Aeronautical Science 101: the Development of Engineering Science in Aeronautical Engineering Education at the University of Minnesota
Aeronautical Science 101: The Development of Engineering Science in Aeronautical Engineering Education at the University of Minnesota A THESIS SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Amy Elizabeth Foster IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS October 2000 1. Introduction: Engineering Science and Its Role in Aeronautical Engineering Education In 1929, the University of Minnesota founded its Department of Aeronautical Engineering. John D. Akerman, the department head, developed the curriculum the previous year when aeronautical engineering was still an option for mechanical engineering students. Akerman envisioned the department's graduates finding positions as practical design engineers in industry. Therefore, he designed the curriculum with a practical perspective. However, with the rising complexity of aircraft through the 1930s, 40s, and 50s, engineering science grew more important to aeronautical engineering design practices than ever before. In 1948, the university closed a deal on an idle gunpowder plant. The aeronautical engineering department converted the site into a top- notch aeronautical research laboratory. A new dean for the engineering schools, Athelstan Spilhaus, arrived at the University of Minnesota in 1949. He brought a vision for science-based engineering. Akerman, who never felt completely comfortable with theoretical design methods, struggled with the integration of engineering science into his department's curriculum. Despite Akerman's resistance, engineering science eventually permeated the aeronautical engineering curriculum at Minnesota through this new lab and the dean's vision. In following this path, the University of Minnesota came to exemplify the significant place of engineering science in aeronautical engineering by the 1950s. -

I am a Special Agent of the Federal Bureau of Investigation (FBI) assigned to the Washington Field Office, and have been employed by the FBI for over eight years. I am assigned to a squad responsible for counterespionage matters including those relating to Cuba and matters involving the unauthorized disclosure of classified information. I have been working in this field since beginning my duties at the Washington Field Office. As a result of my involvement in espionage investigations and investigations involving the unauthorized disclosure of classified information, I am familiar with the tactics, methods, and techniques of particular United States persons who possess, or have possessed a United States government security clearance and who may choose to harm the United States by misusing their access to classified information. Further, I am familiar with the strategy, tactics, methods, tradecraft and techniques of the Cuban foreign intelligence service and its agents. Before working as a Special Agent for the FBI, I worked for eight years as an electrical engineer for the FBI. 2. As a federal agent, I am authorized to investigate violations of laws of the United States and to execute warrants issued under the authority of the United States.
