Hello,
in a notebook, I found and function to calculate the Feigenbaum 
bifurcation Diagram.
I principial understand the Feigenbaum, and I think I'm also able to 
write such an funcion by myself, but not in this compact way.
Can someone please explain me the meaning of the Symbols #, @ and &
Here is the Code:
Feigenbaum = Compile[{{
     ?, _Real}}, ({?, #} &) /@ Union[Drop[NestList[
       ? # (1 - #) &, 0.2, 300], 100]]];
thanks in advance
Stefan
