About Narsil

The model is Asimov's Encyclopedia Galactica — a single compendium meant to preserve and compress the knowledge of a civilization. But a static encyclopedia decays as fast as the world changes. Narsil aims instead to be living: a structure that doesn't just hold knowledge but reasons over it — deriving what follows, simulating what moves, and pointing to what is still missing.

The wager is simple. If every field is encoded in the same underlying structure, then the walls between disciplines become passable, contradictions become visible, and the whole becomes more than the sum of its notes. That movement — from scattered to structured, from many tongues to one — is the work. Call it negentropy: order, deliberately imposed on the heap.

Everything is organized three levels deep:

1. Domain — one of five great branches of knowledge
2. Field — a discipline within a domain (Mathematics within the Formal Sciences)
3. Note — a single topic, seen through all six modes of knowing at once

There is no single way to know a thing. Across history, civilizations have answered "what does it mean to know?" in six distinct ways — and Narsil refracts every field through all six. The same idea becomes a different object in each lens:

1. Forms — its essence: the irreducible elements and ideal forms (Pythagoras · Plato · Aristotle)
2. Deductive — what follows necessarily from axioms and definitions (Euclid)
3. Experimental — what can be measured, and what causes what (Bacon · Galileo)
4. Algorithmic — the effective procedure: inputs, steps, outputs (al-Khwarizmi · Turing)
5. Systematic — stocks, flows, feedback loops, and equilibria (Wiener · Forrester)
6. Engineering — control and optimization under constraint (the designers)

Together they form a kind of spectroscope for ideas: pass any topic through them and its full structure separates out.

What makes the encyclopedia dynamic is that the six modes are not only prose for a reader — each note stores the same structure as typed, machine-readable atoms: entities and the relations between them. Because the whole atlas shares one schema, it can operate on itself:

• Construct takes those relations as premises and deduces what necessarily follows — or proves an equation outright.
• Simulate assembles a field's dynamics into a living system you can perturb and watch settle.
• Explore turns the graph into a walkable memory palace, in 3D and VR.
• A gap engine reads what each field should contain and flags what is missing — the negative space where knowledge has yet to be ordered.

The prose is for you. The structure is for the machine. Both describe the same thing.
