I'm doing the Manhattan Project (which is sort of related) and have narrowed mine down to two areas:
The impact of the Manhattan Project on the scientific community
The various beliefs of the Manhattan Project scientists as to their moral responsibility regarding the bombing of Hiroshima
I've certainly found a lot to write about when the time comes to begin drafting my essay, and there have been a lot of books written about the subject.
I think the main question was whether it is the scientists' responsibility to control what their work is used for, or what technological advances take place because of it (eg. the Atom bomb)
