摘要:
Information is quantitatively defined in terms of probability, and the statistical interpretation of entropy is given. Entropy change and information are shown to be related on a physical basis, treating a simple volume expansion as an example. Maxwell's demon is discussed as an example of an irreversible process. The argument used by Brillouin in his discussion of the demon is corrected. A generalized second law of thermodynamics is set forth.
