A team of Chinese researchers has reportedly developed the most precise portable atomic clock ever. Small and rigid by design, this new timepiece can be easily transported to war zones, making it ...

The Global Positioning System (GPS), which provides location information by transmitting signals from satellites, is used for vehicle navigation, as well as the operation of aircraft and ships. While ...

GPS satellites are equipped with atomic clocks that provide precise time. In military operations that involve missile guidance and time-sensitive cyber warfare, time is crucial. Recently ...

Standing 1.5 metres (4.9 feet) tall and roughly the size of a single-door refrigerator, the caesium atomic fountain clock can be loaded onto a military truck and, after enduring long-distance ...

Once China produced weapons-grade uranium, it assembled its first atomic bomb in as little as three to five weeks. Iran may ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

The research could usher in an era of robust and extremely accurate solid-state clocks that could be used in a wide range of commercial and scientific applications. Today, the world’s most precise ...
