Pocket Profile: Sir Isaac Newton
I chose Isaac Newton because he was one of the more influential on modern society than any other man. Newton was born December 25 in 1642 in Woolsthorpe Linconshire. He was born into a family of farmers, but his dad died before he was born. His mother remarried and left him to live with his grandmother. Young Isaac was not interested in school and did not do well, he preferred making simple contraptions on the farm. Leaving school at 14 to be a farmer did not work out well because he was very bad at farming. However he returned to school and attended Cambridge College. Newton's major discoveries came in the fields of mechanics, mathematics,gravity and optics. He came up with the laws of motion that explain how things move and how force affects them. His law of inertia states that an object at rest will stay at rest unless acted upon by an outside force. Also, he stated that what goes up, must come down. He described force as the rate of change of an objects linear momentum with its time. Then he concluded that for every action there is an opposite reaction. Continuing with his gravitational theory that what goes up must come down he made a law of gravity. This law stated that, "every particle of matter attracts every other particle of matter with a force along the straight line joining them and is directly proportional to their masses, while inversely proportional to the square of the distance between them." It is said he concluded all this from an apple falling on his head. His inspiration for his discoveries on gravity came when he was sitting under an apple tree and an apple fell on his head. The apple falling on his head made him ask why it fell downward and hit his hard, he named the reason gravity. Isaac also had some intriguing discoveries in optics, the study of light and its behavior. He invented a new type of microscope, the reflection microscope. By studying the behavior of light using a prism he found that white...
