✦ Synopsis

Before we quantize fields, we need to understand the Lagrangian formalism and derivation of invariants when the Lagrangian respects a certain symmetry. Important invariants are the energy-momentum and the electric charge, whose underlying symmetries are translational invariance in space-time and gauge invariance.
