Ernst Christian Julius Schering
Ernst Christian Julius Schering (13 July 1833 – 2 November 1897) was a German mathematician. Early life and career Born in 1833 near Bleckede at the Elbe as the son of a forester, he attended Realschule ("Johanneum") in Lüneburg from 1845 to 1850, where he already showed a certain talent for mathematics. With the intention to engage in architectural engineering, he attended the Polytechnicum in Hannover from 1850 to 1852. At the University of Göttingen Following a fondness of mathematics and physics, in 1852, at the age of 19, he moved on to study in Göttingen, attending classes by Gauß, Weber, Dirichlet, Stern and Riemann. In 1857, he received a doctoral degree for his award-winning manuscript "Zur mathematischen Theorie electrischer Ströme" ("On the mathematical theory of electric currents"). In 1858, he habilitated based on his work "Über die conforme Abbildung des Ellipsoids auf der Ebene" ("On the conformal mapping of the ellipsoid on the plane"). After turn ...

Bleckede
Bleckede (, Polabian ''Bleketsa'') is a town in the district of Lüneburg, in Lower Saxony, Germany. It is situated mostly on the left bank of the Elbe, approx. 20 km east of Lüneburg. Bleckede is located on the German Timber-Frame Road. History In the course of the eastern colonisation the area of today's Bleckede became a part of the Duchy of Saxony. The current name derives from an older variant Bleketsa, a Slavic term. After the Welf Saxon, Duke Henry the Lion, had been overthrown and deposed in 1180, the Welfs lost most of Saxony, including the ducal title which was granted to the House of Ascania. The Ascanians also claimed Bleckede. However, Henry's son William of Winchester disputed that claim and made Bleckede the Welf outpost upon Elbe in 1209, in order to have a step towards the trans-Elbian areas which were in the process of colonisation by settlers from the west. William also levied a toll from ships passing Bleckede and renamed the city in honour of his f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Göttingen Observatory
Göttingen Observatory (''Universitätssternwarte Göttingen'' (Göttingen University Observatory) or ''königliche Sternwarte Göttingen'' (Royal Observatory Göttingen)) is a German astronomical observatory located in Göttingen, Lower Saxony, Germany. History In 1802, George III of the United Kingdom, who was also the prince-elector of Hanover, allocated 22,680 thalers for a new observatory. The plans were developed, like many of the university's buildings, by Georg Heinrich Borheck. Construction was delayed by the French Revolutionary Wars and extended from 1803 until 1816. At the time, the building was on the outskirts of Göttingen, to ensure an unobstructed view of the night sky. Carl Friedrich Gauss became the first director of the Observatory, and lived there between 1815 and 1855. Gauss arranged for the installation of two meridian circles (produced by Johann Georg Repsold and Georg Friedrich von Reichenbach in 1818 and 1819. Gauss was succeeded by Wilhelm Weber and ...

Göttingen Academy Of Sciences And Humanities
The Göttingen Academy of Sciences (german: Akademie der Wissenschaften zu Göttingen)Note that the German ''Wissenschaft'' has a wider meaning than the English "Science", and includes Social sciences and Humanities. is the second oldest of the seven academies of sciences in Germany. It has the task of promoting research under its own auspices and in collaboration with academics in and outside Germany. It has its seat in the university town of Göttingen. History The '' Königliche Gesellschaft der Wissenschaften'' ("Royal Society of Sciences") was founded in 1751 by King George II of Great Britain, who was also Prince-Elector of the Holy Roman Empire and Duke of Brunswick-Lüneburg (Hanover), the German state in which Göttingen was located. The first president was the Swiss natural historian and poet Albrecht von Haller. It was renamed the "Akademie der Wissenschaften zu Göttingen" in 1939. Among the learned societies in the Federal Republic of Germany, the Göttingen academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gießen
Giessen, spelled Gießen in German (), is a town in the German state (''Bundesland'') of Hesse, capital of both the district of Giessen and the administrative region of Giessen. The population is approximately 90,000, with roughly 37,000 university students. The name comes from ''Giezzen'', as it was first referred to in 1197, which refers to the position of the town between several rivers, lakes and streams. The largest river in Giessen is the Lahn, which divides the town in two parts (west and east), roughly north of Frankfurt am Main. Giessen is also home to the University of Giessen. In 1969, the town hosted the ninth '' Hessentag'' state festival. History Giessen came into being as a moated castle in 1152 built by Count Wilhelm von Gleiberg, although the history of the community in the northeast and in today's suburb called "Wieseck" dates back to 775. The town became part of Hesse-Marburg in 1567, passing to Hesse-Darmstadt in 1604. The University of Giessen was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a dissertation. The degree, abbreviated "Dr. habil." (Doctor habilitatus) or "PD" (for "Privatdozent"), is a qualification for professorship in those countries. The conferral is usually accompanied by a lecture to a colloquium as well as a public inaugural lecture. History and etymology The term ''habilitation'' is derived from the Medieval Latin , meaning "to make suitable, to fit", from Classical Latin "fit, proper, skillful". The degree developed in Germany in the seventeenth century (). Initially, habilitation was synonymous with "doctoral qualification". The term became synonymous with "post-doctoral qualification" in Germany in the 19th century "when holding a doctorate seemed no longer sufficient to guarantee a proficient transfe ...

Doctoral Degree
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism '' licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals ...

Bernhard Riemann
Georg Friedrich Bernhard Riemann (; 17 September 1826 – 20 July 1866) was a German mathematician who made contributions to analysis, number theory, and differential geometry. In the field of real analysis, he is mostly known for the first rigorous formulation of the integral, the Riemann integral, and his work on Fourier series. His contributions to complex analysis include most notably the introduction of Riemann surfaces, breaking new ground in a natural, geometric treatment of complex analysis. His 1859 paper on the prime-counting function, containing the original statement of the Riemann hypothesis, is regarded as a foundational paper of analytic number theory. Through his pioneering contributions to differential geometry, Riemann laid the foundations of the mathematics of general relativity. He is considered by many to be one of the greatest mathematicians of all time. Biography Early years Riemann was born on 17 September 1826 in Breselenz, a village near D ...

Moritz Abraham Stern
Moritz Abraham Stern (29 June 1807 – 30 January 1894) was a German mathematician. Stern became ''Ordinarius'' (full professor) at Göttingen University in 1858, succeeding Carl Friedrich Gauss. Stern was the first Jewish full professor at a German university who attained the position without changing his Jewish religion. Although Carl Gustav Jacobi preceded him (by three decades) as the first Jew to obtain a math professorial chair in Germany, Jacobi's family had converted to Christianity long before then. As a professor, Stern taught Gauss's student Bernhard Riemann. Stern was very helpful to Gotthold Eisenstein in formulating a proof of the quadratic reciprocity theorem. Stern was interested in primes that cannot be expressed as the sum of a prime and twice a square (now known as Stern prime A Stern prime, named for Moritz Abraham Stern, is a prime number that is not the sum of a smaller prime and twice the square of a non zero integer. That is, if for a prime ''q'' th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Gustav Lejeune Dirichlet
Johann Peter Gustav Lejeune Dirichlet (; 13 February 1805 – 5 May 1859) was a German mathematician who made deep contributions to number theory (including creating the field of analytic number theory), and to the theory of Fourier series and other topics in mathematical analysis; he is credited with being one of the first mathematicians to give the modern formal definition of a function. Although his surname is Lejeune Dirichlet, he is commonly referred to by his mononym Dirichlet, in particular for results named after him. Biography Early life (1805–1822) Gustav Lejeune Dirichlet was born on 13 February 1805 in Düren, a town on the left bank of the Rhine which at the time was part of the First French Empire, reverting to Prussia after the Congress of Vienna in 1815. His father Johann Arnold Lejeune Dirichlet was the postmaster, merchant, and city councilor. His paternal grandfather had come to Düren from Richelette (or more likely Richelle), a small community north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Eduard Weber
Wilhelm Eduard Weber (; ; 24 October 1804 – 23 June 1891) was a German physicist and, together with Carl Friedrich Gauss, inventor of the first electromagnetic telegraph. Biography of Wilhelm Early years Weber was born in Schlossstrasse in Wittenberg, where his father, Michael Weber, was professor of theology. The building had previously been the home of Abraham Vater. Wilhelm was the second of three brothers, all of whom were distinguished by an aptitude for science. After the dissolution of the University of Wittenberg his father was transferred to Halle in 1815. Wilhelm had received his first lessons from his father, but was now sent to the Orphan Asylum and Grammar School at Halle. After that he entered the University, and devoted himself to natural philosophy. He distinguished himself so much in his classes, and by original work, that after taking his degree of Doctor and becoming a '' Privatdozent'' he was appointed Professor Extraordinary of natural philosophy at ...
