Dear Friends:

I have added sections 12, 13 and 14 to the Kaluza-Klein paper which I
have earlier posted. These sections examine the relationship between
the electrodynamics potentials and the gravitational potentials, and
connect to QED.

Most significantly, these three sections not only connect to the QED
Lagrangian, but, they show how the familiar QED Lagrangian density

L = -(1/4) F dot F - J dot A

emerges *in the linear approximation* of 5-dimensional Kaluza-Klein
gravitational theory.

Then, we go in the opposite direction, to show the QED Lagrangian
density / action for *non-linear* theory, based on the full-blown
apparatus of gravitational theory. You may view this at:

Again, focus on sections 12, 13 and 14.

Looking for constructive feedback.

Thanks,

Jay.
