I'm writing a story that involves a two-person team inventing and building a time machine. Essentially, Character #1 is the "big idea" type (comes up with the theory) and Character #2 does the more practical, detail work (creating and fine tuning the machine itself). If this were to happen in real life... what sort of backgrounds would these two people need to have? I've been thinking probably #1 would have a background in theoretical physics and #2 would have studied applied physics or possibly some type of engineering... but I'd love some insight from people who know the disciplines better than I do. Thanks for any insight!
