A reissue of a classic book, newly edited, corrected and typeset, with index added. This textbook for undergraduates covers the standard topics in statistical physics but with examples from the medical and biological sciences. Each of the three volumes, the others covering mechanics and electricity and magnetism, can be used independently, and together cover all major topics in physics.
