Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars--and to think critically about what's out there, no matter how strange it seems.

NATIONAL BESTSELLER • “Exciting and provocative . . . A tour de force of a book that begs to be seen as well as to be read.”— The Washington Post Book World World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits—self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics—are rooted in the deep past, and illuminated by our kinship with other animals. Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

The Beginner Books -- "Their cartoon format and irreverent wit make difficult ideas accessible and entertaining." -- Newsday aking us through the upheavals in biological thought which made The Origins of Species possible, Jonathan Miller introduces us to that odd revolutionary, Charles Darwin -- a remarkably timid man who spent most of his life in seclusion; a semi-invalid riddled with doubts, fearing the controversy his theories might unleash; yet also the man who finally undermined belief in God's creation. Along the way we meet a fascinating cast of characters: Darwin's scientific predecessors, his contemporaries (including Alfred Russell Wallace, whose anticipation of natural selection forced Darwin to publish), his opponents, and his successors whose work in modern genetics provided necessary modifications to Darwin's own work. Splendidly illustrated, this clever, witty, highly informative book is the perfect introduction to Darwin's life and thought.

In these essays Heinz von Foerster discusses some of the fundamental principles that govern how we know the world and how we process the information from which we derive that knowledge. Included are path- breaking articles concerning the principles of computation in neural nets (1967), the definition of self-organizing systems (1960), the nature of cognition (1970), as well as recent expansions on these themes (e.g. "How recursive is communication," 1993). Working with Norbert Wiener, Warren McCullough, and others in the 1960s and 1970s, von Foerster was one of the founders of the science of cybernetics, which has had profound effects both on modern systems theory and on the philosophy of cognition. At the Biological Computer Laboratory at the University of Illinois he produced the first parallel computers and contributed to many other developments in the theory of computation and cognition.

Spaceflight historian Amy Shira Teitel tells the riveting story of the female pilots who each dreamed of being the first American woman in space. When the space age dawned in the late 1950s, Jackie Cochran held more propeller and jet flying records than any pilot of the twentieth century-man or woman. She had led the Women's Auxiliary Service Pilots during the Second World War, was the first woman to break the sound barrier, ran her own luxury cosmetics company, and counted multiple presidents among her personal friends. She was more qualified than any woman in the world to make the leap from atmosphere to orbit. Yet it was Jerrie Cobb, twenty-five years Jackie's junior and a record-holding pilot in her own right, who finagled her way into taking the same medical tests as the Mercury astronauts. The prospect of flying in space quickly became her obsession. While the American and international media spun the shocking story of a "woman astronaut" program, Jackie and Jerrie struggled to gain control of the narrative, each hoping to turn the rumored program into their own ideal reality-an issue that ultimately went all the way to Congress. This dual biography of audacious trailblazers Jackie Cochran and Jerrie Cobb presents these fascinating and fearless women in all their glory and grit, using their stories as guides through the shifting social, political, and technical landscape of the time.

"Orenstein is such a breezy, funny writer, it's easy to forget she's an important thinker too."--People In this lively, funny memoir, Peggy Orenstein sets out to make a sweater from scratch--shearing, spinning, dyeing wool--and in the process discovers how we find our deepest selves through craft. Orenstein spins a yarn that will appeal to everyone. The COVID pandemic propelled many people to change their lives in ways large and small. Some adopted puppies. Others stress-baked. Peggy Orenstein, a lifelong knitter, went just a little further. To keep herself engaged and cope with a series of seismic shifts in family life, she set out to make a garment from the ground up: learning to shear sheep, spin and dye yarn, then knitting herself a sweater. Orenstein hoped the project would help her process not just wool but her grief over the recent death of her mother and the decline of her dad, the impending departure of her college-bound daughter, and other thorny issues of aging as a woman in a culture that by turns ignores and disdains them. What she didn't expect was a journey into some of the major issues of our time: climate anxiety, racial justice, women's rights, the impact of technology, sustainability, and, ultimately, the meaning of home. With her wry voice, sharp intelligence, and exuberant honesty, Orenstein shares her year-long journey as daughter, wife, mother, writer, and maker--and teaches us all something about creativity and connection.

A fascinating tribute to the forefathers of two of today’s most exciting scientific fields Thanks to Max Delbruck and George Gamow, today we have mapped the human genome and understand the ramifications of the Big Bang. In his characteristically inviting and elegant style, Gino Segre brings to life the story of these two great scientists and their long friendship and offers an accessible inside look the people behind the scenes of science—the collaboration and competition, the quirks and failures, the role of intuition and luck, and the sense of wonder and curiosity that keeps these extraordinary minds going.

In this modern era of mathematical modeling, applications have become increasingly complicated. As the complexity grows, it becomes more and more difficult to draw meaningful conclusions about the behavior of theoretical models and their relations to reality. Alongside methods that emphasize quantitative properties and the testing of scientific details, there is a need for approaches that are more qualitative. These techniques attempt to cover whole families of models in one bold stroke, in a manner that allows robust conclusions to be drawn about them. Loop analysis and time averaging provide a means of interpreting the properties of systems from the network of interactions within the system. The authors' methodology concentrates on graphical representation to guide experimental design, to identify sources of external variability from the statistical pattern of variables, and to make management decisions. Although most of the examples are drawn from ecology, the methods are relevant to all of the pure and applied sciences. This relevance is enhanced by case studies from such diverse areas as physiology, resource management, the behavioral sciences, and social epidemiology. The book will be useful to a broad readership from the biological and social sciences as well as the physical sciences and technology. It will interest undergraduate and graduate students along with researchers active in these disciplines. Here the reader will find a strong rationale for maintaining a holistic approach, revealing what insights and advantages are retained by the broader perspective and, more explicitly, by the synergistic effects that cannot be discerned by reducing systems to their smallest parts.

2018 Reprint of 1962 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. Bookchin wrote Our Synthetic Environment under the pseudonym Lewis Herber. This was one of the first books of the modern period in which an author espoused an ecological and environmentalist worldview. It predates Silent Spring (1962) by Rachel Carson, a more widely known book on the same topic widely credited as starting the environmental movement. "At the time of its publication, Our Synthetic Environment was the most comprehensive and enlightened book on the environmental crisis. Many other books on this topic have been published since, but none, I believe, as comprehensive." --René Dubos

This volume contains material first presented at an international workshop on the 'Use of Microorganisms to Combat Pollution', held in Israel, May 10--18, 1992. The workshop was sponsored by the Bat-Sheva de Rothschild Foundation for the Advancement of Science and included microbiologists, biochemists and geneticists from universities, environmental agencies and the military. Each of the contributors to this volume is an ack nowledged expert on the treatment of one or more types of pollution using microorganisms or their enzymes. This book differs from most published symposia proceedings in the breadth of coverage of each subject. Most of the chapters are divided into three parts: (a) A general presentation of the source and toxicity of the pollutant, (b) a review of the current state-of-the-science on the biodegradation of that pollutant and (c) the authors' unique research experiences on the problem. In several examples, the authors have presented data from both laboratory studies and field trials. Thus, the book contains not only the theoretical background on the biodegradation of pollutants, but also practical experiences in applying this knowledge to solving significant pollution problems.

The Negev , first published over a decade ago, told the story of some twenty years of study of southern Israel's desert. It synthesized the findings of botanists, geologists, soil scientists, agronomists, archaeologists, historians, and engineers and told how the applications of their work produced an agricultural surplus in this forbiddingly dry, hot region. , Now Michael Evenari has amplified the book with data from another decade of work. He describes the efforts at a new farm at Wadi Mashash, extends the weather data another ten years, presents further work on the adaptations of plants and animals to desert conditions, and takes a much deeper look at the historical precedents for the method of runoff agriculture, which has made the desert bloom.

The Symposium on the Global Effects of Environmental Pollution has performed an important task; it has helped to determine the world-wide impact of certain types of local pollution and has uncovered certain unsuspected effects that might hold dan gerous implications for the future. This Symposium should help to make the world aware of a crisis that is becoming more ominous and that involves the developing as well as the developed countries - the crisis of the human environment. The causes of this crisis are not difficult to discern. There has been an unprecedented increase in the world's population, an ever-increasing rate of urbanization, and in many countries, a continuous process of industrialization. Essentially, advancing technology has made it possible for a minority of mankind to achieve affluence and holds out hope for improving the well-being of the great majority. But, because it has not been integrated into the natural environment, this very technology - in industry, in agriculture or in transport - is having many undesir able and potentially catastrophic consequences. Our air, our water and our soil are in grave danger. Many species of animal and plant life have become extinct or are facing extinction. The loss to mankind is grave and even the future oflife on earth may be in danger. The challenge is to find ways of repairing the harm already done and to prevent further harm.
