(1) irreversible processes are as real as reversible ones. (2) irreversible processes play a fundamental constructive role in the physical world. (3) irreversibility is deeply rooted in dynamics.

Entropy is the price of structure.

The future is uncertain... but this uncertainty is at the very heart of human creativity.

The world is richer than it is possible to express in any single language.

The idea of spontaneous generation of life in its present form is therefore highly improbable even to the scale of the billions of years during which prebotic evolution occurred.

It is a remarkable fact that the second law of thermodynamics has played in the history of science a fundamental role far beyond its original scope. Suffice it to mention Boltzmann's work on kinetic theory, Planck's discovery of quantum theory or Einstein's theory of spontaneous emission, which were all based on the second law of thermodynamics.

The real is only one realization of the possible.
