If I become a physicist and got my Ph.D in physics can I work more experimentally and application based?
I recall hearing from professors that 50% of physics students want to be theoreticians, and only 5% of the jobs are in theoretical physics. So no, absolutely not. Theoretical physics doesn't have immediate practical use (though in the long term it may have enormous uses once it gets applied.) So there isn't a lot of money for it, the way there is money to get useful and desired things built that people will pay for. I think 50% of physicists are in academia and the other 50% are in industry. Anyone want to improve my numbers?
