I'm a pure mathematician with a Ph.D. and I'm currently a visiting professor at a large state university. However, I'm looking to switch gears and get into the quantitative finance field. The problem is that I don't know anything at all about finance. I know that there are companies such as D. E. Shaw that hire mathematicians that don't have financial experience; what other companies should I look at? Is there any general advice you'd give someone in my position? Also, I have my Ph.D. from a well-regarded state school, but I'm not an Ivy-leaguer; does that put me at a disadvantage?

Recently, someone described a 10-volume mathematics textbook series to me. The books were written by a single author, an engineer with a name that sounded Greek, and came with full worked solutions to every single problem, making them ideal for self study. Unfortunately, they could not remember its title, and my attempts to find it with Google and Amazon have failed.
Has anyone come across this series?

Can I get into a funded Math Master's or PhD program? I'm graduating from a 4-year college with my B.S. this Spring, and I'm in my mid-30's. I have good GPA at this school (about a 3.6, up to about a 3.8 in math courses specifically) and good GRE scores (720 V / 780 Q), but I have dropped a lot of courses (I've worked full time over the years while getting my degree), and back in the mid-90's I flunked out of the first university I went to.

How do you multiply probability across multiple chances? Let's say that every time you roll a die, you have a one-in-six chance of having five come up. What math would you perform to come up with the probability of five coming up at some point with the dice being rolled two times? Three? Five? Ten? (I'm using dice as a shorthand here: the actual probability figure I'm working with is 24%.)
