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

These optical atomic clocks have broken record after ... This was the first actual demonstration of clock operation with such uncertainty. The system still has a lot more potential.

This 20 GHz offset frequency will serve as the clock signal that is electronically detectable. In this way, we could get the system to transfer the exact time signal from an atomic clock to a more ...

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 ...

They may also set themselves according to atomic clocks. They even adjust when we travel into different time zones if they are taken out of airplane mode upon arrival. A radio-controlled clock ...
