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 ...

It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

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, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

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, ...
