What I really want to do is make films, make music, and study the social lives of animals... those are all things you would learn in a fine arts degree. I still need all those science courses to make unique technologies for my unique creative endeavors. Can I bake my cake and decorate it too? I think music is the most difficult thing for me to master as a career without a piece of paper saying I am a musician. Sure I can play beautiful music but people with money to invest don't know if it is good music or not. Duel degrees have lots of cross-over courses making for a much more impressive resume with a lot less extra work.
