If a vector is an arrow, a spinor is something more subtle—like the "inner state" of that arrow.
The classic way to visualize this is the (or Dirac’s Belt): If you rotate an object 360 degrees, it looks the same. Clifford Algebras and Spinors
Dirac needed to find the "square root" of the wave equation. Specifically, he needed a way to linearize the energy-momentum relationship If a vector is an arrow, a spinor
Without realizing it at first, Dirac had rediscovered Clifford Algebra. By solving this mathematical puzzle, he predicted the existence of . 3. What exactly is a Spinor? If a vector is an arrow
