Isaac Newton Stood Quotations

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.

I understood. I have understood. I do understand.

If I saw further than other men, it was because I stood on the shoulders of giants.
