Natural way to think of a curl of curl is to think of the infinitesimal rotation in that rotation itself. Just as a second derivative describes the rate of rate of change, so the curl of curl describes the way the rotation rotates at each point in space.

WebJan 17, 2015 · A tricky way is to use Grassmann identity a × (b × c) = (a ⋅ c)b − (a ⋅ b)c = b(a ⋅ c) − (a ⋅ b)c but it's not a proof, just a way to remember it ! And thus, if you set a = b = ∇ and c = A, you'll get the result. – idm.
