# Who Was Sir Isaac Newton?

Sir Isaac Newton was born on January 4, 1643, but in England they used the Julian Calendar at the time and his birthday was on Christmas Day 1642. He was born in Woolsthorpe, a hamlet in the country of Lincolnshire. His father had died before his birth and his mother had remarried after his birth and left Isaac to be raised by her mother.

He went to King’s School, Grantham from the time he was twelve to seventeen. He was withdrawn by his mother but later returned. He rose to the top of his class in ranking manly to get revenge toward a bully. He then began attending Trinity College in Cambridge in 1661. After receiving his degree he developed his theories on calculus over the span of two years during the plague.

He was a physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian. Sir Isaac Newton had several hobbies, but the two main ones are astronomy and alchemy. From 1669-1701, Sir Isaac Newton worked as a professor of mathematics at Cambridge. It was at Cambridge that he developed a new field of mathematics called calculus: credit is also shared with Gottfried Leibniz for the development of the differential and integral calculus. There is some argument regarding who gets the most credit: Leibniz or other contributed. It was Isaac Newt and with Leibniz who developed the “developed the mathematics of the infinitesimal” which is calculus. This is a most elegant and extraordinary tool of mathematics, as it is a key to advanced analysis of everything in the technical world. This is or have you heard of the “Newton-Leibniz formula” which is a sign for integral, which a method of computation of definite integrals. Sir Isaac Newton discovered and proved the theory of gravitational force and many other contributions to mathematics, optics and physics, but his mots important contribution was appointing Francis Hauksbee as a curator. Sir Issac Newton is most credited with the generalized binomial theorem, valid for an exponent.

He discovered Newton’s identities, Newton’s method, classified cubic plane curves (such as: polynomials of degree three in two variables), made substantial contributions to the theory of finite differences. This was to us fractional indices and to employ coordinate geometry to derive solutions to Diophantine equations. Then there was the Euler’s summation formula in which was harmonic series that was the first to us power series with confidence and to revert power series. He also discovered a new formula for pi. There are three more contributions to mathematics for Sir Isaac Newton: 1. He made mathematics foundation of science. 2. Co-invented calculus. 3. Used mathematics as the decider of science in the form of correct calculations. If the math did not get the right answer the science was wrong. Sir Isaac Newton had insights into the nature of motion, gravity, light and mathematics, that proved to be fundamental to our scientific understanding of the universe that we live in. Newton gave us an accurate mathematical analysis of the basic phenomena of which our world consists. Not only in the development of calculus, he generalized the binomial theorem. He came up with a quick way to approximate a number’s root.

There was some confusion as to who developed calculus Newton or Leibniz. We can give thanks for inventing analytical fluxion type of the Calculus and to Leibniz the differential/integral type of the Calculus. Many things that were vaguely understood before Newton made more sense with the help of Newton’s work. His work was monumental in mathematics as well as science. He developed a complete calculations of rates and relationships much simpler than they would otherwise be. This is used in engineering. Sir Isaac Newton has and did make a great contribution to the world of mathematics as well as science. Sir Isaac Newton was a truly amazing mathematician and scientist. He achieved so much in his lifetime and the amount of discoveries he made can seem almost impossible. He helped make huge advancements in mathematics and created theorems that we still use heavily to this day.
