At the moment I am about to enter my final year of an MSci Physics with Particle Physics and Cosmolgy. My final year project will have me working on particle detector R&D (looking at designs and radiation hard technologies to upgrade LHCb's ECAL). The natural progression from that was to do a phd involving detector R&D, and up until a week ago that's what I had decided to do. I can't remember what happened but now I am not 100% that's what I want to do. I guess one of the reasons is because it is all computer work, and I have never wanted to have a computer based job. Some computing is fine (and inevitable) but I always imagined I'd get a more hands on job, being in a laboratory or doing fieldwork. So now I'm looking at alternatives. I understand that if I do decide to move away from particle physics that I will probably need to do another masters degree in the new subject. So I'm looking at careers that will let me travel lots, take measurements and/or install equipment. Anything hands on. I've considered geophysics as from what I understand it can involve a lot of fieldwork, even to remote locations like the antarctic. I was interested in volcanology as a child, however, looking at degree programs none of them are grabbing my interest. I've also considered aerospace engineering (more specifically astronautics and space science) as I'm very interested in space travel (the dream is to be an astronaut - extremely unlikely but I'm still going to take a stab at it) but from what I understand it's all computer work, you design the spacecraft/etc but you dont build it. So what careers have I not considered that would let me at the very least travel a bit, even if it still has a fair amount of computer work.
