This new book on statistical mechanics and thermodynamics is meant for undergraduate physicists and will compete well with such standard textbooks as Statistical and Thermal Physics by F. Reif (McGraw-Hill, 1965) and Thermal Physics by C. Kittel and H. Kroemer (W. H. Freeman, 1980), It will not, as a rule, be of interest for undergraduate chemists because American chemistry curricula usually integrate these topics into a general physical chemistry course.
