Before I start, I know that no one other than myself can provide me with an ultimate answer. The reasons for this posts are to find any advice and recommendations, and also just to vent some of my worries. In a couple of weeks I will be registering for my second year courses as an undergrad. I just finished my freshman year in physics that I enjoyed a lot; however, at the start of the fall term i found out about this program in geophysics that I had never heard of before. Growing up in a quite seismic area as Italy, I had always been interested in reading or watching documentaries about earthquakes, volcanic activity, formation of mountains and geology in general. Since I moved to Canada a few years ago, this interest died down a bit, also because geology is never taught and barely mentioned in high school. Still, I ended up taking an intro course in geology during the fall that I really loved. So, after "inviting myself" to a couple of lectures in the 2nd year Exploration Geophysics course, I figured this would the perfect combination of my two favourite areas of science. After a few months spent going up and down to the offices of the departments of physics and geoscience to fix some mainly bureaucratic issues (the physics courses I took were not the ones required in 1st year of the geophysics program, and were also anti-requisites to the physics courses required in 2nd year of geophysics), here I am ready almost ready to pick my courses. And of course, it's now that I start doubting my decision. "Is this REALLY the right program for me? What if I don't like it? What if it really isn't what I imagined it would be?" and similar questions keep popping up in my head. Also, "What about all the things I will miss out from not pursuing a physics major?" One of the major reasons why I chose physics is because of my fascination for nuclear physics, relativity and quantum mechanics, but then I rationalize that this fascination is not due to any real interest in these subjects, but rather because i know almost nothing about them. Ugh! As well, I can't ignore the more practical and financial side of things. The economy of my province, Alberta, is largely based on the oil and gas industry. According to the Alberta Learning Information Services, 93% of "Geologists, Geochemists and Geophysicists" work in the Mining and Oil and Gas Extraction or Professional, Scientific and Technical Services industries. Needless to say, the pay is very good. Also, by talking to some students finishing their degree, geophysicists are quite in demand and companies will often finance grad students taking a master program, provided they will work for them after. While this may sound all great, my worry is that this may be a gift and a curse type of thing. Having an entire profession stand on a single industry is not ideal to say the least, especially when it's as unstable as the oil and gas one. On another hand, it seems that the only way to hope to find a job as a professional physicist is to have at least a M.Sc. in physics or similar. I am aware that a degree in physics can get you a job in the most disparate fields, but if I really wanted to work at a bank or a law firm, I would probably study something else. So, what's your advice? By the way, I wanted to thank everyone that contributes to this website, especially for the academic and career guidance sections. I just spent a few hours reading and learning info I otherwise would have never found out about or known when it was too late.
