Some alarm clocks do a lot more than tell the time and wake you up. Oregon Scientific, for example, makes a line of self-setting clocks that let you project an image of the digital clock face and ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.

Which atomic clocks are best? The first time zone, Greenwich Mean Time, was established in the late 1600s to assist sailors before the invention of the train and railway in the mid-1800s expanded the ...

Researchers 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 clocks without ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

Which projection clock is best? While advanced mobile devices and smartwatches might make a traditional alarm clock feel like a relic from the past, these trusty devices are still popular, thanks to ...

Physicists at the University of Toronto have developed technology that could power a new generation of optical atomic clocks with the potential to be a hundred times more accurate than those used ...

Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
