Name- said:
I want to become a theoretical physicist and work on string theory and quantum mechanics and stuff like that but I don't know how. Should I go to a high rated school or just the oridinary? I don't need to get paid a lot but I would like to get atleast the average(not sure what that is) but since i enjoy physics the paycheck doesn't matter(The question is how much does a theoretical physicist make). What does a theoretical physicist do daily compared to other physicist(s)? and I have a few more questions but i'll refrain from asking (right now).
Im new to this forum and I am not sure if I posted this right or anything so if I am doing anything wrong just tell me. Anyways I put the prefix other because I am not sure what to take since I talk about more than one subject here.
OK, first of all, you never mentioned why you want to do string theory and QM and your experience with them. So I'll just assume the usual: you have read some popular science books on theoretical physics and are deeply touched by it. Good, but it is vital to know that whatever is portrayed in those books is highly misleading and even wrong. The world of theoretical physics is intensely competitive and difficult. It is NOT AT ALL what is described in the popular media. Only a very small subset of physicists deal with black holes and wormholes. An even smaller subset deals with time travel and other fun issues. Quantum mechanics is a very mathematical theory. In fact, one could say that it is only math. There is very little actual physics and philosophy involved (I know this is a very strong statement, and I'm sure people will disagree vehemently with this, but I stand by it).
So you want to be a theoretical physicist? Well, you should know that nobody hires theoretical physicists, except universities. So you'll have to go for a professorship. Getting a professorship is INSANELY hard. In fact, less than 1 in 10 PhD's eventually land a professorship! Only a very small fraction of undergrads eventually get a PhD. So the numbers are really against you.
Note also that if you end up with a bachelors in physics (that is: if you can't get into grad school (which happens a lot!), or if you don't want to go to grad school), then you have a useless degree. You'll find it very very difficult to get a job with this.
Am I telling you all of this to make you feel bad? No. If you want to go into theoretical physics, fine. But you should do it for the right reasons, and while being aware of all the caveats.
So what do I advise you? First, get actual math and physics books. Learn calculus, learn physics from those books. Do NOT learn them from watching videos, even if it is from MIT OCW or Khan Academy. The idea is to get a very realistic idea of what studying physics is like. And for that you need to go to actual dry books, read through them and work through all the problems. If you still enjoy physics this way, then you might want to think about doing a bachelors in physics. We can recommend you books if you want, but then you need to tell us your background in both math and physics.
If you do end up doing a bachelors in physics, make sure that you're taking courses that make you employable. For example, this could be a dual major in computer science or engineering. Or this could be simply some programming courses. Anything that could give you an edge.
Be sure to always have a plan B ready. Always. The chances of you dropping out for whatever reason are great. Make sure not to neglect a plan B in case you do drop out.
