Julian Schwinger (1918-1994) was one of the giants of 20th Century science. He contributed to a broad range of topics in theoretical physics, ranging from classical electrodynamics to quantum mechanics, from nuclear physics through quantum electrodynamics to the general theory of quantum fields. Although his mathematical prowess was legendary, he was fundamentally a phenomenologist. He received many awards, including the first Einstein Prize in 1951, and the Nobel Prize in 1965, which he shared with Richard Feynman and Sin-itiro Tomonaga for the self-consistent formulation of quantum electrodynamics into a practical theory. His more than 70 doctoral students have played a decisive role in the development of science in the second half of this century.This important volume includes many of Schwinger's most important papers, on the above and other topics, such as the theory of angular momentum and the theory of many-body systems. The papers collected here continue to underlie much of the work done by theoretical physicists today.

The ideas at the root of quantum theory remain stubbornly, famously bizarre: a solid world reduced to puffs of probability; particles that tunnel through walls; cats suspended in zombielike states, neither alive nor dead; and twinned particles that share entangled fates. For more than a century, physicists have grappled with these conceptual uncertainties while enmeshed in the larger uncertainties of the social and political worlds around them, a time pocked by the rise of fascism, cataclysmic world wars, and a new nuclear age. In Quantum Legacies, David Kaiser introduces readers to iconic episodes in physicists’ still-unfolding quest to understand space, time, and matter at their most fundamental. In a series of vibrant essays, Kaiser takes us inside moments of discovery and debate among the great minds of the era—Albert Einstein, Erwin Schrödinger, Stephen Hawking, and many more who have indelibly shaped our understanding of nature—as they have tried to make sense of a messy world. Ranging across space and time, the episodes span the heady 1920s, the dark days of the 1930s, the turbulence of the Cold War, and the peculiar political realities that followed. In those eras as in our own, researchers’ ambition has often been to transcend the vagaries of here and now, to contribute lasting insights into how the world works that might reach beyond a given researcher’s limited view. In Quantum Legacies, Kaiser unveils the difficult and unsteady work required to forge some shared understanding between individuals and across generations, and in doing so, he illuminates the deep ties between scientific exploration and the human condition.

Quantum Macroeconomics presents a new paradigm in macroeconomic analysis initiated by Bernard Schmitt. It explains the historical origin, the analytical contents, and the actual relevance of this new paradigm, with respect to current major economic issues at national and international level. These issues concern both advanced and emerging market economies, referring to inflation, unemployment, financial instability, and economic crises. In the first part of this volume, leading scholars explain the historical origin and analytical content of quantum macroeconomics. The second part explores its relevance with respect to the current major economic issues such as the sovereign debt crisis and European monetary union. The volume also features two previously unpublished papers by Bernard Schmitt. The main findings of this book concern the need to go beyond agents’ behaviour to understand the structural origin of a variety of macroeconomic problems, notably, inflation, unemployment, financial instability, and economic crises. The originality that pervades all contributions is plain, when one considers the lack of any structural explanation of national and international economic disorders in the literature within the mainstream approach to economics. This edited volume is of great interest to those who study macroeconomics, monetary economics and money and banking.

This important volume describes the wide-ranging scientific activities of Léon Van Hove, through commentaries by his colleagues and a selection of his most influential papers and documents. The reprinted papers are grouped by topic, starting from his early work in mathematics and theoretical and statistical physics, up to his very last contributions in elementary particle physics and multiparticle dynamics. Van Hove's career as teacher, director and science advisor in many European institutions is presented in sketches by friends and coworkers. A selection of his speeches and documented thoughts on science completes the volume.

"Quantum Mythology: How Physics Shapes Our Myths and Legends" explores the intriguing connections between quantum mechanics and ancient myths, suggesting that many legends may have been early interpretations of phenomena now understood through quantum principles, bridging the gap between science and mythology. The driving idea behind the book "Quantum Mythology: How Physics Shapes Our Myths And Legends" is to explore the intricate interplay between mythology and quantum theory. The book aims to demonstrate how ancient wisdom and modern quantum concepts are interconnected, presenting a narrative that intertwines human imagination with the realities of quantum mechanics. By examining phenomena such as wave-particle duality, entanglement, and superposition through the lens of mythology and mysticism, the book seeks to offer a profound understanding of how physics shapes our myths and legends and to reframe our perception of nature and reality. Key Takeaways The concept of quantum mythology integrates ancient myths with quantum mechanics to reveal fundamental truths about existence. Quantum mechanics phenomena such as superposition, entanglement, and wave-particle duality mirror themes found in global mythologies. Ancient myths often depicted cosmic creation, interconnectedness, and non-locality, which resonate with modern quantum theories. The interdisciplinary approach fosters a holistic understanding of reality, blending empirical science with symbolic mythological interpretations. The integration of quantum principles with mythology prompts a reevaluation of time, space, consciousness, and reality itself. This synthesis has practical implications for technology, such as quantum computing and communication, as well as cultural and ethical considerations. Preserving and revitalizing ancient myths through the lens of quantum mechanics can promote cultural appreciation and global unity.
