Julian Schwinger byl americký fyzik, který se významně zapsal do oblasti kvantové elektrodynamiky. Jeho průlomové práce, zejména využití konceptů renormalizace hmotnosti a náboje, vyřešily rozpory mezi teoretickými předpověďmi a experimentálními daty, čímž zahájily novou éru v kvantové teorii pole. Schwingerův vliv na fyziku byl hluboký, a to jak prostřednictvím jeho vlastního výzkumu, tak jako mentora více než sedmdesáti doktorandů, z nichž mnozí se stali předními teoretiky své generace.
Julian Schwinger, who taught quantum mechanics at Harvard, aimed to write a textbook since the 1950s. Though he hesitated to publish his lecture notes, the lectures from Les Houches in 1955 were eventually released. The 1991 reissue includes a preface discussing the evolution of quantum kinematics and the importance of notation.
The book expands on Dr. Schwinger's earlier works by adding four new sections that delve deeper into topics related to electrodynamics. It builds upon previous discussions of the two-particle problem and explores applications in hydrogenic atoms, positronium, and muonium, providing a comprehensive understanding of these advanced concepts in theoretical physics.
Focusing on quantum electrodynamics, this first volume explores techniques that highlight the interconnectedness of high-energy particle physics with electrodynamics, gravitational theory, and many-particle cooperative phenomena. It showcases the foundational contributions of Julian Schwinger, a Nobel laureate, emphasizing his influence in the field. The book serves as an essential resource for understanding complex physical concepts and their relationships within advanced theoretical frameworks.
A Nobel Laureate relates the fascinating story of Einstein and the development of relativity theory. Perfect for readers without a scientific background, it discusses the meaning of time, gravity and its effect on light, non-Euclidean geometry and the curving of space-time, and more. 189 black-and-white illustrations.
The book showcases Schwinger's distinctive lecturing style, emphasizing a logical progression of concepts in classical electrodynamics. This anniversary edition refreshes the content while preserving the original voice and clarity of Schwinger's teachings, making it a valuable resource for students and enthusiasts of the subject.
Including Seminal Papers of Julian Schwinger
Set during World War II, the narrative explores Julian Schwinger's pivotal role at MIT's Radiation Laboratory, where he focused on radar technology rather than nuclear weapons. At just 25, he sought a less structured environment, contrasting with his previous experiences in more regimented settings. The lab's work on microwave technology was crucial for the war effort, showcasing Schwinger's iconoclastic approach and significant contributions to science. His decision to join the Rad Lab reflects his preference for impactful innovation over military applications of nuclear physics.
A concise treatment by the future winner of the 1965 Nobel Prize in Physics, this work was first published under the auspices of the United States Atomic Energy Commission in 1952
