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:
“Powerful, yes, that is the word that I constantly rolled on my tongue, I dreamed of absolute power, the kind that forces others to kneel, that forces the enemy to capitulate, finally converting him, and the more the enemy is blind, cruel, sure of himself, buried in his conviction, the more his admission proclaims the royalty of he who has brought on his defeat.”
—Albert Camus (1913–1960)
