Dec 30 accepted Do stars appear to move with uniform motion? Dec 30 comment Do stars appear to move with uniform motion? I'm not sure what you mean by the stars rising and setting :-P Dec 29 asked Do stars appear to move with uniform motion? Sep 2 accepted How Did Newton's Second Law Get Its Definition? Aug 30 awarded Commentator Aug 30 comment How Did Newton's Second Law Get Its Definition? Thanks so much Ron, really. This helped a lot :] I have to ask, though; could you recommend any reads/books for me? (now that you have a general sense of the history that I'm interested in) I don't mind going as far back as Archimedes if I have to haha. The journey of scientific discovery and thought from Archimedes' Law of the Lever to Newton's Laws fascinates me and I would love to rectify any remaining curiosities on the matter. Aug 27 comment How Did Newton's Second Law Get Its Definition? I should've figured as much, I'd always read that Newton acted as the primary figure in the mathematical formulation of these concepts but I never knew how. Another thing that I was curious about was how Newton stated the 2nd Law as an axiom. I haven't fully read the Principia but wouldn't that mean that he's stating it as fact without proof? Or I guess you could surmise that he did so because it was so self-evident at that time, as you said. Aug 26 comment How Did Newton's Second Law Get Its Definition? I've been shortchanging Galileo and Newton this whole time :-\ I had no idea that all this was known prior to Newton; university physics texts really like portraying Newton as the one who'd made these discoveries. But I think another thing that was confusing me was how the concept of weight was viewed during Galileo's time. I generally assumed that at that time weight wasn't viewed as a force but just some property of objects that compared their sizes or amounts. Aug 24 awarded Supporter Aug 24 comment How Did Newton's Second Law Get Its Definition? So in other words, Newton's statement $\frac{\Delta p}{\Delta t} \propto F$ was "derived" from Galileo's treatment? Aug 23 asked How Did Newton's Second Law Get Its Definition? Aug 4 comment Combining Proportions to get Newton's Law of Universal Gravitation I'm definitely not reading this correctly :[ I think I understand what you mean by the last section though, where you explain why the masses are multiplied with one another. I'm not sure if what you wrote here though explains how the inverse square law and the quantity of masses ($m_1m_2$) were put together.

Thanks again for the quick response. I don't think this is quite what I was looking for though, unless I'm not reading this properly. I was just curious about the math that brought these separate parts together. But regardless, thanks for clarifying how this concept was conceived! :] Jul 25 revised Combining Proportions to get Newton's Law of Universal Gravitation deleted 10 characters in body Jul 24 asked Combining Proportions to get Newton's Law of Universal Gravitation Jun 26 comment Euclidean Geometry in Classical Thought - Realization or Representation?
