Chinese scientists create clock so precise it could redefine second - Optical clock measures time using light emitted by ...
The creation of atomic clocks allowed scientists to measure the second independently, based on unchanging features of nature.
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.
Scientists built a strontium clock that could redefine the second. Find out how this ultra-precise timepiece works and its potential uses in navigation and science.
Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and ...
