Well, here's what happens when I delete the \usepackage{preview}  
line: I get an error, and immediately after the preview is done, the  
pdf that usually shows the whole document changes so that I just get  
the previewed equation, in this case, the law of gravity, neatly  
typeset all by itself with no surrounding page or "Hello" in my PDF  
viewer (skim.app in this case).

So, what I am using is:

\documentclass{article}
\begin{document}
Hello.

$F=G\frac{mm'}{r^{2}}$
\end{document}

this time the error I get is:

ERROR: Preview: Snippet 1 started.

      F=G\frac{mm'}{r^{2}}$
--- HELP ---
The auctex option to preview should not be applied manually.  If you
see this error message, either you did something too clever, or the
preview Emacs Lisp package something too stupid.
