Ectropy

In thermodynamics, ectropy is a measure of the tendency of a dynamical system to do useful work and grow more organized.^[1] Ectropy, in a loose sense, can be thought of as the opposite of entropy. Ectropy is minus entropy. That is, instead of saying "lose entropy" you can say "gain ectropy", instead of saying "gain entropy" you can say "lose ectropy".
