In case this part wasn't totally clear in the video: for systems where S(E) is monotonically increasing (nearly every system), the slope is always positive, so dS/dE is always positive, so 1/T is always positive. If a system's S(E) function has a negative slope, then that system is capable of negative Kelvin temperatures, specifically, for the energetic states where S(E) slopes downward.

Wow, this short is off to a much slower start than the quantum mechanics one I created recently! Why does the algorithm have no love for statistical mechanics?!😂

I think it's wrong. By definition, temperature related to the motion of particles. If T=0, then there is no motion. If T<0, then there supposed to be negative motion or what?
