In this paper I propose a model for a physical explanation of the structure of the electron and the photon. The model explains what the charge of an electron is and why it has a total angular momentum of √3/2 ħ. It suggests what the nature of inertial mass is and explains the spin value of ħ for the photon as well as the origins of its alternating electric and magnetic fields. It includes explanations for what static electric and magnetic fields are and why the stress energy tensors for these fields used in General Relativity have the form that they do. It also explains the Lorentz force and the Stern Gerlach force. It gives a physical interpretation of Planck’s constant and proposes a physical mechanism for gravity which explains why it is so weak compared to the electric force. It also explains why the relativistic energy momentum formula has the form it does and also proposes a physical mechanism to explain the deBroglie wavelength of a particle.
