  The gravitational inverse square law is microscopic approximation. I suggest
that it should be modified for elementary particles to use the
surface-to-surface separation of the particles rather than the center-to-center
separations. For small particles at macroscopic separations, the ratio between
the center-to-center distance D and the surface-to-surface distance d, D/d,
approaches unity. At microscopic separations, this ratio grows very large. Here
I apply this ratio to several microscopic situations and derive the nuclear
coupling constants. I will then present a model of a gluon/graviton
transformation to justify my surface originating modification.
