Temperature as a game of marbles: The Boltzmann distribution states how many particles have which energy, and can be illustrated with the aid of spheres that are distributed in a hilly landscape. At ...

A single particle has no temperature. It has a certain energy or a certain speed - but it is not possible to translate that into a temperature. Only when dealing with random velocity distributions of ...

Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now ...
