What “sphere” means
Wiktionary · Wikipediasphere/sfɪə/
- nounA regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about its diameter .
- verbTo place in a sphere, or among the spheres; to ensphere.
A sphere is a surface analogous to the circle, a curve. In solid geometry, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and the distance r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.
