The meaning of the second law is quite trival. It's the ultimare non-sensical extrolation of infintesmal calculus that physics cranks have ever discovered. Which doesn't mean that it's a law of anything, other than a law of calculus. And it's doesn't mean that the "law" is true or even relevent about anything in the entire univese other than statistical temperature scales, as applied to ground planes, Which is obviously why Maxwell quite immediately violated the moron law, by simply predicting the speed of light for the thermodynamics cranks.
