Einsteinturm
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 ''Prussian semaphore system#Route, 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 Astrophysical Institute Potsdam, 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 telescop ...

Erich Mendelsohn
Erich Mendelsohn (21 March 1887 – 15 September 1953) was a German architect, known for his expressionist architecture in the 1920s, as well as for developing a dynamic Functionalism (architecture), functionalism in his projects for department stores and cinemas. Mendelsohn was a pioneer of the Art Deco and Streamline Moderne architecture, notably with his 1921 Mossehaus design. Biography Mendelsohn was born to a Jewish family in Olsztyn, Allenstein, East Prussia, Germany, now the Polish town of Olsztyn. His birthplace was at the former Oberstrasse 21, now no. 10 Staromiejska street. A plaque embedded on the wall on the side of Barbara street commemorates his place of birth. He was not related to the Mendelssohn family. He was the fifth of six children; his mother was Emma Esther (née Jaruslawsky), a hatmaker and his father David was a shopkeeper. He attended a humanist ''Gymnasium (school), Gymnasium'' in Allenstein and continued with commercial training in Berlin. In 1906 ...

Erwin Finlay-Freundlich
Erwin Finlay-Freundlich FRSE FRAS (; 29 May 1885 – 24 July 1964) was a German astronomer, a pupil of Felix Klein. Freundlich was a working associate of Albert Einstein and introduced experiments for which the general theory of relativity could be tested by astronomical observations based on the gravitational redshift. Life He was born in Biebrich, Germany the son of Friedrich Philipp Ernst Freundlich, a manufacturer, and his wife Elizabeth (Ellie) Finlayson. He was one of seven children, all of whom were raised Protestant, despite their father's Jewish heritage. His elder brother was Herbert Max Finlay Freundlich. He studied locally, leaving school in 1903. He spent 6 months working in the shipyards of Stettin which inspired him to begin studying shipbuilding at the Charlottenburg Polytechnic in Berlin. However he abandoned this in autumn 1905 to instead study Mathematics and Astronomy at Göttingen. Here he studied under Felix Klein and Karl Schwarzschild. In 1913 he ...

List Of Solar Telescopes
This is a list of solar telescopes built in various countries around the world. A solar telescope is a specialized telescope that is used to observe the Sun. This list contains ground-based professional observatory telescopes at optical wavelengths in chronological order. Solar telescopes often have multiple focal lengths, and use a various combination of mirrors such as coelostats, lenses, and tubes for instruments including spectrographs, cameras, or coronagraphs. There are many types of instruments that have been designed to observe Earth's Sun, for example, in the 20th century solar towers were common. Ground telescopes Optical telescopes Telescopes for the Sun have existed for hundreds of years, this list is not complete and only goes back to 1900. Potential future optical telescopes Radio telescopes Other types of solar telescopes There are much smaller commercial and/or amateur telescopes such as ''Coronado Filters'' from founder and designer David Lunt, bought by Me ...

Expressionist Architecture
Expressionist architecture was an architectural movement in Europe during the first decades of the 20th century in parallel with the expressionist visual and performing arts that especially developed and dominated in Germany. Brick Expressionism is a special variant of this movement in western and northern Germany, as well as in the Netherlands (where it is known as the Amsterdam School). In the 1920s The term "Expressionist architecture" initially described the activity of the German, Dutch, Austrian, Czech and Danish avant garde from 1910 until 1930. Subsequent redefinitions extended the term backwards to 1905 and also widened it to encompass the rest of Europe. Today the meaning has broadened even further to refer to architecture of any date or location that exhibits some of the qualities of the original movement such as; distortion, fragmentation or the communication of violent or overstressed emotion. The style was characterised by an early-modernist adoption of novel ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potsdam
Potsdam () is the capital and, with around 183,000 inhabitants, largest city of the German state of Brandenburg. It is part of the Berlin/Brandenburg Metropolitan Region. Potsdam sits on the River Havel, a tributary of the Elbe, downstream of Berlin, and lies embedded in a hilly morainic landscape dotted with many lakes, around 20 of which are located within Potsdam's city limits. It lies some southwest of Berlin's city centre. The name of the city and of many of its boroughs are of Slavic origin. Potsdam was a residence of the Prussian kings and the German Kaiser until 1918. Its planning embodied ideas of the Age of Enlightenment: through a careful balance of architecture and landscape, Potsdam was intended as "a picturesque, pastoral dream" which would remind its residents of their relationship with nature and reason. The city, which is over 1000 years old, is widely known for its palaces, its lakes, and its overall historical and cultural significance. Landmarks include ...

Coelostat
A solar telescope is a special purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far outside, the visible spectrum. Obsolete names for Sun telescopes include heliograph and photoheliograph. Professional solar telescopes Solar telescopes need optics large enough to achieve the best possible diffraction limit but less so for the associated light-collecting power of other astronomical telescopes. However, recently newer narrower filters and higher framerates have also driven solar telescopes towards photon-starved operations. Both the Daniel K. Inouye Solar Telescope as well as the proposed European Solar Telescope (EST) have larger apertures not only to increase the resolution, but also to increase the light-collecting power. Because solar telescopes operate during the day, seeing is generally worse than for night-time telescopes, because the ground around the telescope is heated which causes turbulence and degrades the res ...

Astrophysical Institute Potsdam
Leibniz Institute for Astrophysics Potsdam (AIP) is a German research institute. It is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory Potsdam (AOP) founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP was founded in 1992, in a re-structuring following the German reunification. The AIP is privately funded and member of the Leibniz Association. It is located in Babelsberg in the state of Brandenburg, just west of Berlin, though the Einstein Tower solar observatory and the great refractor telescopeGreat Refractor telescope at Telegrafenberg on Telegrafenberg i ...

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 during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
