Knot 359
Random numbers
A simple explanation how computers generate random numbers.
Knot 358
This is a website for and by students. Polyominoes is the general name given to plane shapes made by joining squares together. Enjoy the recreational mathematics !
Knot 357
Category Theory Demonstrations
These are Web-based interactive demonstrations in category theory. I'd like suggestions from teachers and learners about whether they're useful, and what to add. So far, the demos include set products and coproducts and their "universal property". They also demonstrate the idea that it isn't the internal content of the product that makes it a product, but its relationship to the structures around it.
Knot 356
Mr. Schlytter's Mathematics Site
Enjoy these exciting interactive math activities for student success.
Knot 355
Mathematics Online Tutor
Mathematics Online Tutor is a math tutorial which is being used in schools throughout the United Kingdom and is being introduced in Canada.
Knot 354
Wild About Math!
Wild About Math! is a blog dedicated to making Math fun and accessible. It contains articles, math contest problems and mathcasts (videos about math).
Knot 353
Big Ideas
The Big Ideas site carries articles about mathematics, logic and philosophy (and other topics) that are intended to be accessible to non-specialists. It includes "mini-series" that aim to introduce some basic ideas of college-level mathematics to readers with no mathematical training.
Knot 352
Good math, bad math
Good math, bad math is a blog about finding the fun in good math and squashing the bad math and the fools who promote it.
Knot 351
Fractal forums is a forum for Fractal related discussion. Share your own fractal images and fractal movies with us. Discuss fractal theory, IFS, Mandelbrot sets and any forms of fractal art!
Knot 350
Prime structure
A novel method has been devised to add structure to the sieve of Eratosthenes, expressible by a simple recursive formula. Surprisingly, this new formula can generate not just one, but an infinite number of distinct, yet related, prime structures.
