Oberholtzer, Publications of the National Bureau of Standards: Published by NBS July 1960 through June 1966; Published by Others 1960 through 1965 (with Subject and Authors Indexes) (National Bureau of Standards Supplement to Miscellaneous Publication; 240), [Washington, D.C.]: National Bureau of Standards, United States Department of Commerce, OCLC 233090333, page 145:
- The symbolic representation of Maxwell's equations is introduced to make it easier to survey the whole subject and to formulate the equations. The Feynman diagram method is applied to the computation of the correlation of the fields at different points in space to any order of approximation.

- Among physicists, Feynman is probably best known for Feynman diagrams, the work that brought him his Nobel Prize in 1964. The diagrams constitute a computational tool kit that enables physicists to make sense of not only Quantum Electrodynamics, the theory that underpins electricity and magnetism, but also of the relativistic quantum field theories believed to describe the weak and strong interactions of elementary particles.
