Sir Isaac Newton (December 25, 1642 - March 20, 1726/27) was an English physicist and mathematician who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. .
Newton's Principia formulated the laws of motion and universal gravitation, which dominated scientists' view of the physical universe for the next three centuries. Newton built the first practical reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into the many colours of the visible spectrum.

About the Author
Most noted for his contributions to the field of optics, he studied the double refraction by compression and discovered the photoelastic effect, which gave birth to the field of optical mineralogy. For his work, William Whewell dubbed him the "Father of modern experimental optics" and "the Johannes Kepler of Optics."

completed more than one telescope of considerable size; Mr. Raraage, of Aberdeen, has executed reflectors rivalling almost those of Slough; and Lord Oxmantown, an Irish nobleman of high promise, is now engaged on an instrument of great size. But what avail the enthusiasm and the efforts of individual minds in the intellectual rivalry of nations ? ' When the proud science of England pines in obscurity, blighted by the absence of the royal favour, and of the nation's sympathy; when its chivalry fall unwept and unhonoured; how can it sustain the conflict against the honoured and marshalled genius of foreign lands T CHAPTER IV. He delivers a Course of. Optical Lectures at Cambridge Is elected Fellow of the Royal Society He communicates to them his Discoveries on the different Refrangibility and Nature of Light Popular Account of them They involve him in various Controversies His Dispute with Pardies Linus Lucas Dr. Hooke and Mr. Huygens The Influence of these Disputes on the Mind of Newton. Although Newton delivered a course of lectures on optics in the University of Cambridge in the years 1669, 1670, and 1671, containing his principal discoveries relative to the different refrangibility of light, yet it is a singular circumstance, that these discoveries should not have become public through the conversation or correspondence of his pupils. The Royal Society had acquired no knowledge of them till the beginning of 1672, and his reputation in that body was founded chiefly on his reflecting telescope. On the 23d December, 1671, the celebrated Dr. Seth Ward, Lord Bishop of Sarum, who was the author of several able works on astronomy, and had filled the astronomical chair at Oxford,proposed Mr. Newton as a Fellow of the Royal Society. The satisfaction which he derived from thi...
