I'm a bit of a polling junkie, and in general, I'm pretty good at math, but I can't figure this one out (at least, not yet). As a concrete example, I'm going to use the latest Gallup survey: Obama: 49%. Romney: 44%. Margin of error (95% confidence) = 2%. As I've found out, the...

I wind up at the same spot.

Homework Statement 2) If a relativistic rocket has a proper acceleration alpha that increases with proper time tau according to: alpha(tau) = 2/[Cosine(tau)^2 - Sine(tau)^2] find its motion, r(t), from the point of view of a control tower for whom the rocket is motionless at...
