A thought experiment called Maxwell's Demon supposedly (*) decreases this value, even though this value is always increasing in the universe according to the Second Law of Thermodynamics.
Shannon's version of this quantity applies to information systems. Equal to the number of microstates in a system times Boltzmann's constant, this quantity can also be expressed as the amount of energy in a system unavailable to do work. A thought experiment called Maxwell's Demon supposedly (*) decreases this value, even though this value is always increasing in the universe according to the Second Law of Thermodynamics.
