Please allow me to draw you a picture of a very small world. I want you to hold up your hand and imagine it a bowl made of clay. Open your fingers a little and see how the years have worn away at the rim. Cracks and chips produce a very irregular pattern. Now fill half of the bowl with sand and dip the opposite side into some water. As the water seeps threw the cracks and begins to swirl in the sand, filling this small world; look around it anew, and see as I do....
