1 May 2000 Vol. 5, No. 18 THE MATH FORUM INTERNET NEWS Knot Theory Online - Payne Ifors TutORial Project - Sniedovich | Exploring Data - Boggs KT (KNOT THEORY) ONLINE - Payne http://www.freelearning.com/knots/ A site designed to introduce mathematics students at the high school and college levels to an area of mathematics seldom explored in the typical math classroom: the theory of knots. Site contents include: - A Brief History of Knot Theory - Introduction to Knots What is a mathematical knot? The central problem of knot theory How do we work with knots? Classifying knots Properties of knots Knots vs. links - Advanced Knot Theory Topics Prime and Composite Knots The Connected Sum Stick Knots Wild Knots Coloring Knots and Links References - Activities to Get Your Hands on Knot Theory Classroom-ready lessons - Knot Funny - "Knotty" Fun for All Activities, jokes, and links to other knot sites. With a small picture gallery of knot photographs and some animations: http://www.freelearning.com/knots/wanted.htm -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- IFORS TUTORIAL PROJECT - Sniedovich Operations Research/Management Science (OR/MS) http://www.ifors.org/tutorial/ A library of self-contained modules, each dedicated to a relatively small OR/MS topic, from the International Federation of Operational Research Societies (IFORS). Modules typically contain some of the following: text, images, computer code, animation, and user interface features for interactivity. Sample tutORials include modules on: - Dynamic programming - Linear programming Die Hard at the Pub The Simplex Place Towers of Hanoi Virtual Duality Shortest Path Problem Dijkstra's Algorithm - Simulation Knapsack Problem M/M/1 Queues Critical Path Method G/G/s Queues Chained Matrices Queueing Networks Random Generator - Integer programming Tester Royal Optimization 8 Easy Pieces - Other Geee Park - Linear Algebra Row Operations The Equator The Inverter -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- EXPLORING DATA - Rex Boggs http://exploringdata.cqu.edu.au/ After a brief absence, this site, produced in conjunction with the University of Queensland, has returned to the Web. Investigate activities, worksheets, overhead transparency masters, datasets, and assessment to support the exploration of data. An extensive collection of articles and a page of resources for introductory statistics are provided, including texts, websites, datasets, Java applets, and mailing lists. Topics include: - patterns, stemplots, dotplots, histograms - measures of spread - boxplots, normal plots, scatterplots - assessment - linear regression - normal distribution - probability - sampling, confidence intervals - hypothesis testing, curve fitting Datasets are available in tab-delimited and spreadsheet formats. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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\ / \ / \ / | / \ / \
