"For well over a hundred years, a basic antithesis was noticed between inanimate and animate nature. The direction of physical events is prescribed by the second principle of thermodynamics... the general trend of physical happenings is toward most probable states, that is, maximum entropy and progressive destruction of differentiation and order. ...The system will tend toward thermal equilibrium ...a state of most probable distribution of molecules ...disappearance of the temperature gradient and uniform distribution ...maximum entropy. "Higher," directed forms of energy (e.g., mechanical, electric, chemical) are dissipated... progressively converted into the lowest form of energy, i.e., undirected heat movement of molecules; chemical systems tend toward equilibria with maximum entropy; machines wear out owing to friction; in communication channels, information can only be lost by conversion of messages into noise but not vice versa, and so forth."
