Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

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.
