Feynman scattering necklace | gold vermeil pp_render The lymphocyte represents the cellFeynman scattering necklace gold vermeil A Feynman diagram on a chain, in 18K gold vermeil. The geometry is the simplest possible electron photon interaction: two incoming particles, an exchange, two outgoing particles. The diagram is the calculation, not just a drawing of it. The pendant carries that idea at 34 mm. The Science Behind the Scattering Diagram Richard Feynman introduced his diagrammatic notation for quantum electrodynamics in the late
