I'm fascinated by the project that led to the making of the atomic bomb. Not because of the technicalities - my understanding of physics (even now) is far too limited to really understand what they did back then. No, I'm interested in the the collective effort by such a heterogeneous group of geniuses that took place in that era. I'm interested in Szilard's early vision; in the - magical - leadership of Robert Oppenheimer that focused these people; in the little stories about the project - e.g. those in the Gleick's biography of Richard P. Feynman; in the aftermath, where Oppenheimer was "robbed" of his security clearance, partially by Teller's doing.
Here are some links I've come across.
