› Find signed collectible books: '200% of Nothing: An Eye-Opening Tour through the Twists and Turns of Math Abuse and Innumeracy'
If you know the difference between lies, damned lies, and statistics, give a copy of A.K. Dewdney's 200% of Nothing to your friends to get them up to speed. If you don't know the difference, consider this funny, engaging little book a crash course in numeracy, the mathematical equivalent of literacy. Opening with two chapters on the importance of this dying talent, Dewdney (formerly Scientific American's "Mathematical Recreations" writer) spooks the reader with real examples of government agencies, media outlets, and--of course--car salesmen deceiving their audiences with beguiling mathematical sleights of hand. It's all too easy for us to think we're immune to such tactics until we actually see them laid out for us in prose as clear and disarming as Dewdney's. From these tactics he delves more deeply into practical examples of particular problems that often catch us unaware. Gambling, advertisements using bizarre-but-normal-looking charts, and bad science all come in for thorough examinations, and the reader is amazed and occasionally angered at the shamelessness of the purveyors of misleading statistics. The book closes with two chapters designed to make readers "mathematically streetwise," with exercises to help you grasp ratios, very large and small numbers, and probabilities more intuitively. 200% of Nothing inspires learning and makes it interesting--if you want to see through the fog of numbers surrounding politicians and advertisements, there's no better place to start. --Rob Lightner

Starting with an elegant description of a small piece of land called Hungry Hollow, A.K. Dewdney introduces us to its denizens. The reader goes on a guided tour through the many dimensions of our natural habitat, back into prehistoric time and inward to a teeming microscopic world full of strange creatures performing bizarre feats.
"It surprised me how 220 pages explaining biological phenomena can add up to a literary image of the magic of lifePerhaps this book will go some way to redress the general deficiency in judgement that allows humans to endanger other life forms..." -NEW SCIENTIST

› Find signed collectible books: 'A Mathematical Mystery Tour: Discovering the Truth and Beauty of the Cosmos'
This is a thought-provoking book that entertains, makes you smile, and opens your mind to intriguing questions about the cosmos, truth and the nature of mathematics. You'll finish this book having had a number of those delightful "aha! experiences", in which a new insight is obtained or half-understood ideas fall into place. It is a book about the history and philosophy of mathematics that it is written in a very enjoyable style. Once started, you'll not want to put it down.
The author takes the reader on a quest for answers to the questions: Why is mathematics so useful in science? Is mathematics discovered or created? He recounts fictional visits to the cities of Miletus, Aqaba, Venice and Oxford. From quirky specialists he learns about a host of intriguing subjects, including the mathematics of Pythagoras, amicable numbers, the Arab world's invention of algebra, atomic theory, metamathematics and models of computation. The travelogue format of the book is charming. Parts of the book with appeal to lovers of science fiction or of Jorge Luis Borges, and there are some subtle good jokes. At the same time, the discussions of group theory and mathematical logic are solid mathematics and amongst the most digestible and entertaining introductions to those subjects.
There are important mathematical and philosophical ideas in these 200 pages, and they are made accessible to anyone aged 16 or more who is interested in mathematics or science. The quest is concerned more with questions than answers. The author has written other acclaimed mathematics and science books. After reading this one, you'll want to read all the others. --Richard Weber

› Find signed collectible books: 'Palniverse'
The year is 1981, and in the computer lab of a large university a group of graduate students and their professor are hard at work on their mainframe, graphically modeling an imaginary two-dimensional world. The project is going well, extraordinarily well, when one student suddenly notices that the world they are building with their graphics program is . . . inhabited! So begins A.K. DewdneyÕs newly republished 1984 tale of trans-dimensional discovery and communication. The students and their professor find, to their astonishment, that they are communicating with Yendred, their only contact in the 2D world of Arde. At first disbelieving, they are soon entranced by a universe in which astonishing tiny creaturesÑindeed an entire astonishing worldÑexist solely on an x-y plane. This book, following in the footsteps Edward AbbotÕs nineteenth century classic Flatland, is a cult favorite among mathematicians and computer scientists. As a kind of mental puzzle or brain-teaser, it challenges and delights, inviting readers to imagine just how a two-dimensional world might work. But the book is also a parable, serving as a cautionary tale about the difficulties of communication from one totally alien world to another, and suggesting that it is not only two-dimensional Ardeans who fail to see beyond the the obvious world before their eyes.

› Find signed collectible books: 'Yes, We Have No Neutrons: An Eye-Opening Tour through the Twists and Turns of Bad Science'
A.K. Dewdney is well-known to readers of the Scientific American as their former "Mathematical Recreations" columnist. Here he acts as a well-placed professional terrier who has assigned himself the task of sniffing out the rats in the scientific closet and giving them a good shaking. By Dewdney's definition "science" is a big cupboard which includes the social sciences. And he clearly relishes the all-encompassing breadth of his task, which is not to rubbish science--far from it--but to serve warning on slipshod science and its practitioners. Even Nobel Prizes do not give immunity, as Fleishmann and Pons will learn if they care to read this fascinating book. Indeed, every scientist (of both the hard and soft variety) should be given a copy as a reminder of some basic home truths, such as the necessity for reproducibility of results, and as a warning against the lure of instant fame.
As Dewdney writes, "when science goes wrong all hell breaks loose ... the public grows confused [and] sceptical about the scientific process.&" His sample of scientific transgressions runs from the hard science of Blondot's turn-of-the-century "discovery" of N- rays, through the soft science of IQ tests and Freudian psychoanalytical theory, to SETI (Search for Extraterrestrial Intelligence), neural nets, cold fusion (the Fleishmann and Pons story), Biosphere 2 and J. Phillipe Rushton's racial theory as proposed in his book ,The Bell Curve: Intelligence and Class Structure in American Life. Most of his victims are in the soft sciences, perhaps because Dewdney feels that most damage is caused in this area, since they generally make for more media-friendly stories, or maybe just because they are easier targets. Freud may have grossly over-interpreted at times, but recent research on mother/offspring influence supports his Oedipal complex theory and it would be interesting to know what Dewdney thinks of these results.
Dewdney's experience as a professional science writer shines through, making this book a joy to read, and there is a helpful index and bibliography. Finally, as he warns any would-be star of science, "if there are dreams of glory, real scientists keep them, trembling, in the background." -- Douglas Palmer
