Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
RefractioncausesReflectionEstablished
refraction causes reflection.
Mechanism: At a boundary, refraction and reflection occur together: as light bends into a new medium, part of it also bounces back off the surface.

Mirrordepends onReflectionEstablished
mirror depends on reflection.
Mechanism: A mirror works by reflection: its smooth surface bounces every light ray in an orderly way, so it rebuilds a clear image.

Reverberationemerges fromReflectionEstablished
reverberation emerges from reflection.
Mechanism: Reverberation is the dense sum of countless sound reflections.

System context
Echois aReflectionEstablished
echo is a kind of reflection.
Mechanism: An echo is a discrete reflection returning after a perceptible delay.

Total internal reflectionis aReflectionEstablished
Open Total internal reflection →
Total internal reflection is a kind of reflection.
Mechanism: Total internal reflection is complete reflection: past a critical angle, light hitting a boundary from the denser side bounces entirely back instead of refracting.

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 · 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 7 → 23 → 85 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

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
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
