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
ConvectioncausesHeat transferEstablished
convection causes heat transfer.
Mechanism: Convection moves heat by moving matter: heated fluid becomes less dense, rises, and carries its warmth to a cooler region.

Heat transferdepends onFluid mechanicsEstablished
Heat transfer depends on Fluid mechanics.
Heat transferdepends onTemperatureEstablished
heat transfer depends on Temperature.
Mechanism: Heat flows spontaneously from higher to lower temperature until the two reach thermal equilibrium.

System context
Convectionis part ofHeat transferEstablished
convection is part of heat transfer.
Mechanism: Convection is one mode of heat transfer: warm fluid rises and cool fluid sinks, carrying heat as the material itself moves.

Thermal conductionis part ofHeat transferEstablished
thermal conduction is part of heat transfer.
Mechanism: Conduction is heat transfer through direct contact: fast-jiggling particles pass their energy to neighbouring slower ones.

Thermal radiationis part ofHeat transferEstablished
thermal radiation is part of heat transfer.
Mechanism: Radiation is heat transfer without a medium: any warm object emits infrared light that carries energy across empty space.

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 · 8 of 8 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 3 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 7 → 28 → 99 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 3 foundation relations. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
1 concept build on this directly, 1 in total, across 2 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.

Energy transformation
Energy is never created or destroyed; it changes from one form into another, and some is always lost as heat.
Follow the energy: where did it come from, what form is it in now, and where does it go next?
Entropy & irreversibility
Left alone, systems drift toward their most probable, most spread-out states — giving processes a direction in time that is hard to reverse.
Ask why a process only runs one way. Order can grow locally only by exporting more disorder elsewhere — and it always costs energy.
