A breakthrough in chronometry decades in the making could redefine the limits of how we keep time. Using atoms of thorium-229, physicists have built functional clocks based not on the oscillations of ...
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.
Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...
