The theory of relativity is actually a conglomerate of two theories which Einstein theorized at different times. Special relativity was published in 1905 and changed the scientific world until some of the ideas could not hold up to scrutiny. It was then that Einstein published the theory of general relativity in 1916.
Albert Einstein is not credited with creating any inventions. He did create many different theories in the field of physics. He wrote the theory of special relativity and the general theory of relativity.
The scientific Theories of General and Special Relativity were first proposed by Albert Einstein.Special Relativity in 1906 and General Relativity in 1916.
Einstein wasn't really an inventor he was a theoretical physicist. Some of his greatest discoveries were general relativity, the quantisation of the photon and the mass energy equivalence equation (E=MC^2).
General Relativity - book - was created in 1984.
E=mc^2 Edit : That equation is part of "special relativity" not "general relativity".
As well as the oft repeated E=MC2, Einstein also produced advances in the photoelectric effect (for which he received the Nobel prize), Brownian motion, and in relativity both special and general. He was also quite active in cosmology, and predicted gravitational lensing. (Bending of light as it passes a star). He also had theories on special and general relativity.
General Relativity - book - has 491 pages.
One special event that was a highlight in Albert Einsteins' life was when a solar eclipse let British astronomers confirm the general theory of relativity.
