comment Why does a ball bounce lower?
@Cruncher: I don't think the OP is asking whether it's true, I think the OP is asking why it's true.

comment Why is it said that without quantum mechanics we would not have modern computers?
"chip designs have reached the point of even needing to foresee the Casimir effect" Do you happen to have a link that explains this need?

comment If temperature is average KE per particle, and heat is total KE of all the particles, how can molar heat capacity vary?
I'm slightly confused about something else entirely. Average kinetic energy per mode would be in units of Joules/mode or whatever. Temperature is Kelvin, so how can you even claim they're the same?

comment Is time continuous?
Not 100% related, but you may be interested in Aharonov's time-symmetric formulation of quantum mechanics: en.wikipedia.org/wiki/Two-state_vector_formalism

comment Rotation, cats landing on their feet, and conservation of angular momentum
Ooh... wow, that just blew my mind. So angular velocity isn't defined (or at least not the way I expect) for non-rigid bodies? +1 that explains it, thanks.
