The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that ...

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

Atomic clocks have long been the gold standard for ... The ability to access a nuclear state with light makes thorium-229 a unique candidate for a nuclear optical clock. This isn’t just a ...

Current atomic clocks, which use cesium atoms and microwaves ... At the heart of this innovation is a unique design using a mixed-species “Coulomb crystal,” a precise arrangement of different ...

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 ...

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

Using a specialized laser beam called the “magic wavelength,” the clock confines atoms within a lattice structure like eggs in a carton. The purpose is to suppress atomic vibrations and ...

How do we know Einstein had it right? One experiment in the 1970s provided some pretty strong evidence: Atomic clocks are extremely accurate clocks that can measure tiny amounts of time ...

The European Space Agency (ESA) has launched ACES, or the Atomic Clock Ensemble in Space, to the International Space Station (ISS). This project will measure time with a precision never reached ...
