Atomic clocks are designed to measure the precise length of a second, the base unit of modern timekeeping.
In an atomic clock, the natural oscillations of atoms act like the pendulum in a grandfather clock. However, atomic clocks are far more precise than conventional clocks because atomic oscillations have a much higher frequency and are much more stable.
