Oval

An oval (from Latin ovum, ) is a closed curve in a plane which resembles the outline of an egg. The term is not very specific, but in some areas (projective geometry, technical drawing, etc.) it is given a more precise definition, which may include either one or two axes of symmetry of an ellipse.

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.

Spherenoun

Circuit or range of action, knowledge, or influence; compass; province; employment; place of existence.

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.
