## How the H-Index Works
A researcher has an h-index of h if h of their papers have each been cited at least h times.
### Estimation
An approximate h-index can be estimated as:
**h ≈ floor(sqrt(Total Citations))**
This approximation (Hirsch's original heuristic) works well for typical citation distributions. The exact h-index requires sorting papers by citation count.
### Context
- Early career: h = 5-10
- Mid career: h = 15-30
- Senior researcher: h = 30-60
- Field leaders: h = 60+

计算示例
A researcher has 50 publications with 800 total citations.
- Average citations: 800 / 50 = 16.0 per paper
- H-index estimate: floor(sqrt(800)) = floor(28.3) = 28
