At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's 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 ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

QuantX personnel conducting environmental testing on the optical frequency comb, which is a key optical atomic clock technology that will be launched into space for testing. (QuantX Labs ...

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch. Where and why tiny ...

A Chip-Scale Atomic Clock (CSAC) is an essential reference for ... enabling the model SA65-LN to offer a reduced profile height of less than ½ inch, while maintaining a power consumption of ...

Monitor deals are rarely this inexpensive: Walmart just knocked $50 off the Onn. 24-inch FHD Gaming Monitor. Usually priced at $149, it’s down to $99, which is a steal of a deal for a gaming ...

Feb. 16, 2022 — Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...
