Clock Lord

Clocks as we know, only display 12 hours at a time. The hour hand must go around the clock twice to measure 24 hours to make a complete day. How do we determine the difference between day time and night time? We have accepted the Latin words: Ante Meridiem - A.M. which means before noon and Post Meridiem - P.M. which means after noon.

In 1510, a man named Peter Henlein invented a spring-powered clock. The clock worked fine, but it was not very precise.  In 1577, Jost Burgi, invented a clock with a minute hand. This clock would prove to have problems keeping precise time as well.  Mankind was hungry for a time piece that would not have the problems of losing precious time with the ticks or the tocks, thus the development of the pendulum clock.

In 1656, Christian Huygens, developed a pendulum clock. The pendulum clock was indeed the first practical clock. This clock was developed because other clocks had problems with precise time mechanisms. The pendulum on the first pendulum clocks would swing about 50 degrees. The improved clocks swung about 10 to 15 degrees, quite a bit less than the original. The problem with pendulum clocks is, they stopped running after a while and had to be restarted. In 1840, the first pendulum clock with external batteries was developed. Further development of the pendulum clock included the batteries inside the clock.
