When the first underwater “habitat” called Sealab was tested in the early 1960s, conventional dives had strict depth limits and lasted for only minutes, not the hours and even days that the visionaries behind Sealab wanted to achieve—for purposes of exploration, scientific research, and to recover submarines and aircraft that had sunk along the continental shelf. The unlikely father of Sealab, George Bond, was a colorful former country doctor who joined the Navy later in life and became obsessed with these unanswered questions: How long can a diver stay underwater? How deep can a diver go?Sealab never received the attention it deserved, yet the program inspired explorers like Jacques Cousteau, broke age-old depth barriers, and revolutionized deep-sea diving by demonstrating that living on the seabed was not science fiction. Today divers on commercial oil rigs and Navy divers engaged in classified missions rely on methods pioneered during Sealab.Sealab is a true story of heroism and discovery: men unafraid to test the limits of physical endurance to conquer a hostile undersea frontier. It is also a story of frustration and a government unwilling to take the same risks underwater that it did in space.Ben Hellwarth, a veteran journalist, interviewed many surviving participants from the three Sealab experiments and conducted extensive documentary research to write the first comprehensive account of one of the most important and least known experiments in US history.

    The volatile debate was at first carried on in academic journals and in magazines like Nature and Scientific American. It even engaged the attention of leading evolutionists like Nobel Laureate physicist Steven Weinberg and prominent naturalist Stephen Jay Gould. Johnson was invited to debate several of his opponents at universities across the country. And he was himself the subject of debate: Michael Ruse, author of Darwinism Defended, spoke at an annual meeting of the American Association for the Advancement of Science on the topic "Nonliteralist Anti-Evolutionism: The Case of Phillip Johnson."Darwin on Trial also shook up theistic evolutionists. William Hasker (Huntington College, Indiana) in the Christian Scholar's Review, Howard Van Till (Calvin College, Michigan) in First Things and Owen Gingerich (Harvard Center for Astrophysics) in Perspectives on Science & the Christian Faith all published their critiques of Darwin on Trial.Clearly, Johnson's arguments have been taken seriously by Darwinists of every sort. And though at first the mainstream press seemed to be out of earshot (except for reviews in Publisher's Weekly and The National Review), news of Darwin on Trial eventually reached wider audiences. Last summer, Johnson appeared with William F. Buckley on Firing Line. And in May 1995 he was interviewed on the PBS telecast In the Beginning: The Creationist Controversy with Randall Balmer. These and other indications of expanding interest in his critique is good news for all who wish to bring the debate over Darwinism into the bright light of day.

    Today we can see a recreation of the making of the Laetoli footprints at the American Museum of Natural History, in a stunning diorama which depicts two of our human forebears walking side by side through a snowy landscape of volcanic ash. But how do we know what these three-million-year-old relatives looked like? How have we reconstructed the eons-long journey from our first ancient steps to where we stand today? In short, how do we know what we think we know about human evolution? In The Fossil Trail, Ian Tattersall, the head of the Anthropology Department at the American Museum of Natural History, takes us on a sweeping tour of the study of human evolution, offering a colorful history of fossil discoveries and a revealing insider's look at how these finds have been interpreted--and misinterpreted--through time. All the major figures and discoveries are here. We meet Lamarck and Cuvier and Darwin (we learn that Darwin's theory of evolution, though a bombshell, was very congenial to a Victorian ethos of progress), right up to modern theorists such as Niles Eldredge and Stephen Jay Gould. Tattersall describes Dubois's work in Java, the many discoveries in South Africa by pioneers such as Raymond Dart and Robert Broom, Louis and Mary Leakey's work at Olduvai Gorge, Don Johanson's famous discovery of Lucy (a 3.4 million-year-old female hominid, some 40% complete), and the more recent discovery of the Turkana Boy, even more complete than Lucy, and remarkably similar to modern human skeletons. He discusses the many techniques available to analyze finds, from fluorine analysis (developed in the 1950s, it exposed Piltdown as a hoax) and radiocarbon dating to such modern techniques as electron spin resonance and the analysis of human mitochondrial DNA. He gives us a succinct picture of what we presently think our family tree looks like, with at least three genera and perhaps a dozen species through time (though he warns that this greatly underestimates the actual diversity of hominids over the past two million or so years). And he paints a vivid, insider's portrait of paleoanthropology, the dogged work in the broiling sun, searching for a tooth, or a fractured corner of bone, amid stone litter and shadows, with no guarantee of ever finding anything. And perhaps most important, Tattersall looks at all these great researchers and discoveries within the context of their social and scientific milleu, to reveal the insidious ways that the received wisdom can shape how we interpret fossil findings, that what we expect to find colors our understanding of what we do find. Refreshingly opinionated and vividly narrated, The Fossil Trail is the only book available to general readers that offers a full history of our study of human evolution. A fascinating story with intriguing turns along the way, this well-illustrated volume is essential reading for anyone curious about our human origins.

    It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time.The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to theclassification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like D�bereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail.Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successivetheories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr andothers.Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closeswith an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.

    In 1829, a wealthy English naturalist named James Smithson left his library, mineral collection, and entire fortune to "the United States of America, to found ... an establishment for the increase and diffusion of Knowledge among men" -- even though he had never visited the United States or known any Americans. In this fascinating book, Nina Burleigh pieces together the reclusive benefactor's life and painstaking scientific pursuits, and discloses how his bequest was nearly lost due to political infighting until several heroes, including former president John Quincy Adams, saw to it that Smithson's curious notion was realized in 1846. The result was the Smithsonian: a castle housing the United States' first and greatest cultural and scientific establishment, one that has since funded thousands of scientific and exploratory projects around the world and given the nation's capital an enduring cultural foundation.

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.
