Understanding Light as a Particle

Physicists lament that no meaningful progress has been made for many years in our understanding of the fundamental forces of the universe. Einstein thought that the answers would be found in an understanding of the nature of light. Feynman said of the double-slit experiment ".......if we could understand what is going on in this deceptively simple experiment, we would penetrate to the heart of quantum theory - and perhaps all its puzzles would dissolve."Both of these ideas are harnessed in this paper to provide an argument that a clear view of the nature of reality is given by an understanding of light propagating as a particle and of the nature of its interaction with the material world.
