Ok, here it goes. I graduated with a degree in math in 2010, and so far to now, I have been teaching chess, and math at college prep tutoring centers. I am interested in getting a job in physics, because I think physics is cool. My first question is: Do I need to go back to school, if I choose physics as a career. My second question is: If I do choose Physics, what sort of stuff can a person like me do? My prefer answer is that I can get a physics job by learning something myself, and putting it in my resume. My third question is: Out of curiosity, it seems to me that there is a oversupply/glut of PhD, and a lack of university position jobs. I would guess this also applies to physics, right. I am curious what exactly these people do if they fail to secure a job in universities?
