Isaac Newton

An object that is at rest will tend to stay at rest. An object that is in motion will tend to stay in motion.

Isaac Newton

As a blind man has no idea of colors, so have we no idea of the manner by which the all-wise God perceives and understands all things.

Isaac Newton

Errors are not in the art but in the artificers.

Isaac Newton

Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.

Isaac Newton

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances.

Isaac Newton

Gravity explains the motions of the planets, but it cannot explain who set the planets in motion.

Isaac Newton

He who thinks half-heartedly will not believe in God; but he who really thinks has to believe in God.

Isaac Newton

I can calculate the motion of heavenly bodies, but not the madness of people.

Isaac Newton

I understood. I have understood. I do understand.

Isaac Newton

If I had stayed for other people to make my tools and things for me, I had never made anything.

Isaac Newton
