An updated edition of a classic of popular science. Leading science writer Nigel Calder, author of Magic Cosmos, wrote Einstein's Universe to mark the centenary of Einstein's birth in 1979. Now it is reissued to celebrate the centenary of Einstein's 'miraculous year' in 1905, when he wrote five astonishingly original scientific papers, culminating in the special theory of relativity. Calder outlines this great theory in a way every reader can understand, and provides a new chapter detailing experiments on relativity in the years since his book first appeared.
