Be careful which edition you use: get the revised second edition!I found the first edition in a used bookstore for dirt cheap. (I understand now why the first edition was so cheap: it's riddled with typos.)As I worked through it, I redid every calculation myself (with the book closed, naturally). But I'm a little rusty with some of the math. So when I finished reproducing the calculations, sometimes I got different results.I was flustered, especially with the calculation to get from eq (2.72) de [...]
Excellent overview for both topics! I really liked this book. I also recommend for the basic and intermediate topics Lancester's book (Quantum Field Theory for the Gifted Amateur book).
