Binary Variable help

I've asked Time Magazine for this before, but I lost the email with his response.

I have a binary variable and I want to create an equation where I have

\theta = { 0 and 1

Where the 0 is on top of the 1 and the lbrace is large.

Time Magazine

\begin{align*}
% Put your LHS text before the "&" on the next line
\theta & \left\{
\begin{array}{cc}
% Put top line of RHS betwen "&=" and "\\" on the next line
&= 0 \\
% Put bottom line of RHS after "&=" on the next line
&= 1
\end{array} \right.
\end{align*}

You sir, are a King among men.

Much more Kinglier then say Economiste Monetaire! (who didn't reply first!)

If you're using amsmath (which you'd need for align* anyway), you can use the "cases" environment for the RHS with the single large brace on the left.

\documentclass[a4paper,oneside,12pt]{article}

\usepackage{amsmath}

\begin{document}

\begin{equation*}
  \theta =
  \begin{cases}
    0 \\
    1
  \end{cases}
\end{equation*}

\end{document}
