**Dissections: Plain and Fancy**

by Greg N. Frederickson

This is a fun book to explore. The art of dissection goes all the way back to the age of Plato. Since the subject matter is the slicing and splicing of geometric figures, most of the results are presented as diagrams, making the solutions easy to understand. Additional puzzles are interspersed throughout the text and solutions to all are included at the end of the book. There is also lots of history, literary tidbits, and biographies of nearly 50 contributors to the field of dissections plus Frederickson's accounts of his own discoveries, and how he came to make them. This is an essential book for anyone interested in geometric dissections.

**Elegant Universe**

by Brian Greene

Superstrings, the quest for the ultimate theory. As currently formulated, general relativity and quantum mechanics cannot both be right."Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet these theories cannot both be right under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that these two pillars of physics can be reconciled in superstring theory, a theory of everything."

It hasn't all been worked out yet, but despite the uncertainties "string theorists work to find approximate solutions to approximate equations". Greene gives the non-specialist at least an illusion of understanding or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge.

**Fermat's Enigma : The Epic Quest to Solve the World's Greatest Mathematical Problem**

by Simon Singh & John Lynch

When Andrew Wiles of Princeton University announced a solution of Fermat's last theorem in 1995, it electrified the world of mathematics. After a flaw was discovered in the proof, Wiles had to work for another year (he had already labored in solitude for seven years) to establish that he had solved the 350-year-old problem. Simon Singh's book is a lively, comprehensible explanation of Wiles's work and of the star-, trauma-, and wacko-studded history of Fermat's last theorem. The book also contains some problems that offer a taste of the math, but it also includes limericks to give a feeling for the goofy side of mathematicians. An engrossing page turner for the mathematically inclined.

**Flatland: The Classic Speculation on Life in the 4th Dimension Sphereland: A Continuing Speculation on an Expanding Universe (2 books in 1)**

by Abbott, Burger, & Asimov

Flatland is a reprint of a classic essay on the fourth dimension, first printed in 1884. It is a novel that imagines a two-dimensional world inhabited by sentient geometric shapes who think their planar world is all there is. But one Flatlander, a Square, discovers the existence of a third dimension and the limits of his world's assumptions about reality. Thus, he comes to understand the confusing problem of higher dimensions. The book is a satire on society and class distinctions in Victorian England. **Sphereland** published 60 years later, revisits the world of Flatland in time to explore the mind-bending theories created by Einstein, whose work so completely altered the scientific understanding of space, time, and matter.

**Flatterland: Like Flatland, Only More So**

by Ian Stewart

With Flatterland, Ian Stewart, an amiable professor of mathematics at the University of Warwick, updates the science of Flatland, adding literally countless dimensions to Abbott's scheme of things. Along his fictional path, Stewart touches on Feynman diagrams, superstring theory, time travel, quantum mechanics, and black holes, among many other topics. And, in Abbott's spirit, Stewart pokes fun at our own assumptions, including our quest for a Theory of Everything. And, best of all, you can learn a thing or two about modern mathematics while being roundly entertained. That's no small accomplishment.

**Geometry, Relativity, & the 4th Dimension**

by Rudolph V.B. Rucker

The author wrote: "My goal has been to present an intuitive picture of the curved space-time we call home. There are a number of excellent introductions to the separate topics treated here, but there has been no prior weaving of them into a sustained visual account. I looked for a book like this for many years- and finding none, I wrote it." His book is an excellent introduction to the subject of the curvature of space time and special relativity. The book is basic enough to be understandable (at least to a degree) by any intelligent (and determined) adolescent, but deep enough for the physics or math undergraduate and perhaps even the graduate student. Rucker has a way of introducing complex ideas in a rather simple fashion so that one doesn't often realize how deep the subject matter is at first. Unlike some of his other books, however, considerable math background is required and a substantial amount of effort on the part of the reader will be necessary. All the same, the book is a very interestting venture into the world of geometry and relativistic physics.

**How the Other Half Thinks: Adventures in Math Reasoning**

by Sherman K.Stein

This is a well written and much needed book. Of all the disciplines, mathematics continues to be the least understood by the general public. Even among the scientists who use mathematics daily in their work, many are not fully aware of the true nature of the subject. One of the main reasons for this lack of familiarity is the absence of books that illustrate the mathematical way of thinking in a way that non-mathematicians can easily comprehend.

The author emphasizes the creative element of mathematics by exploring some significant mathematical discoveries through simple, intuitive manipulations. With an ingenious technique that uses no algebra or trigonometry, and only a minimum of arithmetic, Stein takes us through the thought process behind some of math's great discoveries and applications. Each chapter begins with a simple question about strings made up of the letters a and b, which leads to other, more profound questions. Along the way, we become familiar with concepts from such fields as topology and probability, and learn how they have led to applications such as codes and radar, computing, and even baseball statistics. Recreational and instructive, this book will appeal to die-hard math enthusiasts (of which there are many) as well as those "right-brainers" who are looking for a way to understand and enjoy math.

**How to Think Like Leonardo de Vinci: Seven Steps to Genius Every Day**

by Michael J.Gelb

Here's a personal growth guidebook that's won the admiration and recommendation of Ted Hughes, Poet Laureate of England. He calls this "a brilliant, practical guide to awakening and training our vast, unused resources of intelligence and ability." Author Michael Gelb, founder of High Performance Learning and consultant for companies including AT – and National Public Radio, says that we all can unlock the "da Vincian" genius inside us. Gelb says there are seven critical principles that need to be followed for success, whether you're learning a new language, studying to be a gourmet chef, or just hoping to be more effective on the job:

**Curiosita:** An insatiably curious approach to life. Dimonstratzione: A commitment to test knowledge through experience.

**Sensazione:** The continual refinement of the senses, especially sight, in order to clarify experience

**Sfumato**: A willingness to embrace ambiguity, paradox, and uncertainty. Arte/Scienza:The development of the balance between science and art, logic and imagination ("whole-brain thinking").

**Corporalita:** The cultivation of ambidexterity, fitness, and poise.

**Connessione:** A recognition and appreciation for the connectedness of all things and phenomena; "systems thinking."

Gelb discusses each of these principles in relation to what da Vinci accomplished, thereby giving this book a built-in history lesson. The illustrations from the master's work add a nice warmth to the work. As the president of NPR said after working with Gelb, this is a program recommended for "anyone who wants to experience a personal and professional Renaissance."

**Moment of Proof: Mathematical Epiphanies**

by Donald Benson

This is not an introduction to mathematics so much as an introduction to the pleasures of mathematical thinking. Benson covers classic problems like the sliding-tile and birthday-matching puzzles, but also delves into abstractions: counting, sorting, and "interesting numbers". This is fascinating enough, but his explanations of Russian peasant math and the secrets of the abacus have just the right mix of concreteness and abstraction to please anyone but the terminally mathphobic. Benson does expect quite a bit from his readers; paper and pencil are essential for complete understanding. But with each new epiphany, each new glimpse into the workings of the world, the effort invested in The Moment of Proof is returned, with interest.

**Search for Superstrings, Symmetry, and the Theory of Everything**

by John Gribbin

In days of yore, educated men and women would avidly follow new developments in the world of science. These days it seems to be too much trouble. Relativity was bad enough, but "N-dimensional space"? Fortunately for those of us who have trouble visualizing parallel parking, much less quarks and gluons, John Gribbin is back with an up-to-date primer on subatomic physics. Gribbin has a way of giving the reader an insight into what can only be properly understood mathematically. This book was written for those who don't know the math, but wish they did. The only thing "cheap" about this book is the price. Excellent!
