A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time exhibits tiny intrinsic ...

Add Yahoo as a preferred source to see more of our stories on Google. For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

The quantum clock design proposed by this team of researchers challenges the long-held assumption that increasing the precision of time-keeping devices comes at a cost, namely an increase in energy ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

National Semiconductor Corporation introduced a family of five precision clock conditioners that integrate all the functions required to clean and distribute ultra-low-noise clock signals throughout a ...

The low-energy excited state of thorium-229 (229Th) isotope nucleus has recently gained much attention owing to it being an ideal candidate for ultra-precise nuclear clocks. Building such ...

Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out ...

As the precision and portability of atomic clocks continue to improve, University of Delaware physicist Marianna Safronova and collaborators Yu-Dai Tsai of the University of California, Irvine, and ...
