Book excerpt: New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

Book excerpt: New York Times bestselling author Kay Hooper brings together romance and suspense in this classic love story of a woman who must lie to keep a safe distance from the man she loves—because telling him the truth is too dangerous for them both. From the moment Raven Anderson literally knocks Josh Long off his feet, he’s determined to keep this elusive beauty in his tight embrace. While Raven denies their electrifying attraction and fends off his advances, Josh uses the resources of his business empire to crack the mystery surrounding Raven’s true identity. But Josh can’t bring himself to believe what the background check confirms—that Raven is an international criminal wanted for her connections to worldwide terrorism. Raven has discouraged Josh’s help and his love, but she’s going to need both. For she is playing a part in a deadly game against an adversary who never loses, who takes no prisoners, and who threatens her very life.

Download or read book The Bird Is on the Wing written by James R. Hansen and published by Texas A&M University Press. This book was released on 2004 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The airplane ranks as one of history's most ingenious and phenomenal inventions--and surely one of the most world-shaking. How ideas about its aerodynamics first came together and how the science and technology evolved to forge the airplane into the revolutionary machine it became is the epic story James R. Hansen tells in The Bird Is on the Wing. Just as the airplane is a defining technology of the twentieth century, aerodynamics has been the defining element of the airplane. Hansen provides an engaging, easily understandable introduction to the role of aerodynamics in the design of such historic American aircraft as the DC-3, X-1, and 747. Recognizing the impact individuals have had on the development of the field, he conveys not only a history of aircraft technology, but also a collective biography of the scientists, engineers, and designers who created the airplanes. From da Vinci, whose understanding of what it took to fly was three centuries too early for practical use, to the invention of the airplane by the Wright brothers, Hansen explores the technological matrix from which aeronautical engineering emerged. He skillfully guides the reader through the development of such critical aerodynamic concepts as streamlining, flutter, laminar-flow airfoils, the mythical "sound barrier," variable-sweep wing, supersonic cruise, blended body, and much more. Hansen's explanation of how vocabulary and specifications were developed to fill the gap between the perceptions of pilots and the system of engineers will fascinate all those interested in how human beings have used aerodynamics to move among, and even beyond, birds on the wing.
