## 'A lifetime of puzzles', 'Homage to a pied puzzler' and 'Mathematical wizardry for a Gardner'

*There has been a recent spate of books in honour of Martin Gardner, who has spent over half of his 95 years entertaining us with his recreational mathematics. Matt Parker reviews three of the latest.*

Martin Gardner is widely regarded as having started and popularised the area of modern recreational mathematics. Born in 1914, he began his career as an amateur magician, publishing his first magic article in 1930. His strong interest in mathematics lead him to submit an article about flexagons to *Scientific American* in 1956, starting the *Mathematical Games* column that he
contributed regularly for the next 25 years. During this time he also became a highly influential magician, spending a lifetime turning magicians into mathematicians and mathematicians into magicians.

Gardner's followers from both the mathematics and magic communities get together biennially at what are called the *Gatherings for Gardner*. Started in 1993, the eighth *Gathering for Gardner* was in 2008, with the tenth being planned for 2010. At these gatherings ideas from mathematics, puzzles and magic are discussed, following in the vein of the topics and areas first presented by
Martin Gardner. The initial 1993 meeting was the idea of Tom Rodgers who is still involved with the *Gatherings* and is an editor on all three books being reviewed here.

All three books follow the spirit of the *Gatherings* in that they are collections of articles written by people who were inspired by Gardner. They cover an eclectic range of topics bound together by a hunger for mathematical playfulness — how many circles can you pack into a square, how many colours does it take to colour a torus, and what happens when you play word games on the platonic
solids are just some of the questions examined. Some articles in the books are backward looking, examining historic puzzles or mathematical problems, while others develop and explore puzzles first posed by Gardner.

*Homage to a pied puzzler* and *Mathematical wizardry for a Gardner* are companion publications by the same editors and are effectively the proceedings from the seventh *Gathering*. To a novice, reading these books may feel a bit like arriving late at a party where everyone already knows each other. The books assume quite a lot of background knowledge and they're not afraid of
being a little self-indulgent. Opening sentences like "Since 1983 I have been researching quasi-periodic patterns based on the Fibonacci Lattice..." may have you wondering if you've missed the beginning of the conversation, while intros like "In this article, I will recount experiences with fellow dancers using giant tangrams as props to create dances..." may make you wonder why you're even in
the conversation at all.

*A lifetime of puzzles* has a slightly different list of editors and is a collection of articles commemorating Martin Gardner's 90th birthday in 2004. While the level of maths in these articles is a bit more advanced than in the other two books, *A Lifetime of Puzzles* covers the same erratic spectrum, from almost academic papers to anecdotal stories about puzzles.

Now, if you're already familiar with Martin Gardner's work and are feeling annoyed by my slightly derisive tone, then these are the books for you. I'm a huge fan of Martin Gardner — in fact I'm one of the countless mathemagicians who list him as their main inspiration — and I loved trawling through these books for new ideas and intriguing puzzles to try. In my opinion, all three books are
worth a read (but if you go for just the one, I'd recommend *Homage to a pied puzzler*, which I found the most interesting, albeit by the smallest of margins).

*Scientific American*columns. His 1956 classic

*Mathematics, magic and mystery*, despite being a little archaic in language and tone, is the perfect place to start.

But if you have already read Gardner's work and you're eager for more, then any one of these books will get your flexagon-shaped heart racing.
