172.68.133.217: /* Sorry */ modify apology

== Sorry ==

I want to repeat my apology for stepping on your [[2606: Weird Unicode Math Symbols]] table edits. You're absolutely right that adding columns basically has to be done in large edits, unless, for example, you insert empty cells first and then go back and add them one-by-one. Next time I will check the recent edit summaries in the history before jumping in to try to fix a broken table. [[Special:Contributions/172.70.206.213|172.70.206.213]] 08:09, 16 April 2022 (UTC)

|-
| U+2A7C || ⩼ || Greater-Than with Question Mark Above || Used in proofs to indicate a greater-than relation that should exist but hasn't been proven yet (non-rigorous) || Confused alligator || One metaphor used when teaching inequality signs in primary school is that the sign looks like an alligator mouth "eating" the larger number. Question marks are commonly used in cartoons to indicate confusion on the part of a character.
|-
| U+299E || ⦞ || Angle with S Inside || Plural for the angle symbol (∠) [https://www.quora.com/Unicode-How-is-the-s-in-triangle-glyph-used-in-mathematics][https://www.birdvilleschools.net/cms/lib2/TX01000797/Centricity/Domain/1114/Homework%20Helper%20Unit%203%20ch%209-10.pdf] rarely used || Snack || May look like a mouth eating an S, where the S symbolizes some snack food.

|-
| U+2A50 || ⩐ || Closed Union with Serifs and Smash Product || Indicates that a collection of topological spaces is {{w|Union-closed sets conjecture|closed}} when taking arbitrary unions and smash products. 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] || 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. The projecting lines of the smash product symbol resemble the legs of a spider. Confusingly, some fonts display this symbol with different numbers of "legs": eight, as a 45°-rotated hash symbol, or six as an asterisk.

|-
| U+232D || ⌭ || {{w|Cylindricity}} || A symbol used in geometric dimensioning and tolerancing (GD&T) to represent a parameter called "cylindricity" which describes the statistical deviation of an ensemble of surfaces from a reference cylinder. [https://cimquest-inc.com/metrology-minute-cylindricity/ example use] || Rolling dough between your hands to shape it into a ball || Looks like two flat hands (perhaps like stick-figure arms) rolling a ball between them. Rolling dough between one's hands to make it into a ball is an important step in making many kinds of pastry and bread.
|-
| U+2A13 || ⨓ || Line Integration with Semicircular Path Around Pole || Very rare symbol for half of a closed {{w|Contour integration|contour}} or {{w|Line integral|line}} integral which contains the {{w|Origin (mathematics)|origin}} in its interior. Contour integrals which circle the origin are very important in complex analysis. If such an integral were split into two parts, each could be represented by this symbol (which can be mistaken for ⨔, the integral not including the {{w|Zeros and poles|pole}}, with a wider and more complete arc around an offset dot.) [https://math.stackexchange.com/questions/2299363/where-is-the-%E2%A8%93-integral-symbol-defined]

[https://twitter.com/fermatslibrary/status/1308743505309822977 see also]
|| Mathematicians need to calm down || Each of the two symbols is specifically used to represent a kind of summation that is calculated completely differently from the other. Combining them could produce frustration for people unfamiliar with the usage. The comment given may make fun of mathematicians' tendency to form increasingly complex expressions in their work.

2519: Sloped Border

2021-09-23T06:59:30Z

{{comic
| number = 2519
| date = September 22, 2021
| title = Sloped Border
| image = sloped_border.png
| titletext = "The slope will be 74° at ground level." "Okay, I think we can hack together a ... wait, why did they specify ground level? It's 74° everywhere, right? ... Oh no, there's a whole section in the treaty labeled 'curvature.'"
}}

==Explanation==
{{incomplete|Created by a SUBSIDING GERRYMANDER - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
Every single country demarcate an {{w|international border}} with other countries. The borders are established through law, treaty or consensus. Establishing an international border is very necessary for customs, immigration and security checks. Some countries (like {{w|Cyprus}}) have established a {{w|buffer zone}} in place of an international border to gain additional protection during a conflict.

In this comic, Cueball and Blondie established a "sloped" international border through a treaty. Usually borders are perpendicular to the ground so that all the air(space) above the ground belongs to the same country. This is called {{w|Air sovereignty}}. Thus it suffice to define the border on the earth surface, as 2D lines. The precises definition is that a line from the center of the earth through the point of the border is drawn. Thus if the terrain is slopped then the border of the air sovereignty does form a slopped line with the terrain.

If the borders were sloped an airplane would need to know its precises height to decide which country's rules currently apply. With the help of the {{w|Global Positioning System}} this would be in principle possible, although the height information of GPS is less reliable. The mathematical computation for an angled air sovereignty is relatively straight-forward and could be expressed with a single line of code. However, if the line is curved (as indicated by the table of curvatures in the title text) the math may get very complicated.

==Transcript==
:[Cueball and Blondie are standing on a podium either for TV, or for the photo op when signing a treaty. They are holding a document together between them. In the background are two informational graphics.]
:Cueball: With this treaty, we are proud to announce the creation of the world's first '''''sloped''''' international border!

Talk:2515: Vaccine Research

2021-09-14T18:07:19Z

172.68.133.217:

Too bad White Hat and Randall didn't bother to research the other half of the question. YES, vaccines work to save lives. But There Ain't No Such Thing As A Free Lunch, and you need to research *both* sides of any question, not just the side you agree with.[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 12:52, 14 September 2021 (UTC)
: I really don't want this to turn into a long debate, but how do you know White Hat/Randall didn't find anything about the risks of vaccines? They never claim that and the fact that White Hat calls the vaccines "pretty good" instead of something like "perfect" would suggest he's aware of the downsides but considers the benefits to outweigh the risks. [[User:Bischoff|Bischoff]] ([[User talk:Bischoff|talk]]) 13:27, 14 September 2021 (UTC)

I don't trust the "scientists", so I decided to do my own research. Anyway, I need 5000 people for a double-blind clinical trial, so DM me if you know anyone interested.

==Explanation==
{{incomplete|Created by a LASER TOASTED MARSHMALLOW - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic claims that in every science lab, there exist some piece of equipment that sticks around less for being useful, and more because the scientists and technicians just think the device is really cool.

The comic presents a laser technician lab. While giving a tour [[Hairbun]] shows a spectrometer — a device that examines light emitted from samples, this one is likely a mass spectrometer which works by firing lasers at the sample to convert it into ions. Next she shows the "Nd:YAG" laser. "Nd:YAG" stands for [https://en.wikipedia.org/wiki/Nd:YAG_laser neodymium-doped yttrium aluminum garnet]; it is a lasing medium commonly used in lasers. Lastly she shows off a decommissioned laser not used in experiments, but rather for toasting marshmallows.

==Transcript==
{{incomplete transcript|Do NOT delete this tag too soon.}}

:Ponytail: The spectrometer is over here, the Nd:YAG lasers are over here,
:Ponytail: and in the corner is a laser that turned out not to be useful for us, but we keep it because it's fun to toast marshmallows with it.

{{w|Saturn's Hexagon}} is a cloud formation on Saturn centered on its north pole. Similar to Jupiter's {{w|Great Red Spot}}, Saturn's Hexagon has proven a persistent feature observed by multiple space probes. The cause was not known until recently, when data from the 2006-2009 {{w|Cassini–Huygens}} probe could be analyzed in depth. This finding was widely publicized in popular science media (see for example [https://www.sciencealert.com/astronomers-think-they-figured-out-how-saturn-s-giant-hexagonal-storm-could-have-formed]) and is related to how currents flow deep within Saturn's atmosphere.

Randall proposes an alternate explanation: it is the top of a {{w|Ball_(association_football)|soccer ball}}. Soccer Balls have been made in the shape of a {{w|truncated icosahedron}}, where faces alternate between regular hexagons and regular pentagons to achieve a more uniform roll, since 1968 when the design was introduced as the {{w|Adidas Telstar}}, a design now considered the "traditional" soccer ball.

BSBIT stands for Bachelor of Science in Business Information Technology [https://www.acronymfinder.com/Bachelor-of-Science-in-Business-Information-Technology-(BSBIT).html], a relatively new specialization where business majors learn programming techniques [https://vt.edu/academics/majors/business-information-technology.html]. It is probably used in the comic to imply that a graduate of this major came up with the soccer ball model listed in the presentation. (Of course, BSBIT also stands for "Big Soccer Ball In There".)

Soccer is the name given in the United States to {{w|association football}}, the form of football practiced in most of the world. Since the imperial system (inches, feet, yards, miles, etc.) is also used in the United States whereas the SI/metric system (centimetres, metres, kilometres, etc.) is the system in use in most of the world, "football" is jokingly referred to in the title text as the SI name for "soccer". As much of the web panders to a significantly US-based audience{{fact}}, many sites may use only Imperial measurements and omit metric equivalents, which might cause annoyed international users to respond; Randall parodies this by sarcastically and non-seriously apologizing.{{fact}}

Ironically, the UK is the birthplace of association football, and the origin of the term "soccer" — originally to distinguish it from rugby football ("rugger") 'American' football (gridiron, or jocularly "hand-egg"), and 'Aussie Rules' football, before soccer became the most common form of football and is now considered the "default" style of football. The UK is also a partial hold-out for imperial measures. Officially many everyday measurements must now be primarily given in their metric forms, if not more specifically SI, but in the UK and the US road distances remain signed in miles (though horse racing distances remain in furlongs, and their prizes in guineas), with road-speeds in miles per hour; glasses of brewed alcohol and doorstep milk deliveries are in pints (indeed, it is ''illegal'' in the UK to sell draught beer or cider except as a ⅓ pint or multiple of a half-pint); feet (plus inches) and stones (plus pounds) are still commonly used for a person's height and weight. As a further sop to those who still think better in 'old money' measures (an allusion to how the currency itself was non-metric in nature until 1971), a weather presenter may add to their summary (with the windspeeds in mph, except when in Beaufort scale) the equivalent Fahrenheit temperatures involved, in addition to the more official (i.e. 'new money') Celsius variety, and perhaps also give the inches version of any rainfall mentioned.

Incidentally, the presentation of the truncated-icosahedral 'football', pressing one clear polygonal face up along the upper limit of the planetary sphere, has much in common with the (non-truncated) icosahedron that floats within a {{w|Magic 8-Ball}}, ultimately to display just one random triangular face against its upturned viewing window. This may be coincidence, without any obvious attempt to directly reference any of the likely memes relating to this.

2511: Recreate the Conditions

2021-09-05T02:08:03Z

172.68.133.217: /* Explanation */

{{comic
| number = 2511
| date = September 3, 2021
| title = Recreate the Conditions
| image = recreate_the_conditions.png
| titletext = We've almost finished constructing the piña collider.
}}

==Explanation==
{{incomplete|Created by a BIG BANG FLAVORED PIÑA COLLIDER. Do NOT delete this tag too soon.}}

Scientists recreate conditions of things to gain scientific knowledge on a topic to better be able to observe why or how things happen. This could be done by making miniature versions of events and simulating events using safe methods.

In this comic, [[Megan]]'s lab apparently tried to recreate the conditions during the seconds after the {{w|Big Bang}}, and were surprised when it turned out the conditions were extremely hot and unpleasant and thus decided to attempt to recreate the conditions of a {{w|tropical}} {{w|beach}} in 2014 instead (7 years ago from when this comic was released). Here, the joke is that instead of undergoing this simulation for scientific study purposes, it seems that Megan and her crew were simply trying to create a pleasant environment for personal pleasure.

The title text is a reference to [[1949: Fruit Collider]] a pun of {{w|piña colada}} (Spanish for "strained Pineapple") and a particle {{w|collider}}: the Spanish word "colada" is pronounced similarly to the English word "collider". Taken literally, "piña collider" would be a pineapple collider, which may be interpreted as a fruit juicing machine for making piña coladas.

Part of the joke here involves somebody changing their behavior from something productive to something pleasant, similar-sounding, and unproductive. This can mean a lot of things to a lot of different people. One interpretation is that a big bang simulation could involve the formation of the spacetime we live upon, including the structure of time itself. Harming time could produce an impossible timeline, resulting in different behaviors happening for strange reasons. This is similar to developing an AI that learns to manipulate you into no longer working on it, somewhat reminiscent of the title-text of the previous comic.

2511: Recreate the Conditions

172.68.133.217: Big Bang is explodey

==Explanation==
{{incomplete|Created by a BIG BANG FLAVORED PINA COLLADER. Do NOT delete this tag too soon.}}

Scientists recreate conditions of things to gain scientific knowledge on a topic to figure out why or how things happen. This could be done by making miniature versions of events and simulating events using safe methods.

In this comic, [[Megan]]'s lab apparently tried to literally recreate the conditions during the seconds after the Big Bang. This seems to have failed as the conditions involve temperatures over a billion kelvin. Raising the temperature of the laboratory to this value would be lethal to human life.{{citation needed}} Even if it were possible, creating conditions truly identical to seconds after the Big Bang would almost certainly cause a new universe to expand and explode outwards from the location of the lab, proving highly hazardous to the lab, the Earth, and probably much of the immediate interstellar neighborhood.

In the third panel, the lab decided to recreate something more enjoyable, such as the conditions on a tropical beach in 2014 (7 years ago from when this comic was released). This is safer than creating the big bang but doesn't give much useful information.

The title text is a reference to [[1949: Fruit Collider]] a pun of {{w|piña colada}} and a particle {{w|collider}}.
