And God said “Let there be fields, an electrical field and a magnetic field.” And there were fields, and it was good. And God said “Let the electrical and magnetic fields have zero divergence. And let the curl of the electrical field be the negative of the change of the magnetic field with respect to time.” And it was so. And God said “Let the curl of the magnetic field be the product of the permittivity and permeability of the void with the change of the electrical field with respect to time.” And, lo, there was light. Who needs it???
