# resilience (recovery-rate)

The rate at which a parameter returns inside its window after being pushed outside.

- Computed level: L15 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: emergent

## 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), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [inside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-inside.spatial), [outside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-outside.spatial), [return](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-return.movement), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [rating](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-rating.evaluation)

**Through:** The interplay of aimless drift, boundary limits, and movement back in time from outside to inside the allowable range determines how quickly a parameter returns to normal.

**Novel properties:**
- speed of return
- evaluated rate
- dynamic stabilization

## Examples
- The Fukushima nuclear reactor cooling system failed to return to safe temperature range after the 2011 tsunami, leading to meltdowns. *(engineering)*
- After the 1929 stock market crash, the Dow Jones took 25 years to regain its pre-crash peak value. *(economics)*
- A human body typically restores blood glucose levels to normal range within two hours after a meal. *(biology)*
