What's The Definition Of Entropy?
[n] (communication theory) a numerical measure of the uncertainty of an outcome; "the signal contained thousands of bits of information"
[n] (thermodynamics) a measure of the amount of energy in a system that is no longer available for doing work; entropy increases as matter and energy in the universe degrade to an ultimate state of inert uniformity Synonyms | Synonyms for Entropy: information | selective information Related Terms | Find terms related to Entropy: abeyance | aloofness | amorphia | amorphism | amorphousness | anarchy | apathy | bit | blurriness | catalepsy | catatonia | channel | chaos | communication explosion | communication theory | confusion | data retrieval | data storage | deadliness | deathliness | decoding | derangement | diffusion | disarrangement | disarray | disarticulation | discomfiture | discomposure | disconcertedness | discontinuity | discreteness | disharmony | dishevelment | disintegration | disjunction | dislocation | disorder | disorderliness | disorganization | dispersal | dispersion | disproportion | disruption | dissolution | disturbance | dormancy | EDP | electronic data processing | encoding | formlessness | fuzziness | haphazardness | haziness | incoherence | inconsistency | indecisiveness | indefiniteness | indeterminateness | indifference | indiscriminateness | indolence | inertia | inertness | information explosion | information theory | inharmonious harmony | irregularity | languor | latency | lotus-eating | messiness | mistiness | most admired disorder | noise | nonadhesion | noncohesion | nonsymmetry | nonuniformity | obscurity | orderlessness | passiveness | passivity | perturbation | promiscuity | promiscuousness | randomness | redundancy | scattering | separateness | shapelessness | signal | stagnancy | stagnation | stasis | suspense | torpor | turbulence | unadherence | unadhesiveness | unclearness | unsymmetry | untenacity | ununiformity | upset | vagueness | vegetation | vis inertiae See Also | conformational entropy | information measure | physical phenomenon Entropy In Webster's Dictionary \En"tro*py\, n. [Gr. ? a turning in; ? in + ? a turn,
fr. ? to turn.] (Thermodynamics)
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.
The entropy of the universe tends towards a maximum.
