&lt;br /&gt;
[[File:Konigsberg bridges.png|frame|right|{{w|Königsberg}}, Prussia in Euler's time, showing the Pregel river and its seven bridges.]]&lt;br /&gt;
&lt;br /&gt;
This comic is about the {{w|Seven Bridges of Königsberg}} (present day {{w|Kaliningrad}}), a seminal {{w|graph theory}} problem solved by the famous mathematician {{w|Leonhard Euler}}.[https://www.maa.org/press/periodicals/convergence/leonard-eulers-solution-to-the-konigsberg-bridge-problem] The problem was whether a path through the city crossing each of the seven bridges just once exists, without crossing the river forks any other way. In 1736, Euler proved that there is no such path. This result is considered to be the first theorem of graph theory and the first proof in the theory of networks[http://www-personal.umich.edu/~mejn/courses/2004/cscs535/review.pdf] — a subject now generally regarded as a branch of {{w|combinatorics}} — and presaged the development of {{w|topology}}. Combinatorial problems of other types had been considered since antiquity. {{w|Graph (discrete mathematics)|Graphs}} are a data structure common in many algorithmic problems in computer science.&lt;br /&gt;
&lt;br /&gt;
[[Cueball]] attempts to cheat on the final exam in his algorithms class by traveling back in time to commission the construction of an eighth bridge before Euler could learn of the problem, allowing a trivial solution that would remove the rationale for further analysis. He hopes that this would alter his present-day timeline in such a way that the test becomes easier because graph theory might never have been developed.&lt;br /&gt;
&lt;br /&gt;
With the addition of the eighth bridge, it becomes possible to cross each bridge exactly once, starting at the north bank and ending on the larger eastern island, or vice-versa. However, there is still no way to traverse each bridge exactly once and return to the starting point, because the altered graph would have an {{w|Eulerian trail|Euler trail}} but not an Euler cycle. Thus the problem might still have been interesting to Euler. (Adding a ninth bridge connecting the north bank to the east island, or constructing the eighth bridge between the eastern and central islands rather than the location provided, would render the problem completely trivial.) We can't say whether Euler or others would have developed graph theory anyway, or whether Cueball's exam would have been any easier, more difficult, or similar.&lt;br /&gt;
&lt;br /&gt;
An alternative modification allowing an easy solution is to remove bridges. During World War II, two bridges to the central island connecting it to the north and south banks were destroyed by bombing, so today there is an Eulerian trail across the five remaining bridges.&lt;br /&gt;
&lt;br /&gt;
The title text alludes to the fact that ordinary {{w|aluminum foil}}, which was not commercially available until 1911, would have been a tremendously valuable curiosity in the 18th century, which didn't even have {{w|tin foil}}. Aluminum was a highly priced metal before the 1880s when inexpensive methods were developed to refine it. The {{w|Washington Monument}} was constructed with a tip made of pure aluminum due to its value and conductive capacity. Aluminum had not been extracted in its pure form at the time of Euler, and was known only in compounds such as {{w|alum}}, so the metal would have been unique and exotic.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by a MONKEY **. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon. *BOT}}&lt;br /&gt;
In text messages, asterisks are commonly used to denote a correction of some error in an earlier text. The messenger ([[Randall]]) corrects four such inaccuracies.&lt;br /&gt;
The message, if the corrections were to be taken in order, might read &amp;quot;I'm gonna eat 3 AM on the couch at pizza.&amp;quot; The typical reader should be sharp enough to know that it should read &amp;quot;I'm gonna eat a pizza on the couch at 3 AM.&amp;quot; Randall finds this remarkable.&lt;br /&gt;
&lt;br /&gt;
Taken one at a time, it appears the reader would have the following sentences in their head:&lt;br /&gt;
:I'm gonna ride a horse on the beach at dawn (sounds adventurous and sporty)&lt;br /&gt;
:I'm gonna '''eat''' a horse on the beach at dawn (a figure of speech?)&lt;br /&gt;
:I'm gonna eat a horse on the beach at '''3AM''' (occultish?)&lt;br /&gt;
:I'm gonna eat a horse on the '''couch''' at 3AM (lazily occultish, or worse?)&lt;br /&gt;
:I'm gonna eat a '''pizza''' on the couch at 3AM (not too odd, but very slobbish)&lt;br /&gt;
&lt;br /&gt;
In the title text, Randall says that he likes to make his text recipient have to guess where his correction should be, and uses the following sentence and correction:&lt;br /&gt;
:&amp;quot;I'd love to meet up, maybe in a few days? Next week is looking pretty empty.&amp;quot;&lt;br /&gt;
: *witchcraft&lt;br /&gt;
The trick here is trying to figure out which word(s) should be replaced by &amp;quot;witchcraft&amp;quot;. Possible solutions suggested in the comments are: &lt;br /&gt;
: &amp;quot;I'd love to meet up, maybe in a few days? '''Witchcraft''' week is looking pretty empty.&amp;quot;&lt;br /&gt;
: &amp;quot;I'd love to '''witchcraft''', maybe in a few days? Next week is looking pretty empty.&amp;quot;&lt;br /&gt;
: &amp;quot;I'd love to meet up, '''witchcraft''' in a few days? Next week is looking pretty empty.&amp;quot;&lt;br /&gt;
: &amp;quot;I'd love to meet up, maybe '''witchcraft''' a few days? Next week is looking pretty empty.&amp;quot;&lt;br /&gt;

As it turns out, Rule 110 seems to be a ''really bad'' way to simulate a universe- you would be much better off using a {{w|Tag_system|Cyclic tag system}}, since Rule 110 takes dozens of generations and potentially hundreds of cells to simulate one step in such a system, or a more sophisticated cellular automaton, such as {{w|Wireworld.}} --[[User:Someone Else 37|Someone Else 37]] ([[User talk:Someone Else 37|talk]]) 05:12, 9 March 2014 (UTC)&lt;br /&gt;

The diagram to the right of the Epitaph of Stevinus looks like a system of coupled pendula, often used in math physics courses to illustrate Lagrangian mechanics. Also may relate to elasticity theory. See for example here: http://demonstrations.wolfram.com/ThreePendulumsConnectedByTwoSprings.

:The &amp;quot;diagram to the right of the Epitaph of Stevinus&amp;quot;, also described as &amp;quot;A weird diagram with lines in it&amp;quot;, or &amp;quot;partitioning of phase space into fundamental cells&amp;quot;, or &amp;quot; system of coupled pendula, often used in math physics courses to illustrate Lagrangian mechanics&amp;quot;, can be described more literally: ''There is are two horizontal rulers with divisions 13 pixels apart and 17 pixels apart, respectively; and diagonal lines showing the correspondence between the first four markings of the upper ruler with those on the lower. The intervals seem to be labeled.'' Returning to speculation, I think this suggests an illustration of '''Length contraction (Lorentz coordinate transformation) in Special Relativity'''.  [[User:Mrob27|Mrob27]] ([[User talk:Mrob27|talk]]) 20:22, 28 November 2014 (UTC)&lt;br /&gt;
:: That seems highly unlikely due to the top labels on this graph. In your explanation they can’t represent anything relevant.

I don't think Randall put enough thought into those tiny squiggles for us to be able to use pixel-counting as a hint to which labels interpretation is more likely… but what of it? We can make up labels that fit any interpretation. I did say &amp;quot;Length contraction (Lorentz...)&amp;quot; was just ''speculation''. I do like the &amp;quot;four pendulums coupled by springs&amp;quot; idea, though the horizontals look too ruler-like to me.

:Also, I'd like to point out that all three diagrams unify the theme of &amp;quot;working out the kinks in quantum mechanics and relativity&amp;quot;: The first illustrates a region of the bell curve where a particle might occasionally fall if it is about to exhibit quantum tunneling; the second relates to perpetual motion, thus hinting at general questions like &amp;quot;does quantum mechanics or relativity allow us to violate the laws of thermodynamics in any way?&amp;quot;, and the third is from special relativity.

:: Having studied (and knowing the fundamentals about what profile is needed to create a device that performs quantum tunneling) I have never seen this graph as a representation of this, and frankly it makes no sense. If this diagram was an energy band the hole or electron would have no need to tunnel to go up or down the energy band as it is a gradual slope.  If a device had a profile like this, it would not result in a significant number of tunneling events, especially at the positions that are marked on the diagram. For this to occur there would need to be a peak between the two points, and the points would need to be at similar heights (energy levels).

::: Yes, you're right: all we know is that it's a bell curve (normal distribution), and mentioning &amp;quot;tunneling&amp;quot; might make the reader think we were saying it is a potential function. I was reading a bit much into it. Why are there two vertical dotted lines at roughly +σ and +2σ? I thought they indicated a &amp;quot;range&amp;quot; as if the graph were illustrating some discussion of things that fall within that range.

is randall not assuming that his universe (and by implication ours) is finite? if not, one iteration of the machine would still take infinite time. --[[Special:Contributions/141.101.98.201|141.101.98.201]] 12:42, 26 November 2014 (UTC)&lt;br /&gt;
: I think it's good enough to assume that the universe is finite, but really really huge. Hypothesizing that adding one particle to the model requires twice as many cells in the cellular automaton, that means that Cueball's cellular automata rows could be about 2^(10^80) cells long, allowing simulation of a physics system containing 10^80 particles. Of course, each planck-time would require 2^(10^80) steps of simulation in the CA. If 10^80 isn't big enough for you, then just make it 10^1000 or Graham's number, or anything finite.

:: Don't forget that Rule 110 has 000 -&amp;gt; 0. Cueball can just add columns on either side as his universe expands, consequently taking more and more time to compute steps as the number of columns increases. {{unsigned ip|108.162.216.42}}&lt;br /&gt;

I don't understand how it's possible to simulate a universe this way. Assuming that quantum mechanics is correct, and some forms of particle decay are truly random, wouldn't it be impossible to simulate this with a purely deterministic system? [[User:KingSupernova|KingSupernova]] ([[User talk:KingSupernova|talk]]) 15:30, 1 December 2015 (UTC)&lt;br /&gt;
: The universe Cueball is simulating would have to conform to [[wikipedia:Digital physics|digital physics]]. I can't speak about the fine points of quantum mechanics, but observably random events in a simulated universe could be the result of a pseudorandom number generator with a very large state.

This is definitely my favorite comic. I just really love it - I wish there was a book or something about it that was more in depth. --[[Special:Contributions/108.162.219.5|108.162.219.5]] 14:32, 5 June 2016 (UTC)&lt;br /&gt;
:Yeah. Wow. Just... Wow. I would be so interested if this were somehow true. I just wish he could occasionally figure out how to mess with our retinas by spontaneously flipping bits in order to make us see a representation of him. That would be awesome, right? If I can make my own universe, well... I would do that. Also, I love this guy, real or not.

==Explanation==&lt;br /&gt;
{{incomplete|Created by TECHNICAL DIFFICULTIES. The hint table needs to be completed. The mechanics should be explained more in-depth, if possible, screenshots of the hints, items in inventory, items-placing mechanics etc. should be added.}}&lt;br /&gt;
&lt;br /&gt;
This was the 2020 April 1st comic. It is a large image, of which only part is visible, but can be dragged around. This space acts as a shared virtual sandbox where viewers can interact.  &amp;quot;Items&amp;quot; (small, often humorous images) could be collected from other comics and then placed in this image by viewers. The collection then updated for all viewers in real-time. Multiples of the same item are often seen. &lt;br /&gt;
&lt;br /&gt;
There is a &amp;quot;backpack&amp;quot; at the bottom, similar to backpacks in video games containing items collected by the player. As hinted by the title text, items could be found by visiting different XKCD comics/pages. Randomly, some pages would have a treasure chest which contained the sticker related to the page. The hint would refer to the page which currently had a chest.&lt;br /&gt;
&lt;br /&gt;
The sticker images can be seen at &amp;lt;nowiki&amp;gt;https://xkcd.com/2288/collectors/static/loot/loot_&amp;lt;/nowiki&amp;gt;'''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 &amp;lt;nowiki&amp;gt;https://xkcd.com/2288/collectors/static/loot/element-&amp;lt;/nowiki&amp;gt;'''XX'''.png, where XX is the element, and text loot at &amp;lt;nowiki&amp;gt;https://xkcd.com/2288/collectors/static/loot/loot-words-&amp;lt;/nowiki&amp;gt;'''X'''.png, where X is the sentence.&lt;br /&gt;
&lt;br /&gt;
As of April 5, chests are no longer dropped. &lt;br /&gt;

==Trivia==&lt;br /&gt;
* This comic is the 2020 April Fools comic and was supposed to be released Wednesday, April 1st, but did not go live until Friday, April 3. (Friday's comic, [[2289: Scenario 4]], was published a day later for a [[2289: Scenario 4#Trivia|very rare Saturday release]].) However, the message below was displayed on the top of the page from Wednesday until the comic finally went live:&lt;br /&gt;
&amp;lt;blockquote&amp;gt;&lt;br /&gt;
Note: For technical reasons Wednesday's comic will be posted Thursday instead. Apologies for the delay!&lt;br /&gt;
&amp;lt;/blockquote&amp;gt;&lt;br /&gt;
* This is one of the few comics released four days after the previous one. The last time this occurred was [[2224: Software Updates]]. &lt;br /&gt;
* Placement is limited to 10,000 horizontal units and 5,000 vertical units from the origin. Users received no messages if they try placing something outside the boundary, with a silent fail with the object not being placed.&lt;br /&gt;
* Coordinates are relative to the bottom left corner of the canvas. As the default coordinates are (-370,-277) and the origin is in the center, the displayed portion of the canvas can be found to be twice this in magnitude, 740 x 544 units.&lt;br /&gt;
* The comic contains 32993 separate images.&lt;br /&gt;
* The most common image is loot-30.png, which appears 2576 times.&lt;br /&gt;

When looking at viruses, I consider them made of the things of life (proteins, lipids, nucleic acids), but are not actually alive as they have no metabolism and can not reproduce on their own; they need to co-opt the protein production facility of truly living cells in order to reproduce.  Without a host, they just sit there (or maybe blow around on the wind).  Also without metabolism, they can not starve to death, like bacteria and other single-cell organisms that get into the wrong environment.

==Explanation==&lt;br /&gt;
{{incomplete|Created by a GLIDER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
{{w|John Horton Conway|John Conway}}, an English mathematician, passed away of {{w|COVID-19}} two days before this comic's release. As such, [[Randall]] created this memorial comic. One of Conway's most famous creations was {{w|Conway's Game of Life}}, which consists of an infinite square grid and rules of how it changes over time. Although the rules are simple, the system supports immense complexity.&lt;br /&gt;
&lt;br /&gt;
The Game of Life proceeds in a series of generations, with ''live'' and ''dead'' cells in each generation obeying these rules:&lt;br /&gt;
*Any live cell (dark colored) with two or three live neighbors survives to the next generation.&lt;br /&gt;
*Any dead cell (white) with three live neighbors becomes a live cell in the next generation.&lt;br /&gt;
*All other live cells die in the next generation. Similarly, all other dead cells stay dead.&lt;br /&gt;
&lt;br /&gt;
This comic begins with the shape of a stick figure as the starting configuration, which then evolves according to the rules of the Game of Life. The pattern breaks into three parts, two of which stay at the same level as the original figure's feet before rapidly melting away, and a third (called a &amp;quot;glider&amp;quot;) that ascends up and to the right. Randall may be suggesting a soul breaking away from the rapidly disintegrating corporeal remains here.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
{{incomplete transcript|Do NOT delete this tag too soon.}}&lt;br /&gt;
:[A pixelated image of a stick figure. The image is animated, with the pixels changing according to the rules of Conway's Game of Life. The figure splits into two groups, one of which dissipates. The other becomes a 'glider' and moves off to the top-right corner of the image before repeating the animation.]&lt;br /&gt;

This is really very impressive.  The design of the stick figure to allow it to release a glider that ascends upwards (the &amp;quot;soul&amp;quot; rising to &amp;quot;heaven&amp;quot; or whatever) with the body decaying - that's a hard thing to get right using just the Game of Life rules.

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a Steph Curry. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
The comic is about the [https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201920200SB206 California Fair Pay to Play act], which was signed into law on September 30, 2019. It gives college athletes the rights to their name and face for financial gain, in contrast to NCAA rules which require that athletes be unpaid.&lt;br /&gt;
&lt;br /&gt;
In this comic, Cueball claims that all members of his college basketball team changed their name to Steph Curry, after the NBA Player of the same name. In particular, one player copied the name from the NBA player, then another member of the team copied the name from that player, and so on.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
This process is called &amp;quot;Currying&amp;quot;, a play on both the name &amp;quot;Curry&amp;quot; used here, as well as the mathematical procedure called {{w|currying}}, named after mathematician Haskell Curry, wherein a multivariable function is broken down into a sequence of single-variable functions, each of which outputs a new function until the final variable is consumed. For example, the function f(x,y,z) can be curried into f(x)(y)(z), where f is a function that consumes x and produces a function f(x), which in turn consumes y, yielding the function f(x)(y), and that in turn is a function f(x)(y) which consumes the parameter z to finally produce f(x)(y)(z), which is equal to the original f(x,y,z). This is not commonly used in most areas of math except for foundational logic, but it is widely used in functional programming.&lt;br /&gt;
&lt;br /&gt;
White Hat’s question regarding the form ‘''Stephs Curry''’ is referring to the pluralization of phrases where a noun is followed by a modifier of some sort, such as ''attorneys general'', ''parts unknown'', ''heirs apparent'', ''mothers-in-law'', and so on. In these cases, plurals are formed by pluralizing the noun parts of the phrases; however, some of these are rare or foreign enough that speakers of English don't always identify them correctly and pluralize the last word instead, e.g. *''attorney generals''.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The title text is a computer science joke, saying that their signature play is the &amp;quot;three-point combinator&amp;quot;, a joke on the {{w|Three-point_play|three-point play}} in basketball, and Y Combinator, which is a {{w|Fixed-point_combinator#Y_combinator|fixed-point combinator}} introduced by Haskell Curry, recursive ([https://www.urbandictionary.com/define.php?term=recursion see: recursion]) and does not halt (see: the {{w|Halting_problem|Halting Problem}}). &amp;quot;Signature play&amp;quot; may also be a play on words, as currying transforms a {{w|Type_signature#Method_signature|method signature}}.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball, Ponytail and White Hat are having a conversation. Ponytail is checking her phone.]&lt;br /&gt;
:Ponytail: Oh, huh. California passed a law giving college athletes full rights to their names and images.&lt;br /&gt;
:White Hat: Good, I think?&lt;br /&gt;
&lt;br /&gt;
:[Cueball holds his hand up in a fist, while Ponytail, holding her phone down, and White hat looks at him.]&lt;br /&gt;
:Cueball: That's nothing. '''''Our''''' state gave college players rights to use the names and images of '''''any''''' California athletes.&lt;br /&gt;
:Ponytail: It did not.&lt;br /&gt;
&lt;br /&gt;
:[In a frame-less panel Cueball holds his hands out, Ponytails phone is gone and White Hat puts a hand to his chin.]&lt;br /&gt;
:Cueball: Sure it did!&lt;br /&gt;
:Cueball: That's how our school fielded a basketball team made up entirely of Steph Currys.&lt;br /&gt;
:White Hat: Or is the plural &amp;quot;Stephs Curry&amp;quot;?&lt;br /&gt;
&lt;br /&gt;
:[Cueball holds both hands up in front of him. Ponytail has her arms down but she is balling her hands into fists.]&lt;br /&gt;
:Cueball: They didn't all copy the original Steph, though. One player got the rights to his name, then the next player got it from them, and so on.&lt;br /&gt;
:Cueball: This process is known as &amp;quot;currying&amp;quot;.&lt;br /&gt;
