The nature and basis of irreversibility has been intensively investigated over the last 100 years by physicists, mathematicians, and philosophers. But if progress is measured by convergence of opinion among the “experts” then it is hard to detect; in fact the field is a virtual Tower of Babel. J.L. Lebowitz, one of the leading mathematical physicists in the field put it this way:
I do not know if anyone is making bets on the eventual resolution of the apparent paradoxes relating to the coexistence, in the description of the same phenomena, of both determinism and randomness, reversibility and time asymmetry, and so on. If there are people betting, however, I would be very happy to be the banker and keep the money until everyone has agreed on the answer. (Lebowitz 1983, p. 4)
I am grateful to A. Janis and L. Sklar for helpful discussions on these matters.
