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.
The Feynman gauge is a specific choice of gauge in quantum field theory that simplifies calculations by removing certain mathematical complexities. It helps in making calculations more manageable and allows for easier interpretation of physical observables. By using the Feynman gauge, physicists can more easily predict and understand the behavior of particles and interactions in quantum field theory.

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.
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.
