If time is crucial to you or your office, consider investing in atomic clocks so that everyone knows exactly what time it is and everyone has the same time. These are the most accurate time keeping pieces you can get, and more and more businesses are using atomic wall clocks to make sure that accurate time sheets and appointments are kept.
But what are atomic clocks and why are they so much more accurate than regular clocks? A standard clock, whether wind-up, electric or battery operated, counts time by the number of ticks that a resonator makes. The resonator is the device that actually keeps track of time. In most clocks the resonator is either a swinging pendulum or (in digital clocks) oscillations in the power line (which is a bit different in the U.S. and in Europe).
Atomic clocks also use a resonator, but the resonator counts based on the resonance frequency of atoms. Resonance is the emission or absorption of microwave electromagnetic radiation by an atom. It is very regular, and no matter which atom of cesium used, the frequency of resonance is always exactly the same. This is why atomic clocks are so much more accurate than other clocks the resonators in...
