Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people. People with failing eyesight, paradoxically, may become immersed in a hallucinatory visual world. Hallucinations can be brought on by a simple fever or even the act of waking or falling asleep, when people have visions ranging from luminous blobs of color to beautifully detailed faces or terrifying ogres. Those who are bereaved may receive comforting “visits” from the departed. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one’s own body. Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them. As a young doctor in California in the 1960s, Oliver Sacks had both a personal and a professional interest in psychedelics. These, along with his early migraine experiences, launched a lifelong investigation into the varieties of hallucinatory experience. Here, with his usual elegance, curiosity, and compassion, Dr. Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organization and structure of our brains, how they have influenced every culture’s folklore and art, and why the potential for hallucination is present in us all, a vital part of the human condition.

    Darwin was only too aware of the storm his theory of evolution would provoke but he would surely have raised an incredulous eyebrow at the controversy still raging a century and a half later. Evolution is accepted as scientific fact by all reputable scientists and indeed theologians, yet millions of people continue to question its veracity.In The Greatest Show on Earth Richard Dawkins takes on creationists, including followers of ‘Intelligent Design’ and all those who question the fact of evolution through natural selection. Like a detective arriving on the scene of a crime, he sifts through fascinating layers of scientific facts and disciplines to build a cast-iron case: from the living examples of natural selection in birds and insects; the ‘time clocks’ of trees and radioactive dating that calibrate a timescale for evolution; the fossil record and the traces of our earliest ancestors; to confirmation from molecular biology and genetics. All of this, and much more, bears witness to the truth of evolution.The Greatest Show on Earth comes at a critical time: systematic opposition to the fact of evolution is now flourishing as never before, especially in America. In Britain and elsewhere in the world, teachers witness insidious attempts to undermine the status of science in their classrooms. Richard Dawkins provides unequivocal evidence that boldly and comprehensively rebuts such nonsense. At the same time he shares with us his palpable love of the natural world and the essential role that science plays in its interpretation. Written with elegance, wit and passion, it is hard-hitting, absorbing and totally convincing.

    Though he never left Italy, his inventions and discoveries were heralded around the world. Most sensationally, his telescopes allowed him to reveal a new reality in the heavens and to reinforce the astounding argument that the Earth moves around the Sun. For this belief, he was brought before the Holy Office of the Inquisition, accused of heresy, and forced to spend his last years under house arrest. Of Galileo's three illegitimate children, the eldest best mirrored his own brilliance, industry, and sensibility, and by virtue of these qualities became his confidante. Born Virginia in 1600, she was thirteen when Galileo placed her in a convent near him in Florence, where she took the most appropriate name of Suor Maria Celeste. Her loving support, which Galileo repaid in kind, proved to be her father's greatest source of strength throughout his most productive and tumultuous years. Her presence, through letters which Sobel has translated from their original Italian and masterfully woven into the narrative, graces her father's life now as it did then. Galileo's Daughter dramatically recolors the personality and accomplishment of a mythic figure whose seventeenth-century clash with Catholic doctrine continues to define the schism between science and religion. Moving between Galileo's grand public life and Maria Celeste's sequestered world, Sobel illuminates the Florence of the Medicis and the papal court in Rome during the pivotal era when humanity's perception of its place in the cosmos was being overturned. In that same time, while the bubonic plague wreaked its terrible devastation and the Thirty Years' War tipped fortunes across Europe, one man sought to reconcile the Heaven he revered as a good Catholic with the heavens he revealed through his telescope. With all the human drama and scientific adventure that distinguished Longitude, Galileo's Daughter is an unforgettable story.

    His quick mastery of quantum mechanics earned him a place at Los Alamos working on the Manhattan Project under J. Robert Oppenheimer, where the giddy young man held his own among the nation’s greatest minds. There, Feynman turned theory into practice, culminating in the Trinity test, on July 16, 1945, when the Atomic Age was born. He was only twenty-seven. And he was just getting started. In this sweeping biography, James Gleick captures the forceful personality of a great man, integrating Feynman’s work and life in a way that is accessible to laymen and fascinating for the scientists who follow in his footsteps.

    His talents are vividly revealed in this exciting and penetrating explanation of how the central laws of physical science evolved — from Pythagoras' discovery of frequency ratios in the 6th century B.C. to today's research on elementary particles.Unlike many books on physics which focus entirely on fact and theory with little or no historic detail, the present work incorporates fascinating personal and biographical data about the great physicists of past and present. Thus Dr. Gamow discusses on an equal basis the trail of Galileo and the basic laws of mechanics which he discovered, or gives his personal recollections about Niels Bohr along with detailed discussion of Bohr's atomic model. You'll also find revealing glimpses of Newton, Huygens, Heisenberg, Pauli, Einstein, and many other immortals of science.Each chapter is centered around a single great figure, or at most two, with other physicists of the era and their contributions forming a background. Major topics include the dawn of physics, the Dark Ages and the Renaissance, Newtonian physics, heat as energy, electricity, the relativistic revolution, quantum theory, and the atomic nucleus and elementary particles.As Dr. Gamow points out in the Preface, the aim of this book is to give the reader the feeling of what physics is, and what kind of people physicists are. This delightfully informal approach, combined with the book's clear, easy-to-follow explanations, will especially appeal to young readers but will stimulate and entertain science enthusiasts of all ages. 1961 edition."The whole thing is a tour de force covering all the important landmarks." — Guardian

    Michael Guillen, known to millions as the science editor of ABC's Good Morning America, tells the fascinating stories behind five mathematical equations. As a regular contributor to daytime's most popular morning news show and an instructor at Harvard University, Dr. Michael Guillen has earned the respect of millions as a clear and entertaining guide to the exhilarating world of science and mathematics. Now Dr. Guillen unravels the equations that have led to the inventions and events that characterize the modern world, one of which -- Albert Einstein's famous energy equation, E=mc2 -- enabled the creation of the nuclear bomb. Also revealed are the mathematical foundations for the moon landing, airplane travel, the electric generator -- and even life itself. Praised by Publishers Weekly as "a wholly accessible, beautifully written exploration of the potent mathematical imagination," and named a Best Nonfiction Book of 1995, the stories behind The Five Equations That Changed the World, as told by Dr. Guillen, are not only chronicles of science, but also gripping dramas of jealousy, fame, war, and discovery. Dr. Michael Guillen is Instructor of Physics and Mathematics in the Core Curriculum Program at Harvard University.

    Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. More than that—mathematics has often made predictions, for example, about subatomic particles or cosmic phenomena that were unknown at the time, but later were proven to be true. Is mathematics ultimately invented or discovered? If, as Einstein insisted, mathematics is “a product of human thought that is independent of experience,” how can it so accurately describe and even predict the world around us? Physicist and author Mario Livio brilliantly explores mathematical ideas from Pythagoras to the present day as he shows us how intriguing questions and ingenious answers have led to ever deeper insights into our world. This fascinating book will interest anyone curious about the human mind, the scientific world, and the relationship between them.

    Accordingly, he once derided as "spooky action at a distance" the notion that two elementary particles far removed from each other could nonetheless influence each other's properties—a hypothetical phenomenon his fellow theorist Erwin Schrödinger termed "quantum entanglement."In a series of ingenious experiments conducted in various locations—from a dank sewage tunnel under the Danube River to the balmy air between a pair of mountain peaks in the Canary Islands—the author and his colleagues have demonstrated the reality of such entanglement using photons, or light quanta, created by laser beams. In principle the lessons learned may be applicable in other areas, including the eventual development of quantum computers.

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.

    Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon's Ring, the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

    Set in almost uninhabitable regions of Central Australia, The Songlines asks and tries to answer these questions: Why is man the most restless, dissatisfied of animals? Why do wandering people conceive the world as perfect whereas sedentary ones always try to change it? Why have the great teachers—Christ or the Buddha—recommended the Road as the way. to salvation? Do we agree with Pascal that all man's troubles stem from his inability to sit quietly in a room?We do not often ask these questions today for we commonly assume that living in a house is normal and that the wandering life is aberrant. But for more than twenty years Chatwin has mulled over the possibility that the reverse might be the case.Pre-colonial Australia was the last landmass on earth peopled not by herdsmen, farmers, or city dwellers, but by hunter-gatherers. Their labyrinths of invisible pathways across the continent are known to us as Songlines or Dreaming Tracks, but to the Aboriginals as the tracks of their ancestors—the Way of the Law. Along these "roads" they travel in order to perform all those activities that are distinctively human—song, dance, marriage, exchange of ideas, and arrangements of territorial boundaries by agreement rather than force.In Chatwin's search for the Songlines, Arkady is an ideal friend and guide: Australian by birth, the son of a Cossack exile, with all the strength and warmth of his inheritance. Whether hunting kangaroo from a Land Cruiser, talking to the diminutive Rolf in his book-crammed trailer, buying drinks for a bigoted policeman (and would-be writer), cheering as Arkady's true love declares herself (part of The Songlines is a romantic comedy), Chatwin turns this almost implausible picaresque adventure into something approaching the scale of a Greek tragedy.The life of the Aboriginals stands in vivid contrast, of course, to the prevailing cultures of our time. And The Songlines presents unforgettable details about the kinds of disputes we know all too well from less traumatic confrontations: over sacred lands invaded by railroads, mines, and construction sites, over the laws and rights of a poor people versus a wealthy invasive one. To Chatwin these are but recent, local examples of an eternal basic distinction between settlers and wanderers. His book, devoted to the latter, is a brilliant evocation of this profound optimism: that man is by nature not a bellicose aggressor but a pacific, song-creating, adaptive species whose destiny is to quest for the truth.
