In 1915, Albert Einstein unveiled his masterwork - a theory, in his words, 'of incomparable beauty': the General Theory of Relativity. It is sometimes overshadowed - wrongly, argues John Gribbin - by his work of 1905, the Special Theory of Relativity and E = mc².

In 1915, Albert Einstein presented his masterwork to the Prussian Academy of Sciences: the General Theory of Relativity. It described the evolution of the Universe, black holes, the behaviour of orbiting neutron stars - it even suggested the possibility of time travel. In Einsteins Masterwork, John Gribbin explains exactly why 1915 was Einsteins greatest year.

John Gribbin, geb. 1946 in Maidstone/Kent, studierte Physik und Astronomie, war Mitarbeiter bei 'Nature', 'New Scientist' und der 'Times'. Er lehrt und forscht an der University of Sussex und hat zahlreiche Sachbücher geschrieben.
