A textbook for a sophomore or junior course for students who have already completed a calculus-based introductory course in classical physics and have some familiarity with partial derivatives. Introduces a wide range of physical principles that have developed in the past century and demonstrates with examples and exercises how to apply them quantitatively in all areas of natural science as well as more advanced physics. Seeks to maintain a consistent approach and level of sophistication, and slows down to clarify the points that are counter- intuitive and that students often misunderstand.
