“Shapiro’s book is a promising player in the game of physics texts aimed at the modern student with correspondingly modern interests. … this book has additional mathematical relevance. It is a very solid pedagogical effort, with the various physical themes all carefully worked out, as also the relevant mathematics, of course. Perhaps most importantly, there are many, many problems, and, as always, the student’s mastery of this material is proportional to the number of problems worked.” (Michael Berg, MAA Reviews, September 6, 2021)
