The Unity of Light and Electromagnetism

Your entire reality is held together by just four lines of math. It is actually wild

when you think about it. James Clerk Maxwell realized that electricity and magnetism aren't

separate things, but actually the same force dancing together. He proved that a

changing electric field creates a magnetic one, and a changing magnetic field creates electricity.

This creates a loop, a self-sustaining wave that ripples through space. When you calculate

the speed of that wave using his math, you get the exact speed of light. So basically,

light is just electricity and magnetism vibing together, and without these equations,

your phone wouldn't exist.
