An important extensive property of all systems in thermodynamics, statistical mechanics, and information theory, quantifying their disorder (randomness), i.e., our lack of information about them. It characterizes the degree to which the energy of the system is *not* available to do useful work.

Hydrodynamics, isocurvature and entropy
If I perturb the system, is there any limit in which entropy production of iso-curvature perturbations is negligible? … The reason I ask is that I was reading lecture notes on cosmology and that claimed it was legitimate to treat cosmological iso-curvature as essentially entropy preserving, but I am having trouble imagining …
