For going on two decades, Scientific American's "Ask the Experts" column has been answering reader questions on all fields of science. We've taken your questions from the basic to the esoteric and reached out to top scientists, professors and researchers to find out why the sky is blue or how planets acquire rings. Now, we've combed through our archives and have compiled some of the most interesting questions (and answers) into a series of eBooks. Organized by subject, each eBook provides short, easily digestible answers to questions on that particular branch of the sciences. The Human Body and Mind is the third eBook in this series, and it tackles questions about our own strange and mysterious biology. [Note: Health and medicine will be covered in a separate eBook.] Our experts field queries on evolution, bodily quirks and psychological feats. Have you ever wondered why humans lost their body hair? Curious about what causes a hangover? Or what makes that popping sound when we crack our knuckles? What about the oft-cited maxim that we only use 10 percent of our brains? Professors, scientists and biologists provide answers that are at once accurate, understandable and sometimes just plain funny.

We’ve been led to believe that when we get sick, it’s our genetics. Or it’s just bad luck—and doctors alone hold the keys to optimal health. For years, Lissa Rankin, M.D., believed the same. But when her own health started to suffer, and she turned to Western medical treatments, she found that they not only failed to help; they made her worse. So she decided to take matters into her own hands. Through her research, Dr. Rankin discovered that the health care she had been taught to practice was missing something crucial: a recognition of the body’s innate ability to self-repair and an appreciation for how we can control these self-healing mechanisms with the power of the mind. In an attempt to better understand this phenomenon, she explored peer-reviewed medical literature and found evidence that the medical establishment had been proving that the body can heal itself for over 50 years. Using extraordinary cases of spontaneous healing, Dr. Rankin shows how thoughts, feelings, and beliefs can alter the body’s physiology. She lays out the scientific data proving that loneliness, pessimism, depression, fear, and anxiety damage the body, while intimate relationships, gratitude, meditation, sex, and authentic self-expression flip on the body’s self-healing processes. In the final section of the book, you’ll be introduced to a radical new wellness model based on Dr. Rankin’s scientific findings. Her unique six-step program will help you uncover where things might be out of whack in your life—spiritually, creatively, environmentally, nutritionally, and in your professional and personal relationships—so that you can create a customized treatment plan aimed at bolstering these health-promoting pieces of your life. You’ll learn how to listen to your body’s "whispers" before they turn to life-threatening "screams" that can be prevented with proper self-care, and you’ll learn how to trust your inner guidance when making decisions about your health and your life. By the time you finish Mind Over Medicine, you’ll have made your own Diagnosis, written your own Prescription, and created a clear action plan designed to help you make your body ripe for miracles.

This is not a conventional book. It is designed to stimulate and challenge all people who are curious to find out about the world they inhabit and their place within it. It does this by suggesting questions and lines of questioning on a wide range of topics. The book does not provide answers or model arguments but prompts people to create their own questions and a reading log or journal. To this end, almost all questions have a list of books or articles to provide a starter for stimulating further reading. Once you start, you will be hooked! Never stop questioning.

First released in the Spring of 1999, How People Learn has been expanded to show how the theories and insights from the original book can translate into actions and practice, now making a real connection between classroom activities and learning behavior. This edition includes far-reaching suggestions for research that could increase the impact that classroom teaching has on actual learning. Like the original edition, this book offers exciting new research about the mind and the brain that provides answers to a number of compelling questions. When do infants begin to learn? How do experts learn and how is this different from non-experts? What can teachers and schools do-with curricula, classroom settings, and teaching methodsâ€"to help children learn most effectively? New evidence from many branches of science has significantly added to our understanding of what it means to know, from the neural processes that occur during learning to the influence of culture on what people see and absorb. How People Learn examines these findings and their implications for what we teach, how we teach it, and how we assess what our children learn. The book uses exemplary teaching to illustrate how approaches based on what we now know result in in-depth learning. This new knowledge calls into question concepts and practices firmly entrenched in our current education system. Topics include: How learning actually changes the physical structure of the brain. How existing knowledge affects what people notice and how they learn. What the thought processes of experts tell us about how to teach. The amazing learning potential of infants. The relationship of classroom learning and everyday settings of community and workplace. Learning needs and opportunities for teachers. A realistic look at the role of technology in education.

"Takes you inside the amazing science of how the body affects the mind, and shows how to use that wisdom to live smarter and maximize what your body teaches your mind"--

Essential reading for anyone seeking to understand their own mind and to find a spiritual path that is compatible with science As an impressionable young student, Susan Blackmore had an intense, dramatic and life-changing experience, seeming to leave her body and travel the world. With no rational explanation for her out-of-body experience (OBE) she turned to astral projection and the paranormal, but soon despaired of finding answers. Decades later, a Swiss neurosurgeon accidentally discovered the spot in the brain that can induce OBEs and everything changed; this crucial spot is part of the brain's self-system and when disturbed so is our experience of self. Blackmore leaped back into OBE research and at last began to unravel what had happened to her. Seeing Myself describes her long quest for answers through spirituality, religion, drugs, meditation, philosophy and neuroscience. Anyone can have an OBE, indeed 15 per cent of us have. Even more have experienced sleep paralysis, lucid dreaming and the creepy sense of an invisible presence. At last, with the advent of brain stimulation, fMRI scanning and virtual reality, all these phenomena are beginning to make sense. Long relegated to the very fringes of research, the new science of out-of-body experiences is now contributing to our understanding of consciousness and our very selves.
