Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

Chinese scientists create clock so precise it could redefine second - Optical clock measures time using light emitted by electrons transitioning between energy levels ...

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 ...

Today’s most advanced clocks keep time with an incredibly precise rhythm. But a new experiment suggests that clocks’ precision comes at a price: entropy. Entropy, or disorder, is created each time a ...

Gregg Perry has finally found his calling. As a horologist — someone who restores and conserves clocks and watches - the Alloway resident, who recently moved back to South Jersey from Pennsylvania, ...
