If you've been wondering about Zeisel Numbers, Machin's Merit, How (or How NOT) to Prove Pi is Irrational, Golf Tournaments and Latin Squares, or The Importance of Being Urnest, this is the site for you. It contains over 300 articles on a variety of mathematical topics, including:
- Algebra - Calculus and Differential Equations - Combinatorics - Geometry - History of Mathematics - Music - Number Theory - Physics - Probability and Statistics - Set Theory and Foundations
and a 'Most Wanted List' of elementary unsolved problems, link-referenced and updated by Brown as others solve them - 'elementary' because no special background is required to understand them, 'unsolved' because Brown doesn't know the answers and they've been posted on the newsgroup sci.math but no one has answered them.
Mathematics can be difficult to convey in HTML. Johnston, a former math teacher and current editor of textbooks for Houghton Mifflin, writes in detail about the problems, gives suggestions for using ASCII and GIF files, and supplies notes on proposals andexperimental projects such as MINSE, the Integrator, Java applets, and Portable Document Format (PDF).
Typesetting Math is an essay from a larger collection wherein Johnston offers advice about speed, accessibility, validity, and navigability on the Web, with links to information about these issues:
