an atomic [[{4.1} a note is any artifact containing some point of data|note]] is one that holds a single self-contained thought (or "unit of knowledge", more broadly). this helps keep notes unambiguous and allows you to reference individual ideas that can be fruitful in [[{5.1a} idea sex|combinational creativity]]. i believe this term was popularized by [Andy Matuschak](https://notes.andymatuschak.org/z5E5QawiXCMbtNtupvxeoEX) as an extension of luhmann's [Zettelkasten method](https://zettelkasten.de/introduction/).
this is in contrast to running or outline notes based on theme, subject matter, or topic.
*for example*, you might have a single document for everything you learn about notetaking:
```
# notetaking
## why notetaking matters
- improves retention and supports critical thinking
- supports creativity
- keeps you from passively consuming
## types of notetaking systems
- outline / bullet-point notes
- atomic notes
- mind mapping
```
you might build on the outline over time, adding sub-points as you learn more about each topic or idea.
this same information split into atomic notes might look like:
```
# notetaking
- [[notetaking improves retention while supporting creativity and critial thinking]]
- [[active notetaking prevents passive consumption]]
- [[running outline notes]]
- [[atomic notes]]
- [[mind mapping]]
```
in this case, each linked item (`[[]]`) is its own document; instead of referencing a single `notetaking` file, i can reference files for different systems or benefits of notetaking, meaning i can re-use them throughout my vault even when i’m writing about a completely different topic.
atomic notes are beneficial in several ways, including:
- thinking through questions and finding connections between disparate ideas.
- writing, as your notes become the building blocks for longer output.
- seeing your thought process change and expand over time.
don’t stress over [[{4.1a1} when does something become an atomic note|when to make something an atomic note]]; note change, combine, and break apart over time anyway.
