(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 ...

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 ...

Over the years, many new amenities have been installed in space, one of them being atomic clocks. These clocks aid the human population in a myriad of ways, like in GPS navigation, internet timing, ...

Scientists are building a nuclear clock so precise it could detect dark matter and test the laws of physics. The secret? A ...

The world’s most accurate clock now belongs to researchers at the National Institute of Standards and Technology (NIST). Its new optical atomic clock, built around a single trapped aluminum ion, can ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

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 as NIST-F4, ...

An image of a quantum accelerometer, which has been developed by Imperial College London. (Imperial College London) A quantum atomic clock developed at the UK's Defence Science and Technology ...

A thorium-doped calcium fluoride crystal's temperature is continually monitored while a VUV frequency comb is used to directly resolve individual quantum states of the nuclear transition. For decades, ...
