This new book is a thoroughly modernized and doubled-in-size version of a text by JDP (Introduction to Solid State Theory) published a number of years ago. It has grown out of over 30 years of teaching solid state physics and is conceived as an introduction and textbook for actual, as opposed to ideal, students and prepare them to study the literature and begin a life-long learning experience. While the standard solid state topics are covered, the basic ones often have more detailed derivations than is customary. Crystalline solids are emphasized. Several recent topics are introduced, as are some subjects normally included only in condensed matter physics. Lattice vibrations, electrons, interactions, and spin effects (mostly in magnetism) are discussed the most comprehensively. The book is intended for beginning graduate students as well as certain well prepared undergraduates but is also useful to graduate students in electrical engineering, metallurgy, and materials science. Many problems are included whose level is from "fill in the steps" to long and challenging, and the text is equipped with references and several comments about experiments with figures and tables.
