A revolutionary timekeeping breakthrough could be on the horizon as scientists explore the thorium-229 nuclear optical clock, ...

The size, power, and other metrics of a latest-generation chip-scale atomic clock.

Atomic clocks, like China’s new fridge-sized ones ... the new clock works by cooling cool cesium atoms using lasers and then ...

[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules.

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 ...

Modern versions cool atoms to near absolute zero by slowing the atoms down with lasers. With temperature of atoms driving their accuracy. Every few years a 'leap second' is added to atomic clocks ...

The clock hands are set by the Bulletin of the Atomic Scientists, a group formed by Manhattan Project scientists at the University of Chicago who helped build the atomic bomb but protested using it ...

“This is really cool because it directly shows the interplay ... making them extremely difficult to detect. However, atomic clocks are now reaching unprecedented precision, bringing these ...
