The watch on your wrist might seem pretty accurate on a day-to-day basis but it’s got nothing when compared to atomic clocks. Scientists use atomic clocks for a variety of purposes, and the more ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado.

Several manufacturers already offer affordable watches that synchronise to the radio signals transmitted from atomic clocks around the world, but Hoptroff's 'No.10' movement is different because it ...

Atomic clocks use these frequencies — specifically, absorbing and emitting photons at regular intervals to keep time. They are the most accurate clock we have to measure time in seconds.

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick ...

Scientists at the National Institute of Standards and Technology track time with atomic clocks. But what is time, really? Physicists are still trying to answer that question.

Chronometer watches, including many Rolex watches, like the $20,000 Rolex Submariner “Hulk” Green Dial Men’s Luxury Watch, are thought to be the most accurate, yet they do not reset themselves.

Scientists have developed the most accurate atomic clock – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve services like ...

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.
