Physicists have made a breakthrough in the development of a nuclear clock, a new kind of ultraprecise clock that could ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

coupled an atomic nucleus to an atomic clock to compare differences in their timekeeping frequencies.… The breakthrough promises to ease the development of the next generation of ultra-precise ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

It discusses the stability and accuracy of atomic frequency standards, including different types of oscillators and atomic clocks, covering recent developments and uses of these devices. The precision ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

In 2001, Japanese physicist Hidetoshi Katori proposed a new type of atomic clock that only loses a second every 30 billion years, a period longer than the current age of the universe. The ...

From the humble wristwatch to the atomic clock, innovations that came out of global conflicts transformed our relationship ...

We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?

Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs ...

But a study published in Nature last year suggested that in fact, climate change might be affecting timekeeping in general.
