## Emergence
**Emerges from:** [device](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-device.tool), [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [structure](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-structure.arrangement), [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), [flow](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-flow.movement), [make](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-make.verb), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity)

**Through:** Energy flows through a structured arrangement of parts, enabling controlled change that persists.

**Novel properties:**
- controlled transformation
- dynamic stability
- directed functionality

## Examples
- The LHC at CERN circulates protons at 6.5 TeV, guided by superconducting magnets in a 27-km ring. *(physics)*
- A beehive maintains a 35°C internal temperature despite external swings, using wing-fanned air flow. *(biology)*
- The Hoover Dam channels Colorado River water through turbines to generate 4.2 TWh yearly. *(engineering)*
