zettel

Table of Contents

basic component of zettelkasten. A zettel is formulated in the following 3 parts:

unique ID
used to reference a specific zettel in other zettel
content
an idea, a thought.
reference
context, or source.

A functional zettel cannot just be your whole notebook with a unique ID like “notes-in-2024”. For a zettel to be functional in a zettelkasten, it has to follow some principles:

Backlinks

zettel should be atomic

content of a zettel should only address atomic idea, because:

In practice, when made atomic, a zettel often falls in one of 3 common zettel categories

  • use reference only if necessary
  • use only the plainest, most literal terms

    “I couldn’t reduce it to the freshman level. That means we really don’t understand it.” - Richard Feynman

navigation zettel

zettel that have lots of links. Could be specially made as entrance to ideas around a topic, like “Artificial Intelligence” to hold link to “Learning is not necessary for Artificial Intelligence”, when I have a good idea on the latter, and the former only as portal to good ideas like the latter.

This is an exception for zettel should be atomic. Clearly, “Artificial intelligence” can be split in many ways; yet this navigation is still useful

navigation zettels often falls into the following categories:

  • plain navigation for browsing - index
  • incidentally important concept - zettel
  • in the process of decomposing a complex problem - “solving XXX with A and B” “convert XXX into YYY” “solve YYY with A to B-compatible form” until the most simple propositions.
  • compilation of ideas to teach/present (draft/post of tutorial or artical) - “developmental learning tutorial 1: implementing scholarly thinking” “how one actually find out about useful knowledge from raw experience”

creative understanding

(primitives)

common and and intuitive way is to do discussion of this idea: writing definitions, proofs, tutorials, illustrations, teach it to someone else etc.

Another way of looking at it is to see the whole paper as a polished compilation zettel, copying each reference into the main text, then it is intuitive to recreate it with bunch of zettels

common zettel categories

In practice, atomic zettel often falls in one of the following category:

  • A can xxx B, A is C to B, A have property B (relationship of A and B; Proposition involving A and B)
  • A (definition of A)
  • Implementing A in C (implementation of an idea A with environment C)

zettelkasten

zettelkasten is note-taking and note management system with the following 4 properties:

  • notes are managed as bag of individual zettel(instead of hierarchies)
  • individual notes are atomic and short
  • individual notes have unique identifier
  • individual notes are connected with reference relation by quoting the unique identifier
