Yerkes Observatory (/ ˈ j ɜːr k iː z / ⓘ YUR-keez) is an astronomical observatory located in Williams Bay, Wisconsin, United States. The observatory was operated by the University of Chicago Department of Astronomy and Astrophysics [ 2 ] [ 3 ] from its founding in 1897 until 2018.
Tests of general relativity serve to establish observational evidence for the theory of general relativity.The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
Yerkes Observatory: Walter Sydney Adams (December 20, 1876 ... this was regarded as significant confirmation of Albert Einstein's theory of General Relativity. It is ...
The Astrophysical Journal was previously published at the observatory and the facility was the site of the first meeting of the American Astronomical Society in 1899. Albert Einstein visited the observatory during his first trip to the United States in 1921. The facility is operated by the Yerkes Future Foundation.
The 40-inch (1.02 m) refractor telescope backdrops Albert Einstein's visit to the Yerkes Observatory in May 1921. The 40-inch refractor telescope was modernized in the late 1960s with electronics of the period.
He arrived at Denison University in 1911 where he was the professor and lecturer of astronomy and the director of the Warner and Swasey Observatory. He continued to teach at Denison University and lived in Granville, Ohio until his death in June 1943. Biefeld joined the Yerkes Eclipse Expedition to Denver, Colorado in 1918.
George Ellery Hale (June 29, 1868 – February 21, 1938) was an American astrophysicist, best known for his discovery of magnetic fields in sunspots, and as the leader or key figure in the planning or construction of several world-leading telescopes; namely, the 40-inch refracting telescope at Yerkes Observatory, 60-inch Hale reflecting telescope at Mount Wilson Observatory, 100-inch Hooker ...
Albert Einstein together with Marcel Grossmann starts to develop a theory which would bind metric tensor g ik, which defines a space geometry, with a source of gravity, that is with mass. Hans Geiger and Ernest Marsden discover large angle deflections of alpha particles by thin metal foils.
