Purdue University: Lecture Notes - "The Principles of Optics", 1943 - 1944

This series contains correspondence, reports, research notes and published works created by Fred and Maguerite Rogers created when they worked among specific organizations. Because the two worked as a team for much of their careers, no effort was made to separate these records and the records have been maintained in the Rogers' original order. Some of the subjects in this series include: Beta-particle decay, the fracture of metals, the United States Naval Ordiance Test Station, convection currents in porpus media, ballistics penetration and university research and coursework.
