Curl measures how much a vector field is "spinning". A bit of a pain to calculate, but could come in handy when we work with Stokes' and Greens' theorems later on.

Curl warmup, fluid rotation in two dimensions

Curl measures the rotation in a fluid flowing along a vector field. Formally, curl only applies to three dimensions, but here we cover the concept in two dimensions to warmup.
