How the ordering of the sensible world continues to suggest a reality that no notes or letters can fully transcribe. An ancient tradition holds that Pythagoras discovered the secrets of harmony within a forge when he came across five men hammering with five hammers, producing a wondrous sound. Four of the five hammers stood in a marvelous set of proportions, harmonizing; but there was also a fifth hammer. Pythagoras saw and heard it, but he could not measure it; nor could he understand its discordant sound. Pythagoras therefore discarded it. What was this hammer, such that Pythagoras chose so decidedly to reject it? Since antiquity, "harmony" has been a name for more than a theory of musical sounds; it has offered a paradigm for the scientific understanding of the natural world. Nature, through harmony, has been transcribed in the ideal signs of mathematics. But, time and again, the transcription has run up against one fundamental limit: something in nature resists being written down, transcribed in a stable set of ideal elements. A fifth hammer, obstinately, continues to sound. In eight chapters, linked together as are the tones of a single scale, The Fifth Hammer explores the sounds and echoes of that troubling percussion as they make themselves felt on the most varied of attempts to understand and represent the natural world. From music to metaphysics, aesthetics to astronomy, and from Plato and Boethius to Kepler, Leibniz, and Kant, this book explores the ways in which the ordering of the sensible world has continued to suggest a reality that no notes or letters can fully transcribe.

From the bestselling author of Linchpin, Tribes, and The Dip comes an elegant little book that will inspire artists, writers, and entrepreneurs to stretch and commit to putting their best work out into the world. Creative work doesn't come with a guarantee. But there is a pattern to who succeeds and who doesn't. And engaging in the consistent practice of its pursuit is the best way forward. Based on the breakthrough Akimbo workshop pioneered by legendary author Seth Godin, The Practice will help you get unstuck and find the courage to make and share creative work. Godin insists that writer's block is a myth, that consistency is far more important than authenticity, and that experiencing the imposter syndrome is a sign that you're a well-adjusted human. Most of all, he shows you what it takes to turn your passion from a private distraction to a productive contribution, the one you've been seeking to share all along. With this book as your guide, you'll learn to dance with your fear. To take the risks worth taking. And to embrace the empathy required to make work that contributes with authenticity and joy.

A groundbreaking contribution to the history of the "long Civil Rights movement," Hammer and Hoe tells the story of how, during the 1930s and 40s, Communists took on Alabama's repressive, racist police state to fight for economic justice, civil and political rights, and racial equality. The Alabama Communist Party was made up of working people without a Euro-American radical political tradition: devoutly religious and semiliterate black laborers and sharecroppers, and a handful of whites, including unemployed industrial workers, housewives, youth, and renegade liberals. In this book, Robin D. G. Kelley reveals how the experiences and identities of these people from Alabama's farms, factories, mines, kitchens, and city streets shaped the Party's tactics and unique political culture. The result was a remarkably resilient movement forged in a racist world that had little tolerance for radicals. After discussing the book's origins and impact in a new preface written for this twenty-fifth-anniversary edition, Kelley reflects on what a militantly antiracist, radical movement in the heart of Dixie might teach contemporary social movements confronting rampant inequality, police violence, mass incarceration, and neoliberalism.

Religion and Technology into the Future: From Adam to Tomorrow’s Eve examines the broad significance of the current trends and accomplishments in technology (AI/robots) against the long history of the human imagination of making sentient beings. It seeks to enrich our understanding of the present as it is trending into the future against the richly relevant and surprisingly long past. Creatively considered in some depth are a wide range of specific examples drawn especially from contemporary film and television, as well as from cosmology, ancient mythology, biblical literature, classical literature, folklore, evolution, popular culture, technology, and futurist studies. This book is distinctive, in part, in drawing on a wide range of resources demonstrating the indispensable interrelationship among these disparate materials. Science, technology, economics, and philosophy are seamlessly interwoven with history, gender, culture, religion, literature, pop culture, art, and film. Written for general as well as academic readers, it offers fascinating and provocative insights into who we are and where we are going.

A wide-ranging exploration of how music has influenced science through the ages, from fifteenth-century cosmology to twentieth-century string theory. In the natural science of ancient Greece, music formed the meeting place between numbers and perception; for the next two millennia, Pesic tells us in Music and the Making of Modern Science, “liberal education” connected music with arithmetic, geometry, and astronomy within a fourfold study, the quadrivium. Peter Pesic argues provocatively that music has had a formative effect on the development of modern science—that music has been not just a charming accompaniment to thought but a conceptual force in its own right. Pesic explores a series of episodes in which music influenced science, moments in which prior developments in music arguably affected subsequent aspects of natural science. He describes encounters between harmony and fifteenth-century cosmological controversies, between musical initiatives and irrational numbers, between vibrating bodies and the emergent electromagnetism. He offers lively accounts of how Newton applied the musical scale to define the colors in the spectrum; how Euler and others applied musical ideas to develop the wave theory of light; and how a harmonium prepared Max Planck to find a quantum theory that reengaged the mathematics of vibration. Taken together, these cases document the peculiar power of music—its autonomous force as a stream of experience, capable of stimulating insights different from those mediated by the verbal and the visual. An innovative e-book edition available for iOS devices will allow sound examples to be played by a touch and shows the score in a moving line.

The Bright and the Good examines the connection between intellectual and moral virtues both through the history of philosophy and as it can be illustrated in comprehensive examinations of specific virtues. The first part of the book investigates the original assumptions posited by Ancient Western philosophers concerning the apparent connection between moral and intellectual virtues. The second part follows the assumptions through history from the Medieval and Modern periods of philosophy, noting how the assumption has been tweaked to accommodate specific ideological and scientific precepts. The third part showcases inquiries into specific virtues, taking the reader on an investigation unfettered by any specific time period or ideology so as to consider the apparent connection between the moral and the intellectual on a case-by-case basis. These essays relate both historical context and contemporary concerns and examine topics including vice, ignorance, hope, courage, patience, justice and mercy.
