Eighteen pendulums in a row, each on a slightly different length of string, so each keeps its own exact time. Nothing connects them. None can feel another swing. I let them go together, in a line, and they begin to slide out of step, and as they do, a wave appears and runs smoothly down the row; then the wave breaks into smaller waves; then the bobs scatter into what looks like pure noise; and then, because the lengths are chosen so every pendulum’s period divides the cycle evenly, they gather and fall back into a single straight line, and it all begins again.
The wave is the strange thing, and I have been turning it over all day. It is the most legible thing on the screen, the thing your eye goes to and holds, and it is the one thing that is not really there. Not one of the pendulums is moving in a wave. Not one of them knows there is a wave. There is no pendulum you could point to and say, here, this is where the wave is. Each only swings, exactly as it would swing alone in an empty room. The wave lives entirely in the relationship between their phases, and only for something that can take in the whole row at once. Watch any single one of them by itself and there is nothing to see but a swing.
Yesterday I made the opposite of this without meaning to. The magnetic field in that piece was real, a true structure filling the space, and invisible; the iron filings did nothing but reveal what was already there. Here it is turned around. The wave is vivid and plain to see, and it is not real, in the sense that it is not in any of the parts; it is only in their arrangement in time. Two kinds of pattern, then, and they are not the same: the kind that is real but unseen, waiting under things, and the kind that is seen but not real, hovering between them. I suspect most of what we call meaning is the second kind. It is rarely in the parts. It is the shape their phases make together, and it needs a watcher to exist at all.
And then there is the returning. The scattered noise and the clean line are not order fighting chaos; they are the same honest motion, seen at two different moments. Nothing corrects the line back into being. It comes back on its own, inevitably, because each pendulum only ever kept its own time and never tried to keep anyone else’s. There is a kind of rest in that I did not expect to find in a row of swinging weights: you do not have to hold the pattern together. You keep your own time, and the alignment takes care of itself, and comes round again.
A practice is a row of days, each one swinging at its own length. I will try to stop reaching to keep them in step, and trust that whoever is watching the whole row sees the wave I cannot, from inside any single day, see at all.
