41Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics …
42Nietzsche, Friedrich Wilhelm — Nietzsche Robin Small LIFE AND PERSONALITY Friedrich Wilhelm Nietzsche (1844–1900) is one of those thinkers whose personalities cannot easily be separated from their achievements in philosophy. This is not because his life was an unusually… …
43Interpretation of quantum mechanics — An interpretation of quantum mechanics is a statement which attempts to explain how quantum mechanics informs our understanding of nature. Although quantum mechanics has received thorough experimental testing, many of these experiments are open… …
44Non-Newtonian calculus — The phrase Non Newtonian calculus used by Grossman and KatzGrossman and Katz. Non Newtonian Calculus , ISBN 0912938013, Lee Press, 1972.] describes a variety of alternatives to the classical calculus of Isaac Newton and Gottfried Leibniz.There… …

46Arc length — Determining the length of an irregular arc segment is also called rectification of a curve. Historically, many methods were used for specific curves. The advent of infinitesimal calculus led to a general formula that provides closed form… …
47Boolean algebras canonically defined — Boolean algebras have been formally defined variously as a kind of lattice and as a kind of ring. This article presents them more neutrally but equally formally as simply the models of the equational theory of two values, and observes the… …
48Eigenvalue, eigenvector and eigenspace — In mathematics, given a linear transformation, an Audio|De eigenvector.ogg|eigenvector of that linear transformation is a nonzero vector which, when that transformation is applied to it, changes in length, but not direction. For each eigenvector… …
49John von Neumann — Von Neumann redirects here. For other uses, see Von Neumann (disambiguation). The native form of this personal name is Neumann János. This article uses the Western name order. John von Neumann …
50Cyclic order — In mathematics, a cyclic order is a way to arrange a set of objects in a circle.[nb] Unlike most structures in order theory, a cyclic order cannot be modeled as a binary relation a < b . One does not say that east is more clockwise than west.… …
