Math Links (serious and otherwise)


Math arXiv Math arXiv Pre-Print (e-print) server. Get the latest math articles without waiting for journal publication.
The American Math Society's MathSciNet is a searchable Web database providing access to basically every math article in print from 1940 to the present. (Requires subscription)
Wolfram Math World claims to be "the worlds most extensive math resource." This free resource is something better than an extensive math dictionary, sometimes as good as a reference text, and it is "built with Mathematica Technology." I usually forget how powerful it is until it turns up on a Google search, so I am finally adding it as a link here to help me remember.
Knot Info is maintained by the "Knot Guys" at Indiana University, and basically is a database of everything known about knots.
KnotPlot is software for drawing and computing knotty things.
SeifertView is an awesome program to help visualize and explore Seifert surfaces.
A pretty detailed Topology Glossary
The Clay Math Institute has designated seven Million Dollar Problems. Try and solve one of these!
A list of Famous Problems in the History of Mathematics, from the Math Forum Project.
The Fields Medal is the math-equivalent of a Nobel Prize.
The Mathematics Genealogy Project lets you trace your math family tree by advisor.
Similar to Math Geneology, The Erdös Number Project measures how far removed you are from Paul Erdös, by publication.
A work in progress, but here is a little something to get you started learning TeX, a markup language for typesetting math documents
At Jeff Weeks' Topology and Geometry Software page, you can download the SNAPPEA program, a great tool for studying hyperbolic 3-manifolds and knot complements. He also has torus and Klein Bottle games like tic-tac-toe, chess, mazes, crossword puzzles, word searches, and jigsaw puzzles.
Ever wonder about colors on the surface of a bubble, or the shapes formed when bubbles meet? Here's a page that'll explain everything you ever wanted to know about bubbles, from chemical composition to minimal surfaces, thin film interference to bubble recipes.
The Mandelbrot and Julia Set Explorer is one of the best sites I have found for studying these sets. There you'll find an on-screen java applet that is interactive and user-friendly. Clicking a point in the Mandelbrot set zooms in on a region, and displays the associated Julia Set for that point. (For a powerful downloadable program, look elsewhere for the free FracTrip.)
