This discovery dramatically reshaped how humans understood their place in the cosmos, and once and for all laid to rest the idea that the Milky Way galaxy was alone in the universe. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The fascinating story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit. It is a story of science in the making that shows how these discoveries were not the work of a lone genius but the combined efforts of many talented scientists and researchers toiling away behind the scenes. The intriguing characters include Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion . . . Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe . . . Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions . . . and Harlow Shapley, Hubble’s nemesis, whose flawed vision of the universe delayed the discovery of its true nature and startling size for more than a decade.Here is a watershed moment in the history of astronomy, brought about by the exceptional combination of human curiosity, intelligence, and enterprise, and vividly told by acclaimed science writer Marcia Bartusiak.

    

    It supports secure remote logins, secure file transfer between computers, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications.

So throw away those insecure .rhosts and hosts.equiv files, move up to SSH, and make your network a safe place to live and work.

    The bestselling textbook inorganic chemistry text on the market covers both theoretical and descriptive aspects of the subject, and emphasizes experimental methods, industrial applications, and modern topics.

    The latest scientific discoveries about fat metabolism and exercise are made accessible for daily use.

    In these pages both everyday riders and pros tell their stories of freak accidents, animal attacks, sabotage, idiotic decisions, eerie or unexplained incidents, and other jaw dropping, adrenalin-pumping calamities. These stories bring to life the strange things possibilities that await, once we step on the pedals of our road, mountain, or commuter bikes. A sampling of misadventures in this collection includes the stories of: the mountain biker who follows a bull and then gets gored by it; the twenty African Americans who pioneered cycle touring by completing a Transamerica ride in 1897, but wait - this story gets strange...; the large rat that leapt on top of a woman's bike and slapped her repeatedly with its tail; an inside-the-head narration by a professional racer as he rides a brutal race, and then gets humiliated in changing room afterwards; the recreational cyclist who accidentally rides deep into a prison yard; the computer programmer who crashes a stationary bike during his first spin class; the bike messenger who can't call it quits even after getting hit by eight cars; and, the man who carefully spreads out tacks on the route of an all female race in an attempt to get a date. These stories will make you wonder, drop you to the floor laughing and leave you shaking your head with disbelief.

    (The also-rans that year included Tom Wolfe, Verlyn Klinkenborg, and Oliver Sacks.) Hayes's work in this genre has also appeared in such anthologies as The Best American Magazine Writing, The Best American Science and Nature Writing, and The Norton Reader. Here he offers us a selection of his most memorable and accessible pieces--including "Clock of Ages"--embellishing them with an overall, scene-setting preface, reconfigured illustrations, and a refreshingly self-critical "Afterthoughts" section appended to each essay.

    Life Is a Wheel is the witty, inspiring, and reflective diary of his journey, in which the challenges and rewards of self-reliance and strenuous physical effort yield wry and incisive observations about cycling and America, not to mention the pleasures of a three-thousand-calorie breakfast.The story begins on the Oregon coast, with Weber wondering what he's gotten himself into, and ends in triumph on New York City's George Washington Bridge. From Going-to-the-Sun Road in the northern Rockies to the headwaters of the Mississippi and through the cityscapes of Chicago and Pittsburgh, his encounters with people and places provide us with an intimate, two-wheeled perspective of America. And with thousands of miles to travel, Weber considers his past, his family, and the echo that a well-lived life leaves behind.Part travelogue, part memoir, part romance, part paean to the bicycle; and part bemused and panicky account of a middle-aged man's attempt to stave off, well, you know;Life Is a Wheel is a book for cyclists, and for anyone who has ever dreamed of such transcontinental travels. But it also should prove enlightening, soul-stirring, even, to those who don't care a whit about bikes but who care about the way people connect (The Philadelphia Inquirer).

    This text uses place names to describe some of these meanings.

    He recounts his own experiences as an enthralled lifelong amateur astronomer and reports from around the globe -- from England and Italy to the Florida Keys and the Chilean Andes -- on the revolution that's putting millions in touch with the night sky. In addition, Ferris offers an authoritative and engaging report on what's out there to be seen -- what Saturn, the Ring nebula, the Silver Coin galaxy, and the Virgo supercluster really are and how to find them. The appendix includes star charts, observing lists, and a guide on how to get involved in astronomy. Ferris takes us inside a major revolution sweeping astronomy, as lone amateur astronomers, in global networks linked by the Internet, make important discoveries that are the envy of the professionals. His ability to describe the wonders of the universe is simply magical, and his enthusiasm for his subject is irresistible.

    Socialist doctrine had it that the two of them were `class enemies', and as a famous athlete Dieter's every move was pored over by the Stasi. Only he abhorred their ideology, and in Sylvia saw his only chance of freedom. Now, playing a deadly game of cat and mouse, he plotted his escape.In 1964 he was delegated, once and once only, to West Germany. Here he was to ride a qualification race for the Tokyo Olympics, but instead committed the most treacherous of all the crimes against socialism. Dieter Wiedemann, sporting icon and Soviet pawn, defected to the other side.Whilst Wiedemann fulfilled his lifetime ambition of racing in the Tour de France, his defection caused a huge scandal. The Stasi sought to `repatriate' him, with horrific consequences both for him and the family he left behind. Fifty years on, and twenty-five years after the fall of the Berlin Wall, Dieter Wiedemann decided it was time to tell his story. Through his testimony and that of others involved, and through the Stasi file, which has stalked him for half a century, Herbie Sykes uncovers an astonishing tale. It is one of love and betrayal, of the madness at the heart of the cold war, and of the greatest bike race in history.

    Over five decades, Star Trek's celebration of mankind's technical achievements and positive view of the future have earned it an enduring place in our global culture. Its scientific vision has also had a profound effect on the past thirty years of technological breakthroughs. Join William Shatner, the original captain of the Starship Enterprise, as he reveals how Star Trek has influenced and inspired some of our greatest scientific minds -- the people behind the future we will all share. In interviews with dozens of scientists we learn about the inventions that will revolutionise our lives and the discoveries that will make it truly possible to explore the last great frontier -- space. As one Nobel Laureate commented on being shown a wood and plastic model of the engine core from a Star Trek: The Next Generation starship: I'm working on that. From the technicalities of warp speed to real-life replicators to the likelihood of our being able to beam across continents, this always-informative book takes us on a fascinating and eye-opening voyage to
