At this point I feel like my classical mechanics I course is an engineering course. While I do enjoy physics, I am much more interested in the theory behind it.. I find myself easily engulfed in calculus but when it comes to physics it is harder to motivate myself. I love proofs and mathematics, and physics is what actually got me started in appreciating mathematics itself. But at this point I completely hate the way that physics goes on to portray its concepts. I feel like a lot of things are left in obscurity. Its too much of a "hey lets use this, this, and this math formula and try our hardest to conceptualize the problem." I'm an aspiring physics PhD holder, but at this point classical mechanics I is really turning me off. Also keep in mind that I took physics in high school, so that may also affect my level of interest toward classical mechanics I. I say this especially because I have a midterm soon. I always find myself with the urge to open my calculus book and doing extra problems instead of opening up my physics book. That is certainly not good since I'm planning to pursue theoretical physics.. -_- How different is introductory physics to some of the higher level physics courses that you take later on? Will it be more theory or will problem-solving be stressed over theory for a while?
