Browsing previous knots in the braid

Below is a list of all the links collected by KaBoL since it first started in 1996, in reverse chronological order. If you are looking for something specific, you might want to try our search engine.

Knot 284
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).
Knot 283
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.
Knot 282
The Anti-divisor
The address we have for this site is no longer valid.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.
Knot 281
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.
Knot 280
Partition calculators
This page contains applets that calculate the partions of n and discusses some interesting patterns that can be found.
Knot 279
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...
Knot 278
Mathematical Moments
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.
Knot 277
Famous Curves
A collection a beautifully drawn curves. Some take awhile to unfold, but they are worth waiting for.
Knot 276
The Poly Pages
This site provides extensive information on the various polyforms: poly-ominoes, -iamonds, -hexes, -cubes etc.
Knot 275
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.
