Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. Quanta, under editor-in-chief Thomas Lin, is the only popular publication that offers in-depth coverage of today's challenging, speculative, cutting-edge science. It communicates science by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.In the title story, Alice and Bob--beloved characters of various thought experiments in physics--grapple with gravitational forces, possible spaghettification, and a massive wall of fire as Alice jumps into a black hole. Another story considers whether the universe is impossible, in light of experimental results at the Large Hadron Collider. We learn about quantum reality and the mystery of quantum entanglement; explore the source of time's arrow; and witness a eureka moment when a quantum physicist exclaims: "Finally, we can understand why a cup of coffee equilibrates in a room." We reflect on humans' enormous skulls and the Brain Boom; consider the evolutionary benefits of loneliness; peel back the layers of the newest artificial-intelligence algorithms; follow the "battle for the heart and soul of physics"; and mourn the disappearance of the "diphoton bump," revealed to be a statistical fluctuation rather than a revolutionary new particle. These stories from Quanta give us a front-row seat to scientific discovery.ContributorsPhilip Ball, K. C.

    In The Missing Lynx, Ross Barnett uses case studies, new fossil discoveries, biomolecular evidence and more to paint pictures of these extinct species, and to explore the significance of the lynx's disappearance in ecological terms. He also discusses how the Britons that these animals shared their home with might have viewed them, and why some survived while others vanished.Barnett also looks in detail and the realistic potential of reintroductions and even of resurrection--topics that capture public interest today. With Beaver now wild again in various parts of Britain and even Great Bustard on Salisbury Plain, what about the return of sabretooths, mammoths, and the aurochs to modern ecosystems? Will we ever be able to bring these animals back? And should we?At a time where rewilding is moving from pie-in-the-sky to actual reality, this timely and important book looks from a scientific perspective at the magnificent megafauna we've lost, why we lost it and what happened as a result, and how we might realistically turn the ecological tide.

    Fossey's extraordinary efforts to ensure the future of the rain forest and its remaining mountain gorillas are captured in her own words and in candid photographs of this fascinating endangered species. As only she could, Fossey combined her personal adventure story with groundbreaking scientific reporting in an unforgettable portrait of one of our closest primate relatives. Although Fossey's work ended tragically in her murder, Gorillas in the Mist remains an invaluable testament to one of the longest-running field studies of primates and reveals her undying passion for her subject.

    In this lucid and revealing book, Marcus argues that the mind is not an elegantly designed organ but rather a “kluge,” a clumsy, cobbled-together contraption. He unveils a fundamentally new way of looking at the human mind -- think duct tape, not supercomputer -- that sheds light on some of the most mysterious aspects of human nature.Taking us on a tour of the fundamental areas of human experience -- memory, belief, decision-making, language, and happiness -- Marcus reveals the myriad ways our minds fall short. He examines why people often vote against their own interests, why money can’t buy happiness, why leaders often stick to bad decisions, and why a sentence like “people people left left” ties us in knots even though it’s only four words long.Marcus also offers surprisingly effective ways to outwit our inner kluge, for the betterment of ourselves and society. Throughout, he shows how only evolution -- haphazard and undirected -- could have produced the minds we humans have, while making a brilliant case for the power and usefulness of imperfection.

    The "star" of the show is the star-nosed mole, with its nose containing some 25,000 touch-sensitive nerve organs and the ability to gobble small invertebrate prey in world record-breaking time. The mole was author's first real biological assignment; his "strange path of discovery" is brilliantly documented, from figuring how to find and capture his elusive subject to eventually mapping its brain. He also studies tentacled snakes that deploy some devilish hunting strategies, worms that leave the ground in response to "grunts," eels that paralyze their prey with Taser-like jolts, bloodthirsty water shrews, and zombie-making wasps. The author's witty style and amazing findings are complemented by stunning photography and movie shorts that readers with smart phones can scan and play. The astonishing animals are only half the story. Just as compelling is the enquiring-human side--i.e., seeing a scientist at work (and at play), applying a Sherlockian credo

    Ironically, it has also been one of the most misunderstood and abused. Indeed, the rabbit is the only animal that our culture adores as a pet, idolizes as a storybook hero and slaughters for commercial purposes. Stories Rabbits Tell takes a comprehensive look at the rabbit as a wild animal, ancient symbol, pop culture icon, commercial “product” and domesticated pet. In so doing, the book explores how one species can be simultaneously adored as a symbol of childhood (think Peter Rabbit), revered as a symbol of female sexuality (e.g., Playboy Bunnies), dismissed as a “dumb bunny” in domesticity and loathed as a pest in the wild. The authors counter these stereotypes with engaging analyses of real rabbit behavior, drawn both from the authors' own experience and from academic studies, and place those behaviors in the context of current debates about animal consciousness. In a detailed investigative section, the authors also describe conditions in the rabbit meat, fur, pet and vivisection industries, and raise important questions about the ethics of treating rabbits as we do. The first book of its kind, Stories Rabbits Tell provides invaluable information and insight into the life and history of an animal whom many love, but whom most of us barely know. As such, it is a key addition to the current thinking on animal emotions, intelligences and welfare, and the way that human perceptions influence the treatment of individual species.

    For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence? Jeff Hawkins and his team discovered that the brain uses maplike structures to build a model of the world-not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought.

    Most philosophers believe that our experience is locked inside our skulls, an unreliable representation of a quite different reality outside. Colour, smell and sound, they tell us, occur only in our heads. Yet when neuroscientists look inside our brains to see what’s going on, they find only billions of neurons exchanging electrical impulses and releasing chemical substances.Out of My Head tells the gripping, highly personal, often surprisingly funny, story of Tim Parks' quest to discover more about this fascinating topic. It frames complex metaphysical considerations and technical laboratory experiments in terms we can all understand. Above all, it invites us to see space, time, colour and smell, sounds and sensations in an entirely new way. The world will feel more real after reading it.

    Anthony Brandt and David Eagleman rifle through the inventions of human society like paleontologists ransacking the fossil record. Exploring examples from Apollo 13 to Pablo Picasso, they seek to answer the question: what lies at the heart of humanity's ability--and drive--to create? If you took a snapshot of any animal species' behavior, from apes to barnacles, and contrasted it with the same species 10,000 years ago, they'd all be carrying on pretty much as usual (and if they aren't, it's likely due to human influence). Humanity, on the other hand, would be nearly unrecognizable. Above all else, our drive to create is what makes us unique among all living things. Yet where does this all creation, innovation, and change come from? Why us? And if we better understand this -cognitive software-, can we harness it more responsibly to improve our lives, schools, businesses and institutions? Brandt and Eagleman examine hundreds of examples of human creativity through dramatic storytelling and stunning images in this beautiful, full-color volume. By drawing out what creative acts have in common and viewing them through the lens of cutting-edge neuroscience, they uncover the essential elements of this critical human ability, and encourage a more creative future for all of us.

     Early studies of the functions of the human brain used a simple method: wait for misfortune to strike-strokes, seizures, infectious diseases, lobotomies, horrendous accidents-and see how the victim coped. In many cases survival was miraculous, and observers could only marvel at the transformations that took place afterward, altering victims' personalities. An injury to one section can leave a person unable to recognize loved ones; some brain trauma can even make you a pathological gambler, pedophile, or liar. But a few scientists realized that these injuries were an opportunity for studying brain function at its extremes. With lucid explanations and incisive wit, Sam Kean explains the brain's secret passageways while recounting forgotten stories of common people whose struggles, resiliency, and deep humanity made modern neuroscience possible.

    Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science.In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and builds on the latest research to propose a new model for how consciousness works. Bor argues that this brain-based faculty evolved as an accelerated knowledge gathering tool. Consciousness is effectively an idea factory -- that choice mental space dedicated to innovation, a key component of which is the discovery of deep structures within the contents of our awareness.This model explains our brains"; ravenous appetite for information -- and in particular, its constant search for patterns. Why, for instance, after all our physical needs have been met, do we recreationally solve crossword or Sudoku puzzles? Such behavior may appear biologically wasteful, but, according to Bor, this search for structure can yield immense evolutionary benefits -- it led our ancestors to discover fire and farming, pushed modern society to forge ahead in science and technology, and guides each one of us to understand and control the world around us. But the sheer innovative power of human consciousness carries with it the heavy cost of mental fragility.Bor discusses the medical implications of his theory of consciousness, and what it means for the origins and treatment of psychiatric ailments, including attention-deficit disorder, schizophrenia, manic depression, and autism. All mental illnesses, he argues, can be reformulated as disorders of consciousness -- a perspective that opens up new avenues of treatment for alleviating mental suffering.A controversial view of consciousness, The Ravenous Brain links cognition to creativity in an ingenious solution to one of science's biggest mysteries.

    The down beats of their wings would chill the air beneath and create a thundering roar that would drown out all other sound. Feeding flocks would appear as “a blue wave four or five feet high rolling toward you.”John James Audubon, impressed by their speed and agility, said a lone passenger pigeon streaking through the forest “passes like a thought.” How prophetic-for although a billion pigeons crossed the skies 80 miles from Toronto in May of 1860, little more than fifty years later passenger pigeons were extinct. The last of the species, Martha, died in captivity at the Cincinnati Zoo on September 1, 1914.As naturalist Joel Greenberg relates in gripping detail, the pigeons' propensity to nest, roost, and fly together in vast numbers made them vulnerable to unremitting market and recreational hunting. The spread of railroads and telegraph lines created national markets that allowed the birds to be pursued relentlessly. Passenger pigeons inspired awe in the likes of Audubon, Henry David Thoreau, James Fenimore Cooper, and others, but no serious effort was made to protect the species until it was way too late. Greenberg's beautifully written story of the passenger pigeon provides a cautionary tale of what happens when species and natural resources are not harvested sustainably.

    As a young ornithology instructor at the Hog Island Audubon Camp, Dr. Stephen W. Kress learned that puffins had nested on nearby islands until extirpated by hunters in the late 1800s. To right this environmental wrong, he resolved to bring puffins back to one such island—Eastern Egg Rock. Yet bringing the plan to reality meant convincing skeptics, finding resources, and inventing restoration methods at a time when many believed in “letting nature take its course.” Today, Project Puffin has restored more than 1,000 puffin pairs to three Maine islands. But even more exciting, techniques developed during the project have helped to restore rare and endangered seabirds worldwide. Further, reestablished puffins now serve as a window into the effects of global warming. The success of Dr. Kress’s project offers hope that people can restore lost wildlife populations and the habitats that support them. The need for such inspiration has never been greater.

    For the past ten years, some of the people who cycle in and out of the severely ill wards of the Douglas Institute in Montreal, have found a friend in Susan, who volunteers on the ward, and then follows her friends out into the world as they struggle to get through their days. With their full cooperation, she brings us their stories, which challenge the ways we think about people with mental illness on every page. The spine of the book is the life of Caroline Evans (not her real name), a woman in her early sixties whom Susan has known since she was a bright and sunny school girl. Caroline has given Susan complete access to her medical files and her court records; through her, we experience what living with schizophrenia over time is really like. She has been through it all, including the way the justice system treats the severely mentally ill: at one point, she believed that she could save her roommate from the devil by pouring boiling water into her ear... Susan interleaves Caroline's story with vignettes about her other friends, human stories that reveal their hopes, their circumstances, their personalities, their humanity. She's found that if she can hang in through the first ten to fifteen minutes of every coffee date with someone in the grip of psychosis, then true communication results. Their "madness" is not otherworldly: instead it tells us something about how they're surviving their lives and what they've been through.

    As Professor of Anatomy and Forensic Anthropology, she focuses on mortal remains in her lab, at burial sites, at scenes of violence, murder and criminal dismemberment, and when investigating mass fatalities due to war, accident or natural disaster. In All that Remains she reveals the many faces of death she has come to know, using key cases to explore how forensic science has developed, and what her work has taught her. Do we expect a book about death to be sad? Macabre? Sue’s book is neither. There is tragedy, but there is also humour in stories as gripping as the best crime novel. Our own death will remain a great unknown. But as an expert witness from the final frontier, Sue Black is the wisest, most reassuring, most compelling of guides.
