Product Description
From Amazon.co.uk
For years Ian Stewart has been wrestling with the mathematical underpinnings of the natural world. In his new book What Shape is a Snowflake? he explains his fascination with nature's numbers and explores the fruits of his quest so far. No, wait! There isn't a single equation in the book--honest.
Stewart starts with a general exploration of patterns in nature--six-pointed snowflakes, feathery patterns of frost on glass, zebra stripes, ripples in the sand, honeycombs, spirals, and so on--then attempts to illustrate, in words, the mathematical principles underlying them. In the process the reader is introduced to ideas of dimensionality, symmetry in all its manifestations, patterns of tiling and packing, symmetry breaking, fractals, complexity theory and chaos. In the penultimate chapter he goes on to explain how the mathematics of earthly nature may mirror that of the universe. Finally he addresses the question of the book's title: What shape is a snowflake? You may be disappointed with the answer, but only if you don't get the joke.
Snowflake is a fascinating read, though it does requires a bit of patience. Much space in the first half of the book is given over to introducing patterns without offering many clues as to what generates them. In consequence, I found myself skipping sections to get to the juicier bits towards the end. Still, for the numerically challenged but patient reader, Snowflake is as friendly an introduction to the mathematics of nature as you could wish to find.--Chris Lavers

A Universe Full of Mathematics, Nov 6 2001
By R. Hardy "Rob Hardy" - Published on Amazon.com
This review is from: What Shape is a Snow Flake?: Magic Numbers in Nature (Hardcover)
In _What Shape is a Snowflake? Magical Numbers in Nature_ (W. H. Freeman), Ian Stewart has managed to write a wonderfully comprehensive and colorful mathematical tour of the universe from top to bottom without putting a single equation into his book. In fact, there aren't really many numbers. He gets to show what happens when a mathematician looks at the infinite aspects of the world. He writes, "I am a mathematician. I experience these wonders through a mind that has spent a lifetime learning how to detect patterns, how to understand patterns, how to find new patterns... I stand on the shoulders (and lean on the elbows) of giants, on five thousand years of mathematical history that has been groping toward such understanding. I see what all humans see, and in a few respects perhaps I see more. I see clues to rules, laws, regularities."The snowflake is key to his tour, and there is plenty to learn specifically from it, but since Stewart is keen to draw on patterns all over the place, the range of his book is amazing. In well connected chapters, looking closely at snowflakes takes him to the leafy patterns of frost on the window, the organization of leaves around spirals and Fibonacci numbers, the spiral of the nautilus shell, the stripes and amazing triangle patterns on other sea shells, the patterns of stripes on zebras and fish, the grooves in sand dunes and the lines of dunes themselves, the lines a sidewinder leaves in the sand, the synchrony of a millipede's legs and a horse's at different gaits, the oscillations of the legs of robots, the ups and downs of animal populations, the chaotic variations of weather and of the planets in the solar system, and the shape of the universe. It is clear that Stewart sees connections everywhere, and is only using the snowflake as an excuse to look at the foundations of physical laws, the nature of time, space, and matter, and why patterns in one field give clues to patterns in something entirely different. "I'm going on a journey in search of the snowflake's secret," he says, "and, with it, the deeper secrets of our astonishing universe. And you're coming with me." It's a beguiling invitation from a masterful guide.
Naturally a tour of this type, with all it encompasses, is not going to be long on detail, and anyway, one would have to start getting into equations for that. There is a useful list for further reading at the back of the book, for those who insist on stronger doses of such stuff. Stewart's book, however, is an exhilarating, accessible, vividly illustrated voyage through classic and current mathematical ideas. By the end of it, a reader will understand that the snowflake's shape is determined by phase transition, bifurcation, symmetry-breaking, chaos, fractals, and other complexities. Oh, and the book does eventually reveal what shape a snowflake is.

Required reading for everyone learning math., Aug 23 2005
By Joseph Biskup - Published on Amazon.com
This review is from: What Shape Is A Snowflake? (Hardcover)
Rob Hardy's review is an excellent summation of this excellent book. "What Shape is a Snowflake?" is a book about the big picture, about the meanings behind and the connections between big ideas. This book is not about details of applying or calculating under these frameworks. As has been stated before, this is an excellently illustrated and formatted book. The pictures and text dance with each other, nicely balancing and building interest in each other.
As Mr. Stewart says, he sees mathematics and beauty as attached ideas and this book is an effort to show the beauty of mathematics. "Most people's mental image of mathematics is page upon page of complicated `sums' - not an especially beautiful sight. I sympathize, believe me. But that's arithmetic, not mathematics (I'm quite passionate about this). Those symbols on the page come no closer to the subject's true beauty than the staves and semiquavers of musical notation come to a Beethoven symphony." As such, this is definitely a book about mathematics and definitely not about arithmetic. There are many references in the book to original publications and theories, and there is a short section at the end for further reading so anyone who wants more detail has a place to start looking. For me this book provided a clear and concise description of the ideas at the foundation of various mathematical principles. Mr. Stewart focuses his book on patterns and their implications. He talks about the different dimensions, scale, and symmetry of patterns, he talks about bifurcation, fractals, chaos, randomness, complexity and phase transitions. He also showed how these ideas and principles thread their way through literally everything in the universe.
This book should be approachable for any child in junior high or high school. Additionally, I think it is an excellent introduction for any adult interested in understanding the world around us.

Mathematics deserves four colour, July 18 2002
By "thirteenthfairy" - Published on Amazon.com
This review is from: What Shape is a Snow Flake?: Magic Numbers in Nature (Hardcover)
I must admit I was looking for more detail from this book than it contains. I was looking for more detail on hexagonal systems.Instead there is less detail and less formal mathematics. I found it to be rather similar to other publications by Ian Stewart, such as the book Fearful Symetry which contains many of the same ideas.
Despite my personal desires I am glad to see that Ian has finally been granted lots and lots of expensive four colour illustrations with which to explain how interesting mathmatics really is.
I immediately found a use for it in the workshops I run for children. It is the best illustrated book Mr Stewart has yet produced.
Listmania!
