51Abstract analytic number theory — is a branch of mathematics which takes the ideas and techniques of classical analytic number theory and applies them to a variety of different mathematical fields. The classical prime number theorem serves as a prototypical example, and the… …
52Typographical Number Theory — (also known as TNT) is a formal axiomatic system describing the natural numbers that appears in Douglas Hofstadter s book Gödel, Escher, Bach. It is an implementation of Peano arithmetic that Hofstadter uses to help explain Gödel s incompleteness …
53Extended real number line — Positive infinity redirects here. For the band, see Positive Infinity. In mathematics, the affinely extended real number system is obtained from the real number system R by adding two elements: +∞ and −∞ (read as positive infinity and negative… …
54Total angular momentum quantum number — In quantum mechanics, the total angular quantum momentum numbers parameterize the total angular momentum of a given particle, by combining its orbital angular momentum and its intrinsic angular momentum (i.e., its spin).If s is the particle s… …
55prime number theorem — Math. the theorem that the number of prime numbers less than or equal to a given number is approximately equal to the given number divided by its natural logarithm. [1660 70] * * * ▪ mathematics formula that gives an approximate value for the… …
56Constructible number — For numbers constructible in the sense of set theory, see Constructible universe. A point in the Euclidean plane is a constructible point if, given a fixed coordinate system (or a fixed line segment of unit length), the point can be constructed… …
57Ekman number — The Ekman number, named for V. Walfrid Ekman, is a dimensionless number used in describing geophysical phenomena in the oceans and atmosphere. It characterises the ratio of viscous forces in a fluid to the fictitious forces arising from planetary …

59The Number Painter — The Number Painter, also known as the Mad Painter, was a character on Sesame Street . He appeared in a total of ten skits which premiered on February 23, 1972, often repeated in episodes until 1988.The Number Painter character was played by Paul… …
60Poly-Bernoulli number — In mathematics, poly Bernoulli numbers, denoted as B {n}^{(k)}, were defined by M. Kaneko as:{Li {k}(1 e^{ z}) over 1 e^{ x=sum {n=0}^{infty}B {n}^{(k)}{x^{n}over n!}where Li is the polylogarithm. The B {n}^{(1)} are the usual Bernoulli… …
