Welcome! This is a collection of short articles designed to provide an introduction to the areas of modern mathematics and pointers to further information, as well as answers to some common (or not!) questions. The material is arranged in a hierarchy of disciplines, each with its own index page ("blue pages"). To reach the best page for your interests, use whichever of these navigation tools ("purple pages") you prefer:

[Browse]		Choose from a list of subject headings.
[Search]		Search for a topic by keywords.
[Visual]		Click on territory in the "MathMap" above (or in an annotated version).
[Verbal]		Take a tour of the mathematical landscape. (Good for newcomers.)

There is a backlog of articles awaiting editing before they are referenced in the blue pages, but you are welcome to snoop around
