Lagrangian for the Dirac Equation | Non-Interacting | Relativistic Quantum Mechanics
In this video, we show you the Dirac Lagrangian for the non-interacting case (=no electromagnetic fields) of describing spin-1/2 particles in #QuantumMechanics! If you want to read more about the Dirac Lagrangian, we can recommend the book „An Introduction to Quantum Field Theory“ by Mic

There is a wholly alternative method for considering the time evolution of a system, not invoking causality or determinism, i.e. cause and effect or force and acceleration. Without using the laws of Newton we can use the principle of extremum (minimum) action to derive equations of motion
