Applied Mathematics
Applied mathematics is the application of mathematical methods by different fields such as physics, engineering, medicine, biology, finance, business, computer science, and industry. Thus, applied mathematics is a combination of mathematical science and specialized knowledge. The term "applied mathematics" also describes the professional specialty in which mathematicians work on practical problems by formulating and studying mathematical models. In the past, practical applications have motivated the development of mathematical theories, which then became the subject of study in pure mathematics where abstract concepts are studied for their own sake. The activity of applied mathematics is thus intimately connected with research in pure mathematics. History Historically, applied mathematics consisted principally of applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variational ...

Dorpat University
The University of Tartu (UT; et, Tartu Ülikool; la, Universitas Tartuensis) is a university in the city of Tartu in Estonia. It is the national university of Estonia. It is the only classical university in the country, and also its biggest and most prestigious university. It was founded under the name of ''Academia Gustaviana'' in 1632 by Baron Johan Skytte, the Governor-General (1629–1634) of Swedish Livonia, Ingria, and Karelia, with the required ratification provided by his long-time friend and former student – from age 7 –, King Gustavus Adolphus, shortly before the king's death on 6 November in the Battle of Lützen (1632), during the Thirty Years' War (1618–1648). Nearly 14,000 students are at the university, of whom over 1,300 are foreign students. The language of instruction in most curricula is Estonian, some more notable exceptions are taught in English, such as semiotics, applied measurement science, computer science, information technology law, and Europ ...

University Of Erlangen-Nuremberg
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''UniversitĂ  di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Johann Friedrich Pfaff
Johann Friedrich Pfaff (sometimes spelled Friederich; 22 December 1765 – 21 April 1825) was a German mathematician. He was described as one of Germany's most eminent mathematicians during the 19th century. He was a precursor of the German school of mathematical thinking, which under Carl Friedrich Gauss and his followers largely determined the lines on which mathematics developed during the 19th century. Biography He received his early education at the Carlsschule, where he met Friedrich Schiller, his lifelong friend. His mathematical capacity was noticed during his early years. He pursued his studies at Göttingen under Abraham Gotthelf Kästner, and in 1787 he went to Berlin and studied practical astronomy under J. E. Bode. In 1788, Pfaff became professor of mathematics in Helmstedt, and continued his work as a professor until that university was abolished in 1810. After this event, he became professor of mathematics at the University of Halle, where he stayed for the rest of ...

Christian Heinrich Pfaff
Christoph Heinrich Pfaff (2 March 1773, Stuttgart – 24 April 1852, Kiel, Holstein) was a German physician, chemist and physicist. Biography He graduated as a physician at the Karlsschule in Stuttgart in 1793, where he studied under Carl Friedrich Kielmeyer and became good friends with Georges Cuvier. He then went to Göttingen, where he published the results of his galvanic inquiries in ''Ueber thierische Electricität und Reizbarkeit'' ("On animal electricity and susceptibility to stimulus"). In 1797 he became an associate professor at the University of Kiel, and in 1802 was made professor of chemistry, physics and medicine there with rank at the same time as a member of the medical faculty.ADB:Pfaff, Christoph Heinrich
