On neutrinos and nanoseconds: Physicists partner with professional timekeeper

In his job, Matsakis keeps the official time for the United States and the U.S. Department of Defense and, together with the National Institute of Standards and Technology, keeps the official time for the United States. This involves maintaining more than 100 atomic clocks and GPS systems calibrated to within one nanosecond of each other – not a simple task.

We had a nice seminar on what MINOS does and neutrino oscillations recently, as we kicked off this collaboration.
