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

More accurate strontium-based atomic clocks are possible – and accurate to one second every 40 billion years – by emitting radiation in the visible, rather than microwave, spectrum.

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end. According to an announcement from the National ...

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 ...

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 ...

The team works on OASIC, which stands for Optical Atomic Strontium Ion Clock. While current spacecraft utilize microwave frequencies, OASIC uses optical frequencies.

The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight - the theoretical point of annihilation. That is one second closer than it was set last year.

STATEN ISLAND, N.Y. — When Daylight Saving Time arrives next month, we have to set our clocks ahead one hour. But do we, really? Many of the clocks we rely on daily actually do the resetting all ...

The clock was established in 1947 by Albert Einstein, Manhattan Project director J. Robert Oppenheimer, and University of Chicago scientists who helped develop the first atomic weapons as part of ...
