This press release is available in German. What is normal to most people in winter has so far been impossible in physics: a minus temperature. On the Celsius scale minus temperatures are only ...

(Phys.org)—A team of physicists in Germany have succeeded in forcing a gas to become colder than absolute zero. Using lasers and a magnetic field to manipulate an ultra-cold gas, the researchers, as ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

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 ...

IN NATURE of July 19 a review entitled “Discursive Meteorology”, meaning as I think ‘discursive physics’, asks a question to which I ought if possible to find an answer. The reviewer writes: “Some of ...

45In meteorology, three different temperature scales are used: Fahrenheit, Celsius, and Kelvin. German-born scientist Gabriel Daniel Fahrenheit developed the Fahrenheit Scale. He introduced his scale ...

Nothing is colder than absolute zero, so it seems nonsensical to talk about negative temperature – but now there is a substance that must have just that. The revelation could shake up our ideas about ...
