Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical ...

A tomic 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 ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

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 ...

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...

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 ...
