The urge to reduce the seemingly infinite variety and complexity of the visible world to some aesthetically satisfactory order has been a part of man's intellectual life since ancient times. In ancient philosophy and in modern science the natural orientation of this drive has been in the direction of understanding this variety and complexity as the natural outcome of the enormous number of combinatorial possibilities available to even a small number of basic entities subject to fixed laws of behavior. The search for these basic entities and for the strict formulation of the laws which govern them is still very much the essential fabric of physics today.
