different between synergy vs exergy

English

Etymology

From Ancient Greek ???????? (sunergía, “cooperation”), from ??? (sún, “with, together”) + ????? (érgon, “work”).

Pronunciation

• (UK) IPA^(key): /?s?n?d?i/
• (US) enPR: s?n??r-j?, IPA^(key): /?s?n?d?i/

Noun

synergy (countable and uncountable, plural synergies)

1. (systems theory) A synonym of binding energy.
   • 1986, John Andrew Dillon (Society for General Systems Research). Proceedings of the International Conference on Mental Images, Values, & Reality. Vol. 1, Intersystems Publications, p. D-7

     Depending on the initial condition of the system (initial alphabet and number of elements) the co-evolution of nested local and global hierarchies continues until the system reaches a maximum value of complexity. At least for nuclear systems a quantitative variable called "complexity" can be defined, which increases in an irreversible manner during stellar evolution (Winiwarter, 1983). This variable C is composed of an informational measure I describing the variety of the computed formulas and an energetic measure R describing the relative binding energy or "synergy" permitting the coherence of the system.

     In short, synergy is the consequence of the energy expended in creating order. It is locked up in the viable system created, be it an organism or a social system. It is at the level of the system. It is not discernible at the level of the system. It is not discernible at the level of the system's components. Whenever the system is dismembered to examine its components, this binding energy dissipates. An ordered library offers systemic possibilities, such as rapid search, selection, and aggregation, that cannot be explained by looking at the books themselves. These possibilities only exist because of the investment made in defining and creating interrelations between the books, their physical arrangement and the catalogues.

2. (physiology) The cooperation of two or more nerves, muscles, organs, etc.

   the digestive synergy

3. (pharmacology) The combined action of two or more drugs where the effects are stronger than their mere sum.
4. (figuratively) Benefits resulting from combining different groups, people, objects or processes.

Synonyms

Etymology

The term "exergy" was coined in 1956 by Zoran Rant (1904–1972) from Greek ex- ("out of", "away from") + ergon ("work").

Noun

exergy (countable and uncountable, plural exergies)

1. (physics) Concentrated or organized energy, which can be exported and do work in the process.
   • 2002, J. Honerkamp, Statistical Physics, p. 298

     The maximum fraction of an energy form which (in a reversible process) can be transformed into work is called exergy. The remaining part is called anergy, and this corresponds to the waste heat.

Synonyms

• free energy

Antonyms

• anergy
• bound energy
