Reflecting the increasing demand for efficient conversion and control of electrical power, it considers the latest power devices, circuits, and control schemes that continue to extend power electronics technology to new applications areas. Presents material methodically - first establishing the background theory before going on to specific applications. Familiarizes readers with the analysis and operation of various power conversions circuits that have applications at high power levels, and formulates equations that govern the behavior of these circuits. Discusses the application of power electronic devices in uncontrolled and controlled single phase rectifiers, inverters, ac voltage controllers, cycloconverters, and dc choppers, and demonstrates voltage and current waveform analysis for the output, starting with a simple resistive load to more practical inductive loads. Includes many worked examples, basic formulas, and an abundance of illustrations and diagrams.

    Generous support from a number of foundations provided the means for assembling and maintaining an experienced staff to co-operate with members of the Institute's Physics Department in the examination, improvement, and development of physics curriculum materials for students planning careers in the sciences. After careful analysis of objectives and the problems involved, preliminary versions of textbooks were prepared, tested through classroom use at M.I.T. and other institutions, re-evaluated, rewritten, and tried again. Only then were the final manuscripts undertaken.

    The nineteenth century saw the creation of some of the world's most incredible feats of engineering. Deborah Cadbury explores the history behind the epic monuments that spanned the industrial revolution from Brunel's extraordinary Great Eastern, the Titanic of its day that joined the two ends of the empire, to the Panama Canal, that linked the Atlantic and Pacific oceans half a century later.Seven Wonders of the Industrial World recreates the stories of the most brilliant pioneers of the industrial age, their burning ambitions and extravagant dreams, their passions and rivalries as great minds clashed. These were men such as Arthur Powell-Davis, the engineer behind the Hoover Dam, who dreamed of creating the largest dam in the world by diverting the entire Colorado river, one of the worlds most dangerous and unpredictable, or John Roebling, who lost his life creating the Brooklyn Bridge, the longest suspension bridge ever built. These are also the stories of countless unsung heroes – the craftsmen and workers without whose perseverance nothing would have been achieved, not to mention the financiers and shareholders hanging on for the ride as fortunes – and reputations – were lost and won.Cadbury leads us on an amazing journey from the freezing snows of the Alps to the mosquito-ridden wilds of the Central American jungle as we see uncontrollable rivers tamed, continents conquered and vast oceans joined.

    

    Probably no one felt more disappointment and regret than Allan McDonald, who had warned us not to launch that day. His story tells of loss, grief, and the eventual rebuilding and recovery."--Robert "Hoot" Gibson, former Space Shuttle pilot and commander   "A major contribution to a difficult episode in the history of human spaceflight."--Roger D. Launius, Division of Space History, Smithsonian Institution   “McDonald tells the heartbreaking tale of how he saw his words of warning ignored, and the fateful consequences of that decision.”--Donald C. Elder III, Eastern New Mexico University   On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals, including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation’s collective memory.   In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.  As he fought to draw attention to the real reasons behind the disaster, he was the only one targeted for retribution by both NASA and his employer, Morton Thiokol, Inc., makers of the shuttle’s solid rocket boosters. In this whistle-blowing yet rigorous and fair-minded book, McDonald, with the assistance of internationally distinguished aerospace historian James R. Hansen, addresses all of the factors that led to the accident, some of which were never included in NASA’s Failure Team report submitted to the Presidential Commission.  Truth, Lies, and O-Rings is the first look at the Challenger tragedy and its aftermath from someone who was on the inside, recognized the potential disaster, and tried to prevent it. It also addresses the early warnings of very severe debris issues from the first two post-Challenger flights, which ultimately resulted in the loss of Columbia some fifteen years later.

    Weightman weaves together the dramatic stories of giants such as Edison, Watt, Wedgwood, and Daimler, with lesser-known or entirely forgotten characters, including a group of Japanese samurai who risked their lives to learn the secrets of the West, and John “Iron Mad” Wilkinson, who didn’t let war between England and France stop him from plumbing Paris. Distilling complex technical achievements, outlandish figures, and daring adventures into an accessible narrative that spans the globe as industrialism spreads, The Industrial Revolutionaries is a remarkable work of original, engaging history.

    The consequences of this gathering may be enormous. In this new ebook, experts Patrick J. Michaels and Paul C. Knappenberger assess the issues sure to drive the debate before, during, and after the Paris meeting.

    The speeds and feeds section has been revised, updated and expanded to include new materials, more cutting tools, and tool life estimates. The welding section has been rewritten to incorporate recent developments, the numerical control section has been expanded and rearranged to facilitate use, and logarithm and trigonometry tables have been reinstated. New to this edition are sections on bolt tightening torques, motion control sections, ISO 9000, lasers, dividing heads, bandsaws (including speeds and feeds), electrical discharge machining, retaining rings, machinability of wood, and collets. In addition, all the practical information and data has been reviewed and updated where necessary.

    This edition, which was prepared by Kip S. Thorne (Feynman Professor of Theoretical Physics at California Institute of Technology), fully incorporates all the errata and corrections gathered (but never used in a published edition) by Feynman.

    Two scientists, Peter Higgs and François Englert, whose theories predicted its existence, shared a Nobel Prize. The discovery was the culmination of the largest experiment ever run, the ATLAS and CMS experiments at CERN's Large Hadron Collider.But what really is a Higgs boson and what does it do? How was it found? And how has its discovery changed our understanding of the fundamental laws of nature? And what did it feel like to be part of it?Jon Butterworth is one of the leading physicists at CERN and this book is the first popular inside account of the hunt for the Higgs. It is a story of incredible scientific collaboration, inspiring technological innovation and ground-breaking science. It is also the story of what happens when the world's most expensive experiment blows up, of neutrinos that may or may not travel faster than light, and the reality of life in an underground bunker in Switzerland.This book will also leave you with a working knowledge of the new physics and what the discovery of the Higgs particle means for how we define the laws of nature. It will take you to the cutting edge of modern scientific thinking.

    The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.
