A new interpretation of nearly 40 years of interstellar signals and the prophetic message
In 1900 a group of sponge divers blown off course in the Mediterranean discovered an Ancient Greek shipwreck dating from around 70 BC. Lying unnoticed for months amongst their hard-won haul was what appeared to be a formless lump of corroded rock, which turned out to be the most stunning scientific artefact we have from antiquity. For more than a century this 'Antikythera mechanism' puzzled academics, but now, more than 2000 years after the device was lost at sea, scientists have pieced together its intricate workings. Unmatched in complexity for 1000 years, it was able to predict eclipses and track the paths of the Sun and the Moon through the zodiac, and probably even showed ancient astronomers the movements of the five known planets. In Decoding the Heavens, Jo Marchant tells for the first time the story of the 100-year quest to understand this ancient computer. Along the way she unearths a diverse cast of remarkable characters - ranging from Archimedes to Jacques Cousteau - and explores the deep roots of modern technology not only in ancient Greece but in the Islamic world and medieval Europe too. At heart an epic adventure story, it is a book that challenges our assumptions about technology transfer over the ages while giving us fresh insights into history itself.

The author of Zero explains the scientific revolution that is transforming the way we understand our world Previously the domain of philosophers and linguists, information theory has now moved beyond the province of code breakers to become the crucial science of our time. In Decoding the Universe, Charles Seife draws on his gift for making cutting-edge science accessible to explain how this new tool is deciphering everything from the purpose of our DNA to the parallel universes of our Byzantine cosmos. The result is an exhilarating adventure that deftly combines cryptology, physics, biology, and mathematics to cast light on the new understanding of the laws that govern life and the universe. .
While on assignment in Greece, journalist James Nestor witnessed something that confounded him: a man diving 300 feet below the ocean's surface on a single breath of air and returning four minutes later, unharmed and smiling.This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic's greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes--deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species' remarkable, and often hidden, potential--including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.
Launched in 2005, the Genographic Project is the largest genetic study of human migration ever mounted. In this accessible text, Project Director and National Geographic Explorer-in-Residence Spencer Wells provides an overview of what is understood so far and describes what scientists hope to learn as the project progresses. He uses the stories of five individual program participants as examples for explaining how historical details are gleaned from DNA and exploring the larger issues involved in the research.

At the center of Deep Blue Home--a penetrating exploration of the ocean as single vast current and of the creatures dependent on it--is Whitty's description of the three-dimensional ocean river, far more powerful than the Nile or the Amazon, encircling the globe. It's a watery force connected to the earth's climate control and so to the eventual fate of the human race. Whitty's thirty-year career as a documentary filmmaker and diver has given her sustained access to the scientists dedicated to the study of an astonishing range of ocean life, from the physiology of "extremophile" life forms to the strategies of nesting seabirds to the ecology of "whale falls" (what happens upon the death of a behemoth). No stranger to extreme adventure, Whitty travels the oceanside and underwater world from the Sea of Cortez to Newfoundland to Antarctica. In the Galapagos, in one of the book's most haunting encounters, she realizes: "I am about to learn the answer to my long-standing question about what would happen to a person in the water if a whale sounded directly alongside--would she, like a person afloat beside a sinking ship, be dragged under too?" This book provides extraordinary armchair entree to gripping adventure, cutting-edge science, and an intimate understanding of our deep blue home.

Deep Freeze: The United States, the International Geophysical Year, and the Origins of Antarctica's Age of Scienceby Dian Olson Belanger
Dian Olson Belanger tells the story of the pioneers who built viable communities, made vital scientific discoveries, and established Antarctica as a continent dedicated to peace and the pursuit of science, decades after the first explorers planted flags in the ice. In the tense 1950s, even as the world was locked in the Cold War, U.S. scientists, maintained by the Navy's Operation Deep Freeze, came together in Antarctica with counterparts from eleven other countries to participate in the International Geophysical Year (IGY). On July 1, 1957, they began systematic, simultaneous scientific observations of the south-polar ice and atmosphere. Their collaborative success over eighteen months inspired the Antarctic Treaty of 1959, which formalized their peaceful pursuit of scientific knowledge. Still building on the achievements of the individuals and distrustful nations thrown together by the IGY from mutually wary military, scientific, and political cultures, science prospers today and peace endures. The year 2007 marked the fiftieth anniversary of the IGY and the commencement of a new International Polar Year - a compelling moment to review what a singular enterprise accomplished in a troubled time. Belanger draws from interviews, diaries, memoirs, and official records to weave together the first thorough study of the dawn of Antarctica's scientific age. Deep Freeze offers absorbing reading for those who have ventured onto Antarctic ice and those who dream of it, as well as historians, scientists, and policy makers
For years, Derrick Jensen has asked his audiences, "Do you think this culture will undergo a voluntary transformation to a sane and sustainable way of life?" No one ever says yes.Deep Green Resistance starts where the environmental movement leaves off: industrial civilization is incompatible with life. Technology can't fix it, and shopping--no matter how green--won't stop it. To save this planet, we need a serious resistance movement that can bring down the industrial economy. Deep Green Resistance evaluates strategic options for resistance, from nonviolence to guerrilla warfare, and the conditions required for those options to be successful. It provides an exploration of organizational structures, recruitment, security, and target selection for both aboveground and underground action. Deep Green Resistance also discusses a culture of resistance and the crucial support role that it can play.Deep Green Resistance is a plan of action for anyone determined to fight for this planet--and win.
Although the ability to retain, process, and project prior experience onto future situations is indispensable, the human mind also possesses the ability to override experience and adapt to changing circumstances. Cognitive scientist Stellan Ohlsson analyzes three types of deep, non-monotonic cognitive change: creative insight, adaptation of cognitive skills by learning from errors, and conversion from one belief to another, incompatible belief. For each topic, Ohlsson summarizes past research, re-formulates the relevant research questions, and proposes information-processing mechanisms that answer those questions. The three theories are based on the principles of redistribution of activation, specialization of practical knowledge, and re-subsumption of declarative information. Ohlsson develops the implications of those mechanisms by scaling their effects with respect to time, complexity, and social interaction. The book ends with a unified theory of non-monotonic cognitive change that captures the abstract properties that the three types of change share.
If there were a canon for viewing the night sky, Charles Messier would be its author. The galaxies, star clusters, and nebulae cataloged by the famous comet hunter in the late 1700s are still the most widely observed celestial wonders in the heavens. They are the favorite targets of amateur astronomers, with such rich variety and detail that they never cease to fascinate. This book provides new and experienced observers with a fresh perspective on the Messier objects. Stephen James O'Meara has prepared a visual feast for the observer. Using the finest optical telescopes available for amateur work, he describes and sketches the view from the telescope as never before. There are new drawings, improved finder charts, and new astronomical data on each object, including findings from the Hubble Space Telescope. Expand your universe and test your viewing acumen with this truly modern Messier Guide. It is a must for budding night watchers. Stephen James O'Meara is a contributing editor to Sky and Telescope.
In this fresh list, Stephen James O'Meara presents 109 new objects for stargazers to observe. The Secret Deep list contains many exceptional objects, including a planetary nebula whose last thermal pulse produced a circumstellar shell similar to the one expected in the final days of our Sun's life; a piece of the only supernova remnant known visible to the unaided eye; the flattest galaxy known; the largest edge-on galaxy in the heavens; the brightest quasar; and the companion star to one of the first black hole candidates ever discovered. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical information to enrich the observing experience. Featuring galaxies, clusters and nebulae not covered in other Deep-Sky Companions books, this is a wonderful addition to the series and an essential guide for any deep-sky observer.
Deep-Sky Video Astronomy is a concise guide to using modern integrating video cameras for deep-sky viewing and imaging with the kinds of modest telescopes available commercially to amateur astronomers. It includes an introduction and a brief history of the technology, camera types, etc. The authors then examine the pros and cons of this unrefrigerated yet highly efficient technology, which is already beginning to compete with expensive astronomical cooled-chip CCD cameras in quality and ease of use. There is a thorough examination of accessories used to achieve particular results. Examples are focal reducers, Barlow lenses, and optical filters. However, the focus is mostly on the practical side of creating beautiful and detailed astronomical portraits using image-stacking software, enhancement tools like PhotoShop, and creating color images with a black-and-white camera. Practical step-by-step examples supported by tried and trusted tips show how to achieve the best possible deep-sky video portrait!
The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes - all based on current physics - and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek's 'warp drive') and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.
Humanity's attempts to communicate with itself across ages and to communicate with other spieces across space
On April 20, 2010, the Macondo well blew out, costing the lives of 11 men, and beginning a catastrophe that sank theDeepwater Horizondrilling rig and spilled nearly 5 million barrels of crude oil into the Gulf of Mexico. The spill disrupted an entire region's economy, damaged fisheries and critical habitats, and brought vividly to light the risks of deepwater drilling for oil and gas--the latest frontier in the national energy supply. Soon after, President Barack Obama appointed a seven-member Commission to investigate the disaster, analyze its causes and effects, and recommend the actions necessary to minimize such risks in the future. The Commission's report offers the American public and policymakers alike the fullest account available of what happened in the Gulf and why, and proposes actions--changes in company behavior, reform of government oversight, and investments in research and technology--required as industry moves forward to meet the nation's energy needs.
InThe Deepest Wounds, Thomas D. Rogers traces social and environmental changes over four centuries in Pernambuco, Brazil's key northeastern sugar-growing state. Focusing particularly on the period from the end of slavery in 1888 to the late twentieth century, when human impact on the environment reached critical new levels, Rogers confronts the day-to-day world of farming--the complex, fraught, and occasionally poetic business of making sugarcane grow. Renowned Brazilian sociologist Gilberto Freyre, whose home state was Pernambuco, observed, "Monoculture, slavery, and latifundia--but principally monoculture--they opened here, in the life, the landscape, and the character of our people, the deepest wounds. " Inspired by Freyre's insight, Rogers tells the story of Pernambuco's wounds, describing the connections among changing agricultural technologies, landscapes and human perceptions of them, labor practices, and agricultural and economic policy. This web of interrelated factors, Rogers argues, both shaped economic progress and left extensive environmental and human damage. Combining a study of workers with analysis of their landscape, Rogers offers new interpretations of crucial moments of labor struggle, casts new light on the role of the state in agricultural change, and illuminates a legacy that influences Brazil's development even today.

Voted one of Christianity Today's 1998 Books of the Year!For decades, Christians have felt voiceless in the critical debate over evolution. Until now. Finally, ordinary Christians have the opportunity and the resources to defeat the false claims of Darwinism. With all of the complicated scientific debate swirling around the topic of evolution, Christians need an easy way to understand the basic issues without oversimplifying. Phillip Johnson has the answer: the key to defeating the false claims of Darwinism is to open our minds to good thinking habits. Here is first-rate advice on avoiding common mistakes in discussions about evolution, understanding the legacy of the Scopes trial, spotting deceptive arguments, and grasping the basic scientific issues without getting bogged down in unnecessary details. In the bestselling and critically acclaimed Darwin on Trial and Reason in the Balance, Phillip Johnson took on the academic elites and exposed the misleading claims of evolutionary naturalism. Defeating Darwinism by Opening Minds provides a new and powerful treatment of these issues for high-school students, parents, teachers, pastors, youth advisors and ordinary readers. Johnson aims not just to defeat a bad theory, but to defeat it in the right way-by opening minds to the truth.
For decades it has been nearly universal dogma among environmentalists and health advocates that cattle and beef are public enemy number one. But is the matter really so clear cut? Hardly, argues environmental lawyer turned rancher Nicolette Hahn Niman in her new book, Defending Beef. The public has long been led to believe that livestock, especially cattle, erode soils, pollute air and water, damage riparian areas, and decimate wildlife populations. In Defending Beef, Hahn Niman argues that cattle are not inherently bad for either the Earth or our own nutritional health. In fact, properly managed livestock play an essential role in maintaining grassland ecosystems by functioning as surrogates for herds of wild ruminants that once covered the globe. Hahn Niman argues that dispersed, grass-fed, small-scale farms can and should become the basis for American food production, replacing the factory farms that harm animals and the environment. The author--a longtime vegetarian--goes on to dispel popular myths about how eating beef is bad for our bodies. She methodically evaluates health claims made against beef, demonstrating that such claims have proven false. She shows how foods from cattle--milk and meat, particularly when raised entirely on grass--are healthful, extremely nutritious, and an irreplaceable part of the world's food system. Grounded in empirical scientific data and with living examples from around the world, Defending Beef builds a comprehensive argument that cattle can help to build carbon-sequestering soils to mitigate climate change, enhance biodiversity, help prevent desertification, and provide invaluable nutrition. Defending Beef is simultaneously a book about big ideas and the author's own personal tale--she starts out as a skeptical vegetarian and eventually becomes an enthusiastic participant in environmentally sustainable ranching. While no single book can definitively answer the thorny question of how to feed the Earth's growing population, Defending Beef makes the case that, whatever the world's future food system looks like, cattle and beef can and must be part of the solution.
Hans Reichenbach, a philosopher of science who was one of five students in Einstein's first seminar on the general theory of relativity, became Einstein's bulldog, defending the theory against criticism from philosophers, physicists, and popular commentators. This 2006 book chronicles the development of Reichenbach's reconstruction of Einstein's theory in a way that clearly sets out all of its philosophical commitments and its physical predictions as well as the battles that Reichenbach fought on its behalf, in both the academic and popular press. The essays include reviews and responses to philosophical colleagues; polemical discussions with physicists Max Born and D. C. Miller; as well as popular articles meant for the layperson. At a time when physics and philosophy were both undergoing revolutionary changes in content and method, this book is a window into the development of scientific philosophy and the role of the philosopher.
The United States spends approximately four million dollars each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
Sweeping in scope, penetrating in analysis, and generously illustrated with examples from the history of science, this new and original approach to familiar questions about scientific evidence and method tackles vital questions about science and its place in society. Avoiding the twin pitfalls of scientism and cynicism, noted philosopher Susan Haack argues that, fallible and flawed as they are, the natural sciences have been among the most successful of human enterprises-valuable not only for the vast, interlocking body of knowledge they have discovered, and not only for the technological advances that have improved our lives, but as a manifestation of the human talent for inquiry at its imperfect but sometimes remarkable best.This wide-ranging, trenchant, and illuminating book explores the complexities of scientific evidence, and the multifarious ways in which the sciences have refined and amplified the methods of everyday empirical inquiry; articulates the ways in which the social sciences are like the natural sciences, and the ways in which they are different; disentangles the confusions of radical rhetoricians and cynical sociologists of science; exposes the evasions of apologists for religious resistance to scientific advances; weighs the benefits and the dangers of technology; tracks the efforts of the legal system to make the best use of scientific testimony; and tackles predictions of the eventual culmination, or annihilation, of the scientific enterprise.Writing with verve and wry humor, in a witty, direct, and accessible style, Haack takes readers beyond the "Science Wars" to a balanced understanding of the value, and the limitations, of the scientific enterprise.
Since its publication in the mid-eighteenth century, Hume's discussion of miracles has been the target of severe and often ill-tempered attacks. In this book, one of our leading historians of philosophy offers a systematic response to these attacks. Arguing that these criticisms have--from the very start--rested on misreadings, Robert Fogelin begins by providing a narrative of the way Hume's argument actually unfolds. What Hume's critics (and even some of his defenders) have failed to see is that Hume's primary argument depends on fixing the appropriate standards of evaluating testimony presented on behalf of a miracle. Given the definition of a miracle, Hume quite reasonably argues that the standards for evaluating such testimony must be extremely high. Hume then argues that, as a matter of fact, no testimony on behalf of a religious miracle has even come close to meeting the appropriate standards for acceptance. Fogelin illustrates that Hume's critics have consistently misunderstood the structure of this argument- and have saddled Hume with perfectly awful arguments not found in the text. He responds first to some early critics of Hume's argument and then to two recent critics, David Johnson and John Earman. Fogelin's goal, however, is not to "bash the bashers," but rather to show that Hume's treatment of miracles has a coherence, depth, and power that makes it still the best work on the subject.
