Feynman: space-time methods for quantum electrodynamics

What changed

Perturbative quantum-electrodynamic processes became representable and calculable through a reusable graphical and space-time organization.

Scientific scope

The 1949 paper's method; Schwinger, Tomonaga and Dyson formulations and equivalence results are excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. This entry covers the 1949 paper and its calculational organization. It does not absorb Schwinger’s, Tomonaga’s or Dyson’s separate formulations and equivalence work.
