Issac Newtib Essay, Research Paper

After his discovery, Newton was accepted into the Royal Society after sending one of his telescopes to them in 1671. He wrote to one of the members stating that he made discoveries that led him to the building of the telescope. Newton sent a paper with experiments and facts that white light was actually a mixture of colors. The Society didn’t accept this theory and he was stuck between a rock and a hard place. He got into many arguments and had to prove his theory. Newton continued with his work even though he was ridiculed. He kept his work confidential until he published his book Opticks in 1704 on his theory of light. He talked about sunlight when passed through a prism; different blends of light rays separate from the sunlight. This led him to the building of his reflecting telescope.Newton’s best work was in the fields of Gravity, Astronomy, and Motion. Everyone has probably heard of the story of New and the apple. Newton was sitting in a forest in Woolsthrope and he saw an apple fall to the ground. This led him to believe that there is some kind of pull or force on the earth. He soon found out that the same pull that dropped the apple is the same that pull keeps the moon in orbit. He showed this theory by tying an object to a string and spinning it around. It proved why the moon and the other planets are in space. With this and a visit from Edmund Halley it possible for Newton to publish another book, The Mathematical Principles of Natural Philosophy, or Principia. This book was talked about everywhere. It was a sensation, the talk of the town. The book showed how forces acted upon his basic laws of motion. Newton’s three laws of motion are:1) The body will stay at rest (if it is not already moving) or will continue to move at the same speed and in straight line (if it is already moving) unless an outside force acts upon it (Inertia). 2) A moving body moves faster, or accelerates, when a force acts on it. It accelerates in the direction of the force, and the amount of acceleration depends on the size of the force and the mass of the object. (An empty shopping cart will be easier than a full one)3) Forces always act in pairs. If you push or pull an object, it will push or pull you in return and with equal force (Action and Reaction). “The force that body A exerts on body B is always equal and opposites to the force that body B exerts on body A.” All of these things and explanations to them are in the book, Principia. This book started the principles of modern science.Newton’s next step in life was teaching in Trinity College. He was then elected to the Parliament for Cambridge. This happened when Newton made an attempt to stop James II in 1689. During his time he didn’t do much in the Parliament. In 1695, Newton became a Warden of the Mint in London. Even though he was a Warden he still did his duties at Cambridge. Then in 1703 Newton became President of the Royal Society and for the rest of his life.Isaac Newton died on the morning of March 20, 1727, a life span of about eighty-five years. He made many contributions like inventing modern science and calculus. I think he was a brilliant man of his time and deserves a bit more credit for his work. This concludes my report on Sir Isaac Newton. BibliographyMctavish, Douglas. Isaac Newton. New York, NY: The Bookwrite Press, 1990. Moore, Patrick. Isaac Newton.
