In this paper we show how Dirac, in 1947, anticipated the Bohm ap- proach using an argument based on what is now called the Heisenberg picture. From a detailed examination of these ideas, we show that the role played by the Dirac standard ket is equivalent to the introduction and use of the idempotent in the orthogonal and symplectic Clifford algebras.

This formalism is then used to show that the so-called ‘Bohm trajectories’ are the average of an ensemble of individual stochastic Feynman paths. Since the Bohm approach can be simply reduced to classical mechanics, the algebraic formalism presented here provides a natural way to relate quantum mechanics to classical mechanics with- out the need for decoherence. We show that this approach suggests an underlying fractal space-time of the type discussed by Nottale.
