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

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

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 ...

It discusses the stability and accuracy of atomic frequency standards, including different types of oscillators and atomic clocks, covering recent developments and uses of these devices. The precision ...

In 2001, Japanese physicist Hidetoshi Katori proposed a new type of atomic clock that only loses a second every 30 billion years, a period longer than the current age of the universe. The ...

It discusses the stability and accuracy of atomic frequency standards, covering different types of oscillators and atomic clocks, and their uses. The precision of atomic clocks and the atomic time ...

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 ...

While the first atomic clock was invented in 1949, no nuclear clock has yet been feasible. The simple reason is that it takes much more energy to excite a nucleus into a higher energy state than ...

HIROSHIMA--Passed down from his grandfather, a U.S.-made wooden clock that hangs on a living room wall at Eiji Koizumi’s home here has stood the test of time and an atomic bomb blast. The ...
