## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [side](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-side.surface), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [flat](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-flat.commonsurfacegeometry), [marks](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-marks.visual), [piece](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-piece.portion), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [surface](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surface.exterior), [relevance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-relevance.core)

**Through:** Matter has two sides and a boundary, and patterns of marks are arranged on the surfaces through interaction.

**Novel properties:**
- bounded two-sided surface
- spatially uniform plane
- patterned visual field

## Examples
- The yellowing pages of the 1611 King James Bible first edition show ink patterns within bounded flat surfaces. *(history)*
- A4 sheets in the 2020 print run of 'The Guardian' newspaper carried typed marks on both sides, stacked in bundles. *(publishing)*
- The cracked clay tablet from Uruk, circa 3200 BCE, bears the earliest known cuneiform marks on a flat piece. *(archaeology)*
