61Algorithm — Flow chart of an algorithm (Euclid s algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≤ A yields yes… …
62Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For …
63Pushout (category theory) — In category theory, a branch of mathematics, a pushout (also called a fibered coproduct or fibered sum or cocartesian square or amalgamed sum) is the colimit of a diagram consisting of two morphisms f : Z → X and g : Z → Y with a common …
64Dialetheism — is the view that some statements can be both true and false simultaneously. More precisely, it is the belief that there can be a true statement whose negation is also true. Such statements are called true contradictions , or dialetheia.… …
65E₇ — In mathematics, E7 is the name of several Lie groups and also their Lie algebras mathfrak{e} 7. It is one of the five exceptional compact simple Lie groups as well as one of the simply laced groups. E 7 has rank 7 and dimension 133. The… …
66Computability theory — For the concept of computability, see Computability. Computability theory, also called recursion theory, is a branch of mathematical logic that originated in the 1930s with the study of computable functions and Turing degrees. The field has grown …
67Method of image charges — The method of image charges (also known as the method of images and method of mirror charges) is a basic problem solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with imaginary… …
68Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …
69Langlands group — In representation theory, a branch of mathematics, the Langlands (dual) group L G (also called L group) is a group associated to a reductive group G over a field k that controls the representation theory of G . It is an extension of the absolute… …
70Mathematical beauty — An example of beauty in method a simple and elegant geometrical proof that the Pythagorean theorem is true for a particular right angled triangle. Many mathematicians derive aesthetic pleasure from their work, and from mathematics in general.… …
