Temperature is typically thought of as the average energy of individual atoms or molecules within a given collection. For atoms of similar mass, this "kinetic temperature" would basically be their ...

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 question Is there an opposite to absolute zero? seems innocent enough, right? Absolute zero is 0 on the Kelvin scale, or about minus 460°F. You can't get colder than that; it would be like trying ...

An important mechanism for superconductivity in a metallic compound containing ytterbium, rhodium and silicon, has been uncovered by researchers. The underlying concept of the quantum-critical point ...

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 ...

Tapio Simula receives funding from Australian Research Council (ARC). He is affiliated with American Physical Society (APS). He works for Monash University. The concept of temperature is intimately ...

It is no secret that semiconductor junctions change their behavior with temperature, and you can use this fact to make a temperature sensor. The problem is that you have to calibrate each device for ...

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 ...
