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

**Through:** Parts come into contact, initiating an event where change occurs.

**Novel properties:**
- sudden transition
- contact-triggered change
- discrete response

## Examples
- A ballpoint pen clicks shut when the spring-loaded mechanism locks the tip into place after pressing the button. *(engineering)*
- The Geiger counter clicks each time a radioactive particle ionizes gas in the tube, completing a circuit. *(physics)*
- A climber's carabiner clicks into the harness loop, securing the rope connection during ascent. *(everyday-life)*
