In thermodynamics, statistical thermodynamics (or statistical mechanics or statistical physics) is the study of the average energy behaviors of large groups of individual particles. [1] Statistical thermodynamics can also be defined as the study of the random motion of molecules by means of statistical methods. [2]
Etymology
The term "statistical thermodynamics" doesn't seem to have come into use until the 1930s, loosely defined as statistical mechanics with more focus on thermodynamics.
Human physics
See main: Human physicsMany authors, in recent years, e.g. those in social physics, have used statistical thermodynamics, such as through the guise of a human particle logic, as a basis to argue or explain various bulk human system behaviors, such as distributions of wealth.
