With the ownership rubberstamp of physicist "Christian Moller" (1904-1980, Danish chemist and physicist who made fundamental contributions to the theory of relativity, theory of gravitation and quantum chemistry.")--Wikipedia [++] Feynman's paper offering the proof for "Feynman diagrams" and "Feynman rules", quietly referred to in the abstract as "The validity of the rules given in previous papers for the solution of problems in quantum electrodynamics is established". "Mathematical proof of the validity of the Feynman rules for calculations of amplitudes in QED."--Particle Physics: One Hundred Years of Discoveries:  "In 1965 Feynman was awarded the Nobel Prize along with Schwinger and Tomonaga "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles"--Nobel Foundation This was sort of--the ending-alpha and omega of RPF's published work in QED. (See Schweber, S.S., "QED and the men who made it: Dyson, Feynman, Schwinger, and Tomonaga".).

Soft cover. Zustand: Very Good. 1st Edition. FIRST EDITION IN ORIGINAL WRAPPERS of Feynman's paper providing a rigorous justification and proof for his famous "Feynman diagrams" and "Feynman rules". "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 Physical Review, Volume 80, Second Series, Number 3, November 1, 1950, pp. 440-457. Lancaster, PA and New York: for the American Physical Society, 1950. Quarto, original wrappers. A nearly invisible spot of dampstaining on the extreme outer edge of some pages (far from text); otherwise fine. Rare in original wrappers and without any institutional stamps.

1st Edition. FIRST EDITION of Feynman's proof of the validity of his 1949 "reformation of quantum mechanics itself," work that would "elegantly rewrite quantum theory" (American National Biography; Peacock, The Quantum Revolution, 102). ALSO included is Erwin Hahn's "Spin Echoes," the first detection and report of spin echoes in nuclear magnetic resonance (NMR). FEYNMAN PAPER: In this, the third paper in his pivotal reformulation of quantum mechanics, Feynman provides the mathematical "proof of the validity of the [his] rules for calculations of amplitudes in quantum electrodynamics. Feynman's paper rigorously proved that his treatment of "the problem of molecular forces from a thoroughly quantum-mechanical point of view" was accurate (DSB). Feynman had arrived "at a simple means of calculating the energy of a molecular system that continues to guide quantum chemists" (ibid). In 1965 Feynman was awarded the Nobel Prize along with Schwinger and Tomonaga "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles" (Particle Physics, One Hundred Years of Discoveries, 113). HAHN PAPER: Erwin Hahn's "Spin Echoes," relays the first detection and report of spin echoes in nuclear magnetic resonance (NMR)."In magnetic resonance, a spin echo is the refocusing of spin magnetization by a pulse of resonant electromagnetic radiation. Modern NMR and magnetic resonance imaging make use of this effect. Echo phenomena are important features of coherent spectroscopy which have been used in fields other than magnetic resonance including laser spectroscopy and neutron scattering" (Wikipedia). In 1950, Hahn, then a graduate student, was experimenting with NMR using pulsed RF energy and observed echo signals, hereafter called 'Spin Echo' or 'Hahn Echo' signals.
