Quantum Mechanics and Path Integrals
Richard P. Feynman, Albert R. Hibbs

The fundamental physical and mathematical concepts which underlie
the path integral approach to quantum mechanics were first developed
by R. P. Feynman in the course of his graduate studies at Princeton,
although more fully developed ideas, such as those described in this
volume, were not worked out until a few years later. These early
inquiries were involved with the problem of the infinite self-energy
of the electron. In working on that problem, a least-action prin-
ciple using half advanced and half retarded potentials was discovered.
The principle could deal successfully with the infinity arising in the
application of classical electrodynamics.
