Amir Aczel, critically acclaimed author of Fermat's Last Theorem, takes us into the heart of science's greatest mystery. In January 1998, astronomers found evidence that the cosmos is expanding at an ever-increasing rate. The way we perceive the universe was changed forever. The most compelling theory cosmologists could find to explain this phenomenon was Einstein's cosmological constant, a theory he conceived--and rejected---over eighty years ago. Drawing on newly discovered letters of Einstein--many translated here for the first time--years of research, and interviews with prominent mathematicians, cosmologists, physicists, and astronomers, Aczel takes us on a fascinating journey into "the strange geometry of space-time," and into the mind of a genius. Here the unthinkable becomes real: an infinite, ever-expanding, ever-accelerating universe whose only absolute is the speed of light. Awesome in scope, thrilling in detail, God's Equation is storytelling at its finest.

    Beautifully illustrated with old engravings as well as contemporary imagery, Sacred Number introduces basic counting systems; significant numbers from major religious texts; the importance of astronomy, geometry, and music to number quality; how numbers affect architecture. Lundy explains why the ideas of Pythagoras still resonate, and she profiles each number from one to ten to show its distinct qualities: why, for example, the golden section is associated with five, and seven with the Virgin Mary.

    It offers a bold new way of thinking about and responding to the personal and strategic challenges everyone in business faces these days.

    This concept is at the root of the computational worldview, which basically says that very complex systems — the world we live in — have their beginnings in simple mathematical equations. We've lately come to understand that such an algorithm is only the start of a never-ending story — the real action occurs in the unfolding consequences of the rules. The chip-in-a-box computers so popular in our time have acted as a kind of microscope, letting us see into the secret machinery of the world. In Lifebox, Rucker uses whimsical drawings, fables, and humor to demonstrate that everything is a computation — that thoughts, computations, and physical processes are all the same. Rucker discusses the linguistic and computational advances that make this kind of "digital philosophy" possible, and explains how, like every great new principle, the computational world view contains the seeds of a next step.

    It is rich in narrative, anecdote, attention to human detail, and stories of competition among scientists who have dominated the field.

    Accordingly, he once derided as "spooky action at a distance" the notion that two elementary particles far removed from each other could nonetheless influence each other's properties—a hypothetical phenomenon his fellow theorist Erwin Schrödinger termed "quantum entanglement."In a series of ingenious experiments conducted in various locations—from a dank sewage tunnel under the Danube River to the balmy air between a pair of mountain peaks in the Canary Islands—the author and his colleagues have demonstrated the reality of such entanglement using photons, or light quanta, created by laser beams. In principle the lessons learned may be applicable in other areas, including the eventual development of quantum computers.

    Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    Provides a review of introductory noncalculus-based physics for those who do not have a strong background in mathematics.

    One of the simplest—and the best—was suggested by the philosopher John Campbell: “Thinking in slow motion.” But, for most people, slow motion is only appealing in small doses. A whole movie in slow-mo would be one for the art gallery, not the multiplex. This is the problem that faces those who want to write about philosophy for a broad readership: a certain amount of fast-forward is needed, but if you go too fast you’ll stop doing philosophy altogether.John D Caputo’s entertaining investigation into the nature of truth gets the balance right. His project is to show how postmodernism can help us think through contemporary debates about religion, relativism and the legacy of the Enlightenment. Rather than dividing the world into strict categories such as the rational and irrational, Caputo’s postmodern approach tries to widen our understanding of truth. He is not a naive relativist, however. “I am not arguing against the truth of propositions,” he says. “I am arguing that truth cannot be confined to propositions.” This means taking seriously the truths one encounters in novels, say, as well as religious narratives.As this last idea suggests, there is plenty in Truth to annoy Richard Dawkins, as well as many contemporary analytic philosophers—but the book is better off for its boldness. Rather than pre-empting every counter-attack, Caputo sets out his case confidently, enlisting Nietzsche, Kierkegaard and Derrida as his allies. (His explanation of Derrida’s thought is one of the clearest that I’ve read.) This book does not claim to be the final word on truth—indeed Caputo believes the quest for an ultimate and unchanging definition of truth is doomed to failure—but it might be the starting point for a more sophisticated discussion.

    And through his live gatherings and radio talks, Alan Watts was at the forefront—igniting astonishing insights into who we are and where we're heading. Based on a legendary series of seminars, Just So illuminates three fascinating domains: money versus real wealth, the spirituality of a deeper materialism, and how technology and spirituality are both guiding us to ever greater interconnection in the universe that we find ourselves in. Along the way, readers will explore many other themes, at turns humorous, prescient, and more relevant today than ever. What unfolds is a liberating view of humanity that arises from possibility and the unpredictable—perfect and “just so,” not in spite of its messy imperfections, but because of them.Book highlights:1.

    It features all the great names in science, including Pythagoras, Galileo, Newton, Darwin, and Einstein, as well as more recent contributors such as Rachel Carson, James Lovelock, and Stephen Hawking.This little book presents serious science simply, answering questions like:What is Pythagorean Theorem? What is the difference between circadian rhythms and the popular concept of biorhythms? What is Hawking’s Black Hole Theory? Who developed the World Wide Web?

    First published in 1937.

    Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

    This work has played a major role in the development of our current understanding of the profound nature of quantum concepts and of the fundamental limitations they impose on the applicability of the classical ideas of space, time and locality. This book contains all of John Bell's published and unpublished papers on the conceptual and philosophical problems of quantum mechanics.
