Admittedly, computers now play chess at the grandmaster level, but do they understand the game as we do? Can a computer eventually do everything a human mind can do? In this absorbing and frequently contentious book, Roger Penrose--eminent physicist and winner, with Stephen Hawking, of the prestigious Wolf prize--puts forward his view that there are some facets of human thinking that can never be emulated by a machine. Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness. He is among a growing number of physicists who think Einstein wasn't being stubborn when he said his little finger told him that quantum mechanics is incomplete, and he concludes that laws even deeper than quantum mechanics are essential for the operation of a mind. To support this contention, Penrose takes the reader on a dazzling tour that covers such topics as complex numbers, Turing machines, complexity theory, quantum mechanics, formal systems, Godel undecidability, phase spaces, Hilbert spaces, black holes, white holes, Hawking radiation, entropy, quasicrystals, the structure of the brain, and scores of other subjects. The Emperor's New Mind will appeal to anyone with a serious interest in modern physics and its relation to philosophical issues, as well as to physicists, mathematicians, philosophers and those on either side of the AI debate.

    This book shows how easy it is to fill our gardens with everything from foxes, frogs and mice, to butterflies, ladybirds and thousands of fascinating creepy-crawlies.

    New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.

    The Big Questions series is designed to let renowned experts address the 20 most fundamental and frequently asked questions of a major branch of science or philosophy. Each 3,000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, and provides answers based on the latest research. This ambitious project is a unique distillation of humanity's best ideas. In "The Big Questions: Evolution," Francisco Ayala answers the 20 key questions: What is evolution? Was Darwin right? What is natural selection? What is survival of the fittest? Is evolution a random process? What is a species? What are chromosomes, genes and DNA? How do genes build bodies? What is molecular evolution? How did life begin? What is the tree of life? Am I really a monkey? What does the fossil record tell us? What is the missing link? Is intelligence inherited? Will humans continue to evolve? Can I clone myself? Where does morality come from? Is language a uniquely human attribute? Is Creationism true?

    Yet cultural psychologist Steven J. Heine argues that, in trying to know who we are and where we come from, we’re likely to completely misinterpret what’s “in our DNA.” Heine’s fresh, surprising conclusions about the promise, and limits, of genetic engineering and DNA testing upend conventional thinking and reveal a simple, profound truth: your genes create life—but they do not control it.

    

    She loved the ocean and wrote three books about its mysteries, including the international bestseller The Sea Around Us. But it was with her fourth book, Silent Spring, that this unassuming biologist transformed our relationship with the natural world.Rachel Carson began work on Silent Spring in the late 1950s, when a dizzying array of synthetic pesticides had come into use. Leading this chemical onslaught was the insecticide DDT, whose inventor had won a Nobel Prize for its discovery. Effective against crop pests as well as insects that transmitted human diseases such as typhus and malaria, DDT had at first appeared safe. But as its use expanded, alarming reports surfaced of collateral damage to fish, birds, and other wildlife. Silent Spring was a chilling indictment of DDT and its effects, which were lasting, widespread, and lethal.Published in 1962, Silent Spring shocked the public and forced the government to take action-despite a withering attack on Carson from the chemicals industry. The book awakened the world to the heedless contamination of the environment and eventually led to the establishment of the EPA and to the banning of DDT and a host of related pesticides. By drawing frightening parallels between dangerous chemicals and the then-pervasive fallout from nuclear testing, Carson opened a fault line between the gentle ideal of conservation and the more urgent new concept of environmentalism.Elegantly written and meticulously researched, On a Farther Shore reveals a shy yet passionate woman more at home in the natural world than in the literary one that embraced her. William Souder also writes sensitively of Carson's romantic friendship with Dorothy Freeman, and of her death from cancer in 1964. This extraordinary new biography captures the essence of one of the great reformers of the twentieth century.A New York Times Notable Book of 2012“A suspenseful tale of the literary life…utterly inspiring.” —San Francisco Chronicle“Captivating…Souder writes vividly and with great empathy for his subject and her cause.” —New York Times Book Review“A delightful, fascinating, engrossing read about some of the most important insights of modern science. You’ll find yourself thinking about Carson whenever you take a walk in the woods.” —Slate.com

    Now he stands ready to revolutionize both neuroscience and computing in one stroke, with a new understanding of intelligence itself.Hawkins develops a powerful theory of how the human brain works, explaining why computers are not intelligent and how, based on this new theory, we can finally build intelligent machines.The brain is not a computer, but a memory system that stores experiences in a way that reflects the true structure of the world, remembering sequences of events and their nested relationships and making predictions based on those memories. It is this memory-prediction system that forms the basis of intelligence, perception, creativity, and even consciousness.In an engaging style that will captivate audiences from the merely curious to the professional scientist, Hawkins shows how a clear understanding of how the brain works will make it possible for us to build intelligent machines, in silicon, that will exceed our human ability in surprising ways.Written with acclaimed science writer Sandra Blakeslee, On Intelligence promises to completely transfigure the possibilities of the technology age. It is a landmark book in its scope and clarity.

    Healthy soil is teeming with life — not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms. When we use chemical fertilizers, we injure the microbial life that sustains healthy plants, and thus become increasingly dependent on an arsenal of artificial substances, many of them toxic to humans as well as other forms of life. But there is an alternative to this vicious circle: to garden in a way that strengthens, rather than destroys, the soil food web — the complex world of soil-dwelling organisms whose interactions create a nurturing environment for plants. By eschewing jargon and overly technical language, the authors make the benefits of cultivating the soil food web available to a wide audience, from devotees of organic gardening techniques to weekend gardeners who simply want to grow healthy, vigorous plants without resorting to chemicals.

    Two dozen new photos and illustrations make this new edition even richer with information. Its convenient paperback format makes it easy to carry and access, whether you are in or out of the garden. An essential overview of the science behind plants for beginning and advanced gardeners alike.

    Warren Andiman, an HIV/AIDS researcher who has been on the front lines battling infectious diseases for over forty years. In Animal Viruses and Humans: A Narrow Divide, Andiman traces the history of eight zoonotic viruses —deadly microbes that have made the leap directly from animals to human populations: Middle East Respiratory Syndrome (MERS), Swine influenza, Hantavirus, Monkeypox, Severe Acute Respiratory Syndrome (SARS), Rabies, Ebola, and Henipaviruses (Nipah and Hendra). He also illustrates the labor intensive and fascinating detective work that infectious disease specialists must do to uncover the source of an outbreak.Andiman also looks to the future, envisioning the effects on zoonoses (diseases caused by zoonotic viruses) of climate change, microenvironmental damage, population shifts, and globalization. He reveals the steps that we can, and must, take to stem the spread of animal viruses, explaining, “The zoonoses I've chosen to write about . . . are meant to describe only a small sample of what is already out there but, more menacingly, what is inevitably on its way, in forms we can only imagine.” Warren Andiman, MD is professor emeritus of pediatrics and epidemiology at the Yale Schools of Medicine and Public Health.

    That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. In The Soil Will Save Us, journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming.As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

    Line drawings highlight family characteristics, and plant entries discuss medicinal uses, edibility, toxicity, and look-alike plants. A standard reference at herbal and wilderness schools across the country, this resource is essential for herbalists, gardeners, and naturalists.

    Key features include:- use of compatible perennials;- non-invasive planting techniques;- emphasis on biodiversity;- specifically adaptable to local climate, landscape, and soil conditions;- highly productive output of edibles.Now, picture your backyard as one incredibly lush garden, filled with edible flowers, bursting with fruit and berries, and carpeted with scented herbs and tangy salad greens. The visual impact is of Monet's palette, a wash of color, texture, and hue. But this is no still life. The flowers nurture endangered pollinators. Bright-featured songbirds feed on abundant berries and gather twigs for their nests.The plants themselves are grouped in natural communities, where each species plays a role in building soil, deterring pests, storing nutrients, and luring beneficial insects. And finally, you—good ol' homo sapiens—are an integral part of the scene. Your garden tools are resting against a nearby tree, and have a slight patina of rust, because this garden requires so little maintenance. You recline into a hammock to admire your work. You have created a garden paradise.This is no dream, but rather an ecological garden, which takes the principles of permaculture and applies them on a home-scale. There is nothing technical, intrusive, secretive, or expensive about this form of gardening. All that is required is some botanical knowledge (which is in this book) and a mindset that defines a backyard paradise as something other than a carpet of grass fed by MiracleGro.

    For three decades, scientists and the United Nations have urged us to address future existential threats, an effort that culminated in the 2015 Paris Agreement. Although 188 countries made commitments to prevent global warming from exceeding 2 degrees centigrade, as of 2021, 182 failed, and the G7 countries did not even come close. The result so far: 98 percent of the world is disengaged from the greatest danger civilization has ever faced. Instead, extreme weather is increasing, climate migration is disrupting borders and politics in the EU and US, while fossil fuel energy companies dig in their heals to prevent the advent of renewable energy. Journalistic lingo that says we should combat climate change, but by using war metaphors, climate became a story of one more conflict, a framing that has left out humanity.In Regeneration Paul Hawken has flipped the narrative, bringing people back into the conversation by demonstrating that addressing current human needs rather than future threats is the only path to solving the climate crisis. Regeneration is the first book to define, delineate, and set standards for regeneration, offering a comprehensive explanation of its meaning and application Why regeneration? Because every single economic sector in the world extracts life from the planet and by doing so harms it. The way to reverse a heating planet and human indifference is to reverse planetary degeneration.Using regeneration as a foundation for understanding and action includes everyone and shows how people the world over can benefit by creating rather than reacting. Regeneration contains an extraordinary array of initiatives that include but go well beyond solar, electric vehicles, and tree planting to include such solutions as marine protected areas, bioregions, azolla fern, food localization, regenerative agriculture, forest farms, and the #1 solution for the world: electrifying everything.Paul Hawken and the non-profit Regeneration are launching a series of initiatives to accompany the book that will include a streaming video series, curriculum, podcasts, teaching videos, and climate action software. Regeneration is the inspiring and needed guide to inform the burgeoning climate movement.
