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.

What is the most important scientific question of our time? [more inside]
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%.)
Is there a formula related to the statement "What's old becomes new again"? As middle age encroaches, it becomes harder and harder not to see history recycled and repackaged whether fashion, music, etc... [more inside]
Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

I want to calculate the mean of a matrix, but I don't want a value, I want co-ordinates. The following math question has lots of terminology that I'm not qualified to use i.e. most of it is wrong.

Math problem with shipping rates. Can a maths whiz point me in the right direction? [more inside]
I have always been horrible at math, but somehow a great programmer. I have found that writing a computer program that demonstrates a certain mathematical concept enables me to better understand the concept. I'm a psych major and I brought this up once in the research lab I've been working in. My prof said he recalls that someone did research and/or created a system in which a student writes a computer program that is pertinent to a certain mathematical concept and upon completion is given the regular math problem (as it would appear in a math class). This enables the student to better understand the math problem, solve, and learn math. Has anyone heard of this or anything similar? A learning system such as this would be a blessing to my education. Thanks.

On blank graph paper, what is the mathematically proper name for any random line you see on the page? It wouldn't be "coordinate" since that refers to the line's value. It wouldn't be "grid" since that refers to all of the visible lines. It wouldn't be "axis" since there can be only one in each direction. I'd also be cool with the name for all of the lines (as a set) that are parallel to one another. Thanks!

There is the story of the perennial house guest who is either a distinguished mathematician or a physicist. The story goes that if this gentleman comes to stay with a young scientist it means that their future in the field is in for a sudden uptick. His tenure in their home tends to result in a few collaborative papers which in turn leads to notice in the scientific community and a rapid rise in status. Please help me find this professor's name?

Here's the deal: I've exhausted my neurons looking for some kind of answer to a mathematical symbol stumper. I'd love to know who invented, originated, or was the first individual to use the double-tilde (≈) as a means of expressing/denoting "approximately equal" in mathematics. I know that Robert-Recorde is supposed to have introduced the "equals" sign (=) in 1557. Any and all assistance is greatly appreciated. I await enlightenment.

Sometime in the past two months, I came across a blog entry (I think) which asked for expressions for the "largest finite number" that could be submitted. Intuitively there is no such thing, but the piece toyed around with that idea. If I recall, there were few if any restrictions on the how the expression was written. Sorry I can't be more specific than that. I'm not interested in "all you have to do is add one" replies, only pointers to the site if the general parameters of the question are familiar to anyone
