I am currently about half way through the process of getting a physics degree (emphasized in cosmology) and a applied math degree (emphasized in quantum mechanics). Now my parents think that these two majors are useless in getting jobs, and wants me to study something that will help me get a job quickly after graduation. In the end as a compromise, I added a computer science minor to my course plan. So my question is; 1. If you are studying something that does not yet have many real life applications (like cosmology and quantum mechanics), do you have to go to grad school if you want a career that's related to those fields? 2. In case I couldn't go to grad school and need a job to survive, how much would the computer science minor help?
