I've never seen the movie myself, but from what I understand there isn't any dialogue saying it's the Illiad. He gives her a book and she says it's a signed first edition without either acknowledging what book it is, but you can tell from the cover. My guess is the props department just gave them a random book without considering the book they gave them doesn't make sense in context.
It's kind of shocking, after a lifetime of assuming electrons whiz through wires at the speed of light, to find out they move so slowly that the speed at which they move is referred to as "electron drift."
