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 ...
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 ...
To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.
