1. 1.divergence (degree to which two or more things diverge)
2. 2.divergence (evolutionary changes leading to increasing differences between closely related species living under different conditions)
3. 3.convergence (increasingly strong differentiation and separation of new cultures)
4. 4.divergence (vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point)
