101 Amazing Isaac Newton Quotes on Education and Life

Isaac Newton was born on January 4, 1643 in Woolsthorpe, England.

He was one of the most influential scientists in history, renowned for defining the three laws of motion and universal gravitation.

Albert Einstein himself acknowledged Newton as the smartest person to have ever lived.

Newton’s noteworthy contributions include the development of calculus, key breakthroughs in optics and the invention of the reflecting telescope.

He spent a significant part of his life at Cambridge, both as a mathematics professor and a fellow of the Royal Society.
