Consider, for example, the following whimsical speculation about “scale,” knowing that, if marked on paper, and if viewed from an extreme vantage of distance, the period at the far end of this sentence might constitute a point of zero dimension; but as I magnify this dot of punctuation, the period soon becomes a circle, with two dimensions; and as I magnify the period even further, zooming into it, I see that the circle becomes a planar fabric of linear fibres, each of which, from afar, has one dimension; and as I magnify each strand further, I see that, eventually, it becomes a tubule, with three dimensions — leading me to conclude that the period at the far end of this sentence might, in fact, occupy a diverse variety of dimensions, each of which contradicts the others, depending upon the scale at which I might prefer to observe such a tiny mark after this last word.
