Newton's descendants gather in Grantham

Now, almost 300 years after his death, Grantham's most famous son is still recognised as one of the most influential scientists of all time.

And plans are well underway to celebrate the life and achievements of Sir Issac Newton - with the second Gravity Fields Festival to be held in at the end of September.

Hosted in his home town, this years four day event evokes a great sense of pride for his descendents.
