What could quantum mechanics have in common with the philosophical musings of the ancient Greeks? French physicists Etienne Klein and Marc Lachieze-Rey see an unbroken thread running from antiquity to the present - an ongoing search, throughout the history of science, for unity. In The Search for Unity the authors reveal how the quest for the One has driven all the great breakthroughs in science. They show how the Greeks searched for the fundamental element in all things; how Galileo unified the earth with the heavens, by discovering valleys and mountains on the moon; and how Newton created a single theory to describe the motion of the celestial bodies. Throughout the book, the authors stress the esthetic motives of scientists, how they recognize truth through apprehension of mathematical beauty. And in tracing the quest for unity up to the present day, they illuminate the bizarre workings of quantum mechanics and the sticky definition of reality itself at the subatomic level.
Contains revelations on how the quest for unity has driven all the great breakthroughs in science and shows how the Greeks searched for the fundamental element in all things.
As World War II wound down and it became increasingly clear that the Allies would emerge victorious, Albert Einstein invited three close friends—all titans of contemporary science and philosophy—to his home at 112 Mercer Street in Princeton, New Jersey, to discuss what they loved best—science and philosophy. His guests were the legendary philosopher and pacifist, Bertrand Russell; the boy wonder of quantum physics, Wolfgang Pauli; and the brilliant logician, Kurt Gödel. Their casual meetings took place far from the horrific battlefields of the war and the (then) secret lair of experimental atomic physicists in Los Alamos, New Mexico. Using these historic meetings as his launching pad, Feldman sketches the lives and contributions of the four friends, colleagues, and rivals—especially Einstein, innately self-confident but frustrated in his attempt to come up with a unified theory, and the aristocratic but self-doubting Lord Russell. Masterfully researched, this book accessibly illuminates the feelings of these notable men about the world of science that was then beginning to pass them by, and about the dawning atomic age that terrified them all.
This book revisits Einstein’s postulate of the invariance of the speed of light, focusing on the corresponding train thought experiment. It shows how a close analysis of the supposed relativity of the simultaneity of light beam emissions brings us to the principle of the relativity of simultaneity at the physical level. However, in the objection about a spacecraft and a missile presented here, this principle turns out to be self-contradictory. The present logical and mathematical considerations are liable to challenge the validity of the second postulate of Special Relativity. Recognition of the results of this analysis could revolutionize our conception of spacetime.
How to use philosophy and music to open your horizons and enjoy being yourself, put theory to work, and help you experience personal growth is discussed in A Marriage of Philosophy and Music. It is all about "after." After having a liberal education, you are comfortable in modern culture, and after further education and becoming a specialist in some field, you enjoy using your skills. We learn the ideas and methods of many social cultures and our own chosen specialty, but we often neglect the liberal art of disciplining and enjoying the ideas and methods of our own individuality. This book offers a path toward the education of privacy, with the key words being selection, design, and beauty. ...

Throughout history, the mysterious dark skies above us have inspired our imaginations in countless ways, influencing our endeavours in science and philosophy, religion, literature and art. Heavenly Treasures is a truly beautiful book showing the richness of astronomical theories and illustrations in Western civilization through the ages, exploring their evolution, and comparing ancient and modern throughout. From Greek verse, mediaeval manuscripts and Victorian poetry to spacecraft photographs and computer-generated star charts, the unprecedented wealth of these portrayals is quite breathtaking.
Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time.
