I know that its very hard to get tenure even if you get a phD in astrophysics from an Ivy league school. hence, a lot of astrophysics phDs find jobs in government labs, wall street, or as engineers. but how likely is it to find employment as a engineer where you get to work on CFD? My...

Hey guys! I'm sure this has been asked before, and I hope not so much as to warrant a "use search function!" but my time is somewhat limited. I'm starting university up again soon and I've been debating between psychology and astrophysics/astronomy. The problem is, my math is lacking -- just...

Hello everyone, First off, I wanted to note that this is a great forum. I've spent the past hour or so looking through different topics of varying nature and I've really enjoyed reading through the conversations. Anyway, I'm in a little bit of a bind regarding college. I'm going to be an...

Is it possible o get a PhD in both theoretical physics and theoretical astrophysics at the same time, or is it too much to handle? Also, would it better my chances of being hired for NASA as an astrophysics and a math PHD rather than a theoretical physics and astrophysics PHD, or does it not...

I wanted to know if it would be at all possible to get my bachelor's degree in theoretical astrophysics at the time I'm 18. I'll be 16 when I graduate this year from high school, and I'm taking 2 dual credit college classes (the max a student can take). I'm also taking AP Physics and AP...

edit: I've decided to stick with CE. Though I do love the study of the universe, I don't think I would be able to hand graduate school and all the research that is packed along with it. The books I've read are enough to satisfy my interest in space and time. During this economy, I think I'm...
