Sir Isaac Newton was an English physicist, mathematician, astronomer, natural philosopher, and alchemist, widely known for his contribution to the scientific revolution of the 17th century.

As a child, his mother pulled him out of school as she wanted Newton to become a farmer. As expected, such a bright kid was no fit to be a farmer, and was obviously terrible at it. As a consequence, he was sent back to school to finish his education.

Newton developed the laws of motion and the theory of gravity. He also made discoveries in optics – a theory of colors – stating that the white light is a composite of all colors of the spectrum. His masterpiece Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) brought him fame in the world of physics. After publishing the book, Newton was knighted and became Sir Isaac Newton.

A lot of his work remained unpublished long after his death, especially studies on alchemy and biblical chronology. However, we have enough access to his work nowadays and, of course, to his words of wisdom. So here are 17 Isaac Newton quotes to help you develop your inner curiosity.
