Why doesn't the random quantum movement of these particles cause a system near absolute zero to heat up? If these random quantum flucuations cause the electron to bump into another particle, imparting it with momentum, does that momentum not "count" as heat? Weird.

I think you're assuming absolute zero is possible. That could be one of the reasons that reaching absolute zero is, in fact, not possible.

These videos are awesome.

These videos are fantastic...

The implications of what he mentions about microwave background detection at 4:08..

gave my brain a tingle. = ]

"Uh... *looks around* Where've my atoms gone?" - a great way to start a video.

Man, I love the Sift!

Surprised nobody objected to the word "orbit" in the first question. Yes, for historical reasons physicists talk about electron orbitals, but it's not like the electron's spinning around the nucleus like a planet orbits the sun....

this idea experiment is very interesting stuff and related to this zero temperature electron problem.

Me too.

I wanted to say "uncertainty principle, we can never know where your atoms are" to him at the start.

I think i might have got a physics laugh.

The Irish guy is hot. That is all. *upvote*
