This book is not good. The chapters are extremely short, and as a result the entire book is weak. There are very few connections between equations. At times, it seems as if Yoshioka pulls the equations (and material) out of thin air. Some of the equations he puts in are also of rare form and, in my experience, nearly useless in learning Statistical Mechanics.

I am forced to use this book for a graduate level Statistical Mechanics course, and I find myself running back to my undergraduate text, Daniel Schroeder's 'Thermal Physics' for reference to EVERYTHING that Yoshioka has missed (which is just about everything important for developing a good sense of stat mech).

I would heavily NOT recommend this book for anyone, student, teacher, or self learner. There are far better books to use than this one.
