**The direction in the 4D Space-Time continuum is lost in
the scalar product.**

** **

**This equation describes only Bosons – for example:
photons **

**(It is the wave equation obtained from Maxwell’s
equations of electrodynamics.)**

**The expansion separates space from time in the 4D
Space-Time continuum.**

** **

**This allows a coordinate separation among radial,
angular, and time coordinates**

** **

**
****Y(r,****q,****f,t) =
R(r)Y(****q,****f)T(t)**

** **

**This permits the spin to be treated as an angular
coordinate, and combined with the spatial rotations**

** **

** Y(****q,****f) ****® Y(****q,****f)****c(spin)**

** **

And here the orbital and spin angular momentum of many electrons can be combined.

__ __

**Here the 4D Space-Time continuum causes spin to be an
intrinsic dynamic quantity, associated with its 4D nature (and NOT angular
variable).**

** **

**It is bound individually to the electron (up/down) and
positron (up/down) solutions.**

** **

**Thus, the result is relativistically correct for a single
electron charge-coupled to a nucleus.**

** **

**Virtual photon exchange with all other electrons in the
universe are neglected.**

** **

**It includes only the connection of the spin-own-orbit
interaction, and cannot include spin-other-orbit or orbit-other-orbit interactions.
