- Computed level: L4 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: interaction.process  ·  Arena: interacting

## Emergence
**Emerges from:** [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [touch](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-touch.together), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension)

**Through:** two things change each other and are in contact, producing interaction

**Novel properties:**
- mutual change
- contact-dependent interaction
- temporal sequence

## Examples
- In 2012, two billiard balls collided on a felt table at 2.3 m/s, exchanging momentum and altering trajectories. *(physics)*
- Every 90 minutes, circadian pacemaker neurons in the human suprachiasmatic nucleus adjust each other's firing rates through synaptic contact. *(biology)*
- During the 2008 financial crisis, banks' interlocking credit default swaps amplified losses across institutions through direct contractual links. *(economics)*
