Russell's classic The Principles of Mathematics sets forth his landmark thesis that mathematics and logic are identical―that what is commonly called mathematics is simply later deductions from logical premises.His ideas have had a profound influence on twentieth-century work on logic and the foundations of mathematics.

    Although it presents the main ideas of quantum theory essentially in nonmathematical terms, it follows these with a broad range of specific applications that are worked out in considerable mathematical detail. Addressed primarily to advanced undergraduate students, the text begins with a study of the physical formulation of the quantum theory, from its origin and early development through an analysis of wave vs. particle properties of matter. In Part II, Professor Bohm addresses the mathematical formulation of the quantum theory, examining wave functions, operators, Schrödinger's equation, fluctuations, correlations, and eigenfunctions.Part III takes up applications to simple systems and further extensions of quantum theory formulation, including matrix formulation and spin and angular momentum. Parts IV and V explore the methods of approximate solution of Schrödinger's equation and the theory of scattering. In Part VI, the process of measurement is examined along with the relationship between quantum and classical concepts.Throughout the text, Professor Bohm places strong emphasis on showing how the quantum theory can be developed in a natural way, starting from the previously existing classical theory and going step by step through the experimental facts and theoretical lines of reasoning which led to replacement of the classical theory by the quantum theory.

    In Evolution Impossible, Dr. John Ashton uses discoveries in genetics, biochemistry, geology, radiometric dating, and other scientific disciplines to explain why the theory of evolution is a myth. Regardless of your level of scientific education, you will finish this book able to cite 12 reasons why evolution cannot explain the origin of life.

    Yet today there is only one—homo sapiens. What happened to the others? And what may happen to us?In this first volume of the full-color illustrated adaptation of his groundbreaking book, renowned historian Yuval Harari tells the story of humankind’s creation and evolution, exploring the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human.” From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens challenges us to reconsider accepted beliefs, connect past developments with contemporary concerns, and view specific events within the context of larger ideas. Featuring 256 pages of full-color illustrations and easy-to-understand text covering the first part of the full-length original edition, this adaptation of the mind-expanding book furthers the ongoing conversation as it introduces Harari’s ideas to a wide new readership.

    For thousands of years, holy books have told us that such a life is available only through obedience and submission to some higher power. Today, the faithful keep popular devotionals and tracts within easy reach on bedside tables and mobile devices, all communicating this common message: “Life is meaningless without God.” In this volume, former pastor Dan Barker eloquently, powerfully, and rationally upends this long-held belief. Offering words of enrichment, emancipation, and inspiration, he reminds us how millions of atheists lead happy, loving, moral, and purpose-filled lives. Practicing what he preaches, he also demonstrates through his own personal journey that life is valuable for its own sake—that meaning and purpose come not from above, but from within.

    This work is the result of those requests. It is full of controversial claims, so be warned. I truly believe that if people follow the handful of principles in this short read, they will improve their health and change their lives.

    How can today's computers perform such a bewildering variety of tasks if computing is just glorified arithmetic? The answer, as Martin Davis lucidly illustrates, lies in the fact that computers are essentially engines of logic. Their hardware and software embody concepts developed over centuries by logicians such as Leibniz, Boole, and Godel, culminating in the amazing insights of Alan Turing. The Universal Computer traces the development of these concepts by exploring with captivating detail the lives and work of the geniuses who first formulated them. Readers will come away with a revelatory understanding of how and why computers work and how the algorithms within them came to be.

    An unsettling look at the Sconce family from the acclaimed true crime author of Deadly Lessons.   For sixty years, families in Southern California trusted the Sconce Family Funeral Home with their loved ones’ remains. That trust was betrayed in an extraordinary, horrifying fashion, as it was discovered that the family, seeing an opportunity, had been stealing gold fillings and harvesting the organs of the newly deceased, hiding the evidence by burning the bodies in their crematorium.   When the shocking acts came to light, a trial brought every gruesome detail to the forefront, and Ken Englade has—with even-handed, clear-eyed reporting—chronicled every chilling detail.

    It’s a combination of what you love, what the world needs, what you do best, and—yes—what you can be paid for. That’s ikigai: your true purpose. With the help of this beautiful little book, you can find your ikigai . . . and discover the secret to a long, happy, mindful, and meaningful life.

    G. Wells predicted that statistical thinking would be as necessary for citizenship in a technological world as the ability to read and write. But in the twenty-first century, we are often overwhelmed by a baffling array of percentages and probabilities as we try to navigate in a world dominated by statistics. Cognitive scientist Gerd Gigerenzer says that because we haven't learned statistical thinking, we don't understand risk and uncertainty. In order to assess risk -- everything from the risk of an automobile accident to the certainty or uncertainty of some common medical screening tests -- we need a basic understanding of statistics.Astonishingly, doctors and lawyers don't understand risk any better than anyone else. Gigerenzer reports a study in which doctors were told the results of breast cancer screenings and then were asked to explain the risks of contracting breast cancer to a woman who received a positive result from a screening. The actual risk was small because the test gives many false positives. But nearly every physician in the study overstated the risk. Yet many people will have to make important health decisions based on such information and the interpretation of that information by their doctors.Gigerenzer explains that a major obstacle to our understanding of numbers is that we live with an illusion of certainty. Many of us believe that HIV tests, DNA fingerprinting, and the growing number of genetic tests are absolutely certain. But even DNA evidence can produce spurious matches. We cling to our illusion of certainty because the medical industry, insurance companies, investment advisers, and election campaigns have become purveyors of certainty, marketing it like a commodity.To avoid confusion, says Gigerenzer, we should rely on more understandable representations of risk, such as absolute risks. For example, it is said that a mammography screening reduces the risk of breast cancer by 25 percent. But in absolute risks, that means that out of every 1,000 women who do not participate in screening, 4 will die; while out of 1,000 women who do, 3 will die. A 25 percent risk reduction sounds much more significant than a benefit that 1 out of 1,000 women will reap.This eye-opening book explains how we can overcome our ignorance of numbers and better understand the risks we may be taking with our money, our health, and our lives.

    Before the Internet, historical and doctrinal questions not addressed in LDS Church curriculum were mostly found in the scholarly articles of academic journals. This is no longer the case. These topics are now widely debated and discussed online and in other forums. And when members of the LDS Church come across information that is unfamiliar, they may feel surprise, fear, betrayal, or even anger. Laura Harris Hales has assembled a group of respected LDS scholars to offer help in A Reason for Faith: Navigating LDS Doctrine and Church History. Together these authors have spent an average of 25 years researching these topics. Their depth of knowledge and faith enables them to share reliable details, perspective, and context to both LDS doctrine and Church history. The information in these essays can begin an exciting process of discovery for readers as they learn from a source they can trust. Each chapter is engaging and thought-provoking, providing an invaluable resource for both the merely curious and the seriously concerned.

    We start counting our fingers and toes and end up balancing checkbooks and calculating risk. So powerful is the appeal of numbers that many people ascribe to them a mystical significance. Other numbers go beyond the supernatural, working to explain our universe and how it behaves. In Cosmic Numbers, mathematics professor James D. Stein traces the discovery, evolution, and interrelationships of the numbers that define our world. Everyone knows about the speed of light and absolute zero, but numbers like Boltzmann’s constant and the Chandrasekhar limit are not as well known, and they do far more than one might imagine: They tell us how this world began and what the future holds. Much more than a gee-whiz collection of facts and figures, Cosmic Numbers illuminates why particular numbers are so important—both to the scientist and to the rest of us.

    “They are both brilliantly original and outsiders,” the narrator tells us. “They are both besotted with mathematics. But for all their devotion, mathematics is indifferent, unaltered by any of their dramas . . . Against indifference, I want to tell their stories.” Which she does in a haunting, incantatory voice, the two lives unfolding in parallel narratives that overlap in the magnitude of each man’s achievement and demise: Gödel, delusional and paranoid, would starve himself to death; Turing, arrested for homosexual activities, would be driven to suicide. And they meet as well in the narrator’s mind, where facts are interwoven with her desire and determination to find meaning in the maze of their stories: two men devoted to truth of the highest abstract nature, yet unable to grasp the mundane truths of their own lives.A unique amalgam of luminous imagination and richly evoked historic character and event—A Madman Dreams of Turing Machines is a story about the pursuit of truth and its effect on the lives of two men. A story of genius and madness, incredible yet true.
