Entropy, английский
- Энтропия
- Entropy is a measure of the disorganization or information within a system. the entropy is lowest when there is a certain outcome or state, and highest when all the possible states are equally likely. for a discrete system with k states, it is defined as where pi is the probability of being in state i. see also: fuzzy entropy, maximum entropy principle.
- ->statistical entropy, a measure of variation, dispersion or diversity; ->thermodynamic entropy, a measure of unusable energy. the similarity between the two types of entropy is merely formal in that both are expressed as the logarithm of a probability. t
- The level of disorder in a system.
- From the second law of thermodynamics, the measure of disorder in a system.
- A measure of the level of disorder or randomness in a closed system. it can be thought of either in the sense of thermodynamic/metabolic processes or the increasing molecular disorder in a structure. it can be thought of as the same process by which erosion occurs when soil is exposed to rain and wind.
