Jimena Canales

""The Physicist and the Philosopher" explores the nature of time, the meaning of relativity, and the place of philosophical thought in a scientific age. Canales aims to reposition Einstein's work in a field of disputation and give Bergson back the significance he had in his contemporaries' minds."--Cathryn Carson, University of California, Berkeley "Like a stone cast on still waters, the Einstein-Bergson debate on the nature of time set off ever-widening ripples in physics and philosophy, but also in art, politics, and religion. In this fascinating book, Canales has written a kind of alternative intellectual history of the interwar decades of the twentieth century, one full of color and improbable conjunctions of people and ideas."--Lorraine Daston, Max Planck Institute for the History of Science, Berlin "Is time too important to be left to the physicists and their measuring devices? That was the issue at stake in a 1922 debate between Albert Einstein and philosopher Henri Bergson, celebrated at the time and wonderfully recovered in Jimena Canales s new book. A fascinating look at a pivotal moment in how we think about one of the most fundamental features of the universe."--Sean Carroll, author of "From Eternity to Here: The Quest for the Ultimate Theory of Time" "Sometimes past battles have repercussions that resonate long after memories have faded. In dramatic fashion, Jimena Canales demonstrates how a seemingly forgotten debate between Einstein and Bergson about the enigma of time changed the course of intellectual history."--Palle Yourgrau, Brandeis University "Whether readers side with Einstein s physics or Bergson s philosophy isn t the most important thing: this book opens up new ways of thinking about the relationship between science and the humanities that unsettle both."--Gerald Holton, Harvard University "This exciting, hugely interesting book opens out from a short but critical encounter between the philosopher Henri Bergson and the physicist Albert Einstein to consider their philosophies and the effects of their argument on the modern idea of time. Canales turns what is at first sight a limited debate into a major transatlantic encounter of profound implications. Well-researched, well-argued, and elegant, "The Physicist and the Philosopher" is a first-rate work of scholarship."--Stefanos Geroulanos, New York University ""The Physicist and the Philosopher" is a lively and engaging account of the meaning of time in the twentieth century. Canales uses the 1922 debate between Albert Einstein and Henri Bergson as a starting point from which to discuss an astonishing array of thinkers, technologies, and cultural developments. The book is an innovative, rich, and almost encyclopedic exploration of a crucially important question."--Edward Baring, author of "The Young Derrida and French Philosophy, 1945 1968""

Einstein, Bergson, and the Debate That Changed Our Understanding of Time

The Physicist and the Philosopher

A History

A Tenth of a Second

How scientists through the ages have conducted thought experiments using imaginary entities—demons—to test the laws of nature and push the frontiers of what is possible Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischievously materialized in the scientific imagination itself. Scientists began to employ hypothetical beings to perform certain roles in thought experiments—experiments that can only be done in the imagination—and these impish assistants helped scientists achieve major breakthroughs that pushed forward the frontiers of science and technology. Spanning four centuries of discovery—from René Descartes, whose demon could hijack sensorial reality, to James Clerk Maxwell, whose molecular-sized demon deftly broke the second law of thermodynamics, to Darwin, Einstein, Feynman, and beyond—Jimena Canales tells a shadow history of science and the demons that bedevil it. She reveals how the greatest scientific thinkers used demons to explore problems, test the limits of what is possible, and better understand nature. Their imaginary familiars helped unlock the secrets of entropy, heredity, relativity, quantum mechanics, and other scientific wonders—and continue to inspire breakthroughs in the realms of computer science, artificial intelligence, and economics today. The world may no longer be haunted as it once was, but the demons of the scientific imagination are alive and well, continuing to play a vital role in scientists' efforts to explore the unknown and make the impossible real.

Physicist and the Philosopher (eGalley)

Albert Einstein (1879-1955) was born in Ulm in the German Empire and received his academic teaching diploma from the Swiss Federal Polytechnic School in 1900. Unable to secure a teaching post, he eventually found work in the Swiss Patent Office in Bern, where he began to develop his special theory of relativity. In 1905 (his “miracle year”), he published four revolutionary papers, which came to be recognized as stunning breakthroughs in physics. For the next 25 years, while continuing his research, he taught at several universities in Europe, relocating to the U.S. in 1933, when Adolf Hitler came to power. During World War II, his insights regarding mass-energy equivalence led to the development of the atomic bomb, a practical demonstration of his theories that shook the world. Einstein was horrified that the bomb was used, and he spent the rest of his life warning about the dangers of nuclear weapons and advocating for peace and international cooperation. In Simply Einstein, Professor Jimena Canales offers the reader a unique perspective on the man who occupies a singular place in the popular imagination. Unlike many Einstein biographies, her book does not glorify the scientist or get lost in esoteric details, but takes pains to present a straightforward, thoroughly readable introduction to the man and his work that shows just how and why an eccentric physicist became a household name. The universe that Einstein described is the one in which we now live, a world of paradoxes and uncertainty, as well as infinite possibility. For anyone interested in better understanding how this came to be–and in gaining a fuller appreciation of the brilliant, flawed human being who changed everything–Simply Einstein is essential reading.

Simply Einstein

In the late fifteenth century, clocks acquired minute hands. A century later, second hands appeared. But it wasn’t until the 1850s that instruments could recognize a tenth of a second, and, once they did, the impact on modern science and society was profound. Revealing the history behind this infinitesimal interval, A Tenth of a Second sheds new light on modernity and illuminates the work of important thinkers of the last two centuries. Tracing debates about the nature of time, causality, and free will, as well as the introduction of modern technologies—telegraphy, photography, cinematography—Jimena Canales locates the reverberations of this “perceptual moment” throughout culture. Once scientists associated the tenth of a second with the speed of thought, they developed reaction time experiments with lasting implications for experimental psychology, physiology, and optics. Astronomers and physicists struggled to control the profound consequences of results that were a tenth of a second off. And references to the interval were part of a general inquiry into time, consciousness, and sensory experience that involved rethinking the contributions of Descartes and Kant. Considering its impact on much longer time periods and featuring appearances by Henri Bergson, Walter Benjamin, and Albert Einstein, among others, A Tenth of a Second is ultimately an important contribution to history and a novel perspective on modernity.
