What is the identify of the extremely correct atomic clock created by the National Institute of Standards and Technology (NIST) in Colorado?
- NIST-Alpha Clock
- NIST-F1 Cesium Fountain Clock
- NIST-Time Master
- NIST-Precision Timekeeper
The National Institute of Standards and Technology in Colorado created an atomic clock so correct they declare will neither achieve nor lose a second in 20 million years. It’s referred to as the NIST-F1 Cesium Fountain Clock and will get its accuracy from a fountain-like atomic motion.
