I love this question. The 3rd law of thermodynamics does not allow an electron to be at rest.

Does Quantum Mechanics affect this at all, since an electron's momentum (a measure of speed) and position are decribed by probablity functions? In other words, with probability theory, isn't it more correct to say that it is highly improbable that an electron would have a speed of zero, rather than to say that such a thing is impossible? After all, there is a finite yet very small probablity that an electron in the period at the end of a senetence just traveled to the Andromeda Galaxy and returned immediately thereafter.

Does Quantum Mechanics affect this at all...

My brain hurts!

But seriously I was trying to answer more generically. I think you're right. A bound electron would end up in a finite energy state - it's minimum or zero point energy state. Off the top of my head, I don't remember exactly how to treat an unbound electron, but the uncertainty would put a non-zero minimum limit on its energy.

I'll telepathically summon the master.
