A non-mathematical introduction to Einstein's relativity theory. With the aid of 3D rendered graphics the theory is presented in a form that takes advantage of your ability to interpret and retain visually dynamic information. It makes the counterintuitive concepts of relativity seem a little more palatable. A short video showcases the graphics used in the course. The general topics covered are listed here

The Axioms

The two principal axioms of special relativity are explained and given historical context.

Using the axioms it is shown how the theory proved that time must run slow in anything that is moving relative to you.

Time Dilation

We apply the axioms to conclude that time much run more slowly in anything that is moving relative to you. We will look at how this time dilation effect was experimentally confirmed and how it can be applied to explain some naturally occuring phenomena.

Length Contraction and Lose of Simultaneous Events

The length of an object contracts in the direction of motion. The object would reduce to zero length if it could reach the speed of light. We explore how length contraction is a requirement of the axioms. The theory also describes how the concept of now is relative.

Energy, Momentum and Mass

We look at light, its relationship with energy and the Doppler Effect. Energy and Mass are explored and their intrinsic relationship through E=mc

^{2}.Understanding Relativity 2

The follow on course introduces General Relativity.
