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

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 ...

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 ...

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 ...

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

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 ...

The European Space Agency has launched two atomic clocks on a SpaceX rocket to the ISS to test Einstein's theory of ...

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 ...

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 ...

Atomic clocks keep getting smaller ... The design is based on Microchip’s unique Evacuated Miniature Crystal Oscillator (EMXO) technology that’s integrated into the CSAC, enabling the model ...

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 ...
