en.wikipedia.org/wiki/Divergence

In vector calculus, divergence is a vector operator that produces a signed scalar
field giving the quantity of a vector field's source at each point. More technically ...

In this section we are going to introduce a couple of new concepts, the curl and
the divergence of a vector. Let's start with the curl. Given the vector field the curl ...

Both the divergence and curl are vector operators whose properties are revealed
by viewing a vector field as the flow of a fluid or gas. Here we focus on the ...

The physical significance of the divergence of a vector field is the rate at which "
density" exits a given region of space. The definition of the divergence therefore ...

(a) We define the divergence of a vector field F, written div F or ∇ · F, as the dot
product of ... In fact, we can identify conservative vector fields with the curl:.

The divergence is a scalar function of a vector field. The divergence theorem is
an important mathematical tool in electricity and magnetism.

Basically, divergence has to do with how a vector field changes its magnitude in
the neighborhood of a point, and curl has to do with how its direction changes.

Divergence measures the change in density of a fluid flowing according to a
given vector field.
