Quantum Field Theory For The Gifted Amateur
Quantum field theory is arguably the most far-reaching and beautiful physical theory ever constructed, with aspects more stringently tested and verified to greater precision than any other theory in physics. Unfortunately, the subject has gained a notorious reputation for difficulty, with forbidding looking mathematics and a peculiar diagrammatic language described in an array of unforgiving, weighty textbooks aimed firmly at aspiring professionals. However, quantum field theory is too important, too beautiful, and too engaging to be restricted to the professionals. This book on quantum field theory is designed to be different. It is written by experimental physicists and aims to provide the interested amateur with a bridge from undergraduate physics to quantum field theory. The imagined reader is a gifted amateur, possessing a curious and adaptable mind, looking to be told an entertaining and intellectually stimulating story, but who will not feel patronised if a few mathematical niceties are spelled out in detail. Using numerous worked examples, diagrams, and careful physically motivated explanations, this book will smooth the path towards understanding the radically different and revolutionary view of the physical world that quantum field theory provides, and which all physicists should have the opportunity to experience.
This wonderful and exciting book is optimal for physics graduate students. The authors are brilliant educators who use worked examples, diagrams and mathematical hints placed in the margins to perfect their pedagogy and explain quantum field theory. They also include exercises with a bibliography, an appendix on complex analysis and a detailed index. The physical explanations are exceedingly well written and integrated with the mathematics. Quantum field theory is the next big thing and this book will help the reader to understand and use the theory. This text presents Lagrangians, Feynman diagrams, path integrals, broken symmetry and renormalization in a clear and concise manner. After getting that background, the reader is shown applications that range from condensed matter physics to the world of particle physics. This book is not for specialists, but for a wider audience that is deeply interested in understanding this amazing physical theory.
Quantum Field Theory for the Gifted Amateur, authored by Tom Lancaster and Stephen J. Blundell and published by Oxford University Press, is a comprehensive book for those who deeply aspire to know more about the universe we exist in. Quantum field theory is perhaps the strongest theory that has explained most of our questions about the universe. Compiled by experimental physicists, the book offers a deep insight to even complex concepts in an easy-to-read and easy-to-understand way. It contains a large number of photos, pictures, and diagrams to explain most of the topics.

I find it counterproductive when people treat the formulation of relativistic QFTs as a matter of second quantization. It confuses learners into thinking that it involves going beyond the general principles of quantum theory. The real change is going from situations where the wave function formulation is often the most convenient (for non-relativistic situations) to a Heisenberg-picture formulation with heavy emphasis on its time-dependent operators.
