I don’t really have much to report here today. Yesterday was a lovely day: I went to Cambridge with John, and then came back. He had some business to do at the university, and invited me to go with him, just so I could explore the city. It was a short, hour-long train trip from Liverpool Street, before I spent an afternoon in a beautiful little city. I enjoyed looking at all the book shops and cafes, but that’s about it. highlights included glimpsing the tree Newton apparently was sitting under when he came up with gravity, and (best of all) walking around the park where this was filmed.
