This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. This breakthrough could multiply the ...

The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say.

This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location ...

Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not with the sound of gears or bells, but with the quantum pulse of ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Atomic clocks have served as the world’s most precise means of ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently ...

They may also set themselves according to atomic clocks. They even adjust when we travel into different time zones if they are taken out of airplane mode upon arrival. A radio-controlled clock ...
