    Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. For the first time, Rise of the Rocket Girls tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science. Based on extensive research and interviews with all the living members of the team, Rise of the Rocket Girls offers a unique perspective on the role of women in science: both where we've been, and the far reaches of space to which we're heading.

    The work of English clergyman, educator and Shakespearean scholar Edwin A. Abbott (1838-1926), it describes the journeys of A. Square [sic – ed.], a mathematician and resident of the two-dimensional Flatland, where women-thin, straight lines-are the lowliest of shapes, and where men may have any number of sides, depending on their social status.Through strange occurrences that bring him into contact with a host of geometric forms, Square has adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions) and ultimately entertains thoughts of visiting a land of four dimensions—a revolutionary idea for which he is returned to his two-dimensional world. Charmingly illustrated by the author, Flatland is not only fascinating reading, it is still a first-rate fictional introduction to the concept of the multiple dimensions of space. "Instructive, entertaining, and stimulating to the imagination." — Mathematics Teacher.

    Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress.As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear--and the ones that plague us now--are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way--through fighting or fleeing. Over time, this activation of a stress response makes us sick.

    Beginning with the primordial sounds of nature, we have experienced an ever-increasing complexity of our sonic surroundings. As civilization develops, new noises rise up around us: from the creaking wheel, the clang of the blacksmith’s hammer, and the distant chugging of steam trains to the “sound imperialism” of airports, city streets, and factories. The author contends that we now suffer from an overabundance of acoustic information and a proportionate diminishing of our ability to hear the nuances and subtleties of sound. Our task, he maintains, is to listen, analyze, and make distinctions. As a society we have become more aware of the toxic wastes that can enter our bodies through the air we breathe and the water we drink. In fact, the pollution of our sonic environment is no less real. Schafer emphasizes the importance of discerning the sounds that enrich and feed us and using them to create healthier environments. To this end, he explains how to classify sounds, appreciating their beauty or ugliness, and provides exercises and “soundwalks” to help us become more discriminating and sensitive to the sounds around us. This book is a pioneering exploration of our acoustic environment, past and present, and an attempt to imagine what it might become in the future.

    Yet in The Science of Interstellar, Kip Thorne, the physicist who assisted Nolan on the scientific aspects of Interstellar, shows us that the movie’s jaw-dropping events and stunning, never-before-attempted visuals are grounded in real science. Thorne shares his experiences working as the science adviser on the film and then moves on to the science itself. In chapters on wormholes, black holes, interstellar travel, and much more, Thorne’s scientific insights—many of them triggered during the actual scripting and shooting of Interstellar—describe the physical laws that govern our universe and the truly astounding phenomena that those laws make possible.Interstellar and all related characters and elements are trademarks of and © Warner Bros.

    Bonnie Henry has been called one of the most effective public health figures in the world by The New York Times. She has been called a calming voice in a sea of coronavirus madness, and our hero in national newspapers. But in the waning days of 2019, when the first rumours of a strange respiratory ailment in Wuhan, China began to trickle into her office in British Colombia, these accolades lay in a barely imaginable future.Only weeks later, the whole world would look back on the previous year with the kind of nostalgia usually reserved for the distant past. With a staggering suddenness, our livelihoods, our closest relationships, our habits and our homes had all been transformed.In a moment when half-truths threatened to drown out the truth, when recklessness all too often exposed those around us to very real danger, and when it was difficult to tell paranoia from healthy respect for an invisible threat, Dr. Henry's transparency, humility, and humanity became a beacon for millions of Canadians.And her trademark enjoinder to be kind, be calm, and be safe became words for us all to live by.Coincidentally, Dr. Henry's sister, Lynn, arrived in BC for a long-planned visit on March 12, just as the virus revealed itself as a pandemic. For the four ensuing weeks, Lynn had rare insight into the whirlwind of Bonnie's daily life, with its moments of agony and gravity as well as its occasional episodes of levity and grace. Both a global story and a family story, Be Kind, Be Calm, Be Safe combines Lynn's observations and knowledge of Bonnie's personal and professional background with Bonnie's recollections of how and why decisions were made, to tell in a vivid way the dramatic tale of the four weeks that changed all our lives.Be Kind, Be Calm, Be Safe is about communication, leadership, and public trust; about the balance between politics and policy; and, at heart, about what and who we value, as individuals and a society.The authors' advance from the publisher will be donated to charities with a focus on alleviating communities hit particularly hard by the pandemic: True North Aid with its Covid-19 response in Northern Indigenous communities, and First Book Canada, with its focus on reading and literacy for underserved, marginalized youth.

    Through metaphors and straightforward language, it breathes life into astrophysics, unveiling how particles and forces and fields interplay to create the drama in the heavens above us.

    Is it in our genes? The structure of our brains? Our genome may determine our eye color and even aspects of our personality. But our friendships, failures, and passions also shape who we are. The question is: how?Sebastian Seung, a dynamic professor at MIT, is on a quest to discover the biological basis of identity. He believes it lies in the pattern of connections between the brain’s neurons, which change slowly over time as we learn and grow. The connectome, as it’s called, is where our genetic inheritance intersects with our life experience. It’s where nature meets nurture.Seung introduces us to the dedicated researchers who are mapping the brain’s connections, neuron by neuron, synapse by synapse. It is a monumental undertaking—the scientific equivalent of climbing Mount Everest—but if they succeed, it could reveal the basis of personality, intelligence, memory, and perhaps even mental disorders. Many scientists speculate that people with anorexia, autism, and schizophrenia are "wired differently," but nobody knows for sure. The brain’s wiring has never been clearly seen.In sparklingly clear prose, Seung reveals the amazing technological advances that will soon help us map connectomes. He also examines the evidence that these maps will someday allow humans to "upload" their minds into computers, achieving a kind of immortality.Connectome is a mind-bending adventure story, told with great passion and authority. It presents a daring scientific and technological vision for at last understanding what makes us who we are. Welcome to the future of neuroscience.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    Yet recent research indicates that experiences in nature are essential for healthy growth. Regular exposure to nature can help relieve stress, depression, and attention deficits. It can reduce bullying, combat illness, and boost academic scores. Most critical of all, abundant time in nature seems to yield long-term benefits in kids’ cognitive, emotional, and social development. Yet teachers, parents, and other caregivers lack a basic understanding of how to engender a meaningful, lasting connection between children and the natural world. How to Raise a Wild Child offers a timely and engaging antidote, showing how kids’ connection to nature changes as they mature. Distilling the latest research in multiple disciplines, Sampson reveals how adults can help kids fall in love with nature—enlisting technology as an ally, taking advantage of urban nature, and instilling a sense of place along the way.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    She was married with children and a good career. So why did she feel miserable? And why did it seem that other Generation X women were miserable, too?Calhoun decided to find some answers. She looked into housing costs, HR trends, credit card debt averages, and divorce data. At every turn, she saw a pattern: sandwiched between the Boomers and the Millennials, Gen X women were facing new problems as they entered middle age, problems that were being largely overlooked.Speaking with women across America about their experiences as the generation raised to “have it all,” Calhoun found that most were exhausted, terrified about money, under-employed, and overwhelmed. Instead of being heard, they were told instead to lean in, take “me-time,” or make a chore chart to get their lives and homes in order.In Why We Can’t Sleep, Calhoun opens up the cultural and political contexts of Gen X’s predicament and offers solutions for how to pull oneself out of the abyss—and keep the next generation of women from falling in. The result is reassuring, empowering, and essential reading for all middle-aged women, and anyone who hopes to understand them.

    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history? What does driving a sports car have to do with Steven Weinberg’s quest for the “theory of everything”? Physicist and journalist Stefan Klein’s intimate conversations with nineteen of the world’s best-known scientists (including three Nobel Laureates) let us listen in as they talk about their paradigm-changing work—and how it is deeply rooted in their daily lives. • Cosmologist Martin Rees on the beginning and end of the world • Evolutionary biologist Richard Dawkins on egoism and selflessness • Neuroscientist V. S. Ramachandran on consciousness • Molecular biologist Elizabeth Blackburn on aging • Philosopher Peter Singer on morality • Physician and social scientist Nicholas Christakis on human relationships • Biochemist Craig Venter on the human genome • Chemist and poet Roald Hoffmann on beauty
