I remember reading in a book years ago about how one particular synesthete experiences the number pi. I’m not looking it up because it’s the memory that’s relevant here; it’s the memory that I’ve been working with in this week’s writing.
I remember it like this: to him, pi is less a series of individual digits written on a mental chalkboard than it is the line of infinitely long and varied curve, the edge of a rolling hill stretching across the horizon. He needs only to zoom in on a part of the line to see the microcurves that intimate the digits themselves. The way I see this in my head, this description, it’s less a mere unpinch zoom and much more fractal and plenoptic, more the way your eye can hone in on something without losing the whole, the way that detail is suddenly there, and not only that, it’s ALWAYS been there.
