“…Before this "spontaneous symmetry breaking” event took place a fraction of a nanosecond after the Big Bang, the electromagnetic and weak forces were unified and elementary particles had no mass; afterwards, the universe was left with a non-zero "vacuum expectation value" that enabled elementary particles to acquire mass and thus for nuclei and atoms to later form. …”

“…Lanczos's quaternionic interpretation of Dirac's equation provides a unified description for all elementary particles of spin 0, 1/2, 1, and 3/2. The Lagrangian formulation given by Einstein and Mayer in 1933 predicts two main classes of solutions. (1) Point like partons which come in two families, quarks and leptons. …”
