Photons: Corpuscles of Light (Part I)
Richard Feynman gives us a lecture on Quantum Electrodynamics, the theory of photons and electron interactions which incorporates his unique view of the fundamental processes that create it.

One of the 3 winners of the 1965 Nobel Prize in Physics for his work, Feynman is an expert on quantum mechanics and developed the path integral formulation of relativistic quantum mechanics used in Quantum Field Theory. He interpreted the Born series of scattering amplitudes as vertices and Green's function propagators in his famous diagrams, the Feynman Diagrams, and also worked on the fundamental excitations in liquid helium leading to a correct model describing superfluidity using phonons, maxons and rotons to describe the various excitation curves. Other fields of work include the Feynman-Hellmann Theorem, which can relate the derivative of the total energy of any system to the expectation value of the derivative of the Hamiltonian under a single parameter (e.g.: volume). He also worked on... (read more)

In this final lecture of the series, Feynman discusses the problems which motivated the development of Quantum Electrodynamics, and further problems in the Standard Model of Particle Physics. This includes the Electroweak Theory developed by Steven Weinberg, Abdus Salam and Sheldon Glashow, describing the change of particle flavour by means of a type of neutral current which is asymmetric in nature (found in the study of neutrino flavour change in neutrino detectors and the helicity of neutrinos from the polarisation of beta decay experiments found earlier by Chien-Shiung Wu and her colleagues) and in the detection of particles which break the symmetry in electrodynamic and weak interactions, namely the Z-boson wose S matrix matches that of a photon at energies exceeding 100GeV, giving the so-called Electroweak Force. Moreover, the theory of Nuclear Interactions, in and of themselves, was discovered prior to this, and the interaction of force-carrier particles in the nucleus...
