In a detailed reconstruction of the genesis of Feynman diagrams the author reveals that their
development was constantly driven by the attempt to resolve fundamental problems …

George Gamow, the wisecracking theoretical physicist who helped invent the Big Bang
model of the universe, was fond of explaining what he liked best about his line of work: He …

The way from the path integral to Feynman diagrams is sketched. The emphasis is put on
the decrease of complexity in this process, from infinite-dimensional integrals down to the …

This paper aims to give a substantive account of how Feynman used diagrams in the first
lectures in which he explained his new approach to quantum electrodynamics. By critically …

Feynman diagrams (hereafter FDs) are now iconic. Like pictures of the Bohr atom, everyone
knows they have something important to do with physics. Those who work in quantum field …

There are two distinct interpretations of the role that Feynman diagrams play in physics:(i)
they are calculational devices, a type of notation designed to keep track of complicated …

Feynman diagrams have revolutionized nearly every aspect of theoretical physics since the
middle of the twentieth century. Introduced by the American physicist Richard Feynman …

Analytic Properties of Feynman Diagrams in Quantum Field Theory deals with quantum field
theory, particularly in the study of the analytic properties of Feynman graphs. This book is an …

This book has been developed from the lecture notes of a course in Advanced Quantum
Mechanics given by the authors at the Politecnico of Torino for students of physical …

This book provides an easily accessible introduction to quantum field theory via Feynman
rules and calculations in particle physics. The aim is to make clear what the physical …
