Many children know this story . A young man sits under a tree . An apple falls on his head . He was a famous scientist . In 1726 Newton was an old man . He had tea in a garden with a friend . His name was William Stukeley . There were apple trees in the garden . Newton remembered an apple from his young years . In Newton 's story , the year is 1666 . A bad illness closed his university . So he went home to his family 's farmhouse . There he saw an apple come down from a tree . Did the apple come down on his head ? Stukeley wrote about the day in a book . He did not write about a head . Other people added the head many years later . Newton had a real question . Why does an apple always go straight down ? His answer : the Earth pulls it . Then he had a bigger idea . Maybe the same pull goes up to the Moon . The Earth pulls the Moon too . So the Moon goes around the Earth . No apple came down on Newton 's head . But a small apple and the big Moon have the same pull .
