I've been researching different types of engineering and since some of them are pretty similar, I'm having trouble understanding the difference between them. Fields I'm looking into: Industrial engineering, systems engineering, manufacturing engineering, operations research, supply chain management (not sure if this is more business or engineering), operations management (more business than engineering?) If anybody has recommendations for what types might be a good fit for me, that would be great. A field that's relatively light on science would be nice-- I know that I am on physicsforums.com but to be honest, physics scares me. Last year (junior year) I took physics and it was definitely the hardest class I've ever taken. Maybe because it was supposed to be college level and I had never taken physics before? I managed an A- but that's basically because I could do the math without understanding what I was doing. AP Calc BC was a breeze and I enjoyed it, so a more math-heavy field is probably ideal. I know there is much harder math out there, but I'm sure there's also much harder physics. I'm the "big picture" type and designing more efficient processes interests me. I also like the human oriented aspect. Right now I'm helping design a cross country course-- creating a 3 mile path is trivial, the challenge is minimizing opportunities to get lost and/or cut the course and making it easy to follow with as few instructions as possible. Obviously this is a pretty minor "problem" but I like this type of thing. While taking my AP tests I was interested how they designed the grading process-- there are lots of numbers and codes to attach all of the documents to the person, the essay graders can't have any information about the identity of the person but the testing service still needs to be able to identify them, getting students to follow the instructions, preventing cheating, making sure that no tests get lost or are unidentifiable...etc. Designing a system/process like this appeals to me. Sorry for the long post! I appreciate any input you all have.
