sphere

subject fact

sphere has dimensions 3 2001-09-27 09:32:37.0
has definition The outer surface of a ball. The surface of a familiar three-dimensional ball has two dimensions (which can be labeled by two numbers such as "latitude" and "longitude," as on the surface of the earth). The concept of a sphere, though, applies more generally to balls and hence their surfaces, in any number of dimensions. A one-dimensional sphere is a fancy name for a circle; a zero-dimensional sphere is two points (as explained in the text). A three-dimensional sphere is harder to picture; it is the surface of a four-dimensional ball. has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:32:37.0

Kinds of sphere :

celestial sphere (3 facts) - An imaginary sphere of arbitrary radius upon which celestial bodies may be considered to be located. As circumstances require, the celestial sphere may be centered at the observer, at the Earth's center or at any other location.
