Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Over the years, many new amenities have been installed in space, one of them being atomic clocks. These clocks aid the human population in a myriad of ways, like in GPS navigation, internet timing, ...
