Sin-Itro Tomonaga

Physics

Sin-Itro Tomonaga shared the 1965 Nobel prize in physics with Richard Feynman and Julian Schwinger "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles.” Sin-Itiro Tomonaga started his physics career as an assistant to Dirac, who was not satisfied with his formulation of relativistic quantum mechanics. Tomonaga’s contributions to the formulation of quantum electrodynamics (QED) most notably applied a transformation that corrected for one theory of relativistic quantum mechanics, obtaining the same results as Schwinger.
