The 9arm video uses the film Oppenheimer as a starting point for discussing the Manhattan Project during World War II. The project brought together scientists and government organizations to develop nuclear weapons; the story highlights the scale of the work and coordination across disciplines rather than the work of one person alone.
Trinity and its consequences
The US National Park Service records the Trinity test on 16 July 1945 in New Mexico as the world’s first nuclear-device test. Its history includes scientific development, decisions made during wartime and the impact on people near or downwind of radioactive fallout.
Understanding nuclear weapons requires attention to historical context, civilian harm and the responsibility of those who develop them. This article is a historical overview, not a technical guide.
