Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

the European Laboratory for Nuclear Research, where [Daniel] works as an RF engineer. With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s ...

Optical atomic clocks, on the other hand, use laser light for even greater precision. However, their complexity has so far limited them to research environments. The 'microcomb chip' acts as a bridge ...
