Some passages reveal a physical interpretation of the Quantum Mechanics which anticipates of several years the Feynman approach in terms of path integrals, independently of the underlying mathematical formulation.revtex, 9 pages, 2 figures; a contribution in the centenary of the birth of Ettore MajoranaHistory and Philosophy of PhysicsHigh Energy Physics - PhenomenologyHigh Energy Physics - TheoryPhysics EducationPopular Physicstext
