Dietrich Mahnke
Dietrich Mahnke (17 October 1884, Verden – 25 July 1939, Fürth) was a German philosopher and historian of mathematics. From 1902–1906, Mahnke studied at Göttingen under Edmund Husserl and David Hilbert. After serving in the First World War (stationed in Lens, France), he graduated from the University of Freiburg in 1925 with a thesis on Leibniz. The thesis was later published in the Jahrbuch für Philosophie und phänomenologische Forschung as ''Leibnizens Synthese von Universalmathematik und Individualmetaphysik''. In 1926 he habilitated at Greifswald with a thesis entitled ''Neue Einblicke in die Entdeckungsgeschichte der höheren Analysis''. In 1927 he became a professor of philosophy at Marburg. In 1934 he became a member of the Nazi SA. Mahnke's work in the history of mathematics focussed primarily on Leibniz's development of the infinitesimal calculus, and his relationship to Neo-Platonism. His last book, ''Unendliche Sphäre und Allmittelpunkt, Beiträge zu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verden An Der Aller
Verden an der Aller (; Northern Low Saxon: ''Veern''), also called Verden (Aller) or simply Verden, is a town in Lower Saxony, Germany, on the river Aller. It is the district town of the district of Verden in Lower Saxony and an independent municipality ( :de:Selbständige Gemeinde). The town is located in the middle Weser region on the Aller river immediately before it flows into the Weser. As a center of horse breeding and equestrian sports, it bears the nickname "equestrian town". The suffix "Aller" was introduced at a time when the name "Verden" was also common for the French town of Verdun in the German-speaking area. The town name comes from "ford" or "ferry". The town was conveniently located at a ford through the Aller river, near an important trade route. Verden is famous for a massacre of Saxons in 782, committed on the orders of Charlemagne (the Massacre of Verden), for its cathedral, and for its horse-breeding. History In the Early Middle Ages (year 782) there was a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infinitesimal Calculus
Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations. It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while the latter concerns accumulation of quantities, and areas under or between curves. These two branches are related to each other by the fundamental theorem of calculus, and they make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. Infinitesimal calculus was developed independently in the late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz. Later work, including codifying the idea of limits, put these developments on a more solid conceptual footing. Today, calculus has widespread uses in scien ...

Academic Staff Of The University Of Marburg
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, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturmabteilung Personnel
The (; SA; literally "Storm Detachment") was the original paramilitary wing of the Nazi Party. It played a significant role in Adolf Hitler's rise to power in the 1920s and 1930s. Its primary purposes were providing protection for Nazi rallies and assemblies, disrupting the meetings of opposing parties, fighting against the paramilitary units of the opposing parties, especially the ''Roter Frontkämpferbund'' of the Communist Party of Germany (KPD) and the ''Reichsbanner Schwarz-Rot-Gold'' of the Social Democratic Party of Germany (SPD), and intimidating Romani, trade unionists, and especially Jews. The SA were colloquially called Brownshirts () because of the colour of their uniform's shirts, similar to Benito Mussolini's blackshirts. The official uniform of the SA was the brown shirt with a brown tie. The color came about because a large shipment of Lettow-shirts, originally intended for the German colonial troops in Germany's former East Africa colony, was purchased in ...

Joseph W
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled '' Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and k ...

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between brack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
