The special theory of relativity was first proposed by Albert Einstein in a paper entitled "On the Electrodynamics of Moving Bodies." In it he argues that the previously discovered Lorentz transformation is not just a theoretical curiosity but that it actually couples space and time together in ways that are incompatible with classical theories of physics. The Sync Physlet show above demonstrates one of the consequences of Einstein's theory. It shows how the electric field from a point charge distorts when the point charge undergoes various types of motion close to the speed of light.
