An interactive, multimedia website created by physicists at the University of New South Wales, which presents a series of animated guides to Einstein’s theory of special relativity. The guides take the form of six modules which proceed from a discussion of Galilean relativity and mechanics, through a look at Einstein’s theory itself, a consideration of time dilation and a look at the implications of the theory called ‘Beyond Relativity’. Each animation comes with detailed background notes, giving more complete explanations.
