There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and ...

However, aluminum is tricky. The element is difficult to measure with lasers, as well as cool to absolute zero. But when ...

The National Institute of Standards and Technology (NIST) has set a new record by developing the world's most accurate clock, ...

The laser beam traveled 3.6 kilometers (over 2 miles) via fiber optic links to NIST, where a frequency comb (acting as a “ruler for light”) allowed the aluminum ion clock’s laser to adopt its superior ...

Atomic clocks have been used for decades – but now, even greater precision has become possible: TU Wien (Vienna) and JILA/NIST are presenting the world's first nuclear clock. Peer-Reviewed ...

The most precise and accurate atomic clock in the world, the ultracold strontium clock at JILA in Boulder, is like a stopwatch that can count the billionths of a nanosecond, or 18 digits past the ...

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

Atomic clocks are our most accurate timekeepers, losing only seconds across billions of years. But nuclear clocks could steal their thunder, speeding up GPS and the internet. Now, scientists have ...

More accurate strontium-based atomic clocks are possible – and accurate to one second every 40 billion years ... Instead, it was the culmination of three decades of global collaboration.

He worked to develop an atomic clock that is essential to global positioning systems and helped confirm a rare state of ...
