At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

Physicists are exploring thorium-229’s unique properties to create a nuclear clock so precise it could detect the faintest hints of dark matter. Recent measurement advances may allow scientists to ...

India’s caesium fountains are among the only 12 that exist worldwide. Meet the timekeepers at the Indian Standard Time Metrology Division of the NPL in Delhi who keep them running.

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...
