\column{0.45\textwidth}
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\column{0.55\textwidth}
Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.
\end{columns}
It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
