FYI, Fluid dynamics is some hard fuckin’ shit. It’s the modelling of fluid substances, like air or water. It’s complex. It’s got a lot of coefficients, a lot of calculus. I met a kid who coded modelling systems for submarine hulls once, at some conference. The guy was so smart he didn’t even seem like he was part of this world, I couldn’t even talk to him. I didn’t have the vocabulary or whatever. He just drifted around like a ghost. He was deep in military research, spent the whole show being followed around by this bulky looking bodyguard. I think he was meant to be acting as an anchor, to stop the kid getting caught up in a strong breeze and floating away.
