When We Do (and Do Not) Have a Classical Arrow of Time

Published online by Cambridge University Press:  01 January 2022

Abstract

I point out that some common folk wisdom about time reversal invariance in classical mechanics is strictly incorrect, by showing some explicit examples in which classical time reversal invariance fails, even among conservative systems. I then show that there is nevertheless a broad class of familiar classical systems that are time reversal invariant.
