His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and he shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.

Newton's Principia formulated the laws of motion and universal gravitation that dominated scientists' view of the physical universe for the next three centuries. By deriving Kepler's laws of planetary motion from his mathematical description of gravity, and then using the same principles to account for the trajectories of comets, the tides, the precession of the equinoxes, and other phenomena, Newton removed the last doubts about the validity of the heliocentric model of the Solar System and demonstrated that the motion of objects on Earth and of celestial bodies could be accounted for by the same principles.
Newton's theoretical prediction that Earth is shaped as an oblate spheroid was later vindicated by the geodetic measurements of Maupertuis, La Condamine, and others, thus convincing most Continental European scientists of the superiority of Newtonian mechanics over the earlier system of Descartes.
Newton also built the first practical reflecting telescope and developed a sophisticated theory of colour based on the observation that a prism decomposes white light into the colours of the visible spectrum.

Newton's work on light was collected in his highly influential book Opticks, first published in 1704. He also formulated an empirical law of cooling, made the first theoretical calculation of the speed of sound, and introduced the notion of a Newtonian fluid. In addition to his work on calculus, as a mathematician Newton contributed to the study of power series, generalised the binomial theorem to non-integer exponents, developed a method for approximating the roots of a function, and classified most of the cubic plane curves.
Newton was a fellow of Trinity College and the second Lucasian Professor of Mathematics at the University of Cambridge. He was a devout but unorthodox Christian, who privately rejected the doctrine of the Trinity and who, unusually for a member of the Cambridge faculty of the day, refused to take holy orders in the Church of England.
Beyond his work on the mathematical sciences, Newton dedicated much of his time to the study of alchemy and biblical chronology, but most of his work in those areas remained unpublished until long after his death. Politically and personally tied to the Whig party, Newton served two brief terms as Member of Parliament for the University of Cambridge, in 1689–90 and 1701–02. He was knighted by Queen Anne in 1705 and he spent the last three decades of his life in London, where he served as Warden (1696–1700) and Master (1700–1727) of the Royal Mint, as well as president of the Royal Society (1703–1727).
Black Death contributed to one of the most important theories in History
In 1665, following an outbreak of bubonic plague in England, Cambridge University was closed, forcing Newton to return home at Woolsthorpe Manor. While there is garden, he saw an apple fall from a tree, an event that inspired him to formulate the famous law of universal gravitation. Newton later told him William Stukeley's incident, the author of his memoirs.

The tree exists today, and some apple that Newton saw him falling that day, in the garden Woolsthorpe Manor was taken into space in 2010 aboard the Atlantis space.
He was interested in alchemy
Isaac Newton was passionate about alchemy. He has devoted a great deal of time trying to create "Philosopher's Stone" which he believed he had the power to turn other metals into gold and to make people immortal.
4. Newton was a member of parliament
Between 1689 and 1690, Newton was a member of Parliament representing Cambridge University. His contribution was limited. He had spoken only once, when he asked a bailiff to close the window because it was cool. At that time he spent in London, Newton was met with several influential figures of the time, including King William III and philosopher John Locke.
5. He was knighted
In 1705 Newton was knighted by Queen Anne. At the time, he was a wealthy man after his mother inherited properties and published two papers bedside. Newton was buried in Westminster Abbey, the burial place of British monarchs, and other notable individuals who do not belong to the royal family (Charles Darwin, Charles Dickens or explorer David Livingstone).
