Absolute zero is the lowest theoretical temperature, which scientists have defined as minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius). That's even colder than outer space. So far, ...

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 ...

Science is full of zeroes. Light has zero mass. Neutrons have zero charge. A mathematical point has zero length. Those zeroes might be unfamiliar, but they follow a consistent logic. All represent the ...

THE Science Museum, South Kensington, has recently performed a most useful public service in arranging, in connexion with the Very Low Temperatures Exhibition, for a series of demonstrations and ...
