I learned this in undergrad calc 1 as the Heaviside cover-up method [1], named after Oliver Heaviside.
Heaviside was a remarkably productive scientist [2], contributing to a range of topics from vector calculus to electromagnetic theory.

- tigerlily 8y agoDidn't Heaviside condense Maxwell's nine (or more?) original equations down to the four we know and use today?
- ekun 8y agoIn the wiki linked, that is in fact his first-listed innovation ... he condensed 20 equations into 4 using vector calculus.
- antidesitter 8y agoAnd those equations can be condensed into a single manifestly covariant equation: □A = J where □ is the d'Alembertian, A is the 4-potential, and J is the 4-current.
