the more precise these clocks get, the more energy they burn and the more disorder or entropy they create. This has long been seen as an unavoidable cost of keeping precise time. Now, a team of ...

Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

This is because they are still used for the international definition of units of time – the NIST-F1 cesium fountain clock, for example, is the current US civilian time standard clock.

New clock just dropped, but it’ll only drop a second every 30 billion years while in operation. That’s right: It’s the most precise, accurate clock yet built.

Researchers have built an atomic clock that is more precise and accurate than any previous clock. For the first time, the clock can detect the effects of gravity predicted by the theory of general ...

Nuclear clocks would be not only more precise but also simpler and more portable, because unlike atomic clocks they wouldn’t require high vacuum conditions, extreme cooling and powerful ...

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

Chinese scientists have built an ultra-precise clock that they hope will redefine the second Credit: Science Photo Library. This brings humans closer to redefining the second as a basic unit of time.

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

Why do we need precise time on the moon? That 58.7 microseconds may not sound like much to worry about. An eye blink, for example, takes 0.1 to 0.4 seconds , or 100,000 to 400,000 microseconds.
