Special Relativity and Electrodynamics

Special Relativity and Electrodynamics (Spring 2008, Stanford Univ.). Instructor: Professor Leonard Susskind. In 1905, while only twenty-six years old, Albert Einstein published "On the Electrodynamics of Moving Bodies" and effectively extended classical laws of relativity to all laws of physics, even electrodynamics. In this course, we will take a close look at the special theory of relativity and also at classical field theory. Concepts addressed here will include space-time and four-dimensional space-time, electromagnetic fields and Maxwell's equations. We will also encounter the work of the German mathematician Hermann Minkowski.
