## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [outside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-outside.spatial), [part](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-part.relation), [range](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-range.spatial)

**Through:** The condition of a thing defines a range within which it persists; when an event occurs from outside that range, it causes a change that ends the thing even though its parts continue.

**Novel properties:**
- sudden termination from beyond bounds
- persistence of parts after whole ends
- spatial trespass enabling change

## Examples
- In the 2003 invasion of Iraq, U.S. supply convoys were ambushed near Nasiriyah by insurgents outside the expected combat zone. *(military)*
- The 1996 Mount Everest disaster began when climbers were ambushed by a sudden storm above the safe weather window. *(expedition)*
- In 2017, the NotPetya malware ambushed global shipping systems by exploiting a software update beyond normal network boundaries. *(computing)*
