Its starting point is the annual Turing Test, which pits artificial intelligence programs against people to determine if computers can “think.”Named for computer pioneer Alan Turing, the Tur­ing Test convenes a panel of judges who pose questions—ranging anywhere from celebrity gossip to moral conundrums—to hidden contestants in an attempt to discern which is human and which is a computer. The machine that most often fools the panel wins the Most Human Computer Award. But there is also a prize, bizarre and intriguing, for the Most Human Human.In 2008, the top AI program came short of passing the Turing Test by just one astonishing vote. In 2009, Brian Christian was chosen to participate, and he set out to make sure Homo sapiens would prevail.The author’s quest to be deemed more human than a com­puter opens a window onto our own nature. Interweaving modern phenomena like customer service “chatbots” and men using programmed dialogue to pick up women in bars with insights from fields as diverse as chess, psychiatry, and the law, Brian Christian examines the philosophical, bio­logical, and moral issues raised by the Turing Test.One central definition of human has been “a being that could reason.” If computers can reason, what does that mean for the special place we reserve for humanity?

    But are there limits to what we can discover about our physical universe?In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data.Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding?In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there’s anything we truly cannot know.

    Why, then, do their designs diverge so sharply? Humans, for instance, love right angles, while nature's angles are rarely right and usually rounded. Our technology goes around on wheels—and on rotating pulleys, gears, shafts, and cams—yet in nature only the tiny propellers of bacteria spin as true wheels. Our hinges turn because hard parts slide around each other, whereas nature's hinges (a rabbit's ear, for example) more often swing by bending flexible materials. In this marvelously surprising, witty book, Steven Vogel compares these two mechanical worlds, introduces the reader to his field of biomechanics, and explains how the nexus of physical law, size, and convenience of construction determine the designs of both people and nature. "This elegant comparison of human and biological technology will forever change the way you look at each."—Michael LaBarbera, American Scientist

    What it has not done is consider the stark reality that most of the time we humans are thinking about social processes, comparing ourselves to and estimating the intentions of others. In Human, Gazzaniga explores a number of related issues, including what makes human brains unique, the importance of language and art in defining the human condition, the nature of human consciousness, and even artificial intelligence.

    New technologies have revealed secrets locked in prehistoric bones that no one could have previously predicted. We can now work out the color of dinosaurs, the force of their bite, their top speeds, and even how they cared for their young.Remarkable new fossil discoveries—giant sauropod dinosaur skeletons in Patagonia, dinosaurs with feathers in China, and a tiny dinosaur tail in Burmese amber—remain the lifeblood of modern paleobiology. Thanks to advances in technologies and methods, however, there has been a recent revolution in the scope of new information gleaned from such fossil finds.In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs’ lives from their fossils—their colors, their growth, and even whether we will ever be able to bring them back to life. Benton’s account shows that, though extinct, dinosaurs are still very much a part of our world.

    It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    Turner's clear, insightful prose and Anton's masterly illustrations combine to offer specialists and newcomers alike an accurate and accessible guide to the evolution of cats.

    Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.

    From the Space Shuttle training toilet to a crash test of NASA’s new space capsule, Mary Roach takes us on the surreally entertaining trip into the science of life in space and space on Earth.

    From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy.Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world’s most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

    In Missing Microbes, Dr. Martin Blaser invites us into the wilds of the human microbiome where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the health and equilibrium of our body. Now, this invisible eden is being irrevocably damaged by some of our most revered medical advances—antibiotics—threatening the extinction of our irreplaceable microbes with terrible health consequences. Taking us into both the lab and deep into the fields where these troubling effects can be witnessed firsthand, Blaser not only provides cutting edge evidence for the adverse effects of antibiotics, he tells us what we can do to avoid even more catastrophic health problems in the future. http://us.macmillan.com/missingmicrob...

    Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. As Zuk argues, such beliefs incorrectly assume that we’re stuck—finished evolving—and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults’ ability to drink milk to the texture of our ear wax to show that we’ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were “meant to” fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs.From debunking the caveman diet to unraveling gender stereotypes, Zuk gives an analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future.

    This change is being driven by powerful new cognitive tools, enabled by the internet, which are greatly accelerating scientific discovery. There are many books about how the internet is changing business or the workplace or government. But this is the first book about something much more fundamental: how the internet is transforming the nature of our collective intelligence and how we understand the world.Reinventing Discovery tells the exciting story of an unprecedented new era of networked science. We learn, for example, how mathematicians in the Polymath Project are spontaneously coming together to collaborate online, tackling and rapidly demolishing previously unsolved problems. We learn how 250,000 amateur astronomers are working together in a project called Galaxy Zoo to understand the large-scale structure of the Universe, and how they are making astonishing discoveries, including an entirely new kind of galaxy. These efforts are just a small part of the larger story told in this book--the story of how scientists are using the internet to dramatically expand our problem-solving ability and increase our combined brainpower.This is a book for anyone who wants to understand how the online world is revolutionizing scientific discovery today--and why the revolution is just beginning.

    "A gem…An unforgettable account of one of the great moments in the history of human thought." —Steven PinkerProbing the life and work of Kurt Gödel, Incompleteness indelibly portrays the tortured genius whose vision rocked the stability of mathematical reasoning—and brought him to the edge of madness.

    But the theory of evolution did not spring full-blown from the head of Darwin. Since the dawn of humanity, priests, philosophers, and scientists have debated the origin and development of life on earth, and with modern science, that debate shifted into high gear.In this lively, deeply erudite work, Pulitzer Prize–winning science historian Edward J. Larson takes us on a guided tour of Darwin’s “dangerous idea,” from its theoretical antecedents in the early nineteenth century to the brilliant breakthroughs of Darwin and Wallace, to Watson and Crick’s stunning discovery of the DNA double helix, and to the triumphant neo-Darwinian synthesis and rising sociobiology today.Along the way, Larson expertly places the scientific upheaval of evolution in cultural perspective: the social and philosophical earthquake that was the French Revolution; the development, in England, of a laissez-faire capitalism in tune with a Darwinian ethos of “survival of the fittest”; the emergence of Social Darwinism and the dark science of eugenics against a backdrop of industrial revolution; the American Christian backlash against evolutionism that culminated in the famous Scopes trial; and on to today’s world, where religious fundamentalists litigate for the right to teach “creation science” alongside evolution in U.S. public schools, even as the theory itself continues to evolve in new and surprising directions.Throughout, Larson trains his spotlight on the lives and careers of the scientists, explorers, and eccentrics whose collaborations and competitions have driven the theory of evolution forward. Here are portraits of Cuvier, Lamarck, Darwin, Wallace, Haeckel, Galton, Huxley, Mendel, Morgan, Fisher, Dobzhansky, Watson and Crick, W. D. Hamilton, E. O. Wilson, and many others. Celebrated as one of mankind’s crowning scientific achievements and reviled as a threat to our deepest values, the theory of evolution has utterly transformed our view of life, religion, origins, and the theory itself, and remains controversial, especially in the United States (where 90% of adults do not subscribe to the full Darwinian vision). Replete with fresh material and new insights, Evolution will educate and inform while taking readers on a fascinating journey of discovery.From the Hardcover edition.
