Reading helps me acquire understanding; writing gives me a way to speak to the world. Yet finishing a book does not mean I can use what it contains when I need it.
At some point, I began asking: Who am I? Where do I want to go? What do I want to do? Answering those questions requires looking at myself and the world together. I had long treated learning mainly as an assigned task. Later, I returned to reading, explored knowledge management, and began trying to write.
Dense nonfiction could feel like a storehouse of valuable material that I did not know how to carry away. Memory alone retained too little.
Inspired by Niklas Luhmann’s slip-box approach, I developed a classification suited to my own reading and writing: concepts, facts, people, stories, methods, models, quotations, and counterintuitive ideas. I call it the Eight-Atom Method.
What the eight categories contain
| Type | What to record | A question to ask later |
|---|---|---|
| Concepts | Definitions, boundaries, and source locations | Do I understand this term accurately? |
| Facts | Data, events, dates, scope, and sources | What material supports this claim? |
| People | Relevant experiences, actions, and work | Why does this person matter to the question? |
| Stories | Setting, people, actions, process, and outcomes | How did this unfold? |
| Methods | The problem, steps, and conditions of use | When could I try this? |
| Models | Elements, relationships, assumptions, and necessary formulas | What does it explain or leave out? |
| Quotations | Accurate short quotations and their sources | What idea does this express concisely? |
| Counterintuitive ideas | A common view, an alternative, and supporting material | Does the difference concern facts, conditions, or wording? |
The categories can overlap. A story can contain facts and illustrate a method. Classification should make material easier to find and use; it need not force every passage into a single box.
Making a note
Keep each note focused on one idea you can explain, with three parts:
- The material. Express it accurately in your own words and clearly mark any quotation.
- The source. Keep the book title, chapter, page, or another location that lets you recover the context.
- Your question. What uncertainty does it address? How might you use it? What remains unclear?
Biographical details, statistics, formulas, and quotations should be checked against their sources. That remains necessary when AI helps extract the material. Extraction does not establish accuracy or understanding.
Turning notes into writing
I think of the collection as an herbalist’s cabinet: each type of material has a place, ready to be selected when needed. But a cabinet cannot prescribe a remedy. Classification alone does not produce an essay.
Start writing with a question. Use concepts to establish what is being discussed, facts and stories to explain the situation, methods and models to organize an answer, and your own judgment to state a position. There is no need to use all eight categories in every piece.
At a broader level, I can review an essay through four questions: What are the concepts? What are the facts? What actions are possible? What do I think? The eight categories help me move between these layers.
Start with a short passage
Choose one small section of a nonfiction book and make no more than three useful notes. Then write a short response to a current question without simply copying those notes.
If the notes do not help you understand, act, or explain, check whether they preserve only attractive language without a clear meaning or use.
The method earns its place when I can retrieve material, understand it in context, and use it to form an answer of my own.
