  A quantitatively verifiable expression for the Gravitational Constant is
derived in terms of quantum mechanical quantities. This derivation appears to
be possible by selecting a suitable physical process in which the
transformation of the equation of motion into a quantum mechanical wave
equation can be obtained by Einstein's geodesic approach. The selected process
is the pi-meson, modeled as the one-body equivalent of a two-body quantum
mechanical oscillator in which the vibrating mass is modeled as the result of
the two energy fluxes from the quark and the antiquark. The quantum mechanical
formula for the Gravitational Constant appears to show a quantitatively
verifiable relationship with the Higgs boson as conceived in the Standard
Model.
