  The new dynamical `quantum foam' theory of 3-space is described at the
classical level by a velocity field. This has been repeatedly detected and for
which the dynamical equations are now established. These equations predict
3-space `gravitational wave' effects, and these have been observed, and the
1991 DeWitte data is analysed to reveal the fractal structure of these
`gravitational waves'. This velocity field describes the differential motion of
3-space, and the various equations of physics must be generalised to
incorporate this 3-space dynamics. Here a new generalised Schrodinger equation
is given and analysed. It is shown that from this equation the equivalence
principle may be derived as a quantum effect, and that as well this generalised
Schr\"{o}dinger equation determines the effects of vorticity of the 3-space
flow, or `frame-dragging', on matter, and which is being studied by the Gravity
Probe B (GP-B) satellite gyroscope experiment.
