NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...

The National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...
