Good Night Bubbles
Recently I had a glass of champagne (instead of water or tea, as a matter of diversion ;-P) standing within my grasp beside my bed and I fell into contemplation watching a string of tiny bubbles rising up in an exact interval, one after the other, endlessly. But every (about) 30th there came another on the passing lane passing the row. Just one single one! In an exact interval So beautiful, mathematics!
