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
Channel capacitydepends onBandwidthEstablished
Channel Capacity depends on Bandwidth.
Channel capacitydepends onShannon entropyEstablished
The limit of reliable rate.
Mechanism: Shannon's theorem sets channel capacity, the top speed of error-free communication over noise.
Channel capacitydepends onSignal-to-noise ratioEstablished
Channel Capacity depends on Signal-to-Noise Ratio.
Mechanism: Higher SNR raises the reliable data rate.
Enables · leads to
Error-correcting codedepends onChannel capacityEstablished
Redundancy beats noise.
Mechanism: Error-correcting codes reach the channel capacity by adding just enough structured redundancy.
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 · 4 of 4 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.
Structural neighbourhood: 4 → 15 → 60 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 4 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

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.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Shannon entropy, Signal-to-noise ratio and Error-correcting code.
Through this lens it connects to Signal-to-noise ratio, Bandwidth and Error-correcting code.
