Who needs LN when you have this?

1.9K baby!

Slightly more expensive than LN however.

Guess what LHe is cooled by? That's right, LN2!

All (current generation) supercon magnets in NMRs are cooled with LN2 / LHe.

I understood @ 1/2 of that.

Who thinks of this stuff?

I got to hear a presentation done by a Nobel Lauriette about sub-space temperatures. But, I thought there were down to the terms of micro-Kelvin. I'm looking it up right now, but it was impressive stuff. Atoms go crazy at those low of temperatures. In fact, I was able to see THROUGH a solid, because the particles were so cold. Amazing stuff but WAY over my head.

Very small K has been achieved on a very very microscopic scale. (Counting the number of atoms on one or two hands kind of thing.) This is done on a macroscopic scale.

That's one hell of a profession! :O

Yeah.

This is the guy: Wolfgang Ketterle

He and his team have brought atoms and some small molecules to micro-Kelvin, thousands of times colder than space. Pretty cool stuff, pardon the pun.
