I am using `minipage` environment in one slide of my `beamer` presentation. Basically, what I would like to have is the following: 

top of the slide: a picture on the left and some description on the right. The text on the right should be in smaller fonts that usual.

Bottom of the slide: add additional information (using regular font size). 

I wrote the following:

```
\newcommand\Fat{\fontsize{7}{7.2}\selectfont}
\section{Extras}
\subsection{Personal Profiles} 
\begin{frame}{The minipage environment}
\frametitle{Extras}
\framesubtitle{Personal Profiles}
\begin{minipage}{0.25\textwidth}
\includegraphics[width=2.5cm,height=3cm]{images/PN}
\end{minipage}
\begin{minipage}{0.5\textwidth}
\Fat
Adam Smith (B.Sc. London, M.Sc. and Ph.D. New York, M.Sc. by Research Los Angeles) Full
Professor of Physics (Hong Kong) and Visiting Professor of Physics (Milan). He was a Fulbright Research Fellow at Carnegie
Mellon University.
\end{minipage}\bigskip\\
Adam Smith is currently working on three project
\end{frame}

```

Everything works fine. The only point is that I would like to have the text on the right hand side in the `minipage` environment better distributed (i.e. I would like to have it in less and longer rows). How I can do that?
