Some origami masters have looked at constructing geometric figures such as regular polyhedra from paper. In the other direction, some people have begun using computers to help fold more traditional origami designs. This idea works best for tree-like structures, which can be formed by laying out the tree onto a paper square so that the vertices are well separated from each other, allowing room to fold up the remaining paper away from the tree... Related theoretical questions include how many different ways a given pattern of creases can be folded, whether folding a flat polygon from a square always decreases the perimeter, and whether it is always possible to fold a square piece of paper so that it forms (a small copy of) a given flat polygon.

ORIGAMI. S YMMETRY. Reflection about a vertical axis. I NSPIRATION. Commissioned by high school mathematics teacher David Masunaga for a talk about origami, and published in Peter Engel's book Origami from Angelfish to Zen. S TORY. In April 1988 I attended the 25th anniversary reunion of the Design Science program at Harvard University's Carpenter Center for the Visual Arts . Although I hadn't actually attended the program, let alone Harvard, I felt such kinship with this merry band of artist-mathematicians that I showed up anyway. The program, founded by Harvard professor Arthur Loeb, is a uniquely interdisciplinary of 3d polyhedral geometry and sculpture. Equal parts art, mathematics and engineering, the program has produced one of the most interesting collection of alumnae I've ever seen. Talks at the event included: Peggy Weil talking about her vision of the Weatherium: a multi-story inverted polyhedral globe that you view from a platform floating on the inside, with a live projected image of earth's surface as seen from weather satellites. Amy Edmundson, who wrote a most illuminating book about Buckminster Fuller's geometry called A Fuller Explanation, giving a hands-on workshop on building structures out of toothpicks and marshmallows. You quickly learn that in order to build anything stable you have to use triangulated structures like tetrahedra.

Folding Geometry - Kayee Kwok (2000) Abstract Origami, originated from Japan, is an art of paper folding in which something as simple as a box or something as elaborate as a crane can be created without gluing, or cutting. The fusion of art and mathematics gives us Modular Origami. The idea is to build a geometric shape using many equivalent pieces of folded shapes. One of the shapes which I'll be talking about is the five intersecting tetrahedran. Transparencies

26. From The Origami-l Archives - David Lister On Why A Paper Square? wits against the paper and its inherent geometry. become the classical shape of paperfor folding. accepted shape for what we ordinarily call origami paper . http://www.worthhall.demon.co.uk/theory/lister/wysquare.htm

Why a paper square? Brunno Jammes asks (25th May), why we mostly use square paper for origami. He says there has been a discussion on our sister list, Origami-francais. Here is what I wrote, slightly edited for clarification. 1.A few months ago, I wrote in Origami-L about John Smith's ideas on "Origami Profiles" which analyses how each individual's preferences in folding fit into the general scheme of things. The theory accepts that everyone is entitled to adopt whatever rules for folding he or she chooses. A folder can use, or not use square or any other shape of paper at his or her absolute discretion. 2. Following from this a folder can choose to fold from a square or from a triangle or from A4 or a pentagon or a rectangle or a rhombus or a long ribbon of paper half and inch wide and ten yards long. He may even prefer silk ribbon or even string. Whether other people would include ribbon or string in their own concepts of Origami is another thing. 3. If you accept that cutting is legitimate (and cutting, too, fits into John Smith's Profiles of Origami), your can convert a square of paper into any shape you like. Or you can trim your dollar bill into a square. Or you can chop off any of those surplus bits of paper that get in the way. (No, I accept that most people who like to use scissors don't look at it in this extreme way, but I assert the possibility.) 4. Without even using scissors, you can convert most simple shapes of paper into most other shapes by folding alone. You can fold a square to make a triangle, or a hexagon or a 3 X 7 rectangle, even A4. So having done that, in theory, you can go on to fold anything that can be folded from a square equally from a Dollar Bill or anything that can be folded from a Dollar bill from a square. I write "in theory" advisedly, because all the preliminary folding to get the shape makes the model bulky and difficult or even impossible to fold in practice.

Cyberfolks Friendly Guided Web Site Tours Origami Sites for Beginners to Enthusiasts Host Rich Gray It is the old meeting the new, the cultured elegance of origami running smack up against the electronic ripple of the Internet. While it may seem odd to some that this delicate art of paper-folding would thrive in the world's largest paperless medium, that's exactly what it's doing. There are numerous sites on the World Wide Web dedicated to origami. They range from simple "look-what-I-did" photo collections to intricate galleries built upon reams of information. So if you're ready to move beyond the crumpled paper-ball stage (makes a mean projectile though, doesn't it?), follow me as we head into the fold. Paper fold, that is. Joseph Wu's Origami Page For sheer beauty and complexity of design, you just can't beat this site. The photo gallery with its Creatures of Myth should give you a pretty clear idea of what can be achieved with origami and a lot of experience. Joseph also provides links to numerous other origami sites, as well as pointing to folding diagrams in several different formats (GIF, PDF, Postscript). A real source of inspiration! The Garden of Origami The Garden of Origami is another great site to start with. A strong Oriental feel runs through this site, from the simple-yet-elegant design to the recurrent theme of origami as philosophy. There are extensive links to folding patterns on the Internet, as well as a great section on using origami in the classroom to teach such things as geometry and Oriental culture. This is a great resource for teachers.

Math topics are not often considered fodder for unit studies. Most people have a figure or number oriented view of mathematics. They think in terms of number sentences, problems and formulas. From that point of view it can be difficult to see all the possibilities for language, history and science study that can be found in a mathematical topic. Naturally visual, geometry works well as a first mathematical unit study. Geometry is often offered piecemeal throughout most curriculums. In the early grades it is usually given a chapter in math texts. Saxon math books sprinkle it all the way through their upper elementary, junior high and high school level books. Eventually in high school, geometry is given an entire year in most curriculums. Key Curriculum Press is unique in offering a geometry curriculum for the upper elementary years called

39. Ch.5 Connecting geometry©. Chapter 5. Have you ever heard of origami, the Japanese artof paperfolding? There are some fascinating web sites on this topic. http://www.k12.hi.us/~csanders/ch_05TriangleProp.html

Connecting Geometry Chapter 5 Triangle Properties It may seem surprising to you, but being able to prove two triangles are congruent will now allow us to discover and prove many geometric properties, not only about triangles but about other figures as well! In this chapter, through your explorations on The Geometer's Sketchpad, you will discover many properties of isosceles triangles, equilateral triangles, right triangles, and of triangles in general. Let us begin the discoveries by looking at the symmetries of triangles, and see where this leads us. Let's begin with the most symmetrical triangle of all: the equilateral triangle. If you construct an equilateral triangle on Sketchpad, and print it out, you can do some interesting symmetry experiments by simply folding the triangle. Begin by folding any vertex over onto the other vertex, as in the sequential steps below: If you did this by actually folding an accurately constructed equilateral triangle made of paper, you probably noticed that the triangle is perfectly symmetrical, with reflection symmetry. Unfold the triangle and then fold it again, folding any vertex onto any other vertex. What seems to be true about the equilateral triangle? This symmetry will tell us a number of properties of the equilateral triangle, properties of its sides, its angles, the medians, altitudes and angle bisectors. We will explore these properties using the Geometer's Sketchpad as well as by folding. What would happen if you tried this with an isosceles triangle (one that was definitely not equilateral)? Construct an isosceles triangle on GSP and print it. Then try the folds shown below:

Roland Piquepaille's Technology Trends How new technologies are modifying our way of life samedi 18 janvier 2003 Computational origami at the MIT It's the weekend, so today we'll talk about a pastime: origami. Erik Demaine must be a happy guy. At 21, he became the youngest professor at the Massachusetts Institute of Technology (MIT). And he's being paid to have fun. He works on computational origami the geometry of paper folding which interests not only hobbyists or MIT professors, but also the manufacturing industries. Steve Nadis interviewed him for the New Scientist, looking back at his itinerary. Here are some selected questions and answers. Q: What was your first real accomplishment in mathematics? A: Six years ago, when I began my PhD work in computational geometry at the University of Waterloo in Ontario, my dad remembered "the paper cut problem" from an article written in the 1960s on paper folding and mathematics. The idea is to take a piece of paper, fold it any way and as many times as you want, and then make one straight cut and see what shapes you get. The question is, are all shapes possible? I worked on this problem for two years at Dalhousie with my dad and adviser Anna Lubiw. After experimenting for a while, we realised you could make all kinds of shapes, such as butterflies, swans, hearts or stars
