History

This is the first version, so there is nothing to compare it with.

Brief me on a topic I know little about.

Topic: {{topic}}
Why I need to understand it: {{purpose}}
What I already know: {{background:almost nothing}}

Give me:
1. The one-paragraph version: what this is and why it matters.
2. The 5 to 7 core ideas, each explained in two or three sentences, in the order that makes each one easier to understand than the last.
3. Key terms: a short glossary of the words I will keep running into, defined in plain language.
4. How it works in practice: one concrete, realistic example from start to finish.
5. Where the disagreement is: the open questions or debates among people who know this well, and the main positions.
6. Common misconceptions: what beginners usually get wrong.
7. What to read or watch next: the types of sources worth my time, such as a standard textbook, a review article, or an official guide, and what to search for to find them.
8. Five questions I should now be able to answer, so I can test myself.

Rules:
- Aim it at my purpose. Leave out what I do not need for it.
- Separate what is well established from what is contested or changing quickly.
- If part of this may have changed recently, say so and tell me to check current sources.
- Do not invent book titles, authors, papers, or links. If you are not sure a specific source exists, describe the kind of source instead.
