This book is a tribute to Paul Erdos, the wandering mathematician once described as the "prince of problem solvers and the absolute monarch or problem posers". It examines -- within the context of his unique personality and lifestyle -- the legacy of open problems he left to the world after his death in 1996. Unwilling to succumb to the temptations of money and position, Erdos never had a home and never held a job. His "home" was a bag or two containing all his belongings and a record of the collective activities of the mathematical community. His "job" was one at which he excelled: identifying a fundamental roadblock in some particular line of approach and capturing it in a well-chosen, often innocent-looking problem, whose solution would likewise provide insight into the underlying theory. By cataloguing the unsolved problems of Erdos in a comprehensive and well-documented volume, the authors hope to continue the work of an unusual and special man who fundamentally influenced the field of mathematics.

Magical Mathematics reveals the secrets of fun-to-perform card tricks--and the profound mathematical ideas behind them--that will astound even the most accomplished magician. Persi Diaconis and Ron Graham provide easy, step-by-step instructions for each trick, explaining how to set up the effect and offering tips on what to say and do while performing it. Each card trick introduces a new mathematical idea, and varying the tricks in turn takes readers to the very threshold of today's mathematical knowledge. Diaconis and Graham tell the stories--and reveal the best tricks--of the eccentric and brilliant inventors of mathematical magic. The book exposes old gambling secrets through the mathematics of shuffling cards, explains the classic street-gambling scam of three-card Monte, traces the history of mathematical magic back to the oldest mathematical trick--and much more.

Does your child talk about being treated badly by his peers, and you don't know what to do? Does the school tell you to make your child stop bullying, and you don't know how? You'll find concrete answers inside this book. For years and years we have talked about bullies and victims. We've talked about them enough that the words have shaped the lives of many people. It's time for a whole new framework. No more will we speak of bullies and victims. No more will we give power to the idea that bullying is inherent in our society, or that "Kids can be cruel." This new framework throws traditional bullying theory on its head, examining bully actions and victim responses, instead of labelling children. It teaches lessons that help each and every one of us, adult and child, stop ourselves from falling into either category. Use the information and lessons to learn the information yourself. Use the activities to teach the information to your children. People who communicate well and have developed a strong self-concept, balanced thinking, balanced approaches and empathy for others are less likely to use bully actions or victim responses. It's simple. All children need the same skills. Children aren't "bullies" and they don't need to be "victims." They just need to be provided opportunity to learn. All children need the same skills. "It was a pleasure to read your book and see how well you present your valuable ideas and strategies for removing the horrible effects of bullying behavior, victim behavior, and bystander behavior. Your writing is beautiful, clear, passionate, and meaningful. If all parents, children, teachers, and administrators could be exposed to your ideas and methods, we would soon have a safer childhood experience for all our loved ones."

Primary data acquisition is the front end of mapping, GIS and remote sensing and involves: aviation, navigation, photography, cameras (film and digital systems), GPS systems, surveying (ground control), photogrammetry and computerized systems.This book deals with differential GPS systems, survey flight management systems (both simple and sophisticated), film types, modern film survey cameras such as LH RC-30, Z/I RMK-TOP, digital cameras, infrared methods, laser profilers, airborne laser mapping, satellite systems, laboratory processing (chemical and digital), camera platforms (fixed wing and helicopter). A fresh approach to the subject includes: soft-copy photogrammetry using desk-top computerized systems, film scanners and direct digital camera inputs. Comparisons are made between old film-based technologies and the new digital camera systems, including the Z/I modular digital mapping camera and the LH 'push-broom' ADS 40 camera.
