Spinning things are strange. Why does a spinning top stand up? Why doesn't a rolling wheel fall over? How does a falling cat always manage to land on its feet? How can the Hubble Space Telescope turn around in space? How do ice-skaters spin so fast? Taking a look at gyroscopes, this lecture explores the common threads that link all spinning things.
