My computer science degree required 4 terms of calculus, 2 terms of linear algebra, 2 terms of differential equations, 4 terms of physics and 2 terms of statistics. I think that was all of it. I also took a nuclear physics course that was quite interesting. The diff equations were part of the electrical engineering minor.
Didn't really do much with astronomy so I really don't quite get how they figured out the distance to the sun. But I thought it was interesting as is the book 'sapiens'. https://www.amazon.com/Sapiens-Humankind-Yuval-Noah-Harari/dp/0062316095 Oh and I remember almost none of all that math. Too long ago.
