Ed Pegg, Jr. has posted a remembrance of how the late Martin Gardner influenced his mathematical thinking. Drawing on WolframAlpha, Demonstrations, and MathWorld, Pegg's resources include:
 Knots
 Random walk
 Möbius strip
 Klein bottle
 Graph theory
 Necklaces
 Dragon curve
 Fibonacci numbers
 Latin square
 Pascal's triangle
 Zeno's paradox
NWMI Math Short Courses
http://www.math.washington.edu/~nwmi/sum/summer2010/prog/mini.html
Northwest Mathematics Interaction, an affiliate of Park City
Mathematics Institute, offers a special professional
development opportunity this summer at the University of
Washington in Seattle, July 2830.
The program coincides this
year with a conference celebrating the geometry and other mathematics of Vic Klee
and Branko Grünbaum. Brian
Hopkins will facilitate a group of teachers who will attend
selected research talks, with preparation and reflection
sessions.
Register before June 15 to save $25.
There is also space in the Numerical Delights short course,
July 2627. This course is intended for high school teachers or
anyone else interested in the historical development of number
theory, exploring topics relevant to the high school algebra
and precalculus classroom. The link above includes information
about both courses.
Geometry Playground
http://www.exploratorium.edu/geometryplayground/
San Francisco's Exploratorium is opening its newest exhibit on
June 25: the Geometry Playground. Peoplesized exhibits let you
use your hands, brain, and body to play with physical
demonstrations of geometry concepts. Exhibits fall under the
categories of seeing, moving, and fitting things together, and
include interactive artwork by geometric artistsinresidence.
The Geometry Playground closes at the Exploratorium on September 6,
then travels to St. Paul, San Diego, and other science museums
in cities around the country.
