of quantum mechanics wasn't a mystery anymore. In Arthur’s equations,
As the sun dipped below the horizon, Arthur’s chalk began to fly. He realized that by simply adding these different types of objects together—scalars, vectors, and bivectors—he created a . This was the "Geometric Algebra" Clifford had dreamed of. Suddenly, the "imaginary" Geometric Algebra for Physicists
To the outside world, Arthur was a success. He understood the language of the universe. But to Arthur, that language felt like a broken mosaic. To describe a rotating electron, he needed complex numbers. To describe its movement through space, he used vectors. To reconcile it with relativity, he turned to four-vectors and Pauli matrices. of quantum mechanics wasn't a mystery anymore
By dawn, Arthur looked at his chalkboard. It no longer looked like a battlefield of indices. It looked like a map. He realized that for a century, physicists had been like builders trying to describe a house using only the lengths of the boards, ignoring the angles at which they met. Geometric Algebra provided the angles. This was the "Geometric Algebra" Clifford had dreamed of
