Something else from my current book

Newton’s Cradle, the executive desktop toy with the suspended ball bearings, was invented by Robert Hooke in 1666. And Newton didn’t invent the reflecting telescope; that was down to the surveyor Leonard Digges well over a century before Newton became someone in 1672. And it was James Gregory’s idea for the mirror, perfected by Hooke, which was used in the Hubble Space Telescope.
