Polish physicists have been aiming to build an optical atomic clock, an extremely precise device with an accuracy of one second in a few dozen billion years, since 2008. The last of the three key components of the clock: an atomic frequency standard based on cold strontium atoms has just been developed. The clock itself will be assembled already this year.
