RRSP, CMHC, WTF

Starting a math minor. Any advice?

I'm half way through college and am about to begin taking courses for my math minor. However, the last time I took an invasive course on mathematics was during high school. I am looking for a couple textbooks/methods that will help me get up to Calc II proficiency by the end of this summer. Specifically, I need to tune up my Precalculus and Calc I skills. If anyone could recommend problem sets, online tools, and/or their favorite textbooks I would greatly appreciate it. I'd like to keep it under $100. Thanks. ~Stephen

Seeking advice/help about statistical tests of significance.

I have a wonderfully large dataset that I'm working with for a long-term project. I am analyzing a small section the dataset for my masters thesis. In meeting with my thesis advisor last week, she suggested I run some statistical tests of significance on the 4 tables I'm working with. She knows that I am yet to be versed in quantitative analysis methods (I've done solely qualitative work thus far) and that I'm under a massive time crunch to get this done. She suggested I seek help from others, as she doesn't want me to get bogged down with figuring out this step, and would rather I concentrate on analyzing the other aspects of this data. To this end, I'm wondering if somebody might be able to suggest the best type of test of significance to run, the easiest way to run it, and a good, simple resource for what the resultant values mean?

What books should I buy my math professors?

I recently applied to grad schools, and I got recommendations from three of my math professors. I'd like to get them all books as a "thank you" but I'm stumped on which specific titles to get two of them. The books don't have to be overtly math-related (thought it wouldn't hurt), but I think they probably shouldn't be completely orthogonal. If it helps, the book that I did buy is Michael Ruhlman's latest food book Ratio. [more inside]

Name this Mathematics Textbook series

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?
