Sir Isaac Newton. -
He was born December 25th, 1642, at Woolsthorpe in Lincolnshire, England. His mother sent him to grammar school at Grantham. In 1661 he was sent to study at Cambridge University.
He got his Bachelorís degree in 1665. After this, he returned to Woolsthorpe, because the plague had forced to close all the schools. During these times he kept researching about his interests. In Mathematics he improved the methods used to draw tangents to curves ant to measure the area contained by them. This is now known as Calculus.
He also discovered that white light was a blend of seven different colors, and it could be separated with a prism.
In those times, the stellar bodiesí behavior was one of the most studied topics in natural philosophy. While Newton was doing some observations, an apple fell of its tree. This brought a question to Newtonís mind: Could the force that attracted the apple to the Earth, "attract" the Moon to the Earth too?
From this he developed three laws of motion, that applied to Kepler's laws of orbital motion, became the Universal Gravitation Law. This law says that every particle in the universe are attracted by a force called gravity
Two years later, he returned to Cambridge University and got his Masterís degree. In 1669, he was nominated as Lucasian Professor of Mathematics.
After several disputes about plagiarism in his book Philosophiae Naturalis Principia Mathematica (1687), Newton moved to London. In 1703, Newton was elected president of the Royal Society, charge he maintained for the rest of his life. He died 1727.
