Top-precision optical atomic clock starts ticking

A state-of-the-art optical atomic clock, collaboratively developed by scientists from the University of Warsaw, Jagiellonian University, and Nicolaus Copernicus University, is now "ticking away" at the National Laboratory of Atomic, Molecular and Optical Physics in Toruń, Poland. As the first of its kind in Poland and one of just a handful of clocks of this caliber in the world, the new clock will keep track of the passage of time with extraordinary precision.
