If GPS goes dark, this atomic clock could keep the world running

This Portable Atomic Clock Maintained Accurate Time on a Rolling Ship at Sea In A Nutshell Australian physicists built a ...

Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

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

How ultraprecise ‘nuclear clocks’ could transform timekeeping

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

A Chip that Keeps Time (Almost) Like an Atomic Clock

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

2025 One-Hertz Challenge: Fixing The Clock That Once Synced The World

The HP 115BR is not one of the most well-known products from Hewlett-Packard. And yet, it was remarkably important nonetheless. This hardware once synced time around the world. Now, for our 2025 ...

A quantum boost for ultra-precise clocks

Nobel laureate Arthur Schawlow’s advice to “never measure anything but frequency” is a central principle of modern precision metrology and timekeeping. Today’s spectroscopy is advanced enough to teach ...

Most accurate space clock to launch – and count down to destruction

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.
