After a review of Einstein & Minkowski notation and an introduction to tensors, Professor Susskind derives the relativistic Lorentz force law from the Lagrangian for a particle in a vector field. At the end of the lecture, he introduces the the four fundamental principles that apply to all of modern physics: stationary action, locality, Lorentz invariance, gauge invariance.
