    How much energy is needed to stop a crashing plane using a rocket?

    A serious problem in our use of planes for transportation is the possibility that they might crash. What if we could stop this? Here is the proposal, from a physics professor at my university. If at the time that a plane lost its ability to stay in the air a rocket was sent from the plane...

    Interesting problem from a Putnam student

    I'm taking the Putnam next fall, and decided to pick up a copy of Larson's problem solving book for practice. I'm having trouble, though, with one of the problems. It goes as follows. A well known theorem states that for a prime p>2, p=x^2+y^2 iff p is one more than a multiple of 4. Show...

    An interesting proposition Please read

    I've disagreed with my professor on this point, because I still cannot see how I am wrong. Consider the following equation: If x is an integer, (x^3 + x)/(x^4 - 1) = x/(x^2-1) I'm asked to either prove, or disprove this, and so I arrive at the following (man I wish I knew TEX or...
