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.

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

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, ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same ...

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...
