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 clocks without ...

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 rewrite ...

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 ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...
