To his fellow conservatives, John Derbyshire makes a plea: Don't be seduced by this nonsense about "the politics of hope." Skepticism, pessimism, and suspicion of happy talk are the true characteristics of an authentically conservative temperament. And from Hobbes and Burke through Lord Salisbury and Calvin Coolidge, up to Pat Buchanan and Mark Steyn in our own time, these beliefs have kept the human race from blindly chasing its utopian dreams right off a cliff. Recently, though, various comforting yet fundamentally idiotic notions of political correctness and wishful thinking have taken root beyond the "Kumbaya"-singing, we're-all-one crowd. These ideas have now infected conservatives, the very people who really should know better. The Republican Party has been derailed by legions of fools and poseurs wearing smiley-face masks. Think rescuing the economy by condemning our descendents to lives of spirit-crushing debt. Think nation-building abroad while we slowly disintegrate at home. Think education and No Child Left Behind. . . . But don't think about it too much, because if you do, you'll quickly come to the logical conclusion: We are doomed. Need more convincing? Dwell on the cheerful promises of the diversity cult and the undeniable reality of the oncoming demographic disaster. Contemplate the feminization of everything, or take a good look at what passes for art these days. Witness the rise of culturism and the death of religion. Bow down before your new master, the federal apparatchik. Finally, ask yourself: How certain am I that the United States of America will survive, in any recognizable form, until, say, 2022? A scathing, mordantly funny romp through today's dismal and dismaler political and cultural scene, We Are Doomed provides a long-overdue dose of reality, revealing just how the GOP has been led astray in recent years–and showing that had conservatives held on to their fittingly pessimistic outlook, America's future would be far brighter. Ladies and gentlemen, it's time to embrace the Audacity of Hopelessness.

Prime Obsession taught us not to be afraid to put the math in a math book. Unknown Quantity heeds the lesson well. So grab your graphing calculators, slip out the slide rules, and buckle up! John Derbyshire is introducing us to algebra through the ages-and it promises to be just what his die-hard fans have been waiting for. "Here is the story of algebra." With this deceptively simple introduction, we begin our journey. Flanked by formulae, shadowed by roots and radicals, escorted by an expert who navigates unerringly on our behalf, we are guaranteed safe passage through even the most treacherous mathematical terrain. Our first encounter with algebraic arithmetic takes us back 38 centuries to the time of Abraham and Isaac, Jacob and Joseph, Ur and Haran, Sodom and Gomorrah. Moving deftly from Abel's proof to the higher levels of abstraction developed by Galois, we are eventually introduced to what algebraists have been focusing on during the last century. As we travel through the ages, it becomes apparent that the invention of algebra was more than the start of a specific discipline of mathematics-it was also the birth of a new way of thinking that clarified both basic numeric concepts as well as our perception of the world around us. Algebraists broke new ground when they discarded the simple search for solutions to equations and concentrated instead on abstract groups. This dramatic shift in thinking revolutionized mathematics. Written for those among us who are unencumbered by a fear of formulae, Unknown Quantity delivers on its promise to present a history of algebra. Astonishing in its bold presentation of the math and graced with narrative authority, our journey through the world of algebra is at once intellectually satisfying and pleasantly challenging.

In August 1859 Bernhard Riemann, a little-known 32-year old mathematician, presented a paper to the Berlin Academy titled: "On the Number of Prime Numbers Less Than a Given Quantity." In the middle of that paper, Riemann made an incidental remark â€" a guess, a hypothesis. What he tossed out to the assembled mathematicians that day has proven to be almost cruelly compelling to countless scholars in the ensuing years. Today, after 150 years of careful research and exhaustive study, the question remains. Is the hypothesis true or false? Riemann's basic inquiry, the primary topic of his paper, concerned a straightforward but nevertheless important matter of arithmetic â€" defining a precise formula to track and identify the occurrence of prime numbers. But it is that incidental remark â€" the Riemann Hypothesis â€" that is the truly astonishing legacy of his 1859 paper. Because Riemann was able to see beyond the pattern of the primes to discern traces of something mysterious and mathematically elegant shrouded in the shadows â€" subtle variations in the distribution of those prime numbers. Brilliant for its clarity, astounding for its potential consequences, the Hypothesis took on enormous importance in mathematics. Indeed, the successful solution to this puzzle would herald a revolution in prime number theory. Proving or disproving it became the greatest challenge of the age. It has become clear that the Riemann Hypothesis, whose resolution seems to hang tantalizingly just beyond our grasp, holds the key to a variety of scientific and mathematical investigations. The making and breaking of modern codes, which depend on the properties of the prime numbers, have roots in the Hypothesis. In a series of extraordinary developments during the 1970s, it emerged that even the physics of the atomic nucleus is connected in ways not yet fully understood to this strange conundrum. Hunting down the solution to the Riemann Hypothesis has become an obsession for many â€" the veritable "great white whale" of mathematical research. Yet despite determined efforts by generations of mathematicians, the Riemann Hypothesis defies resolution. Alternating passages of extraordinarily lucid mathematical exposition with chapters of elegantly composed biography and history, Prime Obsession is a fascinating and fluent account of an epic mathematical mystery that continues to challenge and excite the world. Posited a century and a half ago, the Riemann Hypothesis is an intellectual feast for the cognoscenti and the curious alike. Not just a story of numbers and calculations, Prime Obsession is the engrossing tale of a relentless hunt for an elusive proof â€" and those who have been consumed by it.

This is a magical novel of a Chinese immigrant's coming to terms with himself, his marriage, and America--and the unlikely moral force that guides his life. Chai is middle-aged, a disillusioned formed Red Guard who escaped China for Hong Kong and then America, where he works in New York as a banker. He and his wife, Ding, are the parents of an infant and enjoy a contented marriage; he develops a fond obsession with President Calvin Coolidge, the taciturn New Englander whose wry wit and wisdom delights Chai. One day, a chance discovery leads him astray: He learns that a lover from his youth is now in Boston, living with her husband and their son. The son is Chai's very image, and the staid banker is inflamed by the implications of the resemblance. Confused by his emotions, he becomes determined to revive the affair. How Ding schemes to win back her wayward husband--and teach him the necessary truths about love--forms the plot and beguiling conclusion to John Derbyshire's tale.

This book describes the psychological strategies the world class sailors use to set goals, manage stress and build confidence. Part 3 contains photo sequences of sailing-specific exercises that can be used to build an individual training programme. Set goals for confidence building and competition.
