The physicist, BBC presenter and author on snowflakes, art v science and the time Paul McCartney quizzed him about one of Saturn’s moons
What is the inspiration behind your latest live show, Emergence?
It came from a book that I’ve loved for years: The Six-Cornered Snowflake by Johannes Kepler. Kepler is most famous for his laws of planetary motion in and around 1610, but he wrote this little book about New Year’s Eve in 1609, when he was walking across the Charles Bridge in Prague in a snowstorm. He was going to his benefactor’s house and he hadn’t bought him a present. So he writes this beautiful little book about looking at the snowflakes landing on his arm and thinking about the symmetry of them and asking, why are they six-sided?
