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 ...

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 ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could ...

The theory was developed by Neils Bohr's great-grandson. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The use of a special type of atom could ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

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 ...
