|Geometry from the land of the Incas|
A Peruvian site with Euclidean geometry problems accompanied by proofs, animation and sound (Poncelet, Napoleon, Eyeball, Steiner, Carnot, Sangaku, Morley, Langley and the Butterfly Theorem) as well as Inca Geometry (Cuzco, Machu Picchu, Incan Quipu, Nazca Lines, Lord of Sipan).
SingSurf is an online applet for creating 3D models of algebraic surfaces. It allows you to rotate and scale the surfaces, and it contains a visual index to most of the famous algebraic surfaces.
The address we have for this site is no longer valid. If you can help in locating this page, please contact us.
This site includes a description of the Anti-Divisor, which you can think of as a cousin of both prime numbers and of divisors. See Perry's other maths pages too.
|Nick's Mathematical Puzzles|
Over 60 puzzles selected for the deceptive simplicity of their statement, or the elegance of their solution. They range over geometry, probability, number theory, algebra, calculus, and logic. All require a certain ingenuity, but usually only pre-college math.
This page contains applets that calculate the partions of n and discusses some interesting patterns that can be found.
|Probability by Surprise|
A nice collection of probability applets (including the Birthday problem, Banach's matchbox, and Traffic Jams); they may seem simple at first but they're always surprising...
This AMS site offers electronic brochures that are intended to promote appreciation and understanding of the role mathematics plays in science, nature, technology, and human culture.
A collection a beautifully drawn curves. Some take awhile to unfold, but they are worth waiting for.
|The Poly Pages|
This site provides extensive information on the various polyforms: poly-ominoes, -iamonds, -hexes, -cubes etc.
An on-line version of Edwin Abbott's famous novel: Flatland, A romance of many dimensions. This is a geometrical story about a two-dimensional square who visits one- and three-dimensional worlds.
