Sir Isaac Newton was born on 25 December 1642– 20 March 1727. He was a natural philosopher, and generally regarded as the most original and influential theorist in the history of science who is widely recognized and as one of the most influential scientists of all time. He was also a key figure in the scientific revolution. His book Philosophiae Naturalis Pricipia Mathematica ("Mathematical Principles of Natural Philosophy"), was first published in 1687 which laid the foundations for classical optics. Newton also made seminal contributions to optics and shares credit with Gotfreid Leibniz or the invention of infinitesimal calculus. In addition, to creating the infinitesimal calculus theory, Newton had transformed the structure of physical science with the three laws of motion that we all have came to know.
In 1666, as story has told us, Newton wached an apple fall off a tree in his garden at Woolsthorpe, later saying, 'In the same year I began to think of gravity extending to the orb of the Moon.' Newton's memory was not accurate. In fact, all evidence believe that the concept of universal gravitation did not spring full-on in Newton's head in 1666 but was nearly 20 years in hibernation.
On April 1667, Isaac Newton had returned to Cambridge university and, against stiff odds, he was elected a minor fellow at Trinity. His success came good fortune. In the next year he became a senior fellow upon taking his master of arts degree, and in 1669, before he had reached his 27th birthday, he succeeded Isaac Barrow as Lucasian Professor of Mathematics. The duties of this appointment gave Newton the chance to organize the results of his earlier research. In 1672, after his election to the Royal Society, he had communicated his first pub...

...s theory of light was in essence “corpuscular”, or particulate. In effect, since light (unlike sound) travels in straight lines and casts sharp shadows, Newton gave the impression that light was composed of small particles moving in straight lines in the manner of inert bodies. Furthermore, since experiments had shown that the properties of the separate colors of light were constant and unchanging, so too, Newton reasoned, was the stuff of light itself-- particles.
Newton's research in dynamics falls into three periods of time: the years of plague 1664-1666, the researches of 1679-1680, following Hooke's correspondence, and the period 1684-1687, following Halley's visit to Cambridge University. The gradual evolution of Newton's thought over these two decades illustrates the difficulty of his accomplishment as well as the prolonged character of scientific discovery.
