divergence n
1. the act of moving away in different direction from a common point; "an angle is formed by the divergence of two straight lines" [syn: divergency]
2. a variation that deviates from the standard or norm; "the deviation from the mean" [syn: deviation, departure, difference]
3. an infinite series that has no limit [syn: divergency] [ant: convergence, convergence]
4. a difference between conflicting facts or claims or opinions; "a growing divergence of opinion" [syn: discrepancy, disagreement, variance]

Divergence \Di*ver"gence\, Divergency \Di*ver"gen*cy\, n. [Cf. F. divergence.]
1. A receding from each other in moving from a common center; the state of being divergent; as, an angle is made by the divergence of straight lines. Rays come to the eye in a state of divergency. --??????.

In vector calculus, divergence is a vector operator that measures the magnitude of a vector field's source or sink at a given point, in terms of a signed scalar. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point. For example, consider air as it is heated or cooled. The relevant vector field for this example is the velocity of the moving air at a point. If air is heated in a region it will expand in all directions such that the velocity field points outward from that region. Therefore the divergence of the velocity field in that region would have a positive value, as the region is a source. If the air cools and contracts, the divergence is negative and the region is called a sink.
