The clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say. A new atomic clock is one of the world’s best timekeepers, ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

BRAUNSCHWEIG, Germany — Time measurement is entering a new era. The next generation of atomic clocks uses laser light instead of microwaves to track time, oscillating about 100,000 times faster than ...

The National Institute of Standards and Technology (NIST) U.S. has set a new world record for the most accurate aluminum ion-based optical atomic clock. This clock sets a new time-keeping benchmark, ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

The current methods for attitude determination are Star Trackers, sun sensors, magnetometers, and gyroscopes. We would like ...
