Gottfried Heinsius
Gottfried Heinsius (April, 1709 – May 21, 1769) was a German mathematician, geographer and astronomer. He was born near Naumburg and was awarded a Ph.D. in 1733 from the University of Leipzig with a dissertation on ''De viribus motricibus''. Later he became professor of mathematics at the same institution. Professor Heinsius may have been the first to publish an announcement about the return of Halley's comet in 1759. From 1736–43 he taught in St. Petersburg with Leonhard Euler and was a member of the St. Petersburg Academy of Sciences. While in Russia, he was given the task to provide the Russian Tsar Ivan VI with a horoscope. He died in Leipzig. The crater Heinsius on the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of ... is named after him.

Naumburg
Naumburg () is a town in (and the administrative capital of) the district Burgenlandkreis, in the state of Saxony-Anhalt, Central Germany. It has a population of around 33,000. The Naumburg Cathedral became a UNESCO World Heritage Site in 2018. This UNESCO designation recognizes the processes that shaped the European continent during the High Middle Ages between 1000 and 1300: Christianization, the so-called "Landesausbau" and the dynamics of cultural exchange and transfer characteristic for this very period. History The first written record of Naumburg dates from 1012, when it was mentioned as the ''new castle'' of the Ekkehardinger, the Margrave of Meissen. It was founded at the crossing of two trade-routes, Via Regia and the Regensburg Road. The successful foundation not long beforehand of a ''Propstei'' Church on the site of the later Naumburg Cathedral was mentioned in the Merseburg Bishops' Chronicles in 1021. In 1028 Pope John XIX gave his approval for the transfer of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Leipzig
Leipzig University (german: Universität Leipzig), in Leipzig in Saxony, Germany, is one of the world's oldest universities and the second-oldest university (by consecutive years of existence) in Germany. The university was founded on 2 December 1409 by Frederick I, Elector of Saxony and his brother William II, Margrave of Meissen, and originally comprised the four scholastic faculties. Since its inception, the university has engaged in teaching and research for over 600 years without interruption. Famous alumni include Gottfried Wilhelm von Leibniz, Johann Wolfgang von Goethe, Leopold von Ranke, Friedrich Nietzsche, Robert Schumann, Richard Wagner, Tycho Brahe, Georgius Agricola, Angela Merkel and ten Nobel laureates associated with the university. History Founding and development until 1900 The university was modelled on the University of Prague, from which the German-speaking faculty members withdrew to Leipzig after the Jan Hus crisis and the Decree of Ku ...

Halley's Comet
Halley's Comet or Comet Halley, officially designated 1P/Halley, is a List of periodic comets, short-period comet visible from Earth every 75–79 years. Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and thus the only naked-eye comet that can appear twice in a human lifetime. Halley last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC. But it was not until 1705 that the English astronomer Edmond Halley understood that these appearances were reappearances of the same comet. As a result of this discovery, the comet is named after Halley. During its 1986 visit to the inner Solar System, Halley's Comet became the first comet to be observed in detail by spacecraft, providing the first observational data on the structure of a comet nucleus and the mecha ...

Leonhard Euler
Leonhard Euler ( , ; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He introduced much of modern mathematical terminology and Mathematical notation, notation, including the notion of a function (mathematics), mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss remarked: "The study of Euler's works will remain the best school for the different fields of mathematics, a ...

Tsar
Tsar ( or ), also spelled ''czar'', ''tzar'', or ''csar'', is a title used by East and South Slavic monarchs. The term is derived from the Latin word ''caesar'', which was intended to mean "emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to "king". It lends its name to a system of government, tsarist autocracy or tsarism. "Tsar" and its variants were the official titles of the following states: * Bulgarian Empire ( First Bulgarian Empire in 681–1018, Second Bulgarian Empire in 1185–1396), and also used in Tsardom of Bulgaria, in 1908–1946 * Serbian Empire, in 1346–1371 * Tsardom of Russia, in 1547–1721 (replaced in 1721 by '' imperator'' in Russian Empire, but still remaining in use, also officially in relation to sever ...

Ivan VI Of Russia
Ivan VI,; – (Julian calendar should be used in this article) Iván or Ioánn Antónovich (12 August 1740 5 July 1764) was an infant emperor of Russia who was overthrown by his cousin Elizabeth Petrovna in 1741. He was only two months old when he was proclaimed emperor and his mother named regent, but the throne was seized in the coup after a year. Ivan and his parents were imprisoned far from the capital, and spent the rest of their lives in captivity. After more than twenty years as a prisoner, Ivan was killed by his guards when some army officers (unknown to Ivan) attempted to free him. His surviving siblings, who had been born in prison, were then released into the custody of their aunt, the Danish queen dowager Juliana Maria of Brunswick-Wolfenbüttel. They settled in Horsens, where they lived in comfort under house arrest for the rest of their lives. Emperor of Russia Ivan was born on 23 August 1740 at Saint Petersburg, the eldest child of Duke Anthony Ulrich of Bru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leipzig
Leipzig ( , ; Upper Saxon: ) is the most populous city in the German state of Saxony. Leipzig's population of 605,407 inhabitants (1.1 million in the larger urban zone) as of 2021 places the city as Germany's eighth most populous, as well as the second most populous city in the area of the former East Germany after ( East) Berlin.

Heinsius (crater)
Heinsius is an eroded lunar impact crater that lies in the southwestern part of the Moon. It is named after German astronomer Gottfried Heinsius. It is located to the northwest of the prominent crater Tycho, and rays from that formation pass to the north and south of Heinsius as well as marking the rim and interior with material. To the south-southwest of Heinsius is the larger walled plain Wilhelm. The southern part of this crater has been heavily damaged by subsequent impacts. Both Heinsius B and Heinsius C lie across the southern and southwestern rim, while Heinsius A is located in the southern interior floor. Together these three satellite craters form a triangular arrangement with the rims only separated by a few kilometers from each other. If Heinsius possessed a central peak, it is now covered by the outer rampart Rampart may refer to: * Rampart (fortification), a defensive wall or bank around a castle, fort or settlement Rampart may also refer to: * "O'er the Rampa ...
