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 ...

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 ...

Energy distribution of atoms in a thermal state. For positive absolute temperatures (upper part, blue), the low energy states have the highest population; for negative absolute temperatures, the high ...

(via SciShow) It's impossible to have something colder than absolute zero...right? That's why it's called "absolute zero". Well, it turns out you can get certain substances to negative absolute ...

In the loop: PhD student Monika Monika takes a closer look at the negative-temperature experimental setup in Jena. (Courtesy: Ira Winkler/University Jena) Researchers in Germany and the US have ...
