I've always been interested in math and science, and yet high school seemed to kill that interest for me...I'm a smart person, and the stuff in high school was pretty easy. I went through 4 years of high school with hardly a single challenge, or any real work done, because it was so easy for me to slack off and still get good grades, so I taught myself how to be lazy.
One thing is just that I had very few teachers who seemed to be both competent and enthusiastic/interested in what they were teaching. The few classes where I had good teachers, of course turned out to be my favorite classes. I am pretty good at math, but never put any effort in during high school because the way they approached it simply bored me. I am interested in lots of topics in biology, physics, and chemistry. I signed up for a physics class in high school, and got an entire semester of this teacher on the brink of retirement who talked about nothing but car racing and computers...he didn't even check the problems on the tests that he gave until DURING the time we took the test. Almost every test we took he would pipe up half way through "cross out numbers 10, 12, and 9, they can't be solved" or something else. After that class I never really thought much about physics again until recently.
I started reading a few things by Feynman, and also watching the Berkeley conceptual physics lectures on google...have been reading a pretty good (dated) conceptual physics book from my college's library. It's such a big difference when you actually learn the material from someone who 1) knows what they are talking about and 2) is genuinely interested in and excited about what they are teaching.
So I've been learning basics physics as much as I can on the side of my classes (currently at a community college, switched from a good university to save money as I had no clue what I was interested in after high school), as well as reviewing math, and thinking of majoring in physics now. I've always been naturally curious and interested in the everyday phenomena of just being alive and experiencing this ride of life. My main issue with college so far is that I am interested in so many things, I felt like choosing a major would limit my understanding of the world somehow. After spending lots of time reading topics in biology, chemistry, geology, social sciences, etc, physics seems to be the one field that is interesting, fun/exciting as well as innovative and important for the future, a worthwhile investment of my time, as well as possibly helping me to learn more about the physical world than any other subject.
One question. Does this lack of interest in physics make it easier for someone to be accepted into an undergrad physics major at a university, either out of high school or as a transfer? I looked up the statistics for the university I was previously at, which happens to be in the top 10 of physics programs nationally, and in a university with thousands of people, the number of physics majors was somewhere between 50-100 (closer to 50 if I recall correctly.)
One of my friends was accepted to the physics program here out of high school, with lower test scores than me, but pretty good grades I think. He ended up switching majors because he "would have failed out" if he had stayed in physics (yet he never really tried), and I suspect he mainly switched out because it would interfere with all of his partying. (frat boy now) It seems like physics and engineering intimidate people quite a bit. I think this fear has less to do with their actual ability to complete the work, but more with their motivation to actually have to work (and not be going out to bars 4 nights a week, etc.)
From what I have seen, college has just become an all-expense-paid 4 year vacation/party after high school...and you get a degree too! Not much of an actual education though. That doesn't happen until you decide that you really are interested in learning about things, and you decide to make the effort because you can't stand the idea of not learning.Sorry for the long post/rant.
