In one last attempt to renew the constitution with the consent of the provinces, Prime Minister Pierre Elliott Trudeau met behind closed doors in Ottawa with the ten premiers. It was the culmination of more than five decades of constitutional wrangling, and has been called the most important conference since the Fathers of Confederation got together in Quebec City in 1864. Faced with the threat of Quebec independence, the ambitions of Western Canada, and the provinces’ demands for more power, Trudeau was embattled. But he was fiercely determined to make Canadians fully independent and to entrench a Charter of Rights and Freedoms.

What happened that day still reverberates. It severed the last important link to Canada’s colonial past. It guaranteed individual liberty and minority rights in the future. It weakened the grip of the elites and gave ownership of the constitution to Canadians. But it came at a price.

Quebec alone refused to sign the final deal. René Lévesque, its separatist premier, claimed he had been betrayed by his allies in the Gang of Eight. The legend of the "Night of the Long Knives" took hold, precipitating a series of events that came close to destroying the country.

Thirty years later, author Ron Graham delivers a gripping account of the fractious debates and secret negotiations. He uses newly uncovered documents and the candid recollections of many of the key participants to create a vivid record of that momentous twenty-four hours. Authoritative and engaging, The Last Act is a remarkable combination of scholarly research and historical narrative.

This book is a tribute to Paul Erdos, the wandering mathematician once described as the "prince of problem solvers and the absolute monarch of problem posers." It examines the legacy of open problems he left to the world after his death in 1996.

50 Years of Combinatorics, Graph Theory, and Computing advances research in discrete mathematics by providing current research surveys, each written by experts in their subjects.

The book also celebrates outstanding mathematics from 50 years at the Southeastern International Conference on Combinatorics, Graph Theory & Computing (SEICCGTC). The conference is noted for the dissemination and stimulation of research, while fostering collaborations among mathematical scientists at all stages of their careers.

The authors of the chapters highlight open questions. The sections of the book include: Combinatorics; Graph Theory; Combinatorial Matrix Theory; Designs, Geometry, Packing and Covering. Readers will discover the breadth and depth of the presentations at the SEICCGTC, as well as current research in combinatorics, graph theory and computer science.

The mathematics behind some of the world''s most amazing card tricksMagical 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.
