On August 8, 1900, at the second International Congress of Mathematicians in Paris, David Hilbert delivered his famous lecture in which he described twenty-three problems that were to play an influential role in mathematical research. A century later, on May 24, 2000, at a meeting at the Collège de France, the Clay Mathematics Institute (CMI) announced the creation of a US$7 million prize fund for the solution of seven important classic problems which have resisted solution. The prize fund is divided equally among the seven problems. There is no time limit for their solution. The Millennium Prize Problems were selected by the founding Scientific Advisory Board of CMI—Alain Connes, Arthur Jaffe, Andrew Wiles, and Edward Witten—after consulting with other leading mathematicians. Their aim was somewhat different than that of Hilbert: not to define new challenges, but to record some of the most difficult issues with which mathematicians were struggling at the turn of the second millennium; to recognize achievement in mathematics of historical dimension; to elevate in the consciousness of the general public the fact that in mathematics, the frontier is still open and abounds in important unsolved problems; and to emphasize the importance of working towards a solution of the deepest, most difficult problems. The present volume sets forth the official description of each of the seven problems and the rules governing the prizes. It also contains an essay by Jeremy Gray on the history of prize problems in mathematics.

Being able to talk to ponies isn't all that it's cracked up to be! Pia never thought anyone actually one magazine contests. So when her friend Beans wins a riding vacation for two, she's totally excited to go with her. A whole wonderful week riding new ponies and making fabulous new friends. But when things start to go missing around the ranch, Pia turns to the ponies to see what they have to say--and is shocked at what she hears! Can Pia and her new pony pals solve the mystery before their vacation gallops to an end? "This combination of magic and quick-moving, contemporary plot is a light and enjoyable read. The horses are particularly amusing as they reveal their complaints and requests to their owners through Pia."--School Library Journalreview for The Pony Whisperer: The Word on the Yard

In 2000, the Clay Foundation of Cambridge, Massachusetts, announced a historic competition: Whoever could solve any of seven extraordinarily difficult mathematical problems, and have the solution acknowledged as correct by the experts, would receive $1million in prize money. They encompass many of the most fascinating areas of pure and applied mathematics, from topology and number theory to particle physics, cryptography, computing and even aircraft design. Keith Devlin describes here what the seven problems are, how they came about, and what they mean for mathematics and science. In the hands of Devlin, each Millennium Problem becomes a fascinating window onto the deepest questions in the field.

Henri Poincaré was one of the greatest mathematicians of the late nineteenth and early twentieth century. He revolutionized the field of topology, which studies properties of geometric configurations that are unchanged by stretching or twisting. The Poincaré conjecture lies at the heart of modern geometry and topology, and even pertains to the possible shape of the universe. The conjecture states that there is only one shape possible for a finite universe in which every loop can be contracted to a single point. Poincaré's conjecture is one of the seven "millennium problems" that bring a one-million-dollar award for a solution. Grigory Perelman, a Russian mathematician, has offered a proof that is likely to win the Fields Medal, the mathematical equivalent of a Nobel prize, in August 2006. He also will almost certainly share a Clay Institute millennium award. In telling the vibrant story of The Poincaré Conjecture, Donal O'Shea makes accessible to general readers for the first time the meaning of the conjecture, and brings alive the field of mathematics and the achievements of generations of mathematicians whose work have led to Perelman's proof of this famous conjecture.

From former UN Ambassador and author of the New York Times bestseller The Education of an Idealist Samantha Power, the Pulitzer Prize-winning book on America's repeated failure to stop genocides around the world In her prizewinning examination of the last century of American history, Samantha Power asks the haunting question: Why do American leaders who vow "never again" repeatedly fail to stop genocide? Power, a professor at the Harvard Kennedy School and the former US Ambassador to the United Nations, draws upon exclusive interviews with Washington's top policymakers, thousands of declassified documents, and her own reporting from modern killing fields to provide the answer. "A Problem from Hell" shows how decent Americans inside and outside government refused to get involved despite chilling warnings, and tells the stories of the courageous Americans who risked their careers and lives in an effort to get the United States to act. A modern classic and "an angry, brilliant, fiercely useful, absolutely essential book" (New Republic), "A Problem from Hell" has forever reshaped debates about American foreign policy.
