It's good. Translation definitely could have been better. I don't know if the translator was bad in Polish or (and?) Russian, or didn't know anything about mathematical terminology, but it's the biggest detriment to the book. Reading more than a section at a time gets me the feeling you would likely get after hours of reading Wikipedia in Simple English. That's with what I'm dealing here.
Almost makes me wish I actually stuck with learning Russian. Almost.
It feels like a mockery after the night I had, but thank you.
