He predated the discovery of quarks and gluons in his (*) parton model.
An interpretation of electrodynamics that starts from requiring that solutions to the field equations be time-inversion symmetric is named for this physicist and for John Wheeler. Divergences in an approach to quantum mechanics he developed were resolved by a method of renormalization he developed with Schwinger and Tomonaga. He predated the discovery of quarks and gluons in his (*) parton model. One construct named for this physicist provides a way to rewrite a Dyson series and depicts photons as wavy lines. For 10 points, name this physicist responsible in large part for the path integral formulation of quantum mechanics and for a graphical representation of particle interactions, his namesake diagrams.
