Ekkehard Peik, one of the field’s pioneers, says such a clock could be a factor of 1,000 times better than today’s standard atomic clocks. In atomic clocks, the electrons around an atom’s ...

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

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 ...

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 ...

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.

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

Gaby and Alex’s team developed a chip-scale atomic clock (CSAC) that is a little larger than a peanut. Rubidium atoms in the atomic beam provide the microwave quantum transition that is used by the ...

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 ...

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.

The atomic scientists' Doomsday Clock is now 75—and threats to civilization still abound. A Cold War icon, the clock conveys scientists’ views on humankind’s risk of destroying itself.
