We think of atomic clocks as the definitive timekeepers. They are famous for being accurate down to the picosecond.
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
