? (I don’t see to what you allude here). Physical refer to measurable numbers, sharable between different observers. > If you take Dr. Johnson's view, you can't kick it and have it kick back.

But you can repeat it again and again, and share the distribution, and develop a precise theory. Indeed, that is Quantum Mechanics. Even sending just one particle; we can predict with certainty that the particle will not act in some region of the screen, and that is a kicking back of the fact that we have to take account the wave structure integrally.
