In
mathematics and
physics, the
dimension of a
space or
object is informally defined as the minimum number of
coordinates needed to specify each
point within it.
[1][2] Thus a
line has a dimension of one because only one coordinate is needed to specify a point on it. A
surface such as a
plane or the surface of a
cylinder or
sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its
latitude and its
longitude). The inside of a
cube, a cylinder or a sphere is three-dimensional because three co-ordinates are needed to locate a point within these spaces......
