In theoretical physics,

**Feynman diagrams are**pictorial representations of the mathematical expressions describing the behavior of subatomic particles. While the**diagrams are**applied primarily to quantum field theory, they**can**also be used in other fields, such as solid-state theory.Considering this, what did Feynman do?

Richard Phillips

**Feynman**(/ˈfa?nm?n/; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particleWhat did Feynman die of?

What did Feynman win the Nobel Prize for?

The

**Nobel Prize in**Physics 1965. The**Nobel Prize in**Physics 1965 was awarded jointly to Sin-Itiro Tomonaga, Julian Schwinger and Richard P.**Feynman**"for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles".
