I have always seen these books in the stores, and such, and they're 100 on amazon (which is a heck of a lot better than B&N) and i want them, but then again they'll probably shoot right over my head. I'm working through my first year of high-school physics. I have read quite a few books on these topics though, im working through one on special relativity now. And i have also learned a little calculus and am trying to teach myself more and more of that as well. Will i be able to get some information from them? And then as i go on, and learn more (get into college and study physics and what-not) understand more? Is it a good investment i suppose is what i'm asking? Thanks!
