We’re told how mysterious spinors are, they are not observable, to dymystefy spinor, I’d like to compare Dirac spinor to Spin-0 and spin-1, these two are actually not spinors at all, but the name is sort of misguiding.

The key difference is how they transform! Spinor transform is not a coordinate change — it’s a change of representation basis.

Further, the key is Lorentz boosts is confined in a circle, it’s hyperbolic, extending limitless,

Scalars and vectors live in spacetime. Spinors live above spacetime, in representation space.
