WWV signals can be difficult to tune outside of certain hours and weather conditions. It's also fairly difficult to find WWV recievers that can easily plug into computers that aren't expensive bespoke ...

Optical atomic clocks can increase the precision of time and geographic position a thousandfold in our mobile phones, computers, and GPS systems. However, they are currently too large and complex to ...

In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six countries.

In recent years, many physicists worldwide have introduced atomic clocks, systems to measure the passing of time that are based on quantum states of atoms. These clocks can have numerous valuable ...
