I think his problem is very interesting

Let k>=2 be an integer and let p be a polynomial of degree >=2 with integer coefficients such that the coefficient of the leading term is positive. Prove that Sum (k=1, oo) 1/(k^p(n))converges to an irrational number.

Hey everyone! I've got a fun little project in Robotics 9 that I could use help with: design an amphibious Mousetrap-powered car. The Vehicle must go through regular land There are design restrictions as well, we can only use basic mousetrap car materials, plus some other materials like soda bottles, sinkers (the thing you put @ the end of a fishing line) etc. We aren't allowed any "creative additions" (like using substances to react with the water and create propulsion) We can either go through the water (float the car across by attaching the empty soda bottles) or under it (drive through the bottom)

All that being said: here are the q's:
1. Would going under the water or on it's surface be more efficent?
2. Any web links to a page for driving mousetrap cars (no boat pages) in water?
3. Any other suggestions at all? much appreciated. 10 points to the person who's answer helps me out the best. I'm lost here!
