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 world’s best atomic clocks rely on the energy transitions of electrons that orbit an atomic nucleus. These clocks are so accurate that they gain or lose only a second every 40 billion years ...

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 ...

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.

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 ...

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 ...

Atomic clocks work by using a laser to bounce the electrons in an atom at a given frequency, while nuclear clocks would theoretically do the same for atomic nuclei, and we are a step closer to ...
