  The use of an infinity of fluctuating paths of least time that are compatible
with the quantum mechanics indeterminacy provides a new interpretation in
geometrical optic of the interference pattern of Young's double slit
experiment, which suggests that the wave behavior of matter and radiation is
dictated by the space-time geodesics. Moreover, the association of a wave
function to each path of least time as a probability amplitude together with an
uncertainty for momentum and position allows to derive the Schrodinger's
equation starting from the geodesic's characteristics. A new insight is
obtained regarding the Van Der Waals torque as well as Casimir
attraction/repulsion mechanism.
