First and foremost, please excuse my English if there are any errors. I'm currently studying Biotechnology because ever since I was a kid being a doctor was always the one profession that has always interested me... But I'm also a sucker for technology and innovation. I'm 2 years into my major and I'm most likely going to change into the engineering field. I love math and physics and I've been working and debugging slot machines ever since I was 16 years old. I feel as if being an Engineer is what I was made for. But what kind of engineer? I like helping people and I love problem solving. Complex things interest me like no other, perhaps this is why I want to become a doctor. But physics and math has always been the other side of my pornography, in the sense of problem solving. I'm extremely fascinated with problem solving and math. Moving on... I like computers, and hardware devices and I would like to explore more into that field to create my own devices, not just for one specific concentration but for a very wide range of options. In short, an inventor. I like the way how Plasma and LCD monitors work, I love the idea of wireless connections, blu-ray disks, satellites, speakers, cell phones, pretty much every electrical device. and It has always been my dream to invent or to improve something so useful in modern society. My question here is, if I wanted to create such a thing, which type of engineering would I have to look into and which other sub-profession would be best to match my demands? Perhaps a combination of Physics and Electrical Engineering or Computer Science and EE? Any advice will be greatly appreciated.
