@Simus,
Quote:I dont know where to start
Are you already familiar with calculus, and classical physics (mechanics, waves, thermodynamics, electromagnetism, and special relativity)?
That's where I would start to get some background on the subject. I am sure if you search around you can find a good txt book (there are calc based physics books and algebra based physics book; pick a book based on your math comprehension). Also look into Khan Academy, there are lot of helpful videos on the subject (math and physics).
Quantum physics requires a good grasp of advanced mathematics, so it's good to brush up on your math skills while dabbling in classical physics.
