Introduction: Physics, Technology, and Technics during the Interwar Period

Area of Science:

• History of Science
• Physics History
• Quantum Mechanics History

Background:

• The 1920s-1930s saw major theoretical breakthroughs in quantum mechanics, expanding physics.
• Historical focus on quantum mechanics has overshadowed other factors driving physics expansion.
• World War II is often viewed as the pivotal moment for physics' industrial-scale engagement.

Purpose of the Study:

• To re-evaluate the historical narrative of physics expansion.
• To explore the role of interwar physics developments in preparing scientists for wartime and Cold War collaborations.
• To highlight underappreciated causes for the growth and societal integration of physics.

Main Methods:

• Historical analysis of scientific and governmental archives.
• Review of scholarly literature on the history of physics and World War II.
• Examination of the relationship between academic research and industrial/military applications.

Main Results:

• While quantum mechanics was a key development, it was not the sole driver of physics expansion.
• World War II significantly transformed physics through unprecedented government funding and military interests.
• Interwar physics advancements provided foundational knowledge and trained personnel crucial for wartime mobilization.

Conclusions:

• Developments in interwar physics, particularly quantum mechanics, unexpectedly prepared scientists for large-scale engagement with industry and government.
• The societal and technical integration of physics accelerated dramatically during World War II.
• A comprehensive understanding of physics' growth requires considering both theoretical advancements and external socio-political factors.
