Newton's Apple Tree Notecard :
Newton's Apple Tree at NPL



Sir Edward Salisbury, Director of Kew Gardens presented the tree to the National Physical Laboratory in 1953.

It is derived from a graft taken from an old tree in Newton's family garden in Woolsthorpe, near Grantham in Lincolnshire.
According to popular accounts, it was the fall of an apple from this tree that suggested to Newton that the force of gravity that caused the apple to drop to Earth was the same force that kept the moon on its path. The original tree was cared for until it was blown down in 1820 ("Notes and records of the Royal Society Vol 9").
