Special thanks to these supporters: http://3b1b.co/divcurl-thanks My work on this topic at Khan Academy: https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives Timestamps 0:00 - Vector fields 2:15 - What is divergence 4:31 - What is curl 5:47 - Maxwell's equations 7:36 - Dynamic systems 10:37 - Explaining the notation 13:28 - No more sponsor messages Correction at 4:55, the narration should say "counterclockwise rotation gives positive curl, clockwise rotation gives negative curl". The diagram is correct, though.
