Do moon phases affect fishing success? Explore the history of Solunar theory and see how the Citizen Tsuki-yomi A-T watch lets you track moon phases in style.

He worked to develop an atomic clock that is essential to global positioning systems and helped confirm a rare state of ...

Last month, a consortium of 69 scientists from across Europe and Japan completed the largest and most coordinated comparison ...

Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David Gozzard, an ...

So far, the shortest day ever recorded was July 5, 2024, when Earth rotated 1.66 milliseconds faster than usual. This year, ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch.

A low-noise chip-scale atomic clock (LN-CSAC), the SA65-LN from Microchip, features a profile height of less than 0.5 in. (12.7 mm). Aimed at aerospace and defense applications where size, weight, and ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

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 ...

The world’s first nuclear clock is on the horizon It would be 1,000 times more accurate than today’s atomic timekeepers ...

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end.
