A FRAGILE manuscript telling the original story of how Sir Isaac Newton was inspired by a falling apple has been made public for the first time. The handwritten account of Newtons eureka moment, which led to his famous theory of gravity, was recorded for posterity by the scientists fri-end and colleague William Stukeley in a 1752 biography. It is thought to be the first account of one of sciences most famous anecdotes and the one that brought it to the general publics attention. Until now the manuscript has remained hidden away in the Royal Societys archives - but now anyone with internet access will be able to look at it. It is one of a number of archive documents being published online by Britains leading academic institution to mark its 350th anniversary. Lord Rees, president of the Royal Society - and Newtons modern-day successor - said: Stukeleys biography is a precious artefact for historians of science and I am delighted that it is being made available today, along with other treasures from the archives, in a format that allows anybody to view them as if they were holding the manuscript in front of them. Keith Moore, head archivist at the Royal Society, said: This is the account that put the famous anecdote on the map. Telegraph Stukeley, an early antiquarian famous for his studies of Stonehenge, heard how Newtons thoughts turned to gravity as the two men sat in the shade of some apple trees in the scientists garden in the 1720s. The extract, from Stukeleys Memoirs of Sir Isaac Newtons Life, reads: After dinner, the weather being warm, we went into the garden and drank thea (sic), under the shade of some apple trees ... he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasiond 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 ... Stukeley also gathered material about Newtons younger days from residents of Grantham, Lincolnshire, where he went to school. One story tells of the young Newton building a working scale model of a windmill, based on his observations of a full size version. Unimpressed by wind power, Newton went on to construct a fully functional mouse-driven mill which worked it as naturally as the wind. Also available through the Royal Societys Turning the Pages initiative is the design for Thomas Paines revolutionary iron bridge, the philosopher John Lockes contribution to an early version of the American constitution, and rare natural history illustrations from the 17th to the 19th centuries.
