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

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

(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 ...

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 ...

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 ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

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.
