A classical ontology for quantum phenomena
  Quantum mechanics states that a particle emitted at point (x_1,t_1) and detected at point (x_2,t_2) does not travel along a definite path between the two points. This conclusion arises essentially from the analysis of the two-slit experiment, which implicitly assumes (as in the demonstration of the EPR paradox) that a property we will call Independence Property holds. This paper shows that this assumption is not indispensable. Abandoning the assumption allows to develop an ontology where particle motion is described by classical paths and quantum phenomena are interpreted as a manifestation of a contingent law, i.e., of a law deriving from the boundary conditions of the universe, such as the second law of thermodynamics. The paper also proposes an equation having a typical quantum-like structure to represent the contingent laws of the universe.
