This web site contains a detailed introduction to relativity. It integrates text explanations of relativity concepts with diagrams and animations to clarify the material. It includes a historical perspective, the basics of spacetime, special relativity, and general relativity. The approach is non-mathematical throughout.
Editor's Note: This resource provides a foundation to understand how relativity theory has evolved from the Aristotelian and Galilean views through Maxwell's Electrodynamic Theory of Light, culminating in Einstein's theories. It could be a refresher for teachers or a tutorial for students who have completed a year of high school physics.
