The heck is a modular form?

For a work assignment, I need to come by a conceptual understanding of modular forms that's light on jargon and, ahem, actual math. If such a thing is possible.

Teach myself Math virtually for the first time.

I'm a 21 year old college senior liberal arts major who has managed to slide by in school (and life) without ever really learning math beyond a middle school/very early high school level. For no reason in particular, I've decided that I want to get serious about bettering myself in the math department. How can I teach myself the academic math skills I missed out on? [more inside]

Online Math Tutor

I'm a college student who is having some issues really understanding Calculus II, which is a problem as A) I am a Comp Sci major, and B) I need to take Calc III as well, and an advanced math elective as well. I've not heard good things about the school provided tutors, (IE, one is not too skilled at math, and the other is really smug and poor pedagogically) and while I could get a private tutor to help me, I was wondering if there are any good resources for online math tutors, like there are for online language tutoring over Skype. Does a directory of such tutors exist, has anyone had a good experience doing this (maybe even with names?), and how much can I expect to pay? [more inside]

Perspective drawing calculation

If I want to draw something in one-point perspective, say, like a set of railroad tracks where the vanishing point is on the horizon, and the tracks are represented on the picture plane by an equilateral triangle (they appear that way to the viewer), the apex of the triangle being the vanishing point on the horizon and the base of the triangle is where the tracks meet the picture plane, how do I calculate where the railroad ties would be? (Given that in 3D they are evenly spaced. Also, I'm not really concerned with the thickness of the ties -- we can consider the ties to simply be horizontal lines.) [more inside]

What is the point at this!

Here’s a simple computational geometry problem. I am trying to figure out the value at an point of two line segments based off of the values at both of one of the segment’s endpoints. The problem is that I don’t exactly know the best way of going about finding the value at one of those points. Here is a reference figure. Given values (X_C, YC) = F_C (X_D, YD) = F_D How can I calculate the value of F_E, where F_E = (X_E, Y_E), where E is the point on the segment CD, where CD intersects with the line AB?

How to solve a complex statistics problem with a script?

In this game, you roll a number of six-sided dice to get a total. The total is either the highest single die result, or the sum of any multiples rolled, whichever is higher. For example: If I roll three dice and get a 3, 4, and 6, my total is 6. But if I roll a 4, 4, and 6, my total is 8, the sum of the two 4s. What I want to find out is the mean, median, mode, and standard deviation of the possible totals given N dice. How might I create a simple script to compute this? [more inside]

GRE-Filter: I was happy with my GRE scores. Then, I received word that I have the opportunity to get into a super-duper-top-tier doctoral program previously inaccessible. However, my Quantitative Score--while still in the range of accepted scores over the years for this program--is now less-than-stellar relatively speaking.

what sort of maths do the aliens have?

Are some areas of maths inherently central and others as more peripheral? Or is any sense of centrality just a human experience, a cultural artifact arising from: what has had greater application, what has been studied more, what produces a greater sense of the sublime in the human mind? Are some parts of mathematics inherently a more fundamental description of what is going on in the universe, or is it as silly (or correct?) to talk about maths that way as it would be to talk that way about a classical ballet?
