- Gradient - Khan Academy (by Grant Sanderson of 3Blue1Brown) (Article) — Explains why the del symbol is treated as a vector of partial-derivative operators, and why the gradient points along steepest increase. Start here before divergence and curl.
- Physical Interpretation of grad, curl, div - University of Alberta (Article) — A concise, exam-friendly writeup of what each operator physically means, including solenoidal and irrotational fields. Good source for the 'physical significance' part of the question, which most stu…
- Partial derivatives, gradient, divergence, curl - Khan Academy (Video) — Sequential videos working through the actual computation of grad, div and curl. Watch these if you can state the definitions but cannot compute them quickly.
