In grade school you probably learned Newton ’s orchard apple tree floor around the time you learned thatGeorge Washington chop down a cherry tree diagram , thatpeople in Columbus ’ clock time thought that the earth was mat , or thatthe Pilgrims fete the first Thanksgiving in America and invited the Native Americans to join them .
Since literally none of the latter three story here are true ( follow the preceding link for full detail ) , you probably have your doubts about whether Newton really sat under an Malus pumila tree and had something of a “ eureka ” moment come to graveness .
It might storm you to learn , then , that your teacher got one of these stories ( partially ) correct . Newton was indeed sit under an apple tree when he had his so - called “ eureka ” moment on how gravity play .
Although , it read him over two decennium more to modernise the fully - fledge possibility of “ universal gravitation ” , first published in his Philosophiæ Naturalis Principia Mathematica on July 5 , 1687 . He also did n’t complete it without some ideas others had already descend up with , such as Christopher Wren , Robert Hooke , and Edmond Halley ( who Halley ’s comet is constitute after ) ; though Newton claims particularly Hooke , who fit heavily with Newton on gravitation , and his ideas had little real bearing on his work , other than merely to inhale him to continue working on the trouble .
As Newton stated when Hooke accuse Newton of plagiarizing his work :
Yet am I not beholden to him for any light into that business but only for the diversion he gave me from my other written report to believe on these things & for his dogmaticalness in penning as if he had found the move in the Ellipsis , which inclined me to try it …
So perhaps “ eureka ” conveys much too strong of a jump . From accounts , he was more just put on the correct path while musing under the tree .
Further , it would seem that the apple did n’t fall instantly on his head- at least there is no document evidence of this . But if you discount the whim that he near instantly fleshed out his universal theory and the “ fell on his head teacher ” bit , the common account is jolly accurate .
One of the good beginning we have for the “ apple fall on Newton ’s head ” anecdote is a manuscript write by Newton ’s admirer William Stukeley . He published Memoirs of Sir Isaac Newton ’s Life in 1752 , becoming one of Newton ’s first biographer . Many of the incidences name in the book of account were recorded much in the first place than 1752 , including the “ Malus pumila ” story which was first documented in 1726 , the yr Newton died , and then again a class subsequently by Voltaire in hisEpic Poetry .
Stukeley ’s chronicle is as follows :
After dinner , the weather being fond , we went into the garden , & drank tea under the spook of some appletrees , only he , & myself . amidst other discourse , he told me , he was just in the same place , as when formerly , the notion of gravitational force came into his mind . “ Why should that apple always descend perpendicularly to the land , ” thought he to him self : occasion’d by the descent of an apple , as he sit in a contemplative humor : “ Why should it not go sidewise , or upwards ? but constantly to the earths centre ? Assuredly , the reason is , that the land draws it . There must be a draft index in issue . & the sum of the drawing power in the issue of the land must be in the earth centre , not in any side of the world . therefore perform this apple fall perpendicularly , or toward the centre . If subject thus draws matter ; it must be in ratio of its quantity . Therefore the orchard apple tree draws the earth , as well as the earth draws the apple .
John Conduitt , Newton ’s assistant and the married man of his niece , told somewhat much the same story . Newton lived with the couple in his later year and dot upon their daughter . When writing about Newton , Conduitt said :
In the yr he retire again from Cambridge on history of the plague to his female parent in Lincolnshire & whilst he was excogitate in a garden it came into his opinion that the same power of gravity ( which made an apple fall from the Sir Herbert Beerbohm Tree to the ground ) was not fix to a certain distance from the world but must extend much farther than was usually thought – Why not as high as the Moon said he to himself & if so that must regulate her apparent movement & perhaps retain her in her arena , whereupon he fell a calculating what would be the burden of that supposition but being absent from books & taking the common estimate in employment among Geographers & our sea adult male before Norwood had measure the earth , that 60 English mi were contained in one degree of latitude his computation did not concord with his possibility & inclined him then to think of a whimsy that together with the force of gravity there might be a mixture of that force which the synodic month would have if it was carry along in a vortex , but when the Tract of Picard of the bill of the earth came out demonstrate that a stage was about 69.12 English mi He began his figuring a new & found it perfectly accordant to his Theory .
The “ yr [ Newton ] retired again from Cambridge ” was 1666 , which means Stukeley ’s transcription of the outcome contract place some 60 long time after it happened . However , both Stukeley and Conduitt , among others , appear to have independently heard the story directly from Newton himself , making it fairish to believe a falling orchard apple tree was , indeed , the source of Newton ’s first pregnant musing over how gravitational force work .
There are many dissimilar places which claim to be the home plate of the Malus pumila tree diagram that inspired Newton ’s theory , but the most potential one — yield the account statement — is located at his family home of Woolsthorpe Manor near Grantham , UK .
And , yes , there is an apple tree there today that is imagine to be the apple tree diagram in query , though it has re - rooted in the meanwhile after being knock over in a tempest in 1890 . Now around 400 years old , the tree and the property are protect by the National Trust .
If you ’re odd , the tree is a Flower of Kent , which does n’t produce very effective apples for eating by today ’s standards , though they are considered good cooking apples . Further , the Malus pumila in head are green , not red as is often depicted in Isaac Newton / apple images .
You ’ll note , of trend , that Stukeley above stated there was more than one orchard apple tree tree there at the time ; so whether this remaining one is “ the ” apple tree is a question ca n’t be definitively answer until someone invents a machine that can take us back in metre to celebrate the event . That being pronounce , Dr Richard Keesing from the Department of Physics at the University of Yorkmakes a moderately undecomposed case for why it probably is the correct tree diagram .
Despite this uncertainty , there are a many Sir Herbert Beerbohm Tree that have been started as grafts from the Woolsthorpe tree , including one at Trinity College in Cambridge which sits beneath the window of the room Newton used when studying there .

Bonus Facts :
Astronomer Alexis Clairaut in 1727 commented on Hooke ’s accusations that Newton stole Hooke ’s work , summing up the position nicely : “ One must not believe that this musical theme … of Hooke diminishes Newton ’s resplendence … the example of Hooke [ serve ] to show what a distance there is between a truth that is glimpsed and a truth that is demonstrated . ” Essentially , Hooke suppose at a whimsey that Newton was able-bodied to prove .
Newton himself never choose to make an prescribed guess at what really was the implicit in mechanism of gravity . In fact , while he take down “ It is enough that gravity does really exist and acts according to the police I have explained , and that it abundantly serves to report for all the gesture of heavenly bodies , ” he also stated “ That one body may move upon another at a distance through a void without the intermediation of anything else , by and through which their action and force may be conveyed from one another , is to me so great an silliness that , I believe , no valet de chambre who has in philosophic matters a competent faculty of mentation could ever fall into it . ”
Besides the above character reference to who Newton recount the “ Malus pumila tree ” story to , two others also gave an account of him say the story to them : Catherine Barton ( his niece ) and Christopher Dawson ( a pupil at Cambridge ) .
It is n’t clear whether Voltaire get a line the “ orchard apple tree ” fib from Newton himself or if he was told it by a common friend or found out about it in some other way . That said , the pair were friends or at least acquaintances , reckon on your definition of “ friends ” . Voltaire was even present at Newton ’s funeral .
In 1976 , Apple Computers briefly used a logotype that have Sir Isaac Newton sit down beneath an apple tree . It was designed by Ronald Wayne , a lesser - known co - father of the company . Apple later vary the logo to the more recognizable rainbow Malus pumila with the sharpness guide out of it .
Newton has been mark in many different room . Perhaps one of the expectant memorial to his genius is a statue by Eduardo Paolozzi which resist near the British Library in London . The statue is ground on an etching of Newton by William Blake .
William Stukeley , Newton ’s biographer , had quite the curriculum vitae himself . In addition to being a doctor , he had a key interestingness in historical monument and is perhaps well know for his excavation of Stonehenge . He was the first person to recognize the alignment of Stonehenge on solstices and attributed the iconic watershed to the Druid . He later became a vicar , had a exquisite interest in Robin Hood , and write music for the flute .
Newton was buried in Westminster Abbey . Not far down the nave , John Conduitt was also buried . According to an lettering , Conduitt “ wished his remains to be set opposite this billet , near to the ashes of the great Newton , to whom he was linked by ties of phylogenetic relation . ”
Mercury was found in Newton ’s hair when it was examined after his death , likely a result of his experiments in alchemy .
Newton was the second scientist to be knight , though it ’s thought he was granted knighthood for political reason rather than his achievements . He was knight in April 1705 , over 100 years after the first dub scientist , Sir Francis Bacon , was given the honour in 1603 .
The value of “ G ” in Newton ’s famous “ universal gravity ” par was n’t accurately determined until 71 years after Newton ’s death and 111 year after he publish the equation .
