Infinity: Facts and Speculations of Science is a popular science book by theoretical physicist George Gamow, first published in 1947, but still (as of 2020) available in print and electronic formats. The book explores a wide range of fundamental concepts in mathematics and science, written at a level understandable by middle school students up ...
Penrose diagram of an infinite Minkowski universe, horizontal axis u, vertical axis v. In theoretical physics, a Penrose diagram (named after mathematical physicist Roger Penrose) is a two-dimensional diagram capturing the causal relations between different points in spacetime through a conformal treatment of infinity.
In mathematics, the Riemann sphere, named after Bernhard Riemann, [1] is a model of the extended complex plane (also called the closed complex plane): the complex plane plus one point at infinity. This extended plane represents the extended complex numbers , that is, the complex numbers plus a value ∞ {\displaystyle \infty } for infinity .
The futures wheel is a method for graphical visualisation of direct and indirect future consequences of a particular change or development. It was invented by Jerome C. Glenn in 1971, when he was a student at the Antioch Graduate School of Education (now Antioch University New England ).
Ends of graphs were defined by Rudolf Halin () in terms of equivalence classes of infinite paths. [1] A ray in an infinite graph is a semi-infinite simple path; that is, it is an infinite sequence of vertices ,,, … in which each vertex appears at most once in the sequence and each two consecutive vertices in the sequence are the two endpoints of an edge in the graph.
Klauber's 1932 paper describes a triangle in which row n contains the numbers (n − 1) 2 + 1 through n 2. As in the Ulam spiral, quadratic polynomials generate numbers that lie in straight lines. Vertical lines correspond to numbers of the form k 2 − k + M. Vertical and diagonal lines with a high density of prime numbers are evident in the ...
"Infinity" is a 2012 song recorded by music production and DJ duo Infinity Ink. The duo found fame in 2012 through "Games" on the Hot Creations label followed quickly by "Infinity" on the Crosstown Rebels label, released on 14 May 2012. The single was certified platinum by the Belgian Entertainment Association. [1]
Any finite natural number can be used in at least two ways: as an ordinal and as a cardinal. Cardinal numbers specify the size of sets (e.g., a bag of five marbles), whereas ordinal numbers specify the order of a member within an ordered set [9] (e.g., "the third man from the left" or "the twenty-seventh day of January").
