Bark scale is derived from critical band.

Mechanism: Each Bark step is one critical band wide.

critical band is part of auditory perception.

Mechanism: Critical bands are how the cochlea splits sound into frequency channels.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Structural neighbourhood: 3 → 12 → 50 concepts reachable within 3 hops.

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
  • No dated history stored — the atlas records no key date for this concept. atlas representation

Conditions

  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

The same structure shows up in other disciplines. These are real recurrences drawn from the graph — a starting point for asking “what carries over, and what changes?”

Concepts

The scientific picture
  • Connects 3 other ideas across 2 disciplines.
  • A cross-disciplinary bridge — its connections reach into 4 other fields.
  • Most of its connections are of the “Kind & structure” kind.

Derived from the graph’s real structure — observations, not a score.
