Abstract
This paper analyzes the physics of the famous 1940 Frisch–Peierls memorandum, which examined the possibility of creating a nuclear weapon utilizing a fast-neutron chain reaction with uranium-235. While Frisch and Peierls’ estimate of the critical mass was far too low, their analysis was fundamentally sound. I also survey the role of the memorandum in the overall history of wartime nuclear developments, and its prescient predictions of aspects of the Cold War.
期刊介绍：
The purpose of this journal is to catalyse, foster, and disseminate an awareness and understanding of the historical development of ideas in contemporary physics, and more generally, ideas about how Nature works.
The scope explicitly includes:
- Contributions addressing the history of physics and of physical ideas and concepts, the interplay of physics and mathematics as well as the natural sciences, and the history and philosophy of sciences, together with discussions of experimental ideas and designs - inasmuch as they clearly relate, and preferably add, to the understanding of modern physics.
- Annotated and/or contextual translations of relevant foreign-language texts.
- Careful characterisations of old and/or abandoned ideas including past mistakes and false leads, thereby helping working physicists to assess how compelling contemporary ideas may turn out to be in future, i.e. with hindsight.
