The presentation develops physical insight by stressing the microscopic content of the theory.

    A realistic guide to becoming an Astronaut at a young age.

    David Peat argue that science has lost its way in recent years and needs to go beyond a narrow and fragmented view of nature and embrace a wider holistic view that restores the importance of creativity and communication for all humanity - not just scientists. The result of a close collaboration by one of the 20th century's greatest physicists and thinkers, David Bohm, with leading science writer F. David Peat, provides a rare combination of profound reflection and clear exposition that can be appreciated by anyone concerned with science and its importance in our lives. This new edition includes a new preface and an extended additional chapter by Peat which draws upon further discussions with David Bohm before the latter's death in 1992. A fascinating diagnosis and considered proposal for a cure for science's ills, it is also very accessible entry point to the work of David Bohm. Bohm and Peat contend that science has lost its bearings in the last century in favour of a narrow, abstracted, fragmented approach to nature and reality. Tracing the history of science, Bohm and Peat offer intriguing new insights into how scientific theories come into being, how to eliminate blocks of creativity and how science can lead to a deeper understanding of society, the human condition and the human mind itself.

    

    But far more fundamentally, we live in a universe made of quanta. Many things are not made of atoms: light, radio waves, electric current, magnetic fields, Earth's gravitational field, not to mention exotica such a neutron stars, black holes, dark energy, and dark matter. But everything, including atoms, is made of highly unified or "coherent" bundles of energy called "quanta" that (like everything else) obey certain rules. In the case of the quantum, these rules are called "quantum physics." This is a book about quanta and their unexpected, some would say peculiar, behavior--tales, if you will, of the quantum.The quantum has developed the reputation of being capricious, bewildering, even impossible to understand. The peculiar habits of quanta are certainly not what we would have expected to find at the foundation of physical reality, but these habits are not necessarily bewildering and not at all impossible or paradoxical. This book explains those habits--the quantum rules--in everyday language, without mathematics or unnecessary technicalities. While most popular books about quantum physics follow the topic's scientific history from 1900 to today, this book follows the phenomena: wave-particle duality, fundamental randomness, quantum states, superpositions (being in two places at once), entanglement, non-locality, Schrodinger's cat, and quantum jumps, and presents the history and the scientists only to the extent that they illuminate the phenomena.

    A wealth of accompanying figures and exercises illustrate and develop the material in more depth. They describe what a quantum computer is, how it can be used to solve problems faster than familiar "classical" computers, and the real-world implementation of quantum computers. Their book concludes with an explanation of how quantum states can be used to perform remarkable feats of communication, and of how it is possible to protect quantum states against the effects of noise.

    It illustrates both the cohesiveness of the relatively few fundamental ideas in this area and the great variety of problems these ideas solve. All of the problems address principles and procedures inherent in the design and anlysis of engineering structures and mechanical systems, with many of the problems referring explicitly to design considerations.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    From what quantum physics can do for the world to understanding hydrogen atoms, readers will get complete coverage of the subject, along with numerous examples to help them tackle the tough equations. Compatible with classroom text books and courses, Quantum Physics For Dummies lets students study at their own paces and helps them prepare for graduate or professional exams. Coverage includes: The Schrodinger Equation and its Applications The Foundations of Quantum Physics Vector Notation Spin Scattering Theory, Angular Momentum, and more

    But what sort of person was the young Albert Einstein, before he became universally acclaimed as the archetypal genius? And how did his genius unfold? In this brilliant new Kindle Single, scientist Robyn Arianrhod blends biography with popular science to tell the story of how young Albert developed a theory that – unknown to him at first – contained the seeds of his extraordinary equation E = mc2. Arianrhod, who wrote her PhD on Einstein’s general theory of relativity, makes the ideas behind the equation accessible to the lay reader, and sets young Einstein’s exploration of these ideas against the backdrop of his first loves, his family and marriage, and, above all, his childlike wonder at the nature of the universe. She introduces his heroes and scientific inspirations, and the friends who believed in him when no one else did. In personalising Einstein, she brings to life both the man and his science, in a short, easy-to-read narrative. In showing how he discovered his famous equation, and what it means, she draws a compelling portrait of this prodigious intellect whose unfathomable grasp of the building blocks of physics would change our world forever. About the Author: Dr Robyn Arianrhod is the author of two critically acclaimed works of popular science and scientific history: Einstein’s Heroes: Imagining the World Through the Language of Mathematics, and Seduced by Logic: Émilie du Châtelet, Mary Somerville and the Newtonian Revolution. Both were shortlisted for major book awards and are published in the USA. Einstein’s Heroes was translated into several languages. Robyn was awarded her PhD for research on Einstein’s general theory of relativity and has lectured in applied mathematics (including special relativity) for many years. She is currently an Adjunct Research Fellow in the School of Mathematical Sciences at Monash University in Melbourne, where she is undertaking research on the structure of relativistic space-times. She is also a technical reviewer for the American Mathematical Society.

    Newborn babies typically wake every two to three hours, and there’s nothing bleary-eyed, exhausted parents want more than a night of uninterrupted sleep. But while there’s plenty of advice out there, there is nothing that’s based on the latest cutting-edge research about sleep—until now. In How Babies Sleep, Sofia Axelrod, PhD—neuroscientist, sleep consultant, and mother of two—introduces the first baby sleep method that is truly rooted in the science of sleep. After having her first child, Axelrod realized that the typical baby sleep advice conflicted with the actual science of sleep, inlcuding the findings from her mentor’s Nobel Prize–winning sleep lab. She developed her transformative method based on the latest discoveries about our body’s circadian clock and how it is disturbed by light and other external stimuli. After seeing incredible results with her own babies, she has since counseled countless families in her groundbreaking method—which works with babies’ needs and helps little ones learn to self-soothe, fall asleep more easily, and stay asleep through the night. You’ll discover helpful tips that work, and learn: why using a red lightbulb (instead of a regular one) in the nursery at night can minimize wakings; why the age-old advice “don’t wake a sleeping baby” isn’t true; how to create a healthy routine; how to sleep train gently with minimal crying (under two minutes); and so much more in this revolutionary and effective book that will help both you and your baby enjoy a peaceful night’s sleep.
