Vcubingx does “Green’s Theorem, Explained Visually”. It's a great animation idea.
I don’t recall encountering line integrals when I did my MA in Mathematics at the University of Kansas, 1966-1968.
But the concepts of line integral and curl definitely fit into science fiction, and even explaining how some space megastructures would work (maybe even O’Neill Cylinders).
So this little video actually helps with my screenplay. A nice accidental find on a Saturday night after a day on the road.
