    The difference between the entropy of a system and the maximum possible entropy of the same system.

    • The same magnitude, but with a minus sign, i.e., the measure of macroscopic ordering, the measure of non-uniformity in the distribution of heat, the measure of the differences in temperature—temperature gradients—is called negentropy.
    • Negentropy is the difference between the entropy of a system and the entropy of the same system at equilibrium (i.e., when it has its maximum possible entropy). Since entropy measures the amount of disorder, negentropy measures order.

    The difference between the entropy of a probability distribution and the maximum possible entropy of the same probability distribution.
