Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping ...

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that ...

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.

(koto_feja/Getty Images) A breakthrough in chronometry decades in the making could redefine the limits of how we keep time.

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

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 ...

A clock based on radioactive thorium atoms realises a long-held ambition, demonstrating a technology that could eventually ...

(THE CONVERSATION) 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 ...
