During the Second World War he completed his doctorate on the principle of least action in quantum mechanics, from which later came his formulation of the path integral and his powerful

Feynman diagrams, and he worked on the Manhatten Project which produced the first atomic bomb.

In the 1992 edition of his book A Guide to

Feynman Diagrams in the Many-Body Problem, physicist Richard Mattuck compares the dilemma to trying to describe a galloping horse and all the grains of dust that it kicks up.

Indeed, it is almost de rigueur to begin any treatment of

Feynman diagrams by marveling at their ubiquity, and Adrian Wuthrich's The Genesis of

Feynman Diagrams makes no exception.

Perhaps, Krauss could have drawn

Feynman diagrams to trace the paths of modern physics?

It explains the basic physics and formalism of the theory, helps students become proficient in perturbation theory calculations using

Feynman diagrams, and introduces gauge theories that are playing a central role in elementary particle physics.

Perhaps the finest grained evidence here comes from the work of David Kaiser, who has traced the flow of ideas among physicists, looking at the development, mutations, and spread of

Feynman diagrams.

one can recur to Geometric Probability to assign proper geometrical measures to

Feynman diagrams, not unlike the Twistor-diagrammatic version of the Feynman rules of QFT.

Feynman diagrams of the various processes involved in the Bernard et al.

Richard Feynman, a brilliant physicist who gave his name in mathematics to the

Feynman Diagrams, first presented his new theory of quantum electrodynamics at this 1948 meeting.

Physics is not just an aimless, random sequence of

Feynman diagrams and symmetries, and mathematics is not just a set of messy equations, but rather physics and mathematics obey a definite symbiotic relationship.

Feynman's scientific work (his path-integral formulation of quantum mechanics, his contributions to quantum electrodynamics and the ubiquitous

Feynman diagrams, his work on liquid helium and on the structure of nucleons) is also skillfully treated.

Readers are supplied with an accessible approach to standard elements of probability theory such as the central limmit theorem and Brownian motion as well as remarkable, new results on

Feynman diagrams and stochastic integrals.
