Teachers are requested to make their own contributions to this page. These can be in the form of comments or lesson plans that they have used based on this material. Please send email to the author at to inquire. Pages can be kept at Rice or on your own server, with a link to this page. Putting mathematics onto a web page still presents a significant challenge. Much of the effort in making the following pages as nice as they are is due to Dennis Donovan Boyd Hemphill added two nice appendices. Susan Boone helped construct the Table of Contents.

    References Endorsements References N ATIVE AMERICAN GEOMETRY is a physical, proportional geometry that originates from the simple circle. A growing body of architectural and iconographic evidence from Native America suggests it was a relatively common tradition that has been practiced for at least two thousand years. This is the same type of geometry that was discovered and developed by the ancestors of many peoples in many places, from China to the Mediterranean Basin to the British Isles. Currently, it resides among the logo designers of Madison Avenue. Generally, it maintains a similar methodological structure to the Middle Eastern tradition of classical geometry that is limited to operations carried out by the compass and straightedge, or two sticks and a rope. In the anthropological world, there are generally two ways traditions come into being in any particular culture: diffusion or borrowing from another culture; and, independent invention or discovery. Did the geometry have a single source and diffuse around the world over a period of several millennia? Or is there something about it, like stone working techniques, that made it independently accessible to the human mind in diverse cultures and civilizations? Personally, I believe the geometry was discovered independently by widely disparate cultures. Why? Because this type of proportional geometry originates with the circle, one of the most popular and multi-cultural symbols in the human world. It is a shape that served as a foundation for countless domestic and ceremonial structures. Given the intimate relationship between the circle's radius and the hexagon, it is an argument I can live with, for now. This opinion does not exclude instances of cultural diffusion within specific geographic regions.

    Origami Mathematics
    These pages are an attempt to begin collecting information on the mathematics of paper folding. Anyone who has practiced origami has probably, at one time or another, unfolded an origami model and marveled at the intricate crease pattern which forms the "blueprint" of the fold. Clearly there are some rules at play in these collection of creases. Clearly there is an origami geometry at work when paper is folded. Unfortunately, much of the above-mentioned work is new, and at the time of this writing there are few good references for this type of information. These pages will try to help solve this problem by providing an extensive bibliography for origami-math, list upcoming lectures and events, and offer instructions and tutorials for select topics. However, this is an on-going project! These pages are still in their infancy, and any comments or suggestions (or offers to help!) would be greatly appreciated! In March of 2001 the 3rd International Meeting of Origami Science and Technology (3OSME) was held. See the above link for the program listing, pictures, and information on the proceedings book

    40. Ricci: A Mathematica Package For Doing Tensor Calculations In Differential Geome
    A Mathematica package for doing tensor calculations in differential geometry and general relativity.
    A Mathematica package for doing tensor calculations in differential geometry
    Version 1.37
    Last Updated November 12, 2002 Ricci is a Mathematica package for doing symbolic tensor computations that arise in differential geometry. It has the following features and capabilities:
    • Manipulation of tensor expressions with and without indices Implicit use of the Einstein summation convention Correct manipulation of dummy indices Display of results in mathematical notation, with upper and lower indices Automatic calculation of covariant derivatives Automatic application of tensor symmetries Riemannian metrics and curvatures Differential forms Any number of vector bundles with user-defined characteristics Names of indices indicate which bundles they refer to Complex bundles and tensors Conjugation indicated by barred indices Connections with and without torsion
    Limitations: Ricci currently does not support computation of explicit values for tensor components in coordinates, or derivatives of tensors depending on parameters (as in geometric evolution equations or calculus of variations), although support for these is planned for a future release. Ricci also has no explicit support for general relativity, or for other mathematical physics or engineering applications, and none is planned. If you are interested in such support, I recommend that you consider the commercial package MathTensor, which is far more extensive than Ricci, and provides all these capabilities and more. MathTensor is available from
