Is there a means of fitting curves to several independent series of points with the property that, if all the points at any given x in the original data have a constant sum, all of the interpolated points at any given x have a constant sum? Is there a means of doing so which generates a set of cubic or quadratic Bezier curves which I can use in SVG rather than a series of points or a function? [more inside]

I tutor several people in a "Mathematics for the Social Sciences" course at a local university. This semester the material is focused on matrix algebra. For the most part, they have no trouble wrapping their heads around the notions of basic vector operations, row reduction, systems of equations, inverse matrices and determinants. But, they have a lot of problems with more abstract concepts such as linear independence, subspaces, basis and dimension. I'm wondering if anyone has any tips on helping them visualize and understand these ideas more clearly.

What's the advantage of using radians instead of degrees? I've never had a satisfactory answer to this. In high school, we always used degrees to measure angles and starting in university we switch to radians. Is there really any benefit to using radians?

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?

My son asked me how many trees there are in the world. I know there are a finite number, yet I also know that it is not practical to count them. Same with grains of sand. When the set cannot be measured because it goes on forever we say the set is infinite. Is there a single word to express the concept of a countable, finite number too large to actually count?
