If you want branches, then reality ought to happen more than one way. But it does not, does it? — god must be atheist
And so it goes from one microstate (minimum disorder, simplicity) to N microstates (maximum disorder, complexity) of a macrostate, no?In quantum mechanics, entropy is basically the number of microstates -- exact and degenerate quantum states -- that make up a macroscopic state. — Kenosha Kid
Doesn't it? Why would you think it didn't? — Pfhorrest
You're applying the wrong standard of justification. "This definitely doesn't happen unless you can prove that it definitely does" would require a retreat to abject nihilism because nothing can be conclusively proven. The correct standard is "this might possibly happen unless you can prove that it can't possibly". So I'm asking you to prove that it can't possibly, or else admit that it might. Just saying "prove that it definitely can" doesn't prove that it can't possibly. — Pfhorrest
This is a very good explanation except there is no definition involved. Could you please rephrase this to make it into a proper definition?Thus as you add energy to a bound electron, you increase the number of equivalent states it could end up in, which is how entropy is defined in QM — Kenosha Kid

S = k ln(W)
Entropy S is Boltzmann's constant k times the natural log of the number of microstates W. — Kenosha Kid
Theoretically there is an infinite number of microstates. — god must be atheist
Thank you. What is the unit of entropy in QM? This definition only yields a number. A number alone is not a physics value.Degenerate microstates for a particular macrostate. — Kenosha Kid

Boltzmann's constant has an SI unit of Joules (energy) per degree Kelvin (temperature), so entropy is the same. These are easily Googlable questions btw. — Kenosha Kid
