Every school pupil knows that Sir Isaac Newton had the inspiration for his theory of gravity whilst sitting under an apple tree and pondering why apples fall. This lovely story, which was related by Newton himself to several correspondents, occurred in the summer of 1666 - about 350 years ago.

What is perhaps less well-known is that the variety of apple which the famous scientist saw falling from the tree has been positively identified. The incident is known to have taken place in his garden at Woolsthorpe Manor in Lincolnshire - and fortunately there was only one apple tree in the garden. It was subsequently identified as a very old English variety (not surprisingly) called Flower of Kent. It is a large sharp-tasting cooking apple with a juicy crisp flesh, which cooks to a smooth puree.

Even more remarkably, this apple tree, which must surely be the most important in the history of science, is still alive. It appears to have blown over several times in its life, but each time has re-grown from the roots. Many cuttings have been taken from the original tree, and it has become a popular variety in the grounds of university physics departments around the world.
