This book was released on 2021-03-09 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Sierra Club's 2021 Rachel Carson Award One of Chicago Tribune's Ten Best Books of 2021 Named a Top Ten Best Science Book of 2021 by Booklist and Smithsonian Magazine "At once thoughtful and thought-provoking,” Beloved Beasts tells the story of the modern conservation movement through the lives and ideas of the people who built it, making “a crucial addition to the literature of our troubled time" (Elizabeth Kolbert, author of The Sixth Extinction). In the late nineteenth century, humans came at long last to a devastating realization: their rapidly industrializing and globalizing societies were driving scores of animal species to extinction. In Beloved Beasts, acclaimed science journalist Michelle Nijhuis traces the history of the movement to protect and conserve other forms of life. From early battles to save charismatic species such as the American bison and bald eagle to today’s global effort to defend life on a larger scale, Nijhuis’s “spirited and engaging” account documents “the changes of heart that changed history” (Dan Cryer, Boston Globe). With “urgency, passion, and wit” (Michael Berry, Christian Science Monitor), she describes the vital role of scientists and activists such as Aldo Leopold and Rachel Carson, reveals the origins of vital organizations like the Audubon Society and the World Wildlife Fund, explores current efforts to protect species such as the whooping crane and the black rhinoceros, and confronts the darker side of modern conservation, long shadowed by racism and colonialism. As the destruction of other species continues and the effects of climate change wreak havoc on our world, Beloved Beasts charts the ways conservation is becoming a movement for the protection of all species including our own.

Download or read book Mechanical Similitude and Turbulence written by Theodore Von Kármán and published by . This book was released on 1931 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the theory of the vortex street which enables the reproduction of the mechanism of the form resistance with suitable approximation under stated conditions, although such a resistance is precluded in a fluid which is perfectly inviscid. Disregarding for the present the origination of the vortex, the stream attitude in the wake of the body may be described approximately correct by the representation of individual vortices, without transgressing the law governing the motion of such vortices in an ideal fluid. Another striking example is the theory of the induced drag of wings, which likewise shows the extent of applying the vortex equations without overstepping the bounds of the dynamics of ideal fluids.

Download or read book Hawk Ridge written by Laura Erickson and published by U of Minnesota Press. This book was released on 2012 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Was Caesar like the eagle because of his aquiline (from aquila, for “eagle” in Latin) nose, or does the eagle seem imperial because of his Caesar-like beak? Does the sharp vision of a “hawk-eyed” observer have any basis in nature? And what the heck is “kettling” to a bird-watcher, or, for that matter, a bird? Raptors have captured the imagination from time immemorial and have an especially rich history in Minnesota. The ancient peoples whose pictographs adorn the rock faces of Lake Superior's North Shore may well have witnessed the first hawk movements along Lake Superior—the same annual migration that today draws as many as twenty thousand people to Duluth's Hawk Ridge. These birds, passing through in astounding numbers, are among the hawks and accipiters, buteos and harriers, eagles and ospreys pictured and profiled in detail in this book. Written by one of Minnesota's best-known bird authorities, with images by one of the state's favorite illustrators, Hawk Ridge is as fun as it is informative. It introduces the state's raptors, from the rare visitor to the most familiar hawk, noting each species' signature traits—osprey wings, for instance, are crooked to help them catch fish; vultures urinate on their legs to cool themselves—and their nesting, breeding, and migrating habits. Did you know that Sharp-shinned Hawks banded at Hawk Ridge have been found throughout Central America and even into South America, and also, in midwinter, in Wisconsin? Laura Erickson offers a broad perspective (a bird's-eye view!), making sense of the raptor's role in the larger ornithological scheme. With descriptions of various species—and helpful distinctions between species, families, and orders—the book gives readers a clear idea of which raptors might be seen in Minnesota, when, where, and how often. It also includes a hawk migration primer that explains the movements that bring these birds in such awe-inspiring numbers to places like Hawk Ridge. Filled with curious facts and practical information for expert and amateur bird-watcher alike, the book is at once a guide to the hawks of Minnesota and a beautifully illustrated album of the most regal members of the avian kingdom.
Download or read book Locomotive to Aeromotive written by Simine Short and published by University of Illinois Press. This book was released on 2011-08-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: French-born and self-trained civil engineer Octave Chanute designed America's two largest stockyards, created innovative and influential structures such as the Kansas City Bridge over the previously "unbridgeable" Missouri River, and was a passionate aviation pioneer whose collaborative approach to aeronautical engineering problems encouraged other experimenters, including the Wright brothers. Drawing on rich archival material and exclusive family sources, Locomotive to Aeromotive is the first detailed examination of Chanute's life and his immeasurable contributions to engineering and transportation, from the ground transportation revolution of the mid-nineteenth century to the early days of aviation. Aviation researcher and historian Simine Short brings to light in colorful detail many previously overlooked facets of Chanute's professional and personal life. In the late nineteenth century, few considered engineering as a profession on par with law or medicine, but Chanute devoted much time and energy to the newly established professional societies that were created to set standards and serve the needs of civil engineers. Though best known for his aviation work, he became a key figure in the opening of the American continent by laying railroad tracks and building bridges, experiences that later gave him the engineering knowledge to build the first stable aircraft structure. Chanute also introduced a procedure to treat wooden railroad ties with an antiseptic that increased the wood’s lifespan in the tracks. Establishing the first commercial plants, he convinced railroad men that it was commercially feasible to make money by spending money on treating ties to conserve natural resources. He next introduced the date nail to help track the age and longevity of railroad ties. A versatile engineer, Chanute was known as a kind and generous colleague during his career. Using correspondence and other materials not previously available to scholars and biographers, Short covers Chanute's formative years in antebellum America as well as his experiences traveling from New Orleans to New York, his apprenticeship on the Hudson River Railroad, and his early engineering successes. His multiple contributions to railway expansion, bridge building, and wood preservation established his reputation as one of the nation's most successful and distinguished civil engineers. Instead of retiring, he utilized his experiences and knowledge as a bridge builder in the development of motorless flight. Through the reflections of other engineers, scientists, and pioneers in various fields who knew him, Short characterizes Chanute as a man who believed in fostering and supporting people who were willing to learn. This well-researched biography cements Chanute's place as a preeminent engineer and mentor in the history of transportation in the United States and the development of the airplane.

Download or read book Schurman Rock written by Jeff Smoot and published by . This book was released on 2018-05-04 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part history, part biography, part climbing guide, Schurman Rock: A History & Guide describes the design and construction of Schurman Rock, the world's first artificial climbing wall, built in 1938-39 at Camp Long in Seattle, Washington. The book includes a history of the creation of Camp Long by by William G. Long, a Superior Court judge, who seized the opportunity to turn an unused 68-acre tract of swampy forest land into a wilderness camp for youth, and a biography of Clark Schurman, a Scoutmaster and Chief Climbing Guide at Mount Rainier, who envisioned and then built his "dream rock" to provide a place to teach mountaineering skills to youth. Thousands of kids and adults, including Fred Beckey and Jim and Lou Whittaker, learned to climb on Schurman Rock over the past 80 years. In 1938, Schurman published an article describing 22 routes on the rock--"short bits" as he called them. This book expands on this with a guide to several boulder problems on the rock. Includes many historic photos and a foreword by Pacific Northwest climbing legend Jim Whittaker.
Download or read book Dressing for Altitude written by Dennis R. Jenkins and published by Government Printing Office. This book was released on 2012-08-27 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Since its earliest days, flight has been about pushing the limits of technology and, in many cases, pushing the limits of human endurance. The human body can be the limiting factor in the design of aircraft and spacecraft. Humans cannot survive unaided at high altitudes. There have been a number of books written on the subject of spacesuits, but the literature on the high-altitude pressure suits is lacking. This volume provides a high-level summary of the technological development and operational use of partial- and full-pressure suits, from the earliest models to the current high altitude, full-pressure suits used for modern aviation, as well as those that were used for launch and entry on the Space Shuttle. The goal of this work is to provide a resource on the technology for suits designed to keep humans alive at the edge of space."--NTRS Web site.
