Series: The Physical Review, Vol. 77, No. 4. Offprint. pp. 536-549. Original printed wrappers. Signed by Pais. Very good. This is one of the first significant papers to use Feynman diagrams in QED calculations, two years after Feynman first demonstrated their utility. / Karplus was a theoretical physicist and leader in the science education field. Early in his physics career, Karplus became interested in developing the theory of quantum electrodynamics while working at Princeton. Due to the ambiguities and complexity of QED, no one had so far been able to do such a calculation. Karplus while in collaboration with Norman Kroll, used QED to calculate the value of the magnetic moment of the electron. This was an extremely rigorous calculation, requiring more than a year of intense efforts from both men; the agreement of their result and the experimental measurements was the first serious confirmation of QED.

Offprint. Originnal Wrappers. Includes Errata slip with 7 corrections. Very good. "[In 1948] Kroll and Lamb and, right thereafter, French and Weisskopf submitted their papers on the Lamb shift. Deftly these authors had managed to obtain correct answers by non-covariant methods. . . With the successful completion of the magnetic momemnt and Lamb shift calculations, a solid beachhead had been established in uncharted terrain, the physics of radiative corrections" :: Abraham Pais, Inward Bound, pp.460-461. This paper represents a significant step in the research which would, 6 years later, result in Lamb winning the Nobel Prize in Physics. Willis E. Lamb was an American physicist who won the Nobel Prize in Physics in 1955 for research related to his discovery of the Lamb Shift. Norman M. Kroll was an American theoretical physicist known for his pioneering research in Quantum Electrodynamics, at the Institute for Advanced Study, went on to become a professor of physics at Columbia and later head of the physics department at UCSD.
