# Talk:2063: Carnot Cycle

The Carnot cycle is a theoretical construct from thermodynamics describing an ideal way to produce work using a temperature differential. The shape of the diagram matches diagrams of said cycle. The different stages in the Carnot cycle are either isentropic or isothermal. 'Isometric', 'Isotonic', and 'Isopropyl' all play on the 'iso' prefix. 'Isometric' also describes the shape of the diagram. 'Isotonic' seems to have something to do with muscles... which I suppose have some relation to engines as well—they both do work. 172.69.218.52 16:11, 24 October 2018 (UTC)

Did anyone notice that there is a note on the top of XKCD about how to register to vote? Zachweix (talk) 17:18, 24 October 2018 (UTC)

Randall often gives some hints to elections, in this case it's the United States House of Representatives elections, 2018 on November 6, 2018. --Dgbrt (talk) 17:30, 24 October 2018 (UTC)
There are other things being voted on, aside from the House of Representatives. One third of the United States Senate is also up for election (as happens every two years), as well as numerous state offices.173.245.48.171 20:35, 24 October 2018 (UTC)

Please read the Editor FAQ about tables, this here was a good example where tables should not be used (check the history at this comic for the former layout.) Furthermore we should explain the comic but not the real Carnot Cycle, that's done in the Wiki link or at least it should be done in a separate chapter. --Dgbrt (talk) 18:06, 24 October 2018 (UTC)

I'm sure it doesn't need a full explanation, but because the pairings of the stages are part of the joke, I think it's necessary to explain what each stage is. But just enough to explain the contrast. –P1h3r1e3d13 (talk) 18:39, 24 October 2018 (UTC)
I agree. --Dgbrt (talk) 18:46, 24 October 2018 (UTC)
Thermodynamics is the hell! I've always hated it. But I entered the essential original terms with a short explanation. And now I feel we should reverse-translate Randalls words to the real thing, or more precise: a similar sentence using accurate words. --Dgbrt (talk) 20:36, 24 October 2018 (UTC)

Inflation is probably wrong explained

One section before dark energy is mentioned, in Cosmology this energy causes the cosmic inflation. I'm sure Randall talks about this. But maybe we just should mention both. --Dgbrt (talk) 18:12, 24 October 2018 (UTC)

Is there a pun in the title text on token-ring (Tolkien ring) networks? Mlv (talk) 18:39, 24 October 2018 (UTC)

Nice idea, but I don't see that because there is no IBM here. --Dgbrt (talk) 20:40, 24 October 2018 (UTC)

Wagner Ring Cycle probably refers to a part of the Five-Minute Comics: Part 1 in which Cueball and Bach are running away from Wagner, who is on his ring cycle.
