Hey, I haven't been here for awhile but I would like to know if anyone has some good links or free pdf books, to help me learn and excel in quantum physics and calc. I so far have not taken any calculus and it will most likely be completely foreign to me but, I understand that and since I'm working a hellishly physically demanding graveyard shift factory job I have a lot of free time on my hands outside of work and sleep. So first I would like to know.(I'll separate questions from text) --What should I learn 1st? I know some Quantum physics and some of the more accepted theory's and some of the less accepted ones. I mainly learned what I know now just to prove a friend wrong in a argument about Quantum physics. Also, so far the math I have encountered in physics hasn't really knocked my block off leaving me confused. In other words I have been able to figure out most equations with a pre calc education so far, but, I doubt that will continue. --What are good practice sites? --Where is a good place to start learning Quantum Physics? By this, I mean where exactly do I start what theory's would be best to start at? Because Quantum physics isn't like a history book or a math book that i can just read sequentially related parts, is it? To me Quantum physics seems like in order to understand something you need to know something and to fully grasp that something you need to know something else in which your research would actually end up teaching you more than lectures. So that is why I am asking generally where to start because once I start my own questions will lead me to other theory's and Quantum Physics discussions. thank you, that is basically all. On a side note do you believe Quantum Physics to be a form of modern Alchemy with all spiritual beliefs behind Alchemy beside? Edit:I was thinking I should start with classical physics and then work my way to wave particle duality, while simultaneously learning calc. (I think I found a online textbook that might help). And then read basic Quantum theory and break it down into the separate parts that it consist of and learn them individually. I also found a college recording class on youtube of intro. to QP. which seems nice.
