Divergence

Intuitive

Divergence (div) is “flux density”—the amount of flux entering or leaving a point. Think of it as the rate of flux expansion (positive divergence) or flux contraction (negative divergence). If you measure flux in bananas (and c’mon, who doesn’t?), a positive divergence means your location is a source of bananas. You’ve hit the Donkey Kong jackpot.

Vector Calculus: Understanding Divergence by Kalid Azad

Concrete

Abstract

The motto in this section is: the higher the level of abstraction, the better.

Why is it interesting?

The divergence is a crucial tool, for example, in electrodynamics. This can be seen immediately because the fundamental equations of electrodynamics (called Maxwell equations) contain the divergence of the electric and magnetic fields.
