Statistical Mechanics by Kerson Huang is a comprehensive textbook on the framework of statistical mechanics, in which the macroscopic thermodynamic behavior of complex systems is explained by the application of probability and statistics to the dynamics of their microscopic constituents. The book is directed mainly at advanced undergraduate physics majors, graduate students in physics, as well as researchers in the field. This adaptation of the second edition of the textbook is a revision that has been developed from detailed feedback obtained from long-standing users in India.
