The coins start out as a jumbled mess, but all jump and eventually come to rest with the same side up – an unreal, slightly creepy sequence. Imagine placing 20 coins, heads up, on a tray, filming it as you give it a shake and then playing the film backwards. Its importance is best expressed by sketching out a situation which violates it. The second law of thermodynamics is perhaps the most profound of the three laws of thermodynamics. “If your theory is found to be against the second law of thermodynamics I can give you no hope there is nothing for it but to collapse in deepest humiliation,” he wrote. The British astrophysicist Arthur Eddington have a stern warning to would-be theoretical physicists in 1915. The second law of thermodynamics means hot things always cool unless you do something to stop them. It expresses a fundamental and simple truth about the universe: that disorder, characterised as a quantity known as entropy, always increases.
