Why Planck's constant is what it is and why it's not constant

[Farsight]

Sorry if this is perhaps a little off topic, but somebody was talking about Planck's Constant. I know why Planck's Constant is what it is. Yes, it's a constant of action, but I know why, and why it's really something else.

 

 

Oh, and guess what, it isn't actually constant. Think Pound-Rebka.

Farsight I hope you will explain. This is an intriguing introduction and naturally raises one's curiosity.

Come on Farsight! You're on to something. Let's hear it.

Are you going to go into quantum mechanics, or not?

OK, I thought about this

http://en.wikipedia.org/wiki/Pound-Rebka_experiment

and I still think Planck's work stands.

Please explain why you think the constant isn't constant.
