Isaac Newton's apple tree

December 18, 2023

Isaac Newton's apple tree at Woolsthorpe Manor[1][2] represents the inspiration behind Sir Isaac Newton's theory of gravity. While the precise details of the apple falling on Newton's head may have been exaggerated[3] over time, the significance of the event lies in the profound impact it had on Newton's scientific thinking. The apple tree in question, a member of the Flower of Kent variety, still exists today at the manor. It stands as a living connection to Newton's groundbreaking insights. The tree has become a cherished symbol, and its descendants and clones can be found in various locations worldwide.

The apple incident edit

It is known from his notebooks that Isaac Newton was grappling in the late 1660s with the idea that terrestrial gravity extends, in an inverse-square proportion, to the Moon; however, it took him two decades to develop the full-fledged theory.[4] 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. 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. He guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation".[5]

Newton himself often told the story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree.[6][7][8] The story is believed to have passed into popular knowledge after being related by Catherine Barton, Newton's niece, to Voltaire.[9] Voltaire then 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."[10][11][12]

Although it has been said that the apple story is a myth and that he did not arrive at his theory of gravity at any single moment, acquaintances of Newton (such as William Stukeley) do in fact confirm the incident, though not the apocryphal version that the apple actually hit Newton's head.[13][14][15] Stukeley recorded in his Memoirs of Sir Isaac Newton's Life a conversation with Newton in Kensington on 15 April 1726:[16]

we went into the garden, & drank thea under the shade of some appletrees, only he, & myself. amidst other discourse, he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. "why should that apple always descend perpendicularly to the ground", thought he to him self: occasion'd by the fall of an apple, as he sat in a comtemplative mood: "why should it not go sideways, or upwards? but constantly to the earths centre? assuredly, the reason is, that the earth draws it. there must be a drawing power in matter. & the sum of the drawing power in the matter of the earth must be in the earths center, not in any side of the earth. therefore dos this apple fall perpendicularly, or toward the center. if matter thus draws matter; it must be in proportion of its quantity. therefore the apple draws the earth, as well as the earth draws the apple."

John Conduitt, Newton's assistant at the Royal Mint and husband of Newton's niece, also described the event when he wrote about Newton's life:[1]

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 & if so, that must influence her motion & perhaps retain her in her orbit, whereupon he fell a calculating what would be the effect of that supposition.

The tree edit

The actual story behind Newton's apple tree can be traced back to Newton's time at Woolsthorpe Manor, his family estate in Lincolnshire, England.[17][1][2] During his stay at the manor in 1665 or 1666, it is believed that Newton observed an apple falling from a tree and began pondering the forces that govern such motion.[18] Dendrochronology, done by the Research Laboratory for Archaeology and the History of Art at the University of Oxford, confirms one of the trees in the orchard to be over 400 years old, having regrown from roots surviving from a tree which was blown over by a storm in 1816.[19][1][20] In 1820, part of the blown tree was also cultivated by Lord Brownlow at Belton Park into a tree that came to be known as the Belton tree.[17][1][20]

Other various trees are claimed to be the apple tree which 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.[21] The staff of the (now) National Trust-owned Woolsthorpe Manor dispute this claim.[1]

The apple tree is a culinary apple[22] of the Flower of Kent variety.[18] The Flower of Kent is known for its large and flavorful, but mealy green apples, which were used for cooking and baking.[23] The apple tree still exists today at Woolsthorpe Manor, and it is attended by gardeners, secured with a fence, and cared for by National Trust for Places of Historic Interest or Natural Beauty.[24]

Significance edit

While there is debate regarding the precise details of the apple tree incident, the story has become deeply ingrained in scientific history and popular culture. The apple tree symbolizes the moment of inspiration that led Newton to develop his groundbreaking ideas. It serves as a powerful metaphor for the process of scientific discovery and the ability to perceive patterns in nature.[18][25]

A statue of Isaac Newton, looking at an apple at his feet, can be seen at the Oxford University Museum of Natural History. A large bronze statue, Newton, after William Blake, by Eduardo Paolozzi, dated 1995 and inspired by Blake's etching, dominates the piazza of the British Library in London. A bronze statue of Newton was erected in 1858 in the centre of Grantham where he went to school, prominently standing in front of Grantham Guildhall.

The tree was ranked number five on the TIME TOP 10 Awesome Trees on Arbor Day in 2010,[26] and was chosen as one of the 50 Great British Trees in 2012, the year of Queen Elizabeth II's Diamond Jubilee.[27] Part of the tree was used in the state coach for Queen Elizabeth II's diamond jubilee.[28]

Piers Sellers on his plan for 10cm sample during the mission, Economic Times[29][30]

On 14 May 2010, British-born NASA astronaut Piers Sellers took 10cm fragment of the Newton's apple tree into space as part of the celebrations for the 350th anniversary of the Royal Society, of which Newton was a former president. The tree sample, engraved with Newton's name, was originally taken from the Royal Society's archives and entrusted to Piers Sellers for his 12-day mission aboard the space shuttle Atlantis to the International Space Station (ISS).[31][32][33] After the mission, both the tree sample and the picture was returned to the Royal Society and became part of a historical exhibition.[34]

Seeds of the tree were sent by the European Space Agency into space to the International Space Station on the 2014-15 Principia mission with astronaut Tim Peake.[27][35] As part of the "Pips in Space" research, the seeds floated in microgravity for six months before returning to Earth in 2016 to be raised into young trees.[36] Winners of a competition to host one of the unique seedlings include the National Physical Laboratory,[37] Jodrell Bank Observatory, and the Eden Project.[36] In 2023, 10 saplings from the tree were auctioned to support the upkeep of Woolsthorpe Manor.[38]

Clones edit

There are several genetically identical trees, or clones, of the original apple tree that have been planted around the world. Trinity College in Cambridge, Newton's alma mater, hosts a genetically identical tree, growing outside the main gate of the college below the room Newton lived in when he studied there.[17][39][40] Woolsthorpe Manor gifted five cuttings from Newton's Apple Tree to Loughborough University, located near Newton's childhood home. These cuttings were planted at Loughborough University as part of an initiative to inspire students to think like Isaac Newton.[41] Cambridge University Botanic Garden had a clone of Newton's Apple Tree that stood at the Brookside entrance. Unfortunately, it fell during Storm Eunice.[42] Yet, the garden plans to plant a new clone elsewhere on the premises.[43] National Institute of Standards and Technology (NIST), Gaithersburg campus in the United States had a clone of Newton's Apple Tree planted.[44][20] But it fell over and died in June 2023 due to unknown reasons.[44][45]

Grace Babson, the wife of Roger Babson, was able to pursue her collection, later amounting to over 1,000 editions of Newton materials, being the largest source in the United States.[46][47] In 1995, the Babson College collection was placed on loan to MIT's Burndy Library, and in 2006, to the Huntington Library in San Marino, California, where it is available for scholarly research.[48] Between Sir Isaac Newton Library (now known as Tomasso Hall) and the Lunder Admission Center lay descendants of the original apple trees.[49] Grace also saved the parlour of Newton's last residence before its demolition and created a replica in Babson Park.[50]

From 1997 to 2007, at Inter-University Centre for Astronomy and Astrophysics three endeavors were undertaken to cultivate Newton's Apple Tree brought in by Jayant Narlikar. Some of the trees managed to thrive and produce apples. However, by 2007, the last remaining tree from those attempts had perished.[51]

Other clones can be found at the Massachusetts Institute of Technology (MIT) in the United States planted in 1942,[52] Queens' College, Cambridge planted in 1948,[53] Bushy House part of the National Physical Laboratory planted in 1953,[44] the Royal Astronomical Society,[54][55] TRIUMF planted in 1968,[27] University of York gifted in 1976,[56] Centro Atómico Bariloche planted in 1981,[27] Koishikawa Botanical Gardens in Japan planted in 1981,[57] York University, Toronto planted in 1999,[58] the University of Wisconsin-Madison's Physics Department and Botanical Garden plant on 25 May 2001,[59] University of Nebraska–Lincoln in Nebraska planted in May 2015,[60][61] Brown University in Rhode Island planted on 29 March 2018,[62] King Edward's School in Birmingham planted in 2018,[63] and Argentina's Parque de las Ciencias planted in 2022.[64]

Locations of some of the clones of Isaac Newton's apple tree

More clones can be found at the Parkes Observatory in Australia,[17] the Observatory Science Center at Herstmonceux in East Sussex, Vanderbilt University in Tennessee, West Virginia University and College of William & Mary in Virginia, Case Western Reserve University in Ohio, Houghton University in New York, Babylonstoren in South Africa, Monash University in Melbourne, Tufts University in Massachusetts, the University of British Columbia in Canada, New York Botanical Garden in Bronx, Balseiro Institute in Rio Negro, Orange Agricultural Institute in New South Wales, Wuling Farm in Taiwan, Nankai University in Tianjin, Beihang University in Beijing, Korea Research Institute of Standards and Science (KRISS) in Daejeon, Keiwa College in Shibata, Saitama University in Saitama, Koishikawa Kōrakuen in Bunkyo, and Technical University of Applied Sciences Wildau in Brandenburg.[27]

The East Malling Research Station in East Malling remains the primary supplier of clones of the tree since 1930, but crossing borders can be challenging and plant delivery may be delayed for inspections or possibly quarantine due to worries about invasive pests and plant diseases.[17] Nevertheless, there appear to be two distinct apple trees, the Woolsthorpe or the Belton tree, that are now being cultivated as "Newton's apple tree", despite the fact that the numerous specimens of the tree appear to be fairly similar on the surface. Whether these are specific to the Woolsthorpe or the Belton tree is still up for debate.[1] For example, in 2016, the tree planted at the National Research Council Canada (NRC-CNRC) in Ottawa[27] was discovered to be a fake and not even a Flower of Kent.[17][58]

Isaac Newton s apple tree at Woolsthorpe Manor 1 2 represents the inspiration behind Sir Isaac Newton s theory of gravity While the precise details of the apple falling on Newton s head may have been exaggerated 3 over time the significance of the event lies in the profound impact it had on Newton s scientific thinking The apple tree in question a member of the Flower of Kent variety still exists

1 The apple incident 2 The tree 3 Significance 4 Clones 5 See also 6 References 7 Further readingThe apple incident editIt is known from his notebooks that Isaac Newton was grappling in the late 1660s with the idea that terrestrial gravity extends in an inverse square proportion to the Moon however it took him two decades to develop the full fledged theory 4 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 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 He guessed the same force was responsible for other orbital motions and hence named it universal gravitation 5 Newton himself often told the story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree 6 7 8 The story is believed to have passed into popular knowledge after being related by Catherine Barton Newton s niece to Voltaire 9 Voltaire then 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 10 11 12 Although it has been said that the apple story is a myth and that he did not arrive at his theory of gravity at any single moment acquaintances of Newton such as William Stukeley do in fact confirm the incident though not the apocryphal version that the apple actually hit Newton s head 13 14 15 Stukeley recorded in his Memoirs of Sir Isaac Newton s Life a conversation with Newton in Kensington on 15 April 1726 16 nbsp A wood engraving of Newton s famous steps under the apple treewe went into the garden amp drank thea under the shade of some appletrees only he amp myself amidst other discourse he told me he was just in the same situation as when formerly the notion of gravitation came into his mind why should that apple always descend perpendicularly to the ground thought he to him self occasion d by the fall of an apple as he sat in a comtemplative mood why should it not go sideways or upwards but constantly to the earths centre assuredly the reason is that the earth draws it there must be a drawing power in matter amp the sum of the drawing power in the matter of the earth must be in the earths center not in any side of the earth therefore dos this apple fall perpendicularly or toward the center if matter thus draws matter it must be in proportion of its quantity therefore the apple draws the earth as well as the earth draws the apple John Conduitt Newton s assistant at the Royal Mint and husband of Newton s niece also described the event when he wrote about Newton s life 1 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 amp if so that must influence her motion amp perhaps retain her in her orbit whereupon he fell a calculating what would be the effect of that supposition The tree editThe actual story behind Newton s apple tree can be traced back to Newton s time at Woolsthorpe Manor his family estate in Lincolnshire England 17 1 2 During his stay at the manor in 1665 or 1666 it is believed that Newton observed an apple falling from a tree and began pondering the forces that govern such motion 18 Dendrochronology done by the Research Laboratory for Archaeology and the History of Art at the University of Oxford confirms one of the trees in the orchard to be over 400 years old having regrown from roots surviving from a tree which was blown over by a storm in 1816 19 1 20 In 1820 part of the blown tree was also cultivated by Lord Brownlow at Belton Park into a tree that came to be known as the Belton tree 17 1 20 Other various trees are claimed to be the apple tree which 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 21 The staff of the now National Trust owned Woolsthorpe Manor dispute this claim 1 nbsp Cross section of apples from Isaac Newton s Tree National Fruit CollectionThe apple tree is a culinary apple 22 of the Flower of Kent variety 18 The Flower of Kent is known for its large and flavorful but mealy green apples which were used for cooking and baking 23 The apple tree still exists today at Woolsthorpe Manor and it is attended by gardeners secured with a fence and cared for by National Trust for Places of Historic Interest or Natural Beauty 24 Significance editWhile there is debate regarding the precise details of the apple tree incident the story has become deeply ingrained in scientific history and popular culture The apple tree symbolizes the moment of inspiration that led Newton to develop his groundbreaking ideas It serves as a powerful metaphor for the process of scientific discovery and the ability to perceive patterns in nature 18 25 nbsp Newton statue on display at the Oxford University Museum of Natural HistoryA statue of Isaac Newton looking at an apple at his feet can be seen at the Oxford University Museum of Natural History A large bronze statue Newton after William Blake by Eduardo Paolozzi dated 1995 and inspired by Blake s etching dominates the piazza of the British Library in London A bronze statue of Newton was erected in 1858 in the centre of Grantham where he went to school prominently standing in front of Grantham Guildhall The tree was ranked number five on the TIME TOP 10 Awesome Trees on Arbor Day in 2010 26 and was chosen as one of the 50 Great British Trees in 2012 the year of Queen Elizabeth II s Diamond Jubilee 27 Part of the tree was used in the state coach for Queen Elizabeth II s diamond jubilee 28 I ll take it up and let it float around for a bit which will confuse Isaac Piers Sellers on his plan for 10cm sample during the mission Economic Times 29 30 On 14 May 2010 British born NASA astronaut Piers Sellers took 10cm fragment of the Newton s apple tree into space as part of the celebrations for the 350th anniversary of the Royal Society of which Newton was a former president The tree sample engraved with Newton s name was originally taken from the Royal Society s archives and entrusted to Piers Sellers for his 12 day mission aboard the space shuttle Atlantis to the International Space Station ISS 31 32 33 After the mission both the tree sample and the picture was returned to the Royal Society and became part of a historical exhibition 34 Seeds of the tree were sent by the European Space Agency into space to the International Space Station on the 2014 15 Principia mission with astronaut Tim Peake 27 35 As part of the Pips in Space research the seeds floated in microgravity for six months before returning to Earth in 2016 to be raised into young trees 36 Winners of a competition to host one of the unique seedlings include the National Physical Laboratory 37 Jodrell Bank Observatory and the Eden Project 36 In 2023 10 saplings from the tree were auctioned to support the upkeep of Woolsthorpe Manor 38 Clones edit nbsp nbsp nbsp Reputed descendants of Newton s apple tree at from top to bottom Trinity College Cambridge Bushy House National Physical Laboratory and the Instituto Balseiro library garden in Argentina There are several genetically identical trees or clones of the original apple tree that have been planted around the world Trinity College in Cambridge Newton s alma mater hosts a genetically identical tree growing outside the main gate of the college below the room Newton lived in when he studied there 17 39 40 Woolsthorpe Manor gifted five cuttings from Newton s Apple Tree to Loughborough University located near Newton s childhood home These cuttings were planted at Loughborough University as part of an initiative to inspire students to think like Isaac Newton 41 Cambridge University Botanic Garden had a clone of Newton s Apple Tree that stood at the Brookside entrance Unfortunately it fell during Storm Eunice 42 Yet the garden plans to plant a new clone elsewhere on the premises 43 National Institute of Standards and Technology NIST Gaithersburg campus in the United States had a clone of Newton s Apple Tree planted 44 20 But it fell over and died in June 2023 due to unknown reasons 44 45 Grace Babson the wife of Roger Babson was able to pursue her collection later amounting to over 1 000 editions of Newton materials being the largest source in the United States 46 47 In 1995 the Babson College collection was placed on loan to MIT s Burndy Library and in 2006 to the Huntington Library in San Marino California where it is available for scholarly research 48 Between Sir Isaac Newton Library now known as Tomasso Hall and the Lunder Admission Center lay descendants of the original apple trees 49 Grace also saved the parlour of Newton s last residence before its demolition and created a replica in Babson Park 50 From 1997 to 2007 at Inter University Centre for Astronomy and Astrophysics three endeavors were undertaken to cultivate Newton s Apple Tree brought in by Jayant Narlikar Some of the trees managed to thrive and produce apples However by 2007 the last remaining tree from those attempts had perished 51 Other clones can be found at the Massachusetts Institute of Technology MIT in the United States planted in 1942 52 Queens College Cambridge planted in 1948 53 Bushy House part of the National Physical Laboratory planted in 1953 44 the Royal Astronomical Society 54 55 TRIUMF planted in 1968 27 University of York gifted in 1976 56 Centro Atomico Bariloche planted in 1981 27

Wildau in Brandenburg 27 The East Malling Research Station in East Malling remains the primary supplier of clones of the tree since 1930 but crossing borders can be challenging and plant delivery may be delayed for inspections or possibly quarantine due to worries about invasive pests and plant diseases 17 Nevertheless there appear to be two distinct apple trees the Woolsthorpe or the Belton tree that are now being cultivated as Newton s apple tree despite the fact that the numerous specimens of the tree appear to be fairly similar on the surface Whether these are specific to the Woolsthorpe or the Belton tree is still up for debate 1 For example in 2016 the tree planted at the National Research Council Canada NRC CNRC in Ottawa 27 was discovered to be a fake and not even a Flower of Kent
