Karl Christian Von Langsdorf
Karl Christian von Langsdorf, also known as Carl Christian von Langsdorff (18 May 1757 in Bad Nauheim, Nauheim – 10 June 1834 in Heidelberg), was a German mathematician, geologist, natural scientist and engineer. Life Langsdorf was the son of Georg Melchior Langsdorff and Maria Margarethe Koch. His father was saltworks archivist and Hesse-Hanau ''Rentmeister'' (master of the bursary) (saltworks of Nauheim). He had a twin brother named Daniel Isaak. After finishing ''Gymnasium (school), Gymnasium'' (secondary school) in Idstein in 1773, Langsdorf studied, among other things, philosophy, law, and mathematics at University of Göttingen from 1774 until autumn of 1776 with Abraham Gotthelf Kästner and then until 1777 at the University of Giessen. He then interned at the saltworks in Salzhausen, and subsequently devoted himself in Nidda, Hesse to the study of saltworks. He finished his doctorate in 1781 in Erfurt.

Erfurt
Erfurt () is the capital and largest city in the Central German state of Thuringia. It is located in the wide valley of the Gera river (progression: ), in the southern part of the Thuringian Basin, north of the Thuringian Forest. It sits in the middle of an almost straight line of cities consisting of the six largest Thuringian cities forming the central metropolitan corridor of the state, the "Thuringian City Chain" ('' Thüringer Städtekette'') with more than 500,000 inhabitants, stretching from Eisenach in the west, via Gotha, Erfurt, Weimar and Jena, to Gera in the east.

Mathematics Genealogy Project
The Mathematics Genealogy Project (MGP) is a web-based database for the academic genealogy of mathematicians.. By 31 December 2021, it contained information on 274,575 mathematical scientists who contributed to research-level mathematics. For a typical mathematician, the project entry includes graduation year, thesis title (in its Mathematics Subject Classification), '' alma mater'', doctoral advisor, and doctoral students.. Origin of the database The project grew out of founder Harry Coonce's desire to know the name of his advisor's advisor.. Coonce was Professor of Mathematics at Minnesota State University, Mankato, at the time of the project's founding, and the project went online there in fall 1997.Mulcahy, Colm;The Mathematics Genealogy Project Comes of Age at Twenty-one(PDF) AMS Notices (May 2017) Coonce retired from Mankato in 1999, and in fall 2002 the university decided that it would no longer support the project.

Christian Ernst Wendt
Christians () are people who follow or adhere to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. The words ''Christ'' and ''Christian'' derive from the Koine Greek title ''Christós'' (Χριστός), a translation of the Biblical Hebrew term ''mashiach'' (מָשִׁיחַ) (usually rendered as ''messiah'' in English). While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term ''Christian'' used as an adjective is descriptive of anything associated with Christianity or Christian churches, or in a proverbial sense "all that is noble, and good, and Christ-like." It does not have a meaning of 'of Christ' or 'related or pertaining to Christ'. According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. Today, about 37% of all Christians live in the Ameri ...

Martin Ohm
Martin Ohm (May 6, 1792 in Erlangen – April 1, 1872 in Berlin) was a German mathematician and a younger brother of physicist Georg Ohm. Biography He earned his doctorate in 1811 at Friedrich-Alexander-University, Erlangen-Nuremberg where his advisor was Karl Christian von Langsdorf. In 1817, he was appointed professor of mathematics and physics in the gymnasium at Thorn. In 1821 he moved to Berlin, and in 1839 became a full professor in the University of Berlin. He delivered courses of lectures at the academy of architecture from 1824 to 1831, and at the schools of artillery and engineering from 1833 to 1852; and he also taught in the military school from 1826 to 1849. Work Ohm was the first to fully develop the theory of the exponential ''a''''b'' when both ''a'' and ''b'' are complex numbers in 1823. The 1835 second edition of Ohm's textbook, ''Die reine Elementar Mathematik'' was the first time that Euclid's 'extreme and mean ratio' was given the name of the " golden sect ...

Bavarian Academy Of Sciences
The Bavarian Academy of Sciences and Humanities (german: Bayerische Akademie der Wissenschaften) is an independent public institution, located in Munich. It appoints scholars whose research has contributed considerably to the increase of knowledge within their subject. The general goal of the academy is the promotion of interdisciplinary encounters and contacts and the cooperation of representatives of different subjects. History On 12 October 1758 the lawyer Johann Georg von Lori (1723–1787), Privy Counsellor at the College of Coinage and Mining in Munich, founded the ''Bayerische Gelehrte Gesellschaft'' (Learned Society of Bavaria). This led to the foundation by Maximilian III Joseph, Elector of Bavaria, of the Bavarian Academy of Sciences and Humanities on 28 March 1759. Count Sigmund von Haimhausen was the first president. The Academy's foundation charter specifically mentions the Parnassus Boicus, an earlier learned society. Originally, the Academy consisted of two divis ...

Vilnius University
Vilnius University ( lt, Vilniaus universitetas) is a public research university, oldest in the Baltic states and in Northern Europe outside the United Kingdom (or 6th overall following foundations of Oxford, Cambridge, St. Andrews, Glasgow and Aberdeen). Today it is Lithuania's leading academic institution, ranked among the top 400 ( QS) or top 800 ( ARWU) universities worldwide. As of 2022 QS ranks VU as 8th in CEE (ex. Russia); an ARWU equivalent would be 11th. The university was founded in 1579 as the Jesuit Academy (College) of Vilnius by Stephen Báthory, Grand Duke of Lithuania and King of Poland. It was the third oldest university (after the Cracow Academy and the Albertina) in the Polish–Lithuanian Commonwealth. Due to the failure of the November Uprising (1830–1831), the university was closed down and suspended its operation until 1919. In the aftermath of World War I, the university saw failed attempts to restart it by the local Polish Society of Friends of Scie ...

Georg Ohm
Georg Simon Ohm (, ; 16 March 1789 – 6 July 1854) was a German physicist and mathematician. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relation is called Ohm's law, and the ohm, the unit of electrical resistance, is named after him. Biography Early life Georg Simon Ohm was born into a Protestant family in Erlangen, Brandenburg-Bayreuth (then part of the Holy Roman Empire), son to locksmith Johann Wolfgang Ohm, and Maria Elizabeth Beck, daughter of a tailor in Erlangen. Although his parents had not been formally educated, Ohm's father was a respected man who had educated himself to a high level and was able to give his sons an excellent education through his own teachings. Of the seven children of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
