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:
“Only the more uncompromising of the mystics still seek for knowledge in a silent land of absolute intuition, where the intellect finally lays down its conceptual tools, and rests from its pragmatic labors, while its works do not follow it, but are simply forgotten, and are as if they never had been.”
—Josiah Royce (1855–1916)
