## Main Question or Discussion Point

Hello;

"[itex]S\propto\ln\Omega[/itex], where [itex]\Omega[/itex] is the number of microstates" is what a user told me was the fundamental definition of entropy. What is S? Is it the number of macrostates? And where does the ln come from? Can I see an example of where this formula would be used in practice?

Thanks.
