Scientists on Fermilab's Muon g-2 experiment are using a finely tuned clock to precisely measure how fast the muon — a heavy cousin of the electron — precesses, or wobbles, in the presence of a magnetic field.
To remove subconscious bias from the experiment's measurements, in March 2018, two Fermilab scientists outside the Muon g-2 collaboration set the clock to a certain frequency. For the period that Muon g-2 is taking data, only they will know that setting. This bias-removal technique is called clock blinding.
