1.1 Philosophiæ Naturalis Principia Mathematica (1687).

Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. His book Philosophiæ Naturalis Principia Mathematica ( Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. He was a key figure in the philosophical revolution known as the Enlightenment. Sir Isaac Newton ( Janu– Maor in Old Style: Decem– March 20, 1727) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a ' natural philosopher'), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time.

172.I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me. Carter & Muir, Printing and the Mind of Man (1967) no. Norman Library of Science and Medicine (1991) no. The first edition of the Opticks ends with two mathematical treatises in Latin, written to establish his priority over Gottfried Wilhelm Leibniz in the invention of the calculus. Nevertheless, Newton preferred the corpuscular theory of light, with which he is usually associated, because of its explanatory value for certain optical phenomena and because it a llowed him to link the action of gross bodies with the action of light. His discovery of periodicity in Newton's rings, which would later prove to be so useful to Thomas Young, led Newton to postulate that periodicity was a fundamental property either of light waves or of waves associated with light. The book summarized Newton's discoveries and theories concerning light and color: the spectrum of the sunlight, the degrees of refraction associated with different colors, the color circle (the first in the history of color theory), the invention of the reflecting telescope the first workable theory of the rainbow, and experiments on what would later be called 'interference effects' in conjunction with Newton's rings. Unlike most of Newton's works, Opticks was originally published in English, with the Latin version following in 1706.

Isaac Newton published Opticks: Or a Treatise of the Reflexions, Refractions, Inflexions and Colours of Light. Also Two Treatises of the Species and Magnitude of Curvilinear Figures in London in 1704.
