Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united into a single quantum theory of gravity? Can quantum and cosmos ever be combined? In The Nature of Space and Time, two of the world's most famous physicists-Stephen Hawking (A Brief History of Time) and Roger Penrose (The Road to Reality)-debate these questions.The authors outline how their positions have further diverged on a number of key issues, including the spatial geometry of the universe, inflationary versus cyclic theories of the cosmos, and the black-hole information-loss paradox. Though much progress has been made, Hawking and Penrose stress that physicists still have further to go in their quest for a quantum theory of gravity.

The Little Book of String Theory offers a short, accessible, and entertaining introduction to one of the most talked-about areas of physics today. String theory has been called the "e;theory of everything."e; It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory.Steve Gubser begins by explaining Einstein's famous equation E = mc2, quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book.The Little Book of String Theory is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.

As a spiritual autobiography, Kierkegaard's The Point of View for My Work as an Author stands among such great works as Augustine's Confessions and Newman's Apologia pro Vita Sua. Yet Point of View is neither a confession nor a defense; it is an author's story of a lifetime of writing, his understanding of the maze of greatly varied works that make up his oeuvre. Upon the imminent publication of the second edition of Either/Or, Kierkegaard again intended to cease writing. Now was the time for a direct "e;report to history"e; on the authorship as a whole. In addition to Point of View, which was published posthumously, the present volume also contains On My Work as an Author, a contemporary substitute, and the companion piece Armed Neutrality.

The scientific study of complex systems has transformed a wide range of disciplines in recent years, enabling researchers in both the natural and social sciences to model and predict phenomena as diverse as earthquakes, global warming, demographic patterns, financial crises, and the failure of materials. In this book, Didier Sornette boldly applies his varied experience in these areas to propose a simple, powerful, and general theory of how, why, and when stock markets crash. Most attempts to explain market failures seek to pinpoint triggering mechanisms that occur hours, days, or weeks before the collapse. Sornette proposes a radically different view: the underlying cause can be sought months and even years before the abrupt, catastrophic event in the build-up of cooperative speculation, which often translates into an accelerating rise of the market price, otherwise known as a "e;bubble."e; Anchoring his sophisticated, step-by-step analysis in leading-edge physical and statistical modeling techniques, he unearths remarkable insights and some predictions--among them, that the "e;end of the growth era"e; will occur around 2050. Sornette probes major historical precedents, from the decades-long "e;tulip mania"e; in the Netherlands that wilted suddenly in 1637 to the South Sea Bubble that ended with the first huge market crash in England in 1720, to the Great Crash of October 1929 and Black Monday in 1987, to cite just a few. He concludes that most explanations other than cooperative self-organization fail to account for the subtle bubbles by which the markets lay the groundwork for catastrophe. Any investor or investment professional who seeks a genuine understanding of looming financial disasters should read this book. Physicists, geologists, biologists, economists, and others will welcome Why Stock Markets Crash as a highly original "e;scientific tale,"e; as Sornette aptly puts it, of the exciting and sometimes fearsome--but no longer quite so unfathomable--world of stock markets.

This eagerly awaited study brings to completion Louis Dupre's planned trilogy on European culture during the modern epoch. Demonstrating remarkable erudition and sweeping breadth, The Quest of the Absolute analyzes Romanticism as a unique cultural phenomenon and a spiritual revolution. Dupre philosophically reflects on its attempts to recapture the past and transform the present in a movement that is partly a return to premodern culture and partly a violent protest against it. Following an introduction on the historical origins of the Romantic Movement, Dupre examines the principal Romantic poets of England (Wordsworth, Coleridge, Shelley, Keats), Germany (Goethe, Schiller, Novalis, Holderlin), and France (Lamartine, de Vigny, Hugo), all of whom, from different perspectives, pursued an absolute ideal. In the chapters of the second part, he concentrates on the critical principles of Romantic aesthetics, the Romantic image of the person as reflected in the novel, and Romantic ethical and political theories. In the chapters of the third, more speculative, part, he investigates the comprehensive syntheses of romantic thought in history, philosophy, and theology.

The bicycle is almost unique among human-powered machines in that it uses human muscles in a near-optimum way. This new edition of the bible of bicycle builders and bicyclists provides just about everything you could want to know about the history of bicycles, how human beings propel them, what makes them go faster, and what keeps them from going even faster. The scientific and engineering information is of interest not only to designers and builders of bicycles and other human-powered vehicles but also to competitive cyclists, bicycle commuters, and recreational cyclists. The third edition begins with a brief history of bicycles and bicycling that demolishes many widespread myths. This edition includes information on recent experiments and achievements in human-powered transportation, including the "e;ultimate human- powered vehicle,"e; in which a supine rider in a streamlined enclosure steers by looking at a television screen connected to a small camera in the nose, reaching speeds of around 80 miles per hour. It contains completely new chapters on aerodynamics, unusual human-powered machines for use on land and in water and air, human physiology, and the future of bicycling. This edition also provides updated information on rolling drag, transmission of power from rider to wheels, braking, heat management, steering and stability, power and speed, and materials. It contains many new illustrations.

This highly original work presents laboratory science in a deliberately skeptical way: as an anthropological approach to the culture of the scientist. Drawing on recent work in literary criticism, the authors study how the social world of the laboratory produces papers and other "e;texts,"e;' and how the scientific vision of reality becomes that set of statements considered, for the time being, too expensive to change. The book is based on field work done by Bruno Latour in Roger Guillemin's laboratory at the Salk Institute and provides an important link between the sociology of modern sciences and laboratory studies in the history of science.

'A fun, fascinating, and original book that will challenge you to become a better version of yourself'Daniel H. Pink, author of DriveWhat does it take to be truly happy? Should we pursue fame and fortune or the respect of our friends and family? How can we make the world a better place? Two hundred and fifty years ago, Adam Smith addressed these fundamental questions in his life-long project, The Theory of Modern Sentiments.Dwarfed by the success of Smith's masterpiece The Wealth of Nations, The Theory of Modern Sentiments has been virtually forgotten. But when Russ Roberts finally picked up the epic tome, he realized he'd stumbled upon the greatest self-help book that almost no one has read.In How Adam Smith Can Change Your Life, Rob erts reinvigorates the neglected classic to unearth a treasure trove of timeless, practical wisdom that cuts to the core of what it means to be human. It will challenge you to think about the way you treat others, the decisions you make in pursuit of happiness, and your place in the world.

'Why do I know a few more things? Why am I so clever altogether?'Self-celebrating and self-mocking autobiographical writings from Ecce Homo, the last work iconoclastic German philosopher Nietzsche wrote before his descent into madness.One of 46 new books in the bestselling Little Black Classics series, to celebrate the first ever Penguin Classic in 1946. Each book gives readers a taste of the Classics' huge range and diversity, with works from around the world and across the centuries - including fables, decadence, heartbreak, tall tales, satire, ghosts, battles and elephants.

A new translation of Voltaire's Treatise on Toleration, one of the most important essays on religious tolerance and freedom of thought A powerful, impassioned case for the values of freedom of conscience and religious tolerance, Treatise on Toleration was written after the Toulouse merchant Jean Calas was falsely accused of murdering his son and executed on the wheel in 1762. As it became clear that Calas had been persecuted by 'an irrational mob' for being a Protestant, the Enlightenment philosopher Voltaire began a campaign to vindicate him and his family. The resulting work, a screed against fanaticism and a plea for understanding, is as fresh and urgent today as when it was written.

We live in the Information Age, with billions of bytes of data just two swipes away. Yet how much of this is mis- or even disinformation? A lot of it is, and your search engine can't tell the difference. As a result, an avalanche of misinformation threatens to overwhelm the discourse we so desperately need to address complex social problems such as climate change, the food and water crises, biodiversity collapse, and emerging threats to public health. This book provides an inoculation against the misinformation epidemic by cultivating scientific habits of mind. Anyone can do it-indeed, everyone must do it if our species is to survive on this crowded and finite planet.This survival guide supplies an essential set of apps for the prefrontal cortex while making science both accessible and entertaining. It will dissolve your fear of numbers, demystify graphs, and elucidate the key concepts of probability, all while celebrating the precise use of language and logic. David Helfand, one of our nation's leading astronomers and science educators, has taught scientific habits of mind to generations in the classroom, where he continues to wage a provocative battle against sloppy thinking and the encroachment of misinformation.

While post- and decolonial theorists have thoroughly debunked the idea of historical progress as a Eurocentric, imperialist, and neocolonialist fallacy, many of the most prominent contemporary thinkers associated with the Frankfurt School-Jurgen Habermas, Axel Honneth, and Rainer Forst-have defended ideas of progress, development, and modernity and have even made such ideas central to their normative claims. Can the Frankfurt School's goal of radical social change survive this critique? And what would a decolonized critical theory look like?Amy Allen fractures critical theory from within by dispensing with its progressive reading of history while retaining its notion of progress as a political imperative, so eloquently defended by Adorno. Critical theory, according to Allen, is the best resource we have for achieving emancipatory social goals. In reimagining a decolonized critical theory after the end of progress, she rescues it from oblivion and gives it a future.

Michael Onfray passionately defends the potential of hedonism to resolve the dislocations and disconnections of our melancholy age. In a sweeping survey of history's engagement with and rejection of the body, he exposes the sterile conventions that prevent us from realizing a more immediate, ethical, and embodied life. He then lays the groundwork for both a radical and constructive politics of the body that adds to debates over morality, equality, sexual relations, and social engagement, demonstrating how philosophy, and not just modern scientism, can contribute to a humanistic ethics.Onfray attacks Platonic idealism and its manifestation in Judaic, Christian, and Islamic belief. He warns of the lure of attachment to the purportedly eternal, immutable truths of idealism, which detracts from the immediacy of the world and our bodily existence. Insisting that philosophy is a practice that operates in a real, material space, Onfray enlists Epicurus and Democritus to undermine idealist and theological metaphysics; Nietzsche, Bentham, and Mill to dismantle idealist ethics; and Palante and Bourdieu to collapse crypto-fascist neoliberalism. In their place, he constructs a positive, hedonistic ethics that enlarges on the work of the New Atheists to promote a joyful approach to our lives in this, our only, world.

We invoke the ideal of tolerance in response to conflict, but what does it mean to answer conflict with a call for tolerance? Is tolerance a way of resolving conflicts or a means of sustaining them? Does it transform conflicts into productive tensions, or does it perpetuate underlying power relations? To what extent does tolerance hide its involvement with power and act as a form of depoliticization?Wendy Brown and Rainer Forst debate the uses and misuses of tolerance, an exchange that highlights the fundamental differences in their critical practice despite a number of political similarities. Both scholars address the normative premises, limits, and political implications of various conceptions of tolerance. Brown offers a genealogical critique of contemporary discourses on tolerance in Western liberal societies, focusing on their inherent ties to colonialism and imperialism, and Forst reconstructs an intellectual history of tolerance that attempts to redeem its political virtue in democratic societies. Brown and Forst work from different perspectives and traditions, yet they each remain wary of the subjection and abnegation embodied in toleration discourses, among other issues. The result is a dialogue rich in critical and conceptual reflections on power, justice, discourse, rationality, and identity.

The Hegelian-Marxist idea of alienation fell out of favor after the postmetaphysical rejection of humanism and essentialist views of human nature. In this book Rahel Jaeggi draws on the Hegelian philosophical tradition, phenomenological analyses grounded in modern conceptions of agency, and recent work in the analytical tradition to reconceive alienation as the absence of a meaningful relationship to oneself and others, which manifests in feelings of helplessness and the despondent acceptance of ossified social roles and expectations.A revived approach to alienation helps critical social theory engage with phenomena such as meaninglessness, isolation, and indifference. By severing alienation's link to a problematic conception of human essence while retaining its social-philosophical content, Jaeggi provides resources for a renewed critique of social pathologies, a much-neglected concern in contemporary liberal political philosophy. Her work revisits the arguments of Rousseau, Hegel, Kierkegaard, and Heidegger, placing them in dialogue with Thomas Nagel, Bernard Williams, and Charles Taylor.

In the West, we have identified only four basic tastes-sour, sweet, salty, and bitter-that, through skillful combination and technique, create delicious foods. Yet in many parts of East Asia over the past century, an additional flavor has entered the culinary lexicon: umami, a fifth taste impression that is savory, complex, and wholly distinct.Combining culinary history with recent research into the chemistry, preparation, nutrition, and culture of food, Mouritsen and Styrbaek encapsulate what we know to date about the concept of umami, from ancient times to today. Umami can be found in soup stocks, meat dishes, air-dried ham, shellfish, aged cheeses, mushrooms, and ripe tomatoes, and it can enhance other taste substances to produce a transformative gustatory experience. Researchers have also discovered which substances in foodstuffs bring out umami, a breakthrough that allows any casual cook to prepare delicious and more nutritious meals with less fat, salt, and sugar. The implications of harnessing umami are both sensuous and social, enabling us to become more intimate with the subtleties of human taste while making better food choices for ourselves and our families. This volume, the product of an ongoing collaboration between a chef and a scientist, won the Danish national Mad+Medier-Prisen (Food and Media Award) in the category of academic food communication.

Between 1918 and 1933, the masses became a decisive preoccupation of European culture, fueling modernist movements in art, literature, architecture, theater, and cinema, as well as the rise of communism and fascism and experiments in radical democracy. Spanning aesthetics, cultural studies, intellectual history, and political theory, this volume unpacks the significance of the shadow agent known as "e;the mass"e; during a critical period in European history. It follows its evolution into the preferred conceptual tool for social scientists, the ideal slogan for politicians, and the chosen image for artists and writers trying to capture a society in flux and a people in upheaval. This volume is the second installment in Stefan Jonsson's epic study of the crowd and the mass in modern Europe, building on his work in A Brief History of the Masses, which focused on monumental artworks produced in 1789, 1889, and 1989.

In May 1968, Gilles Deleuze was an established philosopher teaching at the innovative Vincennes University, just outside of Paris. Felix Guattari was a political militant and the director of an unusual psychiatric clinic at La Borde. Their meeting was quite unlikely, yet the two were introduced in an arranged encounter of epic consequence. From that moment on, Deleuze and Guattari engaged in a surprising, productive partnership, collaborating on several groundbreaking works, including Anti-Oedipus, What Is Philosophy? and A Thousand Plateaus.Francois Dosse, a prominent French intellectual known for his work on the Annales School, structuralism, and biographies of the pivotal intellectuals Paul Ricoeur, Pierre Chaunu, and Michel de Certeau, examines the prolific if improbable relationship between two men of distinct and differing sensibilities. Drawing on unpublished archives and hundreds of personal interviews, Dosse elucidates a collaboration that lasted more than two decades, underscoring the role that family and history particularly the turbulent time of May 1968 play in their monumental work. He also takes the measure of Deleuze and Guattari's posthumous fortunes and the impact of their thought on intellectual, academic, and professional circles.

Instead of treating art as a unique creation that requires reason and refined taste to appreciate, Elizabeth Grosz argues that art-especially architecture, music, and painting-is born from the disruptive forces of sexual selection. She approaches art as a form of erotic expression connecting sensory richness with primal desire, and in doing so, finds that the meaning of art comes from the intensities and sensations it inspires, not just its intention and aesthetic.By regarding our most cultured human accomplishments as the result of the excessive, nonfunctional forces of sexual attraction and seduction, Grosz encourages us to see art as a kind of bodily enhancement or mode of sensation enabling living bodies to experience and transform the universe. Art can be understood as a way for bodies to augment themselves and their capacity for perception and affection-a way to grow and evolve through sensation. Through this framework, which knits together the theories of Charles Darwin, Henri Bergson, Gilles Deleuze, Felix Guattari, and Jakob von Uexkull, we are able to grasp art's deep animal lineage. Grosz argues that art is not tied to the predictable and known but to new futures not contained in the present. Its animal affiliations ensure that art is intensely political and charged with the creation of new worlds and new forms of living. According to Grosz, art is the way in which life experiments with materiality, or nature, in order to bring about change.

The field of paleoclimatology relies on physical, chemical, and biological proxies of past climate changes that have been preserved in natural archives such as glacial ice, tree rings, sediments, corals, and speleothems. Paleoclimate archives obtained through field investigations, ocean sediment coring expeditions, ice sheet coring programs, and other projects allow scientists to reconstruct climate change over much of earth's history. When combined with computer model simulations, paleoclimatic reconstructions are used to test hypotheses about the causes of climatic change, such as greenhouse gases, solar variability, earth's orbital variations, and hydrological, oceanic, and tectonic processes. This book is a comprehensive, state-of-the art synthesis of paleoclimate research covering all geological timescales, emphasizing topics that shed light on modern trends in the earth's climate. Thomas M. Cronin discusses recent discoveries about past periods of global warmth, changes in atmospheric greenhouse gas concentrations, abrupt climate and sea-level change, natural temperature variability, and other topics directly relevant to controversies over the causes and impacts of climate change. This text is geared toward advanced undergraduate and graduate students and researchers in geology, geography, biology, glaciology, oceanography, atmospheric sciences, and climate modeling, fields that contribute to paleoclimatology. This volume can also serve as a reference for those requiring a general background on natural climate variability.

What are the causes of war? To answer this question, Professor Waltz examines the ideas of major thinkers throughout the history of Western civilization. He explores works both by classic political philosophers, such as St. Augustine, Hobbes, Kant, and Rousseau, and by modern psychologists and anthropologists to discover ideas intended to explain war among states and related prescriptions for peace.

Julia Kristeva refracts the impulse to hate (and our attempts to subvert, sublimate, and otherwise process it) through psychoanalysis and text, exploring worlds, women, religion, portraits, and the act of writing. Her inquiry spans themes, topics, and figures central to her writing, and her paths of discovery advance the theoretical innovations that are so characteristic of her thought.Kristeva rearticulates and extends her analysis of language, abjection, idealization, female sexuality, love, and forgiveness. She examines the "e;maladies of the soul,"e; utilizing examples from her practice and the ailments of her patients, such as fatigue, irritability, and general malaise. She sources the Bible and texts by Marguerite Duras, St. Teresa of Avila, Roland Barthes, Simone de Beauvoir, and Georgia O'Keefe. Balancing political calamity and individual pathology, she addresses internal and external catastrophes and global and personal injuries, confronting the nature of depression, obliviousness, fear, and the agony of being and nothingness. Throughout Kristeva develops the notion that psychoanalysis is the key to serenity, with its processes of turning back, looking back, investigating the self, and refashioning psychical damage into something useful and beautiful. Constant questioning, Kristeva contends, is essential to achieving the coming to terms we all seek at the core of forgiveness.

Modernity in the late eighteenth century transformed all domains of European life -intellectual, industrial, and social. Not least affected was the experience of time itself: ever-accelerating change left people with briefer intervals of time in which to gather new experiences and adapt. In this provocative and erudite book Reinhart Koselleck, a distinguished philosopher of history, explores the concept of historical time by posing the question: what kind of experience is opened up by the emergence of modernity? Relying on an extraordinary array of witnesses and texts from politicians, philosophers, theologians, and poets to Renaissance paintings and the dreams of German citizens during the Third Reich, Koselleck shows that, with the advent of modernity, the past and the future became 'relocated' in relation to each other.The promises of modernity -freedom, progress, infinite human improvement -produced a world accelerating toward an unknown and unknowable future within which awaited the possibility of achieving utopian fulfillment. History, Koselleck asserts, emerged in this crucial moment as a new temporality providing distinctly new ways of assimilating experience. In the present context of globalization and its resulting crises, the modern world once again faces a crisis in aligning the experience of past and present. To realize that each present was once an imagined future may help us once again place ourselves within a temporality organized by human thought and humane ends as much as by the contingencies of uncontrolled events.

Britain's most famous mathematician takes us to the edge of knowledge to show us what we cannot know. Is the universe infinite?Do we know what happened before the Big Bang?Where is human consciousness located in the brain?And are there more undiscovered particles out there, beyond the Higgs boson?In the modern world, science is king: weekly headlines proclaim the latest scientific breakthroughs and numerous mathematical problems, once indecipherable, have now been solved. But are there limits to what we can discover about our physical universe?In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data. Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding?In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there's anything we truly cannot know.

The work of Rudolf Steiner is unique in the way it combines esoteric teaching with practical suggestions for the development of social life. Indeed, Steiner is best known today for the application of his ideas in areas such as education, medicine and agriculture. But none of this could have developed without the coherent and profound body of spiritual knowledge which stands at the very core of Steiner's work. In Rosicrucian Wisdom - one of his most complete introductions to modern spirituality - Steiner speaks out of the stream of Rosicrucian teaching. But rather than borrowing old ideas from historical tradition, Steiner presents a wholly new contribution arising from the results of his own experiential research. He talks of the Rosicrucian path as being appropriate for the modern spiritual seeker, but warns that Rosicrucian teaching should not be taken as abstract theory. Rather than remaining in the head or even the heart, spiritual ideas should reach into daily action, transforming all aspects of life. Steiner goes on to describe many facets of spiritual truth, including the law of destiny, the fact of life after death, ways of developing spiritual vision, humanity's past and future evolution, and much more.
