For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the basis for the definition of a second.
Now, a new challenger has emerged in the timekeeping arena. Researchers recently developed a tiny, MEMS-based clock that makes use of silicon doping to gain record stability. After running for eight hours, the clock only deviated by 102 nanoseconds, approaching the…
