An introductory textbook in solid state physics for students of physics, materials science or engineering, electronics engineering, and physical chemistry. The book is intended to give a solid conceptual understanding of the ideas that underly the behavior of atoms and electrons in solids. It assumes some introduction to quantum theory, without a requirement of a thorough understanding of the subject - hence the introductory review in the first chapter. The "storyline" of the book begins with the principle ideas of the quantum theory and ultimately leads to the mechanical and electrical properties of metals and semiconductors, semiconductor devices, magnetic materials, and - ultimately - superconductors. The course that "covers" the material of the book could easily stretch over a year. There is no attempt to be all-inclusive in the choice of topics for the book. It is intended to leave the student with a good conceptual overview of the subject - and an appreciation for the interplay between theory and experiment and the interconnections among the many topics that appear in the curriculum of scientists and engineers.
