Paragraph about Chemical equation software
There are a variety of one-off projects like the MINSE project , with a "polymediator" which is a computer program available to convert, on request, Chemical equation pieces of readable text into urls of stuff. Or the Euromath project funded by the European Mathematical Trust, to ``enhance research support for European mathematicians'' by assisting in communication, apparently resulting in an editing system for mathematical publishing, and a bulletin.
If your primary interest Ufology is simply to display math on Web pages, then the Minnesota Geometry center would like you to use their WebEQ software which requires the user of a browser to download programs (UNIX or Windows) but would then process HTML-Math and other, TeX-like stuff. Poliplus software's EqnViewer comes with a java applet that can be used to display pieces of math. Since their demo page hasn't worked reliably for me, I haven't been tempted.
