The joke is that Cueball, the actual physicist, is not focused at all on the beauty on display, but is instead frustrated with the math in his formulation and just wishes to avoid work in solving his equations. Cueball is annoyed this his equation has two unknowns, which greatly complicates the math he must do. Typically in physics, it is much much easier to solve problems for a single unknown variable, with the work becoming exponentially harder with each new added unknown. A common tactic used to approach such problems is to find a way to separate the two variables, Cueball is shown to be struggling to find such a shortcut.
The title text continues Cueball's thought process, with the possibility of using an equation solver to solve the equations. An equation solver or computer algebra system is a computer program which can be used to solve equations or systems of equations, and is typically not an especially beautiful way to address mathematical problems. Cueball would need to make sure that the equations are entered correctly, with parentheses in the correct places, when inputting them into the solver; again this is an issue far removed from the beauty of mathematics and physics.
Transcript
- [Cueball stands in front of a blackboard full of formulas and diagrams. White Hat is watching him from a couple meters away.]
- White Hat (thinking): Amazing watching a physicist at work, exploring universes in a symphony of numbers.
- White Hat (thinking): If only I had studied math, I could appreciate the beauty on display here.
- Cueball (thinking): Oh no. This has two unknowns. That's gonna be really hard.
- Cueball (thinking): Ughhhhhhh.
- Cueball (thinking): Think. There's gotta be a way to avoid doing all that work...
Discussion
This makes me think of my profession (software engineer) - Normie: "Oh wow, that looks complicated!" Me: wires two pre-existing libraries together and calls it a day Baldrickk (talk) 09:39, 26 September 2019 (UTC)
- Image of Blackboard
I was looking at the blackboard and was wondering if there were any Easter eggs on it. Here is the result of my badly cropped photoshopping skills. [1] idk if it would help to sharpen the image. --DarkAndromeda31 (talk) 01:25, 26 September 2019 (UTC)
- The only thing that really jumps out at me are the wedges, as portions of pie charts where radius also controls area, evoking the climate stabilization wedge game from Princeton where the total area of the disk needing to be mitigated is something like 38 gigatons of atmospheric carbon, and the various mitigation solutions have angles representing potential and radius indicating uptake, the proportion of which represents gigatons mitigated as the wedge area. We can offer that game as an example of a bivariate optimization problem which might not have to be manually solved by anyone, if we assume that the local market for surplus potable water, carbon-neutral liquid transportation fuel, and carbon-negative composite lumber for centuries-to-millenia scale sequestration along with wood timber displacement for reforestation represents locally satisfiable economic demand for N shipping containers of Project Foghorn plants and M shipping containers of power-to-gas upgrades for natural gas power plants. That's an example of how a locally market-driven system can solve a bivariate optimization without anyone doing the actual math work in a spreadsheet or otherwise. The economic solution is not necessarily optimal, because even as powerful as the free market can be, it isn't necessarily going to find the bivariate optimums for every point on the planet (although it will likely converge asymptotically in some sense) and defectors such as fossil fuel producers are interested in delaying the optimum solution.
- Is that nontangential enough? 172.68.143.18 20:49, 26 September 2019 (UTC)
- Yes that was far out :-) I'm sure there is nothing interesting hidden in the image. --Kynde (talk) 08:36, 27 September 2019 (UTC)
- Compare the graph at [2] with that at [3]. When will the latter overtake the former? 172.68.142.221 19:19, 27 September 2019 (UTC)
- Soon one may hope, but that has nothing to do with the drawings on the blackboard...? --Kynde (talk) 21:07, 27 September 2019 (UTC)
- "Soon" lacks mathematical precision. How do you feel about distributed constraint optimization? 172.68.142.83 22:56, 27 September 2019 (UTC)
- P.S. I would also point out that this comic appeared during the Global Climate Strike so I stand by my interpretation of the wedges. 162.158.255.136 19:11, 3 October 2019 (UTC)

Does Wolfram Alpha constitute such a problem solver? Cause both Randall and this site has used it on several occasions. But I have not ever really used such things, and do not know if Wolfram can be used as Cueball thinks about in the comic. But if it could, it could be worth mentioning as a method sometimes used by Randall. --Kynde (talk) 08:43, 27 September 2019 (UTC)
- [4] is the first bivariate system of equations example. 172.69.22.134 17:51, 27 September 2019 (UTC)
- Is that then a yes to my question? ;-) --Kynde (talk) 21:07, 27 September 2019 (UTC)
- Do you think it's more worthwhile to include a general discussion of avoiding the work of solving for two unknowns than the climate wedges? Why do you suggest that the wedges aren't the only distinctive elements on the blackboard? 172.68.142.83 22:58, 27 September 2019 (UTC)

I only just now noticed that Randall always puts the crossbars on the I in the word "I" and not otherwise. Looking back, he has nearly always done this, even since the first few comics. That's quite a principled yet subtle stance on letterforms. (There are some exceptions, however, such as comic #87, and a period that goes at least from comic #128 to comic #180. I wonder if it would be too typography-nerdy to put them all in a category.) 198.41.231.85 14:47, 27 September 2019 (UTC)
- Those "crossbars" would be serifs, whereas he normally uses a sans serif font. A sans serif would be quicker/easier to write by hand, but he probably realized early on (perhaps subconsciously) that an I by itself without serifs looks too much like a random line or a numeral 1 so he treats the solo I like a special letter, with serifs. -boB (talk) 15:16, 27 September 2019 (UTC)
Thank you, person who sees beauty in grammar (Jkrstrt). I thought something looked off when I said "often site the beauty they see" but I didn't catch it until you sighted the error and made it cite instead. -boB (talk) 15:10, 27 September 2019 (UTC)
We need something about the 2014 popularity spike of the phrase "They did the math" with a link to e.g. r/theydidthemath. And ask the Hashtag Research Studies group to figure out the cause of that spike. 172.68.189.19 15:29, 29 September 2019 (UTC)
- This has got to be somehow related to xkcd. But how? 172.68.189.19 20:42, 29 September 2019 (UTC)
In other olds, Google Books says it started in 1988 but won't show me the 1988 book in question. I'm going to work on the drone fishing now. 162.158.255.136 05:31, 30 September 2019 (UTC)
Deletions
I feel that these deletions were done without sufficient discussion of the rationales for the material given above, leaving the explanation shorter than that of almost all if not all other comics. Whatever you think of the climate change distributed optimization example, there were no objections to the well-documented "they did the math" popularity surge or to the academic references deleted. 172.69.22.68 01:16, 22 November 2019 (UTC)
- How was that even related to the content of the comic? --Lupo (talk) 07:14, 22 November 2019 (UTC)
- Which? The two wedges involving an optimization problem in two variables on Climate Strike Week (a strike being an intentional avoidance of work), or the phrase "They did the math" in relation to "Math work"?
- I intend to replace the deleted material. 172.69.22.68 05:26, 3 December 2019 (UTC)
- Why? please explain how it is relevant/related to the comic or helps in understanding it. The comic is about math being complicated and incomprehensible from outside, while from the inside it is just as complicated when you understand it. The comic does not contain the words "the math" nor does the pie chart or the wedge give any indication of being about anything specific. It is just as likely something about Pizza. --Lupo (talk) 07:24, 3 December 2019 (UTC)
- I have, in detail, above. I have asked famed Bloomberg columnist and fellow economics science communication enthusiast Noah Smith to mediate this dispute. Will you accept him as mediator? 172.68.143.24 12:06, 8 December 2019 (UTC)
- First a personal note: As it seems like we are discussing here, I'd appreciate if you'd create an account here, so that I can link your comments to a single commenter, instead of a changing cloudfare IP adresses. To the topic: I do not deny that a wedge can represent an optimization problem. It can also represent other things. As far as visible from the comic, Cueball could be calculating how much Pizza he has left. Even if it is about an optimization problem, there is no indication in the comic to link this to human-made climate change, apart from the apperance of the comic in climate strike week. If it was a reference to that point, it'd be very (!) subtle. How do you think some spark in the search for some term in 2014, which has a one-word-overlap (and math is the topic of the comic...) with the comic is relevant again? I, again, do not doubt the correctnes of the statements, but only their relevance/connection with this comic. Last but not least: Any registered (and therefore "unique", even though it's easy to register multiple accounts...) commenter may join this discussion, to reach consensus (by the way, I was not even the one deleting it actually). I have never heard of that famed person, nor do I care about his column in some magazine and his enthusiasm about communication. (If he should ever read this, I'd like to repeat myself: I have never heard of him, so it is not meant to disrispect him. He might be a nice guy and very qualified in whatever he writes his column about. He might also be famous to people he is relevant for.) --Lupo (talk) 07:29, 9 December 2019 (UTC)
