I'm a practicing physicist, so I'll give a bit of advice. The only reason to go into physics is because you love doing it--but--you have to go into with your eyes open. The job market is extremely competitive these days for faculty and national lab positions. Depending on your subfield, there may or may not be industry jobs. If you're not having fun and you finish, then what are your options: 1) Medical Physics 2) Wall Street (though I hear that it's getting harder to go directly from physics phD to wall street and more people are getting a masters in financial engineering first) 3) Software 4) Management Consulting 5) Science Policy 6) Etc. While the salary for all of these can be good, you have to look at the opportunity cost--you're looking at ~6 years for grad. school. Someone else might be able to tell you if it's worth sticking around to pick up either your masters in physics (or to take some graduate courses in CS)--but if you don't love it, my advice is to get out and do something that you're passionate about--What do you mean by SV type stuff? Now, with all that having been said--one thing you might want to consider is that the first year of a typical physics grad. student is fairly hard with coursework and such and you might want to try to pass quals. and try research for a year before making your final decision--are you interested in theory or experiment? Did you do research in undergrad.? Life in a lab can be rather different from coursework--also, even course work tends to be more interested in advanced courses such as GR, Quantum Field Theory, etc. than in the typical Jackson courses.... Good luck!

> SV type stuff? I was being purposefully vague--I just meant the Silicon Valley scene. I have a college friend who just got a cool job there, and some family friends, too. It sounds like a fun place from the culture side, but also from the technology side--specifically, I'm amazed by what a small team can do in a 48-hour hackathon with today's technology. The one that comes to mind is that "Infinite Scrabble MMO" from about 18 months ago. 150 man-hours can produce that? Wow. I did research in undergrad (mostly over the summers, but a bit during the year). I had a lot of fun, and it was motivating work. But it was programming work! I wrote a bunch of data analysis code and did a little bit of GEANT simulation stuff, and it all felt more like programming than physics. And the "physics research" (experimentalists) that I have seen looks more like engineering (designing/building some apparatus, then fixing all of the problems...). It just seems so slow-moving compared to the software industry. There's a lot less room for individualism, and it feels like you've got a lot of really smart people doing a lot of menial, commodity tasks (I'm thinking of every PhD candidate and postdoc I've ever known). I'll have to give theory a closer look. It's hard to see myself in it any time soon, because there's more material I'd need to learn first. (I think I'm rambling to myself now.) All this, I think, is to say that I'm pretty sure the physics charm has worn off. Unless there's something really exciting around the corner, I think I'm over it. I seem to have written this comment as if there's some point I'm trying to prove. Habit. Sorry about that! Thanks for the advice and encouragement, and I'll keep my eyes open!

  Hi Joe, In general, there's a certain amount of tedium in any endeavor. During my PhD, I did some work on synthesis--it was fun to try to figure out how to realize some properties in a new material--to try to figure out synthesis challenges--the actual sitting down and grinding with a mortar and pestle was meditative, but tedious. The same thing happens with coding--there are parts that are exciting, but there's (at least to me) a certain tedium that comes with testing, engineering, etc (if I want to write code that other people use, instead of one-off pieces for my own use). Even on the analysis side, there are exciting bits where I try to see if I understand why a material has a given set of properties, but there's a certain tedium in writing portions of the analysis code--the question is whether or not the exciting bits outweigh the tedious ones...One of my students (undergrad) was a double major between physics and computer engineering and has decided that he wants to go on to do robotics in grad. school--physics wasn't fun for him--another one went on to grad. school in physics--you just have to see what you have fun with--not just with classes, but in the actual doing. If you decide to stick it out and pass prelims/first year courses and get your masters and are still not happy, then definitely get out--opportunity costs will outweigh your sunk costs ;> At your university, do the theorists give trial projects? In terms of just variety and fun, have you looked at any of Nigel Goldenfeld's work? http://guava.physics.uiuc.edu/ http://guava.physics.uiuc.edu/ If you do decide to leave (and it seems like that's the direction you're going), then I suggest that you get an offer somewhere, spend some time working on your own project, or taking some CS courses before leaving... Good luck!

    > there's a certain amount of tedium in any endeavor. Yes, I'm cherry picking a bit here :) I think I was a bit too hard on physics in my previous comment. I've definitely loved it before, and I still do occasionally. I think the frustration I feel is partly due to school's tendency to suck the fun out of any subject (computers, too--I never really liked any of the programming/algorithms classes I took, but I enjoy learning a new language or algorithm on my own time). And once I'm done with my problem sets and things, I can't think of my physics books as being "leisure" reading (like I do with programming books). It would be just my luck, if I switch careers, to fall out of love with computers and end up courting Jackson on the sly! I think I'm most dissatisfied, right now, with the school/city/people. There's nothing interesting within a 6 hour drive, and I haven't made any friends--I've met a lot of people, so it's not for a huge lack of trying, but I don't really like any of them as much as I liked my friends in undergrad. I've thought about switching schools, but with all the hassle of re-applying and somehow explaining "I don't like anything about this place--would you write me a letter of recommendation?" coupled with my other reservations, I feel more inclined toward a career switch. It sounds like we have, at least, narrowed it down to a decision of personal preference. Which puts a lot of pressure on me! But still, progress. Thanks again!
