Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems — and a ...

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 ...

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 ...

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 ...

An international research team has taken a decisive step toward a new generation of atomic clocks. At the European XFEL X-ray laser, the researchers have created a much more precise pulse generator ...

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 ...
