Today is the 380th birthday of Isaac Newton.
First law: In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.
Second law: In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma.
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
The world is a better place because he was in it and still feels the loss that he has left.

BEST KNOWN FOR: Isaac Newton was an English physicist and mathematician famous for his laws of physics. He was a key figure in the Scientific Revolution of the 17th century.
Isaac Newton, the principal founder of calculus, optics, and physics, never knew his father, an illiterate but prosperous farmer who died before Newton was born. He was raised in his earliest years by his maternal grandmother, and attended boarding school in Grantham, living with a local apothecary from whom he developed a fascination for chemistry and science in general. He worked as a menial laborer to earn his tuition to Cambridge, graduating without distinction in 1665 and then returning to his family farm for a year and a half while the college was closed due to bubonic plague. In the Spring of 1666, according to legend, Newton saw an apple fall from a tree on the farm and began pondering the laws of gravity and concerning himself with mathematics and physics. His first serious work elucidated the rules of differentiation and integration in 1666, which he called “the method of series and fluxions”.
He was, however, disinterested in publishing his work until 1668, when mathematician Nicolas Mercator wrote a work duplicating some of Newton’s findings. The following year, after publication of Newton’s paper De Analysi (The Analysis), he was named Lucasian Professor of Mathematics at the recently re-opened Cambridge, where he worked for the remainder of his life. He constructed the first functioning reflecting telescope in 1669, based on a design by astronomer David Gregory. After the publication of his paper Theory about Light and Colors in 1672, he became embroiled in a long-running dispute with Robert Hooke of the Royal Society, who unsuccessfully challenged Newton for credit as discoverer of the inverse-square law of gravitational attraction. As a result, for several years Newton again refused to publish further work.
During his time away from the scientific community, Newton conducted never-published work on alchemy and studied the history of the Bible, concluding that the Christian doctrine of the Trinity is a falsehood introduced some four centuries after the time of Christ. In 1675 he published the paper Of Nature’s Obvious Laws, which was also challenged by Hooke. By 1680, however, Hooke and Newton were corresponding cordially and at length over such concepts as inertia and centripetal attraction.
In 1687, with financial backing from his friend and admirer astronomer Edmund Halley, Newton published his masterwork of fluid physics, gravity, and physical mechanics, Philosophiae Naturalis Principia Mathematica (often referred to as simply Principia or by its English title The Mathematical Principles of Natural Philosophy). The book shows that gravitation is a universal force, explaining phenomena from a dropping apple to the precise motions of planets and comets. It also explains Newton’s three laws of motion.
In 1690 he showed that colored light is actually fundamental, meaning that it can recombined to make white light. In 1696 he was appointed Warden of the British Mint and relocated to London, where he again seems to have distanced himself from scientific circles, instead dedicating his efforts to reforming the corruption then rampant in mint management. In 1705 he published Opticks (Optics), laying out the principles of refraction and explaining the nature of light, and he was knighted in the same year.
His other friendships and correspondents included the philosopher John Locke and the mathematicians Richard Bentley and Nicolas Fatio de Duillier. After about 1700 Newton and his followers were involved in another scientific squabble, this time with Gottfried Leibniz over claims initiated by Fatio that Leibniz’s theory of calculus was at least in part stolen from Newton’s work. As the arguments continued and heightened, Newton’s supporters savaged Leibniz for his belief that miracles are exceptions to the laws of nature miracles.
In 1703 he was elected President of the Royal Society, a post he held for the rest of his life and exploited mercilessly to ruin his rivals. In 1712, he compiled the Society’s official report on the dispute between Leibniz and himself over the development of calculus. Unsurprisingly, the report found that Newton’s work was conducted first, and the same report strongly implied plagiarism on the part of Leibniz. Newton also used his post with the Society to officially minimize the credit due to astronomer John Flamsteed for his observations and star charts, and had all mention of Flamsteed’s work edited out of the second edition of Principia in 1713. In his last years, perhaps contrite, Newton wrote that all of his own work amounted to little more than rediscoveries of ancient but forgotten wisdom.
To become a Fellow of Trinity College at Cambridge in 1667 he was required to join the Church of England, take a vow of celibacy, and promise to train for the church’s priesthood. He remained celibate and unmarried for his entire life, but in 1675, probably on account of his heretical stance against the existence of the Holy Trinity, he was granted dispensation from the priesthood portion of his pledge. For most of his adulthood, Newton was a Unitarian and an avid disbeliever in the divinity of Christ, but he kept these perspectives secret due to the political pressures of his time and place. In his latter years he had recurring and increasingly painful bladder stones, and evidence suggests he also suffered from mercury poisoning, presumably brought on by his alchemical experiments. He spent the last weeks of his life nearly immobile in bed, and finally defied the church by refusing last rites as he died on 31 March 1727.
After his death, relatives sent for an assay of his papers and quickly learned of the volume of Newton’s occult and esoteric writings. He had labored secretively throughout his life to reproduce several alchemical experiments, and Newton’s library contained over a hundred books on alchemy. A completed book of chronology, which attempted to square Biblical chronology with Roman, Greek, and Assyrian history, was published after his death. But the majority of his papers were suppressed, and languished in an archive until in 1936 they were divided up and sold at auction, and thus scattered. Some of the papers were bought up by economist John Maynard Keynes, who published an essay “Newton the Man” in which he described Newton’s occult studies and heretical beliefs, calling him “the last of the magicians” and “Copernicus and Faustus in one”.
