Is there a Dirac equation for the Proton or Neutron?

To the best of my knowledge, because the Dirac equation explains very well the gyromagnetic ratio of the Electron, it is typically considered to be an equation for the Electron. There seems to be...

Do you know of any non-Euclidean geometries that preserve both the length and the angle upon parallel transport?

For example, Riemann geometry is a non-Euclidean geometry that only preserves the length upon parallel transport. I have come up with a geometry that preserves both the angle and length upon...

Do you think a Unified Field Theory is acheivable on a four dimensional continuum of spacetime?

In this reading, we vigorously demonstrate that all the known forces can be described by a single four vector potential. The theory is a unified theory not of just the four known forces, but of...
