## Emergence
**Emerges from:** [control](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-control.ability), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [device](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-device.tool), [make](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-make.verb)

**Through:** a control acts through a device to make a change, organizing the components into a directed transformation.

**Novel properties:**
- directed change
- functional agency
- controlled outcome

## Examples
- The Hubble Space Telescope corrected its blurred vision in 1993 when astronauts installed COSTAR, a device that redirected light properly. *(engineering)*
- In 2015, Volkswagen altered emissions software in 11 million cars to change behavior during testing cycles. *(computing)*
