I am 13 and have been reading non technical books/papers for about 8 months, stuff by Carl Sagan and Isaac Asimov etc. I have no trouble understanding them. But when I read any of the more technical books, I understand only about half of it. Do I not know enough math? I know the basics of calculus and anything below agebra 2 is as easy as PI. Do I need to know more? Or is it a problem with reading comprehension? Or am I just to young to be able to understand more technical books? Any comments would be helpful. Thanks, The kid who reads to much.
