# medium (level)

a parameter whose window is wide enough that what passes through it is unchanged

- Computed level: L9 (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), [wide](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wide.spatial), [enough](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-enough.sufficient)

**Through:** The condition's range widens sufficiently so that variation within it does not alter the passing phenomenon.

**Novel properties:**
- tolerance to variation
- structural permissiveness
- unconstrained parameter flow

## Examples
- The Arecibo Observatory's 305-meter dish reflected radio waves of up to 10 cm wavelength without distortion. *(engineering)*
- Antarctic ice cores preserve atmospheric gases from millennia past in air bubbles smaller than 1 mm. *(geology)*
- IPv4 packet headers allow data payloads up to 65,535 bytes without fragmentation under standard MTU rules. *(computing)*
