Why Does Stuff Happen? Gradients!

Gradients, a form of the del operator, are a way to measure change in field strength across one, two, or even three dimensional space. They come up all over physics: fluid dynamics, conservative forces, electrodynamics, cosmology. They're the reason that anything ever happens.
