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, ...

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 the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

Physicists are preparing to test whether time itself can exist in a quantum superposition, using ultra-sensitive atomic clocks capable of detecting minute fluctuations. The proposed experiment could ...

About a decade ago, physicists put forward a theory that proposes how to investigate the quantum nature of time. It can be possible for clocks to experience superposition, where two different states ...

Every now and then in our travels we come upon a project with such an obvious need that it’s almost a surprise nobody has ...

You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow ...

Hong Kong’s Siobhan Haughey has broken the meet record in the women’s 200m freestyle at the Bergen Swim Festival in Norway. Haughey’s time of one minute, 54.31 seconds not only won gold but was also ...
