From a girl...if you care (Score 1)

Check out university course web pages from good schools. I specialized in astrophysics but don't work in it but I like to stay on top. I check out class syllabuses for to date and new reading. There are so many books out that I like to see what has recieved the stamp of approval for professors at respected universities. Find a subject that really interests you and the math will always be there. Personally, black hole are always fun, you get a little of everything from them.
