A good major

There are a lot of major/areas of study that I don’t really know about. I’m interested in science/tech and also politics/law, but I also have an visual arts background that I’d like to use to my advantage. They’re pretty unrelated, but I was wondering if there were things that are related to all three.

I think you need to pick 2…you could major in engineering and then go to law school and become a patent attorney.
You could do industrial design (STEM + art)

You have a lot of time to figure this out. For many or most students the first couple of years of university requires taking introductory classes in multiple different subjects. However, students usually come in to university with a “STEM” or “humanities” or ??? concentration.

I certainly know people who did undergrad in engineering and then went to law school.
