From the ancient origins of astronomy to the Copernican revolution, and from Galileo to Hawking's research into black holes, The Story of Astronomy charts the discoveries made by some of the greatest minds in human history, and their attempts to unveil the secrets of the stars. Written in an accessible and entertaining style, The Story of Astronomy demystifies some of the biggest breakthroughs in the history of science, as well as explaining why we have 60 minutes in an hour, how the Romans bodged the invention of the leap year and when people really discovered the Earth wasn't flat (a thousand years before Columbus. In the most straightforward and compelling of ways Peter Aughton demonstrates the beauty and wonder of what Newton, Einstein, Hubble and Hawking really achieved.

The highly successful Clementine mission to the Moon in 1994 gave scientists their first global look at the Moon, and both the near and far side were mapped. This atlas is based on the data collected by the Clementine mission. It covers the entire Moon in 144 Lunar Aeronautical Charts (LACs), and represents the most complete lunar nomenclature database in existence, listing virtually all named craters and other features. This is the first atlas to show the entire lunar surface in uniform scale and format. A section of color plates shows lunar composition and physical properties.
In the second novel set in the “darkly fascinating world” (SF Site) of Anne Bishop’s Black Jewels Trilogy, ambitions unfurl as the realm’s dreams of a liberator have finally been made flesh... The Blood have waited centuries for the coming of Witch, the living embodiment of magic. But Jaenelle, the young girl singled out by prophecy, is haunted by the cruel battles fought over her—for not all the Blood await her as their Savior. Some dismiss her as a myth. Some refuse to believe. And still others look forward to using her, making her a pawn to their shadowy devices. Only time and the devotion of her loyal guardians have healed Jaenelle’s physical wounds. But her mind is fragile, barely able to protect her from the horrifying memories of her childhood. Nothing, however, can deflect her from her destiny—and the day of reckoning looms near. When her memories return. When her magic matures. When she is forced to accept her fate. On that day, the dark Realms will know what it means to be ruled by Witch.
The Explanatory Supplement provides a detailed description of how to perform practical astronomy or spherical astronomy. This completely revised and rewritten edition is an authoritative source on astronomical phenomena and calendars. Although this paperback edition carries a 2006 copyright date, it is the same material published in 1992 hardcover edition.
Early one May morning in 1874, in the hills above Williamsburg, Massachusetts, a reservoir dam suddenly burst, sending an avalanche of water down a narrow river valley lined with factories and farms. In just thirty minutes, the Mill River flood left 139 people dead and 740 homeless -- and a nation wondering how this terrible calamity had happened. In this compelling tale of a man-made disaster peopled with everyday heroes and arrogant scoundrels, Elizabeth Sharpe opens a rare window into industry and village life in nineteenth-century New England, a time when dam failures and other industrial accidents were widespread and laws favored factory owners rather than factory workers. In the Mill Valley, the townsfolk depended upon generally benevolent patriarchs who assured them that the dam was safe, when most people could see that it was not. The story of the Mill River flood is the story of those townsfolk: of George Cheney, the dam keeper whose repeated warnings about leaks in the dam had been ignored by the mill owners; of his wife, Elizabeth, who watched in disbelief as the dam burst open from the bottom; of Isabell Hayden, the mother who saw her young son swept away in the river's torrent; and of Fred Howard, a box maker who spent the days after the flood searching for bodies, burying friends, and waiting to see if the button factory he relied upon for his livelihood would be rebuilt. It is also the story of the well-meaning but overconfident businessmen who built the dam: of Onslow Spelman, the manufacturer who dismissed the dam keeper's flood warning, irrationally insisting that the dam could not break; of Lucius Fenn and Joel Bassett, the engineer and contractor whose roles in the construction of the dam would be questioned during the public inquest into the causes of the flood; of William Skinner, the factory owner who struggled to decide whether or not to rebuild his silk factory in the village that bore his name; and of many others. The flood highlighted class divisions between worker and owner, as well as the disorganized state of professional engineering, then still in its infancy. As the flood exposed the dangers of allowing mill owners -- who were not trained engineers -- to design their own dam, legislation to regulate the building of reservoir dams in Massachusetts was enacted for the first time. Engineers, politicians, and business owners battled over control of the reform measures to prevent similar tragedies, yet saw them continually repeated. In the Shadow of the Dam is the story of an event that reshaped a society. Told through the eyes of villagers like Collins Graves, lauded as a hero for his desperate ride through the valley to warn people of the impending flood, and industrialists like Joel Hayden Jr., entrusted with the responsibility of disaster relief despite his culpability in failing to maintain the leaking dam, In the Shadow of the Dam is a history of our uneasy relationship with industrial progress and a riveting narrative of a tragic disaster in small-town Massachusetts.
We all want to understand the world around us, and the ancient Greeks were the first to try and do so in a way we can properly call scientific. Their thought and writings laid the essential foundations for the revivals of science in medieval Baghdad and renaissance Europe. Now their work is accessible to all, with this invaluable introduction to c.100 scientific authors active from 320 BCE to 230 CE. The book begins with an outline of a new socio-political model for the development and decline of Greek science, followed by eleven chapters that cover the main disciplines: * the science which the Greeks saw as fundamental - mathematics * astronomy * astrology and geography * mechanics * optics and pneumatics * the non-mathematical sciences of alchemy, biology, medicine and 'psychology'. Each chapter contains an accessible introduction on the origins and development of the topic in question, and all the authors are set in context with brief biographies.
This remarkable volume presents a panorama of geographical writings from Hesiod to Humboldt, from the beginnings of geographical thought in the Western world to the emergence of topical specialization. It includes a wealth of material from non-Western sources, particularly Moslem and Chinese, that has not been collected before. The selections are arranged chronologically, and contain geographical theory, descriptions of terrestrial phenomena by early observers, and excerpts from major voyages of discovery. Some are obvious classics: Socrates on the nature of the Earth, Ezekiel's description of the commerce of Tyre, Columbus' first glimpse of the West Indies, Buffon on the history of the Earth, and Kant's geographical lectures. Yet more commonly, Mr. Kish provides a sense of the discovery with such finds as the ambassador's report to the Caliph of Baghdad on the lands and customs of the Norsemen, the study of the Tartar Empire by John of Monte Corvino, Archbishop of Peking, and Jefferson's private memo to Alexander von Humboldt seeking information on the American West. Each section is highlighted by a brief but engagingly written introduction by the editor. Throughout, the unique cultural and professional perspective of George Kish is very much in evidence.
Taking a comprehensive, nuanced, and inclusive approach to Christopher Columbus, this illuminating biography with activities for young readers places him in the context of the explorations that came before, during, and after his lifetime. It portrays the “Admiral of the Ocean Seas” neither as hero nor heel, but as a flawed and complex man whose significance is undeniably monumental. Providing kids, parents, and teachers with a fuller picture of the seafaring life and the dangers and thrills of exploration, author Ronald Reis details all four of Columbus’s voyages to the New World, not just his first, and describes the year that Columbus spent stranded on the island of Jamaica without hope of rescue. A full chapter is devoted to painting a more complete and complex portrait of the indigenous peoples of the New World and another to the consequences of Columbus’s voyages—the exchange of diseases, ideas, crops, and populations between the New World and the Old. Engaging cross-curricular activities, such as taking nautical measurements, simulating a hurricane, making an ancient globe, and conducting silent trade, elucidate nautical concepts introduced and the times in which Columbus lived.
