Sir Isaac Newton, an astronomer, mathematician, and a scientist is described to be "one of the greatest names in history of human thought." Newton, born on December 25, 1642 in Woolsthorpe, Lincolnshire, England, was interested in creating mechanic toys as a young boy. He even invented an impressive, small windmill, which would grind wheat and corn, at a young age. Newton explored beyond the secrets of light and color, found gravity, and even discovered a new form of mathematics, called calculus. It was Newton that had explained why a rock is heavier than a pebble, and how earth's gravity could hold the moon in its orbit. .
Sir Isaac Newton's greatest contribution to science was his discovery of the theory of gravitation and its importance. When Newton saw an apple falling from a tree, he realized that there had to be an exerting force that was pulling the apple down towards the earth. This force, which Newton called gravity, also pulls and holds the moon in the orbit, preventing it from floating away. Another theory Newton discovered is the theory of motion. This theory states that an object in motion will stay in motion until someone or something stops it or slows the object down. Sir Isaac Newton also explained the law of friction, that without friction an object can be in motion forever. Newton's contributions doesn't stop with gravity and friction. Newton also explained the secrets of light and color, stating that sunlight is a mixture of the lights of all colors. Once Newton darkened his room, to see a tiny whole that had a beam of light coming in. The light resulted in multi colors, in which is called a color spectrum, a rainbow of colors. This caused him to construct a new telescope that involves a reflecting mirror instead of lenses. Through his new telescope, he amazingly saw the satellites of Jupiter. Newton made all three impressive discoveries within 18 months! .
Besides Newton's theory of gravity, laws of motion, and his discovery of the amazing rainbow colors, Newton made another remarkable discovery called Calculus.
