Abstract: This paper presents the development of a MEMS-based reflection-type vapor cell combined with metasurfaces, which function as essential optical components for a microfabricated atomic clock.

Thanks to a speed-up of Earth's rotation, the length of the astronomical day and the length of the clock day aren't quite matching up. Eventually, international timekeepers may need to subtract a ...

Fort Collins received a mention in the new Apple TV sci-fi show "Pluribus." The show references the city's time signal radio station, WWVB, operated by the National Institute of Standards and ...

(CNN) — The biggest event in New Zealand on Thursday may have been the opening of a furniture store. Eager shoppers counted down “3… 2…1” and waved Swedish ...

During the summer of 2025, Iran experienced an exceptional heatwave, with daytime temperatures across several regions, including Tehran, approaching 50 degrees Celsius (122 degrees Fahrenheit) and ...

Denny Chimes is now synced to atomic clock precision, making the clock tower more accurate than ever. Thejesh Bandi, an associate professor in the department of physics and principal investigator of ...

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...

Amazon is selling the Echo Spot smart speaker for just $50 as part of a Black Friday promotion. The sale applies to multiple colorways and represents a discount of $30. This isn't a record low price, ...

The Pseudo Random Pursuit Strategy (PRPS) has been proven to be an effective predictive algorithm for atomic clocks. In this paper, the Fast Pseudo Random Pursuit Strategy (FPRPS) is proposed to ...

Are you one of the many people who either inherited an old clock or found one you love for its artistry and craftsmanship, but it doesn’t work, and you have no idea what to do with it? Such was my ...
