The Lorentz force law

Special Relativity and Electrodynamics (Spring, 2012)

May 14, 2012

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.

  • Review of Einstein & Minkowski notation
  • Introduction to tensors and tensor notation
  • Derivation of the Lorentz force law
