162.158.91.155: There are 20 comics now

*These comics are inspired by the {{w|2019–20 coronavirus pandemic|2019-20 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}} which results in the {{w|coronavirus disease 2019}}, COVID-19 for short.
*The fifth of these, [[2279: Symptoms]], came out on March 11, 2020, the day when the outbreak was declared a world wide {{w|pandemic}}.
*The first comic about COVID-19 came out as the first comic in March.
**19 comics in a row were related to this pandemic, except the [[:Category:April fools' comics|April fool's comic]], [[2288: Collector's Edition]], which was probably already in the making when the first comic came out (and even if so it's release was delayed until April 3rd). (So 19 out of 20, and all of the comics in March 2020 was about COVID-19. Many find pleasure in the fact that it was 19 comics on COVID-19!)
***The first comic that was not clearly about COVID-19 was [[2295: Garbage Math]].
***Although the garbage input may very well be data on COVID-19, there was no clear reference to the pandemic. Thus ending the streak!

This comic is another comic in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}.

Recently, because of the coronavirus, many people are forced to stay home in quarantine. Something that many people are doing with their time is baking sourdough bread with {{w|sourdough starter}}s. In this comic, a joke is made that coronavirus is actually an organism which lives symbiotically with yeast in sourdough starters, and leads a parasitic lifestyle inside of humans, sourdough starter, and bread.

{{w|Parasite}}s are organisms that usually cannot survive without the presence of another host organism. Many parasites have distinct cycles in order to propagate themselves, which are indirect in nature. For example, {{w|Toxoplasma gondii}} will first go through mice, affecting their nervous systems and making them extremely reckless, in order to get the system caught and eaten by a cat, which is the target host for the parasite. It has been said that the parasite may also infect other animals too, with unintended side effects... To this end, Randall proposes that the coronavirus is possibly one such parasite, using humans as a vector in order to infect yeast. Since many humans (bakers) work with yeast a lot, that is a convoluted, though not entirely impossible, way for the virus to spread to its host.

The word symbiont suggests symbiosis, which is not a parasitic relationship, but rather one of mutual benefit. This adds to the convolution, since although we usually regard symbiosis as good, as opposed to parasitism, the virus causes a lot of harm in another species to do it.

2284: Sabotage

2020-04-17T20:51:04Z

162.158.91.155: Undo revision 190840 by 172.68.143.126 (talk)

{{comic
| number = 2284
| date = March 23, 2020
| title = Sabotage
| image = sabotage.png
| titletext = So excited to see everyone after my luxury cruise home from the World Handshake Championships!
}}

==Explanation==
This comic is the tenth comic in a row in a [[:Category:COVID-19|series of comics]] about the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} - {{w|SARS-CoV-2}}.

In the wake of the virus, the advice from many professionals in the United States is to avoid public gatherings to slow the spread of the virus and "flatten the curve".

In this comic, some group of people (we're not told who) are planning a public event, which is very much contrary to the widespread professional advice, and is said to put everyone at risk by accelerating the spread of the virus in the general population. In an effort to sabotage this event by deterring people from attending, [[Cueball]] applies reverse psychology, pretending to be enthusiastically planning various activities at the gathering that most people would go out of their way to avoid: a wild skunk petting zoo, which would most likely result in everyone getting heavily sprayed with violently foul-smelling skunk scent that wild skunks use to drive away predators; and {{w|karaoke}} featuring the song "{{w|Baby Shark}}", which is a song for small children that is generally considered annoying to adults, made even more direly annoying in this case by being spoken rather than sung.

In the title text, Cueball has stepped up his game from merely threatening to spoil everyone's fun to making them fear that they might get infected. He claims to have attended the "World Handshake Championships", which presumably would involve shaking hands with as many people as possible; this would facilitate the spread of diseases such as COVID-19. He furthermore claims to have traveled home from the championship via a cruise ship, which may also cause concern because cruise ships are known for their densely populated environments and lack of extensive medical facilities making prevention and treatment of infections very difficult or impossible. Cruise ships have been a recent topic of interest in relation to SARS CoV-2 due to many people being stranded at sea with infected patients because of COVID-19 outbreaks on board.

==Transcript==

:[Cueball is seated at a desk, typing on a laptop. The top half of the image is the text he is typing in a reply message:]
:"I see you're still getting together today! I'll be there, doing my spoken-word ''Baby Shark'' karaoke all evening.
:We'll also be setting up a petting zoo for the kids. We've spent all week trapping wild skunks!"
:[Below the text is a white-on-green "reply" button.]

:In the coronavirus era, desperate times call for desperate measures.

2288: Collector's Edition

2020-04-03T21:13:18Z

162.158.91.155: /* Hints */ I found the "Cape Town Chukota" crater and placed it here: https://xkcd.com/#-6280,-357

{{comic
| number = 2288
| date = April 3, 2020
| title = Collectors Edition

| titletext = I'm sure you can find some suitable worldbuilding material if you scavenge through the archives.

==Explanation==
{{incomplete|Created by TECHNICAL DIFFICULTIES. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This is an April 1st comic. It is a large image, of which only part is visible, but it can be dragged around. This Space acts as a virtual common sandbox where viewers can interact. "Items" (small, often humorous images) can be 'collected' from other comics and then placed in this image by viewers. The collection then updates for all viewers in real-time. Multiples of the same item are often seen.

There is a "backpack" at the bottom, similar to "backpacks" in video games containing items collected by the player. Items can be found by visiting different XKCD comics/pages. Randomly, some pages will have a treasure chest which will contain the sticker related to the page. It is believed that the hint represents what page currently has a chest.

The sticker images can be seen at https://xkcd.com/2288/collectors/static/loot/loot_XXX.png, where XXX is a number from 001-253. Additionally, some images can be found at custom URLs, for example the periodic elements can be found at https://xkcd.com/2288/collectors/static/loot/element-XX.png, where XX is the element, and text loot at https://xkcd.com/2288/collectors/static/loot/loot-words-X.png, where X is the sentence.

Talk:2287: Pathogen Resistance

2020-03-31T08:55:35Z

162.158.91.155:

Note that the title text says "not not" -- meaning we're both trapped in here together [[User:John.Adriaan|John.Adriaan]] ([[User talk:John.Adriaan|talk]]) 04:38, 31 March 2020 (UTC)

Do bacteriophages "afflict" humanity? To my knowledge, they only infect bacteria and are even considered a possible future alternative to antibiotics by some. What is up with them being represented here? 09:12, 31 March 2020 (UTC)

: Yeah, bacteriophage is just wrong here, it's a generic virus. This type of virus is depicted on the bacteriophage wikipedia page but viruses that affect humans can have that shape also. [[Special:Contributions/172.68.51.94|172.68.51.94]]

: There are no known human viruses of that shape (source: I'm a biologist), so this seems like more of a mistake on Randall's side (albeit an odd one for him to make, so perhaps somehow deliberate?). [[Special:Contributions/162.158.91.155|162.158.91.155]] 08:55, 31 March 2020 (UTC)

Don’t worry, pathogens! All is not lost. There will always be some humans whose brains don’t work very well, who will buy into ideas like “vaccines cause autism”, or “faith healing”, or “natural remedies”, or “Trump is always right”. You’ll still have hosts. [[User:Tualha|Tualha]] ([[User talk:Tualha|talk]]) 07:27, 31 March 2020 (UTC)

Bacteriophages only infect bacteria and some kinds of Archaea, not humans, so the explanation is slightly wrong. They are probably the prettiest and easiest to recognise viral shape though, which is why they are so commonly used in cartoons and illustrations.[[User:Phil|Phil]] ([[User talk:Phil|talk]]) 08:29, 31 March 2020 (UTC)
:I am just as much a hobby-virologist as anybody else suddenly is, but I have no clue what you are talking about. I don't even know which of the 3 shapes you mean. So please edit the explanation yourself if you see, that it is wrong. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 08:37, 31 March 2020 (UTC)

1102: Fastest-Growing

2020-03-23T15:51:48Z

162.158.91.155: /* Explanation */

{{comic
| number = 1102
| date = August 31, 2012
| title = Fastest-Growing
| image = fastest_growing.png
| titletext = I lead a small but extraordinarily persuasive religion whose only members are door-to-door proselytizers from other faiths.
}}

==Explanation==
Using percentage of growth can be misleading for gauging the importance or popularity of something. If you add only 4 members to an existing group of 2, you would have achieved a growth of 200 percent.

In the case portrayed in this comic the claim appears to be that the other person's religion grew by 85%. [[Black Hat]] attempts humorously to show the flaw in using that statistic by growing his group by 100% (therefore, presumably, first place), which he simply does by adding his friend [[Rob]] to his religion, and thus increasing his membership from 1 to 2. The other person then says that his religion has a significant number of members (and not just one or two), but Black Hat doesn't care and responds that he hopes they are all okay with being "in second place" since the main argument from the other guy was about being the fastest-growing.

The title text ponders the ironic idea of converting ''only'' the zealous door-to-door {{w|Proselytism|proselytizers}} to a very persuasive religion of one's own.

Another interpretation is that the title text could be another way that Black Hat could take the 'fastest-growing' claim out of context to make it meaningless. By composing his religion of the unwitting proselytizers of other faiths, he can claim the highest ratio of converts to current adherents. Note that the amount of people converted is often exaggerated by groups that try to spread a faith. Although the beliefs spread by his proselytizers vary widely, Black Hat is not concerned with what his so-called followers believe. Thus, he can claim the title of fastest-growing religion without having any value to his religion.

Various religions and groups encourage their members to actively recruit new followers, some even take this as their duty as a member of their religion. Such as the {{w|Mormon missionary}}.

Talk:2042: Rolle's Theorem

:I do not have the time to do it good, so here a suggestion: Would someone go to the wikipedia page of Rolle's theorem and add a "in popular culture" section? may be a first?

::Speaking of popular culture, there's a (moderately) well known Ballad of Rolle's theorem [https://www.youtube.com/watch?v=S0BXv90MlhA Balada o vete Rolleovej] ("moderately" meaning some people who studied at Faculty of mathematics in Bratislava might have heard (of) it) --[[User:Kventin|Kventin]] ([[User talk:Kventin|talk]]) 07:41, 7 September 2018 (UTC)

I feel like Euclid beat Randall to the punch here, a couple millennia. [[Special:Contributions/162.158.155.146|162.158.155.146]] 16:54, 5 September 2018 (UTC)

I don't see that Thales has proven Randall's theorem. Do not to be confused with {{w|Thales's theorem}}, that's about right angles. Maybe I'm blind or just dumb, but if so it has to be explained with more traceable background. I just believe that this diagonal is so trivial that even the ancient Greeks weren't engaged on a proof. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:38, 5 September 2018 (UTC)
* From {{w|Thales|Wikipedia}}: Other quotes from Proclus list more of Thales' mathematical achievements: "They say that Thales was the first to demonstrate that the circle is bisected by the diameter, the cause of the bisection being the unimpeded passage of the straight line through the centre."

'''Rolle's Theorem counterexample?'''

Isn't the TAN(x) function a counterexample to this? Starting at a given point, it rises to infinity, then returns from negative infinity to the same point without ever having a slope of zero. [[Special:Contributions/172.68.58.89|172.68.58.89]] 06:58, 6 September 2018 (UTC)
:TAN(x) isn't differentiable at pi/2, hence the theorem doesn't apply--[[Special:Contributions/162.158.92.40|162.158.92.40]] 07:48, 6 September 2018 (UTC)
::And tan(x) has a slope of 0 at pi, so even if it applied, it wouldn't prove it wrong. A better example would be 1/x, but still invalid. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 08:01, 6 September 2018 (UTC)
:::Nope: tan(x) has a slope of 1 at pi, and its slope is never less than 1. Of course, that doesn't make it a counterexample. Zetfr 09:17, 6 September 2018 (UTC)

'''Clueless Museum Visitor'''

The math in the comic is well explained, but shouldn't there be something about the "math equivalent of the clueless art museum visitor..." part? Zetfr 09:17, 6 September 2018 (UTC)
: Seconded, all the argument here is about math that isn't even *in* the comic, whereas the bit that confuses me is the cultural metaphor... [[Special:Contributions/162.158.154.235|162.158.154.235]] 07:16, 7 September 2018 (UTC)

Just so we're on the same page, while the proof of Rolle's theorem is not completely trivial, neither is it difficult by any means. Proving it seems to be a pretty common homework assignment in undergrad math classes, for example, so one might legitimately ask why it deserved to be named. Perhaps it's simply that it's old enough that the methods at the time were crappy, and so modern proofs are much easier. [[Special:Contributions/172.69.22.140|172.69.22.140]]
: It is named because it's a very important theorem in calculus, used to prove many other theorems or results. So when you need to prove something using this property, instead of re-demonstrating it or merely saying "it is well known that..." (which often raises alarm bells in the mind of the reader/corrector), all you have to do is reference Rolle's theorem.[[Special:Contributions/162.158.155.158|162.158.155.158]] 11:08, 6 September 2018 (UTC)
:: It could almost be called "Rolle's lemma". [[Special:Contributions/162.158.154.103|162.158.154.103]] 12:28, 6 September 2018 (UTC)
: When I am teaching Rolle's theorem, I always make it a point to draw the link to reals. Rolle's theorem fails when the output is complex valued. Then you can see for yourself how non-trivial this is. [[Special:Contributions/162.158.165.124|162.158.165.124]] 04:40, 7 September 2018 (UTC)

Has anyone else noted the irony of having a wiki page to explain a comic whose subject is how some things are self-evident? [[User:JamesCurran|JamesCurran]] ([[User talk:JamesCurran|talk]]) 20:13, 6 September 2018 (UTC)

Does the Kepler Conjecture actually belong on that list at the end? Most of the others are "derp" level intuitively obvious and/or essentially tautological on a very basic level, but the Kepler Conjecture couldn't actually be exhaustively proven until machine computation, nor is it intuitively definitive--if you've ever stacked round things into a box you've noticed that it feels like you're wasting a lot of space at the edges. So...? [[User:AtrumMessor|AtrumMessor]] ([[User talk:AtrumMessor|talk]]) 21:37, 6 September 2018 (UTC)
:I would also argue against most of the other examples. Neither the isoperimetric inequality nor the hairy ball theorem are obviously true and their proof is quite a bit more involved than the one of Rolle's theorem. The Jordan curve theorem sounds obvious but then the proof definitely isn't. The parallel postulate isn't even a theorem. The only real good example in the list is the pigeonhole principle.[[Special:Contributions/162.158.91.155|162.158.91.155]] 12:35, 7 September 2018 (UTC)

I also suggest that Fundamental Theorem of Calculus be removed from this list. Firstly, the beginner student, just introduced to derivatives and antiderivatives, will not easily see that antiderivatives are the same as finding areas under curves. Instead, it is only obvious upon hindsight, after instruction. More importantly, a restriction of the FTC to better-behaved spaces shows a far greater insanity: the restricted FTC is a consequence of generalised Stokes's theorem '''applied twice'''. This operation is so highly unintuitive, that one simply cannot claim that this is in any way, shape, or form, trivial. I think that trying to pretend that anything in beginning calculus is obvious to students is just going to alienate them rather than soothe their worries.

"Munroe's theorem" should definitely refer to the circle thing in the alt text {{unsigned ip|162.158.62.57}}

Since I'm half a mathematician, I did the math. I looked up Rolle's theorem and it uses the theorem of Weierstraß. I looked up the theorem of Weierstraß (better known as extreme value theorem) and it uses the theorem of Bolzano-Weierstraß. I looked up...why am I suddenly reminded of https://xkcd.com/609 ? :-) [[Special:Contributions/141.101.104.71|141.101.104.71]] 08:36, 7 September 2018 (UTC)
