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. I hope you can see through this and help me. I will be using the words matrix, mean and transformation without fully understanding them. For this I apologize. [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.

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

My cousin's four year old son is obsessed with things like quarks and infinity. He insists to his mother that infinity is the last number. She isn't so sure, and wants to know more about things like strangeness.
I don't want to determine this kid's future, but it seems fun to feed his curiosity. And since my wife's babysitter was Murray Gell-Mann, the responsibility has fallen partially on my shoulders to help answer his questions. What kinds of information can you recommend that I give to his mother so that she, an attorney and not a mathematician, and her son can learn more about this information. In particular, what kinds of books, games, and projects would introduce him to other neat ideas in mathematics and physics?
