I would like to start writing a new shape library, similar to the one for laying out circuits (circuitikz), for laying out optical setups (laser table, mirrors, lenses, detectors etc.) I'm not having a lot of luck finding documentation of that part of the TikZ/pgf command set. I just started ...

To follow up what localghost said, I just finished writing a JCP paper with revtex. Start your document with:

\documentclass{revtex4-1}

I've got a dual screen setup and have been running TXC 2.0 Alpha 1 (build 1012). I have my TXC window open one one screen and my PDF viewer on the second. In order to maximize my writing space, I've undocked the build/error panel and have it on the same screen as the PDF, since I only need to look ...

I was playing around with the new TXC this afternoon and I realized that I have never used the Find 1 or Find 2 panels, either in the previous version or this one. In fact, I can't remember ever seeing anything in those panels, just a blank. I tried doing a search while the Find 1 panel was open ...

I installed MikTeX 2.7 on my new computer (XP SP3) a couple weeks ago, and transferred my LaTeX documents over from my old laptop. I tried to build my thesis, which uses about 20 packages. Whenever MikTeX tries to install one of the packages, I get a "Not a valid remote package repository" error. I ...

I guess it's a fair trade, and with a few minutes of tweaking, my table looks much better now.

Thanks for your help!

Almost perfect! However, the code above fixes the column widths, whereas before the widths were calculated on the fly. Is there a way for the widths to be variable, or do I just need to mess with it until they're right?

I've got a table with pictures in them, a generic version of which is below. When I compile this, whether I use longtable or tabular, the text entries are aligned at the bottoms of their respective cells, with the baseline of the figures. I would like for them to be centered vertically. On the last ...
