equipartition

(ˌɛkwɪpɑːˈtɪʃən)
n
(General Physics) the equal division of the energy of a system in thermal equilibrium between different degrees of freedom. This principle was assumed to be exact in classical physics, but quantum theory shows that it is true only in certain special cases

Intuitively, McMillian's Equipartition Theorem indicates that, except for a set of possible sequences of length n which has only a very small chance of occurring (probability less than [Epsilon]), all possible sequences of length n are essentially equally likely to be observed, that is, the probability of each sequence being about exp {-n H}).
