It should remind you of angular momentum, who's vector direction is in the direction perpendicular to the plane of rotation. ( 10 votes) Upvote Downvote Flag Akshat Jha 6 years ago Around 4:00

The curl of the gradient of any continuously twice-differentiable scalar field (i.e., differentiability class ) is always the zero vector : It can be easily proved by expressing in a Cartesian coordinate system with Schwarz's theorem (also called Clairaut's theorem on equality of mixed partials).
