I can see that! The physics and theoretical stuff only got really interesting for me when you hit the mathematician trying to quantitatively solve for the three-body problem and the last last chapter where you get to dimensional folding and unfolding; everything before that was pretty "I could know nothing about physics and just nod along."

The book being in translation is another thing: I read it having done a tiny bit of research/practical translation myself, and so I'm a lot more forgiving of the oddity of the language. Plus my background is in this sort of historical stuff, so it's an auto-win for me.

But definitely a book that you have to read the ABSOLUTE LAST CHAPTER OF to get why ANYTHING in the first n-1 chapters work...
