Can you reduce this to a smaller version of the same problem plus a stopping case — and does it look similar as you zoom in?
This is a reasoning lens, not ownership: the concepts belong to their disciplines, not to the model.

What am I looking at?
In this lens (6)
- Each term is defined from the two before it — a recurrence relation.
- Solves a problem through its recursive subproblem structure, caching results.
- Emerges from the self-referential Fibonacci recurrence.
- A process defined in terms of itself — the pattern itself.
- Applying a function to its own output builds self-referential structure.

Concept collections
Concept collections are curated lenses onto the fabric — themed sets of ideas that recur across disciplines. They are not journeys; they are a way to read the graph.
Understanding Systems
Stocks, flows and feedback — why wholes behave in ways their parts do not.
Patterns Everywhere
Regularities that recur across maths, music, nature and art.
How Information Moves
Encoding, signals and noise — the same idea in computers, genes and nerves.
About this view
What this is
Start from one concept and expand outward. The view never shows everything at once — click a node to refocus, filter by relationship type, or switch to an accessible list.
One fabric
3750 concepts and 5051 typed relations form one connected component — no isolated silo.
How to read it
Focus a concept, or apply a lens (discipline, mental model, journey) to see only the threads that matter.
