Clocks are the bedrock of modern physics and technology, as they allow scientists to assess fundamental scientific theories, and they make GPS and telecommunications possible. The current gold ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, 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 work, ...

Nasa, in collaboration with the European Space Agency (ESA), has launched two state-of-the-art atomic clocks to the International Space Station (ISS) as part of the Atomic Clock Ensemble in Space ...

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 ...
