Hi. I am currently working through some math textbooks (calculus, linear algebra, differential equations) over the course of the next 2 years. I work at a hedge fund now trading derivatives, and although the type of trading I do does not use mathematical modeling, I want to be able to enhance my production by trading options using these maths. However, I also want to learn physics when I am done with this because it is interesting to me and I know several traders who use principles of physics in their trading. Anyway I need a suggestion for best textbook to start with. I have constantly heard three recommendations: 1) Conceptual Physics by Hewitt. From what I hear it is good for concepts but severly lacking in math, which is pointless. So, is it worth reading this book just because it helps conceptually? Or would an intro book with more math also help with the fundamentals conceptually? Like, should I read this book plus a beginner book with math? I don't want to have to read two 700 page books that both say the same thing. 2) Physics by Halliday and Resnik. Does it do a good job explaining the concepts, on top of the math? Or should I also read the hewitt book? 3) 3 volume Feynman lectures. I heard these are like the best books ever for physics. However, some say they are not for physics beginners. Should I read the Halliday book first, plus some other basic physics books, before reading Feynman lecture? I have no problem spending a few years teaching myself various branches of physics for fun and to add to my trading. But I do not like to waste time, and don't want to read the same concepts in 10 different books if I dont have to.
