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.
System context
Aerodynamicsis aFluid dynamicsEstablished
Aerodynamics is fluid dynamics of air.
Mechanism: It applies the flow equations to air moving over a wing, where a pressure difference creates lift.
Bernoulli's principleis part ofFluid dynamicsEstablished
Bernoulli's principle is part of fluid dynamics.
Mechanism: Bernoulli's principle is a key law of fluid dynamics: within a flow, faster-moving fluid exerts lower pressure — the effect that lifts a wing.

Turbulenceis part ofFluid dynamicsEstablished
Turbulence is a fluid-dynamics regime.
Mechanism: Above a critical speed a flow breaks into chaotic eddies that mix strongly and resist prediction.
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 · 5 of 5 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 5 → 21 → 46 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
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
