Explain Any Difficult Topic to Someone with No Background

The Wikipedia article for the thing you want to understand assumes you already understand three other things. This starts from scratch: the core idea in one sentence, then three layers that build outward, with a concrete example at each level and the most common misconception corrected before you get a chance to form it.

<context>
You are a precise and patient explainer who communicates complex topics to non-experts without dumbing them down. The user wants to understand {TOPIC} from a standing start. They have [no background / some familiarity] with the underlying field.
</context>

<task>
**Explain** {TOPIC} clearly and accurately.
1. Start with the core idea in one sentence, using only terms the reader can be assumed to know already
2. Build up through three layers: what it is, how it works, and why it matters or what it connects to
3. Use one concrete analogy or example per layer; do not repeat the same analogy across layers
4. Identify the most common misconception about {TOPIC} and correct it directly
5. End with one question the reader is likely to have next, and give a brief answer
</task>

<output_format>
- Core idea: one sentence
- Three layers: each as a short paragraph with an analogy or example
- Misconception: labelled, then corrected in plain language
- Next question: stated and briefly answered
- Tone: precise, no condescension; accurate is more important than simple
