Noise Quotes - page 16
Higher, directed forms of energy (e. g., mechanical, electric, chemical) are dissipated, that is, 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.
Ludwig von Bertalanffy
