But for many people, going beyond the static images and formulas of current mathematics texts requires an effort in creative visualization which is often beyond their means. The Living Mathematics Project hosted at SunSITE UBC is working to apply recent advances in computer programming languages and the technology of the World Wide Web to construct a new medium for the communication of Mathematics.

Votes:0 A Focus+Context Technique Based on Hyperbolic Geometry for Visualizing Large Hierarchies. John Lamping, Ramana Rao, and Peter Pirolli Xerox Palo Alto Research Center 3333 Coyote Hill Road Palo Alto, CA lamping@parc.xerox.com rao@parc.xerox.com pirolli@parc.xerox.com © ACM Abstract We present a new focus+context (fisheye) technique for visualizing and manipulating large hierarchies. Our technique assigns more display space to a portion of the hierarchy while still embedding it in the context of the entire hierarchy. The essence of this scheme is to lay out the hierarchy in a uniform way on a hyperbolic plane and map this plane onto a circular display region. This supports a smooth blending between focus and context, as well as continuous redirection of the focus. We have developed effective Read More Go to Site A Gallery of Interactive On-Line Geometry Votes:0 Register: Tell Us What You Think Up: The Geometry Center Home Page Gallery of Interactive Geometry: In order to enjoy this exhibit, you will need a Web browser that understands graphical Fill-Out Forms.

It could be called the perimeter of the circle. How to find the circumference of a circle: The circumference of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56 If you know the radius, the diameter is twice as large.

The ancient Egyptians used string. They knotted it and stretched it to do their measuring. A very young child can get the idea of making geometric measurements the same way. Children can begin to comprehend the rudiments of geometry with string by being measured themselves. In kindergarten and first and second grade, a teacher can take children's measurements and use their respective heights as basic length-units for having them measure things in the immediate environs. That's what the Egyptians did. They called the surveyors "rope-stretchers." A string with knots carefully made at both ends becomes your basic line s Read More Go to Site Globalizing two-dimensional unstable manifolds of maps Votes:0 Up: Available formats Globalizing two-dimensional unstable manifolds of maps Bernd Krauskopf Theoretical Physics Free University De Boelelaan 1081 1081 HV Amsterdam The Netherlands berndk@nat.vu.nl Hinke Osinga The Geometry Center University of Minnesota 1300 South Second Street Minneapolis, MN 55454 U.S.A hinke@geom.umn.edu Abstract We present an algorithm for computing the global two-dimensional unstable manifold of a normally hyperbolic invariant circle of a three-dimensional map. Our algorithm computes intersections of the unstable manifold with a finite number of leaves of a chosen linear foliation. This allows us to guarantee the quality of the mesh on this manifold. We compute growing pieces of the unstable manifold by using a method that does not depend on the dynamics on the manif Read More Go to Site Hamilton - Math to Build On: Web Site Contents Votes:0 Math to Build On: Web Site Contents Table of Contents || Introduction || Glossary Excerpts from the book Math to Build On, by Johnny and Margaret Hamilton.

The Hexaflexagon described here has six different faces, thus the name Hexahexaflexagon . An interesting chapter that describes Hexaflexagons can be found in Martin Gardner's book Mathematical Puzzles and Diversions , first published in 1959 by Simon and Schuster, and reprinted in both hard-cover and paperback by several publishers including Penguin Books (U.S., U.K. and Australia) and the Chicago Press. The book consists mainly of Gardner's articles published in the Recreational Mathematics column of Scientific American .

My college education was in mathematics and I have had a lifelong interest in both mathematics and the teaching of it. On this page I present several topics in high school level mathematics. We are constantly being told about how poorly Americans are doing in science and mathematics. I don't know how much truth there is in all this. I do know that we are living in an age of information and that our schools have not yet adjusted. The ability to reason abstractly is going to be of increasing importance. When I went to college I did some substitute teaching between the end of the college year and the beginning of the public school summer vacation.

Details of the construction of this object are given, along with movies of a spinning hypercube. An "inflated" hypercube By inserting new vertices into the edges and faces of a hypercube, it may be "inflated'' to give an approximation to the hypersphere. Hypertorus Adding together three vectors, each rotating in 4-space with different frequencies and amplitudes, produces a trajectory along the surface of a hyper-torus. How the models were produced Details of the mathematics needed to model the structures, and how to turn the numbers into an animation. Useful references A selection of recommended books.

Projections have already been extensively used for this purpose. For instance, those who know what a hypercube is have probably seen the projective views that are so common, such as the two shown here. Fewer people know, however, that the hypercube also exists as a series of 3-dimensional cross-sections: Visualizing higher dimensional objects is, like many scientific visualization tasks, a problem of reducing the dimension of the data. Projections do this by "squashing" the object into a lower dimensional space. But besides a change of coordinate information, the object is essentially unchanged- Read More Go to Site POV-Ray - The Persistence of Vision Raytracer Votes:0 Download Hall Of Fame Docs FAQ Resources Community Support Search Welcome The Persistence of Vision Raytracer is a high-quality, totally free tool for creating stunning three-dimensional graphics .

It is known that the line to be found is a catenary. Depending on the concrete boundary conditions, there can exist either two solutions of the Euler equation or alone or none. These solutions are catenaries. In traditional courses, one does not pay attention enough to the case of absence of the classic solution. In the numerical solution by the Euler method, the broken-wise solution is easily discovered. These are two disks for which the generating line consists of two vertical segments and a horizontal one lying on the axis of rotation. Moreover, the broken-wise solution can be a global minimum in the zone of existing the solution for the Euler equation ( Ahiezer, Read More Go to Site Question Corner Votes:0 Navigation Panel: (These buttons explained below ) Question Corner and Discussion Area This page has been a place for high-school students and others to ask questions about mathematical topics and receive accurate and informative answers.

After working together to accomplish a three panel stained glass mural that now adorns the math and science wing, each student designed a fish in a hexagon or pentagon that came together in the C60 buckyball spherical geometric form. This idea emerged when we were in the middle of the mural and visited Virtual Reality Polyhedra web site. There we found a conceptual stained glass sphere.

Images rendered by POV-Ray 3.1. Background Equations and Graphics Animation Links Definition Let p 0 , p 1 , p 2 , p 3 be quadratic polynomials in two variables u, v. This means they're of the form p i (u,v)=Au 2 +Buv+Cv 2 +Du+Ev+F for constant coefficients A, B, C, D, E, F. If you plot the parametric graph (x,y,z)=(p 1 /p 0 , p 2 /p 0 , p 3 /p 0 ) for some range of input values u, v, the image should be a two-dimensional surface in (x,y,z)-space. It's called a Steiner surface patch, but what does it look like? This web site lists all the different geometric types of Steiner surfaces.

Long before the Greeks worked out the abstract ideas and discipline of Euclid's geometry, the Egyptians, who had little interest in theorizing, used straight edge and a rope compass to build the pyramids. They applied their tools to design and build their fabulous temples and tombs long before Thales worked out his theorem of similar shapes and proportionate sides of triangles.
