On the geometric level, we see certain physical elements repeated endlessly, combined in an almost endless variety of combinations. . . It is puzzling to realize that the elements, which seem like elementary building blocks, keep varying, and are different every time that they occur. . . . If the elements are different every time that they occur, evidently then, it cannot be the elements themselves which are repeating in a building or town; these so-called elements cannot be the ultimate "atomic" constituents of space.
