Episode notes

David and I were perfectly aware that we were engaged in a little bit of self mockery when we used that term. We wrote another paper about ever-eddy and quantum mechanics in order to make fun of it, which we call the many minds that kind of quantum mechanics. And there are people who wrote papers taking it seriously because we didn't say at the beginning, this is in order to show what's wrong with many whatever quantum mechanics. But you do take the ridiculous seriously.

The founders of statistical mechanics in the 19th century faced an uphill battle to convince their fellow physicists that the laws of thermodynamics could be derived from the random motions of microscopic atoms. This insight turns out to be even more important than they realized: the emergence of patterns characterizing our macroscopic world relies crucially on the increase of entropy over time. Barry Loewer has (in collaboration with David Albert) been developing a theory of the Mentaculus — the probability map of the world — that connects microscopic physics to time, causation, and other familiar features of our experience.
