71Tutte polynomial — This article is about the Tutte polynomial of a graph. For the Tutte polynomial of a matroid, see Matroid. The polynomial x4 + x3 + x2y is the Tutte polynomial of the Bull graph. The red line shows the intersection with the plane …
72Number — For other uses, see Numbers (disambiguation). A number is a mathematical object used to count and measure. In mathematics, the definition of number has been extended over the years to include such numbers as zero, negative numbers, rational… …
73Hilbert's tenth problem — is the tenth on the list of Hilbert s problems of 1900. Its statement is as follows:Given a Diophantine equation with any number of unknown quantities and with rational integral numerical coefficients: To devise a process according to which it… …
74Euclidean geometry — A Greek mathematician performing a geometric construction with a compass, from The School of Athens by Raphael. Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described in his… …
75Newton's laws of motion — For other uses, see Laws of motion. Classical mechanics …
76Roy Meadow — Professor Sir Samuel Roy Meadow (born 1933) is a British paediatrician who rose to initial fame for his 1977 academic paper on the now controversial Munchausen Syndrome by Proxy (MSbP) and his crusade against parents who wilfully harm or kill… …
77Fermionic field — In quantum field theory, a fermionic field is a quantum field whose quanta are fermions; that is, they obey Fermi Dirac statistics. Fermionic fields obey canonical anticommutation relations rather than the canonical commutation relations of… …
78Lorentz covariance — In standard physics, Lorentz covariance is a key property of spacetime that follows from the special theory of relativity, where it applies globally. Local Lorentz covariance refers to Lorentz covariance applying only locally in an infinitesimal… …
79Euler (programming language) — Euler is a programming language created by Niklaus Wirth and Helmut Weber, conceived as an extension and generalization of ALGOL 60. The designers goal was to create a language: * which was simpler, and yet more flexible, than ALGOL 60 * that was …
80String duality — is a class of symmetries in physics that link different string theories, theories which assume that the fundamental building blocks of the universe are strings instead of point particles. Before the so called duality revolution there were… …
