From 20 Equations to 4: The Discovery of Maxwell's Equations

I explore the fascinating journey of how James Clerk Maxwell unified electricity and magnetism, building on Michael Faraday's experimental insights. The story reveals how Maxwell's original complex set of 20 equations was later simplified by Oliver Heaviside into the elegant four vector equations we know today, fundamentally changing our understanding of light and the universe.

"Maxwell: 20 equations. Heaviside: no they're actually 4 in vector notation. Space-time algebra: well, actually that's just one single equation."
