Unlike its lengthy competitors, this compact text/reference provides students, practicing engineers, and scientists with the complete physical laws from classical mechanics to the quanta optics and semiconductor physics. Tasks, projects, and experiments are integrated throughout each chapter so the reader can test the theories as they are presented. Because of its breadth of topics, the book can be used as a refresher for engineering licensing exams or as a full year course. It emphasizes only the level of mathematics needed to master concepts and conduct experiments used in industry. Moreover, the book is especially suited for self-study because of its readable, concept-task-experiment structure.
