| description | LandauGraph — reasoning-constrained skill graph distilled from Landau-Lifshitz 10-volume Course of Theoretical Physics. 97 nodes, 196 edges. 4 edge types: prerequisite, reasoning-instance, abstraction, analogy. Production graph for agent physics reasoning. |
| unit_system | Gaussian |
| unit_note | All formulas in this skill use GAUSSIAN (CGS) units, following Landau-Lifshitz. Maxwell: ∇·E=4πρ, ∇×B=(4π/c)J+(1/c)∂E/∂t. Coulomb: F=q₁q₂/r². Lorentz force: F=q(E+v×B/c). No ε₀ or μ₀ appears. For SI conversion, load the `si-gaussian-conversion` skill.

LandauGraph — Landau-Lifshitz Reasoning Graph
A reasoning-constrained skill graph distilled from the complete 10-volume
Landau-Lifshitz Course of Theoretical Physics. This is the PRODUCTION GRAPH
— the output of the discipline-distillation methodology.
Graph Structure
- 97 nodes: ~38 reasoning templates + ~59 knowledge nodes
- 196 edges: prerequisite, reasoning-instance, analogy, abstraction
- 3 hidden parent nodes: symmetry_drives_physics, timescale_hierarchy, causality_as_constraint
- 4 edge types: prerequisite, reasoning-instance, abstraction, analogy

How to Use
Retrieval
Load GRAPH.json to get the full topology. For each node, read
nodes/{node_id}.md for the complete content (Core Picture, Algorithm,
Edge Cases, Cross-References).
Node Types
- reasoning.*.md: Reasoning templates with trigger conditions, algorithms,
edge cases, and cross-references. Designed for agent retrieval.
- knowledge.*.md: Reference knowledge — formulas, definitions, parameter
ranges. Anchored to Landau sections.
Edge Types
- prerequisite: Node B requires Node A (logical dependency)
- reasoning-instance: Knowledge node is a concrete instance of a reasoning pattern
- abstraction: Node abstracts a pattern from multiple instances
- analogy: Non-identical but structurally similar reasoning

Methodology
This graph was produced by the discipline-distillation methodology
(three-track extraction, systematic rumination, blind-derivation validation).
For the complete distillation history — rumination reports, rewrite fixes,
and validation experiment results — see:
