Sir Isaac Newton  was an English physicist, mathematician and astronomer.  Newton built the first practical reflecting telescope in 1668.Isaac Newton was born to a widowed mother (his father died three months prior) and was not expected to survive, being tiny and weak. Shortly thereafter Newton was sent by his stepfather, the well-to-do minister Barnabas Smith, to live with his grandmother and was separated from his mother until Smith's death in 1653.After interrupted attendance at the grammar school in Grantham, LincolnshireEngland, Isaac Newton finally settled down to prepare for university, going on to Trinity College, Camebridge, in 1661, somewhat older than his classmates. There he immersed himself in Aristotle's work and discovered the works of René Descartes before graduating in 1665 with a bachelor's degree. He also developed a theory of light based on the observation that a prism decomposes white light into the colors of the rainbow.ugh Isaac Newton is well known for his discoveries in optics (white light composition) and mathematics (calculus), it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous. His formulation of the laws of motion resulted in the law of universal gravitation.Isaac Newton is widely known for his published work Philosophiae Naturalis Principia Mathematica (1687), commonly known as the Principia. His laws of motion first appeared in this work. It is one of the most important single works in the history of modern science.
