“In physics, the idea of progress opposes that of entropy, although there is no absolute contradiction between the two. In the forms of physics directly dependent on the work of Newton, the information which contributes to progress and is directed against the increase of entropy may be carried by extremely small quantities of energy, or perhaps even by no energy at all. This view has been altered in the present century by the innovation in physics known as quantum theory.
Quantum theory has led, for our purposes, to a new association of energy and information.”
