It reveals the visions they shared, the sacrifices they made, and the rewards they reaped.

    But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe's first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it.Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

    This fascinating book traces what was a massive accomplishment right from the early launches through manned orbital spaceflights, detailing each step. Out of the battlefields of World War II came the gifted German engineers and designers who developed the V-2 rocket, which evolved into the powerful Saturn V booster that propelled men to the Moon. David Woods tells this exciting story, starting from America 's postwar astronautical research facilities. The techniques and procedures developed have been recognised as an example of human exploration at its greatest, demonstrating a peak of technological excellence.

    This essay by Copernicus (1473-1543), revolutionized the way we look at the earth's placement in the universe, and paved the way for many great scientists, including Galileo and Isaac Newton, whose theories stemmed from this model. Featuring a biography of Copernicus and an accessible, enlightening introduction, both written by the renowned physicist Stephen Hawking, On the Revolution of Heavenly Spheres provides a fascinating look at the theories which shaped our modern understanding of astronomy and physics.

    Brooding, iconoclastic, prophetic, Abbey was principally known as a prose writer, the author of such legendary works as The Monkey Wrench Gang, Desert Solitaire, and The Brave Cowboy.Although Abbey rarely published his poetry, he was, unbeknownst to his loyal and often fanatical public, a passionate producer of verse, and these seventy-one original poems—never before published in any form (although several were rejected by the leading magazines of the nation)—offer an insightful and wrenching look into the mind of this great man known to some as "Cactus Ed." To read these poems, all written between 1952 and 1989, and culled from his Journals, is to feel the ineffable, irrefutable essence of Edward Abbey. The poems frequently alternate between the joy and pain that marked his life, and all brandish his immutable character and nonconformity.Whether writing about his love of wild doves, his unadulterated hatred of New York City, or his fondness for bawdy women, Abbey was unapologetically passionate—and these poems will only add to his literary reputation and mythic stature.Not bad for a spud-digging farm boy out of rural Pennsylvania.

    That first trip to America’s last frontier convinced him he would one day call the state home. With heartfelt honesty and inspirational enthusiasm, Maranville here tells the story of his transition from living within the contiguous forty-eight states to homesteading north of the Arctic Circle. After serving in the US Army in Vietnam as an aircraft mechanic, he decided to file for the grant of a homesite in the Alaskan wilds. Once he’d staked the land, he faced the challenge of fulfilling the five-year land-improvement requirements prescribed by the Homestead Act. While earning his homestead, he encountered new opportunities, amazing adventures—and frightening hazards. Working as a helicopter mechanic, he soon partnered with a helicopter pilot and they began the farthest North helicopter company, Sunshine Helicopters, out of Circle City, Alaska along the Yukon River. He built his family a log cabin in the wilderness along the picturesque banks of the Ambler River, where they confronted bears, extreme cold, dangerous working conditions, and rugged landscape—and survived a devastating flood. Yet the difficulties were worth it. At last, Maranville received one of the final patents granted under the Homestead Act before the act was discontinued.

    Children are interested in things like where do certain animal come from and where does the rain come from. Children are also interested in the sky and how far away it is from the ground. Nature will also teach children how animals and insects get their food. This will force children to paint a picture of this in their mind. This picture will become real to children of all ages.

    Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang--known as the cosmic microwave background, or CMB--and how their findings are transforming our view of the cosmos.Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure.Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers--from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe.

    From the big bang to the present and into the next millenium, The Universe Story unites science and the humanities in a dramatic exploration of the unfolding of the universe, humanity's evolving place in the cosmos, and the boundless possibilities for our future.

    But the wilderness conceals more than one perilous mystery. Where in Wisconsin's Northwoods did the notorious gangster John Dillinger hide $210,000 following a violent FBI shootout? And why do the local timberwolves incite so much rage among Natalie's neighbors? As predators circle and howl in the dark, Ginger, the bartender at the nearby Star Lake Saloon, draws Natalie deep into the secrets not only of Dillinger but of the ecologies of family, forest, and heart. With the reluctant support of her granddaughter and advice from a handsome wolf biologist, Natalie is forced to choose between adversity and adventure. Sara Rath continues her popular Northwoods saga in this affirming and often humorous tale of romance, betrayal, and danger.
