The most precise clocks in the world will lose only one second every 300 billion years—and someday they might fit in your ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every ...

Nuclear clocks could be more accurate than atomic clocks by a factor of about 10, potentially leading to improved GPS ...

Physicists have made a breakthrough in the development of a nuclear clock, a new kind of ultraprecise clock that could ...

From the humble wristwatch to the atomic clock, innovations that came out of global conflicts transformed our relationship ...

Coordinated Lunar Time will help with precise space-travel calculations. But first, NASA has to figure out how to make it ...

The precision of atomic clocks and the atomic time scale are considered in the context of fundamental physical research, with relation to general relativity and applications such as the Global ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

Atomic clocks typically excite cesium atoms with photons ... in about 0.01 seconds. (The transition time for the bare thorium nucleus 229 Th 90+ is roughly a thousand seconds.) ...

Atomic clocks are the most accurate timekeeping devices we have ... The higher the transition’s frequency, the faster the clock ticks and the more precisely it can keep time. The clock with the best ...
