Our brains, therefore, are designed not just to hunt and gather, but also to help us get ahead socially, often via deception and self-deception. But while we may be self-interested schemers, we benefit by pretending otherwise. The less we know about our own ugly motives, the better - and thus we don't like to talk or even think about the extent of our selfishness. This is "the elephant in the brain." Such an introspective taboo makes it hard for us to think clearly about our nature and the explanations for our behavior. The aim of this book, then, is to confront our hidden motives directly - to track down the darker, unexamined corners of our psyches and blast them with floodlights. Then, once everything is clearly visible, we can work to better understand ourselves: Why do we laugh? Why are artists sexy? Why do we brag about travel? Why do we prefer to speak rather than listen?Our unconscious motives drive more than just our private behavior; they also infect our venerated social institutions such as Art, School, Charity, Medicine, Politics, and Religion. In fact, these institutions are in many ways designed to accommodate our hidden motives, to serve covert agendas alongside their "official" ones. The existence of big hidden motives can upend the usual political debates, leading one to question the legitimacy of these social institutions, and of standard policies designed to favor or discourage them. You won't see yourself - or the world - the same after confronting the elephant in the brain.

    Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.

    Vygotsky analyzes the relationship between words and consciousness, arguing that speech is social in its origins and that only as children develop does it become internalized verbal thought.Now Alex Kozulin has created a new edition of the original MIT Press translation by Eugenia Hanfmann and Gertrude Vakar that restores the work's complete text and adds materials that will help readers better understand Vygotsky's meaning and intentions. Kozulin has also contributed an introductory essay that offers new insight into the author's life, intellectual milieu, and research methods.

    Indeed, these tiny structures inside our cells are important beyond imagining. Without mitochondria, we would have no cell suicide, no sculpting of embryonic shape, no sexes, no menopause, no aging.In this fascinating and thought-provoking book, Nick Lane brings together the latest research in this exciting field to show how our growing insight into mitochondria has shed light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. These findings are of fundamental importance, both in understanding life on Earth, but also in controlling our own illnesses, and delaying our degeneration and death. Readers learn that two billion years ago, mitochondria were probably bacteria living independent lives and that their capture within larger cells was a turning point in the evolution of life, enabling the development of complex organisms. Lane describes how mitochondria have their own DNA and that its genes mutate much faster than those in the nucleus. This high mutation rate lies behind our aging and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer. We also discover that mitochondrial DNA is passed down almost exclusively via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to "Mitochondrial Eve," giving us vital information about our evolutionary history.Written by Nick Lane, a rising star in popular science, Power, Sex, Suicide is the first book for general readers on the nature and function of these tiny, yet fascinating structures.

    Your brain is a collection of maps. That is no metaphor: scrawled across your brain’s surfaces are actual maps of the sights, sounds, and actions that hold the key to your survival. Scientists first began uncovering these maps over a century ago, but we are only now beginning to unlock their secrets—and comprehend their profound impact on our lives. Brain maps distort and shape our experience of the world, support complex thought, and make technology-enabled mind reading a modern-day reality, which raises important questions about what is real, what is fair, and what is private. They shine a light on our past and our possible futures. In the process, they invite us to view ourselves from a startling new perspective.  ​ In Brainscapes, Rebecca Schwarzlose combines unforgettable real-life stories, cutting-edge research, and vivid illustrations to reveal brain maps’ surprising lessons about our place in the world—and about the world’s place within us.

    Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be reasoned out--from building a bridge to winning a game of anagrams. Generations of readers have relished Polya's deft--indeed, brilliant--instructions on stripping away irrelevancies and going straight to the heart of the problem.

Neurologists must puzzle out life-changing diagnoses from the tiniest of clues. It’s the ultimate medical detective work. In this riveting book, one of the UK’s leading neurologists will take you with her as she follows the clues of her patients’ symptoms. It’s a journey that will open your eyes to the unfathomable intricacies of our brains, and the infinite variety of human capacity and experience.

    The book was based on a course of public lectures delivered by Schrödinger in February 1943 at Trinity College, Dublin. Schrödinger's lecture focused on one important question: "how can the events in space and time which take place within the spatial boundary of a living organism be accounted for by physics and chemistry?" In the book, Schrödinger introduced the idea of an "aperiodic crystal" that contained genetic information in its configuration of covalent chemical bonds. In the 1950s, this idea stimulated enthusiasm for discovering the genetic molecule and would give both Francis Crick and James Watson initial inspiration in their research.

    In the process, the abyss is being revealed as perhaps the most amazing part of our planet, its topography even more varied and extreme than its landmass counterpart.Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more--good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep--many of them incandescent in a world without light--and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines. Yet the deep also holds huge mineral riches lusted after by nations and corporations; mining them could ultimately devastate the planet, compounded by the deepening impacts of ubiquitous pollutants and rampant overfishing.Eloquently and passionately, the author of Spirals in Time and Eye of the Shoal brings to life the majesty and mystery of an alien realm that nonetheless sustains us, while urgently making clear the price we could pay if it is further disrupted. The Brilliant Abyss is at once a revelation and a clarion call to preserve this vast unseen world.

    He takes us on a journey through the laboratories where scientists are studying every aspect of the cell--DNA, mitochondria, stem cells, our immune systems, even age genes that can lead to a tenfold increase in life span (in worms, anyway)--all in an effort to forestall or reverse the body's (currently!) inevitable decline. With clear writing and intellectual passion, Steele shines a spotlight on a revolution already under way and offers reality-based hope.

    But how you do it is one of science's great mysteries. And vision is involved with so much of everything your brain does. Explaining how it works reveals more than just how you see. In We Know It When We See It, Harvard neuroscientist Richard Masland tackles vital questions about how the brain processes information -- how it perceives, learns, and remembers -- through a careful study of the inner life of the eye.Covering everything from what happens when light hits your retina, to the increasingly sophisticated nerve nets that turn that light into knowledge, to what a computer algorithm must be able to do before it can be called truly "intelligent," We Know It When We See It is a profound yet approachable investigation into how our bodies make sense of the world.

    What would you see if you removed the skull from the human brain and then slowly worked your way deeper and deeper into the brain, to the level of an individual neuron? With renowned brain researcher Susan Greenfield as your guide, here is your chance to gain a bird's eye view of the human brain—and to learn more about what the brain is, how it works, what happens when one part of the brain is made dysfunctional through stroke or accident, how brain mood-modifying drugs find their targets.In a particularly fascinating chapter, Greenfield surveys for us how a brain is built and then takes us on a tour of the developing brain from the moment of conception.Throughout Greenfield poses the larger questions all readers want to consider, including: At what stage does individuality creep into the developing brain? How does the collection of circuits of neurons give rise not just to an individual brain but an individual consciousness? What might a fetus be conscious of?
