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?

But Sir, what is x? Teaching students algebra for the first time. They keep wanting to put values in for x, and write that down. E.g. x + x = . Becomes 1 + 1 = 2, in their books. Whereas I want x + x = 2x. Does anyone have any strategies, or techniques to overcome this? [more inside]
I've been seriously considering becoming a high school math teacher. I have some experience teaching in a classroom, and lots of experience tutoring. What I'd like to know now - before I jump into an alternative degree program - is what it's actually like being a teacher day in and day out. If I'm not going to be able to hack it, I'd rather know now. [more inside]

Assuming a grasp of college algebra, what maths would one need to understand the entirety of the wikipedia entry on white noise. Which order would be the most advisable way to learn those maths and which books might be good for a self study on those topics?
I'm writing a graphics app where I'm generating a simple gear transmission system with a variable number of gears each with variable number of teeth and placed at random orbits around each other. I generate gears in succession, placing and rotating each with respect to its parent/driver gear before moving on to the next. The problem I'm having is how to determine the initial orientation of each subsequent gear such that its teeth are properly meshed with that of its driver. [more inside]

I need help understanding the "principle domain" (a term only my professor seems to use) of a polar function. That is, how do I find the smallest value delta such that [0,delta] plots all of the unique points on the curve; any values greater than delta re-trace points. I suspect that if MeFi could identify the more common name for this, uh, procedure, I'd be set.

I have 232 facebook friends, and six of them share a birthday in common (not 6 different pairs of people on the same birthday, but 6 out of the 232 were born on the 17th of July. Now, I know it only takes 23 random people to get a 50% chance of at least ONE birthday collision, but how the heck do I figure out the odds on this one? Is this a significant anomaly, or reasonably expected? My one stats class was entirely too long ago....

I am a teacher at a high school that will be providing netbooks to every single student this fall. I am trying to consider ways that this will be helpful in the classroom, particularly in a math classroom. If you knew that every child in the classroom had their own netbook and the classroom were wireless, what would you like to see happen that would help students learn math? Please fire away ideas. All are welcome - whether brainstorm ideas or maybe you know of a particular website or web-based tool that would help students. Particularly, I'd like to assess students' progress as they learn as well as to provide them multiple ways to learn/experience the fundamental concepts in a math course. What would YOU have wanted if you had a laptop and wireless in high school? Thanks for your suggestions!!!
