Biography Eddington, Arthur Stanley
English physicist and astronomer Arthur Stanley Eddington (Arthur Stanley Eddington) (1882-1944) was born in the small town of Kendal in the north of England. He studied at Cambridge University, and from 1906 to 1913. was an assistant of the oldest in England Greenwich Observatory. Since 1913. Eddington - Professor and Director of the Observatory of the University Kemridzhskogo.
Eddington's first work as an astronomer associated with the study of movements of stars and the structure of stellar systems. But his main achievement - the fact that he created the theory of internal structure of stars. Penetrate deep into the physical essence of phenomena and finesse techniques complex mathematical calculations allowed Eddington to obtain some fundamental results in the areas of astrophysics, . as the internal structure of stars, . state of interstellar matter, . movement and distribution of stars in the galaxy,
Eddington calculated the diameters of some of the red giant stars, determined the density of a dwarf companion star Sirius - it was unusually high. Work Eddington, by definition, the density of stars, have led to the development of physics of superdense (degenerate) of gas.
Eddington was a good interpreter of the general theory of relativity Einstein. He implemented the first experimental verification of one of the effects predicted by this theory: the deviation of light rays in the gravitational field of a massive star. That he managed to do during a total eclipse of the Sun in 1919.
Together with other scientists Eddington laid the foundations of modern knowledge about the structure of stars.
