Flushing, NY
Flushing is a neighborhood in the north-central portion of the New York City borough of Queens. The neighborhood is the fourth-largest central business district in New York City. Downtown Flushing is a major commercial and retail area, and the intersection of Main Street and Roosevelt Avenue at its core is the third-busiest in New York City, behind Times Square and Herald Square. Flushing was established as a settlement of New Netherland on October 10, 1645, on the eastern bank of Flushing Creek. It was named Vlissingen, after the Dutch city of Vlissingen. The English took control of New Amsterdam in 1664, and when Queens County was established in 1683, the "Town of Flushing" was one of the original five towns of Queens. In 1898, Flushing was consolidated into the City of New York. Development came in the early 20th century with the construction of bridges and public transportation. An immigrant population, composed mostly of Chinese and Koreans, settled in Flushing in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queens College, City University Of New York Faculty
Queens is a borough of New York City, coextensive with Queens County, in the U.S. state of New York. Located on Long Island, it is the largest New York City borough by area. It is bordered by the borough of Brooklyn at the western tip of Long Island to its west, and Nassau County to its east. Queens also shares water borders with the boroughs of Manhattan, the Bronx, and Staten Island (via the Rockaways). With a population of 2,405,464 as of the 2020 census, Queens is the second most populous county in the State of New York, behind Kings County (Brooklyn), and is therefore also the second most populous of the five New York City boroughs. If Queens became a city, it would rank as the fifth most-populous in the U.S. after New York City, Los Angeles, Chicago, and Houston. Approximately 47% of the residents of Queens are foreign-born. Queens is the most linguistically diverse place on Earth and is one of the most ethnically diverse counties in the United States. Queens was es ...

University Of Pennsylvania Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...

Hilbert's Fifth Problem
Hilbert's fifth problem is the fifth mathematical problem from the problem list publicized in 1900 by mathematician David Hilbert, and concerns the characterization of Lie groups. The theory of Lie groups describes continuous symmetry in mathematics; its importance there and in theoretical physics (for example quark theory) grew steadily in the twentieth century. In rough terms, Lie group theory is the common ground of group theory and the theory of topological manifolds. The question Hilbert asked was an acute one of making this precise: is there any difference if a restriction to smooth manifolds is imposed? The expected answer was in the negative (the classical groups, the most central examples in Lie group theory, are smooth manifolds). This was eventually confirmed in the early 1950s. Since the precise notion of "manifold" was not available to Hilbert, there is room for some debate about the formulation of the problem in contemporary mathematical language. Formulation of ...

Nina Baym
Nina Baym (1936–2018) was an American literary critic and literary historian. She was professor of English at the University of Illinois at Urbana-Champaign from 1963 to 2004. Before her retirement at the University of Illinois Baym was a Swanlund Endowed Chair, a Jubilee Professor of Liberal Arts & Sciences and a Center of Advanced Study Professor of English. Her work in US literary criticism and history is widely credited with expanding the field to include women writers while taking the focus off "great" writers according to a supposed unchanging value judgment and placing it instead on the dynamics of literary professionalism. She is the author or editor of a number of groundbreaking works of American literary history and criticism, beginning with ''Woman's Fiction'' (Cornell, 1978), and including ''Feminism and American Literary History'' (Rutgers, 1992), ''American Women Writers and the Work of History'' (Rutgers, 1995), and ''American Women of Letters and the Nineteenth-Cen ...
