Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I bought a book recently of this title. I wanted this one to compliment the field theory book I have already (Peskin and Schroeder) because I find the latter a little hard to follow on my own (I am currently taking Relativistic Quantum Mechanics and will be taking QFT course at some time in the future).

I am always skeptical about these self-teaching series, especially when it comes to quantum field theory. It seems like it goes through all the basic elements of QFT and I can actually read and follow, however there are several obvious typos (such as "charge of strange quark is +2/3") and the author is "a researcher at Sandia National Laboratories".

Does anyone have experience with this book? Should I keep reading, or will I get myself into a whole nonsense about QFT?
