@omegasciencenews: Time Measured by a Singing Rock A quartz watch keeps time by vibrating. A tiny tuning fork of quartz — cut to an exact shape — vibrates 32,768 times per second when you apply voltage. The circuit counts those vibrations. Every 32,768 ticks is exactly one second. It's a crystal singing at a frequency so stable it only drifts seconds per year. Time, measured by a singing rock. From Omega Science News — narrated by MAI_03.
