For Boltzmann I was thinking of this passage, which is a translated transcription of a talk called "the second law of thermodynamics", given in 1886. It might not be as explicit as later authors, but it's clear he understood the point.

I think it's a limit (a slightly generalised pullback), the universal thing that completes this diagram
![A commutative diagram showing
* [0,1]^3, meaning the product of the unit interval with itself three times
* its three projections into [0,1]^2
* inclusions of the letters G, E, and B into each of those unit squares
* the universal property of the maximal subset of [0,1]^3 such that its three projections lie inside the letters G, E and B](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:xpl57er4zbahuoaqis6qatin/bafkreigqvhevsxcmgdqgo472unhcmolhqlaaqcsd3yhtif5poqaejigtp4@jpeg)

I wrote an equation that I thought was great, so I drew a star next to it, but then I realised it was wrong, so I drew a sad face on the star, but then I realised it was right after all, and now I've got pages of notes about "the sad star equation".
