Is Newton’s constant a conventional unit?
I don’t understand this: If Newton’s force has been proved to be unphysical and non-existent by physicists themselves why are we still bound by 18th century derivations involving force? The only answer to this can be that Newton’s occult and non-existent force has pedagogical value because it is simpler to teach than General Relativity. But does this justify experimental observation of the Newtonian occult and non-existent force in class with a Cavendish pendulum? If physicists proved Newtonian force to be unphysical how do they measure it in a physical experiment? Can you measure an unphysical force that exists only pedagogically in a physical experiment? I say no. To me this suggests a bureaucratic habit. Schools continue to teach the Cavendish lab because they always have. This cannot be allowed to happen in an experimental science such as physics. The other pedagogical advantage is, as physicists put it, “Newton’s laws and Newton’s mechanics work well in the solar system and in sys
