Vieri Benci
Vieri Benci (born May 9, 1949) is an Italian mathematician who worked at the University of Pisa. He has contributed to various fields of mathematics such as the partial differential equations (PDEs), mathematical physics, Hamiltonian dynamics, soliton theory, the geometry of general relativity, nonstandard analysis and the foundations of mathematics. In the latter two disciplines he introduced, in collaboration with M. Di Nasso and M. Forti, a theory of numerosity that refines the cantorian theory of cardinality; he has also worked on applications of nonstandard analysis to probability. Education and career After winning the admission competition to the Scuola Normale Superiore in Pisa in 1968, ranking first, he graduated in mathematics in 1972 under the guidance of Guido Stampacchia at the University of Pisa, at the same time obtaining the diploma as a normalist. He continued his studies at the University of Paris VI (1972-74) and at Courant Institute of Mathematical Scienc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vieri Benci 06 11 2014
Christian Vieri (; born 12 July 1973), commonly known as Bobo Vieri, is an Italian former professional footballer who played as a centre forward. Having been born in Italy, Vieri moved with his family to Australia as a child, before returning to Italy to pursue his professional career at a young age. He then spent the bulk of his career playing in the Serie A. In March 2004, he was named in the FIFA 100, a list of the 125 greatest living footballers selected by Pelé as a part of FIFA's centenary celebrations. A prolific goalscorer, for a number of years, he was regarded as one of the best strikers of this generation, leading to him becoming the world's most expensive player in 1999 when Inter Milan paid Lazio £32 million (€43 million) for his services. Something of a footballing nomad, Vieri played for no fewer than 12 clubs throughout his career, mainly in Italy, but also in Spain and France. He started his career with Torino in 1991, but his most notable and suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanford Encyclopedia Of Philosophy
The ''Stanford Encyclopedia of Philosophy'' (''SEP'') is a freely available online philosophy resource published and maintained by Stanford University, encompassing both an online encyclopedia of philosophy and peer-reviewed original publication. Each entry is written and maintained by an expert in the field, including professors from many academic institutions worldwide. Authors contributing to the encyclopedia give Stanford University the permission to publish the articles, but retain the copyright to those articles. Approach and history As of August 5, 2022, the ''SEP'' has 1,774 published entries. Apart from its online status, the encyclopedia uses the traditional academic approach of most encyclopedias and academic journals to achieve quality by means of specialist authors selected by an editor or an editorial committee that is competent (although not necessarily considered specialists) in the field covered by the encyclopedia and peer review. The encyclopedia was created i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematical Reviews
''Mathematical Reviews'' is a journal published by the American Mathematical Society (AMS) that contains brief synopses, and in some cases evaluations, of many articles in mathematics, statistics, and theoretical computer science. The AMS also publishes an associated online bibliographic database called MathSciNet, which contains an electronic version of ''Mathematical Reviews''. Reviews Mathematical Reviews was founded by Otto E. Neugebauer in 1940 as an alternative to the German journal '' Zentralblatt für Mathematik'', which Neugebauer had also founded a decade earlier, but which under the Nazis had begun censoring reviews by and of Jewish mathematicians. The goal of the new journal was to give reviews of every mathematical research publication. As of November 2007, the ''Mathematical Reviews'' database contained information on over 2.2 million articles. The authors of reviews are volunteers, usually chosen by the editors because of some expertise in the area of the articl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nonstandard Analysis
The history of calculus is fraught with philosophical debates about the meaning and logical validity of fluxions or infinitesimal numbers. The standard way to resolve these debates is to define the operations of calculus using (ε, δ)-definition of limit, limits rather than infinitesimals. Nonstandard analysis instead reformulates the calculus using a logically rigorous notion of infinitesimal numbers. Nonstandard analysis originated in the early 1960s by the mathematician Abraham Robinson. He wrote: ... the idea of infinitely small or ''infinitesimal'' quantities seems to appeal naturally to our intuition. At any rate, the use of infinitesimals was widespread during the formative stages of the Differential and Integral Calculus. As for the objection ... that the distance between two distinct real numbers cannot be infinitely small, Gottfried Wilhelm Leibniz argued that the theory of infinitesimals implies the introduction of ideal numbers which might be infinitely small or inf ...

Numerosity
Numerosity may refer to: Cognitive science * Numerical cognition, a subdiscipline of cognitive science that studies the cognitive, developmental and neural bases of numbers and mathematics. Mathematics * Numerosity (mathematics), a theory for counting the number of elements of sets having infinite elements. It is a theory that refines Cantor's cardinality. Psychology * Number sense In psychology, number sense is the term used for the hypothesis that some animals, particularly humans, have a biologically determined ability that allows them to represent and manipulate large numerical quantities. The term was popularized by ..., a term used for the hypothesis that some animals, particularly humans, have a biologically determined ability that allows them to represent and manipulate large numerical quantities.

Maxwell's Equations
Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, Electrical network, electric and Magnetic circuit, magnetic circuits. The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors, wireless communication, lenses, radar, etc. They describe how electric field, electric and magnetic fields are generated by electric charge, charges, electric current, currents, and changes of the fields.''Electric'' and ''magnetic'' fields, according to the theory of relativity, are the components of a single electromagnetic field. The equations are named after the physicist and mathematician James Clerk Maxwell, who, in 1861 and 1862, published an early form of the equations that included the Lorentz force law. Maxwell first used the equations to propose that ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Partial Derivative
In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry. The partial derivative of a function f(x, y, \dots) with respect to the variable x is variously denoted by It can be thought of as the rate of change of the function in the x-direction. Sometimes, for the partial derivative of z with respect to x is denoted as \tfrac. Since a partial derivative generally has the same arguments as the original function, its functional dependence is sometimes explicitly signified by the notation, such as in: f'_x(x, y, \ldots), \frac (x, y, \ldots). The symbol used to denote partial derivatives is ∂. One of the first known uses of this symbol in mathematics is by Marquis de Condorcet from 1770, who used it for partial differ ...

New York University
New York University (NYU) is a private university, private research university in New York City, New York, United States. Chartered in 1831 by the New York State Legislature, NYU was founded in 1832 by Albert Gallatin as a Nondenominational Christianity, non-denominational all-male institution near New York City Hall, City Hall based on a curriculum focused on a secular education. The university moved in 1833 and has maintained its main campus in Greenwich Village surrounding Washington Square Park. Since then, the university has added an engineering school in Brooklyn's MetroTech Center and graduate schools throughout Manhattan.
