different between extropy vs ectropy

English

Etymology

First coined to serve as an antonym of entropy, substituting its en- element (representing the prepositional prefix ?? (en), en, “in” in its Ancient Greek etymon ???????? (entropía), entropia, “a turning towards”) with ex- (representing the Ancient Greek ?? (ex), ex, “out of”, “from”); because ?? (ex) takes the form ?? (ek) when prefixed to an element beginning with ? (t), the analogical spelling is ectropy (or, alternatively, ektropy), as if after the Ancient Greek *???????? (ektropía, “a turning out of”).

Etymology

“This term was suggested by W. V. Quine in discussions following this symposium: Entropy, he pointed out, is Greek for turning in; the opposite term should therefore be the Greek for turning out, namely ectropy. Since the coaction cardioid literally turns in and out of the circle of reference, his short, elegant term is used throughout.”

ectropy (countable and uncountable, plural ectropies)

1. (thermodynamics) The overall increase in the organization of a system
