Phantoms In The Brain, using a series of case histories, introduces strange and unexplored mental worlds. Ramachandran, through his research into brain damage, has discovered that the brain is continually organising itself in response to change. A woman maintains that her left arm is not paralysed, a young man loses his right arm in a motorcycle accident, yet he continues to feel a phantom arm with vivid sensation of movement. In a series of experiments using nothing more than Q-tips and dribbles of warm water the young man helped Ramachandran discover how the brain is remapped after injury. Ramachandran believes that cases such as these illustrate fundamental principles of how the human brain operates. The brain ‘needs to create a "script" or a story to make sense of the world, a unified and internally consistent belief system.’ Ramachandran’s radical new approach will have far-reaching effects.
The editors of this book invited some of the most distinguished cognitive scientists of our day to be frankly speculative about how they see their field in the year 2001. Contributors discuss topics that range from artificial intelligence and memory to gene splicing and cognitive development. Whilst wide ranging, the central theme is the nature of human cognition - and the nature of the field of cognitive psychology - and how they may change over the next century.
This book provides a lens through which modern society is shown to depend on complex networks for its stability. One way to achieve this understanding is through the development of a new kind of science, one that is not explicitly dependent on the traditional disciplines of biology, economics, physics, sociology and so on; a science of networks. This text reviews, in non-mathematical language, what we know about the development of science in the twenty-first century and how that knowledge influences our world. In addition, it distinguishes the two-tiered science of the twentieth century, based on experiment and theory (data and knowledge) from the three-tiered science of experiment, computation and theory (data, information and knowledge) of the twenty-first century in everything from psychophysics to climate change.This book is unique in that it addresses two parallel lines of argument. The first line is general and intended for a lay audience, but one that is scientifically sophisticated, explaining how the paradigm of science has been changed to accommodate the computer and large-scale computation. The second line of argument addresses what some consider the seminal scientific problem of climate change. The authors show how a misunderstanding of the change in the scientific paradigm has led to a misunderstanding of complex phenomena in general, and the causes of global warming in particular.
A fascinating exploration of how losing our sense of smell can shape our world, and how the global pandemic transformed our understanding of this mysterious sense.
Alice Roberts has been travelling the world - from Ethiopian desert to Malay peninsula and from Russian steppes to Amazon basin - in order to understand the challenges that early humans faced as they tried to settle continents. On her travels she has witnessed some of the daunting and brutal challenges our ancestors had to face: mountains, deserts, oceans, changing climates, terrifying giant beasts and volcanoes. But she discovers that perhaps the most serious threat of all came from other humans. When our ancestors set out from Africa there were already two other species of human on the planet: Neanderthal in Europe and Homo erectus in Asia. Both (contrary to popular perception) were intelligent, adept at making tools and weapons and were long adapted to their environments. So, Alice asks, why did only Homo sapiens survive? Part detective story, part travelogue, and drawing on the latest genetic and archaeological discoveries, Alice examines how our ancestors evolved physically in response to these challenges, finding out how our colour, shape, size, diet, disease resistance and even athletic ability have been shaped by the range of environments that our ancestors had to survive. She also relates how astonishingly closely related we all are. As a lecturer in Anatomy at Bristol University, Alice Roberts is eminently qualified to write this book. As a talented artist, she is perfectly qualified to illustrate it, and dotted throughout this lively book are many of the sketches and photographs from her travels.
From the author of The Tipping Point, Malcolm Gladwell's international bestseller Blink: The Power of Thinking Without Thinking is a revolution in the understanding of the mind. An art expert sees a ten-million-dollar sculpture and instantly spots it's a fake. A marriage analyst knows within minutes whether a couple will stay together. A fire-fighter suddenly senses he has to get out of a blazing building. A speed dater clicks with the right person... This book is all about those moments when we 'know' something without knowing why. Here Malcolm Gladwell explores the phenomenon of 'blink', showing how a snap judgement can be far more effective than a cautious decision. By trusting your instincts, he reveals, you'll never think about thinking in the same way again.
As the most comprehensive introduction to Brazil available in English, Brazil: The Once and Future Country shows Brazil to be a land of the marvelous and the mystical, the sublime and the tragic. Marshall Eakin describes a country defined by paradoxes: immense wealth surrounded by widespread poverty, a modern industrial infrastructure alongside an outmoded agricultural system, a largely white South and a Northeastern coast that is overwhelmingly of African descent. Eakin chronicles Brazil’s development from its origins in the sixteenth century, when it was created as a by-product of European imperial expansion, to the present day. He takes the reader from the hovels of São Paolo to the pleasure palaces of Rio de Janeiro and all places in between to show the rich cultural mix that is Brazil. Brazil: The Once and Future Country is a fascinating read that anyone interested in Brazil will want. It is also the perfect book for the traveler, armchair or otherwise, interested in this endlessly fascinating country.
Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Are our space and time unique, or could there be other, parallel worlds with their own space and time? Do space and time really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions, and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. No prior knowledge of philosophy is required to enjoy this book. The universe might seem very different after reading it.
What exactly is human ageing? Can it be slowed down? These questions have puzzled scientists and laymen alike for generations, and continue to do so today. The author addresses these thought-provoking issues by challenging pre-conceived notions of age-perception, age-acceptance and inter-age relations. Pertinent matters of age-related communication are dealt with, and the reader is treated to a grand tour of the latest theories of ageing, age-related biological changes and age-related diseases, such as Alzheimer's Disease. Here, the author's expertise in age-related eye diseases truly comes into its own. Weale's unique work not only underlines important genetic and avoidable risk factors but gives ample consideration to possible consequences stemming from different early lifestyles. Readers will re-consider their ideas of what it means to age, and gain a better understanding of what can and cannot slow down the process of ageing.

This book traces the history of ideas about the nature of matter and also the way that mankind has used material resources that the world offers. Starting with the ideas of ancient civilizations that air, earth, fire and water were the basic ingredients of all matter, it traces the development of the science of chemistry beginning within the ranks of the alchemists. First, the idea of elements grew and then the atomic nature of matter was verified. Physicists had entered the scene, showing the nature of atoms in terms of fundamental particles and then introducing the concept of wave-particle duality that altered the basic concepts of what matter was. Finally the physicists discovered a panoply of fundamental particles, some observed within atom-smashing machines and the existence of others merely postulated. In parallel with the above there is a description of various kinds of matter as it affects everyday life, including the nature of matter associated with life itself. The way that early man used the materials directly given by nature, such as stone, wood and animal skins, is followed by the use of materials requiring some process to be employed, e.g. metals which include bronze and also concrete. Some important modern materials are discussed, such as synthetic fibres and plastics and semiconductors, and potentially important future products from new developments in nanotechnology.

***A Waterstones Best Books of 2022 pick*** A New Scientist Book of the Year Shortlisted for the Wainwright Prize for Conservation Writing 'Fascinating... There is something wondrous in Milman's revelation of our fragile dependency on insect life as well as its beauty and strangeness.' Guardian 'Gripping and especially unnerving.' David Wallace-Wells When is the last time you were stung by a wasp? Or were followed by a cloud of midges? Or saw a butterfly? All these normal occurrences are becoming much rarer. A groundswell of research suggests insect numbers are in serious decline all over the world - in some places by over 90%. The Insect Crisis explores this hidden emergency, arguing that its consequences could even rival climate change. We rely on insect pollination for the bulk of our agriculture, they are a prime food source for birds and fish, and they are a key strut holding up life on Earth, especially our own. In a compelling and entertaining investigation spanning the globe, Milman speaks to the scientists and entomologists studying this catastrophe and asks why these extraordinary creatures are disappearing. Part warning, part celebration of the incredible variety of insects, this book highlights why we need to wake up to this impending environmental disaster.
Every day, most of us will read or watch something in the news that is based on statistics in some way. Sometimes it'll be obvious - 'X people develop cancer every year' - and sometimes less obvious - 'How smartphones destroyed a generation'. Statistics are an immensely powerful tool for understanding the world, but in the wrong hands they can be dangerous. Introducing you to the common mistakes that journalists make and the tricks they sometimes deploy, HOW TO READ NUMBERS is a vital guide that will help you understand when and how to trust the numbers in the news - and, just as importantly, when not to.
This book recalls, for nonscientific readers, the history of quantum mechanics, the main points of its interpretation, and Einstein's objections to it, together with the responses engendered by his arguments. Most popular discussions on the strange aspects of quantum mechanics ignore the fundamental fact that Einstein was correct in his insistence that the theory does not directly describe reality. While that fact does not remove the theory's counterintuitive features, it casts them in a different light.Context is provided by following the history of two central aspects of physics: the elucidation of the basic structure of the world made up of particles, and the explanation, as well as the prediction, of how objects move. This history, prior to quantum mechanics, reveals that whereas theories and discoveries concerning the structure of nature became increasingly realistic, the laws of motion, even as they became more powerful, became more and more abstract and remote from intuitive notions of reality. Newton's laws of motion gained their abstract power by sacrificing direct and intuitive contact with real experience. Arriving 250 years after Newton, the break with a direct description of reality embodied in quantum mechanics was nevertheless profound.

'Beautiful . . . Justifies its place alongside nature writing classics such as H is for Hawk' NEW STATESMAN 'Wonderful ... both frank and fearless' TELEGRAPH BEST TRAVEL BOOKS OF THE YEAR 'Fascinating' GUARDIAN TOP TEN NATURE MEMOIRS From Mexico to the Arctic ice, grey whale mothers swim with their calves. Following them, by bus, train and ferry, are Doreen and her toddler Max, in pursuit of a wild hope. Doreen first visited Alaska as a young journalist reporting on climate change among indigenous whaling communities. There, drawn deeply into an Iñupiaq family, she joined the bowhead whale hunt, watching for polar bears under the never-ending light. Years later, now a single mother living in a hostel, Doreen embarks on this extraordinary journey: following the grey whale migration back to the Arctic, where greys and bowheads meet at the melting apex of our planet. 'Soundings got under my skin. I finished it in tears' AMY LIPTROT 'What a voice! What a book!' CHARLES FOSTER 'Soulful, honest, insightful, humane and propulsive' JINI REDDY 'Thrilling, passionate and tender-hearted' HELEN JUKES WINNER OF THE RSL GILES ST AUBYN AWARD ONE OF SMITHSONIAN MAGAZINE'S TEN BEST BOOKS ABOUT TRAVEL OF 2022
This book addresses some of the baffling questions encountered at the final frontier of space and time related to particle physics and cosmology in the context of recent iconoclastic observations and developments. When particle physics stagnated in the early seventies, a new development emerged - String Theory.For the past 25 years, String Theory, popularly called the "Theory of Everything", has mesmerized not just scientists, but also the general public. Yet a closer scrutiny today reveals that it is no more than a mathematical marvel. It has neither predicted anything nor has it been anywhere near verification. We are essentially where we were in the early seventies.Another chronic problem that Einstein had abandoned was the unified description of his theory of General Relativity that deals with the Universe at large and Electromagnetism which is to do with particles. Such a description is necessary even if it warrants a radical departure from our time-honoured ideas of space and time. A bright spot has now appeared in Cosmology. Iconoclastic observations in the past years have shown that the Universe is actually accelerating, driven by a mysterious Dark Energy. This book takes the lay reader through these uncharted waters and mind-boggling developments on an unimaginable journey from the ultra small to the farthest stretches conceivable, via such imagination defying concepts as extra dimensions and multiple universes.
A SPECTATOR BOOK OF THE YEAR 2022 'A thrilling deep-dive through our evolutionary past, and a witty and learned commentary on why we are the way we are - and what wisdom we've lost along the way' Cal Flynn, author of Islands of Abandonment 'A wild ride: brave, outrageous, hilarious, helpful and urgent ... essential reading' Merlin Sheldrake, author of Entangled Lives What kind of creature is a human? If we don't know what we are, how can we know how to act? Charles Foster sets out to understand what a human is, inhabiting the sensory worlds of humans at three pivotal moments in our history. Foster begins his quest with his son in a Derbyshire wood, trying to find a way of experiencing the world that recognises the deep expanse of time when we understood ourselves as hunter-gatherers, and when modern consciousness was first ignited. From there he travels to the Neolithic, a way of being defined by fences, farms, sky gods and slaughterhouses, and finally to the Enlightenment, when we decided that the universe was a machine and we were soulless cogs within it.
The iconic futurist artist and designer Syd Mead once described science fiction as 'reality ahead of schedule'. In From Science Fiction to Science Fact, Levy explores the visions of the writers, futurists and far-sighted inventors who made those realities, from the direct influence of H.G. Wells on the atomic bomb and the tank, to the ambitious prototypes created by inventors ahead of their time, such as Nikola Tesla's remote-controlled drone ships. The history and development of each technology is detailed and related in context, exploring the road from prescient fictional representation to real-life technology. Meet the greatest names and works in sci-fi, from Jules Verne and Aldous Huxley to Arthur C. Clarke and Isaac Asimov, Star Trek to the Bionic Man, alongside visionary inventors such as Tesla and Wernher von Braun.

"Fascinating and exhilarating-Sean B. Carroll at his very best."-Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the world Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.
A revealing and entertaining guide through some of the biggest misconceptions in science that many of us still believe. You may well be familiar with the fact that lightning, contrary to the popular saying, often strikes the same place twice. But this is just the tip of the iceberg when it comes to what many of us wrongly believe about the way the world works. Whether it's word of mouth, myths you've read about online, or misremembered facts from school, we're bombarded by misconceptions about the science we come into contact with every day - this book will uncover the most popular myths to help you avoid contributing to the perpetuation of these misunderstandings. Breaking it down into fifty of the most popular misconceptions in science, each chapter of this book will be headed up with a 'fact', followed by the real story, providing the science and theory that debunks the myth. From fears about the exponential growth of the human population to the embarrassment of always pointing out the north star as the brightest in the sky, this is the book to read if you want to separate the science fact from fiction.
The theory of nonlinear, complex systems has become by now a proven problem-solving approach in the natural sciences. And it is now also recognized that many if not most of our social, ecological, economical and political problems are essentially of a global, complex and nonlinear nature. And it is now further accepted than any holistic perspective of the human mind and brain can hardly be achieved by any other approach. In this wide-ranging, scholarly but very concise treatment, physicist, computer scientist and philosopher Klaus Mainzer discusses, in essentially nontechnical language, the common framework behind these ideas and challenges. Emphasis is given to the evolution of new structures in natural and cultural systems and we are lead to see clearly how the new integrative approach can give insights not available from traditional reductionistic methods. The fifth edition enlarges and revises almost all sections and supplements an entirely new chapter on the complexity of economic systems. From the reviews of the fourth edition: "This book is ambitious, incredibly erudite with 22 pages of references, and is indisputably clearly and beautifully written and illustrated. It is perfectly suited to a first course on the science of complexity. Even beginners and young graduate students will have something to learn from this book." (Andre Hautot, Physicalia, Vol. 57 (3), 2005) "All-in-all, this highly recommended book is a wonderful resource for intuitive basic ideas in the need of rigorous formulation." (Albert A. Mullin, Zentralblatt MATH, vol. 1046, 2004) "Readers of this book will enjoy Mainzer's exposition, which is based on a tight coupling between classical andhistorical concepts from Plato and Aristotle to modern, mathematical and physical developments . Every chapter begins with a section designed to orient the reader to the perspective of philosophical developments through the ages pertinent to the topic at hand. The author takes pains to point out essential differences between classical science and the science of complexity. Thinking in Complexity is an outstandingly readable book." (Anutosh Moitra, The Industrial Physicist, August/September, 2004)
'Half Lives shines a light on the shocking history of the world's toxic love affair with a deadly substance, radium. Unnerving, fascinating, informative and truly frightening.' Hallie Rubenhold, author of The Five 'The story of this supposed cure-all in everyday 20th century life is fascinating and well told.' Brian Maye, Irish Times Lucy Jane Santos presents the surprising history of radium in everyday life. Of all the radioactive elements discovered at the end of the 19th century, it was radium that became the focus of both public fascination and entrepreneurial zeal. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in- the-dark dance costume - to its role as a supposed cure-all in everyday 20th-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element, and enthusiastic customers welcomed their radioactive wares into their homes. Historian Lucy Jane Santos - herself the proud owner of a formidable collection of radium beauty treatments - delves into the stories of these products and details the gradual downfall and discredit of the radium industry through the eyes of the people who bought, sold and eventually came to fear the once-fetishized substance. She reveals a new history of radium, one in which the stories of those previously dismissed as quacks and fools are brought to life, as part of a unique examination of the interplay between science and popular culture.
New in paperback by Laurence Gardner, the bestselling author of Bloodline of the Holy Grail. From the tombs of pharaonic Egypt, to the laboratories of modern science, comes the extraordinary account of gravity defiance and teleportation in the ancient world, and amazing revelations about the past power and future significance of the sacred Ark. The sacred Ark of the Covenant, created from a legendary substance, is the source of one of the deepest mysteries of the Western world. No reason is given in the Bible as to why the Ark of the Covenant was so richly contrived, and no explanation exists of its alleged awesome and deadly powers. Laurence Gardner has accessed Rosicrucian archives in liaison with eminent nuclear physicists to reveal where the ark is, what it is, and how this lost secret of the distant past, has led to the phenomenal new science of space-time manipulation. Gardner's controversial research reveals that the secret of the pharaohs' rite of passage to the Afterlife was due to an amazing magical substance, which was directly associated with the pyramids and the biblical Ark of the Covenant. This substance, now known to be superconductive monatomic gold, became know as the Philosophers' Stone, while in today's corridors of quantum mechanics its attributes are classified as 'the most remarkable physical property in the universe'." |
