                THE GEOMETRY JUNKYARD
     David Eppstein, Theory Group, ICS, UC Irvine

      http://www.ics.uci.edu/~eppstein/junkyard/

A collection of Usenet clippings, Web pointers, lecture 
notes, research excerpts, papers, abstracts, programs, 
problems, and other material related to discrete and 
computational geometry - some serious and much also 
entertaining.

Eppstein sorts his "junk" into "piles" (topics) such as:

 - Circles and Spheres 
 - Covering and Packing 
 - Geometric Topology 
 - Knot Theory 
 - Lattice Theory and Geometry of Numbers 
 - Origami 
 - Polyhedra and Polytopes 
 - Randomness and Geometric Probability 
 - Symmetry and Group Theory 
 - Width, Diameter, and Geometric Inequalities 
 - Three-dimensional Geometry 
 - Many-dimensional Geometry 
 - Open Problems 
 - Lesson Plans and Teaching Materials 
 - Software and Animations 

... and many more.

Don't miss Eppstein's other pages, GEOMETRY IN ACTION, which
is devoted more to applications and less to pure math, and 
his non-geometrical RECREATIONAL MATH area:

                   WOMEN AND MATHEMATICS

    http://mathforum.org/social/math.women.html

This collection of resources from the Math Forum for 
information about women and mathematics offers links to 
sites of general and historical interest, publications, 
programs, and major organizations. 

Featured sites include:

 - Women in Math Project, by Professor Marie Vitulli of
    the University of Oregon
 - Women Mathematicians, biographies written by students
    at Agnes Scott College
 - The Ada Project (TAP), Resources for Women in Computing,
    a resource clearinghouse
 - Girls' Attitudes, Self-Expectations, and Performance in
    Math, an annotated bibliography
 - NSF Report on Issues of Equity, the 1994 National Science
    Foundation report, online
 - Summer and Mentoring Programs for Undergraduate Women
 - GirlTECH, a Teacher Training and Student Council Program

The materials on this page are among those catalogued in
the Forum Internet Resource Collection.  To find even more
information about women in math and science, try searching

                   BRAHMAGUPTA'S FORMULA
                A Webmaster Correspondence

http://mathforum.org/help/webmaster/bramputa.html

A conversation demonstrating how educators can draw on the 
Web as a learning resource and contribute to it in response
to real educational needs. This conversation shows learning
as a continuing process and presents the sort of questioning
and collaboration that make for productive inquiry.

Reflections from the three persons involved are interspersed
with their original eleven email messages. The thoughts of
Richard (a Math Forum webmaster), Grace (who posed a question
about Bramputa's theory), and Jim Wilson (Math Education, 
University of Georgia) offer ideas about how the World Wide 
Web, the Math Forum, webmasters, and users can facilitate 
education and community.

 "Jim, Grace, and I have never met - yet a new Internet 
  resource emerged from a conversation that began with 
  Grace's e-mail to the Math Forum webmasters, and 
  ultimately invited Jim to contribute his work as a 
  mathematics educator and Web page developer." - Richard

Jim has added a new Web page addressing the difficulties in
proving Brahmagupta's formula to his other work, which was
featured in the Jan. 20 issue of this newsletter.
