We must love them both—those whose opinions we share, those whose opinions we don't share. They've both labored in the search for truth and have helped us in finding it.
~ St. Thomas Aquinas
On a desolate island off the west coast of Scotland, the sand "sings" when it’s touched. Walking across the beach produces a wide range of musical tones, like playing a musical instrument.
Scientists think the structure of the sand creates the sounds. The grains of sand are tiny pieces of quartz, rounded by the sea. Each grain is surrounded by a pocket of air. When the sand is touched, friction between the air and the grains produces musical tones. We may not have a chance to hear the strange music of singing sand, but we all have a chance to hear the music of rustling leaves. Happiness need not be pursued in exotic places. The joyful music of Creation surrounds us. All we need to do is listen.
