Precision equipment manufacturer Shimadzu Corp. said it has created the world’s most accurate time device: a clock that won’t ...

Tucked away in a vault in France is a weight made of platinum and iridium, diligently cared for by a team of highly trained specialists. Its sole purpose is to be, to sit and remain unchanging as the ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Scientists have created a clock so precise it could redefine the second. The strontium optical lattice clock is one of the most accurate timepieces ever made, capable of measuring seconds to 19 ...

Optical clocks represent the forefront of timekeeping and frequency metrology, exploiting ultranarrow electronic or vibrational transitions in atoms or molecules confined by optical potentials. By ...

University of Wisconsin–Madison physicists have made one of the highest performance atomic clocks ever, they announced Feb. 16 in the journal Nature. In another verification of the validity of ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

The next generation of atomic clocks "ticks" at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.
