Physics in a nutshell: two branches of mechanics arguing over the same damn letter while looking at the exact same system. In classical mechanics, nature's lazy and takes the path of least action (S is minimal). In statistical mechanics, entropy (also S) must be maximal because chaos reigns supreme. Same universe, completely opposite principles. The universe is basically that friend who can't decide what they want for dinner but somehow makes both options work. Next time someone asks why physicists drink, show them this.
