[College Park, MD]:: The Physical Review, 1950., 1950. 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.
