Download or read book Unknown Quantity written by John Derbyshire and published by National Academies Press. This book was released on 2006-06-02 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book We Are Doomed written by John Derbyshire and published by Forum Books. This book was released on 2009-09-29 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Old Roads of Derbyshire written by Stephen Bailey and published by Troubador Publishing Ltd. This book was released on 2019-04-16 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derbyshire has a wealth of old roads, lanes, tracks, hollow ways and paths, some dating back thousands of years. It is a network which links a fascinating variety of sometimes enigmatic monuments, from fortified hilltops and stone circles to ruined abbeys and hermitages, ancient churches and tumuli. The Old Roads of Derbyshire traces the development of these roads, from prehistoric ridgeways, Roman ‘streets’ and medieval pilgrimage routes to the growth of the turnpikes, and finally to leisure use by cyclists and hikers. Travellers of all kinds are included: ‘jaggers’ with their packhorse trains, pilgrims, drovers, pedlars and tramps, and passengers in stage coaches and wagons, as well as the essential infrastructure of bridges and inns. The Derbyshire Portway is explored as an example of an ancient route which was old before the Romans arrived, but was used well into the eighteenth century, and one that can still be followed today. A detailed walking guide, fully illustrated with maps and photos, is provided for the sixty-plus miles of its route, from the River Trent, near Nottingham, to deep into the Dark Peak.
