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.

"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.

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.

Rapid advances in the physical and biological sciences and in related technologies have brought about equally farreaching changes in mathematical research. Focusing on control theory, invariant imbedding, dynamic programming, and quasilinearization, Mr. Bellman explores with ease and clarity the mathematical research problems arising from scientific questions in engineering, physics, biology, and medicine. Special attention is paid in these essays to the use of the digital computer in obtaining the numerical solution of numerical problems, its influence in the formulation of new and old scientific problems in new terms, and to some of the effects of the computer revolution on educational and social systems. The new opportunities for mathematical research presage, Bellman concludes, a renaissance of mathematics in human affairs by involving it closely in the problems of society.

Menaḥem Mendel Schneerson (1902-1994) was the seventh and seemingly last Rebbe of the Habad-Lubavitch dynasty. Marked by conflicting tendencies, Schneerson was a radical messianic visionary who promoted a conservative political agenda, a reclusive contemplative who built a hasidic sect into an international movement, and a man dedicated to the exposition of mysteries who nevertheless harbored many secrets. Schneerson astutely masked views that might be deemed heterodox by the canons of orthodoxy while engineering a fundamentalist ideology that could subvert traditional gender hierarchy, the halakhic distinction between permissible and forbidden, and the social-anthropological division between Jew and Gentile. While most literature on the Rebbe focuses on whether or not he identified with the role of Messiah, Elliot R. Wolfson, a leading scholar of Jewish mysticism and the phenomenology of religious experience, concentrates instead on Schneerson's apocalyptic sensibility and his promotion of a mystical consciousness that undermines all discrimination. For Schneerson, the ploy of secrecy is crucial to the dissemination of the messianic secret. To be enlightened messianically is to be delivered from all conceptual limitations, even the very notion of becoming emancipated from limitation. The ultimate liberation, or true and complete redemption, fuses the believer into an infinite essence beyond all duality, even the duality of being emancipated and not emancipated--an emancipation, in other words, that emancipates one from the bind of emancipation. At its deepest level, Schneerson's eschatological orientation discerned that a spiritual master, if he be true, must dispose of the mask of mastery. Situating Habad's thought within the evolution of kabbalistic mysticism, the history of Western philosophy, and Mahayana Buddhism, Wolfson articulates Schneerson's rich theology and profound philosophy, concentrating on the nature of apophatic embodiment, semiotic materiality, hypernomian transvaluation, nondifferentiated alterity, and atemporal temporality.

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.
