Joseph Neuberg
Joseph Jean Baptiste Neuberg (30 October 1840 – 22 March 1926) was a Luxembourger mathematician who worked primarily in geometry. Biography Neuberg was born on 30 October 1840 in Luxembourg City, Luxembourg. He first studied at a local school, the Athénée de Luxembourg, then progressed to Ghent University, studying at the École normale des Sciences of the science faculty. After graduation, Neuberg taught at several institutions. Between 1862 and 1865, he taught at the École Normale de Nivelle. For the next sixteen years, he taught at the Athénée Royal d'Arlon, though he also taught at the École Normale at Bruges from 1868 onwards. Retrieved on 2008-09-16. Neuberg switched from his previous two schools to the Athénée Royal de Liège in 1878. He became an extraordinary professor in the university in the same city in 1884, and was promoted to ordinary professor in 1887. He held this latter position until his retirement in 1910.

Isodynamic Point
In Euclidean geometry, the isodynamic points of a triangle are points associated with the triangle, with the properties that an inversion centered at one of these points transforms the given triangle into an equilateral triangle, and that the distances from the isodynamic point to the triangle vertices are inversely proportional to the opposite side lengths of the triangle. Triangles that are similar to each other have isodynamic points in corresponding locations in the plane, so the isodynamic points are triangle centers, and unlike other triangle centers the isodynamic points are also invariant under Möbius transformations. A triangle that is itself equilateral has a unique isodynamic point, at its centroid(as well as its orthocenter, its incenter, and its circumcenter, which are concurrent); every non-equilateral triangle has two isodynamic points. Isodynamic points were first studied and named by . Distance ratios The isodynamic points were originally defined from certain eq ...

1840 Births
__NOTOC__ Year 184 ( CLXXXIV) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Eggius and Aelianus (or, less frequently, year 937 ''Ab urbe condita''). The denomination 184 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Alumni Of The Athénée De Luxembourg
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating (Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the s ...

19th-century 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] |

Luxembourgian Educators
Luxembourgish ( ; also ''Luxemburgish'', ''Luxembourgian'', ''Letzebu(e)rgesch''; Luxembourgish: ) is a West Germanic language that is spoken mainly in Luxembourg. About 400,000 people speak Luxembourgish worldwide. As a standard form of the Moselle Franconian language, Luxembourgish has similarities with other varieties of High German and the wider group of West Germanic languages. The status of Luxembourgish as an official language in Luxembourg and the existence there of a regulatory body have removed Luxembourgish, at least in part, from the domain of Standard German, its traditional . History Luxembourgish was considered a German dialect like many others until about World War II but then it underwent ausbau, that is it created its own standard form in vocabulary, grammar and spelling and therefore is seen today as an independent language, an ausbau language. Due to the fact that Luxembourgish has a maximum of some 285,000 native speakers, resources in the language lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Mathesis: Recueil Mathématique'' was a Belgian scientific journal for elementary mathematics, established in 1881 by Paul Mansion and Joseph Jean Baptiste Neuberg Joseph Jean Baptiste Neuberg (30 October 1840 – 22 March 1926) was a Luxembourger mathematician who worked primarily in geometry. Biography Neuberg was born on 30 October 1840 in Luxembourg City, Luxembourg. He first studied at a local scho .... An earlier Belgian mathematics journal, ''Nouvelle Correspondance Mathématique'', was established in 1874 by Mansion and Neuberg together with Eugène Catalan. In 1880, ''Nouvelle Correspondance'' ceased publication, and Mansion and Neuberg together launched its successor, ''Mathesis'', in 1881. ''Mathesis'' ceased publication in 1915 because of the war in Europe, but restarted again under the editorship of Neuberg and Adolphe Mineur in 1922 as the official journal of the Belgian Mathematical Society, which itself was founded in 1921.

Jean Garnier
Jean Garnier (11 November 1612 – 26 November 1681) was a French Jesuit church historian, patristic scholar, and moral theologian. Life He was born at Paris, entered the Society of Jesus at the age of sixteen, and, after a distinguished course of study, taught at first the humanities, then philosophy, at Clermont-Ferrand (1643–1653), and theology at Bourges (1653–1681). In 1681, he was sent to Rome on business of his order, fell ill on the way and died at Bologna.

Works In 1618, he published for the first time the ''Libellus fidei'', sent to the Holy See during the Pelagian controversy by Julian, Bishop of Eclanum in Apulia. Garnier added notes and an historical commentary. The ''Libellus'' also found a place in Garnier's later work on Marius Mercator. In 1655, he wrote ''Regulae fidei catholicae de gratia Dei per ...

Lambert Quetelet
Lambert Adolphe Jacques Quetelet FRSF or FRSE (; 22 February 1796 – 17 February 1874) was a Belgian astronomer, mathematician, statistician and sociologist who founded and directed the Brussels Observatory and was influential in introducing statistical methods to the social sciences. His name is sometimes spelled with an accent as ''Quételet''. He also founded the science of anthropometry and developed the body mass index (BMI) scale, originally called the Quetelet Index. His work on measuring human characteristic to determine the ideal ''l'homme moyen'' ("the average man"), played a key role in the origins of eugenics. Biography Adolphe was born in Ghent (which, at the time was a part of the new French Republic). He was the son of François-Augustin-Jacques-Henri Quetelet, a Frenchman and Anne Françoise Vandervelde, a Flemish woman.
