Hi, I need a little help. I'm 16 and few months ago started being interested in astronomy. I haven't made a big progress since then, because I don't know where to start. I'm quite good at maths, not so "strong" at physics, but I don't have lot of problems with this subject. What and where should I learn at first? (I started "brief history of time", found "crash course" and csuDH course, but didn't start them). My knowledge of astronomy is very very low, so I'd be thankful for your advice!
