FEYNMAN, Richard P.
Mathematical Formulation of the Quantum Theory of Electromagnetic Interaction. pp. 440-457 in Physical Review, Vol. 80, No. 3, November 1, 1950. RIGOROUS PROOF OF THE FEYNMAN RULES
Lancaster, PA & New York, NY: American Physical Society, 1950. First edition, journal issue in original printed wrappers, of Feynman's paper providing a rigorous justification and proof for his famous "Feynman diagrams" and "Feynman rules" in quantum electrodynamics. "While Feynman made many original and imaginative contributions to theoretical physics, it may well be that his place in the history of science will be largely based on his approach to renormalizing quantum electrodynamics, and especially on the tools that he invented to accomplish that goal, such as path integrals, the operator calculus, and the famous Feynman diagrams" (Selected Papers, p. 7). "Nobody but Dick [Feynman] could use his theory, because he was always invoking his intuition to make up the rules of the game as he went along. Until the rules were codified and made mathematically precise, I could not call it a theory" (Freeman Dyson, quoted in David Kaiser, Pedagogy and the Practice of Science). "In the [present] paper Feynman used the methods of his Ph.D. thesis and his 1948 paper in the Reviews of Modern Physics ['Space-Time Approach to Non-Relativistic Quantum Mechanics'] to derive the basic equations and principles of his method . . . In ['Mathematical formulation . . . '], Feynman established the validity of the rules given in previous papers for the solution of problems in quantum electrodynamics. Starting with Fermi's formulation of the field as a set of harmonic oscillators, he integrated out the effect of the oscillators in the Lagrangian form of quantum mechanics. There resulted an expressi … [Click Below for Full Description]
