Newton was an English physicist and mathematician who was born into a poor-farming family. He was not a good farmer at all. So he was sent to Cambridge to study to become a preacher. He then was influenced by Euclid to study mathematics. That was around the time when he made most of his significant discoveries. With his ignorance he waited to later in life to show the world his calculations. Which he didn’t publish most of his work. Newton suffered a mental breakdown in 1675 and was still recovering in 1679. He continued his calculations of the orbits of the planets. Again, he didn’t publish his calculations. After a while he started devoting his time to theological speculation and put the calculations on elliptical motion aside. Which he lied to Halley telling him he had lost them. Halley who then became interested in orbits, finally had become interested in orbits, then he convinced Newton to expand and publish his calculations. He spent from August 1684 till spring 1686 to this task. After he had published them in result became one of the most important and influential works on physics of all time. In book 1 of Principia, Newton opened with definitions and the tree laws of motion now known as Newton’s Law (laws of inertia, action and reaction, and acceleration proportional to force). Book 2 presented Newton’s new scientific philosophy, which came to replace Cartesianism. Finally, book 3 consisted of applications of his dynamics, including an explanation for tides and a theory of lunar motion. He then made another theory which he sooner confirmed, that when Saturn gets close to Jupiter it slows down cause of the universal gravitational pull. Then Flamsteed wrote back in great surprise that he was right. They then did really close observation to make sure they were right. These rules were stated in the Principia and proposed that (1) we are to admit no more causes of natural things such as are both true and...
