Sir Isaac Newton Essay

Sir Isaac Newton (1642-1727)Sir Isaac Newton was an English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian. He was an extremely influential scientist and his book "Philosphiae Naturalis Principia Mathematica" (published 1687) produced the foundations of classical mechanics. It is regarded as one of the most influential books in the history of science.

Born as a premature child on Christmas day 1642 in Woolsthorpe, Newton was the son of an illiterate but prosperous farmer who had died three months prior to his birth. Newtown had an unhappy and emotionally stressful childhood. His mother, Hanna, left him in the care of his grandmother while raising the family of her second husband in the neighbouring town.

Newton was removed from school in 1659 to become a farmer like his father, however he failed at this and returned to school to complete his education. In June 1661, Newton left Woolsthorpe for Cambridge University. He was deeply engrossed in private study during his undergraduate years, and developed his first theories on calculus, optics and the law of gravitation during private studies in Woolsthorpe when the University was closed for two years due to the plague in 1665.

Newton achieved his bachelor's degree without honors or distinction but was successful later on, becoming a Lucasian Professor of Mathematics at Cambridge. He died unmarried in London on March 20 1727Sir Isaac Newton's career was long, with many successes and contributions to science. Among his most important were his work on the nature of gravity, his Laws of Motion, extensive work on light and colour, and his creation of the reflecting telescope.

One of Newton's earliest and most recognised works was his Universal Law of Gravitation. This law stated that, "All bodies attract each other with a force proportional to the product of their masses, and inversely proportionate to the square of the distance between them."This law has several important features:•The strength of force between two massive objects decreases in proportion to the square of the distance between them as they move apart.

•The direction in which the force acts is always along the line connecting the two gravitating objects•Gravity is always an attractive force. There is no negative mass•Gravity is a relatively weak force compared to the other three fundamental forces in nature. Gravity is only significant when very large masses are being considered.

Newton's work with gravity led to his work with the Laws of Motion. He established three Laws of...

Sir Isaac Newton

1643 words - 7 pages Isaac Newton may have been the greatest and most influential scientist and mathematician in history, but he would not appreciate that title.  For Newton didn’t invent calculus and create the basis for modern physics under pressure and for a purpose, he was, as he said “only like a boy playing on the sea shore” (Gleick 4).  Newton, for most of his life, was quiet and kept his work to himself.  He suffered a rather formalistic childhood without a...

The Contributions of Isaac Newton Essay

830 Words4 Pages

Of all of the early scientists of the scientific revolution I am most impressed by Sir Isaac Newton. Newton is important because he contributed more to the development of science than any other person in history. Isaac Newton is remembered as the greatest scientific genius who ever lived. His discoveries about physics, light, and mathematics changed the world. I am even more impressed by what he overcame to reach his goals. He came to surpass even his own expectations. I am more impressed with the man than with the discoveries. So many people in history are viewed as larger than life, which can be dehumanizing. Newton was very much a human with very human emotions. Isaac Newton came from a family of…show more content…

Isaac was allowed to return to the Free Grammar School to complete his education. From there he went to Trinity College Cambridge in 1661. He was older than most of the other students. Despite the fact that his mother was very well off he was entered as a sizar, a student who receives and allowance toward college expenses for acting as a servant to another student. Isaac's goal at Cambridge was a law degree. Education at Cambridge was dominated by the philosophy of Aristotle. He also studied the philosophy of Gassendi, Hobbes, Descartes, and Boyle. He was attracted to the mechanics of Coperican astronomy of Galileo. He also studied Keeper's Optics. Isaac wrote his thoughts in a journal which he called Quaestiones Quaedam Philosophicae (Certain Philosophical Questions). It is an account of how Newton's brilliant ideas were already forming. The text was headed with a Latin statement which read "Plato is my friend, Aristotle is my friend, but my best friend is truth" presenting himself as a free thinker from an early age. In 1663, Isaac's awareness in mathematics began when he bought a book at a fair in Cambridge and found that he could not understand the mathematics in it. Attempting to read a trigonometry book, he found that he lacked the knowledge of geometry and so decided to read Euclid's Elements. Isaac Newton was elected a
