Parts and the Material layer link to these scales; Python uses a dict that mirrors this table. --- ## Registry (typical L in meters) | Scale name | typical_L (m) | Knowledge / note | |:---|:---|:---| | Planck | \(1.616255 \times 10^{-35}\) | [[../knowledge/The Planck scale and the substrate's minimal resolution]] | | Quark / strong | \(1 \times 10^{-18}\) | QCD confinement; [[../Relational Friction]] | | Hadron / nuclear | \(1 \times 10^{-15}\) | Nuclear / fm scale | | Atomic / Bohr | \(5.29177210903 \times 10^{-11}\) | Bohr radius; fine-structure scale | | Molecular | \(1 \times 10^{-9}\) | [[../../expanded theory applied/further applications/Grand Map/Grand Map (RST)]] (L_MOLECULE) | | Cell | \(1 \times 10^{-5}\) | Grand Map (L_CELL) | | Organism | \(1\) | Grand Map (L_ORGANISM) | For the **unified chain** (Planck → molecule), scripts use the ordered list: planck, quark, hadron, atom, molecule (and optionally cell, organism), with the L values above. Same ordering as in [[Parts index]]. **Single source of truth:** The registry is **built from the individual part notes**. Each part note (e.g. [[Quark]], [[Hadron]], [[Atom]], [[Molecule]], [[Planck]], [[Cell]], [[Organism]]) has a machine-readable block: ```scale_part L 1e-18 ``` The engine scans `expanded theory/parts/*.md` for ` ```scale_part ` blocks, collects (part_id, L) where part_id = note name (lowercase), sorts by L (finest → coarsest), and uses that as the scale registry. **To add a new part** (e.g. Quantum): create a new note in parts with a ` ```scale_part ` block; no need to edit a central list. The file `config/scale_registry.json` is **generated** from these part notes when the engine runs. The table above is for human reference. --- ## Links - **Parts index:** [[Parts index]] - **Material layer translation:** [[../../expanded theory applied/further applications/Material layer/Material layer (RST)#V.
