anentropy

English

Etymology

an- +‎ entropy

Noun

anentropy (countable and uncountable, plural anentropies)

1. (physical chemistry, thermodynamics, countable and uncountable) A measure of the purity or chemical affinity in a thermodynamic system.
   • 2001, Automatic Documentation and Mathematical Linguistics, page 15:

     Treivus has pointed out that the anentropy, apart from a constant factor (the universal gas constant) is equal to the chemical affinity for one componenent in a themodynamic system.

2. (statistics, countable and uncountable) A measure of the simplicity or purity of a distribution.
   • 2004, F. Wall, A. N. Zaitsev, Phoscorites and Carbonatites from Mantle to Mine, →ISBN, page 66:

     The advantages of the RHA method are that it is flexible and can deal with all variants of phoscorites, including diopside and phlogopite-bearing varieties, as well as the continuous series through to carbonatite (Table 2.4) and other related rocks. It gives a measure of complexity of composition and of minor components in the entropy and anentropy values.

   • 2012 March, Томас Георгиевич Петров, S.V. Moshkin, “RHA (Т)-System for Coding of Discrete Distributions and Their Alteration Processes”, in Proceedings of the 3rd International Multi-Conference on Complexity, Informatics and Cybernetics IMCIC-2012:

     Here, R is rank formula of composition – a sequence of components by reduction of their value (contents); Н is Shannon information entropy – complexity measure; А – anentropy – measure of purity; Т – tolerance – measure of ultrapurity.

3. (uncountable) An increase in order.
   • 1997, Robert L. Schwarz, Metaphors and Action Schemes: Some Themes in Intellectual History, →ISBN:

     All these assume a kind of anentropy, a rising of order out of disorder, implicitly embodying a kind of anthropic intent, which Plato articulated as the soul, identified as the primal mover, the initiator of action.

   • 2000, D. B. Clark, Self-Development and Transcendence, →ISBN, page 57:

     It is anentropy in the midst of entropy. Therefore, regarding life as defined the concept of homeostasis is only applicable in a relative sense.

   • 2014, Colin Hannaford, Educating Messiahs, →ISBN, page 40:

     Science has the happy distinction of finding a balance between entropy and anentropy: between the need to conserve order with progress.
