The mathematical theory of stochastic integrals, i.e. integrals where the integrator function is over the path of a stochastic, or random, process. Brownian motion is the classical example of a stochastic process. It is widely used to model the prices of financial assets and is at the basis of Black and Scholes' theory of option pricing.
He invented the theory of quantam electrodynamics

Richard Feynman was a quantum physicist. He worked in the theory of electrodynamics and he helped shape physics as it is known today. Today, physicists look back at him in admiration.
Richard P. Feynman was a theoretical physicist with many discoveries to his credit. Two of his greatest were the theory of quantum electrodynamics, and introducing the concept of nanotechnology.
