› 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 [via]

› Find signed collectible books: 'Flatland: A Romance of Many Dimensions'
Flatland is one of the very few novels about math and philosophy that can appeal to almost any layperson. Published in 1880, this short fantasy takes us to a completely flat world of two physical dimensions where all the inhabitants are geometric shapes, and who think the planar world of length and width that they know is all there is. But one inhabitant discovers the existence of a third physical dimension, enabling him to finally grasp the concept of a fourth dimension. Watching our Flatland narrator, we begin to get an idea of the limitations of our own assumptions about reality, and we start to learn how to think about the confusing problem of higher dimensions. The book is also quite a funny satire on society and class distinctions of Victorian England. [via]

› Find signed collectible books: 'A Mathematical Mystery Tour: Discovering the Truth and Beauty of the Cosmos'
A.K. Dewdney takes readers on a theoretical world tour to answer the question: Did humans make up mathematics, or did mathematics make up everything, including humans? After all, mathematical formulas seem to perfectly govern the cosmos, and the ur-mathematician Pythagoras himself believed that mathematics makes up reality. Dewdney has taken it upon himself to examine this fundamental question, beginning his journey in Miletus, the ancient home of Pythagoras and other deep thinkers. There, he meets the fictional Dr. Petros Pygonopolis, the first of his guides through space and time in search of mathematical meaning in history. His journey continues with stops in the Arabian desert (for insight into ancient Islamic astronomy with Professor al-Flayli), Venice (where Maria Canzoni reveals the mysteries of atomic theory), and England (home of the "engines of thought" in the form of Alan Turing's mind machines, as explained by Sir John Brainard). Dewdney's style is accessible, his knowledge is thorough, and his sense of humor is refreshing, if a bit geeky. A Mathematical Mystery Tour is not a difficult read, although the ideas it attempts to clarify are quite abstract. The fictional tour guides at each port of call are helpful in humanizing the intimidating subject matter. --Adam Fisher [via]

› Find signed collectible books: 'Yes, We Have No Neutrons: An Eye-Opening Tour Through the Twists and Turns of Bad Science'
"Cold fusion" has become an oft-used synonym for science gone wrong, but as A. K. Dewdney colorfully explains in Yes, We Have No Neutrons, that bad science has a long and (un)distinguished history. Predicating his discussion on Langmuir's "Laws of Bad Science," which describe common characteristics of dubious scientific claims, Dewdney recounts such classic scientific blunders as the "discovery" of N-rays by Rene Blondlot, psychoanalysis as practiced by Sigmund Freud, and even the ill-fated Biosphere 2 experiment. (Yes, cold fusion is there too.) Dewdney's book will sharpen the mental razor of anyone who hopes to separate legitimate claims from bunk. [via]
