Sectornoun

a mathematical instrument consisting of two arms hinged at one end and marked with sines, tangents, etc. for making diagrams.

Spherenoun

(mathematics) A regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about its diameter .

Spherenoun

A spherical physical object; a globe or ball.

Spherenoun

Spherenoun

Any of the concentric hollow transparent globes formerly believed to rotate around the Earth, and which carried the heavenly bodies; there were originally believed to be eight, and later nine and ten; friction between them was thought to cause a harmonious sound (the music of the spheres).

Spherenoun

Sphereverb

(transitive) To place in a sphere, or among the spheres; to ensphere.

Sphereverb

(transitive) To make round or spherical; to perfect.

Spherenoun

A body or space contained under a single surface, which in every part is equally distant from a point within called its center.

Spherenoun

Hence, any globe or globular body, especially a celestial one, as the sun, a planet, or the earth.

Spherenoun

The apparent surface of the heavens, which is assumed to be spherical and everywhere equally distant, in which the heavenly bodies appear to have their places, and on which the various astronomical circles, as of right ascension and declination, the equator, ecliptic, etc., are conceived to be drawn; an ideal geometrical sphere, with the astronomical and geographical circles in their proper positions on it.

Spherenoun

The extension of a general conception, or the totality of the individuals or species to which it may be applied.

Sphere

A sphere (from Greek σφαῖρα—sphaira, ) is a geometrical object in three-dimensional space that is the surface of a ball (viz., analogous to the circular objects in two dimensions, where a circumscribes its ). Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.
