His major accomplishments in the fields of math, physics, and optics are well known. For his accomplishment in math, he is considered to have invented Calculus. Although his works of Calculus were not published before a man name Leibniz, but Newton is still considered as the inventor of Calculus. Newton discovered the Binomial Theorem, which was used for fractional powers (Weinstein 2). He also developed many analytical ways to solve many problems such as: find areas, tangents, lengths of curves, and the maxima and minima of functions (O"Connor & Robertson 3). As mathematician, Newton and Leibniz invented differential calculus. He also calculated a formula for finding the velocity of sound in a gas, which was later corrected by Laplace (Chew 1). Newton made many contributions to the field of physics. He developed the three laws of motion. The first was the law of inertia. This law stated that objects in motion would continue to move in that direction at a constant velocity unless an outside force acts upon it. His second law stated that for every action there is an equal and opposite reaction. Finally, his third law sate that forces causes masses to accelerate. As the acceleration increases the force increases as well. They are directly proportion to each other. Newton is considered to come up with the theory of universal gravitation. This is not totally true, but he did contribute to it. Newton made a huge impact on theoretical astronomy. He defined the laws of motion and universal gravitation, which he used to predict precisely the motions of stars, and the planets around the sun. Using his discoveries in optics Newton constructed the first reflecting telescope (Chew1). Other accomplishments that Newton made in the physics field was discovering the law about centrifugal force on body that is moving in a circular path. He did not totally understand the idea of circular motion. In 1666 Newton's main idea was that the Earth's gravity influenced the moon, therefore counterbalancing it's centrifugal force.
