Electromagnetic Radiation: Variational Methods, Waveguides and Accelerators

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.
