In this paper, the author shows how the partial differential equations governing a centrally important segment of relativistic quantum electrodynamics--namely radiative corrections introduced by the quantization of the electromagnetic radiation field--in its simpler aspects can be derived by a novel and very elementary means. The method consists in employing the Schrodinger-Jordan rule to a classical relativistic Hamiltonian and then "symmetrizing" to exploit a special characteristic of the Hamiltonian. This leads very straightforwardly and almost painlessly to an equation that contains a very large number of the differential equations proposed in the literature for spin 1/2 (and spin 0) particles, including those differential equations governing an important part of quantum electrodynamics. 15 pp. Ref.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
