Quantum Field Theory: The Why, What and How (Graduate Texts in Physics) 1st ed. 2016 Edition

I love this book. The first chapter is totally amazing, it explains many doubts that I had about quantum field theory. The beauty of this book resides in its different approach to explain the concepts of quantum field theory. It is not only "shut up and calculate," it is about the conceptual foundation of this topic, and that is the key for me.My recipe to learn quantum field theory (At least, until quantum electrodynamics) is this books plus student friendly quantum field theory (Klauber). Padmanabhan's book puts more emphasis on path integral formulation. On the contrary, Klauber's book is about canonical quantization. Therefore, with these two books, you can dominate both formulations, and you will be prepared for gauge theory and the standard model. (QCD and electroweak interaction).There are many books about QFT, but most of them are a waste of time from my point of view. Why did I want to learn from old and non-pedagogical books if I have these fantastic books?

I would give Six stars to this book id f this was permitted. The first chapter of the book explains non-relativistic quantum mechanics both in term of Hamiltonian formalism and path integral. I have never seen a better exposition than this before. The book then moves to relativistic quantum mechanics and then to quantum field theory. Here we learn why these theories have to be like they are. Fantastic book

Everything OK !

great book

Refreshingly different approach to QFT! This book is a unique combination of mathematical rigor and conceptual insights. Rather than taking the usual mundane route to QFT i.e. classical fields -> canonical quantization -> interacting fields -> renormalization, this book first answers the fundamental question - "why fields?". This is done beautifully by evaluating the path integral for a relativistic particle and showing that interpretation of the resulting propagator in terms of objects known as "fields" is inevitable. In my opinion, this is by far the best possible way to "directly" transition from a course in quantum mechanics to QFT. Path integrals, Functional menthods and the Wilsonian interpretation of QFT are all emphasized from the start. The highlight being - all of these concepts made completely accessible at the master's/early graduate level. I wish I had access to such a book when I started with QFT. Highly recommended!!
