Does the fact that the betting markets still give Hillary Clinton a 1 in 55 chance of being President in 2008, mean that that is a reasonable estimate of the chance that Obama is assassinated before the election? What else could justify those odds now?
I'll graduate with a BS in mathematics in June. I plan on taking exactly one year off before entering a PhD program. What should I do during this time off, and what steps should I be taking now? [more inside]
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?
I heard about a book that covered philosophical questions at the core of mathematics. This interests me, but I'm really interested because if I remember correctly it used understanding of euler's identity as an example. What was this book?

I'd like to learn about SVM, HMM and wavelet algorithms in their usage in bioinformatics. I have a somewhat rudimentary understanding of the underlying mathematics from Wikipedia and a couple other sources, but I find that a concrete demonstration of their application fleshes it out. Are there texts, software packages (preferably free) or papers you'd recommend that: 1) includes good starter problem sets, or; 2) demonstrates how these techniques are used in research applications (beyond "we used xyz here"). Thanks!

Starting this fall, I plan on taking some preparatory undergrad coursework with the intention of eventually applying to a master's program in applied mathematics. I am seeking suggestions for reading material concerning the field of mathematics in general, both as a refresher and as insight into current focus areas and work being done. As a working engineer, my situation and background might be a bit different from most considering this route... [more inside]

3D Trig question: I have a 2D square in 3D space (a Face). I know the positions of the four corner vertices in form x,y,z. How do I calculate the rotation in degrees (Euler angles) as relative from the center of the face? I want to end up with degrees of rotations around x-axis,y-axis,z-axis. Bonus if you can write it in pseudocode.
Imagine a cube-shaped building, with ten cube-shaped rooms along each side (10 rooms long, 10 high & 10 deep). Each cubular room has 4 walls, 1 ceiling and 1 floor. Each of the 6 interior surfaces in all 1000 cubular rooms is decorated with a different piece of art. The rooms can be moved around the building, as if it were an enormous Rubik's cube, but they can also be spun on their axes, so all 6 walls of all 1000 cubes is capable of touching all the others (if the cube is so arranged). How many combinations of art within the 'Cube Gallery' are possible? If you can run me through the workings of the maths I would be extra grateful. Also, what technical words/phrases/language are useful/interesting in expressing this concept? [more inside]
I've charged with adding a feature to a shift scheduler / coverage requestor that displays shift information for a given week.

How many sides does a circle have? I always assumed the answer was an infinite number of sides. My boyfriend disagrees with me and thinks that the answer is zero. My brother seems to think that it depends on your definition of what a side is. I have searched all over but can't seem to find a definitive answer.

I remember reading an anecdote about Feynman, written by Feynman either in Surely, You're Joking or What Do You Care What Other People Think. He was describing how in his undergraduate years people were really impressed by his ability to do integrals, all because he knew this integration technique that wasn't taught very often. What was that technique?
