Book Description
The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself--and continues to almost two hundred years later. Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment. Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe. How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit? With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.

Book Description
This book describes the most complex machine ever sent to another planet: Curiosity. It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

Book Description
The New York Times bestseller that gives readers a paradigm-shattering new way to think about motivation from the author of When: The Scientific Secrets of Perfect Timing Most people believe that the best way to motivate is with rewards like money—the carrot-and-stick approach. That's a mistake, says Daniel H. Pink (author of To Sell Is Human: The Surprising Truth About Motivating Others). In this provocative and persuasive new book, he asserts that the secret to high performance and satisfaction-at work, at school, and at home—is the deeply human need to direct our own lives, to learn and create new things, and to do better by ourselves and our world. Drawing on four decades of scientific research on human motivation, Pink exposes the mismatch between what science knows and what business does—and how that affects every aspect of life. He examines the three elements of true motivation—autonomy, mastery, and purpose-and offers smart and surprising techniques for putting these into action in a unique book that will change how we think and transform how we live.

Book Description
Quantum mechanics is an extraordinarily successful scientific theory. It is also completely mad. Although the theory quite obviously works, it leaves us chasing ghosts and phantoms; particles that are waves and waves that are particles; cats that are at once both alive and dead; and lots of seemingly spooky goings-on. But if we're prepared to be a little more specific about what we mean when we talk about 'reality' and a little more circumspect in the way we think a scientific theory might represent such a reality, then all the mystery goes away. This shows that the choice we face is actually a philosophical one. Here, Jim Baggott provides a quick but comprehensive introduction to quantum mechanics for the general reader, and explains what makes this theory so very different from the rest. He also explores the processes involved in developing scientific theories and explains how these lead to different philosophical positions, essential if we are to understand the nature of the great debate between Niels Bohr and Albert Einstein. Moving forwards, Baggott then provides a comprehensive guide to attempts to determine what the theory actually means, from the Copenhagen interpretation to many worlds and the multiverse. Richard Feynman once declared that 'nobody understands quantum mechanics'. This book will tell you why.

Book Description
In the tradition of Oliver Sacks, science journalist Anil Ananthaswamy skillfully inspects the bewildering connections among brain, body, mind, self, and society by examining a range of neuropsychological ailments from autism and Alzheimer’s to out-of-body experiences and body integrity identity disorder Award-winning science writer Anil Ananthaswamy smartly explores the concept of self by way of several mental conditions that eat away at patients’ identities, showing we learn a lot about being human from people with a fragmented or altered sense of self. Ananthaswamy travelled the world to meet those who suffer from “maladies of the self” interviewing patients, psychiatrists, philosophers and neuroscientists along the way. He charts how the self is affected by Asperger’s, autism, Alzheimer’s, epilepsy, schizophrenia, among many other mental conditions, revealing how the brain constructs our sense of self. Each chapter is anchored with stories of people who experience themselves differently from the norm. Readers meet individuals in various stages of Alzheimer’s disease where the loss of memory and cognition results in the loss of some aspects of the self. We meet a woman who recalls the feeling of her first major encounter with schizophrenia which she describes as an outside force controlling her. Ananthaswamy also looks at several less­ familiar conditions, such as Cotard’s syndrome, in which patients believe they are dead, and those with body integrity identity disorder, where the patient seeks to have a body part amputated because it “doesn’t belong to them.” Moving nimbly back and forth from the individual stories to scientific analysis The Man Who Wasn’t There is a wholly original exploration of the human self which raises fascinating questions about the mind-body connection.

Book Description
From the award-winning author of The Gentleman’s Daughter,a witty and academic illumination of daily domestic life in Georgian England. In this brilliant work, Amanda Vickery unlocks the homes of Georgian England to examine the lives of the people who lived there. Writing with her customary wit and verve, she introduces us to men and women from all walks of life: gentlewoman Anne Dormer in her stately Oxfordshire mansion, bachelor clerk and future novelist Anthony Trollope in his dreary London lodgings, genteel spinsters keeping up appearances in two rooms with yellow wallpaper, servants with only a locking box to call their own. Vickery makes ingenious use of upholsterer’s ledgers, burglary trials, and other unusual sources to reveal the roles of house and home in economic survival, social success, and political representation during the long eighteenth century. Through the spread of formal visiting, the proliferation of affordable ornamental furnishings, the commercial celebration of feminine artistry at home, and the currency of the language of taste, even modest homes turned into arenas of social campaign and exhibition. The basis of a 3-part TV series for BBC2. “Vickery is that rare thing, an…historian who writes like a novelist.”—Jane Schilling, Daily Mail “Comparison between Vickery and Jane Austen is irresistible…This book is almost too pleasurable, in that Vickery's style and delicious nosiness conceal some seriously weighty scholarship.”—Lisa Hilton, The Independent “If until now the Georgian home has been like a monochrome engraving, Vickery has made it three dimensional and vibrantly colored. Behind Closed Doors demonstrates that rigorous academic work can also be nosy, gossipy, and utterly engaging.”—Andrea Wulf, New York Times Book Review

Book Description
A daring new vision of the quantum universe, and the scandals controversies, and questions that may illuminate our future--from Canada's leading mind on contemporary physics. Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schrödinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.
