A heuristic description of the spin-rotation-gravity coupling is presented and the implications of the corresponding gravitomagnetic Stern-Gerlach force are briefly mentioned. It is shown, within the framework of linearized general relativity, that the gravitomagnetic Stern-Gerlach force reduces in the appropriate correspondence limit to the classical Mathisson spin-curvature force.
Keywords: spin-gravity coupling; spin-vorticity coupling.
