There is on the other hand, such thing as negative temperature. You might enjoy reading about entropy and statistical mechanics.
I though 0 Kelvin was theoretically impossible to get to as a direct consequence of the uncertainty principal? If that's so that how can negative temperature exist if 0 Kelvin is the point where all motion stops. Or did I miss something somewhere?
Well I'm assuming that he means that at -X Kelvin, motion would not only cease to progress, but will regress. Theoretical of course.

a negative temperature????!!! that's impossible since the entropy is positive!
