# proportion (relation)

the relation among several parameters that keeps all of their windows open at once

- Computed level: L18 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: emergence

## Emergence
**Emerges from:** [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [keep](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-keep.maintenance), [several](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-several.quantity), [open](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-open.spatial), [relation](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-relation.association), [once](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-once.temporal)

**Through:** The components interact as multiple parameters maintain their respective ranges open through continuous adjustment despite aimless drift.

**Novel properties:**
- sustained co-availability
- temporally unified openness
- dynamic range coordination

## Examples
- The U.S. Standard Gauge of 4 feet 8.5 inches links compatible rail networks across 25,000 miles of track, enabling continuous freight movement. *(engineering)*
- In 2020, the International Space Station maintained a breathable atmosphere by balancing O₂, CO₂, and pressure levels across all modules. *(physics)*
- The Federal Reserve adjusts interest rates in response to inflation and unemployment, keeping both within target windows since 1977. *(economics)*
