I like good Sci-Fi. By good, I prefer people who work out the math, like Heinlein, who spent a week calculating geo-stationary orbit. Or Asimov with the robot short stories, where you have to deduce the issue with the change in the three laws.

The Martian (thanks to you guys here!) fits in this. So does the Expanse series.

I've begun reading "Saturn Run". Seems, so far, to fit in with the above end of the Sci-Fi.

Any other suggestions in this direction? it is tough finding really good, scientifically accurate stuff out there.
