This web page codes math using MathML. At the time of writing, few browsers interpret MathML, so I use a java applet (WebEQ) to interpret and display the MathML. (WebEQ can also interpret TeX-style markup, which simplifies the task of publishing scientific papers on the Web.)

For faster viewing, you can download an archive file containing the WebEQ Java Applet, and store this archive on your local machine. The archive is availble as a JAR archive for users of Netscape Navigator, or as a CAB archive for users of Internet Explorer. (You can read more detailed instructions about doing this here.)
