For 10 points, name this thermodynamic quantity that measures the disorder of a system.
In developing information theory, Claude Shannon modified an equation that set this quantity proportional to the sum of the probability that a particle is in a particular microstate times the natural log of that probability. More commonly, that formula states that this quantity equals k times natural log of omega, a formula inscribed on Ludwig (*) Boltzmann's ("BOLTS"-mons) tombstone. The Second Law of Thermodynamics suggests that it never decreases in isolated systems. For 10 points, name this thermodynamic quantity that measures the disorder of a system.
