Sir Isaac Newton, FRS (pronounced /ˈnjuːtən/; was born on 4 January 1643 at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire. At the time of Sir Isaac Newton's birth, England had not adopted the latest papal calendar and therefore his date of birth was recorded as Christmas Day, 25 December 1642. Sir Isaac Newton was born 3 months after the death of his father. Born prematurely, he was a small child; his mother Hannah Ayscough reportedly said that he could have fit inside a quart mug. Sir Isaac Newton died on 31 March 1727 in London and was buried in Westminster Abbey.After Isaac Newton's death, his body was discovered to have had massive amounts of mercury in it, probably resulting from his alchemical pursuits. Mercury poisoning could explain Sir Isaac Newton's eccentricity in late life.
Sir Isaac Newton was an English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian. Sir Isaac Newton's Philosophiæ Naturalis Principia Mathematica, published in 1687, is considered to be the most influential book in the history of science. In this work, Sir Isaac Newton described universal gravitation and the 3 laws of motion, laying the groundwork for classical mechanics, which dominated the scientific view of the physical universe for the next 3 centuries and is the basis for modern engineering. Sir Isaac Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the scientific revolution.
In mechanics, Sir Isaac Newton enunciated the principles of conservation of momentum and angular momentum. In optics, he invented the reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into a visible spectrum. Sir Isaac Newton also formulated an empirical law of cooling and studied the speed of sound.
In mathematics, Sir Isaac Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. Sir Isaac Newton also demonstrated the generalised binomial theorem, developed the so-called "Newton's method" for approximating the 0's of a function, and contributed to the study of power series.
Sir Isaac Newton was also highly religious (though unorthodox), producing more work on Biblical hermeneutics than the natural science he is remembered for today.
In a 2005 poll of the Royal Society asking who had the greater effect on the history of science, Sir Isaac Newton was deemed much more influential than Albert Einstein.
Sir Isaac Newton was 3, when his mother remarried and went to live with her new husband, the Reverend Barnabus Smith, leaving her son in the care of his maternal grandmother, Margery Ayscough. The young Isaac disliked his stepfather and held some enmity towards his mother for marrying him, as revealed by this entry in a list of sins committed up to the age of 19: Threatening my father and mother Smith to burn them and the house over them.
According to E.T. Bell and H. Eves:
Sir Isaac Newton began his schooling in the village schools and was later sent to The King's School, Grantham, where he became the top student in the school. At The King's School, he lodged with the local apothecary, William Clarke and eventually became engaged to the apothecary's stepdaughter, Anne Storer, before he went off to the University of Cambridge at the age of 19. As Sir Isaac Newton became engrossed in his studies, the romance cooled and Miss Storer married someone else. It is said he kept a warm memory of this love, but Sir Isaac Newton had no other recorded "sweet-hearts" and never married.
There are rumours that he remained a confirmed celibate. However, Bell and Eves' sources for this claim, William Stukeley and Mrs. Vincent (the former Miss Storer – actually named Katherine, not Anne), merely say that Sir Isaac Newton entertained "a passion" for Storer while he lodged at the William Clarke house.
From the age of about 12 until he was 17, Sir Isaac Newton was educated at The King's School, Grantham (where his signature can still be seen upon a library window sill). Sir Isaac Newton was removed from school, and by October 1659, he was to be found at Woolsthorpe-by-Colsterworth, where his mother, widowed by now for a 2nd time, attempted to make a farmer of him. Sir Isaac Newton hated farming. Henry Stokes, master at the King's School, who persuaded his mother to send him back to school so that he might complete his education. This he did at the age of 18, achieving an admirable final report.
In June 1661, he was admitted to Trinity College, Cambridge. According to John Stillwell, he entered Trinity as a sizar. At that time, the college's teachings were based on those of Aristotle, but Sir Isaac Newton preferred to read the more advanced ideas of modern philosophers such as Descartes and astronomers such as Copernicus, Galileo, and Kepler. In 1665, he discovered the generalised binomial theorem and began to develop a mathematical theory that would later become infinitesimal calculus. Soon after Sir Isaac Newton had obtained his degree in August of 1665, the University closed down as a precaution against the Great Plague. Although he had been undistinguished as a Cambridge student, Sir Isaac Newton's private studies at his home in Woolsthorpe over the subsequent 2 years saw the development of his theories on calculus, optics and the law of gravitation.
Most modern historians believe that Sir Isaac Newton and Leibniz had developed infinitesimal calculus independently, using their own unique notations. According to Sir Isaac Newton's inner circle, Sir Isaac Newton had worked out his method years before Leibniz, yet he published almost nothing about it until 1693, and did not give a full account until 1704. Meanwhile, Leibniz began publishing a full account of his methods in 1684. Moreover, Leibniz's notation and "differential Method" were universally adopted on the Continent, and after 1820 or so, in the British Empire. Whereas Leibniz's notebooks show the advancement of the ideas from early stages until maturity, there is only the end product in Sir Isaac Newton's known notes. Sir Isaac Newton claimed that he had been reluctant to publish his calculus because he feared being mocked for it. Sir Isaac Newton had a very close relationship with Swiss mathematician Nicolas Fatio de Duillier, who from the beginning was impressed by Sir Isaac Newton's gravitational theory. In 1691 Nicolas Fatio de Duillier planned to prepare a new version of Sir Isaac Newton's Philosophiae Naturalis Principia Mathematica, but never finished it. However, in 1694 the relationship between the 2 men changed. At the time, Nicolas Fatio de Duillier had also exchanged several letters with Leibniz.
Starting in 1699, other members of the Royal Society (of which Sir Isaac Newton was a member) accused Leibniz of plagiarism, and the dispute broke out in full force in 1711. Sir Isaac Newton's Royal Society proclaimed in a study that it was Sir Isaac Newton who was the true discoverer and labeled Leibniz a fraud. This study was cast into doubt when it was later found that Sir Isaac Newton himself wrote the study's concluding remarks on Leibniz. Thus began the bitter Newton v. Leibniz calculus controversy, which marred the lives of both Sir Isaac Newton and Leibniz until the latter's death in 1716.
Sir Isaac Newton is generally credited with the generalised binomial theorem, valid for any exponent. Sir Isaac Newton discovered Newton's identities, Newton's method, classified cubic plane curves (polynomials of degree 3 in 2 variables), made substantial contributions to the theory of finite differences, and was the 1st to use fractional indices and to employ coordinate geometry to derive solutions to Diophantine equations. Sir Isaac Newton approximated partial sums of the harmonic series by logarithms (a precursor to Euler's summation formula), and was the 1st to use power series with confidence and to revert power series. Sir Isaac Newton also discovered a new formula for calculating pi.
Sir Isaac Newton was elected Lucasian Professor of Mathematics in 1669. In that day, any fellow of Cambridge or Oxford had to be an ordained Anglican priest. However, the terms of the Lucasian professorship required that the holder not be active in the church (presumably so as to have more time for science). Sir Isaac Newton argued that this should exempt him from the ordination requirement, and Charles II, whose permission was needed, accepted this argument. Thus a conflict between Sir Isaac Newton's religious views and Anglican orthodoxy was averted.
From 1670 to 1672, Sir Isaac Newton lectured on optics. During this period he investigated the refraction of light, demonstrating that a prism could decompose white light into a spectrum of colours, and that a lens and a 2nd prism could recompose the multicoloured spectrum into white light.
Sir Isaac Newton also showed that the coloured light does not change its properties by separating out a coloured beam and shining it on various objects. Sir Isaac Newton noted that regardless of whether it was reflected or scattered or transmitted, it stayed the same colour. Thus, he observed that colour is the result of objects interacting with already-coloured light rather than objects generating the colour themselves. This is known as Newton's theory of colour.
From this work he concluded that any refracting telescope would suffer from the dispersion of light into colours, and invented a reflecting telescope (today known as a Newtonian telescope) to bypass that problem. By grinding his own mirrors, using Sir Isaac Newton's rings to judge the quality of the optics for his telescopes, he was able to produce a superior instrument to the refracting telescope, due primarily to the wider diameter of the mirror. In 1671 the Royal Society asked for a demonstration of his reflecting telescope. Their interest encouraged him to publish his notes On Colour, which he later expanded into his Opticks. When Robert Hooke criticised some of Sir Isaac Newton's ideas, Sir Isaac Newton was so offended that he withdrew from public debate. The 2 men remained enemies until Hooke's death.
Sir Isaac Newton argued that light is composed of particles or corpuscles, which were refracted by accelerating toward the denser medium, but he had to associate them with waves to explain the diffraction of light (Opticks Bk. II, Props. XII-L). Later physicists instead favoured a purely wavelike explanation of light to account for diffraction. Today's quantum mechanics, photons and the idea of wave–particle duality bear only a minor resemblance to Sir Isaac Newton's understanding of light.
In his Hypothesis of Light of 1675, Sir Isaac Newton posited the existence of the ether to transmit forces between particles. The contact with the theosophist Henry More, revived his interest in alchemy. Sir Isaac Newton replaced the ether with occult forces based on Hermetic ideas of attraction and repulsion between particles. John Maynard Keynes, who acquired many of Sir Isaac Newton's writings on alchemy, stated that "Newton was not the first of the age of reason: he was the last of the magicians." Sir Isaac Newton's interest in alchemy cannot be isolated from his contributions to science.(This was at a time when there was no clear distinction between alchemy and science.) Had Sir Isaac Newton not relied on the occult idea of action at a distance, across a vacuum, he might not have developed his theory of gravity.
In 1704 Sir Isaac Newton published Opticks, in which he expounded his corpuscular theory of light. Sir Isaac Newton considered light to be made up of extremely subtle corpuscles, that ordinary matter was made of grosser corpuscles and speculated that through a kind of alchemical transmutation "Are not gross Bodies and Light convertible into one another, ...and may not Bodies receive much of their Activity from the Particles of Light which enter their Composition?" Sir Isaac Newton also constructed a primitive form of a frictional electrostatic generator, using a glass globe.
In 1677, Sir Isaac Newton returned to his work on mechanics, i.e., gravitation and its effect on the orbits of planets, with reference to Kepler's laws of planetary motion, and consulting with Hooke and Flamsteed on the subject. Sir Isaac Newton published his results in De motu corporum in gyrum (1684). This contained the beginnings of the laws of motion that would inform the Principia.
The Philosophiae Naturalis Principia Mathematica (now known as the Principia) was published on 5 July 1687 with encouragement and financial help from Edmond Halley. In this work Sir Isaac Newton stated the 3 universal laws of motion that were not to be improved upon for more than 200 years. Sir Isaac Newton used the Latin word gravitas (weight) for the effect that would become known as gravity, and defined the law of universal gravitation. In the same work he presented the 1st analytical determination, based on Boyle's law, of the speed of sound in air. Sir Isaac Newton's postulate of an invisible force able to act over vast distances led to him being criticised for introducing "occult agencies" into science.
With the Principia, Sir Isaac Newton became internationally recognised. Sir Isaac Newton acquired a circle of admirers, including the Swiss-born mathematician Nicolas Fatio de Duillier, with whom he formed an intense relationship that lasted until 1693. The end of this friendship led Sir Isaac Newton to a nervous breakdown.
In the 1690s, Sir Isaac Newton wrote a number of religious tracts dealing with the literal interpretation of the Bible. Henry More's belief in the universe and rejection of Cartesian dualism may have influenced Sir Isaac Newton's religious ideas. A manuscript he sent to John Locke in which he disputed the existence of the Trinity was never published. Later works – The Chronology of Ancient Kingdoms Amended (1728) and Observations Upon the Prophecies of Daniel and the Apocalypse of St. John (1733) – were published after his death. Sir Isaac Newton also devoted a great deal of time to alchemy.
Sir Isaac Newton was also a member of the Parliament of England from 1689 to 1690 and in 1701, but his only recorded comments were to complain about a cold draft in the chamber and request that the window be closed.
Sir Isaac Newton moved to London to take up the post of warden of the Royal Mint in 1696, a position that he had obtained through the patronage of Charles Montagu, 1st Earl of Halifax, then Chancellor of the Exchequer. Sir Isaac Newton took charge of England's great recoining, somewhat treading on the toes of Master Lucas (and securing the job of deputy comptroller of the temporary Chester branch for Edmond Halley). Sir Isaac Newton became perhaps the best-known Master of the Mint upon Lucas' death in 1699, a position Sir Isaac Newton held until his death. These appointments were intended as sinecures, but Sir Isaac Newton took them seriously, retiring from his Cambridge duties in 1701, and exercising his power to reform the currency and punish clippers and counterfeiters. As Master of the Mint in 1717 Sir Isaac Newton unofficially moved the Pound Sterling from the silver standard to the gold standard by creating a relationship between gold coins and the silver penny in the "Law of Queen Anne"; these were all great reforms at the time, adding considerably to the wealth and stability of England. It was his work at the Mint, rather than his earlier contributions to science, that earned him a knighthood from Queen Anne in 1705.
Sir Isaac Newton was made President of the Royal Society in 1703 and an associate of the French Académie des Sciences. In his position at the Royal Society, Sir Isaac Newton made an enemy of John Flamsteed, the Astronomer Royal, by prematurely publishing Flamsteed's star catalogue, which Sir Isaac Newton had used in his studies.
Sir Isaac Newton's half-niece, Catherine Barton Conduitt, served as his hostess in social affairs at his house on Jermyn Street in London; he was her "very loving Uncle," according to his letter to her when she was recovering from smallpox.
Although Sir Isaac Newton, who had no children, had divested much of his estate onto relatives in his last years, he actually died intestate.
Historian Stephen D. Snobelen says of Newton, "Isaac Newton was a heretic. But like Nicodemus, the secret disciple of Jesus, he never made a public declaration of his private faith - which the orthodox would have deemed extremely radical. Sir Isaac Newton hid his faith so well that scholars are still unravelling his personal beliefs." Stephen D. Snobelen concludes that Sir Isaac Newton was at least a Socinian sympathiser (he owned and had thoroughly read at least 8 Socinian books), possibly an Arian and almost certainly an antitrinitarian. In an age notable for its religious intolerance there are few public expressions of Sir Isaac Newton's radical views, most notably his refusal to take holy orders and his refusal, on his death bed, to take the sacrament when it was offered to him.
In a view disputed by Snobelen, T.C. Pfizenmaier argues that Sir Isaac Newton held the Eastern Orthodox view of the Trinity rather than the Western one held by Roman Catholics, Anglicans, and most Protestants. In his own day, he was also accused of being a Rosicrucian (as were many in the Royal Society and in the court of Charles II).
Although the laws of motion and universal gravitation became Sir Isaac Newton's best-known discoveries, he warned against using them to view the universe as a mere machine, as if akin to a great clock. Sir Isaac Newton said, "Gravity explains the motions of the planets, but it cannot explain who set the planets in motion. God governs all things and knows all that is or can be done."
Sir Isaac Newton's scientific fame notwithstanding, Sir Isaac Newton's studies of the Bible and of the early Church Fathers were also noteworthy. Sir Isaac Newton wrote works on textual criticism, most notably An Historical Account of Two Notable Corruptions of Scripture. Sir Isaac Newton also placed the crucifixion of Jesus Christ at 3 April, AD 33, which agrees with one traditionally accepted date. Sir Isaac Newton also attempted, unsuccessfully, to find hidden messages within the Bible.
In his own lifetime, Sir Isaac Newton wrote more on religion than he did on natural science. Sir Isaac Newton believed in a rationally immanent world, but he rejected the hylozoism implicit in Leibniz and Baruch Spinoza. Thus, the ordered and dynamically informed universe could be understood, and must be understood, by an active reason, but this universe, to be perfect and ordained, had to be regular.
"Newton," by William Blake; here, Newton is depicted as a "divine geometer" Sir Isaac Newton and Robert Boyle’s mechanical philosophy was promoted by rationalist pamphleteers as a viable alternative to the pantheists and enthusiasts, and was accepted hesitantly by orthodox preachers as well as dissident preachers like the latitudinarians. Thus, the clarity and simplicity of science was seen as a way to combat the emotional and metaphysical superlatives of both superstitious enthusiasm and the threat of atheism, and, at the same time, the 2nd wave of English deists used Sir Isaac Newton's discoveries to demonstrate the possibility of a "Natural Religion."
The attacks made against pre-Enlightenment "magical thinking," and the mystical elements of Christianity, were given their foundation with Robert Boyle’s mechanical conception of the universe. Sir Isaac Newton gave Robert Boyle’s ideas their completion through mathematical proofs and, perhaps more importantly, was very successful in popularising them. Sir Isaac Newton refashioned the world governed by an interventionist God into a world crafted by a God that designs along rational and universal principles. These principles were available for all people to discover, allowed people to pursue their own aims fruitfully in this life, not the next, and to perfect themselves with their own rational powers.
Sir Isaac Newton saw God as the master creator whose existence could not be denied in the face of the grandeur of all creation. But the unforeseen theological consequence of his conception of God, as Leibniz pointed out, was that God was now entirely removed from the world’s affairs, since the need for intervention would only evidence some imperfection in God’s creation, something impossible for a perfect and omnipotent creator. Leibniz's theodicy cleared God from the responsibility for "l'origine du mal" by making God removed from participation in his creation. The understanding of the world was now brought down to the level of simple human reason, and humans, as Odo Marquard argued, became responsible for the correction and elimination of evil.
On the other hand, latitudinarian and Sir Isaac Newtonian ideas taken too far resulted in the millenarians, a religious faction dedicated to the concept of a mechanical universe, but finding in it the same enthusiasm and mysticism that the Enlightenment had fought so hard to extinguish.
In a manuscript he wrote in 1704 in which he describes his attempts to extract scientific information from the Bible, he estimated that the world would end no earlier than 2060. In predicting this he said, "This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fanciful men who are frequently predicting the time of the end, and by doing so bring the sacred prophesies into discredit as often as their predictions fail."
As warden of the Royal Mint, Sir Isaac Newton estimated that 20% of the coins taken in during The Great Recoinage were counterfeit. Counterfeiting was high treason, punishable by being hanged, drawn and quartered. Despite this, convictions of the most flagrant criminals could be extremely difficult to achieve; however, Sir Isaac Newton proved to be equal to the task.
Disguised as an habitué of bars and taverns, he gathered much of that evidence himself. For all the barriers placed to prosecution, and separating the branches of government, English law still had ancient and formidable customs of authority. Sir Isaac Newton was made a justice of the peace and between June 1698 and Christmas 1699conducted some 200 cross-examinations of witnesses, informers and suspects. Sir Isaac Newton won his convictions and in February 1699, he had 10 prisoners waiting to be executed.
Possibly Sir Isaac Newton's greatest triumph as the king's attorney was against William Chaloner. One of William Chaloner's schemes was to set up phony conspiracies of Catholics and then turn in the hapless conspirators whom he entrapped. William Chaloner made himself rich enough to posture as a gentleman. Petitioning Parliament, William Chaloner accused the Mint of providing tools to counterfeiters (a charge also made by others). Sir Isaac Newton proposed that he be allowed to inspect the Mint's processes in order to improve them. Sir Isaac Newton petitioned Parliament to adopt his plans for a coinage that could not be counterfeited, while at the same time striking false coins. Sir Isaac Newton was outraged, and went about the work to uncover anything about William Chaloner. During his studies, he found that William Chaloner was engaged in counterfeiting. Sir Isaac Newton immediately put William Chaloner on trial, but William Chaloner had friends in high places and, to Sir Isaac Newton's horror, William Chaloner walked free. Sir Isaac Newton put him on trial a 2nd time with conclusive evidence. William Chaloner was convicted of high treason and hanged, drawn and quartered on 23 March 1699 at Tyburn gallows.
Enlightenment philosophers chose a short history of scientific predecessors—Galileo, Roger Boyle,and Sir Isaac Newton principally—as the guides and guarantors of their applications of the singular concept of Nature and Natural Law to every physical and social field of the day. In this respect, the lessons of history and the social structures built upon it could be discarded.
It was Sir Isaac Newton’s conception of the universe based upon Natural and rationally understandable laws that became the seed for Enlightenment ideology. Locke and Voltaire applied concepts of Natural Law to political systems advocating intrinsic rights; the physiocrats and Adam Smith applied Natural conceptions of psychology and self-interest to economic systems and the sociologists criticised the current social order for trying to fit history into Natural models of progress. Monboddo and Samuel Clarke resisted elements of Sir Isaac Newton's work, but eventually rationalised it to conform with their strong religious views of nature.
The famous three laws of motion:
Newton's 1st Law (also known as the Law of Inertia) states that an object at rest tends to stay at rest and that an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force.
Newton's 2nd Law states that an applied force, on an object equals the rate of change of its momentum, with time. Mathematically, this is expressed as
Because this relation only holds when the mass is constant, that is, when, the 1st term vanishes, and the equation can be written in the iconic form
This equation states that a force applied to an object of mass m causes it to accelerate at a rate.
This equality requires a consistent set of units for measuring mass, length, and time. One such set is the SI system, where mass is in kilograms, length in metres, and time in seconds. This leads to force being in newtons, named in his honour, and acceleration in metres per second per second. The English analogous system is slugs, feet, and seconds.
Sir Isaac Newton's 3rd Law states that for every action there is an equal and opposite reaction. This means that any force exerted onto an object has a counterpart force that is exerted in the opposite direction back onto the 1st object. The most common example is of 2 ice skaters pushing against each other and sliding apart in opposite directions. Another example is the recoil of a firearm, in which the force propelling the bullet is exerted equally back onto the gun and is felt by the shooter. Since the objects in question do not necessarily have the same mass, the resulting acceleration of the 2 objects can be different (as in the case of firearm recoil).
Newton's apple
Reputed descendants of Newton's apple tree, at the Botanic Gardens in Cambridge and the Instituto Balseiro library garden“ When Newton saw an apple fall, he found
In that slight startle from his contemplation –
'Tis said (for I'll not answer above ground
For any sage's creed or calculation) –
A mode of proving that the earth turn'd round
In a most natural whirl, called "gravitation;"
And this is the sole mortal who could grapple,
Since Adam, with a fall or with an apple.
Newton himself often told that story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree. It fell straight down--why was that, he asked?
Cartoons have gone further to suggest the apple actually hit Sir Isaac Newton's head, and that its impact somehow made him aware of the force of gravity. John Conduitt, Sir Isaac Newton's assistant at the Royal Mint and husband of Sir Isaac Newton's niece, described the event when he wrote about Sir Isaac Newton's life:
“In the year 1666 he retired again from Cambridge to his mother in Lincolnshire. Whilst he was pensively meandering in a garden it came into his thought that the power of gravity (which brought an apple from a tree to the ground) was not limited to a certain distance from earth, but that this power must extend much further than was usually thought. Why not as high as the Moon said he to himself and if so, that must influence her motion and perhaps retain her in her orbit, where upon he fell a calculating what would be the effect of that supposition.”
The question was not whether gravity existed, but whether it extended so far from Earth that it could also be the force holding the moon to its orbit. Sir Isaac Newton showed that if the force decreased as the inverse square of the distance, one could indeed calculate the Moon's orbital period, and get good agreement. Sir Isaac Newton guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation".
A contemporary writer, William Stukeley, recorded in his Memoirs of Sir Isaac Newton's Life a conversation with Newton in Kensington on 15 April 1726, in which Sir Isaac Newton recalled "when formerly, the notion of gravitation came into his mind. It was occasioned by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself. Why should it not go sideways or upwards, but constantly to the earth's centre." In similar terms, Voltaire wrote in his Essay on Epic Poetry (1727), "Sir Isaac Newton walking in his gardens, had the first thought of his system of gravitation, upon seeing an apple falling from a tree." These accounts are probably exaggerations of Sir Isaac Newton's own tale about sitting by a window in his home (Woolsthorpe Manor) and watching an apple fall from a tree.
Various trees are claimed to be "the" apple tree which Sir Isaac Newton describes. The King's School, Grantham, claims that the tree was purchased by the school, uprooted and transported to the headmaster's garden some years later, the staff of the [now] National Trust-owned Woolsthorpe Manor dispute this, and claim that a tree present in their gardens is the one described by Sir Isaac Newton. A descendant of the original tree can be seen growing outside the main gate of Trinity College, Cambridge, below the room Sir Isaac Newton lived in when he studied there. The National Fruit Collection at Brogdale can supply grafts from their tree, which appears identical to Flower of Kent, a coarse-fleshed cooking variety.
