"How to turn the complex mathematics of vector calculus
into simple pictures":
Joon-Hwi Kim at Seoul National University in
South Korea and a couple of colleagues who have come up with a similar
innovation for vector calculus—a graphics-based shorthand for one of the
most common and powerful mathematical tools in science. “We anticipate
that graphical vector calculus will lower the barriers in learning and
practicing vector calculus, as Feynman diagrams did in quantum field
theory,” they say.
I've only skimmed the paper, and I'm not yet convinced of the ultimate benefit. But others can read
the original paper and decide for themselves
