The trajectory of your shot is determined by the function you wrote, and your goal is to avoid the obstacles and your teammates and hit your enemies. The game takes place in a Cartesian Plane. http://grap...

### Re: Runge Kutta Domain Problem

For nonlinear DEs, this is very hard to do. If the DE is always the same and linear, you might be able to figure out the domain and put it in your program. It's not guaranteed to be linear and is not always the same equation =/ But by very hard to do do you mean it's impossible or really just hard ...

### Runge Kutta Domain Problem

The problem is that I need to know the domain of the solution, for example, the solution of the equation y' = -x/y is a circle, but the runge ...

### Re: Graphwar

Loading Java applet failed... I'm running Safari on a macbook, btw. I don't have acess to a macintosh... but I will see what I can do to solve this. Looking good. I tried to draw circles in (y') mode, but inputing x/y behaved oddly in the vicinity of y=0. Couldn't you just make it return an error, ...

Have you ever heard of seasteading? Seasteading is a project to let people live in the sea in floating platforms, and basically rule themselves.

### Re: Codify your system of morality.

My system of morality: 1. Do WHATEVER you must to assure the well being of yourself and close relatives (mostly of your sons and daughters). Of course you have to take long term effects into account, that means you're not going to kill your neighbor over some piece of cake. But in some bizarre circ...

Make a challenge that requires of them more than they know, so they will have to search for themselves the knowledge required to solve that (with teachers assistance available). 3. Make the groups compete with each other!...

### Re: A Philosophical Question That Has Bothered Me For Months

Assuming the existence of a God and a Devil

That's still extremely vague. There are so many views on God and the Devil that you can never reach a conclusion in this matter from this assumption alone, you would have to be much more especific.
