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 ...

He worked to develop an atomic clock that is essential to GPS and helped confirm a rare state of matter predicted by Albert ...

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 ...

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.

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.

Watch the 2023 Doomsday Clock announcement: The clock has ticked minutes or seconds toward or away from catastrophe over the years. Wars bring it closer, treaties and cooperation further away.

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 ...

Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

On Tuesday, January 24, 2023, the Bulletin of the Atomic Scientists will reveal how close humanity is to self-annihilation with the unveiling of this year's symbolic Doomsday Clock.

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.

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...
