The clock and the watch

When is it break time? When does the movie start? Can I snooze for a few minutes? The first mechanical clocks were designed in the 1200s to keep track of prayers and working hours.

But the art of measuring time is much older than the clock itself. Water clocks as well as sundials and the practice of dividing up the day into hours took place far before our era begins.

Today the atomic clock is the most precise way of measuring time. It was invented in 1949 and uses the vibration frequency of atoms. The atomic clock deviates a maximum of one second in 100,000 years. Many modern clocks automatically set themselves by the atomic clock, so you know exactly how late you are.
