I've seen a lot of people talking about how autistic-coded Grace is in the movie, but I have yet to see anybody mention how much deeper that autism runs in the book? Like the first two chapters are maybe like a page or two of Grace waking up and then the rest is just him calculating shit for no real reason.
Like he immediately is like "I need to figure out how much gravity I'm experiencing right now because it's really annoying me. Also I would like to know how big of a centrifuge I would have to be in in order to experience this level of gravity, and before you ask, yes, I showed my work. Let me explain, in way more detail than anyone could possibly want or need, my calculations." He literally admits he doesn't need to be doing all this math, he just really, really wants to.
And then when he tries to start communicating with Rocky, the first two things he brings are a clock and tape measure. So he can teach him about numbers. No hi, hello, how are you? I don't think they even got to 'yes' and 'no' before he pulled up trying to teach the alien how to count. This man is so obsessed with numbers, he cannot possibly conceive of an intelligent species that isn't just as obsessed with numbers.
