In this case, the new clock uses an ion of aluminum linked to an ion of magnesium, forming what is known as a quantum logic clock. In this, the aluminum ion has a high-frequency, stable "tick." ...
Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...
