Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

The world’s network of atomic clocks is already mind-bogglingly accurate. They also underpin a slew of modern necessities, ...

Nuclear clock technology made history as two independent teams -- Vienna's TU Wien and Beijing's Tsinghua University -- simultaneously built the world's first working thorium-229 nuclear clocks. The ...

Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...

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 ...

Imagine you're trying to keep time by listening to a room full of people clapping. If everyone claps randomly, it’s hard to tell the rhythm. But if they clap in sync, the beat becomes clear and steady ...

[Bill Hammack] aka [Engineerguy] is back again with another fantastic informational video. This time around he’s describing exactly how an atomic clock does what it does. He starts off with a great ...

Two research groups have built nuclear clocks for the first time, creating ultra-precise devices that measure time through ...

Scientists in Austria and China have built working thorium-229 nuclear clock prototypes that could eventually surpass atomic ...
