Tips from the Math Forum
By Gene Klotz
Sponsored by Philadelphia's Drexel University, the Math Forum @ Drexel was launched early in the
history of the World Wide Web as a place where math teachers could talk about teaching. Students and
nonschool folks with their own interests and curiosities soon discovered the site and joined the
conversation. Today, the Math Forum offers much more than discussion.
The following are a dozen math resources—six from the Forum itself, and six from the larger pool of
the Internet—that our members would recommend to science centers looking to help their visitors see
and understand the math all around them.
On the MathForum
 Symmetry and Pattern, the Art of Oriental Carpets was created with Carol
Bier of the Textile Museum. A nice answer to "Where's the math?" in one particular world.
 Ask Dr. Math is indexed by grade level and topic, but don't be put off. The
volunteers who answer questions here bring experience and perspectives from engineering, business,
government, law, biology, computer science, psychology, and many other areas of life. Post to Ask Dr.
Math, making it clear that your question is museumrelated, and you'll get serious attention.
 The Internet Mathematics Library welcomes formal and informal learners (our
search engine knows dozens of ways to spell "Pythagoras"). Check Applications/Connections at the end of
Mathematics Topics, or look at the Museums section under Resources, subcategory Organizations (let us know
how we can improve this area).
 The Internet Newsletter is in its 10th year of weekly reporting on Internet
math resources. Many topics here have a science component—take a browse!
 Math Tools is a digital library containing over 3,000 software tools for
teaching and learning mathematics. If you don't see what you want, ask; perhaps a developer can answer your
wish.
 Problems of the Week (PoWs) are creative, nonroutine challenges for students
that might be helpful for afterschool programs. Technology Problems of the Week (tPoWs) are now
offered in Spanish.
Beyond the MathForum
There are hundreds of mathematics resources on the Web. The following are a few recently featured in our
Internet Newsletter. The first two are high quality and high level; the rest are more accessible.
 Mathworld
is "a comprehensive and interactive mathematics encyclopedia intended for students, educators, math
enthusiasts, and researchers." A nice resource if you know what you're looking for; otherwise fun to
browse. Check out Headline News, for example, for an explanation of the math behind tsunamis.
 The Mathematical Atlas, a
Gateway to Modern Mathematics, is a collection of short articles that introduce the subject
areas of modern mathematics, describe a few of the milestone results and topics, and point to further
information.
 MathSite
is an interactive source for seeing, hearing, and doing mathematics.
 iLumina
is a digital library of shareable undergraduate teaching materials; math downloads include applications for
modeling realworld phenomena like world population growth, predators/prey, and marine pollution.
 Faces of
Mathematics focuses on 20 influential mathematicians alive today (including four women),
revealing the human side of mathematical endeavor.
 Phyllotaxis
is an interactive site for the mathematical study of plant pattern formation.
Gene Klotz is the Buffington Professor of Mathematics, Swarthmore College,
Swarthmore, Pennsylvania, and founder of the Math Forum @ Drexel. Science centers interested in partnering
with the Math Forum are invited to write to him at gene@mathforum.org.
