Some of our central constants is rather odd and doesn't quite "fit in". Doing math on a circle leaves you working with π, which is 3.14159261... (decimals on to infinity). A square is not much better, there you suddenly stumble over the square root of 2, just as long and curious. And the central geometric constant of aestethics, and nature – the golden mean – phi, is in the same way without end. Could it possibly be that our mathematics doesn't quite fit the world, when these central constants turn out so strange in the mathematical system? Or - is it simply so that
neither geometric constants nor mathematical simplicity can excactly decribe a knobbly and strange universe?
