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
Rate of changedepends onLimitEstablished
Rate of change depends on limit.
Mechanism: The instantaneous rate of change depends on a limit: the derivative is the limit of the average change as the interval shrinks to a point.
- Wikipedia (English & German editions) verifiedmoderate evidence
LimitenablesRate of changeEstablished
limit enables Rate of change.
Mechanism: The derivative is defined as a limit: the slope over an interval as that interval shrinks toward zero.

Differential equationdepends onRate of changeEstablished
differential equation depends on Rate of change.
Mechanism: A differential equation relates a quantity to its own rate of change — the language of growth, motion and feedback.

Tangentdepends onRate of changeEstablished
tangent depends on Rate of change.
Mechanism: A tangent line's slope is the rate of change: the derivative at a point gives exactly the steepness of the line grazing the curve there.

System context
Accelerationis aRate of changeEstablished
acceleration is a kind of Rate of change.
Mechanism: Acceleration is the rate of change of velocity with time.
- University Physics (OpenStax) verifiedmoderate evidence
Flowis aRate of changeEstablished
A flow is a rate of change of a stock.
Mechanism: A flow is a rate of change: it is how fast a stock fills or drains, measured per unit of time.
Velocityis aRate of changeEstablished
velocity is a kind of Rate of change.
Mechanism: Velocity is the rate of change of position with time.

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 · 9 of 9 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 2 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 8 → 28 → 80 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 2 foundation relations. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
2 concepts build on this directly, 3 in total, across 5 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
