The usefulness of electrical engineering's approach to electromagnetic problems also noted by other physicists like Robert Dicke and more specially Julian Schwinger. Schwinger's emphasis on using electrical engineering's point of view was even more general than just in electromagnetic phenomena so that he argued for the use of engineering worldview even in pure branches of physics like high-energy physics. Schwinger also said about his transformation from a person who saw electrical engineering problems as a pure physicist to a person who saw pure physical problems as an electrical engineer: "I first approached radar problems as a nuclear physicist; soon I began to think of nuclear physics in the language of electrical engineering."
