Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    In captivity, octopuses have been known to identify individual human keepers, raid neighboring tanks for food, turn off lightbulbs by spouting jets of water, plug drains, and make daring escapes. How is it that a creature with such gifts evolved through an evolutionary lineage so radically distant from our own? What does it mean that evolution built minds not once but at least twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter?In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how subjective experience crept into being—how nature became aware of itself. As Godfrey-Smith stresses, it is a story that largely occurs in the ocean, where animals first appeared. Tracking the mind’s fitful development, Godfrey-Smith shows how unruly clumps of seaborne cells began living together and became capable of sensing, acting, and signaling. As these primitive organisms became more entangled with others, they grew more complicated. The first nervous systems evolved, probably in ancient relatives of jellyfish; later on, the cephalopods, which began as inconspicuous mollusks, abandoned their shells and rose above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so. Taking an independent route, mammals and birds later began their own evolutionary journeys.But what kind of intelligence do cephalopods possess? Drawing on the latest scientific research and his own scuba-diving adventures, Godfrey-Smith probes the many mysteries that surround the lineage. How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually “think for themselves”? What happens when some octopuses abandon their hermit-like ways and congregate, as they do in a unique location off the coast of Australia?By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind—and on our own.

    More and more people -- Baby Boomers and information workers in particular -- are becoming concerned about their gray matter's ability to function, and with good reason. As this sensible and entertaining guide points out, your brain is easily your most important possession. It deserves proper upkeep.Your Brain: The Missing Manual is a practical look at how to get the most out of your brain -- not just how the brain works, but how you can use it more effectively. What makes this book different than the average self-help guide is that it's grounded in current neuroscience. You get a quick tour of several aspects of the brain, complete with useful advice about:Brain Food: The right fuel for the brain and how the brain commands hunger (including an explanation of the different chemicals that control appetite and cravings)Sleep: The sleep cycle and circadian rhythm, and how to get a good night's sleep (or do the best you can without it)Memory: Techniques for improving your recallReason: Learning to defeat common sense; logical fallacies (including tactics for winning arguments); and good reasons for bad prejudicesCreativity and Problem-Solving: Brainstorming tips and thinking not outside the box, but about the box -- in other words, find the assumptions that limit your ideas so you can break through themUnderstanding Other People's Brains: The battle of the sexes and babies developing brainsLearn about the built-in circuitry that makes office politics seem like a life-or-death struggle, causes you to toss important facts out of your memory if they're not emotionally charged, and encourages you to eat huge amounts of high-calorie snacks. With Your Brain: The Missing Manual you'll discover that, sometimes, you can learn to compensate for your brain or work around its limitations -- or at least to accept its eccentricities. Exploring your brain is the greatest adventure and biggest mystery you'll ever face. This guide has exactly the advice you need.

    Parlez-vous Doggish? At long last, dogs will know just how smart their owners can be. By unlocking the secrets of the hidden language of dogs, psychologist Stanley Coren allows us into the doggy dialogue, or “Doggish,” and makes effective communication a reality. Drawing on substantial research in animal behavior, evolutionary biology, and years of personal experience, Coren demonstrates that the average house dog can understand language at about the level of a two-year-old human. While actual conversation of the sort Lassie seemed capable of in Hollywood mythmaking remains forever out of reach, Coren shows us that a great deal of real communication is possible beyond the giving and obeying of commands. How to Speak Dog not only provides the sounds, words, actions, and movements with which we can effectively communicate with our dogs, but also deciphers the signs that our dogs give to us. With easy-to-follow tips on how humans can mimic the language dogs use to talk with one another, original drawings illustrating the subtleties of their body language, and a handy visual glossary and “Doggish” phrasebook, How to Speak Dog gives dog lovers the skills they need to improve their relationships with their pets.

    Morell probes the moral and ethical dilemmas of recognizing that even “lesser animals” have cognitive abilities such as memory, feelings, personality, and self-awareness--traits that many in the twentieth century felt were unique to human beings.By standing behaviorism on its head, Morell brings the world of nature brilliantly alive in a nuanced, deeply felt appreciation of the human-animal bond, and she shares her admiration for the men and women who have simultaneously chipped away at what we think makes us distinctive while offering a glimpse of where our own abilities come from.

    As you read this, we are engineering the next stage of human evolution. Through advances in genetic, robotic, information and nanotechnologies, we are altering our minds, our memories, our metabolisms, our personalities, our progeny - and perhaps our very souls.Taking us behind the scenes with today's foremost researchers and pioneers, Garreau reveals that the super powers of our comic-book heroes already exist, or are in development in hospitals, labs, and research facilities around the country -- from the revved up reflexes and speed of Spider-Man and Superman, to the enhanced mental acuity and memory capabilities of an advanced species. Over the next fifteen years, Garreau makes clear, these enhancements will become part of our everyday lives. Where will they lead us? To heaven - where technology's promise to make us smarter, vanquish illness and extend our lives is the answer to our prayers? Or will they lead us, as some argue, to hell - where unrestrained technology brings about the ultimate destruction of our entire species? With the help and insights of the gifted thinkers and scientists who are making what has previously been thought of as science fiction a reality, Garreau explores how these developments, in our lifetime, will affect everything from the way we date to the way we work, from how we think and act to how we fall in love. It is a book about what our world is becoming today, not fifty years out. As Garreau cautions, it is only by anticipating the future that we can hope to shape it.

    Drawing on exclusive accounts from whistleblowers and regulators, as well as thousands of pages of confidential FDA documents, Eban reveals an industry where fraud is rampant, companies routinely falsify data, and executives circumvent almost every principle of safe manufacturing to minimize cost and maximize profit, confident in their ability to fool inspectors. Meanwhile, patients unwittingly consume medicine with unpredictable and dangerous effects.The story of generic drugs is truly global. It connects middle America to China, India, sub-Saharan Africa and Brazil, and represents the ultimate litmus test of globalization: what are the risks of moving drug manufacturing offshore, and are they worth the savings? A decade-long investigation with international sweep, high-stakes brinkmanship and big money at its core, Bottle of Lies reveals how the world’s greatest public-health innovation has become one of its most astonishing swindles.

    Revealing that AD is not one condition, as it is currently treated, but three, The End of Alzheimer's outlines 36 metabolic factors (micronutrients, hormone levels, sleep) that can trigger "downsizing" in the brain. The protocol shows us how to rebalance these factors using lifestyle modifications like taking B12, eliminating gluten, or improving oral hygiene.The results are impressive. Of the first ten patients on the protocol, nine displayed significant improvement with 3-6 months; since then the protocol has yielded similar results with hundreds more. Now, The End of Alzheimer's brings new hope to a broad audience of patients, caregivers, physicians, and treatment centers with a fascinating look inside the science and a complete step-by-step plan that fundamentally changes how we treat and even think about AD.

    He also crystallized one of the most important debates of our time: As we enjoy the Net’s bounties, are we sacrificing our ability to read and think deeply?Now, Carr expands his argument into the most compelling exploration of the Internet’s intellectual and cultural consequences yet published. As he describes how human thought has been shaped through the centuries by “tools of the mind”—from the alphabet to maps, to the printing press, the clock, and the computer—Carr interweaves a fascinating account of recent discoveries in neuroscience by such pioneers as Michael Merzenich and Eric Kandel. Our brains, the historical and scientific evidence reveals, change in response to our experiences. The technologies we use to find, store, and share information can literally reroute our neural pathways.Building on the insights of thinkers from Plato to McLuhan, Carr makes a convincing case that every information technology carries an intellectual ethic—a set of assumptions about the nature of knowledge and intelligence. He explains how the printed book served to focus our attention, promoting deep and creative thought. In stark contrast, the Internet encourages the rapid, distracted sampling of small bits of information from many sources. Its ethic is that of the industrialist, an ethic of speed and efficiency, of optimized production and consumption—and now the Net is remaking us in its own image. We are becoming ever more adept at scanning and skimming, but what we are losing is our capacity for concentration, contemplation, and reflection.Part intellectual history, part popular science, and part cultural criticism, The Shallows sparkles with memorable vignettes—Friedrich Nietzsche wrestling with a typewriter, Sigmund Freud dissecting the brains of sea creatures, Nathaniel Hawthorne contemplating the thunderous approach of a steam locomotive—even as it plumbs profound questions about the state of our modern psyche. This is a book that will forever alter the way we think about media and our minds.

    

    Now Dr. David Grand presents the next leap forward in psychological care—combining the strengths of brain-based and talk therapies into a powerful technique he calls Brainspotting. In Brainspotting, Dr. Grand reveals the key insight that allowed him to develop this revolutionary therapeutic tool: that where we look reveals critical information about what's going on in our brain. Join him to learn about:The history of Brainspotting—how it evolved from EMDR practice as a more versatile tool for brain-based therapy• Brainspotting in action—case studies and evidence for the effectiveness of the technique• An overview of the different aspects of Brainspotting and how to use them• Between sessions—how clients can use Brainspotting on their own to reinforce and accelerate healing• Why working simultaneously with the right and left brain can lead to expanded creativity and athletic performance• How Brainspotting can be used to treat PTSD, anxiety, depression, addiction, physical pain, chronic illness, and much more"Brainspotting lets the therapist and client participate together in the healing process," explains Dr. Grand. "It allows us to harness the brain's natural ability for self-scanning, so we can activate, locate, and process the sources of trauma and distress in the body." With Brainspotting, this pioneering researcher introduces an invaluable tool that can support virtually any form of therapeutic practice—and greatly accelerate our ability to heal.

    Richard Dawkins, for example, jolted us into realizing that we are just survival mechanisms for our own genes, sophisticated robots in service of huge colonies of replicators to whom concepts of rationality, intelligence, agency, and even the human soul are irrelevant.Accepting and now forcefully responding to this decentering and disturbing idea, Keith Stanovich here provides the tools for the "robot's rebellion," a program of cognitive reform necessary to advance human interests over the limited interest of the replicators and define our own autonomous goals as individual human beings. He shows how concepts of rational thinking from cognitive science interact with the logic of evolution to create opportunities for humans to structure their behavior to serve their own ends. These evaluative activities of the brain, he argues, fulfill the need that we have to ascribe significance to human life. We may well be robots, but we are the only robots who have discovered that fact. Only by recognizing ourselves as such, argues Stanovich, can we begin to construct a concept of self based on what is truly singular about humans: that they gain control of their lives in a way unique among life forms on Earth—through rational self-determination.

    These individuals all lost some part of what we think of as our self, but they then offer remarkable, sometimes heart-wrenching insights into what remains. One man cut off his own leg. Another became one with the universe.We are learning about the self at a level of detail that Descartes (“I think therefore I am”) could never have imagined. Recent research into Alzheimer’s illuminates how memory creates your narrative self by using the same part of your brain for your past as for your future. But wait, those afflicted with Cotard’s syndrome think they are already dead; in a way, they believe that “I think therefore I am not.” Who—or what—can say that? Neuroscience has identified specific regions of the brain that, when they misfire, can cause the self to move back and forth between the body and a doppelgänger, or to leave the body entirely. So where in the brain, or mind, or body, is the self actually located? As Ananthaswamy elegantly reports, neuroscientists themselves now see that the elusive sense of self is both everywhere and nowhere in the human brain.

    I’m Tim. I’m a single cell in society’s body. U.S. society, to be specific.So let me explain why we’re here.As a writer and a generally thinky person, I’ve spent a lot of my life thinking about the society I live in, and societies in general. I’ve always imagined society as a kind of giant human—a living organism like each of us, only much bigger.When you’re a single cell in the body of a giant, it’s hard to understand what the giant’s doing, or why it is the way it is, because you can’t really zoom out and look at the whole thing all at once. But we do our best.The thing is, when I’ve recently tried to imagine what society might look like, I haven’t really been picturing this:Giant stick figure: "I am grown up."Based on what I see around me, in person and online, it seems like my society is actually more like this:Giant stick figure throwing a giant tantrum because their chocolate ice cream fell on the ground.Individual humans grow older as they age—but it kind of seems like the giant human I live in has been getting more childish each year that goes by.So I decided to write a blog post about this. But then something else happened.When I told people I was planning to write a post about society, and the way people are acting, and the way the media is acting, and the way the government is acting, and the way everyone else is acting, people kept saying the same thing to me.Don’t do it. Don’t touch it. Write about something else. Anything else. It’s just not worth it.They were right. With so many non-controversial topics to write about, why take on something so loaded and risk alienating a ton of readers? I listened to people’s warnings, and I thought about moving on to something else, but then I was like, “Wait what? I live inside a giant and the giant is having a six-year-old meltdown in the grocery store candy section and that’s a not-okay thing for me to talk about?”It hit me that what I really needed to write about was that—about why it’s perilous to write about society."

    Noble, who argues that the flourishing of both religion and technology today is nothing new but rather the continuation of a 1,000-year-old Western tradition.The Religion of Technology demonstrates that modern man's enchantment with things technological was inspired by and grounded in religious expectations and the quest for transcendence and salvation. The two early impulses behind the urge to advance in science, he claims, are the conviction that apocalypse is imminent, and the belief that increasing human knowledge helps recover what was lost in Eden. Noble traces the history of these ideas by examining the imaginings of monks, explorers, magi, scientists, Freemasons, and engineers, from Sir Isaac Newton to Joseph Priestley to Wernher von Braun.Noble suggests that the relationship between religion and technology has perhaps outlived its usefulness. Whereas it once aimed to promote human well-being, it has ultimately become a threat to our survival. Thus, with The Religion of Technology, Noble aims to redirect our efforts toward more worldly and humane ends.
