Newton kindles the juvenile imagination when he relates the tenacious
symphony of the spheres. But when this same mass in consideration
is quasi-infinite in the context, that looks more like an article of
faith provided by an educator: the tender wheels of the student's
traction falter at the concept, do they not? Better to ask the
young to imagine what they can imagine.
A water jet impinging upon a fixed pelton wheel does not in fact
cause some contra-rotation of the Earth mass - no indeed. The force
is reacted much, MUCH closer to home. So teachers who talk of the
Earth moving, are in the position of discussing Angels Dancing Upon
Pin Heads - and I disapprove the dishonesty of it.
