Academic Staff Of The Humboldt University Of Berlin
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Differential Geometers
Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds. It uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra. The field has its origins in the study of spherical geometry as far back as antiquity. It also relates to astronomy, the geodesy of the Earth, and later the study of hyperbolic geometry by Lobachevsky. The simplest examples of smooth spaces are the plane and space curves and surfaces in the three-dimensional Euclidean space, and the study of these shapes formed the basis for development of modern differential geometry during the 18th and 19th centuries. Since the late 19th century, differential geometry has grown into a field concerned more generally with geometric structures on differentiable manifolds. A geometric structure is one which defines some notion of size, distance, shape, volume, or other rigidifying structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century German Mathematicians
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 large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Rothe
Rudolf Ernst Rothe (15 October 1873, Berlin – 26 October 1942, Berlin) was a German applied mathematician. Biography After graduating from the Sophien-Gymnasium in Berlin, Rothe studied from 1892 under Hermann Amandus Schwarz, Johannes Knoblauch, Lazarus Immanuel Fuchs, and Ferdinand Georg Frobenius at the Humboldt University of Berlin.

In 1905 Rothe completed his habilitation at the ''Technische Hochschule Berlin-Charlottenburg'' ( Technical University of Berlin). He was a professor from 1908 to 1914 at the Clausthal University of Technology (TU Claustral) and from 1914 to 1915 at the ''Technische Hochschule Hanover'' ( University of Hanover), where he founded the Institute for Applied Mathematics. From 1915 he was a professor at the Technical University of Berlin, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boroughs And Neighborhoods Of Berlin
Berlin is both a city and one of Germany’s States of Germany, federated states (city state). Since the 2001 administrative reform, it has been made up of twelve districts (german: Bezirke, ), each with its own administrative body. However, unlike the municipalities and counties of other German states, the Berlin districts are not territorial corporations of public law () with autonomous competencies and property, but simple administrative agencies of Berlin's state and city government, the City of Berlin forming a single municipality () since the Greater Berlin Act, Greater Berlin Act of 1920. Thus they cannot be equated to US or UK boroughs in the traditional meaning of the term. Each district possesses a district representatives' assembly () directly elected by proportional representation and an administrative body called district board (). The district board, comprising since October 2021 six (until then five) members - a district mayor () as head and five (earlier four) dist ...

Pankow
Pankow () is the most populous and the second-largest borough by area of Berlin. In Berlin's 2001 administrative reform, it was merged with the former boroughs of Prenzlauer Berg and Weißensee; the resulting borough retained the name Pankow. Pankow was sometimes claimed by the Western Allies (United States, United Kingdom, and France) to be the capital of the German Democratic Republic (East Germany), while the German Democratic Republic itself considered East Berlin to be its capital. Overview The borough, named after the Panke river, covers the northeast of the city region, including the inner city locality of Prenzlauer Berg. It borders Mitte and Reinickendorf in the west, Friedrichshain-Kreuzberg in the south, and Lichtenberg in the east. Pankow is Berlin's largest borough by population and the second largest by area (after Treptow-Köpenick). Between 1945 and 1960, Schönhausen Palace and the nearby Majakowskiring street in the Niederschönhausen locality of Pankow was th ...

Crelle's Journal
''Crelle's Journal'', or just ''Crelle'', is the common name for a mathematics journal, the ''Journal für die reine und angewandte Mathematik'' (in English: ''Journal for Pure and Applied Mathematics''). History The journal was founded by August Leopold Crelle (Berlin) in 1826 and edited by him until his death in 1855. It was one of the first major mathematical journals that was not a proceedings of an academy. It has published many notable papers, including works of Niels Henrik Abel, Georg Cantor, Gotthold Eisenstein, Carl Friedrich Gauss and Otto Hesse. It was edited by Carl Wilhelm Borchardt from 1856 to 1880, during which time it was known as ''Borchardt's Journal''. The current editor-in-chief is Rainer Weissauer (Ruprecht-Karls-Universität Heidelberg) Past editors * 1826–1856 August Leopold Crelle * 1856–1880 Carl Wilhelm Borchardt * 1881–1888 Leopold Kronecker, Karl Weierstrass * 1889–1892 Leopold Kronecker * 1892–1902 Lazarus Fuchs * 1903–1928 Kurt Hens ...

Group Theory
In abstract algebra, group theory studies the algebraic structures known as group (mathematics), groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as ring (mathematics), rings, field (mathematics), fields, and vector spaces, can all be seen as groups endowed with additional operation (mathematics), operations and axioms. Groups recur throughout mathematics, and the methods of group theory have influenced many parts of algebra. Linear algebraic groups and Lie groups are two branches of group theory that have experienced advances and have become subject areas in their own right. Various physical systems, such as crystals and the hydrogen atom, and Standard Model, three of the four known fundamental forces in the universe, may be modelled by symmetry groups. Thus group theory and the closely related representation theory have many important applications in physics, chemistry, and materials science. Group theory is also ce ...
