Its goal is to raise awareness of the beauty, elegance, and usefulness of elementary geometry in research and in teaching. The journal focuses on concrete but challenging problems; papers, in English only and downloadable in postscript and PDF formats, discuss the interesting history of the subject. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE SHAPE OF THE UNIVERSE: TEN POSSIBILITIES Colin Adams and Joey Shapiro http://www.amsci.org/amsci/articles/01articles/Adams.html An abstract of an article featured in the September-October, 2001 issue of the American Scientist discussing recent experimental evidence suggesting that the shape of the universe may be found among the ten orientable Euclidean 3-manifolds. Download the file, foldupcube_print.pdf, and construct a model of a 3-Torus: http://www.amsci.org/amsci/articles/01articles/foldupcube_print.pdf \|/ EXPLORING THE SHAPE OF SPACE - Jeff Weeks http://www.northnet.org/weeks/ESoS/index.html "Exploring the Shape of Space" introduces students to 1-, 2- and 3-dimensional geometry by exploring some possible shapes for our 3-dimensional universe. The students learn by example, using paper-and-scissors activities, pencil-and-paper games, computer games, and the computer-animated video "The Shape of Space" to explore a few of the simplest possible universes. Throughout the unit, geometry interweaves with cosmology, including current research efforts to determine the shape of the real universe. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GEORGE WASHINGTON: SURVEYOR AND MAPMAKER Library of Congress http://lcweb2.loc.gov:8081/ammem/gmdhtml/gwmaps.html An essay on George Washington's lifelong association with geography and cartography, "Tracing the Maps in George Washington's Life" contains: Washington as Public Land Surveyor - Boyhood and Beginnings - The Fairfax Connection - Culpeper, the Frontier, and Alexandria - The French and Indian War Washington as Land Speculator - Building a Gentleman's Estate - Western Lands and the Bounty of War - Cartography and Leadership in Revolutionary Times The work includes links to images of the former president's diaries, surveys, and his handwritten exercise books (c.1745), which feature lessons in geometry (School Copy Book: Volumes 1 and 2) and several practice land surveys Washington prepared at the age of sixteen, a decade before the Revolutionary War. http://lcweb2.loc.gov:8081/ammem/gwhtml/gwseries1.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Mathematics Library http://mathforum.org/library/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ 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\ / \ / \ / | / \ / \
