Title: A sloppy job
Product review: The only thing that could possibly justify the word "modern" in the title of this book is that, at the very end, it includes a discussion of supergravity and string theory. Apart from that, both the choice of topics and their treatment are fairly standard. The book is not an "introduction" either; it touches upon quite involved issues in a rather casual way. At the same time, it is sloppy both in its presentation and its notation, and some of the "proofs" leave much to be desired. It reads like something that was written in a hurry, at the expense of clarity and coherence. If one is looking for an introduction, there are far better books around. More advanced readers will be able to find books that cover the same material in a much better way, in the same number of pages.
