So, I'm writing a fic, and... I'm completely hopeless at anything sciencey. (Not that Stargate itself doesn't suck majorly at that, too, on occasion, but hey.) So, question, oh brainy ones:

What might MacGyver and geek!Sam need to work on together?

She's an astrophysicist, of course, and seems to be a bit of an engineer, and he's... well, done a lot of things. He seems to know stuff about chemistry, physics, nuclear physics... he helped to dismantle nuclear weapons, once lived in an observatory (verrrrry briefly, at the very start)... also knows stuff about forestry, conservation, and - well, pretty much anything. 

That was probably a massive display of my ignorance on such subjects, but Wikipedia is only so helpful.
