atomic clock
n.
An extremely precise timekeeping device regulated in correspondence with a characteristic invariant frequency of an atomic or molecular system.

atomic clock
n
(Physics / Atomic Physics) (Miscellaneous Technologies / Horology) an extremely accurate clock in which an electrical oscillator is controlled by the natural vibrations of an atomic or molecular system such as caesium or ammonia

atomic clock
An extremely precise clock whose rate is controlled by a periodic process (such as vibration, or the absorption or emission of electromagnetic radiation) that occurs at a steady rate in atoms or molecules. The standard atomic clock is based on the vibrations of cesium atoms and is so accurate that it would gain or lose less than one second in three million years. Atomic clocks are used to help track satellites, run navigation systems, and study movements of the Earth's crust.

Byline: ANI Berlin, September 4 (ANI): In a new research work, a team of scientists has shown how optical atomic clocks in the future might become more compact and even portable, maybe even travel to space.
Using Atomic Clocks to measure time and space With these atomic clocks, scientists and engineers discovered that there were slight discrepancies in time around the globe.
However, as time-reckoning became more and more sophisticated with the invention of atomic clocks, it was found that the Earth's rotation is not that smooth after all.
