an inquiry into branching systems
On the conjugation of trees and traces
The naturalist who walks long enough through a winter forest comes, eventually, to a quiet conclusion: the bare branches of an oak and the etched copper of a printed circuit are the same drawing, made by different hands. Both diagrams solve the same problem -- how to deliver something from one node to many -- and both arrive at the same answer.
We collect, in this folio, the slow correspondences. Where the dendrite forks, the trace forks. Where the leaf vein narrows, the conductor narrows. Where the river delta loses itself in the marsh, the silver of the antenna loses itself in the air. The map of one becomes, with patience, the map of the other.
Every entry that follows is annotated by hand and cross-referenced by lamp. We make no claims and offer no products. The reader is invited only to look.
An index of correspondences
Each entry below names a structure first observed in nature, then traced through the schematics of human invention. The pairing is not metaphor; it is geometry.
-
i.
Dendrite
The branched extension of a neuron, gathering signals at its leaves. Cf. the input pin-out of an analog summing amplifier.
-
ii.
Xylem
The vascular tissue that carries water upward against gravity. Cf. the rising bus on a memory backplane.
-
iii.
Mycelium
The hidden lacework of fungus connecting roots beneath the forest floor. Cf. the gossip protocol of a peer-to-peer mesh.
-
iv.
Delta
The fan of channels by which a river surrenders to the sea. Cf. the output stage of a multiplexed transmitter.
-
v.
Lichtenberg
The branching scar left by lightning on the body of a tree. Cf. the dielectric breakdown traced through cured resin.
-
vi.
Capillary
The narrowing vessel where blood and tissue exchange in silence. Cf. the trace narrowed to its impedance, where current settles.
-
vii.
Coral
The calcified record of a colony's slow geometry. Cf. the sintered architecture of a printed lattice.
-
viii.
Branch
The first answer offered to the question of how to reach further. Cf. the branch instruction, which permits a program to climb.
Annotations toward a quiet thesis
The reader will note that the page has been written in twice. The first hand, in upright Garamond, sets the argument; the second, in the right margin, makes the argument doubt itself. Both are necessary. The page that does not argue with itself is rarely a page worth keeping, and the same may be said of any sufficiently honest circuit.
Some marginalia survive only because the binder cropped less aggressively than expected. We have tried, in this volume, to leave the margin wide. It is in the margin that the phosphor lamp warms the corner of the desk and that small drawings of branching things accumulate, asterisk by asterisk, into a private taxonomy.
Where the body of the text speaks of trees and circuits as parallel, the marginalia confess that the parallel is not symmetric. A tree can be unplugged from its sun for an evening and remain a tree. A circuit without current is only the diagram of a circuit. The tree carries its own potential; the circuit borrows.
And yet, in the long view, both are temporary arrangements of carbon and copper for the routing of small disturbances. Both will eventually fall, be pruned, be replaced, be remembered as a sketch. Neither needs the reader's pity. Each does its branching while it is here, and that is the entirety of the project.
