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 optical lattice clock, developed in collaboration with The University of Tokyo and RIKEN, is about 100 times more precise than traditional cesium atomic clocks, which currently define the SI ...

They may also set themselves according to atomic clocks. They even adjust when we ... Yet, price doesn’t tell the whole story. Chronometer watches, including many Rolex watches, like the $ ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks ...
