have developed an innovative atomic clock that achieves unprecedented precision, with an uncertainty of just 2.5 parts in a quintillion. To help visualize this extraordinary precision: if this ...

The best clocks ever developed are known as optical clocks, and their beat has a precision of the order of a few parts per one billion billion (10), and that is getting better all the time.

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...
