Saly Ruth Ramler
Saly Ruth Ramler (1894–1993), also known as Saly Ruth Struik, was the first woman to receive a mathematics PhD from the German University in Prague, now known as Charles University. Life and work Her 1919 dissertation, on the axioms of affine geometry, was supervised by Gerhard Kowalewski and Georg Alexander Pick. She married the Dutch mathematician and historian of mathematics Dirk Jan Struik in 1923. Between 1924 and 1926, the pair traveled Europe and met many prominent mathematicians, using Dirk Struik's Rockefeller fellowship. In 1926, they emigrated to the United States, and Dirk Struik accepted a position at MIT The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, United States.

Dirk Jan Struik
Dirk Jan Struik (September 30, 1894 – October 21, 2000) was a Dutch-born American (since 1934) mathematician, historian of mathematics, and Marxist theoretician who spent most of his life in the U.S. Early life Dirk Jan Struik was born in 1894 in Rotterdam, Netherlands. His father Hendrik Jan Struik was a grammar school teacher with a passion for mathematics and history. Nearly a century later when Dirk received a Kenneth O. May Medal, he began his acceptance speech with a tribute to Hendrik for cultivating his son's appetite for knowledge. From 1906 to 1911, Dirk attended the Hogere Burgers School in Rotterdam, where he was introduced to left-wing politics and socialism by a favorite math teacher, G. W. Ten Dam. After entering the University of Leiden in 1912, Struik showed a strong aptitude for mathematics and physics. He was taught by the eminent professors Willem de Sitter, Hendrik Lorentz and Paul Ehrenfest. The unconventional Ehrenfest was said to have exerted th ...

Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a Private university, private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of modern technology and science. In response to the increasing Technological and industrial history of the United States, industrialization of the United States, William Barton Rogers organized a school in Boston to create "useful knowledge." Initially funded by a land-grant universities, federal land grant, the institute adopted a Polytechnic, polytechnic model that stressed laboratory instruction in applied science and engineering. MIT moved from Boston to Cambridge in 1916 and grew rapidly through collaboration with private industry, military branches, and new federal basic research agencies, the formation of which was influenced by MIT faculty like Vannevar Bush. In the late twentieth century, MIT became a leading center for research in compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles University Alumni
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age. In some Slavic languages, the name ''Drago (given name), Drago'' (and variants: ''Drago ...

People From Kolomyia
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Affine Geometry
In mathematics, affine geometry is what remains of Euclidean geometry when ignoring (mathematicians often say "forgetting") the metric notions of distance and angle. As the notion of '' parallel lines'' is one of the main properties that is independent of any metric, affine geometry is often considered as the study of parallel lines. Therefore, Playfair's axiom (Given a line and a point not on , there is exactly one line parallel to that passes through .) is fundamental in affine geometry. Comparisons of figures in affine geometry are made with affine transformations, which are mappings that preserve alignment of points and parallelism of lines. Affine geometry can be developed in two ways that are essentially equivalent. In synthetic geometry, an affine space is a set of ''points'' to which is associated a set of lines, which satisfy some axioms (such as Playfair's axiom). Affine geometry can also be developed on the basis of linear algebra. In this context an affine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles University
Charles University (CUNI; , UK; ; ), or historically as the University of Prague (), is the largest university in the Czech Republic.

He requested his friend and ally, Pope Clement VI, to create the university. On 26 January 1347, the pope issued the bull establishing a university in Prague, modeled on the University of Paris, with all four faculty (division), faculties, including theology.
