## Special Relativity and Electrodynamics

**Special Relativity and Electrodynamics (Spring 2012, 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. He also covers the work of the German mathematician Hermann Minkowski.
