The reading-time estimate is $t = \lceil w / 200 \rceil$ minutes, where $w$ is the word count.

$$\text{cosine similarity} = \frac{A \cdot B}{\lVert A \rVert \, \lVert B \rVert}$$

The graph view lays out notes with a force-directed simulation:

$$F_{ij} = k \frac{q_i q_j}{r_{ij}^2} \qquad \text{(repulsion between unconnected nodes } i, j\text{)}$$

$$\sum_{i=1}^{n} \left( x_i - \bar{x} \right)^2 = \text{variance} \times n$$
