His would have had no internal adjustments but if someone had suggested the modern way of providing them, he would not have been impressed. Why? Because he also knew a bit about physics, becoming the world’s greatest authority on it for the next 200 years. An important part of his research produced Newton's laws of motion, which say among other things that objects tend to stay where they are unless something moves them . . . . . . And once something is moving, it keeps going until something stops it or slows it down. So, what does that have to do with modern riflescopes? Well, if you have most of the guts of a scope hinged at one end and held against adjustments at the other end only by a spring, interesting things can happen when you pull the trigger. . . . Then we need to consider Newton's third law of motion and how this is affected by the offsetting effects of scope mounts and stock drop at heel. Given enough recoil, your erector tube may whack against the scope outer, as the rifle rises, and crash back against the screws repeatedly at each shot, risking loss of zero and early breakdown. ‘LIGHT AT THE START OF THE TUNNEL – Are rifle scopes off the rails’ goes into stuff like this in language easier to understand than Isaac's. Later in life Newton became Master of the British Mint - and...
