„At its core the Second Law is essentially the statement that “things tend to get more random”.“
This is a common misunderstanding and I’m surprised Wolfram doesn’t seem to get that. A counter example is this: A self-gravitating gas cloud will collapse to a more compact state (a star or in the most extreme case a black hole ). This final state will not look like more random as it is commonly understood.
The second law of physics is essentially the statement that we loose information with time about the initial state.
- ogogmad 4y agoThis is the usual kind of useless pedantry on this site. It's not a misunderstanding. The entropy of a discrete probability distribution is indeed a measure of how random samples from it are. The misunderstanding is by you. See Gibbs and Shannon entropy before commenting on this again.
