e. Squaring the circle is a problem in geometry first proposed in Greek mathematics. It is the challenge of constructing a square with the area of a given circle by using only a finite number of steps with a compass and straightedge. The difficulty of the problem raised the question of whether specified axioms of Euclidean geometry concerning ...
Reddit ( / ˈrɛdɪt /) is an American social news aggregation, content rating, and forum social network. Registered users (commonly referred to as "Redditors") submit content to the site such as links, text posts, images, and videos, which are then voted up or down ("upvoted" or "downvoted") by other members.

Reduced chi-squared statistic. In statistics, the reduced chi-square statistic is used extensively in goodness of fit testing. It is also known as mean squared weighted deviation ( MSWD) in isotopic dating [ 1] and variance of unit weight in the context of weighted least squares. [ 2][ 3] Its square root is called regression standard error, [ 4 ...

A Jordan curve or a simple closed curve in the plane R 2 is the image C of an injective continuous map of a circle into the plane, φ: S 1 → R 2.A Jordan arc in the plane is the image of an injective continuous map of a closed and bounded interval [a, b] into the plane.
A mound in the Great Circle Earthworks One end of the Great Circle Earthworks, part of the Newark Earthworks. The 1,200-foot (370 m)-wide Newark Earthworks Great Circle (located in Heath, OH) is one of the largest circular earthworks in the Americas, at least in construction effort. A 5-foot (1.5 m) deep moat is encompassed by walls that are 8 ...
Wrestling ring. A ring used by Detroit's Big Time Wrestling in 1972. A wrestling ring, also known as the squared circle, is the stage on which a professional wrestling match usually occurs. It is similarly constructed to a boxing ring and is traditionally square -shaped.
Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane. In topology, it is often denoted as S1 because it is a one-dimensional unit n -sphere. [ 2][ note 1]
