Einsteinturm 7443
The Einstein Tower (German: ''Einsteinturm'') is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany built by architect Erich Mendelsohn. It was built on the summit of the Potsdam '' Telegraphenberg'' to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate (or disprove) Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam. Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory. This was one of Mendelsohn's first major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Wilson Observatory
The Mount Wilson Observatory (MWO) is an astronomical observatory in Los Angeles County, California, United States. The MWO is located on Mount Wilson, a peak in the San Gabriel Mountains near Pasadena, northeast of Los Angeles. The observatory contains two historically important telescopes: the Hooker telescope, which was the largest aperture telescope in the world from its completion in 1917 to 1949, and the 60-inch telescope which was the largest operational telescope in the world when it was completed in 1908. It also contains the Snow solar telescope completed in 1905, the 60 foot (18 m) solar tower completed in 1908, the 150 foot (46 m) solar tower completed in 1912, and the CHARA array, built by Georgia State University, which became fully operational in 2004 and was the largest optical interferometer in the world at its completion. Due to the inversion layer that traps warm air and smog over Los Angeles, Mount Wilson has steadier air than any other location in ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICOMOS
The International Council on Monuments and Sites (ICOMOS; french: links=no, Conseil international des monuments et des sites) is a professional association that works for the conservation and protection of cultural heritage places around the world. Now headquartered in Charenton-le-Pont, France, ICOMOS was founded in 1965 in Warsaw as a result of the Venice Charter of 1964, and offers advice to UNESCO on World Heritage Sites. The idea behind ICOMOS dates to the Athens Conference on the restoration of historic buildings in 1931, organized by the International Museums Office. The Athens Charter of 1931 introduced the concept of international heritage. In 1964, the Second Congress of Architects and Specialists of Historic Buildings, meeting in Venice, adopted 13 resolutions. The first created the International Charter on the Conservation and Restoration of Monuments and Sites, better known as Venice Charter; the second, put forward by UNESCO, created ICOMOS to carry out this chart ...

Klaus Hentschel
Klaus Hentschel (born 4 April 1961) is a German physicist, historian of science and Professor and head of the History of Science and Technology section in the History Department of the University of Stuttgart. He is known for his contributions in the field of the history of science. Life and work Born in Bad Nauheim, Hentschel from 1979 to 1985 studied physics, philosophy, science, history and musicology at the University of Hamburg. He completed his studies in philosophy in 1985 with the master's examination, and a study in physics in 1987. After some studies in the United States, among others in Boston on a DAAD, he in 1989 received his PhD at the University of Hamburg. His thesis was entitled "Interpretationen und Fehlinterpretationen der speziellen und der allgemeinen Relativitätstheorie durch Zeitgenossen Albert Einsteins" (Interpretations and misinterpretations of the special and general relativity theory by Albert Einstein's contemporaries). After graduation Hentsche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
