The aim of this new book is identical to that of the first edition, that is, to provide an introduction to the chemistry and physics of solids that will act as a foundation to courses in chemistry, engineering, materials and physics, with a bias towards the materials spectrum..   Since the first edition there has been a greater and greater emphasis on the use of computing methods in the solution of complex problems in solids. A primary objective is to introduce more on recent computer studies of materials problems. As well as this, there have been vast developments in the last ten years in areas such as battery technology, solar cells, lighting technology, lasers, microelectromechanical devices (and comparable nano versions of these), graphene and graphene electronics, carbon nanotube electronics, the Fukashima nuclear disaster.   New to this edition: Every chapter will be rewritten completely, diagrams modified and these reduced in number where possible. New material and essential text from the Supplementary Material section will be incorporated into the existing chapter structure. Existing problems will be edited and new problems included.   (With more on website.) The introductory questions and subsequent answers will be omitted as this duplicates existing text.
