Hi! It's Christmas, and I got a pretty hefty sum of money from my family. Guess what I plan to do with it?=> Buy physics books of course! I'm so excited, I never really had enough money to buy the classic physics books I wanted, and now, I am left with a very difficult choice. I am a prospective physics major, and am enrolled in both Physics C and Calculus BC, but I also am studying differential equations and Calc III at home. Keep in mind that I'll buy a book for physics self study, so I won't have a teacher to guide me or solve problems for me. My goal is to ace my 1st year physics class in college, as well as gain a strong understanding and flexible problems solving skills (the kind of skills that would be needed to do Olympiad level physics for example). I am probably going to enroll in a course equivalent to 8.012 at MIT, a course that uses Kleppner and Kolenkow and Purcell. I already am using an intro book in physics C, which is Physics by Scientists and engineers by Paul A. Tipler. As far as my credentials are concerned, I can solve most problems in Halliday resnick and tipler (there is 1-3 problems every chapter I can't solve). I have narrowed my choices to the following: - Feynman's physics lectures (vol.I-III): I'm slightly concerned that this book will give me only superficial understanding b/c of the lack of practice exercises and mostly theory coverage. - Introduction to Classical Mechanics by David Morin:I'm concerned this book is too advanced for me and will discourage me. - Irodov problems in general physics - Introduction to Mechanics by Kleppner and Kolenkow Both Irodov and K.&K. don't have solution manuals, which kind of sucks because I most probably can't solve all the problems. How would you describe the difference between Irodov and K.&K. problems? Are they about the same difficulty level? Unfortunately, I don't have enough money to buy all of them , I can only buy one of them. Which one would you recommend me, knowing my goals and aspirations? Thanks so much!
