Friedrich Dingeldey
Friedrich Dingeldey (16 December 1859, Darmstadt – 24 September 1939, Darmstadt) was a German mathematician. Education and career After secondary education at Ludwig Georgs Gymnasium in Darmstadt, Dingeldey studied at the universities of Giessen, Leipzig and Munich. From 1886 to 1892 he worked as a teacher in Darmstadt and Groß-Gerau. In 1885 Dingeldey received his PhD (Promotierung), with primary supervisor Felix Klein and co-supervisor Carl Neumann, from the University of Leipzig with thesis ''Über die Erzeugung von Curven vierter Ordnung durch Bewegungsmechanismen''. In 1889 he completed his habilitation at the TH Darmstadt with a habilitation thesis on knot theory entitled ''Über einen neuen topologischen Process und die Entstehungsbedingungen einfacher Verbindungen und Knoten in gewissen geschlossenen Flächen''. His research followed the work of the Viennese mathematician Oskar Simony. (In 1890 Dingeldey had a pamphlet published with a brief history of topology and b ...

Heads Of Universities In Germany
A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissue concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head. Human head The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). Sculptures of human heads are generally based on a ske ...

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] |
International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

Wilhelm Fiedler
Otto Wilhelm Fiedler (3 April 1832 in Chemnitz – 19 November 1912 in Zurich) was a German-Swiss mathematician, known for his textbooks of geometry and his contributions to descriptive geometry. Life Fiedler was the son of a shoemaker. He went to the Royal Mercantile College in Chemnitz and in 1849 to the Bergakademie Freiberg as an external student. In 1852 he became a mathematics teacher at the "Werkmeisterschule" in Freiberg and 1853 at the "Gewerbeschule" in Chemnitz. He had to take care of his widowed mother and his siblings, and educated himself without directly attending a university. In 1858 he obtained the doctorate in mathematics at the University of Leipzig under August Ferdinand Möbius (''Die Zentralprojektion als geometrische Wissenschaft''). Fiedler made himself known by editing the translation of the textbooks of analytic, projective, and algebraic geometry by George Salmon (in the 19th century known in Germany as "Salmon-Fiedler"). He was a friend of Salm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Salmon
George Salmon FBA FRS FRSE (25 September 1819 – 22 January 1904) was a distinguished and influential Irish mathematician and Anglican theologian. After working in algebraic geometry for two decades, Salmon devoted the last forty years of his life to theology. His entire career was spent at Trinity College Dublin. Personal life Salmon was born in Dublin, to Michael Salmon and Helen Weekes (the daughter of the Reverend Edward Weekes), but he spent his boyhood in Cork City, where his father Michael was a linen merchant.

Deutsche Akademie Der Naturforscher Leopoldina
The German National Academy of Sciences Leopoldina (german: Deutsche Akademie der Naturforscher Leopoldina – Nationale Akademie der Wissenschaften), short Leopoldina, is the national academy of Germany, and is located in Halle (Saale). Founded on January 1, 1652, based on academic models in Italy, it was originally named the ''Academia Naturae Curiosorum'' until 1687 when Emperor Leopold I raised it to an academy and named it after himself. It was since known under the German name ''Deutsche Akademie der Naturforscher Leopoldina'' until 2007, when it was declared to be Germany's National Academy of Sciences. History ' The Leopoldina was founded in the imperial city of Schweinfurt on 1 January 1652 under the Latin name sometimes translated into English as "Academy of the Curious as to Nature." It was founded by four local physicians- Johann Laurentius Bausch, the first president of the society, Johann Michael Fehr, Georg Balthasar Metzger, and Georg Balthasar Wohlfarth; and w ...
