Description

A macroscopic system consists of a tremendous number of microscopic atoms and molecules. In thermal equilibrium the state of such a system is uniquely defined, despite the fact that the microscopic particles behave quite randomly. This observation gives rise to the fundamental law of the statistical physics; it allows entropy to be defined and a framework for the theory to be constructed. The first part of this book explains the essence of statistical physics without going into details such as Liouville�s theorem or ergodic theorem, which are difficult for beginners and unnecessary for actual application of the statistical mechanics. In the second part, statistical mechanics �s applied to various systems which look different but have the same mathematical structure. In this way readers can deepen their understanding of statistical physics.Typham this is the title: Statistical Physics An Introduction
