Starting with simple inter-atomic forces between two atoms and progressing through to bulk magnetic properties of solids this book is THE book for undergraduates studying the physics of gases, liquids or solids. The author presents the content clearly and without resorting to unnecessarily complex mathematics, a good thing for most students! As an example of the progressive structure of the book, the treatment of gases progresses from simple models, which students should recognise from earlier study, to the more rigorous models taught in physics degrees. It then continues onto the topic of complex transport properties. All areas are explained in such a way deeming them very understandable. Not only have I been recommending this book to my first year students, at the University of Cambridge, since I started teaching them but I regularly use it as a reference in the course of my own research.
