Here two Russian theoretical physicists give a lighthearted presentation of the special theory of relativity. It is so simply written that the reader needs no technical knowledge beyond arithmetic. Their witty text, illustrated by a series of Russian cartoons, explains the paradoxes of relativity--its funny trains, contracting rulers, and capricious clocks--in a charming way.
