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 ...

(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 ...

One of the firmest hitching posts in science is absolute zero, the temperature ( -273° C. or 0° Kelvin) where vibratory motions of the atoms cease. Generations of physics students have been told that ...

How would you go about determining absolute zero? Intuitively, it seems like you’d need some complicated physics setup with lasers and maybe some liquid helium. But as it turns out, all you need is ...
