Friedrich Simon Archenhold
Friedrich Simon Archenhold (2 October 1861 in Lichtenau, Westphalia – 14 October 1939 in Berlin) was an astronomer who founded the Treptow Observatory (today the Archenhold Observatory) in Berlin-Treptow. He graduated from the Realgymnasium in Lippstadt before entering Friedrich Wilhelm University in 1882, where he and Wilhelm Förster founded the Urania Society at the Berlin University Observatory. Largest telescope On the basis of Archenhold's plans, the world's longest moving refracting telescope was built with a focal length of 21 meters. The telescope was part of the Great Industrial Exposition of Berlin, a world's fair. The giant telescope was constructed in Treptow, a suburb of Berlin. The telescope was opened to the public on 1 May 1896 in a temporary wooden structure which was completed in September. Public observatory By 1908 Archenhold had raised the funds to replace the wooden structure with the building that stands today. Some of the funds came from a ...

Berlin Treptow Archenhold Sternwarte
Berlin is the capital and largest city of Germany, both by area and by population. Its more than 3.85 million inhabitants make it the European Union's most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan region after the Rhine-Ruhr region, and the fifth-biggest metropolitan region by GDP in the European Union. Berlin was built along the banks of the Spree river, which flows into the Havel in the western bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century German Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berlin Wall
The Berlin Wall (german: Berliner Mauer, ) was a guarded concrete barrier that encircled West Berlin from 1961 to 1989, separating it from East Berlin and East Germany (GDR). Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961. It included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in the GDR. The authorities officially referred to the Berlin Wall as the ''Anti-Fascist Protection Rampart'' (german: Antifaschistischer Schutzwall, ). The West Berlin city government sometimes referred to it as the " Wall of Shame", a term coined by mayor Willy Brandt in reference to the Wall's restriction on freedom of movement.

Theresienstadt
Theresienstadt Ghetto was established by the SS during World War II in the fortress town of Terezín, in the Protectorate of Bohemia and Moravia ( German-occupied Czechoslovakia). Theresienstadt served as a waystation to the extermination camps. Its conditions were deliberately engineered to hasten the death of its prisoners, and the ghetto also served a propaganda role. Unlike other ghettos, the exploitation of forced labor was not economically significant. The ghetto was established by the transportation of Czech Jews in November 1941. The first German and Austrian Jews arrived in June 1942; Dutch and Danish Jews came at the beginning in 1943, and prisoners of a wide variety of nationalities were sent to Theresienstadt in the last months of the war. About 33,000 people died at Theresienstadt, mostly from malnutrition and disease. More than 88,000 people were held there for months or years before being deported to extermination camps and other killing sites; the Jewish Counci ...

Theory Of Relativity
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including 4-dimensional spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astro ...
