Ray Solomonoff (July 25, 1926 – December 7, 2009) [1] [2] was an American mathematician who invented algorithmic probability, [3] his General Theory of Inductive Inference (also known as Universal Inductive Inference), [4] and was a founder of algorithmic information theory. [5]
This is a timeline of pure and applied mathematics history.It is divided here into three stages, corresponding to stages in the development of mathematical notation: a "rhetorical" stage in which calculations are described purely by words, a "syncopated" stage in which quantities and common algebraic operations are beginning to be represented by symbolic abbreviations, and finally a "symbolic ...
Roy Patrick Kerr CNZM FRS FRSNZ (/ k ɜːr /; born 16 May 1934) is a New Zealand mathematician who discovered the Kerr geometry, an exact solution to the Einstein field equation of general relativity. His solution models the gravitational field outside an uncharged rotating massive object, including a rotating black hole.
The equation can be written in parametric form using the trigonometric functions sine and cosine as = + , = + , where t is a parametric variable in the range 0 to 2 π, interpreted geometrically as the angle that the ray from (a, b) to (x, y) makes with the positive x axis.
[8] [9] Islamic mathematics, in turn, developed and expanded the mathematics known to these civilizations. [10] Contemporaneous with but independent of these traditions were the mathematics developed by the Maya civilization of Mexico and Central America , where the concept of zero was given a standard symbol in Maya numerals .

Half-line (geometry) or ray, half of a line split at an initial point Directed half-line or ray, half of a directed or oriented line split at an initial point; Ray (graph theory), an infinite sequence of vertices such that 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
