This book provides a deep understanding of the nature of disordered materials. It will appeal to physicists, materials scientists, advanced students and engineers.

This self-contained text introduces the physics of structurally disordered condensed systems at the level of advanced undergraduate and graduate students.

Clearly presented and amply illustrated it provides stimulating and novel coverage of a difficult area. In this second edition, the treatment of the mode coupling theory of the glass transition has been enlarged and now connects to a new section on collective excitations in disordered systems.
