A startling book that reshapes the debate about global warming and offers a moderate approach to meeting its challenges. Bjorn Lomborg argues that many of the elaborate and expensive actions now being considered—the Kyoto Protocol, for example—have a staggering potential cost of hundreds of billions of dollars, but, ultimately, will have little impact on the world's temperature. more...

The rebellious son of a long line of pureblood cartographers and diviners, Valen has spent years trying to escape the life ordained for him. His own mother predicted how he would meet his doom-and her divination is nearly fulfilled when he winds up half-dead, addicted to an enchantment that converts pain to pleasure and possessing only a stolen book of maps. Offered sanctuary in a nearby monastery, Valen discovers that his book-rumored to lead men into the realm of angels-gains him entry into a world of secret societies, doomsayers, monks, princes, and madmen, all seeking the key to the doom of the world. Now, to preserve the lands of Navronne, Valen must face what he fled so long ago. For he alone can unlock the mystery that can save the world. more...

When Archimedes, while bathing, suddenly hit upon the principle of buoyancy, he ran wildly through the streets of Syracuse, stark naked, crying "eureka!" In The Moment of Proof, Donald Benson attempts to convey to general readers the feeling of eureka--the joy of discovery--that mathematicians feel when they first encounter an elegant proof. This is not an introduction to mathematics so much as an introduction to the pleasures of mathematical thinking. And indeed the delights of this book are many and varied. The book is packed with intriguing conundrums--Loyd's Fifteen Puzzle, the Petersburg Paradox, the Chaos Game, the Monty Hall Problem, the Prisoners' Dilemma--as well as many mathematical curiosities. We learn how to perform the arithmetical proof called "casting out nines" and are introduced to Russian peasant multiplication, a bizarre way to multiply numbers that actually works. The book shows us how to calculate the number of ways a chef can combine ten or fewer spices to flavor his soup (1,024) and how many people we would have to gather in a room to have a 50-50 chance of two having the same birthday (23 people). But most important, Benson takes us step by step through these many mathematical wonders, so that we arrive at the solution much the way a working scientist would--and with much the same feeling of surprise. Every fan of mathematical puzzles will be enthralled by The Moment of Proof. Indeed, anyone interested in mathematics or in scientific discovery in general will want to own this book. more...
