The [[second law of thermodynamics]] predicts that such entropy should increase until equilibrium.  But under the theory of statistical mechanics there would always be a nonzero probability that the entropy of an isolated system will spontaneously decrease.  The fluctuation theorem precisely quantifies such probability under the theory of statistical mechanics.
