Resonance
Interaction events tell us what became active at a moment. coupling records which parts of the substrate repeatedly became active together. Resonance names the next relation: structural overlap that remains coupled through use within a chosen time window.
Resonance is what lets local events become a region we can follow. A single encounter may be incidental. Repeated encounters among related frames and actors begin to hold a recognizable configuration in place, even while its contents continue to change.
Resonance does not mean agreement. Contradiction, negotiation, and mutual constraint can keep a region active just as reinforcement can. The signal is that the parts continue to matter to one another through the shared medium.
From events to membranes
The concepts form a sequence:
- Interaction events show what actors read, use, revise, or write.
- Coupling retains the history of what repeatedly becomes active together.
- Resonance identifies coupled structure that continues to hold together at a chosen grain and over a chosen interval.
- A connected resonant region forms a membrane: a boundary we can observe across time.
This sequence is how the Lab moves from individual actions to collective dynamics without assuming a collective actor in advance. We can ask whether a region persists, reorganizes, splits, or dissolves, and whether treating it as a unit explains more than looking at its members separately.
Resonance depends on scale and time. A configuration that holds for one task may disappear across a longer interval; a coherent region at project scale may contain several conflicting regions when viewed more closely. Declaring that grain is part of the observation.
