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 291
MathLinks Math Forum
This site is an online forum for those interested in mathematical Olympiads (at all levels). The main aim of the site is to help gifted mathematics students improve their problem solving skills.
Knot 290
The Wolfram Function Site
From the site: "Providing the mathematical and scientific community with the worlds largest collection of formulas and graphics about mathematical functions." As of December 26, 2005, there were 87,160 formulas and 10,828 visualizations of functions.
Knot 289
20,000 Math Problems
This site "contains exactly 20,000 problems from 38 journals and 21 contests, all published before 1990." Happy problem solving!
Knot 288
Mathematical Fiction
Alex Kasman's site devoted to mathematical fiction. He has compiled details on many significant references to mathematics in fiction.
Knot 287
Archimedes Palimpsest
Archimedes palimpsest, the oldest surviving manuscript containing the work of Archimedes, is now housed at The Walter's Art Museum. The palimpsest contains the only known extant copy of Archimedes' ``Method of Mechanical Theorems''. At this site you can: learn about Archimedes, one of the great mathematicians of antiquity; find out the history of the palimpsest and how it was discovered; and best of all, get a glimpse at some of the pages of the palimpsest.
Knot 285
Archimedes' Laboratory
Archimedes' Laboratory is dedicated to showing how geometry can be fun through visual creativity. It includes interactive puzzles that range in complexity and challenge the problem solving capabilities of the mind.
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The address we have for this site is no longer valid.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.
