Christiaan Huygens (1629-1693). Caricature of the Dutch physicist and astronomer Christiaan Huygens. Huygens is best known as the inventor of the pendulum clock. The idea of using a pendulum to measure time had been proposed by Galileo (1564-1642) but he had not found how to keep one swinging. On Christmas Day 1656 Huygens designed a table clock that kept the pendulum swinging by means of a spring. He later made further advances in time-keeping. Huygens also made advances in optics,astronomy,such as discovering the rings of Saturn,and mathematics | |
