A deterministic entropy to monitor the evolution of microscopically simulated far-from equilibrium structures. (pdf)

Chaos, Solitons & Fractals, 19/4, 699-703 (2004).

Abstract:

The cosmos seems live on entropy according to Boltzmann. Prigogine calls "live" structures like stars, flames and organisms "dissipative structures". A new functional of the microstate of realistic computer-implementable far-from-equilibrium systems is explained in its geometric and intuitive content. It can be combined with an exactly invertible algorithm to reveal the essence of a microscopically described system's inexorable approach towards equilibrium. All life-like roundabout ways can for the first time be studied in detail both forwards and backwards in time, so that their secret can be lifted.
