Few people are remembered 350 years after their birth, but then few people are responsible for revolutionising the way the Universe is perceived. Newton say the universe as a world of motion and machinery, governed by mechanical laws. His ideas have dominated science until the arrival of quantum theory in the 20th Century. Isaac Newton was born at Woolsthorpe Manor in Lincolnshire on Christmas Day 1642. His mother left him when he was three and he grew up a solitary child. He had a clever and inventive mind but was resented by his fellow pupils at school. In June 1661 Newton entered Trinity College, at the University of Cambridge. During his four years as a student he attended few lectures, but he experimented and studied on his own. Completely self-taught he emerged as the foremost mathematician in Europe. In 1687 Newton published his "Principia Mathematica", which was based on his work over 20 years. It changed the way the universe was perceived. it stated Newton's laws of motion, showed that Kepler's laws of planetary motion could be derived mathematically assuming an inverse square law of attractive force, and went on to propound universal gravitation. His other major work "Opticks" included Newton's description of his early work on light and colour, which also contained an account of the calculus.
