For centuries, sundials and water clocks inaccurately
told us all we needed to know about time. Mechanical
clocks started appearing on towers in Italy in the 14th
century, but their timekeeping was less impressive than
their looks, wandering up to 15 minutes a day. By the
17th century some geniuses, including Galileo and Pascal,
had theorized about, but failed to build, better timepieces.
Then, in 1656, Dutch astronomer Christian Huygens
constructed the first pendulum clock, revolutionizing
timekeeping. The precision of Huygens clock allowed
scientists to use it for their physics experiments, and
shopkeepers to open and close at fixed hours. In 1761,
Englishman John Harrison perfected a clock that worked
at sea and put accurate time in a navigator s pocket.
