This book provides a classical physics-based explanation of quantum physics, including a full description of photon creation and annihilation, and successful working models of both photons and electrons. Classical field theory, known to fully describe macroscopic scale events, is shown to fully describe atomic scale events, including photon emission and annihilation. As such the book provides a ‘top-down’ unification of electromagnetic and quantum theories.

Keywords:Photon;Spontaneous Emission;Absorption;Entanglement;Electron;KinematicKey Features:No other book provides a classical physics-based explanation of quantum physics, including photon creation and annihilation, photon structure and behavior, and electron structureDescribes a zero-Q radiation field with the electromagnetic and kinematic properties of a photon. The continuum field solution that describes a photon enables us to construct a viable electron model sufficient to create photon exchanges and a photon model that, in turn, is sufficient to understand why photons diffract and reflect light as a wave but are created and annihilated as a particle
