I have read about general relativity, quantum mechanics, and physics is general, but I'm looking for a book that goes a little bit more in depth with the math behind the theories (I understand a lot of those equations are going to be complicated). I'm in 10th grade so I'm doing Algebra II this year. I've also done a little bit a precalculus on my own. I'm guessing most books are going to require a certain level of proficiency in calculus, so I guess I'm looking for a book that will introduce me to the concepts while I work my way up to calculus. Most of what I have read has been in books that don't really give a mathematical explanation or on Wikipedia where some of the math is a bit over my head (I know Wikipedia is not always the most reliable source).
