  Maintaining the position that the wave function $\psi$ provides a complete
description of state, the traditional formalism of quantum mechanics is
augmented by introducing continuous trajectories for particles which are sample
paths of a stochastic process determined (including the underlying probability
space) by $\psi$. In the resulting formalism, problems relating to measurements
and objective reality are solved as in Bohmian mechanics (without sharing its
weak points). The pitfalls of Nelson's stochastic mechanics are also avoided.
