Atomic clocks are highly accurate timekeeping devices that use atoms to measure time. By counting the vibrations of atoms, they can keep time with incredible precision. Full definition
This shift can throw off the accuracy of atomic clocks. (sciencedaily.com)
The stability and accuracy of the system, he says, should be comparable to that of microwave - based atomic clocks on today's GPS satellites, which are bulky and expensive. (sciencedaily.com)
Now optical atomic clocks offer a new approach, because the tick rate of a clock is influenced by gravity. (sciencedaily.com)
