  2. Plane at infinity - Wikipedia

    en.wikipedia.org/wiki/Plane_at_infinity

    On the other hand, given an affine 3-space, the plane at infinity is a projective plane which is added to the affine 3-space in order to give it closure of incidence properties. Meaning that the points of the plane at infinity are the points where parallel lines of the affine 3-space will meet, and the lines are the lines where parallel planes ...

  3. Point at infinity - Wikipedia

    en.wikipedia.org/wiki/Point_at_infinity

    In an affine or Euclidean space of higher dimension, the points at infinity are the points which are added to the space to get the projective completion. [citation needed] The set of the points at infinity is called, depending on the dimension of the space, the line at infinity, the plane at infinity or the hyperplane at infinity, in all cases a projective space of one less dimension.

  4. List of Mayday episodes - Wikipedia

    en.wikipedia.org/wiki/List_of_Mayday_episodes

    As of 12 January 2025, 276 episodes of Mayday have aired. [ n 1 ] This includes five Science of Disaster specials, each examining multiple crashes with similar causes. For broadcasters that do not use the series name Mayday , three Season 3 episodes were labelled as Crash Scene Investigation spin-offs, examining marine or rail disasters.

  5. Hyperplane at infinity - Wikipedia

    en.wikipedia.org/wiki/Hyperplane_at_infinity

    In the projective space, each projective subspace of dimension k intersects the ideal hyperplane in a projective subspace "at infinity" whose dimension is k − 1. A pair of non- parallel affine hyperplanes intersect at an affine subspace of dimension n − 2 , but a parallel pair of affine hyperplanes intersect at a projective subspace of the ...

  6. Riemann sphere - Wikipedia

    en.wikipedia.org/wiki/Riemann_sphere

    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 .

  7. Modular group - Wikipedia

    en.wikipedia.org/wiki/Modular_group

    Two points in the upper half-plane give isomorphic elliptic curves if and only if they are related by a transformation in the modular group. Thus, the quotient of the upper half-plane by the action of the modular group is the so-called moduli space of elliptic curves: a space whose points describe isomorphism classes of elliptic curves.

  8. Projectively extended real line - Wikipedia

    en.wikipedia.org/wiki/Projectively_extended_real...

    The projectively extended real line can be visualized as the real number line wrapped around a circle (by some form of stereographic projection) with an additional point at infinity. In real analysis , the projectively extended real line (also called the one-point compactification of the real line ), is the extension of the set of the real ...

    MH370: The Plane That Disappeared is a British docuseries released on Netflix and directed by Louise Malkinson about the 2014 disappearance of Malaysia Airlines Flight 370. [ 1 ] The documentary aims to present three contradictory but well documented scenarios of the plane's disappearance.
