Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

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 ...

One of these 100-year-old self-winding clocks made its way onto my workbench ... worked and connected it to a clock source with atomic precision. Let’s take a look! Clock Synchronization ...

In his new book “Everything Must Go,” Dorian Lynskey recounts two millennia of apocalyptic predictions. Amazingly, it’s not ...

The pendulum of this mid-century beauty is made of the alloy invar ... With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to ...

Unlike optical atomic clocks—which rely on electronic ... film's potential to serve as a frequency reference for nuclear clocks. "We made the thin film, we characterized it, and it looked ...

Researchers have now found a way to make nuclear clocks a thousand times less radioactive and more cost-effective, thanks to a method creating thin films of thorium tetrafluoride (ThF4).

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

Troops on military operations will soon be able to use a British-made atomic clock built with quantum technology instead of GPS for the first time. The quantum clock, which in the next five years ...

Atomic clocks that excite the nucleus of thorium-229 ... have also solved that problem with the development of thin films made from a thorium-229 precursor that requires much less thorium-229 ...

The optical atomic clock uses an electronic transition frequency to tell the time The clock, which uses an electronic transition frequency to tell the time, made an almost identical journey to one ...
