Greetings Physics Forums! I am currently applying to universities here in the United States and have been fascinated with engineering, physics, and mathematics for years now. I love the idea of designing and building as an engineer, researching and discovering as a physicist and research as a mathematician. I have also recently come across the idea of a "slash career," where an individual possesses multiple careers and specializations. My question to you ladies and gentlemen, is how I might combine engineering, physics, and mathematics into one career or possibly allowing them to exist as multiple work oppurtunites at the same time. Any advice for an aspiring student will be very much appreciated!
