How can a nucleus make a sound?

  1. Jun 12, 2012 #1
    This is from Paul Davies the Last Three Minutes

    I thought sound is due to particles moving up and down which activate hairs inside our ear which our immaterial, nonphysical, unconscious mind converts into meaning and communicates that meaning to the conscious mind. I don't see how the movement of one nucleus could create a sound. The only out I see is if that nucleus then causes other nuclei to move which is ultimately detected by the crystal lattice.

    Here, "sound" simply means lattice vibrations.

    Of course, if the crystal is in air, that vibration of the crystal lattice can cause molecules of air to vibrate- thus, causing sound waves in the air.
