Absolute Versus Statistical Reversibility
Thermodynamics defines the statistical behaviour of large numbers of entities, whose exact behavior is given by more specific laws. Since the fundamental theoretical laws of physics are all time-reversible, however experimentally, probability of real reversibility is low, former presuppositions can be fulfilled and/or former state recovered only to higher or lower degree (see: uncertainty principle). The irreversibility of thermodynamics must be statistical in nature; that is, that it must be merely highly unlikely, but not impossible, that a system will lower in entropy.

Famous quotes containing the word absolute:
“José’s my first non-rat romance. Not that he’s my idea of the absolute finito. He’s too prim and cautious to be my absolute ideal, Now, if I could choose from anybody alive, I wouldn’t pick José. Nehru, maybe, or Albert Schweitzer. Or Leonard Bernstein.”
—George Axelrod (b. 1922)
