I used this book for my course on statistical mechanics. It is a very good introduction to statistical mechanics. The use of lattice model in explaining various topics made it easy for us to understand the underlying concepts. It starts with a simple introduction to probability, equilibrium, math tools such as series and approximations, and then goes on to Boltzmann distribution law, entropy, free energies, statistical mechanics, phase transitions, the details of how water is different from other substances, polymer solutions etc. I liked the some of the chapters discussed in the book like the entropy, free energy of mixing, phase transitions and the topics on water because of the way they were interpreted in detail. I was fascinated by the anamolous properties of water due to its hydrogen bonding network explained using statistical thermodynamics. The chapters were well divided into microscopic and macroscopic properties of various substances.This book is a very good book for beginners tol earn about statistical mechanics. I had previous knowledge about many of the concepts discussed but still I liked the way the author explained the different concepts using various models. But I thought that the exercise problems towards the end of each chapter were a bit confusing due to the lack of sufficient information in some of the problems. Other than that the book was really good.
