Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise global time standard. The new optical clock is so accurate that it loses or ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

China’s strontium optical clock now participates directly in international atomic time calculation Optical clocks operate at higher frequencies than caesium, allowing finer measurement resolution ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
