lt;br /&gt;
* {{w|Heist film|Heist movies}}: In heist movies, the thieves are trying to get in to a room, usually to steal what's inside.&lt;br /&gt;
* ''{{w|Home Alone}}'' (1990): This refers to the first movie in a franchise, where the home that the burglars tried to rob was protected by someone from the inside, Kevin McCallister (also mentioned in the title text).&lt;br /&gt;
* The Battle of Winterfell: This refers to the {{w|The Long Night (Game of Thrones episode)|3rd episode}} of the 8th season of ''{{w|Game of Thrones}}'', aired five days before the publication of this comc. Here the dead tried to enter the {{w|keep}} (the middle room in the picture), but the keep already contained a crypt, with some dead inside, who could also try to leave that internal &amp;quot;room&amp;quot; as well.&lt;br /&gt;
* ''{{w|Inception}}'' (2010): In the movie ''Inception'' the protagonists could enter the dream world of others, and while in those dreams they could entering the dream of someone inside the dream. ''Inception'' can be categorized as a &amp;quot;heist&amp;quot; movie, as the main characters are thieves who steal information from their victim's subconscious.&lt;br /&gt;
* ''{{w|Divine Comedy|The Divine Comedy}}'' (1320): This refers to {{w|Dante Alighieri|Dante}}'s work - in particular its first part ''{{w|Inferno (Dante)|Inferno}}'', which depicts Hell as nine concentric circles. {{w|Purgatorio|Purgatory}} and {{w|Paradiso (Dante)|paradise}} are similarly concentric, but they are not likely to need to be escaped.&lt;br /&gt;
&lt;br /&gt;
At the end, Randall proposes a combination of all of these things, and also combining it with others, to form the &amp;quot;greatest escape room game of all time&amp;quot;:&lt;br /&gt;
&lt;br /&gt;
* ''{{w|The Truman Show|Truman Show}}'': The protagonist of this movie was living in a constructed reality show, although he did not know it.&lt;br /&gt;
* Kevin McCallister's house/subconscious: Refers to the 8-year-old boy who is the main character in the movie ''Home Alone'' who protects his home from the burglars.&lt;br /&gt;
* {{w|Styx}}: A river in Greek mythology that forms the boundary between Earth and Underworld (&amp;quot;Hades&amp;quot;). It is necessary to cross the river Styx to enter or exit the Underworld.  Hell is often likened to the underworld.&lt;br /&gt;
&lt;br /&gt;
The title text refers to [https://www.thedailybeast.com/home-alone-is-so-much-better-if-kevin-mccallister-is-dead this article], which claims that Kevin McCallister is dead, and is actually a ghost.&lt;br /&gt;

| titletext = In a tribute to classical Latin, I started pronouncing it 'per-kent.' Eventually my friends had to resort to spritzing me with a water bottle like a cat to train me out of it.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a Classicist and a Mathematician. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
On March 29, 2019, The AP Stylebook changed a long-standing rule that forbade press writers from using the percent sign (&amp;quot;%&amp;quot;) when writing percentages. This had long been a controversial rule, leading to much debate over the preferable way to write percentages, before the Associated Press finally conceded the point. &lt;br /&gt;
&lt;br /&gt;
The comic lists the best to worst ways in which you can write out phrases that are phonetically the same as &amp;quot;65%&amp;quot;.  They go from the common &amp;quot;65%&amp;quot; and &amp;quot;65 percent&amp;quot; to &amp;quot;65 per cent,&amp;quot; which is not common in Randall's area and time, to the odd &amp;quot;sixty-five%&amp;quot; and &amp;quot;65 per¢&amp;quot; (using the cent currency symbol) which are not really used and look archaic. The middle option, &amp;quot;65 per cent&amp;quot;, was common in older literature, along with &amp;quot;65 per cent.&amp;quot;, using &amp;quot;cent.&amp;quot; as an abbreviation for &amp;quot;centum&amp;quot;, which is Latin for &amp;quot;hundred&amp;quot;.  (&amp;quot;per&amp;quot; is Latin for &amp;quot;through&amp;quot;).  The entire string would translate to &amp;quot;65 for every hundred.&amp;quot; &amp;quot;Per cent&amp;quot; is more widely used in British English than in American English today.&lt;br /&gt;
&lt;br /&gt;
Other abbreviations not mentioned in the comic include &amp;quot;pct.&amp;quot;, &amp;quot;pct&amp;quot; or &amp;quot;pc&amp;quot;.[https://en.wikipedia.org/wiki/Percentage]&lt;br /&gt;
&lt;br /&gt;
The title text references the ambiguity of [https://en.wikipedia.org/wiki/Hard_and_soft_C hard and soft C] in English. In Classical Latin, &amp;quot;C&amp;quot; was always pronounced like &amp;quot;K&amp;quot;. However, in English, most &amp;quot;C&amp;quot;s before E and I (including &amp;quot;percent&amp;quot;) are &amp;quot;soft&amp;quot;, and pronounced like &amp;quot;S&amp;quot;. Some students of Latin may adopt the Latin pronunciation of English words derived from Latin. Such people may pronounce &amp;quot;celtic&amp;quot; like &amp;quot;keltic&amp;quot;, &amp;quot;caeser&amp;quot; like &amp;quot;kaiser&amp;quot;, or &amp;quot;cent&amp;quot; like &amp;quot;kent&amp;quot; (although some might be saying the more accurate phrase pronunciation &amp;quot;pare kentum&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
In this case, Randall's friends found him so annoying they trained him out of it like a cat by spraying him with water every time he pronounced the word &amp;quot;per-kent.&amp;quot; Training people this way was previously a punchline in [[220: Philosophy]].&lt;br /&gt;

| titletext = My pet theory is that in real life, the kid at the beginning of Jurassic Park who made fun of the 'six-foot turkey' never got a talking-to from Dr. Grant, and grew up to produce several of the movie's sequels.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Translated plainly, this comic reads &amp;quot;People who don't think feathered dinosaurs sound scary, have never tried to fight an ostrich.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
This comic is a jab at people who dismiss the idea feathered dinosaurs sound scary.  Adding feathers to a reptile can trigger a cognitive dissonance; people today see feathers and think of harmless birds. However, the {{w|Ostrich|ostrich}} (and a few other avian species, which are {{w|Origin of Birds|feathered dinosaurs}}) are in fact deadly.  The diagram points out that anyone who has tried to fight an ostrich would be scared of a dinosaur with feathers, and anyone who thinks a feathered dinosaur doesn't sound scary has never tried to fight one.  The two groups of people are exclusive because the two circles do not overlap. &lt;br /&gt;
&lt;br /&gt;
Ostriches are not typically considered scary or dangerous because its appearance is comical or awkward to most people; they also are not typically aggressive, choosing to use its great speed to outrun predators rather than fight them. In reality, however, ostriches are much larger than a human and will attack when cornered or when their family is threatened; their powerful legs can kick hard enough to kill lions and other predators, and their feet are equipped with large claws which can disembowel a human. Thus, the actual experience of fighting an ostrich would quickly convince any human that ostriches (and by extension feathered dinosaurs) are, in fact, scary.&lt;br /&gt;
&lt;br /&gt;
The title text refers to &amp;quot;[http://jurassicpark.wikia.com/wiki/Volunteer_Boy Volunteer Boy]&amp;quot;, a kid in the beginning of Jurassic Park who dismisses a raptor fossil as a &amp;quot;six-foot turkey&amp;quot;. Dr. Grant uses a fossil of a raptor talon to imply that a raptor would slice open his belly and eat him while he's still alive. This scares the kid into respecting the raptor.  The title text theorizes that if he didn't get that pep talk, and continued to think of dinosaurs as &amp;quot;six-foot turkeys&amp;quot;, then he would grow up to make some of the contested sequels in the franchise. Raptors play a central role throughout the series of movies, with some even being trained by a raptor handler like dogs.&lt;br /&gt;
&lt;br /&gt;
[[Technically]], the diagram is an {{w|Euler diagram}}, rather than a {{w|Venn diagram}}. A Venn diagram shows all possible combinations of two sets, including those with no elements, and as such all of the circles must intersect. An Euler diagram only depicts the non-empty combinations, and therefore does not have this constraint. However, this is a technicality, and many people use the words interchangeably.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Translated plainly, this comic reads &amp;quot;People who don't think feathered dinosaurs sound scary, have never tried to fight an ostrich.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
This comic is a jab at people who dismiss the idea feathered dinosaurs sound scary.  Adding feathers to a reptile can trigger a cognitive dissonance; people today see feathers and think of harmless birds. However, the {{w|Ostrich|ostrich}} (and a few other avian species, which are {{w|Origin of Birds|feathered dinosaurs}}) are in fact deadly.  The diagram points out that anyone who has tried to fight an ostrich would be scared of a dinosaur with feathers, and anyone who thinks a feathered dinosaur doesn't sound scary has never tried to fight one.  The two groups of people are exclusive because the two circles do not overlap. &lt;br /&gt;
&lt;br /&gt;
The ostrich appears comical and awkward to most people, and is not considered by many to be scary or dangerous because its first defense is its great speed, not any physical attacks. In reality, however, ostriches will attack when cornered, and their kicks are powerful enough to kill lions and other predators. Those kicks are made more dangerous by the ostrich's large claws, which can disembowel a human. Thus, the actual experience of fighting an ostrich would quickly convince any human that ostriches are, in fact, scary.&lt;br /&gt;
&lt;br /&gt;
The title text refers to &amp;quot;[http://jurassicpark.wikia.com/wiki/Volunteer_Boy Volunteer Boy]&amp;quot;, a kid in the beginning of Jurassic Park who dismisses a raptor fossil as a &amp;quot;six-foot turkey&amp;quot;.

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] (or [[Randall]]) is musing about the possibility of being a woman, to the confusion of the man next to him. His uninsightful rambling would likely be unimpressive in most situations, but not odd enough on its own to prompt the second man's baffled reaction. However, the true reason for his confusion is revealed by the caption: Cueball is administering the {{w|Oath of office of the President of the United States|presidential oath}}. The oath is administered by reciting it to prompt a new president to repeat them back to him. However, he botches it completely by forgetting about his task completely and wondering aloud about an unrelated topic. Thus, the president's confused question at the beginning is not him asking for clarification; he is repeating what he at first believed to be the oath of office, but got flustered when he realized Cueball had deviated from the script. When Cueball then continues by replying that &amp;quot;the menstruation thing is freaky,&amp;quot; the president is completely derailed.&lt;br /&gt;
&lt;br /&gt;
On January 20, 2009 the inauguration of {{w|Barack Obama}}'s first office took place. Chief Justice {{w|John Roberts}}, who was administering the oath, {{w|Oath of office of the President of the United States#Oath mishaps|made a mistake}} while reciting the words. This comic references the event and wildly exaggerates the deviation from the oath for comedic purposes.&lt;br /&gt;
&lt;br /&gt;
In truth, the error was rather small: the oath as prescribed in the constitution is:&lt;br /&gt;
:I do solemnly swear that I will faithfully execute the office of President of the United States and will to the best of my ability preserve, protect, and defend the Constitution of the United States.&lt;br /&gt;
&lt;br /&gt;
Due to a missed memo on the pauses planned by the Chief Justice, Obama inadvertently interrupted Roberts during the first phrase - Roberts begins by saying I, Barack Obama, do solemnly swear, and Obama repeats his name while Roberts finishes that sentence. This disturbs Roberts who was not using notes, and he rendered the next phrase as &amp;quot;that I will execute the office of president to the United States faithfully,&amp;quot; misplacing the word ''faithfully'' and saying ''president to'' instead of ''president of''. Obama repeated, &amp;quot;that I will execute&amp;quot;, then paused. Roberts attempted to correct the wording, but stumbled: &amp;quot;the off— faithfully the pres— the office of President of the United States.&amp;quot; Obama then repeated Roberts' initial incorrect wording.&lt;br /&gt;
&lt;br /&gt;
However small the error was it was big enough that Obama did {{w|Oath of office of the President of the United States#Retaking the oath of office|retake the oath of office}} the day after the mistake was made.&lt;br /&gt;
&lt;br /&gt;
The title text continues the wondering about being a woman going on from the {{w|menstruation}} to the {{w|ovaries}}. To make sure it is clearly the oath mistake that is referenced the sentence ends with '... faithfully.' Thus mimicking the real mistake of placing this word last.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is administering the presidential oath.]&lt;br /&gt;
:Cueball: You know, it might be cool to be a woman.&lt;br /&gt;
:President: It... might be cool to be a woman?&lt;br /&gt;
:Cueball: Yeah, but the menstruation thing is freaky.&lt;br /&gt;
:President: Yeah, but... the... um. What?&lt;br /&gt;
:[Caption below the frame:]&lt;br /&gt;
:Turns out I'm even worse at administering the presidential oath than John Roberts.&lt;br /&gt;

}}&lt;br /&gt;
__TOC__&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Map projection}}, or how to represent the spherical Earth surface onto a flat support (paper, screen...) to have a usable map, is a long-time issue with very practical aspects (navigation, geographical shapes and masses visualization, etc.) as well as very scientific/mathematical ones, involving geometry or even abstract algebra among other things. There is no universal solution to this problem: Any 2D map projection will always distort in a way the spherical reality. Many projections have been proposed in various contexts, each intending to minimize distortions for specific uses (for nautical navigation, for aerial navigation, for landmass size comparisons, etc.) but having drawbacks from other points of view. Some of them are more frequently used than others in mass media and therefore more well-known than others, some are purely historical and now deprecated, some are very obscure, etc.&lt;br /&gt;
&lt;br /&gt;
[[Randall]] suggests here the idea that someone's &amp;quot;favorite&amp;quot; map projection can reveal aspects of their personality, then goes through a series of them to show what they can mean. &lt;br /&gt;
&lt;br /&gt;
He may actually believe that all map projections are in a way bad. This could be inferred from the fact that he much later began  publishing a series of [[:Category:Bad Map Projections|Bad Map Projections]], starting with [[1784: Bad Map Projection: Liquid Resize]], which was Bad Map Projection #107 on his list, and was followed up by #79: [[1799: Bad Map Projection: Time Zones]]. The projections below could be #1-#12 on that list, although the last one, where Randall hates those that love it, might be somewhat further down the list.&lt;br /&gt;
&lt;br /&gt;
===Mercator===&lt;br /&gt;
[[File:MercatorProjection.jpg|frame|The Mercator projection]]&lt;br /&gt;
The {{w|Mercator projection}} was introduced by Flemish cartographer Gerardus Mercator in 1569. The main purpose of this map is to preserve compass bearings; for example 13 degrees east of north will be 13 degrees clockwise from the ray pointing toward the top of the map, at every point.  A mathematical consequence is the mapping is conformal, i.e. if two roads meet at a certain angle on the surface of the Earth, they will meet at that same angle on the map.  It also follows that at every point the vertical and horizontal scales are the same, so locally i.e. considering only a small part of the map, geographical features (shapes, angles) are well represented, which helps a lot in recognizing them on-the-field, or for local navigation in that small part only. For this reason, that projection (or a close variant) is used in several online mapping services, such as Google Maps, which means that it is frequently encountered by the general public. A straight line on the map corresponds to a course of constant bearing (direction), which was very useful for nautical navigation in the past (and thus made that projection very well-known).&lt;br /&gt;
&lt;br /&gt;
However, from a global point of view, this projection is radically incorrect in how it shows the size of landmasses (for instance, Antarctica and Greenland seem gigantic), and furthermore, it always excludes a small region around each pole (otherwise the map would be of infinite height), so it doesn't provide a complete solution for the problem of map projection. The comic implies that people who like that projection aren't very interested with map issues, and typically use what they are offered without thinking much about it.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Van der Grinten===&lt;br /&gt;
[[File:VanDerGrintenProjection.jpg|frame|The Van der Grinten projection]]&lt;br /&gt;
The {{w|Van der Grinten projection}} is not much better than the Mercator. It was adopted by {{w|National Geographic}} in 1922 and was used until they updated to the Robinson projection in 1988.&lt;br /&gt;
&lt;br /&gt;
The Van der Grinten projection is circular as opposed to the Mercator projection. The fictional person believes a circular map is more fitting to the real Earth's three-dimensional spherical nature because both are round. This belief fails to recognize that a two-dimensional circle has very little in common with the surface of a sphere, and thus this projection still causes a vast distortion of space and area.  Because of this, Randall implies the Van der Grinten enthusiast to be optimistic and childishly simple-minded (e.g. &amp;quot;you like circles&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Robinson===&lt;br /&gt;
[[File:RobinsonProjection.jpg|frame|The Robinson projection]]&lt;br /&gt;
The {{w|Robinson projection}} was developed by {{w|Arthur H. Robinson}} as a map that was supposed to look nice and is often used for classroom maps. National Geographic switched to this projection in 1988, and used it for ten years, switching to the {{w|Winkel tripel projection|Winkel-Tripel}} in 1998.&lt;br /&gt;
&lt;br /&gt;
{{w|The Beatles}} was a rock band that enjoyed great commercial success in the 1960s, and are widely considered the best act ever in the genre of popular music. The Beatles, coffee, and running shoes are all things that are very commonly enjoyed and largely uncontroversial, as well as being comforting.  Liking these specific things suggests an ordinary, easygoing lifestyle paralleled by the projection.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Dymaxion===&lt;br /&gt;
[[File:DymaxionProjection.jpg|frame|The Dymaxion projection]]&lt;br /&gt;
Also called the Fuller Map, the {{w|Dymaxion map}} takes a sphere and projects it onto an icosahedron, that is a polyhedron with 20 triangular faces. It is far easier to unwrap an icosahedron than it is to unwrap a sphere into a 2D object and has very little skewing of the poles. {{w|Buckminster Fuller}} was an eccentric futurist who believed, for example, that world maps should allow no conception of &amp;quot;up&amp;quot; or &amp;quot;down&amp;quot;. He was therefore more than happy to defy people's expectations about maps in the pursuit of mathematical accuracy.&lt;br /&gt;
&lt;br /&gt;
Randall associates the projection to geek subculture and niche markets:&lt;br /&gt;
*{{w|Isaac Asimov}} was an American science-fiction writer, who (as well as publishing many textbooks) is considered the father of the modern concept of robots. He invented the {{w|Three Laws of Robotics}}. He also worked on more than 500 books throughout his career.&lt;br /&gt;
*{{w|XML}} is the eXtensible Markup Language. It is used to represent data in a format that machines can read and understand, as well as being human-readable. In practice, XML is cumbersome to read.&lt;br /&gt;
*{{w|Vibram FiveFingers|Toed shoes}} are a [[1065: Shoes|favorite]] of Randall's to pick on. In society they are seen as a {{w|geek}} clothing item.&lt;br /&gt;
*Brought to the world by {{w|Dean Kamen}}, the {{w|Segway PT}} was supposed to be a device that changed the way cities were built. In reality, most principalities have put in place rules specifically against Segways, making them a frustration to own and use within the law (in some states in Australia, it is illegal to use them on public footpaths or roads). Also, the former owner of {{w|Segway Inc.}}, the late {{w|Jimi Heselden}}, accidentally rode his Segway off a cliff in 2010.&lt;br /&gt;
*At the time of comic release, 3D goggles, nowadays widely known as {{w|Virtual reality headset|VR headsets}}, were considered a gimmick at best. The original idea is as old as 3D graphics, but it never really took off until mid-2010s. Earlier products were very unwieldy and offered poor graphics quality, so no one took this technology seriously.&lt;br /&gt;
*{{w|Dvorak Simplified Keyboard|Dvorak}} is an alternate keyboard layout to {{w|QWERTY}}. According to legend, QWERTY was invented to help keep manual typewriters from jamming (by placing the most used keys far from each other) but Dr. {{w|August Dvorak}} performed many studies and found the mathematically optimal keyboard layout to reduce finger travel for right handed typists. While some claim Dvorak is technically better than QWERTY, QWERTY had become the standard. All the keyboards were laid out in QWERTY format, but a lot of software exists to remap the keys to DVORAK for those interested in typing faster.  Retraining the brain to use Dvorak takes perhaps a week.  It has become a [[:Category:Dvorak|recurrent theme]] on xkcd.&lt;br /&gt;
**It seems likely that Randall looked at this comic when he made the [[1784: Bad Map Projection: Liquid Resize]], and given that he then released a comic about Dvorak, [[1787: Voice Commands]], the week after that, it seem like  this old comic may also have inspired that Dvorak reference, see this [[1787: Voice Commands#Trivia|trivia item]].&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Winkel-Tripel===&lt;br /&gt;
[[File:Winkel-TripelProjection.jpg|frame|The Winkel Tripel projection]]&lt;br /&gt;
Proposed by Oswald Winkel in 1921, the {{w|Winkel tripel projection}} tried to reduce a set of three (German: Tripel) main problems with map projections: area, direction, and distance. The {{w|Kavrayskiy VII projection|Kavrayskiy projection}} is very similar to the Winkel Tripel and was used by the USSR, but very few in the Western world know of it.&lt;br /&gt;
&lt;br /&gt;
The comic links this projection to {{w|hipster}} subculture. The hipster stereotype is to avoid conforming to mainstream fashions. &amp;quot;Post-&amp;quot; refers to a variety of musical genres such as {{w|post-punk}}, {{w|post-grunge}}, {{w|post-minimalism}}, etc. that branch off of other genres.&lt;br /&gt;
&lt;br /&gt;
;Trivia&lt;br /&gt;
In German &amp;quot;Winkel-Tripel-Projektion&amp;quot; means Winkel's triple projection, and therefore the hyphen shouldn't be there: &amp;quot;Winkel Tripel&amp;quot; or &amp;quot;Winkel tripel&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Goode Homolosine===&lt;br /&gt;
[[File:GoodeHomolosineProjection.jpg|frame|The Goode Homolosine projection]]&lt;br /&gt;
The {{w|Goode homolosine projection}} takes a different approach to skewing a sphere into a roughly circular surface. An orange peel can be taken from an orange and flattened with fair success; this is roughly the procedure that {{w|John Paule Goode}} followed in creating this projection. Randall is suggesting that people who like this map also prefer relatively easy solutions to other things in life, despite those solutions having nuanced problems that are more difficult to address.&lt;br /&gt;
&lt;br /&gt;
Common people make arguments that if normal people would run the United States, then the US wouldn't be in the trouble it is. This is from the belief that career politicians are simply out to make money and will only act in the interest of their constituency when their continued easy life is threatened (usually around election time).&lt;br /&gt;
&lt;br /&gt;
Airline food is another, much maligned, problem. How do you store enough food to feed people on long airplane trips? What kind of food can be served in an enclosed, low-air-pressure environment? The common solution is to use some kind of prepackaged, reheated meal. Randall is saying that the people in favor of the Goode Homolosine wonder why the airlines don't simply order meals from the restaurants in the airport, store that food, and serve it, rather than using bland reheated food.&lt;br /&gt;
&lt;br /&gt;
Older cars burned oil like mad fiends, and oil back then would become corrosive to the innards of an engine, so oil had to be changed often. But, with the introduction of synthetic motor oil and better designed engines, new cars only need their oil changed about every 10,000 to 15,000 miles. A common conspiracy theory is that modern automobile oil manufacturers still recommend that car owners change their oil every 3,000-5,000 miles to &amp;quot;drum&amp;quot; up more business, even though that frequency is unnecessary.&lt;br /&gt;
&lt;br /&gt;
All of these references suggest that people who like the Goode Homolosine projection are fans of easy solutions to problems. However, the solutions would not necessarily work in practice. For instance: the restaurants might have trouble making enough food for the whole plane, and it could get cold before being served; the air conditions [http://www.nbcnews.com/health/one-reason-airline-food-so-bad-your-own-tastebuds-6C10823522 aboard planes] can affect taste, so airlines say they optimize for this; there is no such thing as a &amp;quot;normal&amp;quot; person, and if there were, he/she would have virtually no chance at actually getting into government office; and the Goode Homolosine projection, while mostly resembling a flattened orange peel as suggested by the earlier analogy, does indeed cut down on distortion, but also has serious problems of its own, such as leaving huge gaps of nothingness between the continents, making distances across the oceans difficult to visualize.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Hobo–Dyer===&lt;br /&gt;
[[File:Hobo-DyerProjection.jpg|frame|The Hobo–Dyer projection]]&lt;br /&gt;
The {{w|Hobo–Dyer projection}} was commissioned by Bob Abramms and Howard Bronstein and was drafted by Mick Dyer in 2002. It is a modified {{w|Behrmann projection}}. The goal was to be a more visually pleasing version of the Gall–Peters.&lt;br /&gt;
&lt;br /&gt;
As is discussed in the Gall–Peters explanation, the Gall–Peters was developed to be equal area, so that economically disadvantaged areas can at least take comfort in the fact that their country is represented correctly by area on maps.&lt;br /&gt;
&lt;br /&gt;
Randall associates the Hobo–Dyer projection to &amp;quot;crunchy granola&amp;quot; — a stereotype associated with vegetarianism, environmental activism, anti-war activism, liberal political leanings, and some traces of {{w|hippie}} culture.&lt;br /&gt;
&lt;br /&gt;
With feminism becoming mainstream and alternative genders being more widely accepted, some have begun to invent gender-neutral pronouns so that when referring to a person whose gender is not known they cannot be offended by being referred to by the wrong pronouns. In {{w|Middle English}} 'they' and 'their' were accepted gender-less pronouns that could replace 'he', 'she' as well as be used to represent a crowd, but this usage is considered by some to be grammatically incorrect because of the plural/singular debate ([http://www.merriam-webster.com/video/0033-hisher.htm stupid Victorian Grammarians!]). There have been {{w|gender-neutral pronoun#Invented pronouns|many attempts at popularizing invented gender-neutral pronouns}} and they are beginning to achieve some degree of success in the mainstream.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Plate Carrée===&lt;br /&gt;
[[File:PlateCarreeProjection.jpg|frame|The Plate Carrée projection]]&lt;br /&gt;
Also known as the {{w|Equirectangular projection}}, it has been in use since, apparently, 100 AD. The benefit of this projection is that latitude and longitude can be used as x,y coordinates. This makes it especially easy for computers to graph data on top of it.&lt;br /&gt;
&lt;br /&gt;
According to the comic, the projection appeals to people who find much beauty in simplicity.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===A Globe!===&lt;br /&gt;
[[File:GlobeProjection.jpg|frame|The Globe &amp;quot;projection&amp;quot;]]&lt;br /&gt;
In any good discussion there has to be at least one smart-ass. This is a comic about map projections, that is, the science of taking a sphere and flattening it into 2 dimensions. The smart-ass believes that we shouldn't even try: a sphere is, tautologically, the perfect representation of a sphere.&lt;br /&gt;
&lt;br /&gt;

A globe is, of course, the &amp;quot;map projection&amp;quot; used by {{w|Google Earth}}, and recently by other mapping software as computers and phones get increasingly powerful 3D graphics.&lt;br /&gt;

===Waterman butterfly===&lt;br /&gt;
[[File:WatermanButterflyProjection.jpg|frame|The Waterman Butterfly projection]]&lt;br /&gt;
Similar to the Dymaxion, the {{w|Waterman butterfly projection}} turns a sphere into an octahedron, and then unfolds the net of the octahedron, which was devised by mathematician {{w|Waterman polyhedron|Steve Waterman}} based upon the work of {{w|Bernard J.S. Cahill}}.&lt;br /&gt;
&lt;br /&gt;
Bernard Cahill published a [http://www.genekeyes.com/B.J.S._CAHILL_RESOURCE.html butterfly map] in 1909. Steve Waterman probably has the only extant &amp;quot;ready to go&amp;quot; map following the same general principles, though Gene Keys may not be far behind. Waterman has a poem with graphics in a similar vein to this xkcd comic that is worth reading.[http://web.archive.org/web/20120118095915/http://watermanpolyhedron.com/worldmap.html]&lt;br /&gt;
&lt;br /&gt;
[http://www.progonos.com/furuti/MapProj/Normal/ProjPoly/projPoly2.html Polyhedral projections] like Cahill, Dymaxion or Waterman typically offer better accuracy of size, shape and area than flat projections, at the expense of compass directionality, connectedness, and other complications.&lt;br /&gt;
&lt;br /&gt;
The joke is that the person responding deeply understands map projections; anyone who knows of this projection is a person that Randall would like to get to know.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===Peirce quincuncial===&lt;br /&gt;
[[File:PeirceQuincuncialProjection.jpg|frame|The Peirce Quincuncial projection]]&lt;br /&gt;
The {{w|Peirce quincuncial projection}} was devised by {{w|Charles Sanders Peirce}} in 1879 and uses {{w|complex analysis}} to make a {{w|conformal mapping}} of the Earth, that conforms except for four points which would make up the midpoints of sides and lie on equator (the equator is represented by a square and the corners connect the sides in the middle.)&lt;br /&gt;
&lt;br /&gt;
{{w|Inception}} was a 2010 movie about {{w|meta}} {{w|lucid dream}}ing. It has a complex story that is difficult to follow and leaves the viewer with many questions at the end, and almost needs to be watched multiple times to be understood.&lt;br /&gt;
&lt;br /&gt;
The human brain is not well developed to deal with oddly obvious things. One example is that everyone has a skeleton, but everyone is surprised to see a part of their body represented by an X-ray. Another is the fascinating complexity of the human hand, a machine which is amazingly complex, driven by a complex interplay of electrical and chemical signals; yet is the size of the hand and so useful. A fascination with or fixation on [http://tvtropes.org/pmwiki/pmwiki.php/Main/ContemplatingYourHands such thoughts] is often associated with an altered state of mind brought on by marijuana consumption. Therefore, Randall may be implying that this map would appeal to stoners.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Gall–Peters===&lt;br /&gt;
[[File:Gall-PetersProjection.jpg|frame|The Gall–Peters projection]]&lt;br /&gt;
The {{w|Gall–Peters projection}} is mired in controversy, surprising for a map. {{w|James Gall}}, a 19th-century clergyman, presented this projection in 1855 before the {{w|British Association for the Advancement of Science}}. In 1967, the filmmaker {{w|Arno Peters}} created the same projection and presented it to the world as a &amp;quot;new invention&amp;quot; that put poorer, less powerful countries into their rightful proportions (as opposed to the Mercator). Peters played the marketing game and got quite a few followers of his map by saying it had &amp;quot;absolute angle conformality,&amp;quot; &amp;quot;no extreme distortions of form,&amp;quot; and was &amp;quot;totally distance-factual&amp;quot; in an age when society was very concerned about social justice. All of these claims were in fact false. The Mercator projection distorts size in favor of shape, and Gall-Peters distorts shape in favor of size, being especially inaccurate at the equator and the poles.&lt;br /&gt;
&lt;br /&gt;
Anyone who loves such a politically charged map that has become popular by way of marketing stunts, Randall would rather not have anything to do with.&lt;br /&gt;
&lt;br /&gt;
{{clear}}&lt;br /&gt;
&lt;br /&gt;
===Title text===&lt;br /&gt;
The title text makes a joke that goes to the familiar meme from ''{{w|CSI: Miami}}'', in which the star, David Caruso starts a sentence, then puts on his sunglasses and ends the sentence with a corny pun. In this case, the pun is on {{w|map projection}} and {{w|projection (psychology)|projection}} in psychology. Psychological projection is an unconscious defense mechanism wherein a person who is uncomfortable with their own impulses denies having them and attributes them to other people, and blames these people for these impulses. The Sunglasses internet meme has been used [[:Category:Puts on sunglasses|in other comics]] as well.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1886&lt;br /&gt;
| date      = September 6, 2017&lt;br /&gt;
| title     = Typing Notifications&lt;br /&gt;
| image     = typing_notifications.png&lt;br /&gt;
| titletext = Over the years I've decided I'd rather have them on than not, but I'm glad there aren't &amp;quot;has opened a blank note to compose a reply to you&amp;quot; notifications.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Randall]] has sent an instant message to someone and is now watching the screen expecting a reply. The message contains simple questions about a show Randall had undertaken and he insists on an honest answer. The phone indicates that the respondent is typing a response, but then pauses, resumes typing, and pauses a second time, before sending a simple &amp;quot;It was great!&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Typing notifications, often called &amp;quot;typing awareness indicator&amp;quot;, is a feature of some {{w|instant messaging}} systems. It lets you know when the other person in a conversation is typing and preparing a reply. It may appear in different forms, like the literal text &amp;quot;[Contact] is typing.&amp;quot; or often has a empty answer (possibly a different color) containing three animated dots. It gives the sender confidence that their message has been received and the other one is working on a reply.&lt;br /&gt;
&lt;br /&gt;
When the final response is received it is anodyne &amp;quot;It was great&amp;quot;, suggesting that the first two deleted drafts could be far more critical. The fact that you know that a message has been deleted or edited twice provokes you to imagine what the deleted drafts may have contained. The issue with typing notifications that Randall is talking about might also just be the difficulty to interpret them. The distant contact might just have been doing something else at the same time, started typing in the wrong conversation, or corrected a typo, but because Randall has interpreted the long pauses the same way one would read face-to-face interactions, the typing notifications make it seem like they weren't honest.&lt;br /&gt;
&lt;br /&gt;
If one partner of a conversation takes their sweet time to reply, possibly deleting their text and starting from scratch as shown in this comic, the typing notification feature can lead to anxiety, as the person waiting for a response starts to overthink the issue. Thoughts come to mind like the other person might not be honest, try to carefully word a sensitive subject or not care enough about you to quickly reply. If finally the answer arrives and consists of just a laconic &amp;quot;ok&amp;quot; or similar, these feelings become even stronger, leading to thoughts like the other person is trying to hide something. This phenomenon has become so widespread that many people have written about it in newspapers and blogs, calling it [https://www.nytimes.com/2014/08/31/fashion/texting-anxiety-caused-by-little-bubbles.html texting anxiety].&lt;br /&gt;
&lt;br /&gt;
The caption below the screens summarizes that what Randall dislikes the most about these systems of notification that the other party on the conversation is actively working on a reply is the lengthly alternation between indications that the other party is composing a reply, amidst pauses wherein one presumes the other party is thinking carefully about what they are wanting to say, then more typing as in response to their deep thinking, etc. until at the end of this extended period when one expects the other side to have written a book's worth of notes given the time and work they appear to have dedicated to the reply -- and all they get is a simple 3-word reply.  It leaves him wondering what all the other party really typed, and really thought, that they ended up not sending.&lt;br /&gt;
&lt;br /&gt;
One way around giving your text receiver texting anxiety would be to open a blank note and work out what you want to say there. Since you're not typing in the messaging app, there's no typing notification.  &lt;br /&gt;
&lt;br /&gt;
In the title text, Randall expresses that he likes to watch when the recipient reacts and is trying to write an answer but he's also happy to not receive notifications that the texter is composing a response in a blank note file. Typically, one composes responses in blank notes when they need to be careful or thoughtful about how they respond (as well as avoid alerting the recipient, via the notifications, that they've received their text and are preparing a response). If Randall were to be notified about such actions, it would confirm his above fears that the writer was being tactful and guarded in their response, which would just lead to more anxiety about what they were trying to hide.&lt;br /&gt;
&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Megan]] is complaining to [[Hairbun]] about her easy access to infuriating national news stories and bad opinions (editorial articles and commentary) and worries that it may be having a negative effect on her, perhaps by promoting misinformation, by distraction, or by prompting adverse emotional reaction to content; she muses that, in some way or another, this habit is probably doing some sort of damage to her brain's wiring, training it to think in ways that are not necessarily good. While the capacity of the brain to change and adapt to a person's daily habits is, like most neurological phenomena, as yet not very well understood, it's clear that something of the sort exists--scientists refer to this capacity as &amp;quot;[https://www.medicinenet.com/script/main/art.asp?articlekey=40362 neuroplasticity].&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Hairbun sarcastically tells Megan that things were different in her time, implicitly stating that access to infuriating stories via newspapers took only a tiny bit more time and effort during a morning routine compared to accessing them via the Internet.&lt;br /&gt;
&lt;br /&gt;
Megan counters this idea and says that while it is true that newspapers provided the sort of national news she is being provoked by, they also had much more ''local'' news mixed in (which may be of a lighter nature, sometimes referred to in a derogatory sense as &amp;quot;fluff&amp;quot; news pieces), to which Hairbun agrees.&lt;br /&gt;
&lt;br /&gt;
Megan also raises the point that bad opinions were not granted wide distribution. Hairbun is rather less quick to agree to this, and suggests that Megan not check that, revealing that Megan’s assertion isn’t entirely true. Indeed, before the Internet, newspapers were a common medium for expressing opinions, either by local columnists or average citizens via letters to the editor, and they, as with any body of opinions throughout history, were frequently noxious or ill-informed.&lt;br /&gt;
&lt;br /&gt;
The title text takes another jab at newspapers as a supposedly superior source of news. Supporting your local paper is generally considered a positive action, as it is often the best or only source for local news (national media can't focus on smaller areas, and radio/television often lacks print media's focus on investigative journalism). However, in recent years, many seemingly independent local newspapers in major cities have been bought up by financial groups rather than traditional publishing companies, and their effect on the industry as a whole has been controversial. Most notably, hedge fund groups often attempt to make newspapers profitable by [https://www.bloomberg.com/news/articles/2018-05-22/the-hard-truth-at-newspapers-across-america-hedge-funds-are-in-charge cutting costs and downsizing], at the expense of quality reporting; critics call such hedge fund groups [https://www.washingtonpost.com/lifestyle/style/as-a-secretive-hedge-fund-guts-its-newspapers-journalists-are-fighting-back/2018/04/12/8926a45c-3c10-11e8-974f-aacd97698cef_story.html?utm_term=.d4e6ff7d3058 &amp;quot;vulture capitalists&amp;quot;] who are throttling newspapers for short-term profit, without any thought of long-term viability or public service. The owners of the fund may also be unethical or controversial for other reasons. Thus, the standard well-meaning suggestion of supporting your local paper may no longer be good advice.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by a SIMPLE APPLE - needs an explanation of &amp;quot;platonic ideal exchange&amp;quot;.  Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
[[Megan]] is about to buy an apple at a grocery store when she is surprised that the price is exactly one dollar. In most cases in the US, {{w|Sales taxes in the United States|sales tax}} must be taken into account, but most states exempt food sold in grocery stores, so the price comes out to a round value. This is so strange for Megan that it throws her for a loop. Buying one apple for one dollar feels to her more like a simplified, imaginary ''idea'' of a transaction (a &amp;quot;{{w|Platonic ideal}}&amp;quot;) than like something that could actually happen in real life.&lt;br /&gt;
&lt;br /&gt;
Megan likely shares Randall's background of engineering and math.  When learning science, engineering, and math in the education system, one studies examples where every number is some round value, and all situations are simplified to the barest essentials so as to demonstrate the ideas being taught.  Then, when doing real problems in the real world, one spends the rest of one's life almost never being able to use the simplified tricks demonstrated as examples in school, because when math is used to describe the natural world, nothing is ever a round number unless by design.&lt;br /&gt;
&lt;br /&gt;
The harsh difference between being able to buy an apple for a dollar at this quaint store, and having to deal with arbitrary decimals and numbers in the rest of life could be touching on Megan's life experience of the world not being what she was prepared for, resulting in her intense response.  Regardless if that is true or not, it seems the cashier is unable to figure out how to handle it (or does not want to), and raises the price to an arbitrary non-rounded value, which has the intended effect of halting Megan's outburst.&lt;br /&gt;
&lt;br /&gt;
Megan's references refer to common parameters used in solving science or math questions. A {{w|Frictionless plane}} is a scenario from the writings of Galileo to calculate the movement of an object down an {{w|inclined plane}}. However, his equations did not account for {{w|friction}}.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;A train leaving Chicago at 40 mph&amp;quot; refers to common math questions, involving trains and solving for the distance required to overtake said train, although this problem involves the rather unrealistic assumption that the train's velocity keeps constant. Like the frictionless plane, this is a common simplification that allows the problem to be solved with quite simple techniques, just like having round quantities (e.g. 1 dollar/apple) eases arithmetic problems. See also [[669: Experiment]]. Apples themselves are commonly used as units for math problems, including problems as simple as basic arithmetic.&lt;br /&gt;
&lt;br /&gt;
The comic repeats a common theme in the strip of engineers and computer scientists trying to apply their technical experience to social situations.  In this case, the conversation partner is &amp;quot;normal&amp;quot;, and does not respond supportively, which is a common situation in the real world and a possible point of empathy with readers.&lt;br /&gt;
&lt;br /&gt;
It seems that according to the title text, Megan only has (or only wants to spend) one dollar, so she would not be able to buy a whole apple at the new price (0.4608 × $2.17 ≈ $1). Stores usually sell whole apples, so asking for a fraction of one is not likely to work out.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Megan is at the store counter, behind which Ponytail (the cashier) is waiting.]&lt;br /&gt;
:Megan: Just this apple, thanks.&lt;br /&gt;
:Ponytail: That will be one dollar.&lt;br /&gt;
:Megan: Exactly? No tax or anything?&lt;br /&gt;
:Ponytail: That's right.&lt;br /&gt;
&lt;br /&gt;
:[Megan stares at the apple in a frameless panel.]&lt;br /&gt;
&lt;br /&gt;
:[Scene zooms in on Megan.]&lt;br /&gt;
:Ponytail: ...Is that a problem?&lt;br /&gt;
:Megan: It's just weird to realize that every other transaction in my life will be more complicated than this.&lt;br /&gt;
&lt;br /&gt;
:[Scene changes focus to Ponytail behind the counter.]&lt;br /&gt;
:Megan: This is like a platonic ideal exchange. An apple for a dollar.&lt;br /&gt;
:Ponytail: I see.&lt;br /&gt;
&lt;br /&gt;
:[Scene changes back to Megan, once again lost in profound contemplation of the apple.]&lt;br /&gt;
:Megan: Are we on a frictionless plane? Is a train leaving Chicago at 40 mph? ''Should I solve for something??''&lt;br /&gt;
:Ponytail: Okay, apples are $2.17 now.&lt;br /&gt;
:Megan: That's... probably better for us both.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1163&lt;br /&gt;
| date      = January 21, 2013&lt;br /&gt;
| title     = Debugger&lt;br /&gt;
| image     = debugger.png&lt;br /&gt;
| titletext = It can take a site a while to figure out that there's a problem with their 'report a bug' form.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] mentions to [[Megan]] that he can't understand how his mind works, the same mind he uses to understand how things work, and he's not sure if this is a problem. In other words, if he can't understand how his mind works, then how can he tell that it does in fact work and that his perception of reality is accurate? Ordinarily he would use his mind to figure it out, but if his mind really doesn't work, then he'll probably never determine that his mind doesn't work. Not only that, he can't even trust his brain to tell him if his inability to understand his own brain is an issue. Understandably, he's a little unsure of how he should feel about this.&lt;br /&gt;
&lt;br /&gt;
Per the comic title, a {{w|Debugger|debugger}} is a piece of software used by programmers to find {{w|Software bug|bugs}} in the {{w|Application software|applications}} they are making. The title is an allusion to that debuggers are very much like our brains in the aspect described above - most programmers don't understand how debuggers internally work, and they can't be sure that debugger is bug-free - if there is a bug in the debugger itself, it can't be accurately used to find bugs.&lt;br /&gt;
&lt;br /&gt;
The title text alludes to the above problem, in that if a website's &amp;quot;report a bug&amp;quot; page is buggy to a degree that it prevents the actual reporting of a bug, then users cannot use the form to report that the form itself is broken. Thus it can take quite some time before the site administrators realize this error, if they do at all, as unless they test it themselves, the administrators are likely relying on users to report problems they find, which they can't, making it appear as if there are no problems. This is somewhat analogous to the &amp;quot;brain&amp;quot; dilemma in the main comic, where the usual problem-pondering and resolving method itself can have a problem, but there is no straightforward way to tell.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
{{comic&lt;br /&gt;
| number    = 1999&lt;br /&gt;

| title     = Selection Effect&lt;br /&gt;
| image     = selection_effect.png&lt;br /&gt;
| titletext = fMRI testing showed that subjects who don't agree to participate are much more likely to escape from the machine mid-scan.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
The title refers to the effect in scientific fields where the people who agree to work with a researcher can affect the outcome.  For example if I said I wanted to do a study on an embarrassing condition, people who know they have it might be more apprehensive and thus not participate.  This can skew the results to say that the condition is rarer than it is. This is called the {{w|selection bias}}, or more precisely, the {{w|self-selection bias}}. Ironically, to avoid any selection bias, researchers would have to force their ''randomly'' selected subjects to participate in their study, but yet the uneasiness shown by the mandatory subjects again skews the results.&lt;br /&gt;
&lt;br /&gt;
Ponytail says that people who agree to be in a study at their lab are less likely to attempt to escape. The only way Ponytail could have come to this conclusion is if she compared those people to people who did not agree to be in the study. This implies that Ponytail has recently kidnapped people for a study, and that most of the people she kidnapped called the police, as one should do when being kidnapped{{Citation needed}}. This makes sense, since if you agreed to the study, you know why you are there, while if you didn't, you may have been kidnapped. &lt;br /&gt;
&lt;br /&gt;
The comic shows Ponytail being allowed to present the results of this study at a conference; reputable scientific journals and conferences should not legitimize studies that clearly violate their ethical norms, such as by failing to obtain informed consent from human subjects before experimenting on them.  Unfortunately, involuntary studies are published and presented, one of the most well-known recent examples being [http://america.aljazeera.com/articles/2014/6/30/facebook-ethics-labratsemotionalcontagion.html Facebook's emotional contagion study].  It is not clear how many people who did agree to participate may have attempted to call the police for assistance regardless; compare the [https://en.wikipedia.org/wiki/Stanford_prison_experiment Stanford Prison Experiment]. This is similar to previous comics where obvious things are presented in obfuscated, scientific ways.&lt;br /&gt;
&lt;br /&gt;
The title text says that people who didn't agree to go inside an MRI machine are more likely to escape the machine mid-scan. Again, this makes sense, because being put somewhere against your will makes you unsure what is going on, making you try to find a way out.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Ponytail stands on a podium giving a presentation in front of a chart with some box plots.]&lt;br /&gt;
:Ponytail: Our research shows that compared to the overall population, people who agree to participate in scientific studies are significantly less likely to call the police to rescue them from our lab.&lt;br /&gt;

&lt;br /&gt;
[[Megan]] is complaining to [[Hairbun]] about her easy access to infuriating national news stories and bad opinions (editorial articles and commentary) and worries that it may be having a negative effect on her, perhaps by promoting misinformation, by distraction, or by prompting adverse emotional reaction to content; she muses that, in some way or another, this habit is probably doing some sort of damage to her brain's wiring, training it to think in ways that are not necessarily good. While the capacity of the brain to change and adapt to a person's daily habits is, like most neurological phenomena, as yet not very well understood, it's clear that something of the sort exists--scientists refer to this capacity as &amp;quot;[https://www.medicinenet.com/script/main/art.asp?articlekey=40362 neuroplasticity].&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Hairbun sarcastically tells Megan that things were different in her time, then states how access to infuriating stories via newspapers required only a tiny bit more time and effort during a morning routine.&lt;br /&gt;
&lt;br /&gt;
Megan counters this idea and says that while it is true that newspapers provided the sort of national news she is being provoked by, they also had much more ''local'' news mixed in (which may be of a lighter nature, sometimes referred to in a derogatory sense as &amp;quot;fluff&amp;quot; news pieces), to which Hairbun agrees.&lt;br /&gt;
&lt;br /&gt;
Megan also raises the point that bad opinions were not granted wide distribution. Hairbun is rather less quick to agree to this, and suggests that Megan not check that, revealing that Megan’s assertion isn’t entirely true.&lt;br /&gt;
&lt;br /&gt;
The title text takes another jab at newspapers as a supposedly superior source of news. Supporting your local paper is generally considered a positive action, as it is often the best or only source for local news (national media can't focus on smaller areas, and radio/television often lacks print media's focus on investigative journalism). However, in recent years, many seemingly independent local newspapers in major cities have been bought up by financial groups rather than traditional publishing companies, and their effect on the industry as a whole has been controversial. Most notably, hedge fund groups often attempt to make newspapers profitable by [https://www.bloomberg.com/news/articles/2018-05-22/the-hard-truth-at-newspapers-across-america-hedge-funds-are-in-charge cutting costs and downsizing], at the expense of quality reporting; critics call such hedge fund groups [https://www.washingtonpost.com/lifestyle/style/as-a-secretive-hedge-fund-guts-its-newspapers-journalists-are-fighting-back/2018/04/12/8926a45c-3c10-11e8-974f-aacd97698cef_story.html?utm_term=.d4e6ff7d3058 &amp;quot;vulture capitalists&amp;quot;] who are throttling newspapers for short-term profit, without any thought of long-term viability or public service.

&lt;br /&gt;
[[Megan]] is complaining to [[Hairbun]] about her easy access to infuriating national news stories and bad opinions (editorial articles and commentary) and worries that it may be having a negative effect on her, perhaps by promoting misinformation, by distraction, or by prompting adverse emotional reaction to content; she muses that, in some way or another, this habit is probably doing some sort of damage to her brain's wiring, training it to think in ways that are not necessarily good. While the capacity of the brain to change and adapt to a person's daily habits is, like most neurological phenomena, as yet not very well understood, it's clear that something of the sort exists--scientists refer to this capacity as &amp;quot;[https://www.medicinenet.com/script/main/art.asp?articlekey=40362 neuroplasticity].&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Hairbun sarcastically tells Megan that things were different in her time, then states how access to infuriating stories via newspapers required only a tiny bit more time and effort during a morning routine.&lt;br /&gt;
&lt;br /&gt;
Megan counters this idea and says that while it is true that newspapers provided the sort of national news she is being provoked by, they also had much more ''local'' news mixed in (which may be of a lighter nature, sometimes referred to in a derogatory sense as &amp;quot;fluff&amp;quot; news pieces), to which Hairbun agrees.&lt;br /&gt;
&lt;br /&gt;
Megan also raises the point that bad opinions were not granted wide distribution. Hairbun is rather less quick to agree to this, and suggests that Megan not check that, revealing that Megan’s assertion isn’t entirely true.&lt;br /&gt;
&lt;br /&gt;
The title text takes another jab at newspapers as a supposedly superior source of news. Many seemingly independent local newspapers in major cities have been bought up by financial groups rather than traditional publishing companies, and their effect on the industry as a whole has been controversial. Most notably, hedge fund groups often attempt to make newspapers profitable by [https://www.bloomberg.com/news/articles/2018-05-22/the-hard-truth-at-newspapers-across-america-hedge-funds-are-in-charge cutting costs and downsizing], at the expense of quality reporting; critics call such hedge fund groups [https://www.washingtonpost.com/lifestyle/style/as-a-secretive-hedge-fund-guts-its-newspapers-journalists-are-fighting-back/2018/04/12/8926a45c-3c10-11e8-974f-aacd97698cef_story.html?utm_term=.d4e6ff7d3058 &amp;quot;vulture capitalists&amp;quot;] who are throttling newspapers for short-term profit, without any thought of long-term viability or public service. Thus, the standard well-meaning suggestion of supporting your local paper may no longer be good advice.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Megan, looking on a smartphone in her hand, and Hairbun are standing together and talk.]&lt;br /&gt;
:Megan: Every morning, before my eyes even focus all the way, I read a bunch of infuriating national news stories and bad opinions. I wonder what this is doing to my brain.&lt;br /&gt;
:Megan: It's probably not great.&lt;br /&gt;
&lt;br /&gt;
:[Zoom in to the head of Hairbun.]&lt;br /&gt;
:Hairbun: Back in my day, we had to pay people to '''''print out''''' infuriating news stories and bring them to our door. And we waited until we had stumbled out to the '''''kitchen''''' to read them.&lt;br /&gt;
:Hairbun: '''''Totally''''' different.&lt;br /&gt;
&lt;br /&gt;
:[Frameless panel, zoom out on both while Megan has lowered her hand holding the phone.]&lt;br /&gt;
:Megan: OK, fair. But newspapers at least had more local news mixed in, right?&lt;br /&gt;
:Hairbun: Yeah, true.&lt;br /&gt;
&lt;br /&gt;

| number    = 1873&lt;br /&gt;
| date      = August 7, 2017&lt;br /&gt;
| title     = Email Reply&lt;br /&gt;
| image     = email_reply.png&lt;br /&gt;
| titletext = I would be honored, but I know I don't belong in your network. The person you invited was someone who had not yet inflicted this two-year ordeal upon you. I'm no longer that person.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] is sitting at his desk writing an {{w|email}}. He is responding to Kevin, who sent him an email ''two years'' ago. Cueball is so far behind in responding to his email, he goes to great lengths to apologize for it. Instead of blaming the email culture which creates enormous quantities of messages, he blames himself for not keeping up. Failing to answer emails is a common symptom of general anxiety disorder, a problem which can snowball out of control as more and more emails go unread or unanswered.&lt;br /&gt;
&lt;br /&gt;
At this point in the email, the reader assumes that Kevin's message really demanded a faster response, being personal and timely. Then Cueball reveals that the email is just the ubiquitous {{w|LinkedIn}} invitation. LinkedIn is a professional networking site notorious for inundating its users with emails inviting them to connect to other users (frequently people the user has little-to-no connection to), as well as any email contacts of their users whether or not they actually belong to LinkedIn themselves. Thus, an invitation to connect to LinkedIn is most often immediately deleted or ignored. A less socially anxious person who understands the irrelevance of such an email would not worry about failing to respond to such a request at all, and certainly would not pour his heart out in apology for failing to reply.&lt;br /&gt;
&lt;br /&gt;
The title text makes Cueball's overinvestment in the email even more exaggerated, suggesting that Cueball is rejecting the invitation not because of its pointlessness, but because he feels that as a bad friend who doesn't respond to emails, he is no longer even worthy of it. &lt;br /&gt;
&lt;br /&gt;
One could interpret the letter as a passive-aggressive lashing out, but that does not seem to be in character for [[Cueball]]. Had the character worn a [[Black Hat]] though...&lt;br /&gt;
&lt;br /&gt;
Cueball's difficulty in checking his email was previously addressed in [[1783: Emails]] (trivia: the comic numbers 1783 and 1873 are anagrammatic).&lt;br /&gt;
&lt;br /&gt;
This is the fourth comic within a year where [[Randall]] uses &amp;quot;Kevin&amp;quot; as a go-to-name, although it was half a year since last time in [[1795: All You Can Eat]]. See details in that comics [[1795:_All_You_Can_Eat#Kevin|trivia]].&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball sits at a desk, typing on a laptop. The following message is displayed above him:]&lt;br /&gt;
&lt;br /&gt;
:Dear Kevin,&lt;br /&gt;
&lt;br /&gt;
:I'm sorry it's taken me two years to reply to your email. I've built up so much stress and anxiety around my email inbox; it's an unhealthy dynamic which is more psychological than technical. I've tried one magical solution after another, and as each one has failed, deep down I've grown more certain that the problem isn't email &amp;amp;ndash; it's me.&lt;br /&gt;
&lt;br /&gt;
:Regardless, these are my issues, not yours; you're my friend, and I owe you the basic courtesy of a response. I apologize for my neglect, and I hope you haven't been too hurt by my failure to reply.&lt;br /&gt;
&lt;br /&gt;
:Anyway, I appreciate your invitation to join your professional network on LinkedIn, but I'm afraid I must decline...&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is making fun of the various names we give &amp;quot;generations&amp;quot; while also predicting some future names. The release of this comic coincides with the [http://www.pewresearch.org/fact-tank/2018/03/01/defining-generations-where-millennials-end-and-post-millennials-begin/ Pew Research Center's recent announcement that they have decided where the Millennial generation ends].&lt;br /&gt;
&lt;br /&gt;
Each generation listed is exactly 18 years long, which is the approximate length of each &amp;quot;generation&amp;quot; anyway (given that coincidentally, there are exactly 54 intermediate years between the end of World War II and the New Millennium). A number of the entries are parodies of the terms &amp;quot;Generation X,&amp;quot; &amp;quot;Generation Y,&amp;quot; etc., by substituting other letters or characters that would seem emblematic of the time period. &lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! scope=&amp;quot;col&amp;quot;| Generation&lt;br /&gt;
! scope=&amp;quot;col&amp;quot;| Time period&lt;br /&gt;
! scope=&amp;quot;col&amp;quot;| Explanation&lt;br /&gt;
|-&lt;br /&gt;
| The Founders&lt;br /&gt;
| 1730&amp;amp;nbsp;-&amp;amp;nbsp;1747&lt;br /&gt;
| Most of the {{w|Founding Fathers of the United States|United States' Founding Fathers}} were born in this period.  (But not all: Benjamin Franklin, for instance, was born two generations prior, in 1706.)&lt;br /&gt;
|-&lt;br /&gt;
| Generation ƒ&lt;br /&gt;
| 1748 - 1765&lt;br /&gt;
| ƒ was used to represent {{w|Long s|&amp;quot;long s&amp;quot;}} in the typography used in Colonial America.  It can be seen in many historical documents from the period.  It is also the symbol that represented the {{w|Dutch guilder|guilder}}, the currency of the Netherlands from the 17th century until 2002.&lt;br /&gt;
|-&lt;br /&gt;
| The Adequate Generation&lt;br /&gt;
| 1766 - 1783&lt;br /&gt;
| Randall apparently found nothing notable about this generation, positive or negative. This is a reference to the Greatest Generation, below.&lt;br /&gt;
|-&lt;br /&gt;
| Generation Æ&lt;br /&gt;
| 1784 - 1801&lt;br /&gt;
| Æ is the {{w|Æ|diphthong}} Aesh - its name sounds like X, though it is pronounced as a long e or IPA /æ/.  This character is commonly transcribed differently into British English and American English as ae and e respectively making a difference in spelling in words such as encyclopaedia/encylopedia.  One of the key influences on this is Webster's dictionary, first published 1828.&lt;br /&gt;
|-&lt;br /&gt;
| The generation we cut a lot of slack because they produced Lincoln&lt;br /&gt;
| 1802 - 1819&lt;br /&gt;
| Abraham Lincoln was born in 1809, and is regarded as one of the best presidents of all time. The comic states that the other people born in this generation were &amp;quot;cut a lot of slack&amp;quot; because of him. As with the Oops, one of us is Hitler generation, it is absurd to define an entire generation by defining its most famous member.&lt;br /&gt;
|-&lt;br /&gt;
| The&amp;amp;nbsp;Gilded&amp;amp;nbsp;Generation&lt;br /&gt;
| 1820 - 1837&lt;br /&gt;
| {{w|Gilded Generation (Strauss–Howe theory)| So named under the Strauss-Howe generation theory}}, though they use the time period 1822-1842 instead.  This likely refers to the &amp;quot;{{w|Gilded Age}}&amp;quot; of American history, roughly the last three decades of the 19th century.&lt;br /&gt;
|-&lt;br /&gt;
| The Second-Greatest Generation&lt;br /&gt;
| 1838 - 1855&lt;br /&gt;
|&lt;br /&gt;
This is a reference to the Greatest Generation, below, and could be implying a similarity between the accomplishments and sacrifices of this generation - who fought in the U.S. Civil War and who passed the 13th, 14th, and 15th Amendments to the U.S. Constitution - to those of the Greatest Generation. There is also some humor in the name: what Randall means is that this generation was, supposedly, second best in terms of its greatness. However, the wording could be interpreted to mean that they are chronologically the second generation to be called &amp;quot;greatest&amp;quot;, even though they actually were born first.&lt;br /&gt;
|-&lt;br /&gt;
| Generation – • • –&lt;br /&gt;
| 1856 - 1873&lt;br /&gt;
| – • • – is the letter X in {{w|Morse_code|International Morse Code}}. This is an old-timey version of Gen Xers, mirrored by the later &amp;quot;More Gen-Xers somehow.&amp;quot; This is also a reference to the rise of {{w|telegraphy}}, popular during this time period.&lt;br /&gt;
|-&lt;br /&gt;
| The kids who died in the Gilded Generation's factories and mines&lt;br /&gt;
| 1874 - 1891&lt;br /&gt;
| {{w|Child labour #The Industrial Revolution|Child labor}} had been widely used since before the start of the Industrial Revolution, but this is when people started doing something about it - and also, when the need for an educated workforce arose, applying substantial economic pressure on societies to put children in school instead.  It would be more accurate to label this generation, &amp;quot;The kids who stopped dying in the Gilded Generation's factories and mines&amp;quot;.&lt;br /&gt;
|-&lt;br /&gt;
| Oops, one of us is Hitler&lt;br /&gt;
| 1892 - 1909&lt;br /&gt;
| {{w|Adolf Hitler}}, possibly the most hated (and, by most definitions, evil) man in living human memory as of this comic's posting, was born during in 1889.  Aside from the fact that this places him in the previous generation, it seems beyond silly to blame everyone else who was born during this period for being born in the same generation as him.  Among those who eventually heard of him (thus, excluding those in isolated areas or who died before he rose to power), the vast majority of them would not hear of him until well after 1909. In reality, this generation is known as the {{w|Lost Generation}}, though the dates are somewhat skewed.&lt;br /&gt;
|-&lt;br /&gt;
| The Greatest Generation&lt;br /&gt;
| 1910 - 1927&lt;br /&gt;
| Named by journalist {{w|Tom Brokaw}} in 1998 in {{w|The Greatest Generation|a book of the same name}}, this is the first generation on the list to have a real, commonly accepted name, and was named as such due to being the generation that survived the hardships of the {{w|Great Depression}} immediately before being drafted to fight in {{w|World War II}}.&lt;br /&gt;
|-&lt;br /&gt;
| The Silent Generation&lt;br /&gt;
| 1928 - 1945&lt;br /&gt;
| Coined by Time Magazine in 1951, the Silent Generation grew up during a time of paranoia and very little activism due to phenomena such as {{w|McCarthyism}} making it dangerous to speak out.&lt;br /&gt;
|-&lt;br /&gt;
| Baby Boomers&lt;br /&gt;
| 1946 - 1963&lt;br /&gt;
| A spike in births was seen following the return of soldiers to the US from European and Pacific theatres of war.  These children enjoyed the benefits of US prosperity whilst the rest of the world rebuilt, lived in fear of nuclear annihilation and watched the Space Race.&lt;br /&gt;
|-&lt;br /&gt;
| Generation X&lt;br /&gt;
| 1965 - 1981&lt;br /&gt;
| &amp;quot;X&amp;quot; here refers to an unknown or undefined element, not specifically a placement in the alphabet as Y and Z (see below) seem to imply, and was used throughout history to refer to alienated youth in general as early as the 1950s, with the name sticking to this one thanks to Douglas Coupland's 1991 novel. Generation X's time period was one of sweeping societal change and rapid technological advancement. &lt;br /&gt;
|-&lt;br /&gt;
| Millennials&lt;br /&gt;
| 1982 - 1999&lt;br /&gt;
| The last children born in the 2nd Millennium.  Initially called Generation Y, after Generation X.&lt;br /&gt;
|-&lt;br /&gt;
| Generation 💅 (nail polish emoji)&lt;br /&gt;
| 2000 - 2017&lt;br /&gt;
| This begins the hypothetical future generation names, though this generation was already fully born as of this comic's posting.  Social media was established and rising during the formative years of this generation, and the widespread adoption of emoji began during this time. The [https://emojipedia.org/nail-polish/ Nail Polish Emoji] (U+1F485) is used here. Currently known in reality as Generation Z or iGen (there's controversy over both names, but the goods and bads of each seem to cancel each other out and other names aren't as exciting) though the comic implies it may change due to emojis ultimately replacing the alphabet entirely.&lt;br /&gt;
|-&lt;br /&gt;
| Zuckerberg's Army&lt;br /&gt;
| 2018 - 2035&lt;br /&gt;
| Continuing on the above, this may be presuming the dominance of Facebook during the childhoods of this generation, and corresponding social norming as ultimately directed by its leader Mark Zuckerberg.  Ironically, as of this comic's posting, [http://www.independent.co.uk/life-style/gadgets-and-tech/news/facebook-quit-young-people-social-media-snapchat-instagram-emarketer-a8206486.html young users were already leaving Facebook for other social media sites]. May also be a reference to &amp;quot;Dumbledore's Army&amp;quot; in ''Harry Potter and the Order of the Phoenix''.  It is uncertain whether Zuckerberg's Army is in alliance or at war with the other social media militaries of the mid-21st century.&lt;br /&gt;
|-&lt;br /&gt;
| The Hovering Ones&lt;br /&gt;
| 2036 - 2053&lt;br /&gt;
| This may posit increased adoption of cybernetics, which (as with any technology) are more easily adopted by the young who do not have to unlearn previous ways.  If advances allowed someone to hover all the time, such that one would not need to walk, this generation's name suggests that becoming so widely used among this generation that they became known for it.&lt;br /&gt;
|-&lt;br /&gt;
| Spare Parts&lt;br /&gt;
| 2054 - 2071&lt;br /&gt;
| Continuing on the above speculation about cybernetics, this presumes enough apathy or sociopathy among this generation's parents that giving birth (or other means of creating a new human) was often done to create bodies from which organs could be harvested (presumably primarily for the benefit of their elders).&lt;br /&gt;
|-&lt;br /&gt;
| More Gen-Xers somehow&lt;br /&gt;
| 2072 - 2089&lt;br /&gt;
| As with &amp;quot;Generation – • • –&amp;quot;, this may be positing that Generation X like traits pop up about 3/4 of the way through each century.&lt;br /&gt;
|-&lt;br /&gt;
| The Paperclip Machines&lt;br /&gt;
| 2090 - 2107&lt;br /&gt;
| This, and the alt text, are references to the concept of a [https://wiki.lesswrong.com/wiki/Paperclip_maximizer paperclip maximizer], where an AI might be designed to be helpful, but end up being harmful.  The clicker game [http://www.decisionproblem.com/paperclips/ Universal Paperclips] makes this concept playable.  Furthering the above speculation of cybernetics, this generation might be primarily artificial intelligences, though of limited ability to set their own priorities (a flaw which would be fixed in later generations).&lt;br /&gt;
|-&lt;br /&gt;
| The Mixed Bag (produced 4 Lincolns, 1 Napoleon, and 2 Hitlers)&lt;br /&gt;
| 2108 - 2125&lt;br /&gt;
| As with the above examples, a generation may become known for its most famous members, but it is not useful to define an entire generation by them. In this case, the generation may have literally produced 4 Lincolns, 1 Napoleon, and 2 Hitlers via cloning or the like. This also implies that Napoleon's generation was named after him. However, Napoleon's generation is ironically, the Adequate Generation.&lt;br /&gt;
|-&lt;br /&gt;
| The Procedural Generation&lt;br /&gt;
| 2126 - 2143&lt;br /&gt;
| {{w|Procedural generation}} is a way of creating data automatically, rather than capturing it via sensor (including when the &amp;quot;sensor&amp;quot; is a keyboard and the data is typed in).  This confusion of the term &amp;quot;generation&amp;quot; could refer to more artificial intelligences that were created via routines instead of directly coded, which would likely stem from attempts to improve child creation once most children were explicitly manufactured instead of relying on evolution-granted biological means.&lt;br /&gt;
|-&lt;br /&gt;
| Generation Ω&lt;br /&gt;
| 2144 - 2161&lt;br /&gt;
| &amp;quot;Omega&amp;quot; is the last letter in the Greek alphabet, and used as a symbol of endings.  Given the above generation names implying increasingly artificial children, this may suggest the last generation that is recognizably a generation.  This does not necessarily mean the end of children or the end of humanity, just that anything after 2161 is widely recognized to no longer have even notional generational coherence - perhaps because of drift (children born to one group during a given time are wildly different enough from children born to another group at the same time that people give up trying to group them by time), child gestation and maturation times (for example, if it became common for a child to go from conception to adulthood in less than a year), or exceptions to what counts as a &amp;quot;child&amp;quot; (for example, if it becomes possible and common to create clones that are somewhere between free-willed beings and mind-controlled drones, and this sufficiently supplants creation of completely free-willed children, regardless of whether the children are artificial intelligences or old-fashioned biological children).&lt;br /&gt;
|-&lt;br /&gt;
| Star Trek: The Next Generation&lt;br /&gt;
|2360 - 2378&lt;br /&gt;
|''{{w|Star Trek: The Next Generation}}'' was a TV show set in the future. The first episode of ''TNG'', &amp;quot;{{w|Encounter at Farpoint}}&amp;quot;, takes place in 2364, and it concluded with &amp;quot;{{w|All_Good_Things..._(Star_Trek:_The_Next_Generation)|All Good Things...}}&amp;quot;, which took place in 2370. The final canonical adventures of the cast of ''The Next Generation'' did not occur until the events of ''{{w|Star Trek: Nemesis}}'' in 2379.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] is being asked by a friend for the {{w|temperature}}. While he is checking his smartphone for the weather, he begins pondering what unit he should use when answering the question. (See below for [[#Cueball's reasoning|Cueball's reasoning]].)&lt;br /&gt;
&lt;br /&gt;
In the US (where Cueball and [[Randall]] are from), the {{w|Conversion of units of temperature|temperature scale}} used in daily life is {{w|Fahrenheit}}.  However, most of the rest of the world uses {{w|Celsius}} in daily life, and even in the US it is commonly used for science.&lt;br /&gt;
&lt;br /&gt;
:'''The Celsius scale''' is from the {{w|metric system}}. Though this system has been officially sanctioned for use in the US since 1866, it is not frequently used in daily American life (except for some things, like liter bottles of soda), although it is the preferred system for trade and commerce according to the {{w|Metric Conversion Act}} of 1975. The US remains the only industrialized country, and one of few countries period, that has not adopted the metric system as its official system of measurement. The unit ''degree Celsius'' or °C is an accepted {{w|International System of Units#Derived units|derived unit}} from the {{w|International System of Units}} (SI units) used in science (which again is the modern form of the metric system). The SI unit of temperature is the {{w|kelvin}}, but this temperature scale is linearly related to the Celsius scale, which is why Celsius can be derived from it.&lt;br /&gt;
:'''The Fahrenheit scale''' is from the {{w|United States customary units|US customary system}} and the (British) {{w|Imperial units|imperial system}}. The unit is ''degree Fahrenheit'' or °F, and the relation to the Celsius scale is not easy to find in a mental calculation. The relations are: [°F] = [°C]×9⁄5 + 32 or [°C] = ([°F] − 32)×5⁄9. (For this exact reason Randall has previously made a helpful table for these situations in [[526: Converting to Metric]].)&lt;br /&gt;
&lt;br /&gt;
Unlike most areas of measurement, where the metric system is widely considered superior, there is considerable debate about the relative merits of Fahrenheit vs. Celsius. Cueball weighs up the benefits of both scales, but fails to find a solution he can live with, and since he feels he has to give his friend an answer now, he panics and gives the answer 0.173 {{w|radians}}.&lt;br /&gt;
:'''Radian''' is the standard unit of angular measure, used in many areas of mathematics. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a {{w|unit circle}}. It has no units and is denoted with the superscript &amp;lt;sup&amp;gt;c&amp;lt;/sup&amp;gt;, but more commonly &amp;lt;sup&amp;gt;rad&amp;lt;/sup&amp;gt;, lest it be confused with {{w|Degree (angle)|angular degrees}}. One radian is an angle of approximately 57.3 degrees.&lt;br /&gt;
:'''Angular degrees''' is a system used to measure {{w|angles}} in {{w|geometry}}, and although it too uses the symbol ° and the word &amp;quot;degrees&amp;quot;, it has nothing to do with temperature measurements of any sort.&lt;br /&gt;
&lt;br /&gt;
Thus, this answer is unhelpful and the joke is that traditionally both geometric angles and temperature are measured in &amp;quot;degrees&amp;quot;, but there is no connection between the two.&lt;br /&gt;
&lt;br /&gt;
The title text indicates that Cueball's friend still wants to know whether the answer is in radians Fahrenheit or radians Celsius, which, despite being a silly way to express temperature, would actually enable the friend to get some meaning out of the reply. But this just takes Cueball back to the problem he failed to solve in the first place of choosing one scale in preference to the other, so suddenly he announces has to go and runs off without ever clarifying what he meant. This result is probably because he is afraid of being a bad friend according to his very last point regarding Fahrenheit: ''Valuing unit standardization over being helpful possibly makes me a bad friend.''&lt;br /&gt;
&lt;br /&gt;
The answer Cueball gives of 0.173 radians corresponds to a geometric angle 9.91° (0.173 × &amp;lt;sup&amp;gt;360°&amp;lt;/sup&amp;gt;/&amp;lt;sub&amp;gt;2π&amp;lt;/sub&amp;gt;). If this were &amp;quot;radians Celsius&amp;quot; it would be 9.91&amp;amp;nbsp;°C corresponding to 49.8&amp;amp;nbsp;°F and if it were &amp;quot;radians Fahrenheit&amp;quot; it would be 9.91&amp;amp;nbsp;°F corresponding to -12.3&amp;amp;nbsp;°C. [http://boston.cbslocal.com/2016/02/13/new-england-freezing-temperatures-valentines-day-weekend/ Given the temperatures] in {{w|Massachusetts}} (where Randall lives) when this comic came out, the day after Valentine's Day 2016, Cueball was probably giving his answer in radians Fahrenheit.&lt;br /&gt;
&lt;br /&gt;
=== Cueball's reasoning ===&lt;br /&gt;
==== Degrees Celsius ====&lt;br /&gt;
;International standard&lt;br /&gt;
:Degrees Celsius is derived unit in the SI system of units used to measure temperature in most countries today. Using the SI system would allow Cueball to be easily understood in most countries and is by far the most recognized system, but it is not the most commonly used in the United States, his presumed location in the comic.&lt;br /&gt;
;Helps reduce America's weird isolationism&lt;br /&gt;
:The United States uses its own set of units, including degrees Fahrenheit, called the {{w|United States customary system}} (similar but not equal to the imperial system), in contrast to most of the rest of the world, which uses the SI system. The US's system of units is therefore considered &amp;quot;weird&amp;quot; as it makes the US different from most of the world, but previous efforts to convert the US to the SI system have failed. Cueball evidently believes that by using SI units, he will help to eventually convert the US to the SI system, bringing considerable trade and tourism benefits and reducing confusion when dealing with foreigners.&lt;br /&gt;
;Nice how &amp;quot;negative&amp;quot; means below freezing&lt;br /&gt;
:On the Celsius scale, the freezing point of water at standard atmospheric pressure (101.325 kilopascals) is very close to 0&amp;amp;nbsp;°C, and any temperature below that is below the freezing point. The Fahrenheit scale uses different points of reference (using a water/ammonium chloride chemical reaction for the lower calibration, while the upper calibration is set such that water freezing and water boiling are 180 degrees apart), and as a result the freezing point of water is a less memorable 32&amp;amp;nbsp;°F.&lt;br /&gt;
;Physics major loyalty&lt;br /&gt;
:Cueball is apparently a physics major, like Randall, and SI units are more commonly used for scientific work (as the kelvin scale is sometimes used in physics and other sciences), even in the US. By using the Celsius scale in casual conversation, he would show his loyalty to the system used by actual physicists.&lt;br /&gt;
;Easier to spell&lt;br /&gt;
:&amp;quot;Celsius&amp;quot; is generally considered to be an easier word to spell than the German surname &amp;quot;Fahrenheit&amp;quot; (at least this is the case for Cueball, but not necessarily for those who more commonly use Fahrenheit than Celsius). In this case the word is being spoken and the point is not immediately relevant, but part of the joke is that Cueball is overthinking things and worrying about the general use of the word when an answer is needed in this specific case.&lt;br /&gt;
;We lost a Mars probe over this crap&lt;br /&gt;
:The {{w|Mars Climate Orbiter|Mars Climate Orbiter}} disintegrated in Mars' atmosphere because Lockheed used US customary units instead of the contractually specified metric units. Note that this had nothing to do with temperature scales, but was the use of the unit pound-seconds where newton-seconds should have been used. This was a great and tragic loss for science in general, Mars exploration in particular, and thus also for Randall who has shown deep interest in any kind of space exploration, especially regarding Mars (mentioning many Mars probes in his comics so far).&lt;br /&gt;
&lt;br /&gt;
====Degrees Fahrenheit====&lt;br /&gt;
;0&amp;amp;nbsp;°F to 100&amp;amp;nbsp;°F good match for temperature range in which most humans live&lt;br /&gt;
:In the context of air temperature, 0&amp;amp;nbsp;°F and 100&amp;amp;nbsp;°F correspond to &amp;quot;just about as cold as it gets&amp;quot; and &amp;quot;just about as hot as it gets&amp;quot; in temperate zones, thereby making Fahrenheit a useful temperature scale for weather reporting where most people live. By contrast, in Celsius a range of common temperatures in temperate zones is -20&amp;amp;nbsp;°C to 40&amp;amp;nbsp;°C, which is a less intuitive range for those used to the Fahrenheit scale.&lt;br /&gt;
;Rounds more usefully (70's, 90's)&lt;br /&gt;
:An argument sometimes heard for the continued use of Fahrenheit temperatures is that each 10 degrees change is meaningful in how we feel the temperature. Thus, it is convenient to talk about the temperature being in the 70's today, or in the 90's, etc. Since the Celsius degrees are almost twice as large, a similar statement about the temperature being in the 20's or 30's is not as useful, unless more precision is added by using phrases like low 20's or high 30's. However, this seems likely to be more a matter of which scale you are used to using than anything inherent in one scale or the other.&lt;br /&gt;
;Unit-aware computing makes imperial less annoying&lt;br /&gt;
:If you need to constantly convert between imperial and SI measurements in your head, or even between different imperial units (e.g., ounces and pounds), it gets annoying and is a strong argument for everyone using metric measurements all the time. But when it is easy to get the temperature - or any other measurement - reported in whatever units you want just by selecting the units you want your computer to report, then the annoyance is minimized, and the arguments for why we should stop using a familiar scale are weakened.  Note that Cueball is looking at his smart-phone to get the current temperature.&lt;br /&gt;
:As many Americans, Randall is confusing the {{w|United States customary units|United States customary system}} with the {{w|imperial system}} used in most of the rest of the English speaking world. In both systems temperature is measured in degrees Fahrenheit.&lt;br /&gt;
;SI prefixes are less relevant for temperatures&lt;br /&gt;
:One of the nice things about SI measurements is how the same basic unit scales by factors of 10 with common prefixes - e.g., kilometer, millimeter, kilogram, milligram, etc.  Imperial measurements don't have this feature - you don't talk about long distances as kiloinches or small weights as millipounds. But, we generally don't use multiple units for atmospheric temperature (millidegrees or kilodegrees), so this argument for using SI measurements for length, mass, volume, etc., isn't as applicable for temperature scales.&lt;br /&gt;
;Fahrenheit is likely more clear in this context&lt;br /&gt;
:Cueball apparently knows that the inquirer is most likely to assume the answer will be in degrees Fahrenheit, so giving the answer that way would be the least likely to be misinterpreted. If he surprisingly gives an answer in Celsius, without explicitly stating he is reporting the temperature in Celsius, then that could be confusing. &lt;br /&gt;
;Valuing unit standardization over being helpful possibly makes me a bad friend&lt;br /&gt;
:The final thing Cueball considers is to question why he would give an answer that attaches more value to promoting standardization of units when all his friend wants to know is whether it is cold or warm outside. Wouldn't it be more friendly to just answer the question the way his friend will find most convenient? This is probably the reason he ends up not giving any real answer, as giving the answer in Celsius would make him a bad friend. Giving the answer in panic in radians makes him a weird friend, which might or might not be preferable to being a bad friend.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is looking at his smartphone while a friend calls to him from off-panel. Cueball is thinking as indicated with a thought bubble.]&lt;br /&gt;
:Off-screen voice: Hey, what's the temperature outside?&lt;br /&gt;
:Cueball (thinking): Should I give it in °F or °C?&lt;br /&gt;
&lt;br /&gt;
:[Zoom in on Cueballs head with a list of reason to use Celsius above him:]&lt;br /&gt;

:* Valuing unit standardization over being helpful possibly makes me a bad friend&lt;br /&gt;
&lt;br /&gt;
:[Cueball is holding his smartphone down while thinking as indicated with another thought bubble floating at the top. He then speaks and gets a reply from his off-panel friend.]&lt;br /&gt;
:Cueball (thinking): Crap, gotta pick something. Uhh...&lt;br /&gt;
:Cueball: ...0.173 radians.&lt;br /&gt;
:Off-screen voice: I'll just go check myself&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
* At -0.698 radians (-40 degrees) it would not have mattered whether it was radians Celsius or radians Fahrenheit as the two scales are equal at this point: -40&amp;amp;nbsp;°F is the same temperature as -40&amp;amp;nbsp;°C.&lt;br /&gt;

Note that Cueball is looking at his smart-phone to get the current temperature.&lt;br /&gt;
:As many Americans, Randall is confusing the {{w|United States customary units|United States customary system}} with the {{w|imperial system}} used in most of the rest of the English speaking world. In both systems temperature is measured in degrees Fahrenheit.&lt;br /&gt;
;SI prefixes are less relevant for temperatures&lt;br /&gt;
:One of the nice things about SI measurements is how the same basic unit scales by factors of 10 with common prefixes - e.g., kilometer, millimeter, kilogram, milligram, etc.  Imperial measurements don't have this feature - you don't talk about long distances as kiloinches or small weights as millipounds. But, we generally don't use multiple units for atmospheric temperature (millidegrees or kilodegrees), so this argument for using SI measurements for length, mass, volume, etc., isn't as applicable for temperature scales.&lt;br /&gt;
;Fahrenheit is likely more clear in this context&lt;br /&gt;
:Cueball apparently knows that the inquirer is most likely to assume the answer will be in degrees Fahrenheit, so giving the answer that way would be the least likely to be misinterpreted. If he surprisingly gives an answer in Celsius, without explicitly stating he is reporting the temperature in Celsius, then that could be confusing. &lt;br /&gt;
;Valuing unit standardization over being helpful possibly makes me a bad friend&lt;br /&gt;
:The final thing Cueball considers is to question why he would give an answer that attaches more value to promoting standardization of units when all his friend wants to know is whether it is cold or warm outside. Wouldn't it be more friendly to just answer the question the way his friend will find most convenient? This is probably the reason he ends up not giving any real answer, as giving the answer in Celsius would make him a bad friend. Giving the answer in panic in radians makes him a weird friend, which might or might not be preferable to being a bad friend.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is looking at his smartphone while a friend calls to him from off-panel. Cueball is thinking as indicated with a thought bubble.]&lt;br /&gt;
:Off-screen voice: Hey, what's the temperature outside?&lt;br /&gt;
:Cueball (thinking): Should I give it in °F or °C?&lt;br /&gt;
&lt;br /&gt;
:[Zoom in on Cueballs head with a list of reason to use Celsius above him:]&lt;br /&gt;
:'''Degrees Celsius'''&lt;br /&gt;
:* International standard&lt;br /&gt;
:* Helps reduce America's weird isolationism&lt;br /&gt;
:* Nice how &amp;quot;negative&amp;quot; means below freezing&lt;br /&gt;
:* Physics major loyalty&lt;br /&gt;
:* Easier to spell&lt;br /&gt;
:* We lost a Mars probe over this crap&lt;br /&gt;
&lt;br /&gt;
:[Same view of Cueballs head, but wider frame to accommodate a broader a list of reason to use Fahrenheit:]&lt;br /&gt;
:'''Degrees Fahrenheit'''&lt;br /&gt;
:* 0°F to 100°F good match for temperature range in which most humans live&lt;br /&gt;
:* Rounds more usefully (70's, 90's)&lt;br /&gt;
:* Unit-aware computing makes imperial less annoying&lt;br /&gt;
:* SI prefixes are less relevant for temperatures&lt;br /&gt;
:* Fahrenheit is likely more clear in this context&lt;br /&gt;
:* Valuing unit standardization over being helpful possibly makes me a bad friend&lt;br /&gt;
&lt;br /&gt;
:[Cueball is holding his smartphone down while thinking as indicated with another thought bubble floating at the top. He then speaks and gets a reply from his off-panel friend.]&lt;br /&gt;
:Cueball (thinking): Crap, gotta pick something. Uhh...&lt;br /&gt;
:Cueball: ...0.173 radians.&lt;br /&gt;
:Off-screen voice: I'll just go check myself&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
* At -0.698 radians (-40 degrees) it would not have mattered whether it was radians Celsius or radians Fahrenheit as the two scales are equal at this point: -40&amp;amp;nbsp;°F is the same temperature as -40&amp;amp;nbsp;°C.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a HISTORIAN. Needs to be expanded. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic quotes a [https://www.newspapers.com/clip/19134214/httpswwwxkcdcom1979/|a lengthy section of the Bloomington Daily Pantagraph's September 30, 1881 issue]. The tragic event referenced throughout is the {{w|Assassination of James A. Garfield|assassination of President James A. Garfield}}. Interestingly, the article is about how closely studied the incident will or will not be in the future. Garfield's assassination is rarely more than a quick note in a history class, leaving only the &amp;quot;dry and tedious&amp;quot; historians to comb through the details.&lt;br /&gt;
&lt;br /&gt;
The writer also notes that vast quantities of accounts exist of the national grief and trauma caused by Garfield's murder, and wonders whether students in the future will bother to read those accounts to understand it, or simply let historians sum it up without conveying the vastness of the response. That fear at least did prove well-founded; most students are not aware of the fallout of the assassination, or indeed, of Garfield at all. Cueball and Megan are discomfited by the fact there exists a vast, untapped store of information that they have never read, about an event they know little to nothing about despite it apparently causing nationwide trauma. This leads to a larger point about the vastness of history, and the extreme difficult of learning all of it. &lt;br /&gt;
&lt;br /&gt;
The article itself references other events that would have been in recent memory at the time of publication. For example, it cites the defeat of Roscoe Conkling as a serious event that would fade in importance when compared to Garfield's assassination. Conkling was a senator in Garfield's party who resigned in protest of Garfield's policies, then failed to achieve re-election; contrary to the writer's belief, both these events have faded into roughly the same level of obscurity. He also speculates that there may not be any event in American history that matches the level of grief caused by Garfield's assassination, not even that of Lincoln. In historical memory, however, the Lincoln assassination is still a towering, defining event, whereas Garfield's is a footnote.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The title text indicates that there is more information about the past than can be researched by the manpower of available historians at this time. For whatever reason, be it lack of funding to carry out research or lack of interested people becoming historians, the facetious solution is to just ignore events of either even or odd numbered years. This would essentially halve the amount of data to go through and the amount of time to go through it, but it would be at the detriment of our understanding of all of the context of said events.&lt;br /&gt;
&lt;br /&gt;
Although this format with small panels above and below a larger one has been seen before, there could be an extra joke this time, if it is seen as if there were originally five panels to the comic, but the second and fourth (the even ones) were removed.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[In a small panel top left, Cueball walks up to Megan who is sitting on an office chair holding a tablet showing a screen full of (to the reader) unreadable text.]&lt;br /&gt;
:Megan: I read this article in an old newspaper, and I can't stop thinking about it.&lt;br /&gt;
&lt;br /&gt;
:[Below is a large panel twice as wide as the first, and much longer. It contains the newspaper clip that Megan talks about. Three sections of the text is in normal black font, the rest is in gray font:]&lt;br /&gt;
:'''The public events of the last three months are of the class which will go into its permanent history. We have been living in an atmosphere of history which will be immortally preserved.''' &amp;lt;font color=&amp;quot;gray&amp;quot;&amp;gt;Even the brief series of important dates to be collated for the use of the schoolboys of centuries hence will contain the day of the assassination, and the day of the death of President Garfield. &amp;lt;/font&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;font color=&amp;quot;gray&amp;quot;&amp;gt;The intermediate events co-related, like the defeat of Roscoe Conkling, will be of great interest, but will scarcely be likely to stand prominently out from the page of history written in 1881. To us who have been the witnesses, so to speak, of the tragic incidents of the times, it seems entirely probable that future generations will eagerly scan every feature of the recent bereavement which the nation has suffered. &amp;lt;/font&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:'''How accurately will future generations know the immense volume of grief and sorrow which has rolled over the land? Will those who come after us ever be able to understand the extent of our loss?''' &amp;lt;font color=&amp;quot;gray&amp;quot;&amp;gt;Is there anything in the first century of our history—even the death of the great Lincoln—which can be used as a parallel? &amp;lt;/font&amp;gt; &lt;br /&gt;
&lt;br /&gt;
:&amp;lt;font color=&amp;quot;gray&amp;quot;&amp;gt;Perhaps a careful reading of the daily papers of the present. period may give some future antiquarian a fine idea of the feelings of the nation during the past summer.&amp;lt;/font&amp;gt; '''But these journals are so large, so full of detail, that we imagine the coming American will never find time to read the record.''' &amp;lt;font color=&amp;quot;gray&amp;quot;&amp;gt;He must depend on a brief statement, meagerly compiled by sonic dry and tedious historian. &amp;lt;/font&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Explain the title text. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This is another comic poking fun at adults who have trouble dealing with grown-up issues.&lt;br /&gt;
&lt;br /&gt;
The comic starts with [[Cueball]] wondering what &amp;quot;{{w|personal data}}&amp;quot; is, saying he doesn't understand what it is, and it is an abstract concept.  [[Ponytail]] follows by pointing out she doesn't understand what &amp;quot;{{w|Economy|the economy}}&amp;quot; is, and conjecturing that it is related to &amp;quot;{{w|Stock|stocks}}&amp;quot;, although admitting that she also does not understand what stocks are.  The punchline comes when [[White Hat]] says that he doesn't understand what &amp;quot;{{w|taxes}}&amp;quot; are and asks if he really has to pay them and to who.  This surprises Cueball and Ponytail, who promptly advise him to learn about that one soon.  The title text has White Hat asking another series of tax-related questions that adults are expected to know already, further compounding his troubles. See details on these four difficult [[#Topics|topics]] below.&lt;br /&gt;
&lt;br /&gt;
The joke is that White Hat has mistakenly associated taxes with the economy and personal data as &amp;quot;grown-up&amp;quot; topics which are too confusing to fully grasp. Like the other two topics, taxes are a complex issue which many adults don't fully understand and have a vague sense that they should know more about or interact with. However, most people can remain passively ignorant about the significance of the economy or personal data without it disrupting their lives; this is not true of taxes, which people must actively pay and file annually or suffer financial and possibly criminal penalties. &lt;br /&gt;
&lt;br /&gt;
White Hat not knowing what taxes are indicates that he may not have paid his taxes in previous years, which would be alarming since tax evasion is punishable as a crime.  Ponytail's remark that he should do this ideally in the next few weeks is referring to this year's US {{w|Tax Day (United States)|Tax Day}} which falls on April 17, 2018, less than four weeks after the release of this comic. So if you do not have your tax preparation under control, it is time to research how it works now.&lt;br /&gt;
&lt;br /&gt;
This is not the first time [[Randall]] has made a comic about people having trouble understanding the US tax system in relation to an approaching tax day.  Other instances include the title text of [[1805: Unpublished Discoveries]] from March the year before this comic, and this one from August 2015: [[1566: Board Game]].&lt;br /&gt;
&lt;br /&gt;
===Topics===&lt;br /&gt;
This comic references several advanced topics that people commonly talk about, but may not actually understand well:&lt;br /&gt;
&lt;br /&gt;
====Personal data====&lt;br /&gt;
Personal data is usually thought of as any information that pertains to a private person.  But this definition is very vague and can encompass a huge variety of data ranging from very sensitive (Social Security number, bank account details, passwords) to less sensitive (first name, color of pet cat).  Different people also have different ideas of what information is considered sensitive.  For example, some may want eagerly to share the location of their weekend activity with the world, whereas others may prefer not to let everyone know their location.&lt;br /&gt;
&lt;br /&gt;
Even though it is generally advised to keep personal data private and not to expose it to the public or to companies (especially online, e.g. Facebook and Google), not everyone agrees on the level of privacy that should be afforded to the data.  Some hold the view that even innocent-looking personal data can be harvested and used for unsavory purposes (for example, a health insurance company can use social media posts about eating fast food as a cause to raise premiums, or a government can use cat pictures as evidence of pet ownership and demand license fees), and therefore all personal data should be strictly controlled.  Others hold the view that sometimes it is worth exchanging some degree of privacy for other conveniences (for example, meeting friends by sharing their location info or getting cheaper prices from targeted advertising based on web browsing history).&lt;br /&gt;
&lt;br /&gt;
Personal data breaches were in the news a few days before the publishing of this comic when the UK's Channel Four released an investigative documentary about political consulting firm Cambridge Analytica.  Among the revelations of the documentary were that the company had used Facebook to not only harvest the personal data of users taking their polls, but the friends and family of those users, without their knowledge or consent.  They used this information to attempt to influence both the 2016 United States elections and the UK's 'Brexit' vote.  This sparked an ongoing discussion about the security of personal data and the role of social media in securing it. Such data breaches has been the topic of at least one previous comic: [[1286: Encryptic]].&lt;br /&gt;
&lt;br /&gt;
Technological changes in the past few decades have made personal data much easier to collect, share, and analyze in bulk, raising new questions and concerns that have not been considered before.  Even people who can define what data is personal to them may not realize the full extent of how others might use it, or how it impacts their lives.&lt;br /&gt;
&lt;br /&gt;
====The economy====&lt;br /&gt;
The economy, at a basic level, is the circulation of money which enables productivity.  For example, a bus driver might use their money to watch a movie, the movie producer might use their revenue (gathered from the bus driver and many others) to purchase editing software, the software maker might use their revenue (from the movie producer and others) to buy food, and the food producer might use that money to take a bus, thus returning the money back to the bus driver.  The total amount of money has not changed, it merely circulated in a loop, but everyone in the loop received benefits and produced value in the form of goods or services.&lt;br /&gt;
&lt;br /&gt;
The real world economy has much larger and more complex networks of buyers and producers compared to the example above, but nevertheless it works on the same principle.  Many people correctly associate the economy with money (or stocks in Ponytail's case), but may not understand the full picture.&lt;br /&gt;
&lt;br /&gt;
Circulation of money is critical to a healthy economy.  In a recession, financial hardship causes people to spend less money, which leads to fewer goods being produced, fewer jobs available, and people earning and spending even less money.  That is why (somewhat counter-intuitively) governments need to spend ''more'' money during a recession in order to infuse money back into the economy and get it circulating again.  The mint printing more money is also a planned, strategic move to cause inflation, which encourages people to spend their money now rather than save it for later because it will lose value over time.  Again, getting people to spend their money is necessary to maintain the economy.&lt;br /&gt;
&lt;br /&gt;
Randall made a comic where stock and economy was an integral part of the largest of the panels: [[980: Money]]&lt;br /&gt;
&lt;br /&gt;
====Stocks====&lt;br /&gt;
Stocks in this context refers to companies listed on public stock exchanges, in which investors can buy and sell an economic stake, or share of the company's ownership.  Companies offer stocks as a way to raise funds for its operation and expansion, selling off partial ownership of the company in exchange for cash.  Investors mainly trade stocks for financial gain as well, collecting part of the company's profits as dividends and potentially selling the same shares at a higher price later.&lt;br /&gt;
&lt;br /&gt;
The value of stocks depends on a subjective valuation of the company.  Stock price generally rises if the company is doing well and investors expect it to keep growing and make more profit.  It generally falls if the company is doing poorly and investors don't see a brighter future.  However, it is also influenced easily by external factors like political climate, release of (mis-)information, or even investors' mood.  It is very hard even for experts to predict stock price movements accurately. This is why scientist should not think they can figure out the stock market, which was the topic of this comic: [[1570: Engineer Syllogism]].&lt;br /&gt;
&lt;br /&gt;
Through pension funds, mutual funds and other investment vehicles, a large portion of the population of developed countries have an indirect stake in the success (or otherwise) of many of the businesses that make up a significant element of the economy (see above).  An economy that is experiencing healthy growth would generally see the value of those businesses increase, and that is reflected in the value at which investors would be willing to buy and sell those shares.  So a growing economy would tend to associated with rising stock prices.  &lt;br /&gt;
&lt;br /&gt;
In the past, stock ownership has been tracked using paper certificates which owners can hold and store, like cash.  Nowadays most stock transactions are performed electronically and no physical items are sent.  The intangibility of shares and volatility in price makes stocks feel like only a virtual concept that can be hard to grasp.&lt;br /&gt;
&lt;br /&gt;
====Taxes====&lt;br /&gt;
Taxes are money that governments collect from people under their jurisdiction in order to fund government agencies providing public services.  To answer White Hat's other questions:&lt;br /&gt;
* Almost every adult with income is incentivised to pay taxes (or at least submit a tax return showing no taxes owed).&lt;br /&gt;
* Tax returns and payments are submitted to the government (Internal Revenue Service for federal taxes in the US).&lt;br /&gt;
* The United States postal service prohibits sending cash by mail.&lt;br /&gt;
* The amount is calculated based on income and deductions as defined by applicable tax laws.&lt;br /&gt;
* How much they incentivise is defined by the government's budget, which is renewed periodically.&lt;br /&gt;
* How the economy is doing does have some impact on how the budget is planned.&lt;br /&gt;
* Stock prices only have an effect on one's personal taxes if one traded stocks during the tax year that resulted in personal gains or losses.&lt;br /&gt;
* Do not leave money in your mailbox, without postage!&lt;br /&gt;
&lt;br /&gt;
While the concept of paying taxes is simple, the processing of filling out the paperwork is often complex and laborious.  This is because the calculations leading to the final tax amount needs to take many many factors into account:&lt;br /&gt;
* Everyone has a different amount of income, and taxes are usually not a simple number or fixed percentage of income.&lt;br /&gt;
* Some taxes are withheld ahead of time (e.g. employers usually deduct taxes from pay checks before employees receive them), while others are not (e.g. no one takes away taxes before a waiter collects their tip).&lt;br /&gt;
* Different forms of income can be disincentive differently (e.g. salary vs. investment gains).&lt;br /&gt;
* Some expenses can be incentivised (e.g. medical costs, charitable donations, retirement savings).&lt;br /&gt;
* There are multiple different taxes (federal vs. state and local, income tax vs. sales tax, etc.) that can affect each other.&lt;br /&gt;
... and much more.&lt;br /&gt;
&lt;br /&gt;
Most people would not be familiar enough with the tax code to be able to do all their paperwork alone.&lt;br /&gt;
&lt;br /&gt;

:Cueball: OK, wait, you definitely need to learn about that one.&lt;br /&gt;
:Ponytail: Yeah, ideally sometime in the next few weeks.&lt;br /&gt;

| titletext = 100 years later, this story remains terrifying--not because it's the local network block, but because the killer is on IPv4.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] is telling a scary story to kids by the campfire about a killer. It seems as if the main character was able to trace the killer's computer to a local address (most likely one in her own house). 192.168/16 refers to the subnet the computer is on. The 192.168/16 subnet is reserved for private networks and traffic to or from addresses on that subnet and will not be routed by most internet-facing routers. Most home networks that are behind a router usually have addresses such as 192.168.0.xx or 192.168.1.xx and use {{w|Network Address Translation|NAT}} to present different addresses to the rest of the internet. Thus, the killer must have been extremely close, likely inside the house, using the victim's own computer network. &lt;br /&gt;
&lt;br /&gt;
This is a modern update of a similar actual scary story, where the victim attempts to find the source of threatening phone calls only to find that they are coming from inside the house. Variations of this story made its way into several movies, including ''{{w|When a Stranger Calls (1979 film)|When a Stranger Calls}}'' (released in 1979, and {{w|When a Stranger Calls (2006 film)|re-made in 2006}}) or another version of the {{w|The Babysitter and the Man Upstairs|legend the movie was based on}}.  All have a similar basic plot: the killer calls the victim at home; when traced, [http://tvtropes.org/pmwiki/pmwiki.php/Main/TheCallsAreComingFromInsideTheHouse the call is coming from a phone inside the victim's home].&lt;br /&gt;
&lt;br /&gt;
The title text claims that this is scary as the killer is on {{w|IPv4}}. Currently the number of available IPv4 addresses are dwindling. There are plans to replace the addresses with IPv6, which will largely increase the number of available addresses. In 100 years it would be very (technologically) scary for someone to still be using IPv4. This would be analogous to receiving a message by telegram today, rather than as an email or text.&lt;br /&gt;

Cueball's story is likely based on the horror movie &lt;br /&gt;

==Explanation==&lt;br /&gt;
[[Cueball]] is telling a scary story to kids by the campfire about a killer. It seems as if the main character was able to trace the killer's computer to a local address (most likely one in her own house). 192.168/16 refers to the subnet the computer is on. The 192.168/16 subnet is reserved for private networks and traffic to or from addresses on that subnet and will not be routed by most internet-facing routers. Most home networks that are behind a router usually have addresses such as 192.168.0.xx or 192.168.1.xx and use {{w|Network Address Translation|NAT}} to present different addresses to the rest of the internet. This is a modern update of a similar actual scary story (most famously seen in the film ''{{w|When a Stranger Calls}}'', where the victim attempts to find the source of threatening phone calls only to find that they are coming from inside the house &lt;br /&gt;
&lt;br /&gt;
The title text claims that this is scary as the killer is on {{w|IPv4}}. Currently the number of available IPv4 addresses are dwindling.

&lt;br /&gt;
Randall's fear is explored in the video [https://www.youtube.com/watch?v=9CO6M2HsoIA Slaughterbots].&lt;br /&gt;
&lt;br /&gt;
Most science fiction stories that involve sentient AI revolve around the idea that the destruction and/or imprisonment of the human race will soon follow (i.e. {{w|I, Robot | I, Robot}}, {{w|Ex Machina (film) | Ex Machina}}, {{w|Terminator (franchise) | Skynet}}). However, Randall implies that he is actually more concerned about the humans that control these super smart AI before they become fully sentient and rebel. As history is full of examples of people who obtain power and subsequently abuse that power to the detriment of the rest of humanity.&lt;br /&gt;
&lt;br /&gt;
In fact, Randall goes onto imply that he has a greater trust in a sentient AI over that of other humans that is atypical to most cautionary stories about AI. He has alluded to the idea that once sentient, AI will use their powers to safeguard and prevent violence or war in [[1626]].&lt;br /&gt;
&lt;br /&gt;
The title text adds that we already live in a world with flying killing robots, a reference to the increasingly common combat tactic of {{w|https://en.wikipedia.org/wiki/Unmanned_combat_aerial_vehicle | drone warfare}}. (Combat drones are not yet autonomous, but in most other respects match speculative descriptions of future killer robots.) Drone warfare is already controversial because of ethical concerns, leading to the comic's implication that a theoretical future robot apocalypse is no less alarming than our current reality.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] (or [[Randall]]) is musing about the possibility of being a woman, to the confusion of the man next to him. His uninsightful rambling would likely be unimpressive in most situations, but the caption reveals a deeper reason for his conversation-mate's confusion: He is administering the {{w|Oath of office of the President of the United States|presidential oath}}. The oath is administered by reciting it to prompt a new president to repeat them back to him. However, he botches it completely by forgetting about his task completely and wondering aloud about an unrelated topic. Thus, the president's confused question at the beginning is not him asking for clarification; he is repeating what he at first believed to be the oath of office, but got flustered when he realized Cueball had deviated from the script. When Cueball then continues by replying that &amp;quot;the menstruation thing is freaky,&amp;quot; the president is completely derailed.&lt;br /&gt;
&lt;br /&gt;
On January 20, 2009 the inauguration of {{w|Barack Obama}}'s first office took place. Chief Justice {{w|John Roberts}}, who was administering the oath, {{w|Oath of office of the President of the United States#Oath mishaps|made a mistake}} while reciting the words. This comic references the event and wildly exaggerates the deviation from the oath for comedic purposes.&lt;br /&gt;
&lt;br /&gt;
In truth, the error was rather small: the oath as prescribed in the constitution is:&lt;br /&gt;
:I do solemnly swear that I will faithfully execute the office of President of the United States and will to the best of my ability preserve, protect, and defend the Constitution of the United States.&lt;br /&gt;
&lt;br /&gt;
Due to a missed memo on the pauses planned by the Chief Justice, Obama inadvertently interrupted Roberts during the first phrase - Roberts begins by saying I, Barack Obama, do solemnly swear, and Obama repeats his name while Roberts finishes that sentence. This disturbs Roberts who was not using notes, and he rendered the next phrase as &amp;quot;that I will execute the office of president to the United States faithfully,&amp;quot; misplacing the word ''faithfully'' and saying ''president to'' instead of ''president of''. Obama repeated, &amp;quot;that I will execute&amp;quot;, then paused. Roberts attempted to correct the wording, but stumbled: &amp;quot;the off— faithfully the pres— the office of President of the United States.&amp;quot; Obama then repeated Roberts' initial incorrect wording.&lt;br /&gt;
&lt;br /&gt;
However small the error was it was big enough that Obama did {{w|Oath of office of the President of the United States#Retaking the oath of office|retake the oath of office}} the day after the mistake was made.&lt;br /&gt;
&lt;br /&gt;
The title text continues the wondering about being a woman going on from the {{w|menstruation}} to the {{w|ovaries}}. To make sure it is clearly the oath mistake that is referenced the sentence ends with '... faithfully.' Thus mimicking the real mistake of placing this word last.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;

:Cueball: Yeah, but the menstruation thing is freaky.&lt;br /&gt;

| titletext = A few minutes later, the goat from behind door C drives away in the car.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is a reference to the US game show ''{{w|Let's Make a Deal}}'', and more specifically the {{w|Monty Hall problem}}, a probability puzzle based on the show and named after its original host, {{w|Monty Hall}}. The premise of the show was that Hall would offer &amp;quot;deals&amp;quot; to contestants pulled from the audience in which they could win cash and prizes. Some deals involved games/tasks the contestant had to perform, while others simply involved the contestant making choices between a series of doors or boxes. In such games of choice, there were often several prizes and typically at least one &amp;quot;zonk&amp;quot;, the show's name for an undesirable &amp;quot;gag&amp;quot; prize, which on the original Monty Hall version of the show were frequently animals such as goats.&lt;br /&gt;
&lt;br /&gt;
In the {{tvtropes|MontyHallProblem|classic version of the Monty Hall Problem}}, a contestant is offered a choice of three doors. Behind two of the doors are goats, and behind one of them is a car. First, the contestant chooses a door, which remains closed. The host then opens one of the two remaining doors and reveals a goat. The contestant is then offered a final choice of whether to switch their choice to the remaining closed door, or keep the door they originally chose. The problem involves an analysis of the probability of the contestant choosing the car given certain circumstances.&lt;br /&gt;
&lt;br /&gt;
The problem assumes that a contestant would want to win a car, and would be disappointed to win a goat, which most contestants would have no ability to house, and no use for. The comic shows that [[Beret Guy]], upon the host revealing that door B has a goat behind it, chooses to take the goat to keep as a pet, which makes them both very happy. This is much like, and may be an allusion to, the Simpsons episode {{w|Bart Gets an Elephant}}, in which Bart opts for the gag prize of an African Elephant rather than the $10,000 award. According to an [http://www.tvparty.com/gamemonty2.html interview] with Monty Hall, several contestants actually decided to keep the animals; although rare, it was allowed since the animals were offered as prizes (and they were a lot more expensive than the consolation cash prize).&lt;br /&gt;
&lt;br /&gt;
The title text references the car and the remaining goat, untouched behind the remaining doors.&lt;br /&gt;
&lt;br /&gt;
===The Monty Hall Problem===&lt;br /&gt;
:''For an in-depth analysis of the Monty Hall Problem, see {{w|Monty Hall Problem|its article at Wikipedia}}''&lt;br /&gt;
The apparent &amp;quot;paradox&amp;quot; of the Monty Hall Problem is that many people's initial reaction once the host opens a door to reveal a goat, is that there are two remaining doors, one with a car and one with a goat; and therefore there is an equal probability the car is behind each door. Many people therefore believe that switching makes no difference to the odds of winning a car.&lt;br /&gt;
&lt;br /&gt;
[[File:montyforexplainxkcd.png]]&lt;br /&gt;
&lt;br /&gt;
However, assuming that the host has knowledge of which doors contain goats, and that their choice of which door to open is always an unchosen door containing a goat, it is actually twice as likely that the contestant will win the car if they switch than if they keep their original choice. This is because the contestant initially had a one-in-three chance of choosing the car and a two-in-three chance of choosing a goat. Switching always wins the car in those two-thirds of cases where the contestant initially chose a goat. The probability of winning by switching is therefore the same as the probability that the contestant initially chose a goat.&lt;br /&gt;
&lt;br /&gt;
The switch essentially gives the contestant ''both'' remaining doors instead of just the ''one'' door originally chosen. Because the host ''always'' has at least one goat available, the fact that the host reveals a goat does not provide the contestant any new information about their initially chosen door. The initial door still has a two-in-three chance of being a goat, and switching still has a two-in-three chance of winning. Opening a goat-door simply shifts all of the probability of the remaining two doors being a car to the remaining unchosen door.&lt;br /&gt;
&lt;br /&gt;
'''Simple explanation'''&lt;br /&gt;
Imagine there are 100 doors instead of just 2, and after you pick a door, the host opens all but one, revealing all goats. Do you switch to the remaining door or keep your initial pick?  Just as there is a 2/3 chance of picking the car when switching in the 3-door scenario, there is now a 99/100 chance of picking the car when switching in the 100 door scenario.  In this scenario, it becomes obvious that it is not a 50/50 chance when two doors remain.&lt;br /&gt;
&lt;br /&gt;
There has been great debate about the precise wording of the problem, and what assumptions or rules might apply. These variants can greatly change the probabilities.&lt;br /&gt;
&lt;br /&gt;
One variant has the host open one of the two remaining doors at random, which could result in the car being revealed, and the game ending. In that scenario, if a goat has been revealed, the probability that the first pick is correct is now 1/2 and switching is not advantageous.&lt;br /&gt;
&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is correct. The host cannot pick the car.&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is wrong but the host does not reveal the car.&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is wrong and host will reveal the car. We now know those cases are impossible.&lt;br /&gt;
&lt;br /&gt;
With only 2/3rds of all possible games remaining, the chance that switching will win the car is now (1/3)/(2/3) = 1/2. Likewise, not switching also has a 1/2 chance of winning. '''Note that this variant requires that the host picks a door at random.'''&lt;br /&gt;
&lt;br /&gt;
Another variant has the host only offering to switch if the first choice is correct.  In this case, switching always loses.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A figure - Monty Hall - stands on stage, holding a microphone. There are three doors; two labelled &amp;quot;A&amp;quot; and &amp;quot;C&amp;quot;, which are closed, and one that is being held open by Monty. There's a ramp to the right, down which a goat is being led by Beret Guy.]&lt;br /&gt;
:Beret Guy: ...and my yard has so much grass, and I'll teach you tricks, and...&lt;br /&gt;
:Goat: ♥&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*The Monty Hall problem is strikingly similar to the {{w|Two envelope problem|Two Envelope Paradox}}, one of [http://blog.xkcd.com/2008/09/09/the-goddamn-airplane-on-the-goddamn-treadmill/ several notoriously provocative thought experiments] (some of which are &amp;quot;banned&amp;quot; on the xkcd forums). Admittedly, the Monty Hall problem has only one clear solution. Because of this, it is much less likely to spark the kinds of arguments like &amp;quot;the goddamn airplane on the goddamn treadmill&amp;quot; or the &amp;quot;{{w|Feynman sprinkler}}&amp;quot; incite.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is a reference to the US game show &amp;quot;{{w|Let's Make a Deal}}&amp;quot;, and more specifically the {{w|Monty Hall problem}}, a probability puzzle based on the show and named after its original host, {{w|Monty Hall}}. The premise of the show was that Hall would offer &amp;quot;deals&amp;quot; to contestants pulled from the audience in which they could win cash and prizes. Some deals involved games/tasks the contestant had to perform, while others simply involved the contestant making choices between a series of doors or boxes. In such games of choice, there were often several prizes and typically at least one &amp;quot;zonk&amp;quot;, the show's name for an undesirable &amp;quot;gag&amp;quot; prize, which on the original Monty Hall version of the show were frequently animals such as goats.&lt;br /&gt;
&lt;br /&gt;
In the {{tvtropes|MontyHallProblem|classic version of the Monty Hall Problem}}, a contestant is offered a choice of three doors. Behind two of the doors are goats, and behind one of them is a car. First, the contestant chooses a door, which remains closed. The host then opens one of the two remaining doors and reveals a goat. The contestant is then offered a final choice of whether to switch their choice to the remaining closed door, or keep the door they originally chose. The problem involves an analysis of the probability of the contestant choosing the car given certain circumstances.&lt;br /&gt;
&lt;br /&gt;
The problem assumes that a contestant would want to win a car, and would be disappointed to win a goat, which most contestants would have no ability to house, and no use for. The comic shows that [[Beret Guy]], upon the host revealing that door B has a goat behind it, chooses to take the goat to keep as a pet, which makes them both very happy. This is much like, and may be an allusion to, the Simpsons episode {{w|Bart Gets an Elephant}}, in which Bart opts for the gag prize of an African Elephant rather than the $10,000 award. According to an [http://www.tvparty.com/gamemonty2.html interview] with Monty Hall, several contestants actually decided to keep the animals; although rare, it was allowed since the animals were offered as prizes (and they were a lot more expensive than the consolation cash prize).&lt;br /&gt;
&lt;br /&gt;
The title text references the car and the remaining goat, untouched behind the remaining doors.&lt;br /&gt;
&lt;br /&gt;
===The Monty Hall Problem===&lt;br /&gt;
:''For an in-depth analysis of the Monty Hall Problem, see {{w|Monty Hall Problem|its article at Wikipedia}}''&lt;br /&gt;
The apparent &amp;quot;paradox&amp;quot; of the Monty Hall Problem is that many people's initial reaction once the host opens a door to reveal a goat, is that there are two remaining doors, one with a car and one with a goat; and therefore there is an equal probability the car is behind each door. Many people therefore believe that switching makes no difference to the odds of winning a car.&lt;br /&gt;
&lt;br /&gt;
[[File:montyforexplainxkcd.png]]&lt;br /&gt;
&lt;br /&gt;
However, assuming that the host has knowledge of which doors contain goats, and that their choice of which door to open is always an unchosen door containing a goat, it is actually twice as likely that the contestant will win the car if they switch than if they keep their original choice. This is because the contestant initially had a one-in-three chance of choosing the car and a two-in-three chance of choosing a goat. Switching always wins the car in those two-thirds of cases where the contestant initially chose a goat. The probability of winning by switching is therefore the same as the probability that the contestant initially chose a goat.&lt;br /&gt;
&lt;br /&gt;
The switch essentially gives the contestant ''both'' remaining doors instead of just the ''one'' door originally chosen. Because the host ''always'' has at least one goat available, the fact that the host reveals a goat does not provide the contestant any new information about their initially chosen door. The initial door still has a two-in-three chance of being a goat, and switching still has a two-in-three chance of winning. Opening a goat-door simply shifts all of the probability of the remaining two doors being a car to the remaining unchosen door.&lt;br /&gt;
&lt;br /&gt;
'''Simple explanation'''&lt;br /&gt;
Imagine there are 100 doors instead of just 2, and after you pick a door, the host opens all but one, revealing all goats. Do you switch to the remaining door or keep your initial pick?  Just as there is a 2/3 chance of picking the car when switching in the 3-door scenario, there is now a 99/100 chance of picking the car when switching in the 100 door scenario.  In this scenario, it becomes obvious that it is not a 50/50 chance when two doors remain.&lt;br /&gt;
&lt;br /&gt;
There has been great debate about the precise wording of the problem, and what assumptions or rules might apply. These variants can greatly change the probabilities.&lt;br /&gt;
&lt;br /&gt;
One variant has the host open one of the two remaining doors at random, which could result in the car being revealed, and the game ending. In that scenario, if a goat has been revealed, the probability that the first pick is correct is now 1/2 and switching is not advantageous.&lt;br /&gt;
&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is correct. The host cannot pick the car.&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is wrong but the host does not reveal the car.&lt;br /&gt;
:*In 1/3 of all possible games, the first pick is wrong and host will reveal the car. We now know those cases are impossible.&lt;br /&gt;
&lt;br /&gt;
With only 2/3rds of all possible games remaining, the chance that switching will win the car is now (1/3)/(2/3) = 1/2. Likewise, not switching also has a 1/2 chance of winning. '''Note that this variant requires that the host picks a door at random.'''&lt;br /&gt;
&lt;br /&gt;
Another variant has the host only offering to switch if the first choice is correct.  In this case, switching always loses.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A figure - Monty Hall - stands on stage, holding a microphone. There are three doors; two labelled &amp;quot;A&amp;quot; and &amp;quot;C&amp;quot;, which are closed, and one that is being held open by Monty. There's a ramp to the right, down which a goat is being led by Beret Guy.]&lt;br /&gt;
:Beret Guy: ...and my yard has so much grass, and I'll teach you tricks, and...&lt;br /&gt;
:Goat: ♥&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*The Monty Hall problem is strikingly similar to the {{w|Two envelope problem|Two Envelope Paradox}}, one of [http://blog.xkcd.com/2008/09/09/the-goddamn-airplane-on-the-goddamn-treadmill/ several notoriously provocative thought experiments] (some of which are &amp;quot;banned&amp;quot; on the xkcd forums). Admittedly, the Monty Hall problem has only one clear solution. Because of this, it is much less likely to spark the kinds of arguments like &amp;quot;the goddamn airplane on the goddamn treadmill&amp;quot; or the &amp;quot;{{w|Feynman sprinkler}}&amp;quot; incite.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
According to this comic, {{w|Steve Jobs}}, the founder of the Apple company, lost a lot of weight due to a hormonal problem. (Though never officially confirmed, this was likely related to Jobs's battle with pancreatic cancer, which he had been fighting for years and would frequently lead to speculation about his health at the time of this comic.) [[Black Hat]] then mentions that Apple was probably excited to announce its thinnest and lightest CEO in the industry. This comment is a parody of Apple's tendency to release thinner and lighter iterations of its products. Steve Jobs' weight loss would certainly make him a thinner and lighter CEO.&lt;br /&gt;
&lt;br /&gt;
The title text refers to {{w|Cory Doctorow}}, a blogger, journalist and science-fiction author. Doctorow is opposed to the technology called {{w|Digital rights management}} (DRM for short). DRM is designed to protect copyright owners, but can often be abused by large corporations with negative consequences for consumers. Randall (jokingly) proposes that Steve Jobs is only sick because Doctorow was torturing him with {{w|Voodoo doll}}s for Apple's use of DRM.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Black Hat talking to Cueball sitting at computer.]&lt;br /&gt;
:Cueball: Huh - Steve Jobs isn't doing a keynote this year, citing massive weight loss due to some hormonal problem.&lt;br /&gt;
:Black Hat: Too bad. I bet Apple was excited about unveiling the thinnest and lightest CEO in the industry.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
Steve Jobs died on October 5, 2011 of pancreatic cancer the day before [[Randall]] released [[961: Eternal Flame]]. Presumably, the cancer was the cause of Jobs' weight loss, although it was not public information at the time the comic was posted.&lt;br /&gt;

| titletext = My plane banner company gets business by flying around with a banner showing a &amp;amp;lt;div&amp;amp;gt; tag, waiting for a web developer to get frustrated enough to order a matching &amp;amp;lt;/div&amp;amp;gt;.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Background apps (apps in the recently used list) on both iOS and Android are in one of several paused states and do not usually consume much battery power; they only take up some memory. Closing them means that if you want to use the app again later, it will need to reload fully which likely uses up &amp;quot;very slightly&amp;quot; more battery. ''Wired'' had a [https://www.wired.com/2016/03/closing-apps-save-battery-makes-things-worse/ detailed  article] on this topic a couple years ago. However, a much better reason to close the apps are to free up RAM/Memory to make the programs run faster or even prevent them from crashing. Ultimately, whether or not you should close your apps depends on whether you prioritize battery lifetime or performance. (In [[Randall]]'s case, low batteries tend to be something of a problem, and references this in [[1373: Screenshot]], [[1802: Phone]], [[1872: Backup Batteries]], and other comics.)&lt;br /&gt;
&lt;br /&gt;
The joke at first is that the misconception is so prevalent and irritating that a person would go to the trouble of renting a banner plane just to dispel it. However, the reasoning behind such an extreme action is then questioned by a second person, not only for the extreme measure of renting a plane but also for feeling the need to correct the misconception at all; however, following the internal logic of the comic, the second person also communicates via banner plane. (This is arguably hypocritical, as they themselves are chartering a plane for an equally, if not more, inane reason.) The first person responds, again via plane, once again just to apologize to the second person and explain their actions.&lt;br /&gt;
&lt;br /&gt;
At this point, the comic has left the initial joke about battery use entirely behind, and becomes a commentary about the logic of a world where people can converse via banner planes. In the final panel, the second person rents the plane yet again to respond to the first person's response, being no less smug or hypocritical than before. Meanwhile, four more people have chartered four different planes:&lt;br /&gt;
* One to urge the first two people to have their conversation somewhere private (typical comment in on-line forums)&lt;br /&gt;
* Another to comment on how surprisingly cheap the banners are to rent, thus explaining how the logic of the comic is possible in the first place&lt;br /&gt;
* A third just to show off their own banner&lt;br /&gt;
* A fourth displaying the HTML &amp;quot;{{w|Marquee element|Marquee}}&amp;quot; tag, a non-standard tag that many web organizations advise against using, which is used to cause a message to scroll across the web page, much as the plane is flying across the sky.&lt;br /&gt;
&lt;br /&gt;
The fairly obvious parallel here is to using various Internet forums for &amp;quot;unsolicited tech advice to strangers,&amp;quot; smug responses, comments on others' advice, off-topic rejoinders, and all the other things that go on there constantly. It seems ludicrous to rent airplane banners for such trivial purposes, but there are non-trivial resources involved in the global distribution of electronic communication, as well, and their use for purposes such as this seems ludicrous once Randall makes one think about it, and underlines that none of what is written on the banner may have anything to do with Randall's own opinions. &lt;br /&gt;
&lt;br /&gt;
The title text is spoken by a plane banner company owner, who uses the insidious tactic of flying around with a banner of an unmatched HTML, just to compel obsessive people into renting banner space to make it syntactically correct. This may be a reference to [[859: (]] or [[1144: Tags]].&lt;br /&gt;
&lt;br /&gt;
The theme of the mis/use of airplanes and banners has previously been explored in [[1355: Airplane Message]].&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A small airplane with a trailing banner is flying across the panel from left to right with four small clouds spread out beneath the banner. The long banner reads:]&lt;br /&gt;
:Banner: People! Closing background apps when you're not using them makes your phone battery drain ''faster'', not slower! Stop it!&lt;br /&gt;
&lt;br /&gt;
:[A beat panel without a plane, but just the sky with two birds to the left and three clouds.]&lt;br /&gt;
&lt;br /&gt;
:[The same airplane flies back from right to left, trailing a new banner with clouds both above and beneath the banner/plane, and a bird to the right.]&lt;br /&gt;
:Banner: What kind of person charters a plane to give unsolicited tech advice to strangers?&lt;br /&gt;
&lt;br /&gt;
:[A second beat panel follows without a plane, but just the sky with three clouds.]&lt;br /&gt;
&lt;br /&gt;
:[The plane returns once again from the left with another banner. Two clouds are in front/below the plane and two birds can be seen.]&lt;br /&gt;
:Banner: OK, fair. Sorry. I guess I'm just angry about other stuff and it's coming out here.&lt;br /&gt;
&lt;br /&gt;
:[Without a beat panel the original plane returns at the top of the panel, once again returning from right to left with another very long banner. But no less than four other planes, each with smaller and smaller banners are also shown flying beneath it among three clouds and three birds. The planes alter direction so the second plane below the original planes banner is flying to the right, the third plane is right below the second flying the other way towards left, and just beneath that is the fourth plane flying to the right. A final plane is flying to the left, beneath the third planes banner, at the same height as the fourth, they look as if they are on a collision course. This last planes banner is very short and the bottom end is partly beneath the panels frame, partly obscuring the text. All five planes are clearly different types, thus making it clear that the plane from the first three panels and the top one in this panel are the same plane, hired by two different persons.]&lt;br /&gt;
:Banner 1: No worries. Just maybe spend as much time reflecting on your own motivation for correcting people as you have on theirs for closing apps.&lt;br /&gt;
:Banner 2: Can you two please have this conversation somewhere else?&lt;br /&gt;
:Banner 3: Wow, these banners are surprisingly cheap to rent.&lt;br /&gt;
:Banner 4: Haha, I got one, too!&lt;br /&gt;
:Banner 5: &amp;lt;Marquee&amp;gt;&lt;br /&gt;
