n -sphere. n. -sphere. 2-sphere wireframe as an orthogonal projection. Just as a stereographic projection can project a sphere's surface to a plane, it can also project a 3 -sphere into 3 -space. This image shows three coordinate directions projected to 3 -space: parallels (red), meridians (blue), and hypermeridians (green).
In geometry, a spherical sector, [ 1] also known as a spherical cone, [ 2] is a portion of a sphere or of a ball defined by a conical boundary with apex at the center of the sphere. It can be described as the union of a spherical cap and the cone formed by the center of the sphere and the base of the cap. It is the three-dimensional analogue of ...
In a small triangle on the face of the earth, the sum of the angles is only slightly more than 180 degrees. A sphere with a spherical triangle on it. Spherical geometry or spherics (from Ancient Greek σφαιρικά) is the geometry of the two- dimensional surface of a sphere [ a] or the n -dimensional surface of higher dimensional spheres .

Visualization of the whole observable universe.The inner blue ring indicates the approximate size of the Hubble volume. In cosmology, a Hubble volume (named for the astronomer Edwin Hubble) or Hubble sphere, Hubble bubble, subluminal sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an observer beyond which objects recede from that ...

Circumscribed sphere. In geometry, a circumscribed sphere of a polyhedron is a sphere that contains the polyhedron and touches each of the polyhedron's vertices. [1] The word circumsphere is sometimes used to mean the same thing, by analogy with the term circumcircle. [2] As in the case of two-dimensional circumscribed circles (circumcircles ...
