Centers do not imply edges; edges are often resentful and attempt to impose themselves, or to fool others into imposing them. But centers, too, are deceptive, boldly presenting themselves as absolutes when all is merely diffuse.

Most honest of all are points; but points are difficult to see. Points are not inclined to group into lines, as mathematicians once thought; rather, their natural tendency is towards puffy dispersion (the so-called ``dandelion-fuzz'' model); points would rather blow away on the wind. Points do exist, but lines and curves are man-made constructs. Put no trust in them.

A priori, the most basic geometric construct is arguably the radiation symbol. Although none are found in nature ...
