In the transcript, Cueball is described as standing behind a podium. He may be standing /on/ a podium, but he is standing /behind/ a lectern.&lt;br /&gt;

::No - https://www.differencebetween.com/difference-between-lectern-and-vs-podium/&lt;br /&gt;
::No. Podium (from the Latin root meaning &amp;quot;foot&amp;quot;) is the thing you stand on, a raised platform or dais. Lectern (from Latin &amp;quot;to read&amp;quot;) is the stand that provides a place for notes or other written prompts, from which a speaker may read during a lecture or presentation. It's not uncommon for people to conflate them. [[User:Seezee|Seezee]] ([[User talk:Seezee|talk]]) 18:02, 5 April 2019 (UTC)&lt;br /&gt;
:::If enough people conflate them, it's not a mistake any more, it becomes another definition.

[[User:Seezee|Seezee]] ([[User talk:Seezee|talk]]) 18:23, 5 April 2019 (UTC)&lt;br /&gt;
&amp;quot;Enough people&amp;quot; is fine grammatically because &amp;quot;enough&amp;quot; can refer to either an amount or a number; it the case of &amp;quot;enough people&amp;quot; it's referring to a number of people.

:Thank ''goodness'' someone corrected that. A million people using the wrong word doesn't mean it's the right word (especially when the root words have obviously different meanings); It just means a million people are using unclear\inaccurate language. Common usage ≠ correct usage. It's utility that matters: In this case, if a lectern is also a podium, what is the thing you stand on??? Podium is a common error, but it's still an error. Popularity doesn't equal truth. [[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 20:26, 5 April 2019 (UTC)&lt;br /&gt;
::That is very incorrect. Language is not a natural resource; it can't be measured or described outside of how it is used. If podium commonly used and understood to mean the thing you stand behind, and it's been used that way by many people for a long tome, the thing you stand behind is a podium. You can disagree with that usage all you like, it isn't any less correct. [[User:HisHighestMinion|HisHighestMinion]] ([[User talk:HisHighestMinion|talk]]) 13:26, 6 April 2019 (UTC)&lt;br /&gt;
:I would call that a stool. Also, FWIW, words have different meanings from their roots all the time. Incredible originally meant unreliabe. [[Special:Contributions/162.158.62.67|162.158.62.67]] 14:16, 7 April 2019 (UTC)&lt;br /&gt;

Ah, Pinterest. That website where you have to create an account to view pictures. And then once you do that and get to the post you want, you discover the original “pinner” literally just posted a photo from somewhere with zero indication of where it came from or how to find it so now you’re back to square one but have wasted a bunch of time, been spammed to death by emails and sold your soul to Pinterest.

I don't think we understand this joke at all.  This image was supposed to be released on April 2017 and is now being released on April 2019.  This must be relevant.  Is the black hole only visible once a year due to our orbit?  Sounds relevant if so.  Why couldn't they release it in _2018_ if 2017 didn't work?

{{incomplete|Oops, we forgot to explain the title text.}}&lt;br /&gt;
{{w|Geocaching}} is a sport where you have to find things hidden by other people based on geographical coordinates. Randall has had a similar idea before in [[201: Christmas GPS]].&lt;br /&gt;
&lt;br /&gt;
[http://wiki.xkcd.com/geohashing/ Geohashing] is a sport created by Randall based on reaching a random location determined by an [http://wiki.xkcd.com/geohashing/Algorithm algorithm] that uses a {{w|hash function}} that involves the current date, location and the {{w|Dow Jones Industrial Average|Dow}} opening price. The Dow Jones Industrial Average is a {{w|stock market index}} dealt in New York City.&lt;br /&gt;
&lt;br /&gt;
The algorithm is built in a way that:&lt;br /&gt;
*Makes it impossible to plan a meeting in advance - because of the Dow.&lt;br /&gt;
*Changes every day.&lt;br /&gt;
*Gathers people that are nearby - everyone within the same 1°×1° grid square gets the same position.&lt;br /&gt;
&lt;br /&gt;
The algorithm works as follows:&lt;br /&gt;
# Take the current date in the format yyyy-mm-dd- and append the most recent opening value for the Dow Jones Industrial Average.&lt;br /&gt;
# Pass this string through the MD5 algorithm. &lt;br /&gt;
# Divide the hash value into two 16 character halves, and convert each half to a decimal.&lt;br /&gt;
# Take the integer portions of your current coordinates and append the decimal hash values.&lt;br /&gt;
&lt;br /&gt;
{{w|MD5}} is a cryptographic hashing algorithm, and converts plaintext data into a seemingly random 128-bit (32 character) string. A good hashing algorithm should have three main properties: it is non-reversible and you cannot generate any plaintext data back from the hash, a given sample of data will always produce the same hash value, but even a tiny change to the original plaintext should produce an entirely different hash.&lt;br /&gt;
&lt;br /&gt;
The example co-ordinates are for the Google headquarters in California, as you can see here: [https://maps.google.com/maps?f=q&amp;amp;source=s_q&amp;amp;hl=en&amp;amp;geocode=&amp;amp;q=37.421542+-122.085589&amp;amp;aq=&amp;amp;sll=37.0625,-95.677068&amp;amp;sspn=73.209607,135.263672&amp;amp;vpsrc=0&amp;amp;ie=UTF8&amp;amp;t=m&amp;amp;z=17&amp;amp;iwloc=A 37.421542 -122.085589].&lt;br /&gt;
&lt;br /&gt;
While geohashing was originally intended as a joke, there are people who geohash regularly. Please see the link to the xkcd wiki above.&lt;br /&gt;

		<summary type="html">&lt;p&gt;172.69.46.58: Added Megan's comment&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1452&lt;br /&gt;
| date      = November 26, 2014&lt;br /&gt;
| title     = Jurassic World&lt;br /&gt;
| image     = jurassic_world.png&lt;br /&gt;
| titletext = Hey guys! What's eating you? Ha ha ha it's me! Oh, what fun we have.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This strip refers to ''{{w|Jurassic World}}'', the new ''{{w|Jurassic Park}}'' movie, and the titular theme park. [[White Hat]] explains to [[Megan]] that, in their park, they have genetically engineered a better {{w|Tyrannosaurus}}. Megan doesn't feel that the historic Tyrannosaurus can be improved upon, but White Hat insists they've created an even more terrifying, smarter ''Tyrannosaurus'' for this new park.&lt;br /&gt;
&lt;br /&gt;
White Hat refers to ''Tyrannosaurus'' as &amp;quot;two decades old&amp;quot;, indicating that he has switched topics from the movie's plot line to the animation techniques that created the {{w|Jurassic Park (film)|Tyrannosaurus on-screen}} in 1993 versus today. Clearly, in the computer animation world, we should be able to create something more convincing with modern technology. Megan comments that she is fairly certain it is older than two decades, suggesting that she is referring to the actual Tyrannosaurus that lived millions of years ago.&lt;br /&gt;
&lt;br /&gt;
In the final panel, White Hat introduces the &amp;quot;new&amp;quot; ''Tyrannosaurus'', who is immediately recognizable as the green ''Tyrannosaurus'' from {{w|Ryan North|Ryan North's}} ''{{w|Dinosaur Comics}}''; specifically, from the last panel of said webcomic - which in turn is from [http://www.smithsonianmag.com/science-nature/interview-with-ryan-north-creator-of-dinosaur-comics-15523444/ clip art]. Anyone who has read so much as a handful of ''Dinosaur Comics'' will know that its ''Tyrannosaurus'' character &amp;quot;T-Rex&amp;quot; is about as far from smart and scary as it is possible for a ''Tyrannosaurus'' to be (see [http://www.qwantz.com/index.php?comic=2739 this example] from the day this comic was released).&lt;br /&gt;
&lt;br /&gt;
The title text is an example of what T-Rex (the character) would say to a couple of humans, and it's a poor joke which would only be funny when it's a talking T-Rex saying it. Despite his goofy mannerisms, he is still a carnivore who attacks (or at least accidentally steps on) humans, as can be seen in panel 3 and 4 of the webcomic.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[White Hat holding one hand up in front om him and Megan are walking together.]&lt;br /&gt;
:White Hat: In ''Jurassic World'', we've used genetic engineering to create a ''better'' dinosaur.&lt;br /&gt;
:Megan: Tyrannosaurus is the most charismatic animal that ever lived, and you think you'll ''upstage'' it?&lt;br /&gt;
&lt;br /&gt;
:[White Hat now holds both his hands up in front of him as he and Megan walk on.]&lt;br /&gt;
:White Hat: ''Tyrannosaurus'' was cool, but it's two decades old!&lt;br /&gt;
:Megan: I think it's a ''little'' older than that.&lt;br /&gt;
&lt;br /&gt;
:[In this frame-less panel White Hat points up as they continue to walk.]&lt;br /&gt;
:White Hat: We took ''Tyrannosaurus'' and we ''improved'' it. Made it scarier, deadlier, smarter.&lt;br /&gt;
:White Hat: Look–there it is!&lt;br /&gt;
&lt;br /&gt;
:[White Hat (drawn without his hat) and Megan are dwarfed in the bottom left corner as they stare up at a facsimile of the green T-Rex from ''Dinosaur Comics''. They only reach T-Rex to it's knees.]&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*In the last panel [[Randall]] forgot to draw White Hat's hat so he looks like [[Cueball]], but from the first panel where White Hat walks with Megan and points up at the Dinosaur, it is clear that it is those two characters that are standing beneath it in this last panel.&lt;br /&gt;
**Note that in the two other comics with T-Rex, Randall put in a small Cueball under the foot of T-Rex in the fourth panel of [[145: Parody Week: Dinosaur Comics]], and in the T-Rex [http://xkcd.com/1350/#p:f2b12f1e-bbae-11e3-801c-002590d77bdd story line] from [[1350: Lorenz]], he also forgot to drawn [[Hairy|Hairy's]] hair, thus also there including Cueball though like here by mistake...&lt;br /&gt;
&lt;br /&gt;
The entire ''Dinosaur Comics'' was parodied in [[145: Parody Week: Dinosaur Comics]], where Randall copied the drawings himself, and T-Rex has appeared in one of the story lines in [[1350: Lorenz]] (see this [http://xkcd.com/1350/#p:f2b12f1e-bbae-11e3-801c-002590d77bdd example story line] and also the Dinosaur section under [[1350:_Lorenz#Themes|Lorenz themes]]), where the actual images from the first three panels of Ryan's comic are used, just like here where it is the last panel which is used.&lt;br /&gt;

The Panama Canal is, as the name suggests, a canal through the country of Panama. It is important for bridging the Atlantic and Pacific oceans, and is an important trade route. The canal is in Panama because this is the narrowest piece of land for crossing between the two oceans.&lt;br /&gt;
&lt;br /&gt;
Cueball proposes an alternate route for the Panama Canal that connects the Arctic Ocean to the Great Southern Ocean instead of connecting the Caribbean Sea to the Pacific Ocean.  His suggested route runs somewhat to the east of the continental divide and has a total length of slightly over ten thousand miles, in contrast to the real-life canal which is only fifty miles long.  The extra length and more-rugged terrain make his proposal much more difficult to build and maintain, unlike the real-life Panama Canal.&lt;br /&gt;
&lt;br /&gt;
Moreover, while the real-life canal significantly shortens the travel distance between major cities on the east and west coasts of the Americas, his alternative offers little benefit over traveling north or south in either the Atlantic or Pacific oceans. In fact, with the lack of currents that can aid travel and the slow speed required to traverse canal locks, it would be significantly slower.&lt;br /&gt;
&lt;br /&gt;
The title text referencing the now-existing Panama Canal, and the fact that Randall's canal would need cross it at some point. The title text suggests that crossing two canals would have to be done via aqueduct, instead of the more useful at-grade crossing. The humor here is that this canal would be one of the most ambitious construction projects in history; an aqueduct being added to the costs is an expense on the same scale of needing an extra screw to hold something in on Apollo XI. The route depicted appears to cross the Mackenzie, Missouri, Rio Grande, and Amazon rivers anyway, so only this additional crossing is apparently &amp;quot;unreasonable.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is standing in front of a poster with two maps showing the Americas. He is pointing to the right one with a stick he is holding in his hand. Specifically to the red line going through the Americas from the Arctic sea above Canada near Alaska, down through North America, through the middle of Central America down through the middle of South America to end up in the Antarctic sea below the tip of South America. On the map to the left there is a similar red line indicating the Panama Canal crossing the thinnest part of Central America from the Pacific Oceanto the Atlantic Ocean. Both lines end in small dots on either &amp;quot;side&amp;quot; of the continent. The two maps have labels above them:]&lt;br /&gt;
:Atlantic-Pacific option&lt;br /&gt;
:Arctic-Antarctic option&lt;br /&gt;
&lt;br /&gt;
:[Caption below the panel:]&lt;br /&gt;
:I still don't understand why the Panama Canal planners rejected my proposal.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*The Panama Canal was the main theme in [[1632: Palindrome]] and there is a scene in [[1608: Hoverboard]] where a [http://www.explainxkcd.com/wiki/images/0/0d/1608_1026x1073y_Ruins_with_Cueball_singing_of_Spiders_and_Panama.png song that Cueball sings] references the canal. {{w|Panamax}} is referenced in the title text of [[1865: Wifi vs Cellular]].&lt;br /&gt;
*If Randall had proposed an alternative Panama Canal when the original was being built, he would have been alive in the early 1900s. Assuming he was 18 at the time (a very generously low estimate), Randall would been born all the way back in 1885. Since Randall is not over 139 years old (citation needed), this is evidently impossible.&lt;br /&gt;
*The second comic in a row with a [[:Category:Maps|map based theme]]. Randall likes maps.&lt;br /&gt;
*A canal crossing a canal occurs at several places. One of the more famous ones is the {{w|Magdeburg Water Bridge}} in Germany. It also features some locks nearby, so ships can change from the canal to the Elbe river, and vice versa.&lt;br /&gt;

Second comic in a row about space. The comic seems fairly self-explanatory to me, but the title text might need a bit more work to explain. I can't even figure out exactly what it means. Something about rushing to get the bare minimum done before the deadline? [[Special:Contributions/172.68.141.100|172.68.141.100]] 17:04, 18 March 2019 (UTC)&lt;br /&gt;
Not sure how to tan on mobile (feel free to do so and delete this tidbit if you want to) but: The throwing a frag filled with flags is symbolic of the standard human explorer tactic. Basically, we tend to shoot first whenever we go to a new place and then promptly place a claim, whether the preexisting landscape has been claimed or not. For instance, the Native Americans. Like, all of them. The tile text, on the other hand, represents attempts to find a solution to half a problem or maybe representing the aforementioned claims bit. But I could be reading into this too much [[Special:Contributions/172.69.46.58|172.69.46.58]] 17:22, 18 March 2019 (UTC)&lt;br /&gt;

OMG, the fake explanation is ROTFL funny! Hopefully whomever writes the correct explanation will keep this first bit of verbiage, just for the humor value, but in case that doesn’t happen, for those who don’t want to dig through the edit history, it currently says:&lt;br /&gt;
:: “This comic describes one of the first faked moon missions, Luna II. The Communist sham was designed to make it look like the Moon was reachable by humans, in order to protect the threatened Zionist conspiracy.&lt;br /&gt;
&lt;br /&gt;
::By discussing this as if it was fact, (((Randall))) is subtly reinforcing Jewish neuroprogramming causing people to believe in ridiculous child's fantasies like space unquestioningly.”&lt;br /&gt;

The word league is in a diamond-shaped region, which probably connotes to the baseball diamond.&lt;br /&gt;
&lt;br /&gt;
I think Randall kind of missed an opportunity with the title text: he should have used the new terms as a way to fill the blank areas in the diagram, for instance 'Great Emerald' for the currently empty set Great+Small+Little+Large.[[Special:Contributions/141.101.99.221|141.101.99.221]] 14:31, 11 March 2019 (UTC)&lt;br /&gt;

::Yes, I believe the diagram is correct now, but as per the title text Randall will start using new combinations of terms, probably to get their usage mainstream and move the location of the words in the diagram. I'm saying he should have created terms that would fill some blank areas. For instance, his Large Dipper would make Dipper appear in the Big+Little+Large area where we already have League.[[Special:Contributions/141.101.99.95|141.101.99.95]] 15:16, 11 March 2019 (UTC)&lt;br /&gt;
:::I understood what you said (the first time around) and agree.  Randall's title text is to acknowledge or engage the patterns he's discovered in the comic (as usual), and he could do that more thoroughly by making up words that would make the chart more balanced.

==Explanation==&lt;br /&gt;
&lt;br /&gt;
This comic gives a set of mock equations. To anyone not familiar with the field in question they look pretty similar to what you might find in research papers or on the relevant Wikipedia pages. Most of the jokes are related to the symbols or &amp;quot;look&amp;quot; of most equations in the given field.&lt;br /&gt;
&lt;br /&gt;
The comic makes jokes about the fields of kinematics, number theory, fluid dynamics, quantum mechanics, chemistry, quantum gravity, gauge theory, cosmology, and physics equations. Of course, all of the equations listed are not real equations (&amp;lt;math&amp;gt;\pi-\infty&amp;lt;/math&amp;gt; and H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;EAT are clearly jokes and making a mockery of the given field). As always, Randall is just having a laugh.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;E=K_{0}t+\frac{1}{2}\rho{}vt^2&amp;lt;/math&amp;gt;&lt;br /&gt;
;All kinematics equations&lt;br /&gt;
Most kinematics equations tend to make heavy use of constants, addition, powers, and multiplication. This specific equation resembles the actual kinematics equation d = vt + 1/2at^2, but replaces a (acceleration) with v (velocity) times &amp;lt;math&amp;gt;\rho{}&amp;lt;/math&amp;gt; (density) and replaces velocity with &amp;quot;K&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt;&amp;quot;, which is not a term used in kinematics.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_{n}=\sum_{i=0}^{\infty}\sum_{\pi=0}^{\infty}(n-\pi)(i+e^{\pi-\infty})&amp;lt;/math&amp;gt;&lt;br /&gt;
;All number theory equations&lt;br /&gt;
Randall jokes about how number theory often involves the use of summations. The use of ''&amp;amp;pi;'' as an integer variable in the double summation is a joke, as ''&amp;amp;pi;'' is essentially always used for the well-known constant 3.14159..., not a variable. The use of ''i'' as a summation variable '''is''' common, though it can also be confused with the imaginary unit &amp;amp;radic;-1. The constants ''e'', ''i'', and ''&amp;amp;pi;'', as well as the theoretical upper bound &amp;lt;math&amp;gt;\infty&amp;lt;/math&amp;gt;, often appear in number theory equations.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\frac{\partial}{\partial{t}}\nabla\!\cdot\!\rho=\frac{8}{23}\int\!\!\!\!\int\!\!\!\!\!\!\!\!\!\subset\!\!\supset\rho\,{ds}\,{dt}\cdot{}\rho\frac{\partial}{\partial\nabla}&amp;lt;/math&amp;gt;&lt;br /&gt;
;All fluid dynamics equations&lt;br /&gt;
Fluid dynamics equations often involve copious integrals, especially those over closed contours as done here, which are often the main telling factors of those equations to an outsider. The time derivative and gradient operator &amp;lt;math&amp;gt;\nabla&amp;lt;/math&amp;gt; are common in fluid dynamics, mostly via the Navier-Stokes equation, and the fluid density &amp;lt;math&amp;gt;\rho&amp;lt;/math&amp;gt; is one of the functions of central importance. The fraction 8/23 is a comically weird choice, but various unexpected fractions do pop up in fluid dynamics. The ds and dt go with the double contour integral (s is probably distance, t is time), but the derivative with respect to &amp;lt;math&amp;gt;\nabla&amp;lt;/math&amp;gt; at the end is very much not allowed.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;|\psi_{x,y}\rangle=A(\psi)A(|x\rangle\otimes|y\rangle)&amp;lt;/math&amp;gt;&lt;br /&gt;
;All quantum mechanics equations&lt;br /&gt;
Quantum mechanics often involves some of the foreign-looking symbols listed, including {{w|Bra–ket notation|bra-ket notation}}, the {{w|Tensor product|tensor product}}, and the Greek letter Psi for a quantum state. Specifically, the left side of the equation is a ket state labeled Psi that depends on x and y (probably positions), while the right-hand side may be an operator A that depends on the state Psi (it is very unusual to have such a dependence) acting on what looks like another copy of that operator which depends on the outer product of states labeled by x and y (again strange). A charitable interpretation could be that the second A is the eigenfunction A of the operator A. Normally this is clearly indicated by giving the operator a “hat” (^ symbol) or making the eigenfunction into a ket eigenstate, but since the equation is intentionally nonsense both A’s are left ambiguous. Also note that the bra-ket math is inconsistent here, as the left side is a ket, but the right side is just two A’s, which are either operators or functions but are definitely not kets.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;CH_4+OH+HEAT\rightarrow{}H_2O+CH_{2}+H_2EAT&amp;lt;/math&amp;gt;&lt;br /&gt;
;All chemistry equations&lt;br /&gt;
Chemistry equations use formulas of chemical compounds to describe a chemical reaction. Such equations show the starting chemicals on the left side and the resulting products on the right side, as displayed. Sometimes such an equation might optionally indicate that an {{w|activation energy}} is required, for the reaction to take place in a sensible timeframe, e.g. by heating. A reaction requiring heating is usually indicated by a Greek capital letter Delta (''&amp;amp;Delta;'') or a specified temperature above the reaction arrow, however this comic uses the &amp;quot;+ HEAT&amp;quot; term on the left side instead. The joke is that Randall interprets &amp;quot;HEAT&amp;quot; to be another chemical, which reacts with Hydrogen (H) to H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;EAT, which is nonsensical, as heat is transferred energy here, not added matter. Regardless of this, Randall gets the {{w|stoichiometry}} of this equation correct, with the same number of all types of 'atoms' on each side of the equation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SU(2)U(1)\times{}SU(U(2))&amp;lt;/math&amp;gt;&lt;br /&gt;
;All quantum gravity equations&lt;br /&gt;
Quantum gravity uses mathematical {{w|Group (mathematics)|groups}} denoted by uppercase letters, as shown. {{w|Special unitary group|SU(2)}}, {{w|Unitary group|U(1)}}, and {{w|Unitary group|U(2)}} are all well-studied groups, though 'SU(U(2))' makes no sense.  The lack of relator means this expression isn't an equation.  Here is a possible pun, on &amp;quot;Sue you too... you won&amp;quot;... &amp;quot;Sue you, you too&amp;quot;, though it's unclear how it fits in here.&lt;br /&gt;
&lt;br /&gt;
:S&amp;lt;sub&amp;gt;g&amp;lt;/sub&amp;gt;=(-1)/(2&amp;amp;epsilon;&amp;amp;#x0304;) i&amp;amp;eth;(&amp;amp;#x302; &amp;amp;xi;&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt; &amp;amp;#x2a22; p&amp;lt;sub&amp;gt;&amp;amp;epsilon;&amp;lt;/sub&amp;gt; &amp;amp;rho;&amp;lt;sub&amp;gt;v&amp;lt;/sub&amp;gt;&amp;lt;sup&amp;gt;abc&amp;lt;/sup&amp;gt;&amp;amp;sdot;&amp;amp;eta;&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt;)&amp;amp;#x302; f&amp;amp;#x0335;&amp;lt;sub&amp;gt;a&amp;lt;/sub&amp;gt;&amp;lt;sup&amp;gt;0&amp;lt;/sup&amp;gt; &amp;amp;lambda;(&amp;lt;span style=&amp;quot;display:inline-block; -ms-transform:rotate(180deg); -webkit-transform:rotate(180deg); transform:rotate(180deg);&amp;quot;&amp;gt;&amp;amp;xi;&amp;lt;/span&amp;gt;) &amp;amp;psi;(0&amp;lt;sub&amp;gt;a&amp;lt;/sub&amp;gt;)&lt;br /&gt;
;All gauge theory equations&lt;br /&gt;
Gauge theory is a subset of field theory. Most gauge theory equations appear to have many strange-looking constants and variables with odd labels.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;H(t)+\Omega+G\!\cdot\!\Lambda...\begin{cases}...&amp;gt;0\mathsf{\ (Hubble\ model)}\\&lt;br /&gt;
...=0\mathsf{\ (Flat\ sphere\ model)}\\&lt;br /&gt;
...&amp;lt;0\mathsf{\ (Bright\ dark\ matter\ model)}&lt;br /&gt;
\end{cases}&amp;lt;/math&amp;gt;&lt;br /&gt;
;All cosmology equations&lt;br /&gt;
Cosmology is the science of the development and ultimate fate of the universe. The joke here may be pertaining to the different models accepted in the field of cosmology. H is the {{w|Hubble's law#Time-dependence of Hubble parameter|Hubble parameter}}, &amp;amp;Omega; is the universal {{w|Friedmann equations#Density parameter|density parameter}}, G is the {{w|gravitational constant}}, and &amp;amp;Lambda; is the {{w|cosmological constant}}.&lt;br /&gt;
&lt;br /&gt;
:&amp;amp;#x0124; - u&amp;amp;#x0327;&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt; = 0&lt;br /&gt;
;All truly deep physics equations&lt;br /&gt;
The joke about the &amp;quot;truly deep physics equations&amp;quot; is that most of the universal physics equations are simple, almost exceedingly so. One example is Einstein's ''E = mc²''.&lt;br /&gt;
&lt;br /&gt;
The title text is referencing the fact that the electric and magnetic fields are often explained to physics students using an analogy with fluid dynamics, as well as the fact that they do share some similarities (only in terms of mathematical description as three-dimensional vector fields) with fluids. The permittivity constant (represented with ''&amp;amp;epsilon;''&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt;) and the permeability constant (represented with ''&amp;amp;mu;''&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt;) are coefficients that relate the amount of charge required to cause a specific amount of electric flux in a vacuum and the ability of vacuum to support the formation of magnetic fields, respectively. They appear frequently in Maxwell's equations (the equations that define the electric and magnetic fields in classical mechanics), so Randall is making the joke that any surface integral with them in it automatically is an electromagnetism equation.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by ONE GUY IN MISSOURI. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
In the US, people in various parts of the country refer to carbonated beverages by {{w|Names for soft drinks in the United States|different names}} such as Soda, Pop, Coke, etc. Generally, the West Coast and Northeast say &amp;quot;Soda&amp;quot;, the South says &amp;quot;Coke&amp;quot; and the rest of the country says &amp;quot;Pop&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
There are various maps of the name differences, including: [http://www.popvssoda.com/]&lt;br /&gt;
&lt;br /&gt;
This map leverages xkcd's mockery-maps of regional and state-by-state differences or variations in the use of language and overlays the regional variances in the terms for soda pop (for example: https://laughingsquid.com/soda-pop-or-coke-maps-of-regional-dialect-variation-in-the-united-states/), as was made trending and popular in 2013. Not only are there far more terms than are actually used by Americans, many are terms for other drinks (mead), unrelated liquids (quicksilver), or copyrighted beverage names less popular than Coke/Coca Cola (Code Red) -- and in one case, something that's not even edible ({{w|cryptocurrency|&amp;quot;Crypto&amp;quot;}}).&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+Map terms (from left to right, approximately)&lt;br /&gt;
|-&lt;br /&gt;
|Fanta&lt;br /&gt;
|Name of a carbonated beverage line&lt;br /&gt;
|-&lt;br /&gt;
|Söde&lt;br /&gt;
|Presumably pronounced &amp;quot;soda&amp;quot; but spelled oddly&lt;br /&gt;
|-&lt;br /&gt;
|True Water&lt;br /&gt;
|Possibly a reference to True Blood, a fictional artificial blood substitute for vampires in The Southern Vampire Mysteries book series by Charlaine Harris, and the television series True Blood.&lt;br /&gt;
|-&lt;br /&gt;
|Crypto&lt;br /&gt;
|A term for encryption, popularized by the rise of blockchain-based currencies.  Not drinkable.  Possibly a joke that the residents of Silicon Valley are actually computers who &amp;quot;drink&amp;quot; crypto (i.e. data).&lt;br /&gt;
|-&lt;br /&gt;
|Yum&lt;br /&gt;
|Refers to {{w|Yum! Brands}}, parent company of several fast food restaurants, which was spun off from PepsiCo, maker of a carbonated beverage, in 1997, and has a lifetime contract to serve their beverages.&lt;br /&gt;
|-&lt;br /&gt;
|Sparkle Fluid&lt;br /&gt;
|Roughly analogously to how &amp;quot;sparkling wine&amp;quot; and &amp;quot;sparkling cider&amp;quot; are carbonated varieties of wine and cider, &amp;quot;sparkling fluid&amp;quot; or &amp;quot;sparkle fluid&amp;quot; would presumably be any carbonated fluid&lt;br /&gt;
|-&lt;br /&gt;
|King Cola&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Pepsi&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Crystal Pepsi}}&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Ichor&lt;br /&gt;
|several definitions (blood of a god (or demon, or, in some dialects, any insect) or watery discharge from a wound).  None of them carbonated.  None of them recommended as a drinkable liquid.  (Well, not by someone with your best interests at heart.)&lt;br /&gt;
|-&lt;br /&gt;
|You-Know-What&lt;br /&gt;
|A phrase typically employed when a more specific term is considered unspeakable.&lt;br /&gt;
|-&lt;br /&gt;
|Tab&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Spicewater&lt;br /&gt;
|Potentially a reference to the spice from ''Dune''.&lt;br /&gt;
|-&lt;br /&gt;
|Softie&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Ohio Tea&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Boat Drink&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Melt&lt;br /&gt;
|Usually used to describe a kind of sandwich where cheese is melted in the center, usually on a griddle. Or maybe just a way to say &amp;quot;no, the *melted* ice&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|Fizz Ooze&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Punch&lt;br /&gt;
|A drink typically found in the juice aisle.  Only sometimes carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Fun Wine&lt;br /&gt;
|Implies that normal wine is not &amp;quot;fun&amp;quot;. &lt;br /&gt;
|-&lt;br /&gt;
|Diet&lt;br /&gt;
|Sometimes refers to a carbonated beverage.  A common request in restaurants, as they often only have a single &amp;quot;diet soda&amp;quot; option for customers to pick. Ironically, &amp;quot;diet&amp;quot; sodas have been causally linked to metabolism related weight gain.&lt;br /&gt;
|-&lt;br /&gt;
|Refill&lt;br /&gt;
|The second glass of whatever you drank previously.  Works for any drinkable liquid.&lt;br /&gt;
|-&lt;br /&gt;
|Tickle Juice&lt;br /&gt;
|Name of a Boston-based jazz band. &lt;br /&gt;
|-&lt;br /&gt;
|Bubble Honey&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Sugar Oil&lt;br /&gt;
|The areas of Oklahoma and north Texas that are shaded produce a significant amount of oil.&lt;br /&gt;
|-&lt;br /&gt;
|The Wet Drink&lt;br /&gt;
|Technically true of all drinks, unless one is attempting to drink sand. &lt;br /&gt;
|-&lt;br /&gt;
|Code Red&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Mead&lt;br /&gt;
|An alcoholic drink.  Traditionally not carbonated.  Often associated with Vikings, and these areas did have many Scandinavian immigrants.&lt;br /&gt;
|-&lt;br /&gt;
|Canadian Ale&lt;br /&gt;
|Probably a reference to the Canada Dry brand of Ginger Ale, a non-alcoholic carbonated beverage.&lt;br /&gt;
|-&lt;br /&gt;
|Aether&lt;br /&gt;
|Could refer to a highly flammable industrial solvent, also used as an anesthetic.  Do not drink.  Also, not carbonated. Alternately, could refer to the nonexistent fluid that was believed to carry light waves before electromagnetism was fully understood, or poetically to the sky; in either case it is not a drinkable liquid (or carbonated).&lt;br /&gt;
|-&lt;br /&gt;
|Carbonated Beverage&lt;br /&gt;
|Technically correct, but a bit of an awkward term due to its unnecessary length.&lt;br /&gt;
|-&lt;br /&gt;
|Mouthwater&lt;br /&gt;
|A play on the term &amp;quot;mouth watering&amp;quot; to describe delicious foods and drinks.&lt;br /&gt;
|-&lt;br /&gt;
|Capri&lt;br /&gt;
|Capri Sun is a brand of juice drinks, typically sold in uncarbonated pouches.&lt;br /&gt;
|-&lt;br /&gt;
|Skim Shake&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Kid's Coffee&lt;br /&gt;
|Somewhat accurate.  Coffee is typically drunk by adults for its caffeine.  Carbonated beverages often have caffeine also, and are often consumed by children.&lt;br /&gt;
|-&lt;br /&gt;
|Regular&lt;br /&gt;
|In the past, referred to gasoline with lead, as opposed to &amp;quot;Unleaded&amp;quot;.  Not a drinkable liquid, and also outlawed.&lt;br /&gt;
|-&lt;br /&gt;
|Tang&lt;br /&gt;
|An orange flavored beverage containing less than 2% juice extract, not carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Formula&lt;br /&gt;
|Typically refers to an artificial replacement for mother's milk.  Not carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Medicine&lt;br /&gt;
|Only sometimes a drinkable liquid.  Never or perhaps almost never carbonated.  Alternatively, a common euphemism for alcohol, or some other drink that the person doesn't want to admit to drinking -- or at least doesn't want to share. &lt;br /&gt;
|-&lt;br /&gt;
|Broth&lt;br /&gt;
|Liquid in which bones, meat, fish, or vegetables have simmered.  Often used as a soup base.  Not carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Fool's Champagne&lt;br /&gt;
|Carbonated beverage is to champagne what fool's gold is to gold.&lt;br /&gt;
|-&lt;br /&gt;
|Sugar Milk&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|No word for them&lt;br /&gt;
|This region of the US does not have a word for carbonated beverages (according to Randall).  Apparently they do not drink them at all.&lt;br /&gt;
|-&lt;br /&gt;
|Hydro&lt;br /&gt;
|A word for water.  Carbonated water does exist, but this word means all forms of water.&lt;br /&gt;
|-&lt;br /&gt;
|Harvard Tea&lt;br /&gt;
|The region shades this way includes {{w|Cambridge, Massachusetts}}, which is home to {{w|Harvard University}}.&lt;br /&gt;
|-&lt;br /&gt;
|Bubbler&lt;br /&gt;
|A nod to another popular map of the same type, exploring the regional dialects used to describe drinking fountains.  Rhode Island and the eastern portion of Wisconsin are the only two locations where 'Bubbler' is commonly used to refer to drinking fountains.&lt;br /&gt;
|-&lt;br /&gt;
|Mouthbuzz&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Brad's Elixer&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Hot Water&lt;br /&gt;
|Not carbonated.  Not even in Jacuzzi and hot tubs.&lt;br /&gt;
|-&lt;br /&gt;
|Fluid&lt;br /&gt;
|A word that means nearly any liquid in existence.  Not specific to carbonated beverages.&lt;br /&gt;
|-&lt;br /&gt;
|Coke Zero&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by ONE GUY IN MISSOURI. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
In the US, people in various parts of the country refer to carbonated beverages by {{w|Names for soft drinks in the United States|different names}} such as Soda, Pop, Coke, etc. Generally, the West Coast and Northeast say &amp;quot;Soda&amp;quot;, the South says &amp;quot;Coke&amp;quot; and the rest of the country says &amp;quot;Pop&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
There are various maps of the name differences, including: [http://www.popvssoda.com/]&lt;br /&gt;
&lt;br /&gt;
This map leverages xkcd's mockery-maps of regional and state-by-state differences or variations in the use of language and overlays the regional variances in the terms for soda pop (for example: https://laughingsquid.com/soda-pop-or-coke-maps-of-regional-dialect-variation-in-the-united-states/), as was made trending and popular in 2013. Not only are there far more terms than are actually used by Americans, many are terms for other drinks (mead), unrelated liquids (quicksilver), or copyrighted beverage names less popular than Coke/Coca Cola (Code Red) -- and in one case, something that's not even edible ({{w|cryptocurrency|&amp;quot;Crypto&amp;quot;}}).&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+Map terms (from left to right, approximately)&lt;br /&gt;
|-&lt;br /&gt;
|Fanta&lt;br /&gt;
|Name of a carbonated beverage line&lt;br /&gt;

|Presumably pronounced &amp;quot;soda&amp;quot; but spelled oddly&lt;br /&gt;
|-&lt;br /&gt;
|True Water&lt;br /&gt;
|Possibly a reference to True Blood, a fictional artificial blood substitute for vampires in The Southern Vampire Mysteries book series by Charlaine Harris, and the television series True Blood.&lt;br /&gt;
|-&lt;br /&gt;
|Crypto&lt;br /&gt;
|A term for encryption, popularized by the rise of blockchain-based currencies.  Not drinkable.  Possibly a joke that the residents of Silicon Valley are actually computers who &amp;quot;drink&amp;quot; crypto (i.e. data).&lt;br /&gt;
|-&lt;br /&gt;
|Yum&lt;br /&gt;
|Refers to {{w|Yum! Brands}}, parent company of several fast food restaurants, which was spun off from PepsiCo, maker of a carbonated beverage, in 1997, and has a lifetime contract to serve their beverages.&lt;br /&gt;
|-&lt;br /&gt;
|Sparkle Fluid&lt;br /&gt;
|Roughly analogously to how &amp;quot;sparkling wine&amp;quot; and &amp;quot;sparkling cider&amp;quot; are carbonated varieties of wine and cider, &amp;quot;sparkling fluid&amp;quot; or &amp;quot;sparkle fluid&amp;quot; would presumably be any carbonated fluid&lt;br /&gt;
|-&lt;br /&gt;
|King Cola&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;

|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|{{w|Crystal Pepsi}}&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Ichor&lt;br /&gt;
|several definitions (blood of a god (or demon, or, in some dialects, any insect) or watery discharge from a wound).  None of them carbonated.  None of them recommended as a drinkable liquid.  (Well, not by someone with your best interests at heart.)&lt;br /&gt;
|-&lt;br /&gt;
|You-Know-What&lt;br /&gt;
|A phrase typically employed when a more specific term is considered unspeakable.&lt;br /&gt;
|-&lt;br /&gt;
|Tab&lt;br /&gt;
|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;

|&lt;br /&gt;
|-&lt;br /&gt;
|Melt&lt;br /&gt;
|Usually used to describe a kind of sandwich where cheese is melted in the center, usually on a griddle. Or maybe just a way to say &amp;quot;no, the *melted* ice&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|Fizz Ooze&lt;br /&gt;
|&lt;br /&gt;

|Implies that normal wine is not &amp;quot;fun&amp;quot;. &lt;br /&gt;
|-&lt;br /&gt;
|Diet&lt;br /&gt;
|Sometimes refers to a carbonated beverage.  A common request in restaurants, as they often only have a single &amp;quot;diet soda&amp;quot; option for customers to pick. Ironically, &amp;quot;diet&amp;quot; sodas have been causally linked to metabolism related weight gain.&lt;br /&gt;
|-&lt;br /&gt;
|Refill&lt;br /&gt;
|The second glass of whatever you drank previously.  Works for any drinkable liquid.&lt;br /&gt;

|Name of a carbonated beverage&lt;br /&gt;
|-&lt;br /&gt;
|Mead&lt;br /&gt;
|An alcoholic drink.  Traditionally not carbonated.  Often associated with Vikings, and these areas did have many Scandinavian immigrants.&lt;br /&gt;
|-&lt;br /&gt;
|Canadian Ale&lt;br /&gt;
|Probably a reference to the Canada Dry brand of Ginger Ale, a non-alcoholic carbonated beverage.&lt;br /&gt;
|-&lt;br /&gt;
|Aether&lt;br /&gt;
|Could refer to a highly flammable industrial solvent, also used as an anesthetic.  Do not drink.  Also, not carbonated. Alternately, could refer to the nonexistent fluid that was believed to carry light waves before electromagnetism was fully understood, or poetically to the sky; in either case it is not a drinkable liquid (or carbonated).&lt;br /&gt;
|-&lt;br /&gt;
|Carbonated Beverage&lt;br /&gt;
|Technically correct, but a bit of an awkward term due to its unnecessary length.&lt;br /&gt;
|-&lt;br /&gt;
|Mouthwater&lt;br /&gt;

|Skim Shake&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Kid's Coffee&lt;br /&gt;

|-&lt;br /&gt;
|Regular&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;

|Formula&lt;br /&gt;
|Typically refers to an artificial replacement for mother's milk.  Not carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Medicine&lt;br /&gt;
|Only sometimes a drinkable liquid.  Never or perhaps almost never carbonated.  Alternatively, a common euphemism for alcohol, or some other drink that the person doesn't want to admit to drinking -- or at least doesn't want to share. &lt;br /&gt;
|-&lt;br /&gt;
|Broth&lt;br /&gt;
|Liquid in which bones, meat, fish, or vegetables have simmered.  Often used as a soup base.  Not carbonated.&lt;br /&gt;
|-&lt;br /&gt;
|Fool's Champagne&lt;br /&gt;
|Carbonated beverage is to champagne what fool's gold is to gold.&lt;br /&gt;
|-&lt;br /&gt;
|Sugar Milk&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|No word for them&lt;br /&gt;
|This region of the US does not have a word for carbonated beverages (according to Randall).  Apparently they do not drink them at all.&lt;br /&gt;
|-&lt;br /&gt;

|A word for water.  Carbonated water does exist, but this word means all forms of water.&lt;br /&gt;

|The region shades this way includes {{w|Cambridge, Massachusetts}}, which is home to {{w|Harvard University}}.&lt;br /&gt;
|-&lt;br /&gt;
|Bubbler&lt;br /&gt;
|A nod to another popular map of the same type, exploring the regional dialects used to describe drinking fountains.  Rhode Island and the eastern portion of Wisconsin are the only two locations where 'Bubbler' is commonly used to refer to drinking fountains.&lt;br /&gt;
|-&lt;br /&gt;
|Mouthbuzz&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;
|Brad's Elixer&lt;br /&gt;
|&lt;br /&gt;
|-&lt;br /&gt;

|Not carbonated.  Not even in Jacuzzi and hot tubs.&lt;br /&gt;

|-&lt;br /&gt;
|Glug&lt;br /&gt;

|-&lt;br /&gt;
|Water Plus&lt;br /&gt;
|Technically the name of {{w|Water Plus|a British water retail services provider}}, this likely refers to the prevalence of &amp;quot;plus&amp;quot; as a preposition in branding nomenclature (e.g.: {{w|Google+}}, {{w|iPhone 8 Plus}}, {{w|7 Up Plus}}, etc.).&lt;br /&gt;
