Fiction vs. Nonfiction

I don’t see any difference, from a technical point of view, between writing fiction and writing nonfiction. The only difference is that with nonfiction, every fact in the book must refer to a document or a source outside of the book. But technically speaking, as a piece of work, the two have very similar requirements. When I wrote The Making of the Atomic Bomb, I tried to arrange the story so that it was dramatic and interesting, which it is inherently. There are some things in the book that a novelist might invent. I did not invent it, but I positioned it.
