How much would you give, to be able to go back in time and meet Isaac Newton, and let him describe his physics to you. And then to be able to quaintly explain relativity to him. -_-

"That's all very interesting, Mr. Newton. But did you know that it is actually the apple which is standing still, and you being forced into it?" (-_q)
Beliefs in a nutshell:
- The Ends never justify the Means.
- Objectivity is secondary to subjectivity.
- The War on Drugs is the worst policy in the U.S.
- Most people worship technology as a religion.
- Computers will never become sentient.

The way Einstein described it originally would probably serve to demonstrate it pretty well to him, assuming he could get the whole "train" thing.

Sorry that was the scotch talking, I didn't mean to say the apple was standing still lol. I should say, the force is on you and not the apple ;)

Newton quite openly admitted that he did not understand how gravity worked and that his laws only described it very accurately. He would have been thrilled with general relativity.

It is interesting to ponder what he would have done with 21st Century knowledge a full four centuries early. What world would await you when you returned to modern day?

With his concept of absolute and relative space and his comments on them, Newton appears to have second-guessed Einstein to some extent. I think he either decided against furthering those ideas or forgot about it. Good for Einstein he did too.

I think we can forget about a man like Newton forgetting about relativity, my friend ;)

If Newton was beginning to realize relativity, it's very likely he realized how absolutely ridiculous it would have sounded to the people of the day. At any rate, I don't think there was enough data at the time to really measure relativistic effects.

Newton not only described gravity, he also developed the math necessary to describe it more fully than just the fall of an apple. Most of us learned Newton's Law of Gravity with its product of masses and inverse square law, but how many of us have the math necessary to derive the laws of planetary motion in elliptical orbits from that basic equation?

I agree. I am in awe of Newton's work. As you say he developed calculus and many other tools that we take for granted now. The math needed to prove elliptic orbits is very involved and to be honest I would have to go back to the textbooks for help. I believe Newton's initial proof was a rather elegant geometry based piece of work from which he extrapolated back from Keplar's Laws to his own now famous inverse square law. I find it interesting that Newton used geometry and that it was geometry that led Einstein to his general relativity theory.
