Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Scientists have built the first working nuclear clock, which uses the vibrations of atomic nuclei to keep time. Nuclear clocks have been sought after for more than two decades and could eventually ...

In popular culture, lasers are often portrayed as portable blasters that superheat whatever they hit. Some lasers do deliver tremendous amounts of energy in reality, but for scientists and engineers, ...
