Hi,
I just tried my presentation on a projector, and the math is not very
visible. Specifically - is not visible at all. I was using
\usepackage{concmath}to get a set of thick fonts. Is there another font
which is thicker or someway I can boldify all the math.

I have two equations which are essentially the same except for an
\overbrace. Separately their code would be like
\begin{equation*}
A = xyzp
\end{equation*}
\begin{equation*}
A = x\overbrace{yz}^{B}p
\end{equation*}
I would like to display the first on overlay 1 and the second on overlay
2. However, I want to adjust the spacing in the first overlay so that
when the second overlay appears all that appears is the extra brace and
B. In particular we need to leave some vertical space before the
equation and horizontal space between x and y and some between z and p.
Is it possible to achieve this?
My attempt at something like
\begin{equation*}
A = x\onslide{2-}{\overbrace\bgroup}yz\onslide{2-}{\egroup^{B}}p
\end{equation*}
did not work.

boldmath? See a latex manual.

This should have been an \onslide* question according to the subject.
And yes, you can use that to do the thing.
\begin{equation*}
\onslide*{1}{A=xyzp}
\onslide*{2}{A = x\overbrace{yz}^{B}p}
\end{equation*}
It's as simple as that. Don't try to make more efficient things with
\bgroup etc. That'll just cost you and us time.

I have not had this issue and I haven't heard of anyone else having it either...not with invisible equations or with hard to read equations. Do the pdfs look fine? Perhaps you might find a nice set of fonts to your liking in this pdf: http://www.tug.org/pracjourn/2006-1/hartke/hartke.pdf But again, it seems strange to me that you can't see the equations.

Suppose you have the following code
----------
\begin{equation*}
\onslide*{1}{A=xyzp}
\onslide*{2}{A = x\overbrace{yz}^{B}p}
\end{equation*}
STUFF
-----------
In the first overlay, you have "A=xyzp" followed by STUFF. So far so good.
In the second overlay, STUFF gets moved lower because the overbrace
equation requires more vertical space than the one without.
Hence the audience will see STUFF moving down abruptly.

The mathmode document by Herbert Voss (see ctan) also provides nice examples of this. -Hendri.

This topic was touched some time ago, focusing the heveticalfont (see
the archives). You may also try to use some math postscript
font(mathpple.sty, mathptm.sty,
mathptmx.sty).
