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 is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In ...

The geospatial sector, and the wider community, relies on precise timekeeping based on microwave atomic clocks. Is that about ...

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years ...
