Recreational mathematics
and fractal graphics
continue to stimulate the mind and foster student interest in mathematics. Some favorite authors & books in this area include:
Martin Gardner's books
(like The Colossal Book of Mathematics and The Night is Large),
Cliff Pickover's books
(like The Mathematics of Oz and The Zen of Magic Squares),
Calvin Clawson's Mathematical Mysteries,
Ian Stewart's books
and puzzles,
and
Ivars Peterson's writings (like Islands of Truth).
What are your favorite books and web sites
in this area for stretching
the mind and eye?

Arcadia, the Tom Stoppard play I'm going to be in (Bloomsbury Theatre, London, 14-16 November!) is largely about fractals and iterative algorithms. It's also incredibly funny.

One of my favs has always been Burlekamp's Dots and Boxes: Sophisticated Childs Play. It's a mathematical breakdown of the dots and boxes game I'm sure everyone has played at least once in their life. I'm a big fan of all of Burlekamp and Conway's stuff though (If you want some good Conway stuff, pick up On Numbers And Games or Winning Ways For Your Mathematical Plays

Just as a side note, the field of Recreational Mathematics was started by Roger Penrose, who you may know from "The Emporer's New Mind" fame. He created the Penrose tesselation which once again, you've probably seen but I can't find a link to that the moment. Many of his tesselations are now available as puzzles, which are sold at Pentaplex.

if anyone is interested in gödel, formal languages, and modern set theory (who knows - maybe someone is!) i think i've found the perfect book - discovering modern set theory (part 1 - the basics) by just and weese. you need a basic maths background (eg i have a degree in physics), but it is very nicely written (it's based on lectures, with many comments and jokes addressed to the reader) and (so far - i've only had it a day or two) pretty clear.

(i know this isn't exactly recreatoinal maths, but it's fascinating, and deeply important, stuff)

Metamagical Themas : Questing for the Essence of Mind and Pattern by Douglas R. Hofstadter is good.

Another of my favorites is Gödel, Escher, Bach: An Eternal Golden Braid,

also by Hofstadter. Linking the 3 was pure genius. I've read it twice and would read it a third time, if I could find my frayed copy.

[self link] - i wrote a little python package for creating parquet deformations like those described in metamagical themas. it's not very good - i would do it differently now - but anyone who read the book might be interested.

I recently read Ian Stewart's book about zebra stripes and the shape of snowflakes. The knowledge you need to explain these shapes is immense: fractals, symmetry breaking, turbulence, etc. Great book. I also loved his book with Pratchett and Cohen (the Science of Discworld), which I consider one of the best (and funniest) accounts of 'holistic science'. The sequel was not quite as good.

I'll second/third the recommendations for Hofstedter's works (GEB and MT). I've tried to describe GEB to those that have never heard of it, and failed miserably. Anyone here have a good, concise way of describing the wonder, breadth and scope of that work?

any description should include the word "whimsical" (if only because, if you don't like whimsy, it's a rather trying read).

One of the best and most comprehensive math books out there is

On preview: this may be the book you are looking for, trharlan. I enjoy mathematical ideas, but never excelled in it in school and am definitely a layperson when it comes to math, but I have enjoyed the book both as entertainment and as a reference.

*Mathematics: From the Birth of Numbers*by Jan Gullberg, a Swedish surgeon. It has everything from the history of numbers and counting to detailed explanations of fractals and topolgy. Well worth a look, although at 1200 pages, it is hardly something to breeze though at the beach.On preview: this may be the book you are looking for, trharlan.

*subsets*of mathematics. The theories that Hawkings and others describe are essentially mathematical, and chaos theory is a field of specialization within mathematics. Your question is similar to, "I understand football and baseball, why can't someone explain*sports*?"posted by gleuschk at 12:06 PM on November 1, 2002

There's a few really good ones out there. Simon Singh's Fermat's Enigma has been mentioned already. George Ifrah's The Universal History of Numbers is a relatively easy-to-read survey (and a good reference). Charles Siefe's Zero was a surprisingly fun book to read. Tobias Dantzig wrote a really good one about numbers, but I think it's out of print, unfortunately.

I'll add another voice in encouragement for Goedel Escher, Bach. It was one of the most thought-provoking books I've ever read. It's also a lot of fun.

Chaos is another good book on match.

Another book that is on mathematics, but without covering any specific area, is G.H. Hardy's A Mathematician's Apology. It would perhaps be better to call it a book about the philosophy of pure mathematicians than actual math, but it's nevertheless an interesting insight into the field as a whole.

An old but fun book The Eight by Katherine Neville. Not very mathematical, but interesting how math is woven into the plot.

[self link] I've written an app to wrap six arbitrary images onto a hexaflexagon (as mentioned in the Colossal Book Of Mathematics). A fun way to carry around pictures.

People here don't seem to be mentioning websites and there are a vast number of great ones. Here are some that I keep handy. The de facto standard is MathWorld, although it is more of a mathematical dictionary than a place to explore new concepts. Knot a Braid of Links can send you to many sites that don't assume technical knowledge, but are on interesting subjects like the mathematics used in 17th century war or, my favorite, topological lego structures. If set theory (or quantum logic) is more your style, Metamath should be sufficient to keep you for a while, although it can get hard to follow due to lack of prose. (Gotta love the proof that x=x) Finally, for a mix of random topics explained in good detail (including relations to physics) and understandable to anyone with a slight background in calculus, try MathPages.

A good book for the armchair mathematician is Innumeracy by John Allen Paulos, who's also written a few other engaging works in the same vein. This one discusses how people are very poor at handling basic mathematical concepts, which inhibits their ability to understand budgets, manage projects, and compare practical risks. How much is a trillion? What happens if you double the width and length of a farmfield (answer: you quadruple your expenses)? Which is more dangerous, an airplane ride, or jaywalking to drop off a letter?

I don't know a better way to explain GEB than "an accessible yet challenging overview of the intimate relationships between mathematical theory, artistic perception, and human creativity" -- or "the perfect gift for the geek in the family".
