It offers a fascinating analysis of the works of Copernicus, Kepler, Galileo, Descartes, Hobbes, Gilbert, Boyle and Newton.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

    Much of the book takes the form of a discussion between a teacher and his students. They propose various solutions to some mathematical problems and investigate the strengths and weaknesses of these solutions. Their discussion (which mirrors certain real developments in the history of mathematics) raises some philosophical problems and some problems about the nature of mathematical discovery or creativity. Imre Lakatos is concerned throughout to combat the classical picture of mathematical development as a steady accumulation of established truths. He shows that mathematics grows instead through a richer, more dramatic process of the successive improvement of creative hypotheses by attempts to 'prove' them and by criticism of these attempts: the logic of proofs and refutations.

    Conscious Robots challenges us to face up to the reality of being human: just because we're conscious doesn't mean we're not robots. So what would we do with free will if we really had it? And how does “being a robot” explain why life, as Buddha suggested, is “inherently unsatisfactory”, despite our luxurious homes, successful careers and loving families? Conscious Robots shows why we’re so convinced that we’re in charge, when we’re really just carrying out our evolved pre-programmed instructions. And reveals the inevitable future, how one day humans will take control of their conscious minds, get happy and stay happy. But it will come too late for you, Dear Reader… so no point buying the book. Unless you’re extremely rich, of course. Then you can pay for the neurochemical research yourself. “Easy to understand and persuasive” “Reminded me of Douglas Adams and Terry Pratchett”

    Nobel laureate Murray Gell-Mann offers a uniquely personal and unifying vision of the relationship between the fundamental laws of physics and the complexity and diversity of the natural world.

    His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    He showed that, far from being an exotic novelty, Hinduism was an important, legitimate spiritual tradition with valuable lessons for the West. Pathways to Joy is a selection of 108 of his sacred teachings on Vedanta philosophy. In accessible and powerful prose, Vivekananda illuminates the four classical yoga paths — karma, bhakti, raja, and jnana — for the different natures of humankind. The messages focus on the oneness of existence; the divinity of the soul; the truth in all religions; and unifying with the Divine within. Invaluable and inspiring, the selections also explore karma, maya, rebirth, and other great revelations of Hinduism.

    Yet psychologists and philosophers agree that these commonplace approaches to creating happiness, success, and fulfillment make critical mistakes. Stop Chasing Carrots reveals how these mistakes begin with misconceptions about happiness and then presents a philosophy of life to achieve better results.Here is the rare book that creates a philosophy of life based on scientific evidence. Replacing self-help materialism, Eastern spiritualism/minimalism, and complex but insightful psychological studies with an accessible, balanced, and realistic concept, Stop Chasing Carrots empowers readers to lead lives based on proven ideas.

    It challenged the entire edifice of the philosophy and learning of Bacon's time, and left its mark on all subsequent discussions of scientific method. This volume presents a new translation of the text into modern English by Michael Silverthorne, together with an introduction by Lisa Jardine that sets the work in the context of Bacon's scientific and philosophical activities.

    Covers the key historical developments and philosophical themes and topics that have impacted upon our scientific view of the world around us Introduces fundamental conceptual issues, including truth, empirical facts and philosophical/conceptual "facts," falsifiability, and instrumentalism /realism Analyzes the transition from the Aristotelian worldview to the Newtonian worldview Explores challenges to our own western worldview brought on by developments in twentieth-century science, most notably relativity theory and quantum theory

    Comparing the key events of the Old Testament with the latest findings in physics, biochemistry, and paleontology, a physicist and theologian shows that science and the Bible can be reconciled to resolve the age-old debates about God.

    In this exciting sequel, Barbara Hand Clow takes these teachings to a practical level so that we can all discover multidimensionality in our daily lives.Based on more than ten years of experience with students, and years of research into the new sciences that validate the breakthrough concepts in The Pleiadian Agenda, Clow presents each dimension in detail. Alchemy of Nine Dimensions reveals how the Pleiadians described the nine dimensionssharpens our understanding with scientific and historical explanationsoffers a startling interpretation of crop circleshelps you contact and work with beings in many dimensions, and provides meditations on how to ground these nine dimensions of awareness energetically into our bodiesFinally, Clow reveals the true significance of the date December 21, 2012--the end of the Mayan calendar--and tells you what you need to know to begin physical and spiritual preparation.

    His simple but staggering theory of quantum evolution shows how quantum mechanics gives living organisms the ability to initiate specific actions, including new mutations. As Paul Davies exclaims, "if these ideas are right, they will transform our understanding of the relationship between physics and biology" and may radically revise the notion of random evolution and the debate over consciousness and free will.
