Isaac Newton
1643–1727 · English mathematician and physicist who described gravity and the laws of motion.
Isaac Newton was born on a farm in Lincolnshire, England, a small and sickly baby whose father had died before he was born. He went to Cambridge University, and when plague closed the university in 1665 and 1666 he returned home, where in about two years he began calculus, studied light, and started thinking about gravity; he later told the story of watching an apple fall. Using a prism, he showed that white light is made of all the colors, and he built the first working reflecting telescope. In 1687, encouraged by the astronomer Edmond Halley, he published the Principia, which set out three laws of motion and the law of universal gravitation, showing that the same force that makes an apple fall keeps the Moon in orbit and the planets moving around the Sun. Newton also spent many years studying the Bible, theology and alchemy. He became Warden and then Master of the Royal Mint, president of the Royal Society, and was knighted in 1705. He died in 1727 and was buried in Westminster Abbey.

In their words
“Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon”
“the whiteness of the Sun's Light is compounded of all the primary Colours mix'd in a due Proportion.”
