"Entropy continually increases. We can, by isolating parts of the world and postulating rather idealized conditions... arrest the increase, but we cannot turn it into a decrease. ...The law that entropy always increases—the second law of thermodynamics—holds... the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is... found to be against the second law... I can give you no hope; there is nothing for it but to collapse in deepest humiliation."
