The story of Special Relativity as we understand it today was written by Albert Einstein. This site recounts Einstein's childhood, his life and his work. In 1905, Einstein worked on three great ideas: Brownian Motion (kinetic atomic theory), the Photoelectric Effect (Quantum theory) and Special Relativity. He eventually received the Nobel Prize for Physics in 1921 for his work on the Photoelectric Effect.

Fly a little green man (NASA-speak: LGM) at very high velocity and watch his moving clock and clocks in a stationary frame of reference.

Herr Fendt has a collection of physics applets on his site.
