 ``` 29 June 1998 Vol. 3, No. 26 THE MATH FORUM INTERNET NEWS Math & Time | Games - Learning Kingdom | Fractal Modeling - Shodor MATHEMATICS AND TIME INTERNET RESOURCES FOR HOROLOGY The Science of Time, Timekeepers (Clocks, Watches) and Timekeeping from The Teaching and Learning Center http://www.horology.com/horology/ A site with all kinds of resources for math explorations that involve time. Included are organizations; information sources; timepieces; subjects, issues, and topics in horology; and ways of finding and setting the exact time, including time zones and a time zone converter. You will also find links to a wide variety of WATCH AND CLOCK MUSEUMS: http://www.horology.com/horology/ho-edmus.html \|/ TIME SERVICE DEPARTMENT - U.S. Naval Observatory http://tycho.usNo. navy.mil/time.html An official Web source for the correct time in the United States. To find your local time zone, learn to convert from Universal Time, try directions for putting a clock on your own Web page, and more, see WHAT TIME IS IT? http://tycho.usNo. navy.mil/what.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GAMES FROM THE LEARNING KINGDOM http://www.learningkingdom.com/ For the very young, who want to play with the math they've just begun to learn. - BLANKETY-FIVE SQUARED http://www.LearningKingdom.com/five/ - ELEVEN TIMES http://www.learningkingdom.com/eleven/ Learn to square two-digit numbers that end in five, or quickly multiply two-digit numbers by eleven. See how each trick works by watching step-by-step examples, read why it works, and then test your skill and speed with a challenge. \|/ Also from The Learning Kingdom: Math in the Kingdom (MITK), a Web-based arithmetic tutor that teaches 1st, 2nd, and 3rd grade material directly over the Internet for a monthly subscription fee. Take the guided tour or experiment with a 10-day free trial to see if the program meets your child's needs (and whether it will crash your browser). http://www.LearningKingdom.com/math/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- FRACTAL MODELING TOOLS - Shodor Education Foundation http://www.shodor.org/master/fractal/curriculum/ Instructional resources and simulation software for generating different kinds of fractals. Lesson plans are available from within the simulations, and a Java version and a simulation running on a remote server are provided for each unit: The Fractal Microscope Mandelbrot and Julia sets, the algorithms used to create them, and the mathematics behind the graphics. The Snowflake Fractal Generator Specify a drawing rule that the computer will use to make curves like the Koch Snowflake. Sierpinski Gasket Model the 'Chaos Game'(a simple, apparently random process with a not-so-random result) and change the rules to make your own fractals. The NCSA-Shodor BRIDGE Project offers three other ways to explore integrating curriculum with interactive media: ChemViz - a quantum chemistry visualization tool SimSurface - a potential energy minimization tool using simulated annealing The Pit and the Pendulum - a quantitative investigation of Edgar Allan Poe's short story http://www.ncsa.uiuc.edu/Edu/Simulations/ For best viewing of this site, a fast connection and a Java-enabled browser are recommended. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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/students/ 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\ / \ / \ / | / \ / \ ```
