(Nanowerk News) 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 surprising in summer. On the ...

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 ...

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 ...

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 ...

Those who have studied some physics might remember why minus 459.67 Fahrenheit is called "absolute zero," but for the rest, it's probably a bit confusing. Switching to Celsius won't help; absolute ...

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 ...

Right now, as I type this sentence, Earth’s Northern Hemisphere is tilted away from the bright ball of light that is the Sun, and it’s cold here (relatively speaking). Humans have long recorded and ...
