\subsection{\bf Numbers---Genuinely Random}

\begin{slide}
\begin{itemize}
\item One needs specialized hardware to generate true random numbers,

\item e.g.,
%\vspace*{10pt}

%\vspace*{10pt}
for successive decays ($\Lambda\rightarrow p \pi^-$) of a bunch of
$\Lambda$'s.  

\item There are a lot of difficulties here. 

\begin{description}
\item{$\bullet$} Not only must you measure $\theta$ in an unbiased fashion 
(impossible), 
\item{$\bullet$} but also to find a random number with 32 bits of precision 
would require several separate $\theta$ values.
\item{$\bullet$} Maybe each gives four bits of information and so eight
measurements of $\theta$ are needed to get one random number.
