  This paper critically considers the main interpretations of the wave function
and offers an interpretation in which wave function is a consequence of
subquantum processes taking place at the level of the organization of matter
which underlies the phenomena described by quantum mechanics. We show that this
interpretation provides a common ground to explain problematic issues of
quantum theory (wave function collapse, electrons passing through two slits,
behavior of electrons within the atom, quantum entanglement). The paper also
shows that entropy is determined by the maximum number of macrosystem states
which appear as the result of subquantum processes.
