The Limits of Quantum Mechanics in the Light of the Genuine   Fortuitousness Principle
  To test the limits of quantum mechanics, a proposal for an experiment on protons is suggested. The spin component of proton is measured very rapidly in sequential measurements. The reason for this experiment is derived from the genuine fortuitousness principle, (A. Bohr, B. R. Mottelson, and O. Ulfbeck, (2004)).
