= Maxwell's demon
{wiki=Maxwell's_demon}

Maxwell's demon is a thought experiment proposed by the physicist James Clerk Maxwell in 1867. It illustrates a concept in thermodynamics, specifically relating to the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time. In the thought experiment, imagine a container divided into two parts by a wall with a small door that can be opened and closed. The container is filled with gas molecules at an equal temperature.
