9 June 1997 Vol. 2, No. 23 THE MATH FORUM INTERNET NEWS Geometry Junkyard | Women and Math | Brahmagupta's Formula 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: http://www.ics.uci.edu/~eppstein/geom.html http://www.ics.uci.edu/~eppstein/recmath.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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 our database: http://mathforum.org/dumpgrepform.html Enter the keywords "women science" (just the words, not the quotes). -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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. http://jwilson.coe.uga.edu/emt725/brahmagupta/brahmagupta.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problem of the Week http://mathforum.org/geopow/ Internet Resources http://mathforum.org/~steve/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ |
