more introduction. Explanation of polarization? Transmission of originally unpolarized light through two polarizers?  Light intensity $I$ after passing through two polarizers at angles $\theta_1$ and $\theta_0$ is predicted to be   \begin{equation}  I = I_0 \cos^2[\theta_1 - \theta_0]  \end{equation}  where $I_0$ is the original light intensity.   An example for zero field is shown in Fig.~\ref{fig:PolarizationDataAtZeroField}
