Albert Wangerin
Friedrich Heinrich Albert Wangerin (November 18, 1844 – October 25, 1933) was a German mathematician. Early life Wangerin was born on November 18, 1844 in Greifenberg Pomerania, Prussia (now Gryfice, Poland). He studied at the gymnasium at Greifenberg and completed his final examination with an "excellent" grade in 1862. In spring 1862, Wangerin entered the University of Halle-Wittenberg, where he studied Mathematics and Physics. He was taught by mathematicians Eduard Heine and Carl Neumann. In 1864 he moved to the University of Königsberg. He worked under the supervision of German mathematician Franz Ernst Neumann. He competed his doctorate from Königsberg University on March 16, 1866. His doctorate thesis was ''De annulis Newtonianis''. Academic career After he completing his doctorate, Wangerin took the examinations to become a school teacher. From 1866 to 1867, he trained at the Friedrichswerdersche Gymnasium, Berlin. From 1867 to 1876, he taught mathematics at s ...

Gryfice
Gryfice (pronounced ; Kashubian: ''Grëfice''; formerly german: Greifenberg)". 1880. is a historic town in Pomerania, north-western Poland, with 16,600 inhabitants (2017). It is the capital of Gryfice County in West Pomeranian Voivodeship (since 1999), previously in Szczecin Voivodeship (1975–1998). The town is situated approximately 22 kilometres from the Baltic Sea coast and seaside resorts. History Middle Ages The region was part of Poland during the reign of the first Polish rulers Mieszko I and Bolesław I the Brave. The Battle of Niekładź took place in the area of Gryfice in 1121, in which Polish ruler Bolesław III Wrymouth defeated Wartislaw I, Duke of Pomerania and Swantopolk I, Duke of Pomerania. The area was part of the Duchy of Pomerania, a vassal state of Poland, which later on separated itself from Poland as a result of the fragmentation of Poland. In 1262 Wartislaw III, Duke of Pomerania founded a town under Lübeck law on the Rega river to attract German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Heine
Heinrich Eduard Heine (16 March 1821 – 21 October 1881) was a German mathematician. Heine became known for results on special functions and in real analysis. In particular, he authored an important treatise on spherical harmonics and Legendre functions (''Handbuch der Kugelfunctionen''). He also investigated basic hypergeometric series. He introduced the Mehler–Heine formula. Biography Heinrich Eduard Heine was born on 16 March 1821 in Berlin, as the eighth child of banker Karl Heine and his wife Henriette Märtens. Eduard was initially home schooled, then studied at the Friedrichswerdersche Gymnasium and Köllnische Gymnasium in Berlin. In 1838, after graduating from gymnasium, he enrolled at the University of Berlin, but transferred to the University of Göttingen to attend the mathematics lectures of Carl Friedrich Gauss and Moritz Stern. In 1840 Heine returned to Berlin, where he studied mathematics under Peter Gustav Lejeune Dirichlet, while also attending classes o ...

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] |
People From Gryfice
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Uppsala University
Uppsala University ( sv, Uppsala universitet) is a public university, public research university in Uppsala, Sweden. Founded in 1477, it is the List of universities in Sweden, oldest university in Sweden and the Nordic countries still in operation. The university rose to significance during the rise of Swedish Empire, Sweden as a great power at the end of the 16th century and was then given a relative financial stability with a large donation from King Gustavus Adolphus of Sweden, Gustavus Adolphus in the early 17th century. Uppsala also has an important historical place in Swedish national culture, identity and for the Swedish establishment: in historiography, literature, politics, and music. Many aspects of Swedish academic culture in general, such as the white student cap, originated in Uppsala. It shares some peculiarities, such as the student nation system, with Lund University and the University of Helsinki. Uppsala belongs to the Coimbra Group of European universities a ...

Bessel Function
Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions of Bessel's differential equation x^2 \frac + x \frac + \left(x^2 - \alpha^2 \right)y = 0 for an arbitrary complex number \alpha, the ''order'' of the Bessel function. Although \alpha and -\alpha produce the same differential equation, it is conventional to define different Bessel functions for these two values in such a way that the Bessel functions are mostly smooth functions of \alpha. The most important cases are when \alpha is an integer or half-integer. Bessel functions for integer \alpha are also known as cylinder functions or the cylindrical harmonics because they appear in the solution to Laplace's equation in cylindrical coordinates. Spherical Bessel functions with half-integer \alpha are obtained when the Helmholtz equation is solved in spherical coordinates. Applications of Bessel functions The Bessel function is a generalizat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamé Function
In mathematics, a Lamé function, or ellipsoidal harmonic function, is a solution of Lamé's equation, a second-order ordinary differential equation. It was introduced in the paper . Lamé's equation appears in the method of separation of variables applied to the Laplace equation in elliptic coordinates. In some special cases solutions can be expressed in terms of polynomials called Lamé polynomials. The Lamé equation Lamé's equation is :\frac + (A+B\weierp(x))y = 0, where ''A'' and ''B'' are constants, and \wp is the Weierstrass elliptic function. The most important case is when B\weierp(x) = - \kappa^2 \operatorname^2x , where \operatorname is the elliptic sine function, and \kappa^2 = n(n+1)k^2 for an integer ''n'' and k the elliptic modulus, in which case the solutions extend to meromorphic functions defined on the whole complex plane. For other values of ''B'' the solutions have branch points. By changing the independent variable to t with t=\operatorname x, ...
