As a physicist who has spent several decades in industry and only used statistical mechanics occasionally, I have lost track of new textbooks on the subject. For 25 years I was president of Data Transport Systems Inc in New York City and occasionally held visiting positions at many research organizations, including the Institute for Advanced Study in Princeton, New Jersey, and CERN. Now, retired to resume an academic life, I find it a pleasant task to browse new books.

My first task is to choose a textbook for a graduate course in statistical mechanics; the second, to locate a textbook that also helps define new research directions.

The first task, on pedagogy, is straightforward. I was educated in statistical mechanics, and among the traditional textbooks I used were Fundamentals of Statistical and Thermal Physics (McGraw-Hill, 1965) by Frederick Reif and Statistical Mechanics (Wiley, 1963) by Kerson Huang. Compared with those texts, Equilibrium and Non-Equilibrium Statistical Thermodynamics by Michel Le Bellac, Fabrice Mortessagne, and G. George Batrouni is thoroughly modern. It offers several examples in which classical concepts are applied or expanded in light of recent developments: Analyses of critical phenomena are discussed and extended to incorporate broken symmetries and renormalization groups; quantum statistics, a staple of old textbooks, is applied to quark–gluon plasma; and Monte Carlo techniques are extended for bosons and fermions.

The modernity of the text is also illustrated in the numerous exercises in each chapter, posed for students and faculty. The exercises cover topics on the contribution of nuclear quadruples to specific heat, the Ginzburg–Landau theory of superconductivity, the equilibrium radius of a neutron star, Landau diamagnetism, the ultra-relativistic fermion gas, superfluidity for hard-core bosons, and the quantum Hall effect. In addition, the book contains enough traditional exercises, such as calculating specific heats for a rod (chapter 1) and calculating the partition function for atoms and spin systems (chapter 3), to keep students busy. For a physicist teaching up-to-date thermodynamics and statistical mechanics for the first time, the book effectively creates a good lesson plan.

The second task—finding a book that connects speculative research to what is solidly established in the field—is not as straightforward as the first. For example, suppose someone attempts to define equilibrium and steady states of turbulent systems as they relate to generally accepted fundamentals of ensemble theory and hydrodynamics. How could he or she explain the limiting behavior of such systems when mention of turbulence is absent? In fact, Equilibrium and Non-Equilibrium Statistical Thermodynamics , like many other books on statistical mechanics, does not address the question of turbulence in ensemble theory and hydrodynamics. Nonetheless, the book provides an adequate reality check for those who realize that such attempts to define equilibrium and steady states of turbulent systems must reduce to well-known nonequilibrium concepts, such as transport theory and the Kubo approach. Thankfully, the bibliography includes enough links to the literature on modern nonequilibrium statistical mechanics.

After conducting an informal survey of some of my colleagues in the US, I found that, to my pleasant surprise, the textbooks by Reif and Huang are still classic choices for graduate-level texts on statistical mechanics. I would be inclined to use Equilibrium and Non-Equilibrium Statistical Thermodynamics as a modern pedagogical graduate textbook. It is less strong as a guide for researchers, but not without merit.
