A UNIFYING PRINCIPLE OF INTERACTIONS
K. E. Eriksson · Arkiv Fysik · 1964
A unifying principle for all interactions is suggested with Coulomb's law as a model. If this principle is correct, the problem of finding the fundamental interactions is reduced to the problem of finding the sources of interaction. The principle states that the sources of interaction are real conserved quantities. Einstein's theory of gravitation and the theory of electrodynarnics follow from the principle if the energy momentum density and the electric current density (multiplied by suitable constants) are recognized as sources of interaction. The fundamentals of a theory for a massless spin-1/2 particle in interaction with the gravitational and electromagnetic fields are outlined. (auth)
