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 aim of the paper is to discuss the alleged representational role of Feynman diagrams
(FDs) in the context of quantum field theory and in particular in quantum electrodynamics …

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 …

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 …

A graphical program, suitable for Feynman diagram drawings, is presented. It is mouse
driven and easy to use. It is intended for those physicists who think they spend too much …

I give a brief introduction to how Feynman diagrams are used. I review arguments to the
effect that they are only used as calculation tools and should not be interpreted as …

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 …

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

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 …
