Fundamental Interactions

Abstract

The concept of the photon and its interaction with matter contains maximum information on the unity of physics and on the fundamentals of all elementary states of matter. Just as the classical electromagnetic field was the basis of special relativity the concept of the photon laid the foundations of quantum theory. The interaction of photons with matter is the best understood subject in physics. We may expect the same particle to play a major role in building a quantum theory of elementary particles. The current theories have demonstrated the crucial role of the ideas of symmetry and in particular of broken symmetries in the analysis of the basic states of matter. Therefore we must formulate the electromagnetic theory on the basis of broken symmetries. The implimentation of such a program in a unique way can provide a natural basis to discover the broken internal and space-time symmetries for all other massless as well as massive states of matter in the small.
