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)
