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 amazing, 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. For example, the Gilbreath Principle--a fantastic effect where the cards remain in control despite being shuffled--is found to share an intimate connection with the Mandelbrot set. Other card tricks link to the mathematical secrets of combinatorics, graph theory, number theory, topology, the Riemann hypothesis, and even Fermat's last theorem.

Diaconis and Graham are mathematicians as well as skilled performers with decades of professional experience between them. In this book they share a wealth of conjuring lore, including some closely guarded secrets of legendary magicians. "Magical Mathematics" covers the mathematics of juggling and shows how the "I Ching" connects to the history of probability and magic tricks both old and new. It tells the stories--and reveals the best tricks--of the eccentric and brilliant inventors of mathematical magic. "Magical Mathematics" 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 thirteenth century and the oldest mathematical trick--and much more.

Sir William Van Horne (1843-1915), a gifted connoisseur most famously associated with the building of the Canadian Pacific Railway, amassed of one of the most extensive collections of Japanese ceramics in North America. Obsession is an illuminating account of the how and why behind his passion for studying and acquiring nearly 1,200 objects. Ron Graham assembles a profile of Van Horne's larger-than-life personality as well as essays about his place at the top of the art collectors in Montreal's Golden Square Mile and the afterlife of his collection following his death. Accompanying the texts are historical photographs and documents, a detailed catalogue of over three hundred individual pieces in the Royal Ontario Museum and the Montreal Museum of Fine Arts, and a selection of beautiful reproductions of Van Horne's personal notebooks and exquisite watercolours from the archives of the Art Gallery of Ontario. Published in conjunction with a major exhibition at the Gardiner Museum in Toronto and the Montreal Museum of Fine Arts, Obsession presents a remarkable collection in the context of the life and career of a nineteenth-century Canadian business giant.

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, computerized systems and above all - keeping abreast of modern techniques. 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), and camera platforms (fixed wing and helicopter). A fresh approach to the subject includes: soft-copy photogrammetry using desktop 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. The book should be useful to survey operators, aerial photographers, photogrammetrists, surveyors, cartographers and mapping scientists, GIS specialists and the new generation of "desk-top" mapmakers. It is a standard reference for survey practitioners, civil engineers and planner, flight crews, and academics and students in surveying, photogrammetry, remote sensing, GIS and earth sciences.

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." Ralph Kilmann (Thomas Kilmann Conflict Indicator) *This book is part of a community wellness system created by Kelly Karius and Dr. Ron Graham, which includes this book for parents, lesson plans and strategies for schools, full community training (Community Immersions) and a website that supports schools, parents and community, an anonymous reporting system through TIPS Awareity and a safety app promoted by aBeanstalk.

In every sufficiently large structure which has been partitioned there will always be some well-behaved structure in one of the parts. This takes many forms. For example, colorings of the integers by finitely many colors must have long monochromatic arithmetic progressions (van der Waerden's theorem); and colorings of the edges of large graphs must have monochromatic subgraphs of a specified type (Ramsey's theorem). This book explores many of the basic results and variations of this theory. Since the first edition of this book there have been many advances in this field. In the second edition the authors update the exposition to reflect the current state of the art. They also include many pointers to modern results.

Sir William Van Horne (1843-1915), connaisseur bourre de talent dont la renommee est surtout attribuable a sa contribution a la construction du Chemin de fer Canadien Pacifique, a assemble l'une des collections les plus completes de ceramiques japonaises en Amerique du Nord. Obsession est un recit lumineux expliquant l'origine et l'evolution de sa passion envers l'etude et l'acquisition de pres de 1 200 objets. Ron Graham dresse le profil du personnage plus grand que nature que fut Van Horne en plus de rassembler des essais sur la place qu'il a occupee au sommet des collectionneurs d'art dans le Mille carre dore, ou Golden Square Mile, de Montreal et la perennite de sa collection apres sa mort. En exergue des textes, le lecteur pourra decouvrir des documents et des photographies historiques, un catalogue detaille de plus de trois cents objets exposes au Musee royal de l'Ontario et au Musee des beaux-arts de Montreal, de meme qu'une selection de splendides reproductions des carnets de notes personnels de Van Horne et des aquarelles raffinees provenant des archives du Musee des beaux-arts de l'Ontario. Publie parallelement a la tenue d'une importante exposition au musee Gardiner de Toronto et au Musee des beaux-arts de Montreal, Obsession presente une remarquable collection replacee dans le contexte de l'existence et de la carriere d'un geant du secteur canadien des affaires au dix-neuvieme siecle.

Over recent years, there have been numerous improvements and developments in the technology of imaging, including changes in resolution, quality of imaging and the diversity of cameras. With the increase in diversity of cameras has come a reduction in price, but the user needs to be aware of the capability of a particular camera when being sought for a specific use. More than ever, The Digital Image is an important book to guide readers through the terminology, developments and applications which together provide an overview that will inform users of imaging technology.
This new edition will therefore be the definitive handbook for digital imaging, enabling the reader to understand the technology, terms, relationships and to follow developments in this rapidly growing sector of imaging. Digital imagery offers much more than film by way of its versatility, manipulability and convenience of use, all of which are exemplified in this book. As such the book will be relevant for anyone using images and digital cameras, but especially in the commercial sectors of imaging, publishing, mapping and remote sensing and many related areas. It also forms an accessible guide to students and staff in colleges and universities, particularly in the disciplines of information technology, photography, media studies, art, electronics, physics and any subject that uses images as a data source.
