Four equations, one field — Lorentz-covariant, the root of relativity
maxwell
The four equations (Gauss, no monopoles, Faraday, Ampere-Maxwell) become a single relativistic equation, and their invariance - the constancy of c in every frame - is exactly what forced special relativity. The electromagnetic field has a Lagrangian, so it rests on the Lagrangian floor.
