In my 35 years in physics, this is one of the very best textbooks that I have come across. If you’re interested in elementary particle theory, you’ll do yourself a huge favor to read this book. It provides a wonderfully approachable introduction to a rather esoteric and demanding field of physics, and I guarantee you’ll keep it, and continue to consult it, as you progress.<br>Anyone who ever wrote even a tutorial review article, let alone a textbook for students, appreciates the difficulties this involves. Professionals who wrote a lot of papers but never taught any class themselves tend to scoff at this notion, but personally mastering a subject is one thing; being able to teach it effectively to students requires considerable additional skills above and beyond being a subject matter expert.  And when it comes to teaching, Griffiths’ book is just about as good as it gets. Of course, the book is for (upper!) undergraduates. But its level has little to do with the fact that this is an exquisitely well written student text! Profs who think about writing particularly graduate texts would do very well to study the deeper didactic devices Griffiths uses and learn from his style. Students the world over will thank you for it – and are much more likely to buy your book!
