The Atomic Clock

The atomic clock's oscillator isn't an object at all, but a beam of light. When the beam is tuned perfectly, that lone electron jumps in resonance and counting off,. 9,192,631,770 crests in that flickering light gives you exactly one second. We probe for the resonance of the crystalline spheres, listen for the soundless celestial music. The atomic clock is the closest we can get to the heartbeat of the divine. There's a great deal of beauty as well as terror in that definition.
