Homework Statement I am having problems solving this system of non-linear equations in Matlab and Mathematica. a,b,c,d,e,f are all independent variables. In Matlab I use fsolve() and get one solution, in Mathematica I use NSolve[] and get another totally different solution. Mathematica...

Here's a sketch of my crude calculations: As we all know the potential energy stored in the electric field of a system of two electrons is U = \frac{k_c e^2}{r} where kc is the constant in Coulomb's law, e is the charge of an electron and r is the distance between the electrons. With...

One of the biggest problems with launching things into space is that fuel weighs a lot. With conventional rocketry, mass of fuel per unit of stored energy is high enough that it requires huge rockets to lift even a couple of tons into orbit. Electrons are very light, and can be used to store...

I understand this. Does this mean that if you take any two bodies traveling along distinct paths through the universe, at any point that they meet, you can tell which one has undergone the most acceleration by finding out which one has 'aged' the least?

Can someone explain why it isn't so that Gracie experiences 6 years and George experiences 60 years? If you take George's frame of reference to be static, isn't Gracie then the one who should come back in George's future?
