Atomic clocks exploit the properties of atoms to create incredibly precise 'ticks.' Nate Phillips, NIST Most clocks, from ...

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

A portable atomic clock that has been successfully tested at sea could change the future of marine navigation.

What if time could be measured with near-perfect precision? Atomic clocks do exactly that — using atoms as nature’s most ...
