This book provides a comprehensive introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic ...

Atomic clocks use the oscillations of atoms as timekeeping ‘pendulums’ – which, like grandfather clocks, involve weights suspended from a pivot, the swing of which defines time. When ...

Scientists are developing nuclear clocks using thin films of thorium tetrafluoride, which could revolutionize precision ...

Telling time in space is difficult, but it is absolutely critical for applications ranging from testing relativity to ...

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 ...

That was back in 2001, when he and his colleague Christian Tamm proposed a device with the potential to be even more precise and portable than the world’s best atomic clocks. Peik’s estimate ...

The Department of Defense has awarded quantum technology firm Infleqtion an $11 million contract to help it speed up the ...

In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely ...

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 ...

Key takeawaysAtomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam ...
