In this appendix, we summarize the background elementary classical physics that we need to start the study of quantum mechanics in this book. Other physics is introduced as required throughout the book. Probably, the student has already seen most of the physics here before, but this appendix reviews the key items and notations.
B.1 Elementary classical mechanics
As we study quantum mechanics, some of the concepts and relations from elementary classical mechanics remain quite useful. In particular, the ideas of energy, momentum, and mass remain central concepts in quantum mechanics, especially in the nonrelativistic quantum mechanics that is the subject of this book.1
Elementary classical mechanics is sometimes called ...
