Emil Weyr
Emil Weyr (31 August / 1 September 1848 – 25 January 1894) was an Austrian-Czech mathematician, known for his numerous publications on geometry. Born in Prague, Weyr attended the Prague Polytechnic, where he was taught by Heinrich Durège and Otto Wilhelm Fiedler. Biography Early life The birthdate of Weyr is disputed. Parish records indicate that Emil was born in Prague, on 1 September 1848, whereas his family believed he was born on 31 August 1848 and celebrated his birthday on this date. His parents were František Weyr and Marie Rumplova. František was a mathematics professor at a secondary school Emil would later attend. Emil's parents had ten children, five sons and five daughters. One of his brothers Eduard Weyr, was also a mathematician. Early Education Emil attended Our Lady of the Snows primary school in 1854. Following this he would study at the German secondary school on Mikulandská street in Prague from 1859. By this age Emil was already fascinated by m ...

Prague
Prague ( ; cs, Praha ; german: Prag, ; la, Praga) is the capital and largest city in the Czech Republic, and the historical capital of Bohemia. On the Vltava river, Prague is home to about 1.3 million people. The city has a temperate oceanic climate, with relatively warm summers and chilly winters. Prague is a political, cultural, and economic hub of central Europe, with a rich history and Romanesque, Gothic, Renaissance and Baroque architectures. It was the capital of the Kingdom of Bohemia and residence of several Holy Roman Emperors, most notably Charles IV (r. 1346–1378). It was an important city to the Habsburg monarchy and Austro-Hungarian Empire. The city played major roles in the Bohemian and the Protestant Reformations, the Thirty Years' War and in 20th-century history as the capital of Czechoslovakia between the World Wars and the post-war Communist era. Prague is home to a number of well-known cultural attractions, many of which survived the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Mach
Ernst Waldfried Josef Wenzel Mach ( , ; 18 February 1838 – 19 February 1916) was a Moravian-born Austrian physicist and philosopher, who contributed to the physics of shock waves. The ratio of one's speed to that of sound is named the Mach number in his honour. As a philosopher of science, he was a major influence on logical positivism and American pragmatism. Through his criticism of Newton's theories of space and time, he foreshadowed Einstein's theory of relativity. Biography Mach was born in Chrlice (german: Chirlitz), Moravia (then in the Austrian Empire, now part of Brno in the Czech Republic). His father, who had graduated from Charles-Ferdinand University in Prague, acted as tutor to the noble Brethon family in Zlín in eastern Moravia. His grandfather, Wenzl Lanhaus, an administrator of the Chirlitz estate, was also master builder of the streets there. His activities in that field later influenced Ernst Mach's theoretical work. Some sources give Mach's birthplac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1848 Births
1848 is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most failed in their immediate aims, they significantly altered the political and philosophical landscape and had major ramifications throughout the rest of the century.

Gustav Von Escherich
Gustav Ritter von Escherich (1 June 1849 – 28 January 1935) was an Austrian mathematician. Biography Born in Mantua, he studied mathematics and physics at the University of Vienna. From 1876 to 1879 he was professor at the University of Graz. In 1882 he went to the Graz University of Technology and in 1884 he went to the University of Vienna, where he also was president of the university in 1903/04. Together with Emil Weyr he founded the journal '' Monatshefte für Mathematik und Physik'' and together with Ludwig Boltzmann and Emil Müller he founded the Austrian Mathematical Society. Escherich died in Vienna. Work on hyperbolic geometry Following Eugenio Beltrami's (1868) discussion of hyperbolic geometry, Escherich in 1874 published a paper named "The geometry on surfaces of constant negative curvature". He used coordinates initially introduced by Christoph Gudermann (1830) for spherical geometry, which were adapted by Escherich using hyperbolic functions. For the case ...

Adjunct Professor
An adjunct professor is a type of academic appointment in higher education who does not work at the establishment full-time. The terms of this appointment and the job security of the tenure vary in different parts of the world, however the general definition is agreed upon. The term "Adjuncting" is a way of referring to a bona-fide part-time faculty member who has worked in an adjunct position for an institution of higher education. Terminology They may also be called an adjunct lecturer, adjunct instructor, or adjunct faculty. Collectively, they may be referred to as contingent academic labor. The rank of sessional lecturer in Canadian universities is similar to the US concept. North America In the United States, an adjunct is, in most cases, a non-tenure-track faculty member. However, it can also be a scholar or teacher whose primary employer is not the school or department with which they have adjunct status. Adjunct professors make up the majority of instructors in high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Of Czech Mathematicians And Physicists
The Union of Czech mathematicians and physicists ( cs, Jednota českých matematiků a fyziků, JČMF) is one of the oldest learned societies in Czech lands existing to this day. It was founded in 1862 as the Association for free lectures in mathematics and physics (Union of Czech mathematicians). From the beginning, its goal was improvement of teaching physics and mathematics at schools on all levels and of all types and further support and promote the development of those sciences. As a consequence of patriotic efforts, the Association was enlarged in 1869 into the Union of Czech mathematicians and physicists. Members of the Union were largely teachers at high schools and post-secondary learning institutes, and further professors at universities and scientists. In 1870, the Union started publishing the ''News of the Union of Czech mathematicians and physicists'', which in 1872 gave rise to the ''Journal for fostering mathematics and physics'' (Czech: ''Časopis pro pěstování ma ...

Felice Casorati (mathematician)
Felice Casorati (17 December 1835 – 11 September 1890) was an Italian mathematician who studied at the University of Pavia. He was born in Pavia and died in Casteggio. He is best known for the Casorati–Weierstrass theorem in complex analysis. The theorem, named for Casorati and Karl Theodor Wilhelm Weierstrass, describes the remarkable behavior of holomorphic functions near essential singularities, which is that every holomorphic function gets values from any complex neighbourhood, in any neighbourhood of the singularity. The Casorati matrix is useful in the study of linear difference equations, just as the Wronskian is useful with linear differential equations. It is calculated based on n functions of the single input variable. Works * , available at Gallica (also aGDZ.

Luigi Cremona
Antonio Luigi Gaudenzio Giuseppe Cremona (7 December 1830 – 10 June 1903) was an Italian mathematician. His life was devoted to the study of geometry and reforming advanced mathematical teaching in Italy. He worked on algebraic curves and algebraic surfaces, particularly through his paper ''Introduzione ad una teoria geometrica delle curve piane'' ("Introduction to a geometrical theory of the plane curves"), and was a founder of the Italian school of algebraic geometry. Biography Luigi Cremona was born in Pavia (Lombardy), then part of the Austrian-controlled Kingdom of Lombardy–Venetia. His youngest brother was the painter Tranquillo Cremona. In 1848, when Milan and Venice rose against Austria, Cremona, then only seventeen, joined the ranks of the Italian volunteers. He remained with them, fighting on behalf of his country's freedom, until, in 1849, the capitulation of Venice put an end to the campaign. He then returned to Pavia, where he pursued his studies at the univer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venice
Venice ( ; it, Venezia ; vec, Venesia or ) is a city in northeastern Italy and the capital of the Veneto Regions of Italy, region. It is built on a group of 118 small islands that are separated by canals and linked by over 400 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po River, Po and the Piave River, Piave rivers (more exactly between the Brenta (river), Brenta and the Sile (river), Sile).
