  The Einstein-Podolski-Rosen paradox highlights several strange properties of
quantum mechanics including the super position of states, the non locality and
its limitation to determine an experiment only statistically. Here, this well
known paradox is revisited theoretically for a pair of spin 1/2 systems in a
singlet state under the assumption that in classical physics time evolves in
discrete time steps Deltat while in quantum mechanics the individual spin
system(s) evolve(s) between the eigenstates harmonically with a period of 4
Deltat. It is further assumed that time is a single variable, that the quantum
mechanics time evolution and the classical physics discrete time evolution are
coherent to each other, and that the precision of the start of the experiment
and of the measurement time point are much less than Deltat. Under these
conditions, it is demonstrated for a spin 1/2 system that the fast oscillation
between the eigen states spin up and spin down reproduces the expected outcome
of a single measurement as well as ensemble measurements without the need of
postulating a simultaneous superposition of the spin system in its quantum
state. When this concept is applied to a spin 1/2 system pair in a singlet
state it is shown that no entanglement between the two spins is necessary to
describe the system resolving the Einstein-Podolski-Rosen paradox.
