| existential physics pdf download: Existential Physics Sabine Hossenfelder, 2022-08-09 A NEW YORK TIMES BESTSELLER “An informed and entertaining guide to what science can and cannot tell us.” —The Wall Street Journal “Stimulating . . . encourage[s] readers to push past well-trod assumptions […] and have fun doing so.” —Science Magazine From renowned physicist and creator of the YouTube series “Science without the Gobbledygook,” a book that takes a no-nonsense approach to life’s biggest questions, and wrestles with what physics really says about the human condition Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely. According to Sabine Hossenfelder, it is not a coincidence that quantum entanglement and vacuum energy have become the go-to explanations of alternative healers, or that people believe their deceased grandmother is still alive because of quantum mechanics. Science and religion have the same roots, and they still tackle some of the same questions: Where do we come from? Where do we go to? How much can we know? The area of science that is closest to answering these questions is physics. Over the last century, physicists have learned a lot about which spiritual ideas are still compatible with the laws of nature. Not always, though, have they stayed on the scientific side of the debate. In this lively, thought-provoking book, Hossenfelder takes on the biggest questions in physics: Does the past still exist? Do particles think? Was the universe made for us? Has physics ruled out free will? Will we ever have a theory of everything? She lays out how far physicists are on the way to answering these questions, where the current limits are, and what questions might well remain unanswerable forever. Her book offers a no-nonsense yet entertaining take on some of the toughest riddles in existence, and will give the reader a solid grasp on what we know—and what we don’t know. |
| existential physics pdf download: Lost in Math Sabine Hossenfelder, 2018-06-12 In this provocative book (New York Times), a contrarian physicist argues that her field's modern obsession with beauty has given us wonderful math but bad science. Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these too good to not be true theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth. |

| existential physics pdf download: Effective Spacetime Karen Crowther, 2016-07-07 This book discusses the notion that quantum gravity may represent the breakdown of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered emergent, in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop quantum gravity. |
| existential physics pdf download: Existentialism For Beginners David Cogswell, 2008-10-14 Existentialism For Beginners is an entertaining romp through the history of a philosophical movement that has had a broad and enduring influence on Western culture. From the middle of the Nineteenth Century through the late Twentieth Century, existentialism informed our politics and art, and still exerts its influence today. Tracing the movement’s beginnings with close-up views of seminal figures like Kierkegaard, Dostoyevsky and Nietzsche, Existentialism For Beginners follows its intellectual and literary trail to German philosophers Jaspers and Heidegger, and finally to the movement’s flowering in post-World-War-II France thanks to masterworks by such giants as Jean Paul Sartre, Albert Camus, Simone de Beauvoir, plus many others. Illustrations throughout — at once lighthearted and gritty — help readers explore and understand a style of thinking that, while pervasive in its influence, is often seen as obscure, difficult, cryptic and dark. Existentialism For Beginners draws the movement’s many diverse elements together to provide an accessible introduction for those who seek a better understanding of the topic, and an enjoyable historical review packed with timeless quotes from existentialism’s leading lights. |
| existential physics pdf download: The Theory of Almost Everything Robert Oerter, 2006-09-26 There are two scientific theories that, taken together, explain the entire universe. The first, which describes the force of gravity, is widely known: Einstein’s General Theory of Relativity. But the theory that explains everything else—the Standard Model of Elementary Particles—is virtually unknown among the general public. In The Theory of Almost Everything, Robert Oerter shows how what were once thought to be separate forces of nature were combined into a single theory by some of the most brilliant minds of the twentieth century. Rich with accessible analogies and lucid prose, The Theory of Almost Everything celebrates a heretofore unsung achievement in human knowledge—and reveals the sublime structure that underlies the world as we know it. |
| existential physics pdf download: Sophie's World Jostein Gaarder, 2007-03-20 A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: Who are you? and Where does the world come from? From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined. |
| existential physics pdf download: Practising Existential Psychotherapy Ernesto Spinelli, 2007-08-01 Existential psychotherapy has emerged as an approach that is distinctively different to that of the other models and systems within psychotherapy. It provides a set of significant challenges to, and critiques of, contemporary Western psychotherapy both at the level of theory and of practice. Although a substantial amount of writing that seeks to describe and delineate the theoretical underpinnings of existential psychotherapy already exists, this is not the case with texts dealing with the application of theory in the form of practice. Practising Existential Psychotherapy examines the unique qualities and possibilities of an existential approach to psychotherapy. Drawn from Ernesto Spinelli's own experience as an internationally recognised theorist, lecturer and practitioner, the book's overall aim is to provide a thorough and accessible explication of existential psychotherapy in practice. Beginning with an overview of the theoretical underpinnings and distinguishing features of existential psychotherapy, the text describes and develops a three-phase structural model for its practice. As well as describing the key components of each phase, the text provides descriptive examples and topic-focused exercises designed to assist readers in developing their own practice-based understanding of existential psychotherapy. Ernesto Spinelli is a Professor in the School of Psychotherapy and Counselling at Regent's College, London. |
| existential physics pdf download: Physics of the Impossible Michio Kaku, 2008-03-11 NATIONAL BESTSELLER • Inspired by the fantastic worlds of Star Trek, Star Wars, and Back to the Future, the renowned theoretical physicist and national bestselling author of The God Equation takes an informed, serious, and often surprising look at what our current understanding of the universe's physical laws may permit in the near and distant future. Teleportation, time machines, force fields, and interstellar space ships—the stuff of science fiction or potentially attainable future technologies? Entertaining, informative, and imaginative, Physics of the Impossible probes the very limits of human ingenuity and scientific possibility. |
| existential physics pdf download: Biopoetics Andreas Weber, 2016-09-01 Meaning, feeling and expression – the experience of inwardness – matter most in human existence. The perspective of biopoetics shows that this experience is shared by all organisms. Being alive means to exist through relations that have existential concern, and to express these dimensions through the body and its gestures. All life takes place within one poetic space which is shared between all beings and which is accessible through subjective sensual experience. We take part in this through our empirical subjectivity, which arises from the experiences and needs of living beings, and which makes them open to access and sharing in a poetic objectivity. Biopoetics breaks free from the causal-mechanic paradigm which made biology unable to account for mind and meaning. Biology becomes a science of expression, connection and subjectivity which can understand all organisms including humans as feeling agents in a shared ecology of meaningful relations, embedded in a symbolical and material metabolism of the biosphere. |
| existential physics pdf download: How the Laws of Physics Lie Nancy Cartwright, 1983-06-09 In this sequence of philosophical essays about natural science, Nancy Cartwright argues that fundamental explanatory laws, the deepest and most admired successes of modern physics, do not in fact describe the regularities that exist in nature. Yet she is not `anti-realist'. Rather, she draws a novel distinction, arguing that theoretical entities, and the complex and localized laws that describe them, can be interpreted realistically, but that the simple unifying laws of basic theory cannot. |

| existential physics pdf download: The Uninhabitable Earth David Wallace-Wells, 2019-02-19 #1 NEW YORK TIMES BESTSELLER • “The Uninhabitable Earth hits you like a comet, with an overflow of insanely lyrical prose about our pending Armageddon.”—Andrew Solomon, author of The Noonday Demon NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New Yorker • The New York Times Book Review • Time • NPR • The Economist • The Paris Review • Toronto Star • GQ • The Times Literary Supplement • The New York Public Library • Kirkus Reviews It is worse, much worse, than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible—food shortages, refugee emergencies, climate wars and economic devastation. An “epoch-defining book” (The Guardian) and “this generation’s Silent Spring” (The Washington Post), The Uninhabitable Earth is both a travelogue of the near future and a meditation on how that future will look to those living through it—the ways that warming promises to transform global politics, the meaning of technology and nature in the modern world, the sustainability of capitalism and the trajectory of human progress. The Uninhabitable Earth is also an impassioned call to action. For just as the world was brought to the brink of catastrophe within the span of a lifetime, the responsibility to avoid it now belongs to a single generation—today’s. LONGLISTED FOR THE PEN/E.O. WILSON LITERARY SCIENCE WRITING AWARD “The Uninhabitable Earth is the most terrifying book I have ever read. Its subject is climate change, and its method is scientific, but its mode is Old Testament. The book is a meticulously documented, white-knuckled tour through the cascading catastrophes that will soon engulf our warming planet.”—Farhad Manjoo, The New York Times “Riveting. . . . Some readers will find Mr. Wallace-Wells’s outline of possible futures alarmist. He is indeed alarmed. You should be, too.”—The Economist “Potent and evocative. . . . Wallace-Wells has resolved to offer something other than the standard narrative of climate change. . . . He avoids the ‘eerily banal language of climatology’ in favor of lush, rolling prose.”—Jennifer Szalai, The New York Times “The book has potential to be this generation’s Silent Spring.”—The Washington Post “The Uninhabitable Earth, which has become a best seller, taps into the underlying emotion of the day: fear. . . . I encourage people to read this book.”—Alan Weisman, The New York Review of Books |
| existential physics pdf download: Nietzsche’s Meta-Existentialism Vinod Acharya, 2013-11-27 Vinod Acharya presents a new existential interpretation of Nietzsche's philosophy. He contends that Nietzsche's peculiar form of existentialism can be understood only by undertaking a thorough analysis of his characterization and critique of metaphysics. This reading remedies the shortcomings of previous existential interpretations of Nietzsche, which typically view existentialism as concerned primarily with the meaning of individual existence, and therefore necessarily at odds with the abstraction and objectivity of metaphysical thought. Acharya argues that the approach of Nietzsche's philosophy, especially in his mature works, is to make the typical existential position foundational, and then to develop to the fullest the implications of this position. This meta-existential approach necessarily yields an ambiguous and open-ended critique of metaphysics. Taking issue with the Heideggerian, the poststructuralist, and the naturalistic interpretations, this book contends that Nietzsche neither simply overcomes metaphysics nor remains trapped within its confines. Acharya argues that an ever-renewed encounter with and critique of metaphysics is an essential aspect of Nietzsche's meta-existentialism. |
| existential physics pdf download: Six Easy Pieces Richard P. Feynman, 1996-04-10 Richard P. Feynman (1918–1988) was widely recognized as the most creative physicist of the post–World War II period. His career was extraordinarily expansive. From his contributions to the development of the atomic bomb a Los Alamos during World War II to his work in quantum electrodynamics, for which he was awarded the Nobel Prize in 1965, Feynman was celebrated for his brilliant and irreverent approach to physics.It was Feynman's outrageous and scintillating method of teaching that earned him legendary status among students and professors of physics. From 1961–1963, Feynman, at the California Institute of Technology, delivered a series of lectures that revolutionized the teaching of physics around the world. Six Easy Pieces, taken from the famous Lectures on Physics, represents the most accessible material from this series. In these six chapters, Feynman introduces the general reader to the following topics: atoms, basic physics, the relationship of physics to other topics, energy, gravitation, and quantum force. With his dazzling and inimitable wit, Feynman presents each discussion without equations or technical jargon.Readers will remember how—using ice water and rubber—Feynman demonstrated with stunning simplicity to a nationally televised audience the physics of the 1986 Challenger disaster. It is precisely this ability—the clear and direct illustration of complex theories—that made Richard Feynman one of the most distinguished educators in the world. Filled with wonderful examples and clever illustrations, Six Easy Pieces is the ideal introduction to the fundamentals of physics by one of the most admired and accessible scientists of our time. |
| existential physics pdf download: Understanding Philosophy of Science James Ladyman, 2012-08-06 Few can imagine a world without telephones or televisions; many depend on computers and the Internet as part of daily life. Without scientific theory, these developments would not have been possible. In this exceptionally clear and engaging introduction to philosophy of science, James Ladyman explores the philosophical questions that arise when we reflect on the nature of the scientific method and the knowledge it produces. He discusses whether fundamental philosophical questions about knowledge and reality might be answered by science, and considers in detail the debate between realists and antirealists about the extent of scientific knowledge. Along the way, central topics in philosophy of science, such as the demarcation of science from non-science, induction, confirmation and falsification, the relationship between theory and observation and relativism are all addressed. Important and complex current debates over underdetermination, inference to the best explaination and the implications of radical theory change are clarified and clearly explained for those new to the subject. |
| existential physics pdf download: The Biggest Ideas in the Universe Sean Carroll, 2022-09-20 INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come. |

| existential physics pdf download: Fashionable Nonsense Alan Sokal, Jean Bricmont, 2014-01-14 In 1996 physicist Alan Sokal published an essay in Social Text--an influential academic journal of cultural studies--touting the deep similarities between quantum gravitational theory and postmodern philosophy. Soon thereafter, the essay was revealed as a brilliant parody, a catalog of nonsense written in the cutting-edge but impenetrable lingo of postmodern theorists. The event sparked a furious debate in academic circles and made the headlines of newspapers in the U.S. and abroad. In Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science, Sokal and his fellow physicist Jean Bricmont expand from where the hoax left off. In a delightfully witty and clear voice, the two thoughtfully and thoroughly dismantle the pseudo-scientific writings of some of the most fashionable French and American intellectuals. More generally, they challenge the widespread notion that scientific theories are mere narrations or social constructions. |
| existential physics pdf download: Neuroexistentialism Gregg D. Caruso, Owen J. Flanagan, 2018 Existentialisms arise when the foundations of being, such as meaning, morals, and purpose come under assault. In the first-wave of existentialism, writings typified by Kierkegaard, Dostoevsky, and Nietzsche concerned the increasingly apparent inability of religion, and religious tradition, to support a foundation of being. Second-wave existentialism, personified philosophically by Sartre, Camus, and de Beauvoir, developed in response to similar realizations about the overly optimistic Enlightenment vision of reason and the common good. The third-wave of existentialism, a new existentialism, developed in response to advances in the neurosciences that threaten the last vestiges of an immaterial soul or self. Given the increasing explanatory and therapeutic power of neuroscience, the mind no longer stands apart from the world to serve as a foundation of meaning. This produces foundational anxiety. In Neuroexistentialism, a group of contributors that includes some of the world's leading philosophers, neuroscientists, cognitive scientists, and legal scholars, explores the anxiety caused by third-wave existentialism and possible responses to it. Together, these essays tackle our neuroexistentialist predicament, and explore what the mind sciences can tell us about morality, love, emotion, autonomy, consciousness, selfhood, free will, moral responsibility, law, the nature of criminal punishment, meaning in life, and purpose. |
| existential physics pdf download: The Ego Tunnel Thomas Metzinger, 2010-05-21 We're used to thinking about the self as an independent entity, something that we either have or are. In The Ego Tunnel, philosopher Thomas Metzinger claims otherwise: No such thing as a self exists. The conscious self is the content of a model created by our brain - an internal image, but one we cannot experience as an image. Everything we experience is ''a virtual self in a virtual reality.'' But if the self is not ''real,'' why and how did it evolve? How does the brain construct it? Do we still have souls, free will, personal autonomy, or moral accountability? In a time when the science of cognition is becoming as controversial as evolution, The Ego Tunnel provides a stunningly original take on the mystery of the mind. |
| existential physics pdf download: How to Prove It Daniel J. Velleman, 2006-01-16 Many students have trouble the first time they take a mathematics course in which proofs play a significant role. This new edition of Velleman's successful text will prepare students to make the transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs. The book begins with the basic concepts of logic and set theory, to familiarize students with the language of mathematics and how it is interpreted. These concepts are used as the basis for a step-by-step breakdown of the most important techniques used in constructing proofs. The author shows how complex proofs are built up from these smaller steps, using detailed 'scratch work' sections to expose the machinery of proofs about the natural numbers, relations, functions, and infinite sets. To give students the opportunity to construct their own proofs, this new edition contains over 200 new exercises, selected solutions, and an introduction to Proof Designer software. No background beyond standard high school mathematics is assumed. This book will be useful to anyone interested in logic and proofs: computer scientists, philosophers, linguists, and of course mathematicians. |
| existential physics pdf download: Existential Monday Benjamin Fondane, 2016-05-17 Benjamin Fondane—who was born and educated in Romania, moved as an adult to Paris, lived for a time in Buenos Aires, where he was close to Victoria Ocampo, Jorge Luis Borges’s friend and publisher, and died in Auschwitz—was an artist and thinker who found in every limit, in every border, “a torture and a spur.” Poet, critic, man of the theater, movie director, Fondane was the most daring of the existentialists, a metaphysical anarchist, affirming individual against those great abstractions that limit human freedom—the State, History, the Law, the Idea. Existential Monday, the first selection of his philosophical work to appear in English, includes four of Fondane's most thought-provoking and important texts, Existential Monday and the Sunday of History, Preface for the Present Moment, Man Before History (co-translated by Andrew Rubens), and Boredom. Here Fondane, until now little-known except to specialists, emerges as one of the enduring French philosophers of the twentieth century. |
| existential physics pdf download: Advanced Calculus (Revised Edition) Lynn Harold Loomis, Shlomo Zvi Sternberg, 2014-02-26 An authorised reissue of the long out of print classic textbook, Advanced Calculus by the late Dr Lynn Loomis and Dr Shlomo Sternberg both of Harvard University has been a revered but hard to find textbook for the advanced calculus course for decades.This book is based on an honors course in advanced calculus that the authors gave in the 1960's. The foundational material, presented in the unstarred sections of Chapters 1 through 11, was normally covered, but different applications of this basic material were stressed from year to year, and the book therefore contains more material than was covered in any one year. It can accordingly be used (with omissions) as a text for a year's course in advanced calculus, or as a text for a three-semester introduction to analysis.The prerequisites are a good grounding in the calculus of one variable from a mathematically rigorous point of view, together with some acquaintance with linear algebra. The reader should be familiar with limit and continuity type arguments and have a certain amount of mathematical sophistication. As possible introductory texts, we mention Differential and Integral Calculus by R Courant, Calculus by T Apostol, Calculus by M Spivak, and Pure Mathematics by G Hardy. The reader should also have some experience with partial derivatives.In overall plan the book divides roughly into a first half which develops the calculus (principally the differential calculus) in the setting of normed vector spaces, and a second half which deals with the calculus of differentiable manifolds. |
| existential physics pdf download: God and the New Physics P. C. W.

This book is currently used as a research text at universities on six continents and will shortly be available in nine different languages. |
| existential physics pdf download: Science and Moral Imagination Matthew J. Brown, 2020-11-17 The idea that science is or should be value-free, and that values are or should be formed independently of science, has been under fire by philosophers of science for decades. Science and Moral Imagination directly challenges the idea that science and values cannot and should not influence each other. Matthew J. Brown argues that science and values mutually influence and implicate one another, that the influence of values on science is pervasive and must be responsibly managed, and that science can and should have an influence on our values. This interplay, he explains, must be guided by accounts of scientific inquiry and value judgment that are sensitive to the complexities of their interactions. Brown presents scientific inquiry and value judgment as types of problem-solving practices and provides a new framework for thinking about how we might ethically evaluate episodes and decisions in science, while offering guidance for scientific practitioners and institutions about how they can incorporate value judgments into their work. His framework, dubbed “the ideal of moral imagination,” emphasizes the role of imagination in value judgment and the positive role that value judgment plays in science. |
| existential physics pdf download: Architectural Atmospheres Christian Borch, 2014-05-02 Architecture is increasingly understood to be a sensual, spatial experience, which means that the experience of buildings and spatial constellations is also a perception of atmospheres that are rated as positive or negative. Architects, planners, investors, and politicians must produce effects such as these according to intersubjective and communicable criteria, and not intuitively or randomly. Architectural Atmospheres addresses the growing awareness of the atmospheric dimension of architecture and provides a current, programmatic discussion of this topic. What possibilities does this approach open to architecture, what value does this knowledge have? Three essays and a conversation lead a cross-discipline discussion on the impact of architecture, and contribute to the debate first initiated by Peter Zumthor. The texts are accompanied by thirty-five color images that capture architectural moods in a variety of ways. Gernot Böhme is Professor Emeritus of Philosophy at Darmstadt Technical University and Director of the Institute for Practical Philosophy, e.V., Ipph, in Darmstadt, Germany. Christian Borch is Professor of Political Sociology at the Department of Management, Politics, and Philosophy, Copenhagen Business School, Denmark. Olafur Eliasson is a Danish-Icelandic artist. Eliasson incessantly explores our modes of perceiving. His work spans photography, installation, sculpture, and film. Juhani Pallasmaa is one of Finland's most distinguished architects and architectural thinkers. |
| existential physics pdf download: Existentialism Kevin Aho, 2014-04-10 Existentialism: An Introduction provides an accessible and scholarly introduction to the core ideas of the existentialist tradition. Kevin Aho draws on a wide range of existentialist thinkers in chapters centering on the key themes of freedom, being-in-the-world, alienation, nihilism, anxiety and authenticity. He also addresses important but often overlooked issues in the canon of existentialism, with discussions devoted to the role of embodiment, the movement’s contribution to ethics, politics, and environmental and comparative philosophies, as well as its influence on contemporary psychiatry and psychotherapy. The enduring relevance of existentialism is shown by applying existentialist ideas to contemporary philosophical discussions of interest to a wide audience. The book covers secular thinkers such as Heidegger, Merleau-Ponty, Nietzsche, Sartre, Camus, and Beauvoir as well as religious authors, such as Buber, Dostoevsky, Marcel, and Kierkegaard. In this engaging and accessible text Aho shows why existentialism cannot be easily dismissed as a moribund or outdated movement. In the aftermath of 'God’s death', existentialist philosophy engages questions with lasting philosophical significance, questions such as 'Who am I?' and 'How should I live?' By showing how existentialism offers insight into what it means to be human, the author illuminates existentialism’s enduring value. Existentialism: An Introduction provides the ideal introduction for upper level students and anyone interested in knowing more about one of the most vibrant and important areas of philosophy today. |
| existential physics pdf download: Between Past and Future Hannah Arendt, Jerome Kohn, 2006-09-26 From the author of Eichmann in Jerusalem and The Origins of Totalitarianism, “a book to think with through the political impasses and cultural confusions of our day” (Harper’s Magazine) Hannah Arendt’s insightful observations of the modern world, based on a profound knowledge of the past, constitute an impassioned contribution to political philosophy. In Between Past and Future Arendt describes the perplexing crises modern society faces as a result of the loss of meaning of the traditional key words of politics: justice, reason, responsibility, virtue, and glory. Through a series of eight exercises, she shows how we can redistill the vital essence of these concepts and use them to regain a frame of reference for the future. To participate in these exercises is to associate, in action, with one of the most original and fruitful minds of the twentieth century. |
| existential physics pdf download: Existential Theology Hue Woodson, 2020-09-29 Existential Theology: An Introduction offers a formalized and comprehensive examination of the field of existential theology, in order to distinguish it as a unique field of study and view it as a measured synthesis of the concerns of Christian existentialism, Christian humanism, and Christian philosophy with the preoccupations of proper existentialism and a series of unfolding themes from Augustine to Kierkegaard. To do this, Existential Theology attends to the field through the exploration of genres: the European traditions in French, Russian, and German schools of thought, counter-traditions in liberation, feminist, and womanist approaches, and postmodern traditions located in anthropological, political, and ethical approaches. While the cultural contexts inform how each of the selected philosopher-theologians present genres of existential theology, other unique genres are examined in theoretical and philosophical contexts, particularly through a selected set of theologians, philosophers, thinkers, and theorists that are not generally categorized theologically. By assessing existential theology through how it manifests itself in genres, this book brings together lesser-known figures, well-known thinkers, and figures that are not generally viewed as existential theologians to form a focused understanding of the question of the meaning of existential theology and what existential theology looks like in its varying forms. |
| existential physics pdf download: The Philosophy of Quantum Physics Cord Friebe, Meinard Kuhlmann, Holger Lyre, Paul M. Näger, Oliver Passon, Manfred Stöckler, 2018-06-21 This book provides a thorough and up-to-date introduction to the philosophy of quantum physics. Although quantum theory is renowned for its spectacular empirical successes, controversial discussion about how it should be understood continue to rage today. In this volume, the authors provide an overview of its numerous philosophical challenges: Do quantum objects violate the principle of causality? Are particles of the same type indistinguishable and therefore not individual entities? Do quantum objects retain their identity over time? How does a compound quantum system relate to its parts? These questions are answered here within different interpretational approaches to quantum theory. Finally, moving to Quantum Field Theory, we find that the problem of non-locality is exacerbated. Philosophy of quantum physics is aimed at philosophers with an interest in physics, while also serving to familiarize physicists with many of the essential philosophical questions of their subject. |

| existential physics pdf download: Zero Distance Danah Zohar, 2022 When Danah Zohar first published the early ideas of her Quantum Management Theory in the late 1990's, she articulated a new paradigm, inspired by quantum physics, and began a major contribution to our search for a new management theory that can replace outdated Taylorism. Now, in ZERO DISTANCE, the most comprehensive account of her project, she outlines how the theory has been implemented through the revolutionary RenDanHeyi business model of China's Haier Group, and subsequently several other large companies. Zohar's suggestion that the Haier model also offers a new social and political model is thought provoking. This book is a significant addition to our continuing conversation about the best way to manage companies and other human social systems. I recommend it highly. - Gary Hamel, London Business School, Author of Humanocracy This open access book offers a new management meta-theory to replace Taylorism. It presents a new paradigm in management thinking and a new, practical organizational model for implementing it in our personal and working lives, in our companies, in our communities and nations, and in a sustainable global order. It will offer an understanding of why and how thinking-as-usual is failing both business and political leaders in these new times, and it will advocate new thinking and new management practices that are so radically new that they turn everything we have taken for granted inside out and upside down. This new management model is called Quantum Management Theory, because it is rooted in the new paradigm bequeathed to us by quantum physics and its younger sibling, complexity science. Danah Zohar is a physicist, philosopher, and management thought leader. She is a Visiting Professor at Tsinghua University's School of Economics and Management and a Visiting Professor at the China Academy of Art. |
| existential physics pdf download: Introduction to Algebraic and Constructive Quantum Field Theory John C. Baez, Irving E. Segal, Zhengfang Zhou, 2014-07-14 The authors present a rigorous treatment of the first principles of the algebraic and analytic core of quantum field theory. Their aim is to correlate modern mathematical theory with the explanation of the observed process of particle production and of particle-wave duality that heuristic quantum field theory provides. Many topics are treated here in book form for the first time, from the origins of complex structures to the quantization of tachyons and domains of dependence for quantized wave equations. This work begins with a comprehensive analysis, in a universal format, of the structure and characterization of free fields, which is illustrated by applications to specific fields. Nonlinear local functions of both free fields (or Wick products) and interacting fields are established mathematically in a way that is consistent with the basic physical constraints and practice. Among other topics discussed are functional integration, Fourier transforms in Hilbert space, and implementability of canonical transformations. The authors address readers interested in fundamental mathematical physics and who have at least the training of an entering graduate student. A series of lexicons connects the mathematical development with the underlying physical motivation or interpretation. The examples and problems illustrate the theory and relate it to the scientific literature. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

| existential physics pdf download: Electrodynamics: The Field-Free Approach Kjell Prytz, 2015-03-19 This book is intended as an undergraduate textbook in electrodynamics at basic or advanced level. The objective is to attain a general understanding of the electrodynamic theory and its basic experiments and phenomena in order to form a foundation for further studies in the engineering sciences as well as in modern quantum physics. The outline of the book is obtained from the following principles: • Base the theory on the concept of force and mutual interaction • Connect the theory to experiments and observations accessible to the student • Treat the electric, magnetic and inductive phenomena cohesively with respect to force, energy, dipoles and material • Present electrodynamics using the same principles as in the preceding mechanics course • Aim at explaining that theory of relativity is based on the magnetic effect • Introduce field theory after the basic phenomena have been explored in terms of force Although electrodynamics is described in this book from its 1st principles, prior knowledge of about one semester of university studies in mathematics and physics is required, including vector algebra, integral and differential calculus as well as a course in mechanics, treating Newton’s laws and the energy principle. The target groups are physics and engineering students, as well as professionals in the field, such as high school teachers and employees in the telecom industry. Chemistry and computer science students may also benefit from the book. |
| existential physics pdf download: The Divided Self R. D. Laing, 2010-01-28 The Divided Self, R.D. Laing's groundbreaking exploration of the nature of madness, illuminated the nature of mental illness and made the mysteries of the mind comprehensible to a wide audience. First published in 1960, this watershed work aimed to make madness comprehensible, and in doing so revolutionized the way we perceive mental illness. Using case studies of patients he had worked with, psychiatrist R. D. Laing argued that psychosis is not a medical condition, but an outcome of the 'divided self', or the tension between the two personas within us: one our authentic, private identity, and the other the false, 'sane' self that we present to the world. Laing's radical approach to insanity offered a rich existential analysis of personal alienation and made him a cult figure in the 1960s, yet his work was most significant for its humane attitude, which put the patient back at the centre of treatment. Includes an introduction by Professor Anthony S. David.

| existential physics pdf download: Integrated Truth and Existential Phenomenology Robert C. Trundle, 2015-07-14 Integrated Truth and Existential Phenomenology: A Thomistic Response to Iconic Anti-Realists in Science relates an existential phenomenology to modal reasoning. By this reasoning, rooted in a consciousness of phenomena in themselves, a Thomistic realism is advanced wherein scientific inquiry yields objective truth and presupposes a causal principle. This principle, as an inferably true modality, strictly implies a first cause. And this cause as a supreme norm, causally created human nature as it ought to be. So with no naturalistic fallacy, a naturalistic ethics is inferred from our psycho-biological nature that also informs art and politics. Politics, as the institutionalization of ethics, is inferable from ethical prescriptions that are as certifiably true as the descriptions of science that inform it. |
| existential physics pdf download: Being and Having Gabriel Marcel, 2011-03-23 I hope that this book will be widely read, and I especially commend it to four classes of persons: I. For myself I have come across nothing more important than M. Marcel’s writings here and elsewhere on the problem of metaphysics. I say problem advisedly: for we are all of us these days in the end puzzled as to what exactly metaphysics is. The strict Thomist has his answer: so has the positivist: so too the Biblical theologian who is much too ready to find in the decay of ontology an argument for the authenticity of ‘Biblical perspectives’. M. Marcel was trained in the tradition of idealism: and he knew the influence both of Bergsen and of W. E. Hocking. His conversation with himself certainly betrays their influences: but it is of far wider significance. Professor Ayer and Dr. E. L. Mascall have their answer to the question what ontology is: they have their formulae. Marcel probes beneath these answers; for him ontology is much more than a body of doctrine. It is the intellectual expression of the human situation; what is expressed in the syllogisms of, for instance, Père Garrigou-Lagrange, is valid only in so far as it catches and summarises the very being of man and the universe, as that being is lived through and met with by man in his pilgrimage through life. I find as I read M. Marcel that the frontiers are blurred reflection, metaphysics, spirituality. And that is the strength of his seemingly inconsequent method. In a way he is too wise to suppose that the arguments of the philosophia perennis are enough in their abstract form to convince a man; they only carry conviction in relation to a whole experience of life of which they are the expression. The issues between the Thomist, the positivist, the idealist are not issues simply of doctrine but of life; and to see what they are, one must probe, stretching language beyond the frontiers of poetry, somehow to convey the issues as things through which men live. 2. The book should be studied closely by the moralist whether he be philosopher or moral theologian. Where some of the most familiar ethical ideas are concerned, Marcel reminds us of their ‘inside’ when we so often in our discussion think simply of their ‘outside’. What is a promise? We have our answer pat, our formula which permits us to go on with the discussion of our obligations to keep the promises we have made and so on. We don’t wait to probe. I find myself inevitably using that word ‘probe’ again and again in connection with M. Marcel: for what he does is to probe the unsuspected profundities of the familiar. Most professional students of ethics are morally philistine, men who give little time to penetrating the ‘inside’ of the ideas they are handling. And there Marcel pulls them up short. 3. The book should be widely read by the many Christian ‘fellow-travellers’ of today, those who follow, as it were, afar off the Christian way without themselves coming yet to the point of an act of faith in the Crucified. Its very incompleteness will respond to their groping anxiety, and it will enrich their vision of life. And this it can do because it eschews dogmatic exposition seeking rather to shew the inside of the truly Christian way of life. Fidelity, hope, charity, mystery—these are fundamental categories of the Christian way: and of all these Marcel has much to say, which is in every way fresh and yet at the same time rooted in the tradition of Catholic Christianity. The reader of such a work as Albert Camus’ La Peste, with its preoccupation with the problem of an atheistic sanctity, will understand M. Marcel. In a way he challenges the possibility of Camus’ vision; and he does so not on dogmatic grounds but by an analysis of holiness and goodness which shews indirectly their inseparability from acknowledgment of the all-embracing mystery of God. An age which has known evil as ours has and does still know it, is inevitably interested in goodness; and it is with goodness, as something inevitably issuing out of God because a gift from him, that Marcel’s studies deal. 4. And lastly I commend this book because at a time when minuteness and subtlety of mind are too often the prerogatives of the light-heartedly destructive, he reminds us that a true minuteness and a true intellectual subtlety are rooted in humility and purity of heart, and manifest the soil in which they are nourished by graciousness whose charm none can escape and a strength of argument which none can break. |
