: I would like to as a british person to corroborate this, in the 80's my Dad visited the USA (he did go to florida) and still is complaining that the freshly boiled water wasn't poured directly onto the tea bag but was instead the tea bag and the hot water(now luke warm water) and bag was delivered separately!!! The delivery of freshly boiling water on to the bag is the major issue with microwaves, not the nucleation thing in my experience. Bear in mind I don't even actually like tea, still care enough to right this, but i'll be signing this anonymously to avoid shame being bought on my family and my family's familys.

:: I first visited the US in 1980. A friend who was with hate coffee and was horrified when he ordered tea that he got the water and the tea bag separately. When he suggested they add the water as soon as it was boiled, the wait staff thought he was joking. Many years later in Texas, a waiter asked me why I, a Brit, was drinking coffee, not tea. "You don't know how to make it," I replied.

"...to the point virtually every home has an electric tea kettle as a standard appliance". If I'm reading it correctly, this and the comic suggests we (though not I, as I'm not a tea-drinker) make tea ''in the electric kettle''. Electric tea-urns, yes, or maybe a setup like a samovar. But, generally, the kettle itself (and, so far as I'm aware, always with an electric kettle) is used to heat the water, which you then pour into the tea''pot'' into which the requisite number of tealeaves/teabags are also put to steep. (Or, for the lazy way, into the mug-with-teabag.) I wouldn't be able to use my electric kettle to (for example) make my instant mashed-potato into the actual mash, if I'd have regularly used it to mash tea. Or top up the boiling saucepan that I'd realised I'd not quite enough water in to cover the pasta/vegetables/whatever. Or to easily add nust a little more heat (with less new water) to the washing-up bowl than would be possible from the hot tap, back to as hot as possible without scalding me. – Whether intentional or not, I suspect Randall has the role of kettle and teapot mixed up, and so (without the intent to parody) has the editor who wrote the above.

:: Agree, we make tea in a mug using water from a kettle. I'd be furious if an American made tea in my kettle, how will I then make up my instant Nescafe? [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 18:28, 10 December 2024 (UTC)

I don't think the section on 'Boiling the water in a pot' refers to a teapot - I think it means boiling the water in a pot on the hob, and then making tea with it (in a pot/mug). [[Special:Contributions/172.69.195.27|172.69.195.27]] 07:53, 10 December 2024 (UTC)
:I agree, but I also think there's a language issue with the use of pot vs. pan that makes things more confusing. I think there are several types of cookware that Americans call pot and British call pan. So British would not say they boil water in a pot but rather in a saucepan (if there's no kettle available of course). [[User:Mtcv|Mtcv]] ([[User talk:Mtcv|talk]]) 09:03, 10 December 2024 (UTC)

I (as Brit) am uncommon in using an electric filter coffee machine to make tea (two bags in what is supposed to be the coffee filter). Set up, press the button and come back to a not jug of fresh tea which is not stewed. If later, the hot plate has shut off and it is cold, you can zap it in a mug in the microwave.

: As another brit, what? I do not understand the mechanics of this, please elaborate. Additionally, my understanding is that the water would be *briefly acquainted* with the tea, thus would be a poor facsimile of "tea" and would rather be closer to something the americans would attempt.

::I'm guessing the water would drip on to the teabags, then soak all the way through them and drip out into the jug, without allowing sufficient to accumulate that it would run straight out without passing fully through the bag. It's an intriguing idea. But most definitely wrong.[[Special:Contributions/172.70.85.239|172.70.85.239]] 17:15, 10 December 2024 (UTC)

You Westerners have literally no idea how to make proper, good tea! SMH [[User:TPS|TPS]] ([[User talk:TPS|talk]]) 13:00, 10 December 2024 (UTC)

As a Brit who grew up in sight of the Yorkshire Tea factory – and worked there on occasion – and having travelled very widely around the world – including in the US – I feel I'm supposed to have an opinion. However, I have ''never'' encountered the microwaving of water as mentioned here, and I would not object to it as supposedly problematic for tea-quality reasons. I'd object for reasons of common sense. What mystifies me is the idea that kettles are tea-specific. They are for heating water, not making tea. Coffee uses hot water. Pasta, rice and potatoes use hot water. Peas, carrots, cabbage, sweetcorn...

Baking bread often involves a pan of steaming water in the oven.

"But I can boil water in a pan for cooking pasta or vegetables."

Yes, but you'll be waiting a l-o-o-o-ng time. I'll heat my water in the kettle, pour it into the now-hot pan, cook my pasta, and I'll be eating before your water is boiling.

A kettle is not a tea-making item any more than a frying pan is an omelette-making item; tea is simply one of the things you can make with water from a kettle. Hot water is a basic civilised human commodity, predating recorded history. That we should live in a mechanised world, and the Consumer Nation doesn't have water-boiling appliances as standard (saying instead "I don't have a kettle because I don't drink tea") is ludicrous.

Using a microwave rather than buying a kettle is a bit like not buying a hammer for driving in nails because you've got a big pair of pliers that will do. Sure, they're heavy lumps of metal than live in your toolbag, but they're not the right thing.

The Brits, incidentally, are not tea lovers. They are prolific consumers of awful tea that actual tea lovers wouldn't use for cleaning their drains. The most enthusiastic tea enthusiasts I've ever met were from Maryland.

It's all just social ceremony in the UK. Milk first, tea first, must use a saucer, must use a pot...tea is a British religion, not a British drink.[[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 14:23, 10 December 2024 (UTC)

I wonder what the Brits would feel about repurposing a single-cup coffee maker. These days, I usually put a tea bag in a mug and place it in a Keurig machine and run it (without a K-cup, of course) to deliver the hot water. Probably the wrong temperature, but fast and easy and the result is good enough. [[User:Shamino|Shamino]] ([[User talk:Shamino|talk]]) 14:52, 10 December 2024 (UTC)

Would any British person care to evaluate my tea making practices? Boil water in electric kettle. Pour water over teabag, allow to steep, remove teabag. Add sugar and ice cubes. [[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 15:54, 10 December 2024 (UTC)
:...well, seems a fairly standard "making one mug of tea for oneself" process. It lacks a milk-adding stage (thus no arguments about whether before or after the water). Removing the teabag at that point probably means it's not going to become a Builders' Brew, which is your choicd. Sugar is ok. And... Waitwhat... ''Ice Cubes?!?'' ...can I get back to you on that? [[Special:Contributions/172.70.162.163|172.70.162.163]] 17:50, 10 December 2024 (UTC)

I can confirm (by inadvertent experiments conducted on flatmates) that they indeed do not like tea being make in the kettle. What really makes them angry though is making coffee in the teapot. It ruins the taste of the teapot forever apparently. There is also a faction that insists that a teapot should never be washed, and washing it invokes a lesser anger.[[User:Gopher|Gopher]] ([[User talk:Gopher|talk]]) 15:56, 10 December 2024 (UTC)

On rare occasions where I don't have a kettle available, I use a microwave oven to boil water for tea. But it doesn't look and taste quite the same, and often leaves an ugly foam at the surface when the tea bag is added. This phenomenon is investigated here: https://cooking.stackexchange.com/a/22264. So the British might be right... Disclaimer: I'm neither from the UK nor from the US. [[Special:Contributions/172.69.68.126|172.69.68.126]] 16:16, 10 December 2024 (UTC)

There is a [https://www.tumblr.com/elodieunderglass/669449994039853056/wizardlyghost-silverjirachi-pidoop tumblr thread] about the topic of teamaking in microwaves, kettles, etc. Funnily enough it showed up in my Instagram reels feed just a few hours before this comic was posted. I was thinking perhaps Randall saw it too and was inspired by it? Both of them have to deal with the different ways of making tea and how "absurd" or "unconventional" (etc.) they are. Even if Randall didn't have it in mind, it's certainly a funny little coincidence. [[User:Pie Guy|Pie Guy]] ([[User talk:Pie Guy|talk]]) 16:36, 10 December 2024 (UTC)

I'm guessing my occasional summertime practice of filling a gallon jar with water and lots of tea bags, setting it on the back porch in the sun for a few hours until the water turns dark brown, then putting the whole thing in the refrigerator and later drinking it over ice would be toward the more angry end of the spectrum.[[Special:Contributions/172.70.126.204|172.70.126.204]] 16:39, 10 December 2024 (UTC)Pat
:I think the "in the sun for a few hours" part might just be too incomprehensible to most of us, here in Britain. If we ''have'' a few hours of sun (and we're not abroad and deliberately sunburning ourselves on the beach/beside the pool in our week at the Costa Lotta budget-all-inclusivs holiday) then we're either fuming at our workdesks complaining about the louts stripping down to their shirtsleeves and splashing in the town-centre fountains or we're on our lunch-break and we ''are'' the louts stripping down to our shirtsleeves and splashing in the town-centre fountains. In neither case would sun-stewed tea be a priority. [[Special:Contributions/172.70.162.163|172.70.162.163]] 17:50, 10 December 2024 (UTC)

There are several comics with unmarked scales. It would be interesting if the descriptions started using pixels to point where each mark is along the line. As a rough estimate, the four points mentioned here are at X-values: 90px, 115px, 345px, and 645px, indicating that the pot method is 10% as infuriating as the chalice method - or that making tea in a pot ten times would be equally as infuriating as making it once in a chalice (at least, assuming the kettle method causes zero furons. I know of {{w|hedons and dolors}}. I guess 'furons' are a unit of fury, right? [[Special:Contributions/172.70.46.236|172.70.46.236]] 16:11, 10 December 2024 (UTC)

Interesting to see the interest in editing this. Had a quick check of the last ten comics, looking at the number of edits made in the first 14 hours (the exact time this page has been around, as of me starting the check) and in total, and extrapolated to edits/day (in the case of total edits, both just to the latest edit and right up to 'now'). Thought it'd be interesting to give you my results (assuming I tallied/etc correctly)...
*3022 - 14hr: '''61''' ('''105'''/day); Total: 61 ('''105/day...''')
*3021 - 14hr: 23 (39/day); Total: 39 (11/day -> 10/day)
*3020 - 14hr: 22 (38/day); Total: 36 (10/day -> 6/day)
*3019 - 14hr: 28 (48/day); Total: 54 (17/day -> 7/day)
*3018 - 14hr: 14 (24/day); Total: 48 (4/day -> 4/day)
*3017 - 14hr: 29 (50/day); Total: 33 (32/day -> 3/day)
*3016 - 14hr: 28 (48/day); Total: 46 (4/day -> 3/day)
*3015 - 14hr: 20 (32/day); Total: '''83''' (5/day -> 5/day)
*3014 - 14hr: 40 (69/day); Total: 66 (16/day -> 3/day)
*3013 - 14hr: 36 (61/day); Total: 68 (3/day -> 3/day)
...of course, the first 14 hours probably biases to British readers/editors, and it was too fiddly to add up ''|bytes changed per edit|'' as a more useful metric than mere number of pokes. But quite a bit of interest we already have here. More edits in fourteen hours than any other article less than fourteen (indeed, 17!) days old... ;) Seems to have really hit a mark, this subject!

I would argue that the more pessimistic interpretation of the two low-end options makes sense, rather than the more generous versions offered in the current explanation. I think the first one does literally mean making tea in the kettle, and the second one does mean boiling water in a teapot. Making tea *using* a kettle isn't anything to get mad about, it's the default practice. That should put it at the zero point of the line, but it isn't, it's to the right. On the other hand, obviously making tea *in* the kettle would incite a modest amount of rage (on the scale of zero to microwaving a mug), and it makes sense that boiling water in a teapot would incite about 50% more, as shown.

A [[wikipedia:Ufology|UFOlogist]] accuses [[Cueball]] of being unwilling to listen to his claims for extraterrestrial life. UFO stands for "unidentified flying object" but is used in common parlance to mean a spaceship carrying beings from another planet. Cueball counters by admitting he once spent an entire afternoon trying to confirm the existence of a version of [[wikipedia:Cats_(2019_film)|the 2019 film adaptation of ''Cats'']] which allegedly gave the eponymous anthropomorphic felines anatomically-correct rear ends.

The ''Cats'' movie was widely panned, in part because of the unappealing design of its CGI cat characters. On March 18, 2020, Twitter user @jackwaz claimed a friend of a friend had been hired as a VFX artist to "[https://www.avclub.com/world-unites-over-need-for-cats-producers-to-releaseth-1842396923 remove CGI buttholes]" from the digital cats, meaning that there was a version of the movie where the characters all had anatomically correct buttholes. There was a wide clamor on the internet for the release of "the butthole cut," which was never confirmed to exist.

Cueball was apparently willing to lend enough credence to such an absurd and entirely inconsequential claim to spend time researching it. The idea that he would research those claims while refusing to even entertain evidence for something as important and scientifically interesting as extraterrestrial life is implausible. The only reason why most scientists would reject such claims is a total lack of even faintly compelling evidence. As [[Cueball]] points out, if someone ever managed to present evidence of alien life that was even slightly plausible, most scientists would enthusiastically spend a great deal of time and effort trying to verify it.

The comic probably pertains to U.S. Air Force veteran and former {{w|National Geospatial-Intelligence Agency}} member [https://www.newsnationnow.com/space/ufo/lawmakers-react-to-whistleblowers-ufo-claims/ David Grusch], who is seeking whistleblower status for his claims that the U.S. government is hiding crashed alien spacecraft and corpses.[https://news.ycombinator.com/item?id=36216745] It continues a common XKCD theme of mocking dubious claims, including [[Alien Observers|UFOs]], [[Health Drink|pseudoscience]], [[The Economic Argument|paranormal phenomena]], and [[Conspiracy Theories]], which are presented without plausible or verifiable evidence.

2719: Hydrogen Isotopes

}}

==Explanation==
{{incomplete|Created by a BREAK ROOM DE BROGLIE MICROWAVE USER. Do NOT delete this tag too soon.}}

{{W|Hydrogen}} is the simplest of the chemical atoms, usually consisting of a single electron orbiting a single proton. This comic imagines other humorous fictional forms of hydrogen.

'''Hydrogen'''
This is the most common isotope of hydrogen, with one proton and one electron, shown with the electron "orbiting" the proton.

'''Deuterium'''
This is the second most common isotope of hydrogen, with one electron, and both a neutron and proton in it's nucleus. About five hundredths of the hydrogen in water on Earth is deuterium.

'''Tritium'''
This is the third most common isotope of hydrogen, with one electron, and a nucleus of one proton and two neutrons, for an atomic mass of three {{w|Dalton}}s.. It is radioactive with a half-life of about twelve years. It is quite rare.

'''Ium'''
This is not an actual isotope of hydrogen (as are the rest of them, excluding maximum strength hydrogen), and is one imagined by Randall. It consists of one electron orbiting around nothing. The name likely relates to the fact that the past two isotopes consist of a suffix and "ium". Thus, hydrogen with only and electron in it would be called ium.

'''Wheelium'''
This isotope consists of a proton, electron, and neutron orbiting around nothing. It is likely called wheelium as it is shaped similarly to a wheel.

'''Instant Hydrogen (ready in 15 minutes)'''
This isotope consists of a single neutron. The title likely refers to how neutrons will on average take fifteen minutes to decay into a proton, an electron, and a neutrino, which would then form a hydrogen atom.

'''Hydrogen (Maximum Strength)'''
This isotope consists of a proton, an electron, and at least 13 neutrons. This isotope would decay quite quickly. The title likely refers to the fact that it is filled with neutrons, and is thus "Maximum Strength".

'''Oops, all neutrons'''
This isotope consists of four neutrons, with one orbiting around a group of three. It is likely to be a joke about an error, where, the creator (of these atoms) made an atom entirely out of neutrons.

==Explanation==
{{incomplete|Created by a "2023" LASER EYE SURGEON. Do NOT delete this tag too soon.}}

{{w|New Year's glasses}} are novelty eyeglasses typically worn at New Year's Eve parties, shaped like the digits of the upcoming year. They were popularized in the late 1990s and early 2000s since the middle digits (9 and 0) had holes large enough to look through or mount lenses into.

[[Ponytail]], [[White Hat]], [[Megan]] and [[Cueball]] are at a party. The first three are wearing novelty glasses in the shape of the numerals "2023", representing the upcoming New Year. Cueball has chosen to obtain cosmetic {{w|laser eye surgery}} instead. Usually, such procedures are intended to adjust a patient's corneas to correct vision problems, as an alternative to glasses and contact lenses. Cueball has apparently had the digits 2023 etched into his eyes as an alternative to wearing novelty glasses. While {{w|scleral tattooing}} is performed for cosmetic reasons, and {{w|corneal tattooing}} for both cosmetic and vision benefits, the efficacy and safety of either process is not universally accepted. The laser procedure has damaged Cueball's vision so much that he mistakes a newcomer to the party resembling [[Hairy]] as [[Rob]]. Realizing he made a mistake, his second guess is that the new arrival is named Mike.

In the title text, an earlier conversation with his {{w|ophthalmologist}} has established Cueball's problems are due to the laser burning the digits straight onto his eyeballs, without regard to endangering his vision. This is darkly satirical because preservation of eyesight is very important to most people.{{citation needed}} Most previous depictions of Cueball have not shown him wearing glasses. Laser eye surgery was referenced along with other laser equipment in [[1681: Laser Products]].

Hairy is on the other side of Cueball from them and is only carrying some item of clothing, probably a recently removed coat.

172.69.134.161: !

There may be a "Twenty-Twenty Vision" pun (only that it's 20/23 visual accuity, which isn't as bad as this Cueball now has), but not sure it's good enough to mention... [[Special:Contributions/162.158.34.70|162.158.34.70]] 22:07, 30 December 2022 (UTC)

What's Hairy holding? [[User:Thexkcdnerd|Thexkcdnerd]] ([[User talk:Thexkcdnerd|talk]]) 03:41, 31 December 2022 (UTC)
:His jacket? As per the existing Explanation, I agree that it looks like he's just entered the party, and not yet found out where to leave his outdoor coat. Perhaps was going to ask Cueball where he could safely leave it. [[Special:Contributions/172.70.91.77|172.70.91.77]] 04:00, 31 December 2022 (UTC)

Megan is (AFAICT) carrying a spare pair of 2023 glasses. Presumably for Hairy. Possibility Megan wants everyone to have 2023 glasses but Cueball has (tyically) taken it too far. [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 08:54, 31 December 2022 (UTC)

}}

==Explanation==
People often find answers to computer problems by searching on {{w|Google}}, which attempts to guess your intended search term based on your location, language and the characters you've already typed, placing its suggestions in a drop-down box beneath the input area. If the search box is clicked on but nothing is typed, the drop-down box by default shows a list of your most recent searches.

Here we see a list of search queries, each of which suggests the author is perversely misusing or overextending some computer technology. The overall impression is of someone technically sophisticated enough to shoot themselves in the foot, and who does not learn any larger lessons despite doing so repeatedly. The title text is another possible entry in this list.

The caption implies that from Randall's perspective, every computer he uses seems to be broken; he doesn't seem to realize this is because he's the one using them, not because the computers actually start off broken. (For similar themes see also these comics: [[349: Success]], [[1084: Server Problem]], [[1316: Inexplicable]] and [[1586: Keyboard Problems]]).

([[979|Dear people from the future]], if Google directed you here because it is the most popular result for a problem you are experiencing, this is not the page you were looking for).

===List of searches===
; [https://www.google.com/search?q=Google+translate+syntax+highlighting Google translate syntax highlighting]
: {{w|Syntax highlighting}} can be used when editing {{w|source code}} to make the code more readable and easier to understand. It is not generally used for natural languages, but {{w|sentence diagram}}s of brief passages are used in language education. {{w|Google Translate}} is used to translate text from one {{w|natural language}} to another. It uses {{w|JavaScript}} <tt>mouseover()</tt> to highlight words as an aid in matching phrases in the source with their translations, but does not apply different highlighting dependent on syntax.
:Alternatively, this could imply that Randall is attempting to translate code from one programming language to another using Google Translate. Success would be unlikely, since the service is not intended for this {{Citation needed}}, and syntactically valid output might further break the computer executing it.
:Two other possible interpretations of this phrase are that Randall wants to translate the phrase "syntax highlighting" to another language, or that he wants to perform syntax highlighting on the source code for Google Translate.
; Autodetect mixed bash zsh
: {{w|Bash (Unix shell)|Bash}} and {{w|Z_shell|Zsh}} are two {{w|Command-line_interface|command line interfaces}} for {{w|Unix-like}} OSes. The way to execute commands is almost identical, making detecting a script that contains a mixed syntax nearly impossible. This was later referenced in [[2510: Modern Tools]].
; CPU temperature sensor limits
: The CPU's temperature sensors exist to tell you when your CPU is becoming dangerously overheated (normally because of a faulty fan or overclocking). Someone who searches for information about the limits of those sensors is presumably expecting to misuse their CPU. Probably also a reference to [[1172: Workflow]].
; GIF to XLS
: .GIF (Graphic Interchange Format) is a file extension used to store images and sequences of images to be displayed as an animation. .XLS is the file extension for Microsoft Excel spreadsheets. The joke is that the two file types are used for different purposes - it's quite normal for someone to want to convert between .GIF, .JPG, .PNG, .BMP files, as these are all image files; or between .XLS, .CSV, and .ODS files, as these all record tabulated information. However, for some reason Randall wants to convert an image file to a spreadsheet. (This is actually possible, because a digital image is essentially an array of color and brightness values; it just wouldn't be particularly useful for most people. [http://www.think-maths.co.uk/spreadsheet Here] is a webpage with an online converter.) Matt Parker has done a [https://www.youtube.com/watch?v=UBX2QQHlQ_I stand up routine] about converting these two file types.
:An alternate way to convert an image file, such as a .GIF file, into a text-based file like an .XLS file, is through {{w|optical character recognition}} (OCR). This is only effective if the image is a copy (i.e. a scan or reasonably clear photograph) of a document containing letters and words, and neither .GIF nor .XLS are file formats anyone would usually use in that case.
; Clock speed jumper sample rate
: A jumper is an intentional short circuit used for selecting options for an electronic circuit. They are usually used where it is not feasible to use programming (such as outputting a byte or word through a port) to alter the selection, such as before the processor even begins executing. A common example would be, on some motherboards, jumpers can be used to alter the clock speeds of various motherboard functions (such as the CPU or the front side bus). These jumpers should ordinarily be modified when the computer is off. However, this search is asking how often the motherboard checks the status of the clock speed jumpers, implying that they intend to change these jumpers while the computer is powered on, and often enough that the sample rate matters (change cpu speed several times a second, by moving jumpers on the motherboard.). That is, of course, a little silly.
; [https://www.google.com/search?q=clean+reinstall+keybinding Clean reinstall keybinding]
: This refers to keybinding, the practice of mapping (binding) a certain key to a certain function (e.g., pressing PRTSC will take a screenshot). Most keyboards do not output characters directly, but only codes for which keys have been pressed (or released). Keybindings translate the pressing of the "A" key on your keyboard into the letter "A" being sent to a program which is reading keyboard input. A "clean reinstall" of keybindings is something that would almost never be necessary - it means Randall has modified his default keybindings to such an extent that his [[1031:_s/keyboard/leopard/|leopard]] has become unusable (similar to [[1284: Improved Keyboard]]), necessitating a "clean reinstall" of the bindings. Alternatively, he might be doing clean reinstalls so often that he wants a keybinding to execute them with minimal loss of time.
; Cron job to update crontab
: {{w|Cron}} is a utility on most Unix-like OSes that allows you to schedule commands or scripts to be run periodically. These scheduled jobs are read from a ''crontab'' file. A job that updates the crontab (therefore creating new jobs, removing old ones or editing existing ones) is paramount to a {{w|job scheduler}}, and trying to use cron for such functionality could result in highly unstable functionality (although a crontab could be sensibly regenerated periodically by a set of machines from a master crontab file annotated with per-host directives). This is similar to {{w|self-modifying code}}.
; [https://www.google.com/search?q=fsck+chrome+extension fsck Chrome extension]
: This is a search for an interface to the Unix '''f'''ile'''s'''ystem che'''ck'''er {{w|fsck}} via third-party software added to Chrome. fsck is a program for checking your filesystem for corruption. Repairing a filesystem this way would be inadvisable. {{Citation needed}} This might indicate confusion about the meaning of the term "online filesystem repair", in which "online" means "while the filesystem is in use" rather than "over the Internet". Alternatively, Randall might want to repair an installation of the operating system Chromium, in a manner less drastic than the {{w|factory reset}} preferred by Google.
; Recursive font
: An idiosyncratic mix of {{w|recursion}} and the font style ''{{w|cursive}}'', referring especially to text handwritten in a flowing manner. {{w|PostScript}} (the language in which {{w|PostScript fonts|some fonts}} are written) is capable of recursion and PostScript Type 3 fonts are able to use the full language. This could create effects like fonts with complicated fractal borders and fill patterns - but the increase in processing time would contribute to seeming brokenness of the computer (or printer) rendering the font.
:A true recursive font would be a form of {{w|fractal}}s ([http://blog.matthen.com/post/5340546486/first-sketches-in-mathematica-for-a-new-font-it example]).
; Regex matching valid EBNF
: EBNF refers to {{w|Extended Backus–Naur Form}}, which is used to define {{w|formal language}}s. EBNF specifies recursive patterns that are impossible for a {{w|Regular_Expression|regular expression}} (regex) to determine whether it is valid or not. There is some irony in using regex to test the validity of something which ''defines'' the validity of things like regex.
; [https://www.google.com/search?q=Hardlinks+Turing+complete Hardlinks Turing complete]
: In some file systems, for example {{w|ext4}} and {{w|NTFS}}, a single file may be referenced in multiple places in the file system. These filenames are termed "hard links" because the operating system automatically resolves them to the actual file. "Soft" or "symbolic" links are resolved indirectly via a pathname, which may reside anywhere. A file is considered deleted when the last hard link to it is unlinked; a soft link exists independently of its target. In fact, the target need not exist, in which case this is often called a dangling symbolic link.
:{{w|Turing completeness}} is the {{w|computational complexity}} required to simulate any {{w|computable function}} (given an infinite amount of memory). Recently there have been cases where [http://beza1e1.tuxen.de/articles/accidentally_turing_complete.html unexpected mechanisms] from card games to text parsers were proved to be Turing complete. Hardlinks being Turing complete would imply that creating and deleting hardlinks alone is enough to satisfy the requirements of Turing completeness.
; Opposite of safe mode
: {{w|Safe mode}} is a diagnostic mode in many operating systems and applications which allows the user to troubleshoot problems by disabling unnecessary functionality. The "opposite of safe mode" implies a "dangerous mode" where the purpose is to allow uselessly dangerous actions (in actuality this supposed dangerous mode is the default mode). A common example is the {{w|sudo}} command in Unix-like OSes, which grants the user system-level permissions.
:It's also possible that Randall sees Safe Mode so often that he sees regular mode as an unusual and unique state and needs help navigating back to it.
; Predictive touchpad
: {{w|Predictive text}} is a feature of many smartphone keyboards that predicts the most likely word the user wishes to type, and then gives the user the option to place the full word in the sentence immediately without having to finish typing it. A {{w|touchpad}} is a computer pointing device, similar to a {{w|computer mouse}}. The idea of a "predictive touchpad" seems absurd because, as opposed to typed words, there are not a limited number of swipe combinations that are possible on a touchpad. A "predictive touchpad" implies that a computer could predict where the user was going to move the mouse or click, which in this case would seem to defeat the purpose of a user input device. {{Citation needed}}.
:Interestingly, a version of Linux had a predictive cursor option, where the cursor jumped to the nearest button (like window close) when it moved near to but didn't quite reach that button.
; Google docs from bootloader
: A {{w|bootloader}} is a very small program that is usually the very first thing to execute when a computer boots up. It is used mainly for loading the operating system into memory. Such a program by itself would not be capable of directly running something as complex as {{w|Google Docs}}.
; Hardware acceleration red channel only
: {{w|Hardware acceleration}} means that certain calculations are not performed by the computer's {{w|CPU}} but by a "specialized" processor, e.g. a {{w|GPU}} which is part of the graphics adapter. This speeds up output, especially if complex 3D calculations are required, and reduces CPU load. To use this function only on a single color channel seems pretty useless, but one may want to troubleshoot a program that displays only red when hardware acceleration is enabled.
:While graphics cards are most commonly used with three or four channels (red, green, blue, and sometimes alpha), they do support two-channel or single-channel images. An 8-bit single-channel image would use the format '[https://www.opengl.org/wiki/Image_Load_Store#Format_qualifiers R8]', which is indeed 'red channel only'. This type of image could be used to store monochrome images or non-image data.
; autoexec code posted by verified twitter users. ('''Title text''')
: The term "autoexec" refers to code that runs automatically, usually during boot, and derives from one of three boot-time files for {{w|MS-DOS}}: AUTOEXEC.BAT, CONFIG.SYS and COMMAND.COM. AUTOEXEC.BAT would typically contain commands for customizing the command prompt, loading additional drivers, and/or automatically launching a program.
:Automatically executing code from the Internet is generally a terrible idea, because it could be written by someone with malicious intent and harm your computer. The joke here is that the code would only be executed if written by someone who has been "verified" on Twitter. Twitter's verification service (at the time the comic was made) only serves to show that a user is who they claim to be, not whether anything they say (or program) can be trusted, so this would provide little protection. Usually, Twitter verification is used by celebrities so they can be distinguished from people claiming to be them. The line implies that Randall is only interested in running code posted by celebrities.
:Most code downloaded from authentic sources (such as Microsoft and official Linux distributions) is verified by a cryptographic signature from a true trusted source, authenticating the origin of the software. These may include software updates that run automatically in the background. The joke here is that the term "verified" means very different things between Twitter users and software distribution.
:Additional hilarity was added to this by circumstances in 2022 when, after Elon Musk's takeover of the site, anyone could buy a visually identical verification symbol for $8. With a number of notable spoof/fake accounts being 'verified', it was potentially an even worse idea than it was in the first place — not that all genuinely verified users could be trusted to be unimpeachable in this regard.

2717: L6 Lagrange Point

{{incomplete|Created by a LANDED LAGRANGE POINT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
In celestial mechanics, the Lagrange points are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies. Or in simpler terms, positions in space where objects sent there tend to stay put, relative to each other.

There are five traditional Lagrange points, three spaced on the same orbital path as the original object (in this case Earth), and two more colinear with the Earth and the body it orbits (the Sun). Randall claims that a sixth Lagrange point outside of Cleveland, Ohio. This is pretty obviously farcical, as this would still be part of the Earth and thus not a separate Lagrange point, and [https://tvtropes.org/pmwiki/pmwiki.php/Main/PlaceWorseThanDeath plays into Cleveland's reputation as a strange place].

==Explanation==
{{incomplete|Created by a BORED FOOD.NET DRIVER BETWEEN DELIVERIES. Do NOT delete this tag too soon.}}

This comic is poking fun at the proliferation of apps and internet services such as for [https://builtin.com/consumer-tech/food-delivery-companies food delivery] and [https://www.nerdwallet.com/article/banking/best-ways-to-send-money money transfer]. The characters are discussing which to use during an evening of tabletop gaming. The group has a running competition to see who can mention fake apps or services without being called out.

[[Cueball]] mentions three food delivery services, {{w|Grubhub}}, {{w|DoorDash}}, and Food.net, and [[Ponytail]] asks him to reimburse her using {{w|Venmo}}, {{w|PayPal}}, or Yahoo Cash. Cueball expresses skepticism about Yahoo Cash, after which Ponytail admits it's a fake service and is thus obligated to pay for Cueball's meal. (Incidentally, Yahoo does provide a money transfer service to facilitate private party gambling on {{w|fantasy sports}}, called [https://sports.yahoo.com/wallet/dailyfantasy/referafriend/ Yahoo Fantasy Wallet], but it is based on {{w|PayPal}}.) Food.net, which Cueball mentioned without being called out, is not a real service; https://food.net exists but is "not available for use," and is not related to food.

Based on Ponytail's offer, if someone is correctly called out then they apparently must pay for the player who caught them, but what happens when a player isn't caught (e.g. when Cueball mentioned Food.net) isn't clear. The rules might be similar to variants of the card game sometimes known as "{{w|Cheat (game)|Cheat}}," in which a successful bluff merely allows play to continue on until someone is caught bluffing or incorrectly accuses another player.

The title text offers a tip for winning the competition after being called out for mentioning a fake service: building a working version of it and then mentioning it again the next week.

451: Impostor

2022-12-02T09:14:17Z

172.69.134.161: /* Explanation */

{{comic
| number = 451
| date = July 18, 2008
| title = Impostor
| image = impostor.png
| titletext = If you think this is too hard on literary criticism, read the Wikipedia article on deconstruction.
}}

==Explanation==
While the comic is ostensibly about grad students, it is really [[Randall]]'s way of poking fun at the relative rigor of different fields, reminiscent of [[435: Purity]]. In the comic, [[Cueball]] attempts to pose as an expert in a given field (a [[:Category:Banned from conferences|recurring pastime]] of his) and sees how long it takes before the real experts detect his nonsense.

The first panel shows [[Cueball]] discussing an {{w|engineering}} problem with [[Ponytail]]. Ponytail is talking about an immediate practical problem involving heat dissipation. Cueball suggests 'using {{w|logarithm|logarithms}}' to solve it; logarithms are a mathematical tool used for expressing an exponential relationship as a linear one. While logarithms have many uses in engineering, they are an abstract mathematical concept, and not a method of dissipating heat, so in the context of the conversation, it makes no sense and outs Cueball as having grabbed a random word he knows engineers use and thrown it in to sound smart. With the engineer's conversation focusing on an immediate practical application, it only takes 48 seconds before he exposes himself.

The second panel shows a conversation with {{w|linguistics|linguistic}} grad students who are apparently discussing the {{w|Finno-Ugric languages|Finno-Ugric language family}} (a family of related languages that includes Hungarian, Finnish, and Estonian). Cueball asks if {{w|Klingon language|Klingon}} is included in this family. The linguists instantly recognize the meaninglessness of the statement — either because Klingon is a constructed language, designed to sound "alien" to avoid sounding like any human language (thus it cannot be part of any real linguistic family), or because "Klingon" is a recognizable pop-culture reference. Either way he has exposed himself after only 63 seconds of conversation. That all being said, the inventors of the Klingon language took the word order from the Finno-Ugric languages after research showed that the order of "predicate, subject, object" is least common in human languages, so there are at least some roots of Klingon language to analyze.

In the third panel, the humor comes from the fact that the idea of {{w|sociology}} existing to rank human beings on some arbitrary intrinsic value is not only ridiculous in a scientific context, but also politically offensive. Cueball unknowingly recreates the logic behind some of the worst crimes in human history, a problem sociologists are trained to be very aware of. However, it may be something that a less educated non-sociologist would assume could pass within the field. When he describes his unscientific and offensive approach, we see one of the sociology grad students facepalming in exasperation. Because a non-expert may be able to sound somewhat educated in sociology before making such a slip-up, it is four minutes into the conversation before he is detected.

In the final panel, he attempts to pass as an expert in {{w|literary criticism}}. This field notoriously uses a great deal of impenetrable jargon, so when Cueball makes up seemingly meaningless sentences, no one notices. It gets to the point where Cueball claims he can apply literary deconstruction to the bookshelf a book is resting on, a statement that should be utterly absurd, only for the grad students to accept it. His quip at "deconstructing the self" may also be a meta joke about the field itself failing under deconstruction... (or this sentence may be a meta-meta- example of someone applying literary criticism standards to the analysis of this specific comic). We find that rather than being caught out within minutes as in the other fields, he has now published 8 papers and 2 books. The humor comes from the fact that he has accidentally made himself into a recognized authority in the field, despite not having any idea what he was talking about. In this panel, Cueball is sitting in an armchair in the position of an expert lecturing to a student, who sits at his feet apparently absorbing his inane statement.

This implies that the field itself has published a great deal of meaningless things that only superficially look meaningful through the impenetrability of the jargon. The title text challenges the audience to take a look at {{w|Deconstruction|the Wikipedia article for literary deconstruction}} if they don't believe this criticism applies - the Wikipedia article in question is almost constantly flagged for "clean-up" on the grounds that it's a jumbled mess. An archive of the article as it was when this comic was published is available [https://en.wikipedia.org/w/index.php?title=Deconstruction&oldid=225953741 here].

[[Randall]] is again promoting his new book, ''[https://xkcd.com/what-if-2/ What If? 2]'', and starts by explaining the kind of recipient who might appreciate it, basically anyone who is into science or anything in the universe... So basically anyone.

Then he also gives both direct and humorously indirect instructions of how to obtain the book for them, the latter method making a jocular (but not completely wrong) presumption that almost any text-input widget leads to some relevant search-engine result. Also the entire comic is a link to the ''What If? 2'' page on xkcd that's included in the comic. As always, clicking anywhere on the image will take you there (including actually clicking on the link).

He also suggests some other tongue-in-cheek gift ideas for several other subtypes of gift-receiver, most of which are, in keeping with the ''What If'' ethos, somewhat dangerous or impractical. A number directly reference things previously mentioned or depicted by xkcd.

|-
! Interest !! Gift Idea !! Explanation
|-
| Engineering || The {{w|International Prototype of the Kilogram|platinum cylinder}} formerly used to define the kilogram || This is an object of historical relevance of which only six exist, making it a very expensive or illegal gift. With the {{w|2019 redefinition of the SI base units|redefinition of the SI base units}} in 2019, {{w|2019_redefinition_of_the_SI_base_units#Kilogram|the kilogram}} is now defined using only natural constants rather than a physical standard. It took some time before this last SI unit was redefined, 3 years prior to this comic's release. The old prototypes are no longer as important as they were when they were actually used to define the kilogram. But they are still historical artifacts with enormous value, even apart from the value of a kilogram of platinum (about $32 000 at time of writing).
|-
| Biology || The genomes of the scientists who headed the human genome project || The "International Human Genome Sequencing Consortium," as the {{w|Human Genome Project}} team was known, involved scientists from twenty institutions in six countries. In the US, it was initially led by DNA structure co-discoverer {{w|James Watson}} who was succeeded by {{w|Francis Collins}}. In the UK, the project was led by {{w|John Sulston}}. The teams from other countries' institutions were less prominent and performed substantially less work on the initial sequencing. James Watson's genome was sequenced in 2007. The genome of {{w|Craig Venter}}, the CEO of {{w|Celera Genomics}}, was used as the exemplar for Celera’s sequence. While the “race” between Celera and NIH was declared a tie by then-President Clinton, in actuality, Celera had some 85+% coverage while NIH was about 50%.
|-
| Physics || A beam of neutrinos delivered through the earth by the LHC || {{w|Neutrino}}s interact very weakly with other particles, to the point that they almost always pass straight through matter completely unaffected. This means that particle accelerators can send neutrinos to any other point on Earth by aiming the particle beam into the ground, and the neutrinos pass straight through the Earth. This point is referenced in the What-If article "{{what if|73|Lethal Neutrinos}}". The low interactivity of neutrinos would also mean that the recipient would be unable to perceive their gift, making this a poor present for anyone except the small proportion of physics aficionados who already have a neutrino detector on-hand.
|-
| Animals || Surprise wildlife encounter (gift-wrapped box with a bobcat inside) || This is a reference to [https://www.explainxkcd.com/wiki/index.php/Category:Bobcats xkcd's rich history of mailing boxed bobcats to people]. This gift would place the recipient in a perilous situation, and, although definitely a wildlife encounter, is not a good gift.{{Citation needed}}
|-
| Law || A vacation to that area of Idaho where you can commit crimes with impunity due to a court district boundary error || This refers to the "{{w|Zone of Death (Yellowstone)|Zone of Death}}", a 50-square-mile area of Yellowstone National Park that is in the physical boundaries of Idaho, but in the legal jurisdiction of Wyoming. Because a jury in the United States must be composed of residents of the same district ''and'' state in which the crime was committed, but no one lives in this small area of a National Park, anyone who committed a crime here could not (according to a legal theory not fully tested in the courts) receive a trial, and thus could not legally be punished for said crime in any circumstance. This is an interesting legal loophole, but going to this area does not provide any more value than hearing about it, and could scare your law-enthusiast friend.
|-
| Chemistry || A necklace of element samples whose symbols spell out the recipient's name (note: names like "Katherine" and "Brandon" may cause radiation accidents.) || Novelty necklaces are a common and innocuous gift. Using element symbols to replace letters in a name is a common gimmick (famously used in the title and credits of {{w|Breaking Bad}}). Using real samples of the given elements could be difficult, as elements can be expensive, highly reactive, or toxic. Reactivity and toxicity can be dealt with by containing them in well-sealed containers (which would also be necessary for elements that are liquid or gas at room temperature), but those elements that are radioactive could be dangerous, even if fully contained, and and some have short enough half-lives that a sample wouldn't persist long enough to be used as a gift. "Katherine" would be made from Potassium (highly reactive), Astatine (rare, '''radioactive''' and has a short half-life), Hydrogen (gaseous at room temperature, flammable), Erbium, Iodine (sublimes into a gas at room temperature), and Neon (gaseous at room temperature). "Brandon" would be made from Boron, Radium ('''radioactive'''), Neodymium, Oxygen (gaseous at room temperature), and Nitrogen (gaseous at room temperature). The problems with element samples could be partially alleviated by allowing compounds rather than pure elements, but the radioactivity would still be a problem, and neon does not form compounds and as such is always gaseous. Additionally, the letters J and Q do not appear in the periodic table symbols, while M does not appear on its own (only followed by six other characters, with "o" as the only vowel amongst them), so a name like John, Quinn or Mike would be problematic.
|-
| Puzzles || Two goats and a new car || This is a reference to the "{{w|Monty Hall problem}}", in which a game show contestant has to choose between three doors, two of which conceal goats and one of which conceals a car, and wins whatever prize is revealed. (See [[1282: Monty Hall]], for another cartoon inspired by this problem.) This gift places the recipient within a puzzle which is typically discussed hypothetically rather than happening in real life. Although many people would consider a new car a ''great'' gift, those who would appreciate a gift of goats are less common.
|-
| Technology || Cybiko® wireless handheld computer for teens (2000) || This is a direct callback to [[2699: Feature Comparison|one of the previous week's comics]], which humourously suggested that this device is a better option than most of the current popular communication technologies. While an interesting example of the history of communication technology and coming from a time when experimentation was common and standards were few, it isn't very useful now, because it is no longer supported, has a communication range of 100 meters (sending text messages via radio) and one can only use it to communicate with users of the same device. However, technology enthusiasts could find it interesting as a collectors' item, so by all means it is one of the most plausible gift ideas on this list.
|-
| Space || Webb telescope personal photoshoot || The Webb telescope belongs to NASA, the ESA and the CSA, and is currently very far from Earth. It is designed to capture distant space objects in previously unseen detail. If the photoshoot implies photographing a nearby human, it is not designed to do this, even if the difficulties of sending a human about a million miles to its location could be overcome. On the other hand, if it means photographing the recipient on the earth's surface, Webb would have to point at the warm Earth and expose its optics to the Sun, permanently crippling the telescope ([https://webb.nasa.gov/content/about/faqs/faqLite.html Which is forbidden by NASA.]) and it would not have sufficient resolution to make out the subject in any case. These circumstances make it a highly impractical gift, to all intents and purposes to the point of impossibility.

On the other hand, a gift experience of being allowed to take your own snapshot of Webb in position, perhaps with a [https://www.dailymail.co.uk/sciencetech/article-10442913/James-Webb-Space-Telescope-seen-Earth-settles-orbit.html robotic telescope], might be an attractive gift to a space enthusiast! So might a chance to use the Webb telescope to take pictures of whatever celestial objects one chooses, as time on the Webb telescope is very carefully allocated.
|-
| Literature || Stephen King's writing desk (he's still using it so you'll have to fight him) || {{w|Stephen King}} is an author lucky enough to have legendary status while still alive. The desk of an author that has died would become an object of historic significance and would likely be either kept for exhibition or auctioned by their respective estate, but as Stephen King is still alive, he would probably object to his desk being subjected to the same.
|-
| Philosophy || Out-of-control trolley || This is another gift that places the recipient in the situations that they like discussing hypothetically. The {{w|trolley problem}} is a thought experiment in which one is asked to decide between allowing a trolley to kill five people or taking an action that causes it to kill one. Presenting someone with such a hypothetical problem may or may not be not a good gift, but [https://www.youtube.com/watch?v=1sl5KJ69qiA forcing them to live through it in real life] is a terrible gift. (See [[1455: Trolley Problem]] for another cartoon inspired by this problem.)
|-
| Psychology || A nice gift with a note saying you don't expect anything in return || This is perhaps the most viable option on this list. This kind of gift giving could induce the Benjamin Franklin effect, causing the gift giver to like the recipient more. It could also be used to manipulate the recipient by increasing pressure to reciprocate. This would cause them stress, making it a bad gift, but a psychologist would hopefully understand it to be a joke. A psychologist could also think about the psychology of gift-giving and reciprocation, perhaps to their enjoyment.
|-
| (Title text) Babies or literature but not both || Baby shoes || This is a reference to the six-word story {{w|For sale: baby shoes, never worn}}, often attributed to Ernest Hemingway. Someone involved with babies, such as expecting or new parents, would find baby shoes a valuable gift for their child. Someone interested in literature would see the reference to a famous work. But someone who understands the reference and also enjoys babies might be sad, since the story implies the seller was expecting a baby but something went tragically wrong.

==Explanation==
{{incomplete|Created by a MICROBE TRYING TO LURE YOU WITH CLICKBAIT. Do NOT delete this tag too soon.}}

Many if not most scientific research papers present a {{w|hypothesis}} and the result of testing the hypothesis. Scientific papers should also have titles which describe the content of the papers. See [[2456: Types of Scientific Paper]].

[[Cueball]] is writing a research paper with a {{w|clickbait}}, {{w|puffery}}, and insufficiently descriptive title, "Check out this cool microbe we found." His colleague [[Megan]] asks him whether science is supposed to be about formulating a hypothesis and testing it. Cueball agrees, changing the title to, "Is our lab really good at finding cool microbes? Some preliminary data." However, that is still an overly promotional and insufficiently descriptive clickbait title, purporting to be a study of the authors' own competence, which would be highly unusual because of the lack of objectivity due to the authors being the subject of investigation. [[:Category:Clickbait|Clickbait]] is a recurring theme on xkcd, recently considered within science publications in [[2001: Clickbait-Corrected p-Value]]. The title of a research article describing a novel organism will often contain the author(s) proposed {{w|Linnaean taxonomy|Linnaean}} name for it, which is granted as their prerogative within certain limitations.[https://www.ncbi.nlm.nih.gov/books/NBK8808/]

{{w|Empirical research|''Empirical investigations''}} and ''{{w|analysis}} papers'' almost always state and test a hypothesis, but there are many kinds of scientific papers which usually do not, including ''{{w|literature review}}s,'' which qualitatively summarize the results of other papers; ''{{w|meta-analysis|meta-analyses}},'' which quantitatively summarize the results and quality of other work; ''observational reports'' (or ''{{w|case study|case studies}}'' — not to be confused with {{w|observational study|observational studies}}, a kind of empirical analysis), which present data and a chronicle of its collection often without analysis, testing, or interpretation; ''{{w|Conference proceeding|conference papers}},'' which present preliminary work without peer review; ''definition papers,'' which attempt to formalize terms used in divergent ways in prior work; ''{{w|Dialectic#Hegelian dialectic|syntheses}},'' which present alternative views combining multiple and often conflicting concepts; ''{{w|Comparison|comparative studies}},'' which compare and contrast a class of concepts; ''{{w|Interpretive discussion|interpretive}} papers,'' showing a different perspective on previous work; ''{{w|technical report}}s,'' which may present information on a specific procedural topic or progress and results, if any, in a field; ''opinion'' and ''editorial essays,'' which are intended to argue a point of view persuasively; ''book reviews,'' which summarize monographs or biographies; and ''grant proposals,'' which make the case for funding a project. Mathematical or logic research papers which don't involve empirical observations or uncertainty would be considered technical reports in other fields. Engineering work can be reported as an empirical investigation or a technical report. Empirical research articles which do present and test a hypothesis are usually written in [https://opentextbc.ca/researchmethods/chapter/writing-a-research-report-in-american-psychological-association-apa-style/ American Psychological Association (APA) style].

Cueball seems to want to author an observational report, but Megan would prefer an empirical investigation or analysis, perhaps because they may be more likely to be accepted by peer reviewed journals, and as such are more prestigious than mere conference papers, "letters," or "communications" as observational reports are often published. However, research articles describing the discovery of new {{w|microbe}}s in prestigious peer-reviewed journals are often published as observational reports,[https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004029][http://calamar.univ-ag.fr/mangroveSAE/articles/2022/Volland%20et%20al%202022.pdf][https://link.springer.com/article/10.1007/s10482-021-01656-x] so Megan's concerns may be unfounded; even if so, the editors of any reputable journal would almost certainly require a far more descriptive and less overtly promotional title from Cueball. The question remains whether an intial submission with a catchy clickbait title might get more prompt attention from editors and reviewers.

In the title text, the {{w|conflict of interest}} statement says that the authors hope their results are correct because, "we all want to be cool people who are good at science." A scientific publication's potential conflict of interest usually refers to the authors' financial, familial, or other external interests in the research outcomes. The disclosure statement does not describe a conflict between the authors' {{w|extrinsic motivation}}s and factors influencing the accuracy and neutrality of their work; in fact it claims the opposite, an alignment between their {{w|intrinsic motivation}}s and the goal of producing high quality work, which should go without saying.{{cn}}

2701: Change in Slope

}}

==Explanation==
{{incomplete|Created by a SIDEWAYS STATISTIC. Do NOT delete this tag too soon.}}

The comic is a tip for detecting changes in slopes over a {{w|scatter plot}} of data. This is a common requirement in exploratory statistics for comparing trends in a series — finding the cutoff where the slope changes may reveal valuable information about the data.

The comic compares two methods. Firstly, a novice method — by 'doing a bunch of statistics'- i.e, applying various statistical tools to analyze the data and figure out the quantitative change in slope. This results in two equations for the trendlines above and below a given value, a box plot, a histogram, and a line chart. It is unknown exactly what methods the novice used to figure out the change in slope in the data. Possibilities include calculating the [https://stackoverflow.com/a/45063636 derivatives] (which probably won't work well on noisy data such as shown), or the [https://stackoverflow.com/a/71744293 gradients], or using a [https://stackoverflow.com/a/47522444 Savitzky-Golay filter or piecewise linear smoothing spline fits].

The other is the so-called 'expert' method, which involves [https://cdn.discordapp.com/attachments/525939879805190154/1044395695525875712/xkcd_sideways.png tilting the page the graph is printed on to view changes in slope] better. For small changes in an underlying trend, similar to that apparently shown in the comic, direct visual inspection cannot always identify or even reveal the effect. The comic shows, however, that by taking the page and rotating it in just the right way, the foreshortened perspective can make certain details much more apparent, allowing the 'expert' to see at a glance that there is a change in the slope. Ironically, tilting the comic to make the original roughly resemble the perspective of the 'tilted' version graph shown in the comic shows that the right-hand panel is slightly exaggerated for visual effect. The use of {{w|Perspective (graphical)|perspective}} to make information pop into the audience's view has been used by artists for {{w|The_Ambassadors_(Holbein)|centuries}}.

The effect works because tilting an image results in it appearing to be scaled down, while not changing the location of points within the image. This means that for computerised data, the same effect can be achieved without making a physical copy of the graph by resizing the image, or by changing the range on the axes so that the points appear closer together.

However, applying such an approach to data plots can run into errors — the primary one being parallax error from the oblique viewing angle causing the observer to not necessarily identify or clearly find the point at which the slope changes. It also does not reveal any data about the quantitative value of the change in slope, merely proving the existence of one. Furthermore, noisy data might show an apparent slope change that is not representative of an actual change in the underlying data, so even more advanced [https://www.danielsoper.com/statcalc/calculator.aspx?id=103 statistics testing the hypothesis of whether an apparent slope change is real] may likely be a good idea.

The title text then goes on to say that, while such a trick is useful to identify that there is some change in slope, in order to ''pretend'' to know it exactly one must revert to statistics (the "novice method") to obtain some form of information, defeating some of the premise of the comic. This at least produces a semblance of statistical rigor although, once an answer appears obvious, data could be interpreted to reach an answer that you are now expecting rather than revealing something of more statistically useful significance.

}}

==Explanation==
{{incomplete|Created by a GROUP OF SCHOOLCHILDREN DIVIDED AMONGST THEMSELVES. Do NOT delete this tazg too soon.}}

This comic pokes fun at some of the ways to write the {{w|Division (mathematics)|division}} operation in math. In this comic, [[Randall]] has used A as the dividend (the number being divided) and B as the divisor (the number that A is divided by). Division is the fourth simplest arithmetic operation in mathematics, after addition, subtraction, and multiplication.[https://plato.stanford.edu/entries/principia-mathematica/#PartIVRelaArit]

The first two of the seven notations shown are the {{w|division sign}} (÷) and the {{w|long division}} notation used for {{w|short division}} and {{w|long division}} in beginning arithmetic. (Note: division typography is only used in some countries, and there are [https://en.wikipedia.org/wiki/Long_division#Notation_in_non-English-speaking_countries different notations in the non-English speaking world]). These methods of division are often used by school children because the ÷ sign is what most people use when first learning division, and the short division format is usually the first algorithm learned for dividing arbitrary dividends, typically starting with the easier abbreviated short division form.

The expression on the third line, A/B, is the way division is usually written in software code. The four simple arithmetic operations in programming usually are +, -, *, /. This one was missing in the first version of the comic. This is most commonly seen in regular mathematics as it somewhat saves space, and is easy to type with the slash key. Additionally, it uses standard {{w|ASCII}} characters instead of sophisticated notation.

The expression on the fourth line, a/b, is how division is usually written by hand. It is nearly identical to the fraction notation that follows, but the diagonal line allows each number to be bigger while still fitting into a single line of text. It takes more effort to type with this notation; however, the Unicode character sets provide some specific fractions such as ⅓ as well as some superscript and subscript characters, so someone familiar with it might use it to write fractions such as ²²⁄₇.

The fifth notation is the way division is written in science: the dividend on the top of the expression over the divisor on the bottom under a horizontal line. This is how a {{w|Fraction|fraction}} would be written. It has the advantage of clearly separating the numerator and denominator when they are longer expressions, such as polynomials, without needing to add parentheses. This format is mostly used in written and professionally typeset math, as it can't be typed without something like {{w|MathML}}, {{w|LaTeX}} or HTML tables.

The sixth, "fancy," notation uses a negative exponent. The exponent -1 is equivalent to {{w|Multiplicative inverse|reciprocation}}. It can be used to keep an entire division expression on one line. Note that AB-1 is equal to A/B only if A and B are in a commutative ring (and B has an inverse). If A and B are, for example, matrices, AB-1 is not the same in general as B-1A (and the notation A/B is never used in this case as it would be ambiguous).

The AB-1 format is also often used to express physical units.

The final form of notation declares a function. The writer defines a new function, F, that takes in the parameters A and B, before listing out the function's definition (trailing off in increasingly smaller text). Randall warns the reader they should escape while they still can, because both the function itself and the math environment as a whole are going to get relatively tedious. Integer division can be defined in terms of multiplicative inequalities and the remainder, or modulo ('%' in Python), operator. This situation is likely to occur in many sorts of algebra, where one might have to define what "division" means for two elements of a mathematical object such as a group, ring, or magma. One example would be an object G, such that, for two elements A and B of G, "A divided by B" is defined as an element C such that CB=A, or alternatively as an element C such that BC=A. These definitions will differ if multiplication in G is not commutative. Furthermore, if such a C is not unique, the function F(A,B) will need to include a method to select a unique value for "A divided by B" for each A and B. Thus, the F(A,B) in the comic might not even refer to a uniquely defined operation, but simply to the property of a function F(A,B) that is a valid division operation on G, given some definition of division. You were warned.

The title text discusses how the division sign (÷) has fallen out of favor in most professional contexts (the ISO-80000 guidelines even specify the symbol "should not be used") yet has resisted all efforts to repurpose it as a new function.

Fun fact: In Poland, we don't write the long division like that; we just write A:B with the bar above. I was VERY confused the first time I saw that notation. [[Special:Contributions/172.70.246.235|172.70.246.235]] 21:03, 19 October 2022 (UTC)

:In German elementary school we learned the a:b notation. When we learned more complex divisions in secondary school it was with the "scientist" notation. And as I am a software engineer AND (presumably) a normal person I use in general the respective notations.

For me, the version on the xkcd website has an additional line ("A/B: Software Engineer") that's not on this site. I think the comic might have been updated. Is anyone else seeing that? [[User:JBYoshi|JBYoshi]] ([[User talk:JBYoshi|talk]]) 23:20, 19 October 2022 (UTC)

"the long division symbol is only used in some countries". Only English-speaking ones, to be more precise. Most of the countries of the world use a different notation. [[Special:Contributions/172.68.51.80|172.68.51.80]] 06:19, 20 October 2022 (UTC)

In the UK, the 'long division symbol' is nowadays often referred to (particularly with Primary classes, children aged 4 - 11) as the "Bus Stop Method". Because it looks like a UK bus shelter. [[User:MarquisOfCarrabass|MarquisOfCarrabass]] ([[User talk:MarquisOfCarrabass|talk]]) 07:07, 20 October 2022 (UTC)

As a Dutch primary schoolchild, I have used a÷b for calculations and "a over b" for fractions (e.g. ⅘).
For more difficult divisions, like what is 785/35, we used [https://nl.m.wikipedia.org/wiki/Staartdeling Staartdelingen] (nl), long division, of which the primary notation is 35/735\.
I think in early highschool we started using a over b for more complex calculations, "like (x+3) over 5 = 2, what is x". I had up to this XKCD never seen B⟌A, and would confuse it for what we use as square root symbol (√). [[User:IIVQ|IIVQ]] ([[User talk:IIVQ|talk]]) 07:16, 20 October 2022 (UTC)
:Come to think of it, it's kind of odd that we used ":" for division. Why are there this many different division notations anyway? Same for multiplication. There's x, *, ⋅, x but centered vertically, and concatenation (for letter variables)!
:: The : operator is for ratios, where a:b could be a/b or b/a, but also metaphors, where a:b::c:d means a is to b as c is to d. [[Special:Contributions/162.158.166.73|162.158.166.73]] 09:05, 20 October 2022 (UTC)

2676: Historical Dates

172.69.134.161: Copy intro from earlier version

}}

==Explanation==
{{incomplete|Created by a CONFUSED HISTORIAN BORN ON DECEMBER 30TH - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Many files and database entries contain a date. When it is not set, it often defaults to the first day in the system.

===Dec 30th, 1899===
Dec 30th, 1899 comes from a [https://www.joelonsoftware.com/2006/06/16/my-first-billg-review/ spreadsheet date compatibility issue] between Excel and Lotus 1-2-3 (referenced in the title text.) Spreadsheets store dates as sequential numbers so that they can be used in calculations. In Excel, by default, January 1, 1900 is number 1 [https://support.microsoft.com/en-us/office/datevalue-function-df8b07d4-7761-4a93-bc33-b7471bbff252]. Based on that, Excel's integer date representation would be the number of days that have passed since December 31, 1899. However, because of a bug intentionally carried over from Lotus 1-2-3 where it counts February 29, 1900 as a day even though it actually was not [https://learn.microsoft.com/en-us/office/troubleshoot/excel/wrongly-assumes-1900-is-leap-year], for any day since then, Excel's integer date representation is actually the number of days that have passed since December 30, 1899. Most other spreadsheet applications copied the behavior of Excel to maintain compatibility with it. This leads to the value of 0 in some applications (notably Open- and LibreOffice Calc and Google Spreadsheets) being interpreted as Dec 30th, 1899. Similarly, Microsoft Visual Basic and Visual Basic for Applications (VBA) interpret 0.0 as Dec 30th, 1899.

The historian in the comic presents some research wrongly based only on the number of entries created on those dates. This confusion on the part of the future historian only grows in the title text, where they make the claim that Lotus 1-2-3 is, in fact, religious imagery related to some sort of deity, potentially a lotus god, around whom the '1899 event' took place. This may be poking fun at the trope that anthropologists attribute any behavior they can't explain to religious ritual.{{Citation needed}} This historian's confusion may have been at least partially due to China's {{w|White Lotus|White Lotus Religion}}.

===Jan 1st, 1970===
Many files and database entries contain a date. When it is not set, it often defaults to the first day in the system. Many operating systems and software store dates as [https://en.wikipedia.org/wiki/Unix_time Unix timestamps], which are defined as the number of seconds since Jan 1st, 1970, 0:00 UTC. When data entry neglects to provide a value, the system may be programmed to treat it to 0; consequently, an unprovided timestamp value is interpreted as Jan 1st, 1970 thereby creating the illusion of an "activity spike" on that date.

2679: Quantified Self

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

[[Cueball]] embraces the {{w|quantified self}}, a popular philosophy promoting monitoring yourself with devices and data in the hope to help your well-being. He does so in a unique and absurdly humorous way, with help from a smart watch or handheld mobile device. [[Randall]]'s caption indicates he is interested in the quantified self for unusual quantities.

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

This comic appeared two days after [https://blog.google/products/search/new-ways-to-make-more-sustainable-choices/ Google's announcement that Maps Directions will be sortable by sustainability,] along with their support of self-quantification for sustainability when shopping for automobiles, used goods, and food. This may be particularly notable because of tech industry discussions between employees and executives about cost-benefit analyses comparing sharply increased profits and productivity from work-from-home to the value of coastal region commercial office space holdings and leases, relative to [https://www.epa.gov/climateleadership/scope-3-inventory-guidance scope 3 emissions].[https://www.latimes.com/business/technology/story/2021-04-28/google-is-saving-1-billion-per-year-as-a-result-of-employees-working-from-home][https://www.wsj.com/articles/companies-cutting-office-space-predict-long-term-savings-11625493601][https://www.bloomberg.com/news/articles/2021-07-15/google-googl-wants-employees-to-return-to-office-despite-productivity-gains][https://www.reuters.com/world/the-great-reboot/pay-cut-google-employees-who-work-home-could-lose-money-2021-08-10/][https://www.forbes.com/sites/jackkelly/2022/01/14/google-spends-billions-on-buying-office-buildings-is-this-a-sign-of-the-post-pandemic-pushback-against-remote-work/][https://www.computerworld.com/article/3659891/google-others-adding-office-space-in-anticipation-of-the-great-return.html]

An "imaginary thread" connecting a person to where they came from (as portrayed in this comic, distinct from a mystical {{w|silver cord}} or {{w|red thread of fate}}) has been attested[https://www.reddit.com/r/OCD/comments/1ve309/invisible_thread_attached_to_my_back_am_i_the/][https://www.reddit.com/r/xkcd/comments/xs50yr/xkcd_2679_quantified_self/iqjcmbv/?context=3] by some experiencing OCD conditions (Obsessive-compulsive disorder; see also [[245: Floor Tiles]], [[100: Family Circus]].) See below for further elaboration.

The title text mentions several things that would make the red path longer: passing (one way) through a tube (water slide) or tunnel (subway or car wash), riding on a ferris wheel, or entering a building through one door and exiting another, in all cases the imaginary string would be "captured" and make the total distance longer.

===OCD interpretation===

The quantity Cueball measures can be recognized as a specific type of OCD where people feel like they have an imaginary string connecting them to where they come from.{{Actual citation needed}}

As they move around, that string gets entangled and they feel the urge to untangle it. When they enter a car, they feel the need to exit the car from the same door, to avoid that the string gets trapped by forever passing through the car. When they enter a building, they feel they need to exit using the same staircases and doorway(s), to avoid entangling the string in the building. Some situations, like turning around a lamp post, are OK because you can imagine removing the loop over the top of the lamp post, such that it is not really entangled.

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

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

This may be particularly notable because of tech industry discussions between employees and executives about cost-benefit analyses comparing sharply increased profits and productivity from work-from-home to the value of coastal region commercial office space holdings and leases, relative to [https://www.epa.gov/climateleadership/scope-3-inventory-guidance scope 3 emissions].[https://www.latimes.com/business/technology/story/2021-04-28/google-is-saving-1-billion-per-year-as-a-result-of-employees-working-from-home][https://www.wsj.com/articles/companies-cutting-office-space-predict-long-term-savings-11625493601][https://www.bloomberg.com/news/articles/2021-07-15/google-googl-wants-employees-to-return-to-office-despite-productivity-gains][https://www.reuters.com/world/the-great-reboot/pay-cut-google-employees-who-work-home-could-lose-money-2021-08-10/][https://www.forbes.com/sites/jackkelly/2022/01/14/google-spends-billions-on-buying-office-buildings-is-this-a-sign-of-the-post-pandemic-pushback-against-remote-work/][https://www.computerworld.com/article/3659891/google-others-adding-office-space-in-anticipation-of-the-great-return.html]

An "imaginary thread" connecting a person to where they came from (as portrayed in this comic, distinct from a mystical {{w|silver cord}} or {{w|red thread of fate}}) has been attested[https://www.reddit.com/r/OCD/comments/1ve309/invisible_thread_attached_to_my_back_am_i_the/][https://www.reddit.com/r/xkcd/comments/xs50yr/xkcd_2679_quantified_self/iqjcmbv/?context=3] by some experiencing OCD conditions (see also [[245: Floor Tiles]], [[100: Family Circus]].)

The title text mentions several things that would make the red path longer: passing (one way) through a tube (water slide) or tunnel (subway or car wash), riding on a ferris wheel, or entering a building through one door and exiting another, in all cases the imaginary string would be "captured" and make the total distance longer.

===OCD interpretation===

The quantity Randall measures can be recognized as a specific type of OCD where people feel like they have an imaginary string connecting them to where they come from.[https://www.reddit.com/r/OCD/comments/1ve309/invisible_thread_attached_to_my_back_am_i_the/][https://www.reddit.com/r/xkcd/comments/xs50yr/xkcd_2679_quantified_self/iqjcmbv/?context=3]{{Actual citation needed}}

As they move around, that string gets entangled and they feel the urge to untangle it. When they enter a car, they feel the need to exit the car from the same door, to avoid that the string gets trapped by forever passing through the car. When they enter a building, they feel they need to exit using the same staircases and doorway(s), to avoid entangling the string in the building. Some situations, like turning around a lamp post, are OK because you can imagine removing the loop over the top of the lamp post, such that it is not really entangled.

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

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

Talk:2677: Two Key System

2022-09-28T02:53:14Z

172.69.134.161: Tdlr

Ah, for many long moments, I thought the "dual-key-turner" was a "dual-key-''cutter''" (but that it was a silly implemention, anti-parallel coaxial positioning of key blanks needs a complicated (pantograph?) cutting-heads system, more so than with parallel and adjacent blanks of ''any'' number). But now I'm on the right track and I laugh at the ''correct'' joke, and can think of any number of developments in safe (as in not 'forgotten') and secure (as in not misappropriated) password use that went into and out of the various "convenience for user"/"security for systems" modes, often mutually exclusive to the other mode. [[Special:Contributions/172.70.90.61|172.70.90.61]] 15:33, 26 September 2022 (UTC)

I've long been annoyed that I can't use password auto-fill on Chrome's online password manager webpage. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 16:36, 26 September 2022 (UTC)

Do you remember how banks were all "two-factor authentication" when we used to access them from computer and made us use the phone for confirmation? And how they don't seem to mind now when the bank can be completely controlled just from the (smart)phone? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 20:35, 26 September 2022 (UTC)

Although I think this extends well beyond 'merely' "passwords" (in all their forms and combinations, from PINs to fingerprints!) I've taken the general feeling so far seen here in Talk and bulked up the explanation with the allegorical connections that ''might'' be the source of inspiration for the comic. And if you gave me the time to do it, I'd put an awful lot more (strange, really, I was often tired of rewriting SOPs to reflect the latest best-practices in 2FA/3FA when that was actually a big part of my job! "What you know/What you have/What you are"...) and without skipping over huge chunks. But (even if some bits get cut back down again) I think I've added value and maybe some narrative flow to the initial explanation, which was ok but perhaps not even how I would have arranged it (having then tried to preserve that skeleton arrangement of ideas). Darnit, I now sound full of myself. That's just me winding down from a big hot-edit that maybe even was too big, and anxiously awaiting someone else doing an even better total-rewrite/summary, regardless of what I just splurged there... ;) ((But, to clarify, the comic never mentions passwords. Highly likely it is (keys!) but it could be more wider ranging development issues. I'm sure I'll understand the moment someone clues me in on some other scope that this might actually reference.)) [[Special:Contributions/172.70.90.245|172.70.90.245]] 22:00, 26 September 2022 (UTC)

Just to add something 'from the old days' (n.b., probably still applies to many non-web server logins, just rarer in more ubiquitous weblogins) is that any system that forces users to regularly change their passwords also tended to encourage the use of "Password1", "Password2", "Password3", sequentially (well, at least then you had a recent password to refresh in your mind), as they ''at least'' disallowed the immediate reuse of the last current password to replace itself, and possibly 'remembered' a number of past incarnations. But you tend not to get that feature (forced change/no reuse) on much of the modern infrastructure. It tends to focus more on a general form ("use special characters/uppercase!", as well as minimum lengths), which doesn't preclude bad 'sequential' practices (if you're even needing to do that) if you get ever "g!b³riZh1", "g!b³riZh2", "g!b³riZh3" started, then compromised by whatever means or reason... [[Special:Contributions/172.70.85.49|172.70.85.49]] 22:45, 26 September 2022 (UTC)

"This could also be something of a reference to ‘two factor authentication’ a security annoyance which also requires ‘two keys’ (typically something from a dynamic physical token, as well as the static password which is susceptible to unauthorised reuse) that was adopted by more secure websites." - a stretch too far, IMO. This is a situation that has never gone from 'two keys' to 'one key (operator)' and back to 'two keys'. If anything, it might have been 2FA(password + token)->2FA(browser/password-manager + token), or even 1FA(password)->1FA(browser/whatever)->2FA( +token) for the slower/earlier adopters who had not originally worked out the token element. I've commented it out, because it isn't a good enough fit to really fit the analogy presented. Unless one of the other experts here can radically fix it to do so.
 I don't personally use third-party PMs (either it's safe enough to just let the browser manage it, for convenience, or I actually remember all the individual passwords for things and untick any "Save password?" suggestion it gives me) so I also don't know how much 2FA is built into them in order to authorise them to "dual-key turn" (or if they even turn more than the one key, in any logical way), if you don't count the use of the installed PM itself as a virtual "possession" factor somehow. And I don't bank online, because I've never seen the advantages outweigh the potential problems. [[Special:Contributions/162.158.159.19|162.158.159.19]] 18:51, 27 September 2022 (UTC)

With regard more specifically to software development, I think you'll find parallels with being able to run code (or, put another way, separating code from data). Once multi-user systems became a thing, it became important for systems to control what code could be executed on a computer. However, with any new system, programmers are always looking at ways to automate it, and they often create new ways for getting code into the system. Interpreters that allow processing of inputs as code are a common example of this. [[Special:Contributions/172.71.150.63|172.71.150.63]] 19:48, 27 September 2022 (UTC)

The current explanation is extremely verbose for such a simple concept, joke, and title text rejoinder. Lots of the discussion is not really on topic. Can we pull some of it out into a "Further considerations" subsection perhaps? [[Special:Contributions/172.69.134.161|172.69.134.161]] 02:53, 28 September 2022 (UTC)

Many of these rely on "ia"/"ie"/"io" serving as the 3rd and 4th syllables, so every song would be sung like "God Bless Olimpiya". Virginia Beach appears to be the only one to escape this.--[[User:Magtei|Magtei]] ([[User talk:Magtei|talk]]) 19:39, 29 August 2022 (UTC)in M
:As a Washingtonian, I pronounce Olympia without the diphthong (so four syllables; the “a” being distinct).

Aussie here: we tend to say (and sing) "Australia" with three syllables.

==Explanation==
{{incomplete|Created by a CAFFEINE MOLECULE WITH A HOLE DRILLED IN ITS SIDE. Do NOT delete this tag too soon.}}

This comic depicts people in different fields of study answering the question, "How many holes are there in a coffee cup?" This question has different interpretations depending on the definition of a hole.

[[File:Mug and Torus morph.gif|thumb|200px|The coffee mug and donut shown in this animation both have topological genus one.]]

[[Ponytail]], a {{w|topology|topologist}}, states the coffee cup belongs in the {{w|Genus (mathematics)#Topology|genus}} of one hole. A common joke is that topologists can't tell the difference between a coffee cup and a donut since they're homeomorphic to each other — meaning they have the same genus. From the topologist's point of view, the coffee cup definitely has one hole. See [[2625: Field Topology]] for more information about topology.

[[Hairy]], a normal person, is not sure (the acronym "IDK" stands for "I don't know") and asks for clarification about whether the opening at the top counts as a hole. This shows flaws in the question, which suffers from the mathematically imprecise, ambiguous common usage of the word hole. Topologists would refer to the opening as a concavity, not a hole, and while they consider such geometrical properties generally outside their field, most practical applications of topology do involve geometric components.

[[File:Double torus illustration.png|thumb|left|200px|A genus two surface]]

[[Hairbun]], a philosopher, answers the question with an elucidating counter-question, considering a hypothetical scenario. Drilling a new hole should increase the number of holes by one. After the hole has been drilled, a common teacup or mug has two holes according to topologists. Therefore, the philosopher's question requires the original questioner to reveal the answer to their own question. (Also, she asks how many holes there are ''now'' rather than ''after we do that'', an ambiguity.)

[[Image:Point cloud torus.gif|thumb|200px|A point cloud of a genus one surface]]

[[Cueball]], a chemist, looks at the coffee in the cup on a molecular level, which means it has very many holes: 1,000,000,000,000,000,000,000 (1021 or 1 sextillion) “in the [https://chemapps.stolaf.edu/jmol/jmol.php?model=CN1C%3DNC2%3DC1C%28%3DO%29N%28C%28%3DO%29N2C%29C caffeine] alone.” One molecule of caffeine has two rings of bonds with holes in them, so Cueball is talking about 500 quintillion molecules, or 0.00083 {{w|mole (unit)|moles}}. As the molecular mass of {{w|caffeine}} is about 194 grams per mole, [[Randall]] must think that the mass of caffeine in a typical cup of coffee is 161 milligrams. The coffee could have other holes, depending on the type of coffee; for example, espresso contains significant amounts of niacin and riboflavin, which have one and three rings in their chemical structure, respectively. However, bonds are not sticks as portrayed in many molecular models. The "holes" in the middle of a molecule's rings are not completely empty but instead merely have lower electron probability density through the middle than other parts of the bonds. So the point-cloud duality of {{w|Bonding molecular orbital|electron orbitals and bonds}} might not satisfy a topologist's, normal person's, or philosopher's criteria for a connected substrate in which holes may be formed.

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

In the title text, a theoretical physicist looks even deeper, at the subatomic scale of {{w|Planck units}}. Since fundamental particle interaction is governed by fundamental forces and collision (per the {{w|Pauli exclusion principle}}) instead of tensile or ductile solid connectedness, the theoretical physicist posits that any definition providing for a single hole would also describe a number of holes akin to the factorial of the number of particles in the universe,[https://tel.archives-ouvertes.fr/tel-02341882/document] or at least within the cup's {{w|light cone}}, which is a number impractical to accurately count, but not uncountable in a mathematical sense.

Part of the joke could be that all five methods of inquiry don't discern between a {{w|cup}} (as described) and a {{w|mug}} (as depicted), the cliché being that topologists are unusual because they don't. Or, as many people use the terms interchangeably, Randall may too. A cup without a handle is topologically equivalent to either a flat disk (if the cup' walls are assumed to have no thickness) or an amorphous sphere (if the cup's walls have thickness.)

This shows flaws in the question, which suffers from the mathematically imprecise, ambiguous common usage of the word hole. Topologists would refer to the opening as a concavity, not a hole, and while they consider such geometrical properties generally outside their field, most practical applications of topology do involve geometrical components.{{cn}}

[[File:Double torus illustration.png|thumb|left|150px|A genus-2 surface]]

[[Hairbun]], a philosopher, answers the question with an elucidating counter-question, considering a hypothetical scenario. Drilling a new hole should increase the number of holes by one, and after the hole has been drilled, a common teacup or mug has two holes according to topologists. Since drilling a hole increases the number of holes by one{{cn}}, the philosopher's question requires the original questioner to reveal the answer to their own question.

[[Image:Point cloud torus.gif|thumb|150px|A point cloud of a genus one surface]]

[[Cueball]], a chemist, looks at the coffee in the cup on a molecular level, which means it has very many holes: 1,000,000,000,000,000,000,000 (1021 or 1 sextillion) “in the [https://chemapps.stolaf.edu/jmol/jmol.php?model=CN1C%3DNC2%3DC1C%28%3DO%29N%28C%28%3DO%29N2C%29C caffeine] alone.” The implication is that there are more in the cup itself, depending on what material it’s made out of. Also, the coffee itself could have other holes, depending on the type of coffee. For example, espresso contains significant amounts of niacin and riboflavin, each of which has at least one hole in its chemical structure. However, this ignores the fact that bonds are not discrete sticks as portrayed in many molecular models. The "holes" in the middle of a caffeine molecule are not completely empty but instead merely have lower electron densities/probabilities. In a {{w|space-filling model}}, a caffeine molecule has zero holes. So the point-cloud duality of {{w|Bonding molecular orbital|electron orbitals and bonds}} might not satisfy a topologist's, normal person's, or philosopher's criteria for a connected substrate in which holes may be formed.

[[Image:World lines and world sheet.svg|left|thumb|150px|{{w|String theory}} describes the {{w|worldline}}s of point-like particles as {{w|worldsheet}}s of "closed strings," forming topological holes.]]

In the title text, the theoretical physicist looks even deeper, at the subatomic scale of {{w|Planck units}}. Since fundamental particle interaction is governed by fundamental forces and collision (per the {{w|Pauli exclusion principle}}) instead of tensile or ductile solid connectedness, the theoretical physicist posits that any definition providing for a single hole would also describe a number of holes akin to the factorial of the number of particles in the universe, or at least within the cup's {{w|light cone}}, which is a number impractical to accurately count, but not uncountable in a mathematical sense.

Part of the joke could be that all five methods of inquiry don't discern between a cup (as described) and a mug (as depicted), the cliché being that topologists are unusual because they don't. Or, as many people use the terms interchangeably, [[Randall]] may too.

1561: Water Phase Diagram

2022-06-29T20:23:08Z

172.69.134.161: /* Explanation */

{{comic
| number = 1561
| date = August 7, 2015
| title = Water Phase Diagram
| image = water_phase_diagram.png
| titletext = Vanilla Ice was produced in small quantities for years, but it wasn't until the 90s that experimenters collaborated to produce a sample that could survive at room temperature for several months.
}}

==Explanation==
This is a modified version of the {{w|phase diagram}} for {{w|water}}. A "phase diagram" is a chart that shows the states, or "phases", that a substance will be in under various temperatures and pressures. {{w|Ice#Phases|Water's phases}} are particularly well-studied; on the [https://webhome.phy.duke.edu/~hsg/363/table-images/water-phase-diagram.gif real phase diagram for water], there are a great many phases listed.

Most people are familiar with three phases of water — solid ({{w|ice}}), liquid (water), and gas ({{w|Water vapor|vapour}}) — and with the fact that an increase in temperature will cause water to change from one state to another. The gas and liquid phases are quite straightforward; however, there is in fact not one single solid phase of water, but a variety of numbered phases ("ice I" through "ice XVI" are currently recognized), several of which are divided into sub-categories. Ordinary, everyday ice that forms on most parts of the Earth's surface is known as "{{w|Ice Ih|ice Ih}}" ("ice one-h"). Most of the more unusual forms of ice only form under very {{w|high pressure}}.

[[Randall|Randall's]] phase diagram starts out realistically, though slightly simplified in several ways. For one, ice Ih is simply called "ice". It is focused in on a narrower area than the more complete diagram linked earlier; on that version, the "ice V" region is quite small, and "ice III" is barely visible, whereas both are quite plain to see on Randall's diagram. Lastly, where most phase diagrams have pressure increase upwards, Randall has the pressure scale increase downwards, this has been chosen to make it possible for the jokes to appear at the bottom of the chart. Else the comic would not be funny for the average reader.

Because, as the diagram continues downwards and the pressure increases, the jokes begin. Beyond the moderately high-pressure forms of ice (ice II, III and V), a real phase diagram has ice VI; Randall has "Vanilla Ice (ice VI)". {{w|Vanilla Ice}} is the stage name of a white rap/hip-hop artist from the 1990s; the initials of Vanilla Ice, and the Roman numeral six, are both VI.

Vanilla Ice's biggest hit, "{{w|Ice Ice Baby}}", used samples from the earlier song "{{w|Under Pressure}}", by {{w|David Bowie}} and {{w|Queen (band)|Queen}}; accordingly, on Randall's diagram, the "Vanilla Ice" region transitions to "David Bowie & Queen" when it is under (even higher) pressure.

Further references to "Ice Ice Baby" are found in the title text. Near the beginning of the song, Vanilla Ice raps the line, "All right stop, collaborate and listen". The unusual choice of "collaborate" in this line has made it memorable, and the word is used in the title text (in a more typical context). The phrase "survive at room temperature for several months" is likely a reference to "Ice Ice Baby" being Vanilla Ice's only major hit, humorously suggesting he faded out of the public view after a few months of fame. Finally, even the word "sample" may be deliberately chosen as a reference to the sampling of "Under Pressure". "Ice Ice Baby" was written in 1983, but in {{w|Ice_Ice_Baby#Lyrics_and_music|1990}} Vanilla Ice finally admitted that he used unmodified samples from "Under Pressure" and paid royalties to Queen and Bowie.

===Original version===
[[File:WaterPhaseEdit.png|frame| The original comic, with a lower contrast, showing [https://commons.wikimedia.org/wiki/File:Phase_diagram_of_water.svg the real phase diagram for water] from Wikipedia]]
When originally published, another image was faintly visible just below and to the right of the "Water vapor" label. It appeared to be a copy of [http://commons.wikimedia.org/wiki/File:Phase_diagram_of_water.svg an actual phase diagram for water from Wikipedia]. The image has since been removed, lending support to speculation that it was an error (perhaps an image Randall referred to in drawing the comic, but accidentally left in the final result). Alternatively, it may have been deliberate—suggestions include its presence being a ''water''mark, or a reference to the "Full text of the Wikipedia article on pareidolia" joke in the [[1551: Pluto]] comic.

===Related comics===
Randall has referenced "Ice Ice Baby" and "Under Pressure", separately and together, on many previous occasions, notably in [[159: Boombox]] and [[210: 90's Flowchart]]. The gag of having the performers of "Under Pressure" also being literally under pressure was also used in [[1040: Lakes and Oceans]].

The [[what if?]] that was current at the time of this comic's publication was [http://what-if.xkcd.com/138/ 138: Jupiter Submarine], which began with an even more fanciful phase diagram: that of a submarine. It also contains a reference to the songs "Under Pressure" and "Ice Ice Baby" in one figure, and "Can't Touch This" by M.C. Hammer in the title text of that figure (which generated similar controversy for sampling "Superfreak" by Rick James).

The title text of [[1434: Where Do Birds Go]] whimsically suggests another possible phase of water/ice.

As mentioned above, the small image on the [[#Original version|original version]] could be a reference to the "Full text of the Wikipedia article on pareidolia" joke in the [[1551: Pluto]] comic.

2621: Mainly Known For

{{comic
| number = 2621
| date = May 18, 2022
| title = Mainly Known For
| image = mainly_known_for.png
| titletext = Oh sure, I know Keira Knightly, from the first movie in that series by The Land Before Time producer. You know, the franchise with the guy from Jurassic Park and Ghostwriter, and script work by Billie Lourd's mom?
}}

==Explanation==
{{incomplete|Created by that guy from NASA, what was his name? Something Munroe - Do NOT delete this tag too soon.}}
[[Megan]] points out an uncanny resemblance between someone's dad and {{w|Steve Jobs}}. However, she is uncertain that Steve's last name is Jobs, so she refers to Jobs as "the Pixar guy", asking Cueball if Jobs is the correct name. Jobs is ''mainly known for'' (hence the comic's title) being the co-founder and twice CEO of {{w|Apple Inc.}}, but in the late 1980s and early 1990s (between his stints at Apple), he was the chairman of {{w|Pixar Animation Studios}}, which is what Megan knows him for.

Frequently, when people can't remember a celebrity's name, they will point out other works they are known for in hopes someone else will recognize them from that and remind them of the name. The comic, for its demographic of nerds, is joking on how it can come across to have lived a life separate from popular culture, where one learns things for different reasons than most people do.

[[Cueball]] points out that Megan's tendency to avoid the "main" association and instead go with a much more secondary one is weird, which confuses her. To demonstrate how weird her associations are, Cueball asks her, "Who is {{w|John Lennon}}?" Lennon is a famous songwriter who played and wrote for {{w|The Beatles}} before they broke up, and later continued on a solo music career. Megan recognizes Lennon as a musical artist, but is unable to remember the name of The Beatles. She instead asks about the band he was in with {{w|Ringo Starr}}. Ringo, however, is not mainly memorable to her for his role in The Beatles, but rather as Mr. Conductor from the first season of the 1989 children's television show ''{{w|Shining Time Station}}''. The Beatles' fame seems to have escaped Megan, which vexes Cueball. Also Ringo may be considered as the least known of The Beatles, unless that would be {{w|George Harrison|'the quiet one'}}. Definitely less well-known than {{w|Paul McCartney}}, who was often as prominent a writer-performer as Lennon at the time and has continued to prominently perform individually (or headlining collaborations) across all the intervening decades since that era.

Hoping to show that she really does know Lennon and that her associations aren't weird, she points out that she remembers John doing a song with {{w|David Bowie}}. But she cannot remember that it was called "{{w|Fame (David Bowie song)|Fame}}". The song is from 1975 and Lennon co-wrote it with Bowie and performed backing vocals and guitar on it. Also she cannot remember Bowie's name, recognizing him instead for his acting role in ''{{w|Labyrinth (1986 film)|Labyrinth}}''. When Cueball states Bowie's name and adds, presumably sarcastically, that he think he is famous for other stuff than those two things Megan mentions, she also remember another movie with Bowie, ''{{w|Zoolander}}'', rather than his more famous musical career (such as his smash hits "{{w|Space Oddity}}" or "{{w|Let's Dance (David Bowie song)|Let's Dance}}").

Sensing Cueball's annoyance, but failing to understand it, she attempts to excuse herself for not remembering ''Zoolander'' to begin with, because it came out a long time ago, during the {{w|Presidency of George W. Bush}}. ''Zoolander'' was indeed released in 2001. Apparently unable, again, to remember the president's name, she identifies him as "{{w|Jenna Bush}}'s dad". Jenna Bush is a TV personality and much less widely known than her father.

While the kind of associations people make like Megan in this comic, are often prone to the {{w|Mandela effect}}, Megan's information about all the celebrities is, in fact, correct, but apparently they are never what those people are best known for. This is what makes Cueball sigh and facepalm in the final panel, when she mentions Jenna instead of George Bush. He likely also does this because, even though he just demonstrated her weird tendency to remember people for their lesser known works, he is unable to reach her and let her understand that she is weird.

In the title text, Megan refers to "{{w|Keira Knightley|Keira Knightly}}" [''sic'' -- her surname is spelled Knightley], who is probably best known for her roles in the {{w|Pirates of the Caribbean (film series)|''Pirates of the Caribbean'' films}} and the {{w|Pride & Prejudice (2005 film)|2005 ''Pride and Prejudice'' film}}, by referencing her small role in ''{{w|Star Wars: Episode I – The Phantom Menace}}'' (as Sabé, who funnily enough is a handmaiden and ''decoy'' for Queen Padmé Amidala, a main character played by Natalie Portman).

Megan continues her unusual references by identifying the film as the "first movie" (it was the first in the plotline, but the fourth one made) in "that series by ''The Land Before Time'' producer" ({{w|George Lucas}}, creator of {{w|Star Wars}}, was also one of the executive producers of the 1988 animated film ''{{w|The Land Before Time (film)|The Land Before Time}}'').

Seeming to think that identifying George Lucas doesn't narrow it down at all, she identifies another actor in the ''Star Wars'' series, {{w|Samuel L. Jackson}}, by his roles in ''{{w|Jurassic Park (film)|Jurassic Park}} ''(an extremely successful film, but one in which Jackson had a relatively small role) and the PBS children's series ''{{w|Ghostwriter (1992 TV series)|Ghostwriter}}'' (in which Jackson appeared in only a few episodes). In addition, Megan mentions that the ''Star Wars'' series had "script work by {{w|Billie Lourd}}'s mom", referring to {{w|Carrie Fisher}}, who [https://www.slashfilm.com/548436/carrie-fisher-script-doctor/ contributed uncredited script-doctoring work] to the ''Star Wars'' franchise. However, Fisher is more closely associated with ''Star Wars'' for having played the major role of {{w|Princess Leia Organa}} in six films in the series.

''Ghostwriter'' was previously featured in [[130: Julia Stiles]], which described a scene from the show as "the best thing ever to appear on TV".

2443: Immune Response

| titletext = I don't care whether you win or lose, as long as you have-- ...okay, sorry, I'm being reminded I very much care whether you win or lose. I need you to win, that's very important.
}}

==Explanation==
This is another comic in a [[:Category:COVID-19|series]] related to the {{w|COVID-19 pandemic}}.

As with a [[2287: Pathogen Resistance|number of previous strips]], [[Randall]] has a tendency to anthropomorphize both pathogens and the immune system, [[2425: mRNA Vaccine|envisioning the process of infection and immune response as an epic battle]]. In this case, he treats his immune system as he would a child trying to accomplish something difficult, and worries about its emotional reaction.

The [[:Category:COVID-19 vaccine|COVID-19 vaccine]]s (like all viral inoculations) work by introducing viral proteins into the body, causing the immune system to react as if the actual virus were present, creating the antibodies to fight it. As a result, if the actual virus is introduced, the immune system will have the capacity to quickly eliminate it.

In this comic, [[Cueball]] has just received the COVID-19 vaccine and anthropomorphizes this process. He worries that his immune system is "freaking out", as the vaccine causes the body to 'think' it's under attack and respond as it would to a deadly threat. Cueball accordingly tries to reassure his immune system that the threat isn't real. However, [[Megan]] reminds him that the "panic" is the entire point, as that's what causes the body to build defenses, which will allow it to handle the real virus. Cueball then switches tactics, melodramatically announcing that the virus is about to kill him, and encouraging his "heroic immune cells" to save the day. The joke is that the basic elements of their response is accurate: the vaccine is essentially a ruse intended to "trick" the immune system into developing antibodies. However, the immune system obviously lacks a separate consciousness, and can neither hear nor understand their comments,{{Citation needed}} making both reassurance and encouragement entirely moot.

In the title text, Cueball continues to treat his immune system like a conscious entity. Specifically, all of his communications sound like a parent, or other adult, trying to encourage a child who was trying to win a game: giving it a pep talk about how he doesn't care if it wins or loses as long as it has fun. This is a common refrain when parents or other adults try to reassure children in contexts where victory isn't especially important, and where enjoyment is the real goal. Cueball then remembers that this particular event is much more consequential. If his immune system were to 'lose' to the vaccine, that would presumably mean it was incapable of responding properly to the viral threat, meaning he'd be in serious risk of death if he contracted the actual virus. As a result, he corrects himself and states that winning, in this case, is "very important".

That is, if you take the union of any collection of topological spaces in the collection (even uncountably many), or the smash product of them, the result will also be in that collection. This is apparently important because the sets can't be isomorphic (one cannot be rearranged to be exactly the other) [https://mathoverflow.net/questions/196084/counterexample-for-associativity-of-smash-product] For use in a serif font|| Spider caught with a cup and index card || Spiders or other bugs found within someone's house or workspace may be caught with a glass and something flat, often a card or a magazine, to be released outside.

2605: Taylor Series

2022-04-12T06:40:17Z

{{incomplete|Created by THE MACLAURIN SERIES EVALUATED AT NON-ZERO X - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In mathematics, a {{w|Taylor series}} of a function is an infinite sum of terms that are expressed as the function's derivatives. Their expressions, usually referred to as "expansions," continue indefinitely without end. Taylor series are useful for approximating {{w|Irrational number|irrational}} values, {{w|Machin-like formula|such as π}}, to make them easier to integrate or otherwise manipulate with calculus.[https://www.mathsisfun.com/algebra/taylor-series.html] However, because they involve difficult calculus operations, and can be annoyingly tedious to {{w|Numerical analysis|calculate by hand}}, they are often not loved by math students.

Miss Lenhart appears to be teaching a class about how to use a Taylor series. She has explained what one is, and how it is used. She presumes her students want to keep learning about the series, in that they "wish it would never end." She then says "Good news!" because the Taylor series does not end, with each term smaller than the last. The cartoon's humor is based on contrasting the idea of wishing the series would never end, which is ordinarily said about long-running sequences of enjoyable events, with the infinite nature of the Taylor series, which is probably not appreciated by her students struggling to understand why the sums converge to the resulting value.

The title text is a reference to the common practice among physicists and engineers of abbreviating the Taylor series to only the first few terms, typically one or two, in order to simplify the mathematics of their models. The title text is also a pun on the use of the word "series" to refer to a television program. It equates each term in the mathematical series to a television season, suggesting that only the first term is useful. It makes fun on the common sentiment on bad series by saying that "The series should have been cancelled after the first season", replacing "season" with "term". It could also reference the "term" of US President {{w|Zachary Taylor}}, who died after serving only fifteen months in office, or the political career of {{w|Charles_Taylor_(Liberian_politician)|Charles Taylor}}, whose first term ended in civil war and exile.

Non-mathematician here: what I don't get (and would appreciate having explained) is why he chose this specific instance of an {{w|Series_(mathematics)|infinite series}}. Is there something special about a Taylor series that makes it work best for this joke? Some deeper pun here that "Taylor Series" brings, over just using "(Laurent|Fourier|Dirichlet|Infinite) series" or even "Zeno's Paradox"? --[[Special:Contributions/172.69.69.182|172.69.69.182]] 19:44, 11 April 2022 (UTC)

:Taylor serie is approximation of arbitrary function. Fourier serie is also approximation of arbitrary function, although in different way. Those others are something completely different, though. For example, Taylor serie is not DEFINED as infinite - it just usually is. Saying that Laurent series is infinite is like, well, sure it is, it's defined that way, saying that about Taylor series approximating specific function is actually nontrivial statement. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:36, 12 April 2022 (UTC)

DuckDuckGo's search on "taylor series expansion taken to extremes" is remarkably unsatisfying, the first result being https://www.mathsisfun.com/algebra/taylor-series.html which nonetheless may be of use in the explanation.

2605: Taylor Series

In mathematics, the {{w|Taylor series}} of a function is an infinite sum of terms that are expressed as the function's derivatives. Their expressions, usually referred to as "expansions," continue indefinitely without end. Taylor series are useful for approximating {{w|Irrational number|irrational}} values, {{w|Machin-like formula|such as π}}, to make them easier to integrate or otherwise manipulate with calculus.[https://www.mathsisfun.com/algebra/taylor-series.html] However, because they involve difficult calculus operations, and can be annoyingly tedious to {{w|Numerical analysis|calculate by hand}}, they are often not loved by math students.

Miss Lenhart appears to be teaching a class about how to use a Taylor series. She has explained what one is, and how it is used. She presumes her students want to keep learning about the Taylor series; that they "wish it would never end." She then says "Good news!" because the Taylor series does not end, with each term smaller than the last. The cartoon's humor is based on wishing the series would never end, which is ordinarily said about long-running sequences of enjoyable events, in contrast to the infinite nature of the Taylor series, which is almost certainly not appreciated by her students struggling to understand why the sequence of sums converge to the intended value.

The title text is a reference to the common practice among physicists and engineers of abbreviating the Taylor series to only the first few terms, typically one or two, in order to simplify the mathematics of their models. The title text is also a pun on the use of the word "series" to refer to a television program. It equates each term in the mathematical series to a television season, suggesting that only the first term is useful. It makes fun on the common sentiment on bad series by saying that "The series should have been cancelled after the first season", replacing "season" with "term". It could also reference the "term" of US President {{w|Zachary Taylor}}, who died after serving only fifteen months in office, or the political career of {{w|Charles_Taylor_(Liberian_politician)|Charles Taylor}}, whose first term ended in civil war and exile.
