A massive moon

... in St Wulfram's Church, Grantham. If you look at the Extras, you can see Mr PP holding it (!), and me - and other visitors - "dancing with Newton" (in the hall of the King's School that Newton - and our son-in-law - attended)! All part of the Gravity Fields events and displays. Mr PP went to some interesting talks this morning, which I decided would be beyond me, not being of a mathematical or physics bent. But it's been a glorious day to be out of doors, so that was good, too. Some of the dances we did were among the oldest written down, from a book of John Playford's Country Dances, dating from 1651.
