Didn't Heaviside condense Maxwell's nine (or more?) original equations down to the four we know and use today?

Didn'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.
