  8. 8. The History of the Clocks <ul><li>There is no agreement between historians on the history of the clock. </li></ul>

  14. 14. The Water Clock <ul><li>Water clocks worked better than sundials because they told the time at night as well as during the day. They were also more accurate than sundials. </li></ul>
  15. 15. Pendulum Clocks <ul><li>The first practical clock was driven by a pendulum. It was developed by Christian Huygens around 1656. By 1700, the pendulum clock also had a minute hand. </li></ul>
  16. 16. Pendulum Clocks <ul><li>One problem with pendulum clocks is that they stopped running after a while and had to be restarted. </li></ul>
  17. 17. Means to recharge a pendulum clock <ul><li>Winding the Clock, </li></ul><ul><li>Batteries </li></ul><ul><li>Or </li></ul><ul><li>Quartz Crystal </li></ul>
