Oxford physicists create network of quantum-entangled atomic clocks

Physicists at the University of Oxford have successfully linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to approach the fundamental limit of precision set by quan… Continue reading Oxford physicists create network of quantum-entangled atomic clocks

Best time of day to exercise seems to be different for men and women

The best time of day to exercise is a long-standing question, and now a new study suggests that it differs by sex. The team found that evening exercise was more effective for men than morning routines, while results for women varied, with different hea… Continue reading Best time of day to exercise seems to be different for men and women

Cosmic timekeeping tech works underground or underwater

The movements of the Sun, Moon and stars have long been used to keep track of time, and now engineers from the University of Tokyo have proposed a new way to use the cosmos to precisely track time, using showers of particles from cosmic rays.Continue R… Continue reading Cosmic timekeeping tech works underground or underwater

HMS Prince of Wales becomes first surface ship to carry an atomic clock

Britain’s supercarrier HMS Prince of Wales has become the first surface ship to be equipped with a state-of-the-art atomic clock as it departs for the Exercise Cold Response 2022 NATO joint exercises off the north coast of Norway.Continue ReadingCatego… Continue reading HMS Prince of Wales becomes first surface ship to carry an atomic clock

Physicists measure gravitational time warp to within one millimeter

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest d… Continue reading Physicists measure gravitational time warp to within one millimeter
