Berlin Treptow Archenhold Sternwarte 2
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 boro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Karl Friedrich Zöllner
Johann Karl Friedrich Zöllner (8 November 1834, Berlin25 April 1882, Leipzig) was a German astrophysicist who studied optical illusions. He was also an early psychical investigator. Biography From 1872 he held the chair of astrophysics at Leipzig University. He wrote numerous papers on photometry and spectrum analysis in Poggendorff's '' Annalen'' and ''Berichte der k. sächsischen Gesellschaft der Wissenschaften'', two works on celestial photometry (''Grundzüge einer allgemeinen Photometrie des Himmels'', Berlin, 1861, 4to, and ''Photometrische Untersuchungen'', Leipzig, 1865, 8vo), and a curious book, ''Ueber die Natur der Cometen'' (Leipzig, 1872, 3rd ed. 1883). He discovered the Zöllner illusion where lines that are parallel appear diagonal. He also successfully proved Christian Doppler's theory on the effect of motion of the color of stars, and the resulting shift of absorption lines, via the invention of a very sensitive spectroscope which he named "Reversionspectros ...

Ostwalds Klassiker Der Exakten Wissenschaften
Ostwalds Klassiker der exakten Wissenschaften (English: Ostwald's classics of the exact sciences) is a German book series that contains important original works from all areas of natural sciences. It was founded in 1889 by the physical chemist Wilhelm Ostwald and is now published by Europa-Lehrmittel. History The series was first published by Wilhelm Engelmann in Leipzig and then by Akademische Verlagsgesellschaft in Leipzig and more recently in reprints and new editions by Verlag Harri Deutsch in Frankfurt. Ostwald's aim was to remedy the "" (Lack of knowledge of those great works on which the edifice of science rests). The first volume in 1889 was (On the conservation of power) (first 1847) by Hermann von Helmholtz. In 1894, the physicist Arthur von Oettingen von Ostwald took over the editing (and remained editor until 1920, when Ostwald's son, Wolfgang Ostwald, took over the task). However, Ostwald initially continued to publish the chemistry volumes until he was replaced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Revolutionibus Orbium Coelestium
''De revolutionibus orbium coelestium'' (English translation: ''On the Revolutions of the Heavenly Spheres'') is the seminal work on the heliocentric theory of the astronomer Nicolaus Copernicus (1473–1543) of the Polish Renaissance. The book, first printed in 1543 in Nuremberg, Holy Roman Empire, offered an alternative model of the universe to Ptolemy's geocentric system, which had been widely accepted since ancient times. History Copernicus initially outlined his system in a short, untitled, anonymous manuscript that he distributed to several friends, referred to as the ''Commentariolus''. A physician's library list dating to 1514 includes a manuscript whose description matches the ''Commentariolus'', so Copernicus must have begun work on his new system by that time. Most historians believe that he wrote the ''Commentariolus'' after his return from Italy, possibly only after 1510. At this time, Copernicus anticipated that he could reconcile the motion of the Earth with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christoph Rothmann
Christoph Rothmann (born between 1550 and 1560 in Bernburg, Saxony-Anhalt; died probably after 1600 in Bernburg) was a German mathematician and one of the few well-known astronomers of his time. His research contributed substantially to the fact that Kassel became a European center of the astronomy in the 16th century. Life It is not known today when Rothmann was born, although it is known that his place of birth was Bernberg on the Saale, probably between 1550 and 1560. After a basic education he studied theology and mathematics in Wittenberg with support of the prince, Joachim Ernst von Anhalt. Rothmann's enthusiasm for the astronomy was substantial. Christoph Rothmann was appointed in 1577 as court mathematician in Kassel by Prince Wilhelm IV of Hessen. From 1584 to 1590 he was active in astronomy at the observatory of the prince. His research contributed substantially to the fact that Kassel became a center of the astronomical research. In 1590 he visited Tycho Brahe in Ura ...

Insel Verlag
Suhrkamp Verlag is a German publishing house, established in 1950 and generally acknowledged as one of the leading European publishers of fine literature. Its roots go back to the "arianized" part of the S. Fischer Verlag. In January 2010 the headquarters of the company moved from Frankfurt to Berlin. Suhrkamp declared bankruptcy in 2013, following a longstanding legal conflict between its owners. In 2015, economist Jonathan Landgrebe was announced as director. Early history The firm was established by Peter Suhrkamp, who had led the equally renowned S. Fischer Verlag since 1936. As the censorship of the Nazi Regime endangered the existence of the S. Fischer Verlag with its many dissident authors, Gottfried Bermann Fischer in 1935 reached an agreement with the Propaganda Ministry under which the publication of the not accepted authors would leave Germany while others, the "aryanized" part, would be published under Peter Suhrkamp as managing director and, inter alia, the name " ...

Friedrich Wilhelm Herschel
Frederick William Herschel (; german: Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-born British astronomer and composer. He frequently collaborated with his younger sister and fellow astronomer Caroline Herschel (1750–1848). Born in the Electorate of Hanover, William Herschel followed his father into the military band of Hanover, before emigrating to Great Britain in 1757 at the age of nineteen. Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). The resolving power of the Herschel telescopes revealed that many objects called nebulae in the Messier catalogue were actually clusters of stars. On 13 March 1781 while making observations he made note of a new object in the constellation of Gemini. This would, after several weeks of verification and consultat ...

Diedrich Wattenberg
Diedrich Wattenberg (13 June 1909 – 26 November 1996) was a German astronomer. He was a prolific populariser, writer and speaker on his subject, becoming in the 1950s a familiar presence on radio and, later, television programmes. Life Wattenburg was born in a downstream suburb of Bremen during the first decade of the twentieth century. His father was a coppersmith. For economic reasons there was no possibility of his attending a secondary school, and he therefore trained for work as a government official. A decisive experience came in 1924 when Wattenburg attended a presentation by the writer Bruno H. Bürgel who was reading extracts from his autobiography: Bürgel's autobiography was entitled "Von Arbeiter zum Astronomen" (''"From workers to astronomers"''). Then in 1928, he got to know Friedrich Simon Archenhold at the Treptow Observatory (as it was then called) in Berlin. Wattenburg quickly became one of the regular contributors to a journal called "Das Weltall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...
