n. For a closed thermodynamic system, a quantitative measure of the amount of thermal energy not available to do work.

n. A measure of the disorder or randomness in a closed system.

n. A measure of the loss of information in a transmitted message.

n. The tendency for all matter and energy in the universe to evolve toward a state of inert uniformity.

n. Inevitable and steady deterioration of a system or society.

n. A measure of the amount of information and noise present in a signal. Originally a tongue in cheek coinage, has fallen into disuse to avoid confusion with thermodynamic entropy.

n. The tendency of a system that is left to itself to descend into chaos.

n. A certain property of a body, expressed as a measurable quantity, such that when there is no communication of heat the quantity remains constant, but when heat enters or leaves the body the quantity increases or diminishes. If a small amount, h, of heat enters the body when its temperature is t in the thermodynamic scale the entropy of the body is increased by h ÷ t. The entropy is regarded as measured from some standard temperature and pressure. Sometimes called the thermodynamic function.

n. In physics: As used by Clausius, the inventor of the word, and others, that part of the energy of a system which cannot be converted into mechanical work without communication of heat to some other body, or change of volume.

n. As used by Tait and others, the available energy; that part of the energy which is not included under the entropy in sense .

n. (communication theory) a numerical measure of the uncertainty of an outcome

n. (thermodynamics) a thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work

"A typical rebuttal is to suggest that information entropy and thermodynamic entropy are unconnected, citing the apocryphal story that Shannon picked the term entropy because “nobody understands what it means”."
