An updated edition of a classic of popular science. Leading science writer Nigel Calder, author of Magic Universe, 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 and launched his theory of relativity. Calder explains the mind-boggling ideas of relativity in a way every reader can understand, and provides a new chapter detailing discoveries in the years since his book first appeared.
