Even your Macbook or smartphone displays time which is synchronized to the NIST-F1 clock, a cesium fountain atomic clock (aka the ‘Atomic Clock’) that is part of a global consortium of atomic ...

JILA researchers are pioneering a nuclear clock using thorium-229, which offers unprecedented stability compared to atomic ...

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 ...

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 ...

The Doomsday Clock is a metaphor that represents how close humanity is to self-destruction, due to nuclear weapons and climate change. The clock hands are set by the Bulletin of the Atomic Scientists, ...

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 ...

ESA's Atomic Clock Ensemble in Space (ACES) has arrived at NASA's Kennedy Space Center in Florida, United States. This cutting-edge European experiment will test fundamental physics from the ...

The size of this setup makes the optical atomic clock impractical for widespread use in applications like smartphones, satellites, or drones. To solve this challenge, the researchers created tiny ...
