Mathematical Recreations
Number theory, tilings, symmetry groups, knots, mathematical games, magic squares - these are just some of the intriguing subjects of the sites listed here. Whether or not you are a mathematician, you will find plenty to stimulate the mind - and plenty too that is esthetically pleasing.
- Bamdad's Math Comics Page
- On the lighter side ... a splendid collection of math related comics and cartoons.
- Clever Games for Clever People
- How to play games taken from John Conway's book "On Numbers and Games" - Stop-Gate, Col, Snort, Coin-strip, Moneybags, Kayles, Rim, Rayles, Traffic Jam, Welter's Game, All the King's Horses, Digital Deletions, Hackenbush Unrestrained, Hackenbush Restrained, Hackenbush Hotchpotch, Technicolor Hackenbush
- The Fibonacci Numbers and the Golden Section
- The University of Surrey Home page for information about the Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13,... and also its related mathematical objects: the golden section +/- 0.61803 39887... or +/- 1.61803 39887... and the golden string 1 0 1 1 0 1 0 1 1 0 1 1 0 ...
- The Geometry Center
- A treasure-house of geometrical resources for teachers, students and general enthusiasts.
- Ivars Peterson's Mathland Archives
- A tremendous resource with articles about pi, magic squares, random walks, fractals, map-coloring, primes, and much, much more.
- The KnotPlot Site
- A collection of knots and links, viewed from a (partly) mathematical perspective. The images here were created with KnotPlot, a program to visualize and manipulate mathematical knots in three and four dimensions. Feast your mind and feast your eyes with some of the images in the picture gallery.
- Largest Known Primes
- By Chris P. Caldwell.
- The MacTutor History of Mathematics Archives
- A wealth of fascinating information.
- Magic Squares
- By Suzanne Alejandre. Part of The Math Forum
A Virtual Center for Math Education on the Internet A wealth of information, not just for use in schools. - Mathematical Games and Recreations : a History
- Part of The MacTutor History of Mathematics Archives.
- Mersenne Primes: History, Theorems and Lists
- By Chris P. Caldwell. Includes table of known primes, conjectures, unsolved problems, etc.
- Mike Keith's World of Words, Numbers, and Notes
- An awesome web site of mostly original diversions in the areas of mathematics, word play, and music. Among the topics covered you will find: queens attacking prime numbers on knight's tours, a demonstration that all numbers are interesting, fun facts about the calendar, wild narcissistic numbers, the wacky world of dottable fractions.
- Penrose Tiler
- A preliminary version of a Java applet by Geert-Jan van Opdorp to create and investigate Penrose Tilings. It uses Kites and Darts (Conway's terminology) but can show them as rhombi. You can have fun generating, building and subdividing Penrose tilings, using a library of starting configurations ("Sun", "Batman",etc.). Non-mathematicians can just enjoy playing with the patterns.
- Recreational & Educational Computing (REC)
- REC - which is short for Recreational & Educational Computing - is a publication devoted to computer recreations & 'mathemagic'. REC is edited and published by Dr. Mike Ecker, a Penn State math professor, and is about puzzles & teasers, programming (BASIC, some Pascal, a little C?), math, letters, graphics, fractals, challenges, recreation, reviews, word-play, humor, tips, solutions, and the editor's own concept of "Mathemagical Black Holes" (similar to attractors).
- The Uselessness of Pi and its irrational friends
- A constant source of information and entertainment!
- Where Is Your Birthday in Pi?
- Find where your birthdate or any other string of digits occurs in Pi.
