Bohmian Mechanics

Bohmian mechanics is the new mechanics for point particles. In the equations for Bohmian mechanics there are parameters m₁,…,m_N which we shall call masses. We do so because in certain physical situations the particles will move along Newtonian trajectories and then these masses are Newtonian masses, and there is no point in inventing new names here. Although the theory is not at all Newtonian, it is nevertheless close in spirit to the Hamilton–Jacobi theory and an implementation of Born’s guiding idea. The theory is in fact the minimal non-trivial Galilean theory of particles which move. We already gave the defining ingredients in the last chapter. Now we shall spell things out in detail.
