Abstract: It is argued that a realistic interpretation of quantum mechanics is possible and useful. Current interpretations, from ?Copenhagen? to many worlds? are critically revisited. The difficulties for intuitive models of quantum physics are pointed out and possible solutions proposed. In particular the existence of discrete states, the quantum jumps, the alleged lack of objective properties, measurement theory, the probabilistic character of quantum physics, the wave?particle duality and the Bell inequalities are analyzed. The sketch of a realistic picture of the quantum world is presented. It rests upon the assumption that quantum mechanics is a stochastic theory whose randomness derives from the existence of vacuum fields. They correspond to the vacuum fluctuations of quantum field theory, but taken as real rather than virtual.
