The accuracy of scientific observations and calculations is always at the mercy of the scientist's timekeeping methods. For this reason, scientists are interested in devices that give promise of more precise timekeeping.

In their research for precision, scientists have turned to

atomic clocks that depend on various vibrated atoms or molecules to supply their \

of atom or molecule has its own characteristic rate of vibration. The nitrogen atom in ammonia(氨), for an example, vibrates or \24 billion times a second.

One such atomic clock is so accurate that it will probably lose more than a second in 3,000 years. It will be of great importance in fields such as astronomy. Cesium(铯)is an atom that vibrates 9.2 billion times a second when heated to the temperature of boiled water. An atomic clock that operates with an ammonia molecule may be used to check the accuracy of predictions based on Einstein's relativity theories, according to it a clock in motion and a clock in rest should keep time differently. Placed in an orbiting satellite moving at a speed of 18,000 mile an hour, the clock could broadcast its time readings to a ground station, where they would be compared with the readings on a similar model. However differences develop would be checked against the differences predicted.
