Teachable Moment: First, let's admit...it's a cool name... so cool, that rock bands chose it to have geek "cred."
But it's also a fascinating thought experiment that challenges a "law" of thermodynamics.
In 1867, James Clerk Maxwell pictured two chambers, A and B, each filled with gas at the same temperature and with a door between them. Theorists later had a demon open the door (without doing any work) to let the fastest-moving molecules pass from A into B, and the slowest from B to A. Over time, the speed of the atoms (and therefore the temperature) increases in B — a violation of the second law of thermodynamics.
