Due to the suggestion by Crosson, I'm making another thread. Basically, I'm curious what I can do to study physics and anything else I might need in highschool. Science Courses I've Completed: -Physical Science ( elementary Chemistry + newtonian Physics basically) -Biology -Chemistry -NJROTC Physical Sciences (Dealt with Electricity, motion, buoyancy, etc. Anything useful for the Navy) Mathematics Courses I've Completed -Algebra I -Algebra II (I want to say it included statistics) -Geometry (included some trig) Relevant Courses I'll be taking for my Junior year: -AP Biology -Pre-Calculus Basically, I have a pretty good understanding of Newtonian physics. I still haven't memorized all the formulas. I've read a good bit on General relativity and special relativity, but I wouldn't mind reviewing it. I've seen stuff about string-theory and M-theory on the Science Channel. No real formal study in it. The mental aspect of physics (understanding how things are) is easy for me. I have zero problem wrapping my mind around the actual concepts. I understand red shift, etc. I'm pretty familiar with "big bang" concepts. I understand black holes somewhat. I'm rusty on all of my physics knowledge however, and I don't have the mathematical knowledge to jump straight into graduate level work. So, any help in teaching myself more Physics, biology, and calculus would be greatly appreciated. However, my worst problem is I don't know what I don't know yet. So I have no clue what I understand compared to all the information available. Thanks for any help. EDIT: I'm also extremely familiar with entropy.
