# Sir Isaac Newton Essay

Sir Isaac Newton-one of the greatest minds in history. He was an all-around genius. He was a mathematician, a natural philosopher, an inventor, and an English physicist. Some of the phenomenal things he did include studying how light reacts to reflection, formulating laws of universal gravitation and motion, and built the first ever reflecting telescope. In 1642 Isaac Newton was born into a very poor farming family in Woolsthorpe, England. When he was very young, his grandma took over and raised him. During this time, he and his grandma lived with a man who took Newton under his wing. Newton then discovered his love for chemical operations. Even though Newton was terrible at grammar and school in general, (at his school

Newton continued to stay in contact with Isaac Barrow. He sent some of this work to Barrow, Barrow then made sure Newton’s work was known to several of the leading mathematicians of Britain and Europe. Once he hit age 30, year 1675, Newton suffered a mental breakdown which continued well until 1684. During this time, he was trying to prove to a man named Hooke that particles would spiral into the center of the Earth, rather than form an ellipse. Halley, a man who was also interested in orbits; finally convinced Newton to publish his work. Newton devoted 2 years to work on the project. The result became one of the most important and influential works on physics of all times, ‘Philosophiae Naturalis Principia Mathematica’ (Mathematical Principles of Natural Philosophy) often shortened to Principia Mathematica .The Principia didn’t show up until late summer 1687. When writing the book Newton tried especially hard to make it very difficult to read, so people wouldn’t attack his ideas.

In the early 1690’s, possibly in response to the intellectual exertion of writing the Principia, Newton suffered a period of depression. He started his work on the moon’s motions. A few years later Newton published another great book called Optics which explained the theory of light and color as
