These are some interactive, reactive documents I wrote to help students understand some basic epidemiological/statistical calculations.

These documents make use of the excellent *tangle* and *D3*libraries.

\[
\left\{
\begin{split}
& \boldsymbol{\nabla} \cdot \boldsymbol{E} = \frac{\rho}{\varepsilon_0} \\
& \boldsymbol{\nabla} \cdot \boldsymbol{B} = 0 \\
& \boldsymbol{\nabla} \times \boldsymbol{E} = – \frac{\partial \boldsymbol{B}}{\partial t} \\
& \boldsymbol{\nabla} \times \boldsymbol{B} = \mu_0 \boldsymbol{J} + \varepsilon_0 \mu_0 \frac{\partial \boldsymbol{E}}{\partial t}
\end{split}
\right.
