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 ...

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 ...

GPS satellites are equipped with atomic clocks that deliver precise time. In military operations that guide missiles and involve time-sensitive cyber warfare, time is gold. Recently, China ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even ...

When the clock was first depicted on the June 1947 issue—set at seven minutes to midnight—the editors were concerned solely with the likelihood that atomic bombs would soon rain down on the ...

WASHINGTON — Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic ...

One example of this type of sensor is an atomic clock, which goes inside electronic devices to provide the same sort of precision referencing as wireless GPS. They could eliminate the need for the ...

have developed a clock that is not a normal clock but a light-based atomic clock that is the world's most precise and sturdy clock ever. This clock is capable of detecting gravity at a ...

Atomic clocks are the backbone of the Global Positioning System (GPS), the network of satellites above the earth that we use every day to navigate cities, respond to emergencies, and organise ...
