I have just completed my MSc in mathematics in Europe. I do enjoy math, but I spent my uni years feeling like a autodidact hippie marooned on an island full of Mr and Mrs I-Want-A-Good-Job. My main interests revolve around humanities (literature/history/anthropology) and economics (but not finance), and instead of starting a "stable" well-paying career I dream about something inter-disciplinary. I am very open to earning little money and relocating just to do kind of work that engages those skills. What are some random uses of my degree? [more inside]

Why do we have order of operations rules in arithmetic instead of just strictly evaluating expressions from left to right (possibly with parenthesis for grouping if we really wanted to change the order)?

My son is 10 years old and going into 5th grade in the fall (but he usually does 6th grade math). He likes Stack the States, and we're looking for a math app with similar appeal. We already have Sushi Monster and his younger sister loves it, but I'd like something more challenging for him.

Help me with statistics and Excel. Especially help me if you know any labor saving methods.

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?
