Negative temperature misleading

The concept is misleading, IMO. What they did discover is much more remarkable, in fact.

They created an energy state which is opposite to a standard energy state. I suspect this can be done at much higher temperatures too.

They didn’t really get close to absolute zero in that, a Bose-Einstein condensate never manifested, something Schrodinger would insist upon. ;)

They simply got them as close to being still as was practical to watch them moderately well.

The implications of such a field are astounding. It’s sort of an "entropy sink".

Just open the box and see
