The Martian probably needs very little introduction, since you're all huge nerds and the movie was a pretty faithful adaptation overall. Much of it seems to revolve around potatoes and how they're grown and what they taste like and if you can actually live solely upon them for any length of time. Troutman Fun Fact: I think potatoes are kinda garbage. Unless they're french fries. Or potato chips. But not plain potato chips. Those are also garbage. Look, I have opinions about potatoes, alright?
