At what point does theory depart the realm of testable hypothesis and come to resemble something like aesthetic speculation, or even theology? The legendary physicist Wolfgang Pauli had a phrase for such ideas: He would describe them as "not even wrong," meaning that they were so incomplete that they could not even be used to make predictions to compare with observations to see whether they were wrong or not. In Peter Woit's view, superstring theory is just such an idea. In Not Even Wrong , he shows that what many physicists call superstring "theory" is not a theory at all. It makes no predictions, even wrong ones, and this very lack of falsifiability is what has allowed the subject to survive and flourish. Not Even Wrong explains why the mathematical conditions for progress in physics are entirely absent from superstring theory today and shows that judgments about scientific statements, which should be based on the logical consistency of argument and experimental evidence, are instead based on the eminence of those claiming to know the truth. In the face of many books from enthusiasts for string theory, this book presents the other side of the story.

How does science work? Does it tell us what the world is “really” like? What makes it different from other ways of understanding the universe? In Theory and Reality, Peter Godfrey-Smith addresses these questions by taking the reader on a grand tour of more than a hundred years of debate about science. The result is a completely accessible introduction to the main themes of the philosophy of science. Examples and asides engage the beginning student, a glossary of terms explains key concepts, and suggestions for further reading are included at the end of each chapter. Like no other text in this field, Theory and Reality combines a survey of recent history of the philosophy of science with current key debates that any beginning scholar or critical reader can follow. The second edition is thoroughly updated and expanded by the author with a new chapter on truth, simplicity, and models in science.

Hegel is making a comeback. After the decline of the Marxist Hegelianism that dominated the twentieth century, leading thinkers are rediscovering Hegel’s thought as a resource for contemporary politics. What does a notoriously difficult nineteenth-century German philosopher have to offer the present? How should we understand Hegel, and what does understanding Hegel teach us about confronting our most urgent challenges? In this book, Todd McGowan offers us a Hegel for the twenty-first century. Simultaneously an introduction to Hegel and a fundamental reimagining of Hegel’s project, Emancipation After Hegel presents a radical Hegel who speaks to a world overwhelmed by right-wing populism, authoritarianism, neoliberalism, and economic inequalities. McGowan argues that the revolutionary core of Hegel’s thought is contradiction. He reveals that contradiction is inexorable and that we must attempt to sustain it rather than overcoming it or dismissing it as a logical failure. McGowan contends that Hegel’s notion of contradiction, when applied to contemporary problems, challenges any assertion of unitary identity as every identity is in tension with itself and dependent on others. An accessible and compelling reinterpretation of an often-misunderstood thinker, this book shows us a way forward to a new politics of emancipation as we reconcile ourselves to the inevitability of contradiction and find solidarity in not belonging.

There is no consensus in the social and cultural sciences on what theory is, and that is as it should be. A consensus would be outright dangerous for the diversity of intellectual life. The perspectives represented in this volume show that theory can be understood as plot, hope, beholding, doxa, heritage, a stalemate, disappointment, personal matter, or family concept. But, even if theory can be defined in many ways, it cannot be defined in any one way. Beyond disciplinary and epistemological differences, theory has the steadfast characteristic of being what academics work with. More than an epistemological matter, the book's title question is an entry into the dynamics of academic practice. The book consists of a multidisciplinary collection of essays that are tied together by a common effort to tell what theory is. These essays are also paired as dialogues between senior and junior researchers from the same, or allied, disciplines to add a trans-generational dimension to the book's multidisciplinary approach. What Is Theory? has been designed for upper division and graduate students in the social sciences and the humanities, but it will also be of interest to anyone who has felt that the question of what theory is can be more easily asked than answered. Contents include: Why Ask What Theory Is? * The History of the Concept of Theory * History of Ideas at the End of Western Dominance * Looking at Theory in Theory in Science * Theory Has No Big Others in Science and Technology Studies * What Social Science Theory Is and What It Is Not * Theory as Hope * Theory Crisis and the Necessity of Theory - The Dilemmas of Sociology * Theory as Disappointment * Theory - A Personal Matter * Theory - A Professional Matter * Economic Theory - A Critical Realist Perspective * For Theoretical Pluralism in Economic Theory * What Is Theory in Political Science? * For a New Vocabulary of Theory in Political Science * Theorizing the Earth * Spatial Theory as an Interdisciplinary Praxis. *** "This highly original, lively and refreshing book is more than welcome: it is needed....the contributors' insights, passion and diversity fully restore the creative value of theorizing as a way to grasp, understand and more importantly shape the world." - Franck Cochoy, Professor of Sociology, U. of Toulouse

Physics World's 'Book of the Year' for 2016 An Entertaining and Enlightening Guide to the Who, What, and Why of String Theory, now also available in an updated reflowable electronic format compatible with mobile devices and e-readers. During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering a highly readable and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics. The author, a theoretical physics professor at the University of Oxford and a leading string theorist, explains what string theory is and where it originated. He describes how string theory fits into physics and why so many physicists and mathematicians find it appealing when working on topics from M-theory to monsters and from cosmology to superconductors.

"A thorough, illuminating exploration of the most consequential controversy raging in modern science." --New York Times Book Review An Editor's Choice, New York Times Book Review Longlisted for PEN/E.O. Wilson Prize for Literary Science Writing Longlisted for Goodreads Choice Award Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's solipsistic and poorly reasoned Copenhagen interpretation. Indeed, questioning it has long meant professional ruin, yet some daring physicists, such as John Bell, David Bohm, and Hugh Everett, persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and the courageous scientists who dared to stand up for truth. "An excellent, accessible account." --Wall Street Journal "Splendid. . . . Deeply detailed research, accompanied by charming anecdotes about the scientists." --Washington Post
