2008-10-21 Not the best book on QFT but worth considering

I agree with the (so far) two other reviews to some extent, especially about the typos! And if you're looking for a deep insight into QFT and you are a recent graduate or have studied Quantum mechanics recently, then yes, there are many other better books. That said, for someone like me - starting an MSc after 20 years away from physics - I found it easier to understand at the most basic levels than other more advanced books where my eyes were glazing over by page 2 - and so this is bridging my gap quite well. Def buy other books, but don't pass on this one if you need the basics with a pinch of salt...and its cheap!
