At the 1948 Pocono conference on quantum physics, the young theoretical physicist Richard
P. Feynman presented a new pictorial way to analyze scattering processes in quantum …

The aim of the present paper is to analyze Feynman diagrams within the context of recent
historical and philosophical debates about models in science and against the backdrop of …

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 …

What is the material world around us made of? The answer depends on whom and when
you ask. A century ago the strongest answer would have come from the chemists. For them …

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 …

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 …

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 …

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 …

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 …

We introduce a novel compositional description of Feynman diagrams, with well-defined
categorical semantics as morphisms in a dagger-compact category. Our chosen setting is …
