I want to know the answer to the following question:
Feynman proposed a integral model in particle physics, what was it?
All the background I'm provided with is that "Richard Phillips Feynman (/ˈfaɪnmən/; 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 particle physics for which he proposed the parton model.". Is that enough to answer the question?
Answer: yes
