Unrelated to the word "daemon", but related to the article, I was a bit surprised by this assertion: > Eventually, though, the theory of quantum mechanics showed why it wouldn't work. I was familiar with the information theory arguments (the same presented in Wikipedia[1]). Is that why they mean here by "quantum mechanics" or is there another counterargument to Maxwell's daemon? 1: https://en.m.wikipedia.org/wiki/Max…
I'm guessing that the daemon's ability to allow only fast molecules through the gate depends on knowing their position and velocity simultaneously?
