Mr Tan, But it should make sense, as the molecules/atoms vibrate or move around, they do so because they have velocity. And when we talk about molecular dynamics wont we say KE = (1/2)mv2 where KE =...

Very interesting topic! I read the first parts of the book Thermal physics written by C.Kittel under the suggestion of Prof. Suo. I post this comment to explain what I learn form that book. First, the...

For a one-atom, or several atoms, system, how are you going to define the “thermal contact”, which is the kernel of the concept of temperature?

But the statistical meaning of the temperature is missing, which is the theme of this series of talk.
View ArticleRe: statistical meaning of temperature
In teaching a course last spring, I updated my notes on temperature. The central aim of the notes is to reconcile the empircal notion of temperature and its statistical meaning. Hope that the notes...

Dear Zhigang, I read your lecture notes on “Statistical Mechanics” posted in http://imechanica.org/node/288. They are very interesting and useful to me. I can understand the effort in reconciling the...

The fundamental postulate is also intriguing. It says that a system isolated for a long time is equally probable to be in any of its quantum states. That our world is described by quantum states may...

When saying that a system needs “a long time” to be in any of its quantum state, there are some questions: 1) How long? 2) If “time” is involved, it seems that a system needs time to evolve from one...

These are excellent questions, but generally useful answers do not exist. They belong to nonequilibrium phenomena. For one class of nonequilibrium phenomena, the system is not in equilibrium as a...

Henry: For an isolated ergodic Hamiltonian system with kinetic energy quadratic in the momenta (all standard assumptions), there is a clear definition of the temperature based on the derived result of...
