- Computed level: L5 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: emergence  ·  Arena: double.quantity

## Emergence
**Emerges from:** [make](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-make.verb), [copy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-copy.replication), [first](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-first.order), [second](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-second.temporal)

**Through:** make and copy together produce a second instance of something

**Novel properties:**
- dual occurrence
- ordinal repetition
- temporal pairing

## Examples
- The Large Hadron Collider produces a second Higgs boson in 2016, four years after the first detection in 2012. *(physics)*
- A northern white rhino cell line was cloned in 2020, making the second living individual from the subspecies. *(biology)*
- The 2011 Fukushima reactor cooling system failed to double its backup pumps before the tsunami hit. *(engineering)*
