In the history of the Manhattan Project, one name stands out for his decision to abandon it. Joseph Rotblat, Polish-British physicist, was the only scientist who left the program upon realizing that Nazi Germany was no longer a nuclear threat. His later life was dedicated to activism for disarmament and peace, an effort recognized with the Nobel Peace Prize in 1995.
From criticality calculations to scientific diplomacy 🕊️
In Los Alamos, Rotblat worked on applied nuclear physics problems, such as calculating the critical mass necessary for a chain reaction. His training allowed him to understand the destructive potential of the device under development. After his departure, he swapped the laboratory for diplomacy, founding the Pugwash Conferences. This forum used scientific rigor as a tool to build bridges of dialogue between opposing blocs during the Cold War, trying to contain the proliferation that he himself had helped make possible.
When the ethical bug is more critical than the technical one ⚠️
Imagine the scenario: you're in the most secret technological project, with unlimited resources and the world elite in your field. The deadline is the war and the release is the bomb. Suddenly, you realize that the main client (Nazi Germany) has canceled the order. Most continue programming. Rotblat, on the other hand, did a ctrl+alt+del on his participation. He chose to report a bug in the project's ethics, a gesture that doesn't usually appear in management manuals.
