## Emergence
**Emerges from:** [material](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-material.physical), [piece](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-piece.portion), [flat](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-flat.commonsurfacegeometry), [surface](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surface.exterior), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent)

**Through:** When a physical material is divided into a bounded portion and arranged with a flat exterior, it forms a coherent surface available for use.

**Novel properties:**
- usable surface area
- structural stability
- placement capacity

## Examples
- The International Space Station's solar array wings deploy rigid photovoltaic panels to power onboard systems. *(engineering)*
- The 1977 vinyl release of Elvis Presley's 'Moody Blue' played on a Technics SL-1200 turntable at Studio B in Nashville. *(everyday life)*
