cur·va·ture

 (kûr′və-cho͝or′, -chər)
n.
1. The act of curving or the state of being curved.
2. Mathematics
a. The ratio of the change in the angle of a tangent that moves over a given arc to the length of the arc.
b. The limit of this ratio as the length of the arc approaches zero.
c. The reciprocal of the radius of a circle.
3. Medicine A curving or bending, especially an abnormal one: curvature of the spine.

[Middle English, from Latin curvātūra, from curvātus, past participle of curvāre, to bend, from curvus, curved; see sker- in Indo-European roots.]

curvature

(ˈkɜːvətʃə)
n
1. something curved or a curved part of a thing
2. (Anatomy) any normal or abnormal curving of a bodily part: curvature of the spine.
3. (Mathematics) geometry the change in inclination of a tangent to a curve over unit length of arc. For a circle or sphere it is the reciprocal of the radius. See also radius of curvature, centre of curvature
4. the act of curving or the state or degree of being curved or bent

It is also tempting to ponder, from a purely physical point of view, on the possibility that the intrinsic curvature of space(-time) owes its existence to null (light-like) electromagnetic fields or simply pure radiation fields.
A two-dimensional plane in three-dimensional real space does not have an intrinsic curvature, but when considering a sphere embedded in euclidean real space, we have to take the curvature of this manifold into account.
