Absolute zero is the temperature (-273.15C) at which all motion in matter stops and is thought to be unreachable. But recent experiments using ultracold atoms have measured temperatures that are, in ...

There’s a whole mirror world of negative temperatures reaching from minus infinity to absolute zero – now we’re plumbing those depths for real DEFINING a temperature scale is easy. Fire is hot, ice is ...

IN a recent communication 1 Groves and Lielmezs express the absolute temperature scale in a form symmetrical about the arbitrary zero, with the absolutely highest and lowest temperatures placed at + ∞ ...
