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.
Every ham radio shack needs a clock; ideally one with operator-friendly features like multiple time zones and more. [cburns42] found that most solutions relied too much on an internet connection ...
Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise global time standard. The new optical clock is so accurate that it loses or ...
