Euclidean space was introduced by ancient Greeks as an abstraction of our physical space. Their great innovation, appearing in Euclid's Elements was to build and prove all geometry by starting from a few very basic properties, which are abstracted from the physical world, and cannot be mathematically proved because of the lack of more basic tools.
The number of points (n), chords (c) and regions (r G) for first 6 terms of Moser's circle problem. In geometry, the problem of dividing a circle into areas by means of an inscribed polygon with n sides in such a way as to maximise the number of areas created by the edges and diagonals, sometimes called Moser's circle problem (named after Leo Moser), has a solution by an inductive method.
Common lines and line segments on a circle, including a chord in blue. A chord (from the Latin chorda, meaning "bowstring") of a circle is a straight line segment whose endpoints both lie on a circular arc.
The Golden Triangle of Jakarta (Indonesian: Segitiga Emas Jakarta), also referred to as the Medan Merdeka–Thamrin–Sudirman Axis (Indonesian: Poros Medan Merdeka–Thamrin–Sudirman) or the Sudirman–Thamrin–Kuningan Axis (Indonesian: Poros Sudirman–Thamrin–Kuningan), is a roughly triangular area in the center of Jakarta, Indonesia, extending from Central Jakarta to South Jakarta.
In mathematics, Pascal's triangle is an infinite triangular array of the binomial coefficients which play a crucial role in probability theory, combinatorics, and algebra.In much of the Western world, it is named after the French mathematician Blaise Pascal, although other mathematicians studied it centuries before him in Persia, [1] India, [2] China, Germany, and Italy.

The list contains all the cities with the administrative designation of "national central city" (国家中心城市) and "sub-provincial city" (副省级城市) – including five "cities with independent planning status" (计划单列市) and ten large "provincial capital cities" (省会城市), as well as some large "special economic zones" (经济特区城市), "open coastal cities ...
It was discovered by Charles Messier on June 5, 1764. [4] Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars , an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the ...
