    It has a reputation as a dry and difficult subject, a glorified form of geometry complicated by tedious computation. In this book, Eli Maor draws on his remarkable talents as a guide to the world of numbers to dispel that view. Rejecting the usual arid descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. He presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social development. Woven together in a tapestry of entertaining stories, scientific curiosities, and educational insights, the book more than lives up to the title Trigonometric Delights.Maor, whose previous books have demystified the concept of infinity and the unusual number "e," begins by examining the "proto-trigonometry" of the Egyptian pyramid builders. He shows how Greek astronomers developed the first true trigonometry. He traces the slow emergence of modern, analytical trigonometry, recounting its colorful origins in Renaissance Europe's quest for more accurate artillery, more precise clocks, and more pleasing musical instruments. Along the way, we see trigonometry at work in, for example, the struggle of the famous mapmaker Gerardus Mercator to represent the curved earth on a flat sheet of paper; we see how M. C. Escher used geometric progressions in his art; and we learn how the toy Spirograph uses epicycles and hypocycles.Maor also sketches the lives of some of the intriguing figures who have shaped four thousand years of trigonometric history. We meet, for instance, the Renaissance scholar Regiomontanus, who is rumored to have been poisoned for insulting a colleague, and Maria Agnesi, an eighteenth-century Italian genius who gave up mathematics to work with the poor--but not before she investigated a special curve that, due to mistranslation, bears the unfortunate name "the witch of Agnesi." The book is richly illustrated, including rare prints from the author's own collection. Trigonometric Delights will change forever our view of a once dreaded subject.

    Constable Wood was a disaster waiting to happen. He was the sort of cop who was happier helping little old ladies across the street (even when they were quite content where they were) than pursuing the perpetrators of dreadful deeds. But if he failed to strike fear into the hearts of the criminal underworld, his superiors had a real problem on their hands. Never before had they been forced to deal with such a well-meaning but accident-prone officer and they hoped, fervently, never to see his like again. From his early encounters with a less-than-impressed public, through the terrifying days of the Springbok Tour riots, to the gradual realisation that perhaps he wasn’t cut out for life on the beat, this is the hilarious story of a young cop who created a severe disturbance in the force.

    The stunning images are explained with clear and detailed text. The full color book illustrates and explains the nature of every category of celestial object in a clear and concise manner.

    

    

    Almost five hundred years later, the revolution he set in motion is nearly complete. Just as earth is not the center of things, the life on it, it appears, is not unique to the planet. Or is it? The Life of Super-Earths is a breathtaking tour of current efforts to answer the age-old question: Are we alone in the universe? Astronomer Dimitar Sasselov, the founding director of Harvard University’s Origins of Life Initiative, takes us on a fast-paced hunt for habitable planets and alien life forms. He shows how the search for “super-Earths”—rocky planets like our own that orbit other stars—may provide the key to answering essential questions about the origins of life here and elsewhere. That is, if we don’t find the answers to those questions here first. As Sasselov and other astronomers have uncovered planets with mixes of elements different from our own, chemists have begun working out the heretofore unseen biochemistries that those planets could support. That knowledge is feeding directly into synthetic biology—the effort to build wholly novel forms of life—making it likely that we will first discover truly “alien” life forms in an earthly lab, rather than on a remote planet thousands of light years away. Sasselov tells the gripping story of a moment of unprecedented potential—a convergence of pioneering efforts in astronomy and biology to peer into the unknown. The Life of Super-Earths offers nothing short of a transformation in our understanding of life and its place in the cosmos.

    The twelfth edition of "Earth Science "offers a user-friendly overview of our physical environment with balanced, up-to-date coverage of geology, oceanography, astronomy, and meteorology for the undergraduate student with little background in science. The emphasis is on readability, with clear example-driven explanations. The twelfth edition takes full advantage of the subject's visual appeal, with discussions reinforced by incredible color photos and superb illustrations by Earth science illustrator and geologist Dennis Tasa.

    With an updated preface for this new edition, EINSTEIN explains how the scientific icon changed our view of the world and why no one can ever hope to understand it without first understanding his work.

    This fascinating dictionary explores the development of meaning, spelling, and pronunciation of over 25,000 English words. Over 30,000 detailed entries trace words back to their Proto-Germanic or Indo-European roots, and include words borrowed from other languages, as well as the sources and dates of their first recorded use. For many years academics, wordsmiths, crossword lovers, and language enthusiasts of all stripes have turned to this celebrated volume as their reference of choice in lexical matters. First published as the Barnhart Etymological Dictionary, the Chambers Dictionary of Etymology offers a unique combination of approachability and authoritativeness in an accessible single-volume format, making it an essential etymological resource for the expert, and a fascinating reference for the general reader. Sample entry from the Chambers Etymological Dictionary: blarney n. flattering, coaxing talk. 1766, Lady Blarny (for Blarney), a smooth-talking flatterer in Goldsmith's the Vicar of Wakefield, her name being a literary contrivance in allusion to Blarney Stone, a stone in a castle near Cork, Ireland. Anyone kissing the stone is supposed to become skillful in flattering and coaxing. The word is used in its general sense in a letter of Sir Walter Scott (1796).

    But when two faces from his old gang turn up, he finds himself getting involved in a new scam, and soon he is embroiled in a world he wants to escape and is forced to confront a man who is dangerously unhinged.

    Not an easy job, given the lingering resonance of Serbia's role in the 1990s Yugoslav wars in the world’s news bulletins. To this day, the words "Serbia" and "atrocities" are linked in the minds of many. This study of both Djokovic and Serbia paints two powerful portraits. It traces the story of the boy from modest surroundings, telling how he met the woman who not only taught him tennis but how to deal with life as a high-profile icon, charts his battle with illness and his relationship with a volatile father, and how his on-court accomplishments have made his country proud. But it also tells the story of Serbia, pulling no punches about its role in the 1990s wars but offering a sensitive interpretation of the hopes and aspirations of a people with a troubled past. This book weaves together these sporting and geo political strands to present a sensitive portrait of a man and his people, and how determination married with sensitivity can create a sporting statesman.

    From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos.Sagan himself said of Zubrin's humans-to-Mars plan, "Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space, he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

    He tells his life story, from growing up in the Midlands to all the excesses of glam rock, and is currently busy carving out a new career for himself in the TV sitcom, The Grimleys.
