What does the Isaac Newton Biography have to do with an apple tree?
As you will see in the Isaac Newton Biography, Newton, a mathematician, alchemist, physicist, and astronomer, considered himself to be a natural philosopher. Newton was one of the greatest scientific minds of all time. He took the ideas of earlier scientist and combined them with his own to show how the universe worked. Isaac Newton’s Early YearsNewton's Biography begins on January 4, 1643 in Lincolnshire, England. Newton died on March, 31, 1727 and was buried in Westminster Abbey. He was named after his father who passed away 3 months before his birth. When his mother, Hannah Avscough remarried, young Isaac was sent to live with his maternal grandmother, Margery Ayscough, on a farm. Newton eventually went to The Kings for his education and then onto Trinity College in Cambridge. It was during his college years that Isaac Newton invented what is known today as calculus. Newton and OpticsThe Isaac Newton Biography tells of Newton lecturing on optics. During this time that he shows how a prism can change white light into multicolor light, and a second prism and lens can change the multicolor light back into white light. From this discovery he went on to develop a refracting telescope that is known today as Newtonian telescope. Sir Isaac Newton’s LawsIsaac Newton had three laws to explain how something moved. He used math equations for the explanations. The First Law says that unless something is pushed or pulled, it will continue in a straight line or stay stopped. This is called inertia. The Second Law says that pushing or pulling on something affects how it will react. The Third Law says that if something is pushed or pulled it will push or pull in the opposite way. The Laws were not change for the next two hundred years. It was his writing of these Laws that Sir Isaac Newton developed his theory of gravity.Newton and the apple tree are a myth, but he used an apple and calculated an equation for dropping it. He then turned his sights on the Moon. He realized the same equation he had used with the apple still applied with the Moon and the Earth. Newton didn’t prove there was gravity, but that it applied to the entire universe. He proved through his calculations that the planets in our solar system weren’t held in place by an invisible bubble but by the Sun’s gravity. Newton’s calculations completely changed the way people looked at the universe.
