Anderson talks almost exclusively about his work during the thirties with particles of high energy involved in nuclear reactions. He covers in detail his discovery of the positive electron, his pair production work with gamma rays, his expedition to Pike’s Peak with Neddermeyer and their discovery of the mesotron. He mentions that it was in his speech accepting the Nobel Prize in 1936 that he first mentioned the possibility of negative and positive particles of intermediate mass. After noting the absence of any cosmic ray work during the war years, he mentions the postwar development of cosmic ray work into high energy physics.
The interview focuses on Archambeau's geophysical training at the California Institute of Technology and his career as a seismologist, covering the period before 1970. Major emphasis lies on his involvement in issues related to the seismic detection of underground nuclear explosions and his advocacy for a nuclear test ban treaty. He discusses the Department of Defense's "Project Vela Uniform," which aimed at improving seismic detection capabilities, and he describes Vela's impact on his career on seismology in general.

This interview surveys Baum's career as a physicist at the Naval Research Laboratory (NRL) and astronomer at Mt. Wilson and Palomar Observatories. After sketching Baum's early life, the discussion concentrates on Baum's role in the development of spectroscopy research at NRL, specifically his work on the UV spectrum of the sun - including the first successful UV spectra of the sun. Aspects of his experience in experimentation with V-2s and Aerobees, and his thesis research on rockets at CALTECH (PhD, 1950, physics) are also explored. Additional topics discussed include: Optics Division, NRL; White Sands Proving Ground (NM); relationships with, and costs and descriptions of Baird Atomic; V-2 missile experiments, development and launch; meetings with Werner Von Braun; and contacts with R.W. Wood, J. Strong, Lyman, Stockbarger, and Tousey.
