   11 lut 2016 · Physicists in Germany have built the most accurate timepiece on Earth, achieving unprecedented levels of accuracy with a new atomic clock that keeps time according to the movements of ytterbium ions. Called an optical single-ion clock, the device works by measuring the vibrational frequency of ytterbium ions as they oscillate back and forth ...
