Abstract. This paper (1) augments Pauli matrices to three by three with the interpretation of rigid motions in three spaces, thereby re-examines Dirac spinors, (2) distinguishes the electromagnetic wave energy density term in the Lagrangian of the Standard Model that contains symmetric electromagnetic fields from the asymmetric electromagnetic fields in Maxwell equations, and therefore questions if the Lagrangian of the Standard Model actually contains electromagnetic interactions, wherein the sideways magnetic force and the radial electric force are fundamentally different, and (3) re-interpret the weak and the strong nuclear forces, where we give a simple proof of the CPT theorem and the consequent baryon asymmetry.
