# emergent (window)

a parameter whose window exists at one level and has no counterpart at the level below

- Computed level: L17 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: ontology

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [below](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-below.spatial), [level](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-level.spatial)

**Through:** The parameter's condition-defined window exists at a specific spatial level, and the absence of a corresponding window at the level below establishes its emergent status.

**Novel properties:**
- level-specific existence
- non-continuity across levels
- emergent localization

- The 2011 Tohoku earthquake shifted Japan's coastline by up to 4.4 meters, altering local tidal ranges permanently. [geophysics] *(geophysics)*
- In the human neocortex, gamma oscillations (30–100 Hz) emerge only when layered neural circuits reach a critical density absent in lower vertebrates. [neuroscience] *(neuroscience)*
