This was great, I felt like I was reading a mathematical soap opera. That is so bizarre how much drama was happening in the world of the sciences. It kind of made me wonder, they could not have been the only two other people in the world at that time that had been exploring and learning/inventing calculous? (That is not a question for you, just one I am pondering on my own.) I certainly think that remembering where things came from, especially something that effects our lives so regularly, is important to remember. Therefore, I do believe Philosophiae Naturalis Principia Mathematica and Newton's life in general ought to be preserved. Do you think Newton's followers were correct in thinking, "if Newton’s rules applied to nature then our actions could be determined like any other event in nature"?
