Where Oppenheimer appears in your course
J. Robert Oppenheimer has a genuine claim on 1 lesson of the Pearson Edexcel International GCSE science course built into Incandio:
- Chain Reactions and Reactors — Physics: This page is about holding a chain reaction at exactly one neutron per fission, and Oppenheimer directed the project that deliberately did not. He is worth asking because he understood both the physics and what it would mean: he ran Los Alamos with complete commitment, watched the Trinity test, and then spent the rest of his career arguing against the weapons he had helped create, losing his security clearance for it in 1954. He is the right figure for the question a reactor page raises and cannot answer — what the difference between a power station and a bomb actually consists of, and who decides which gets built.
