All objects vibrate. It’s the nature of matter and energy. Even at the theoretically unattainable temperature of absolute zero, molecular motion would still exist. For better or for worse, we respond to frequencies. A sonic weapon can leave you disoriented or nauseous, as can an overamped bass beat at a show. Earthquakes can tear down the world around us, and an emotionally charged crowd can lift your team to triumph.
    Why does this happen? Sympathetic vibration. Sound, energy and emotions resonate from one object to another. Screamin Eagle pipes on a Harley rattle your brains, as does Ludwig van, just at a whole different frequency and amplitude. What will be your good vibrations?
