How to Make a Tetrahegi Line Up Using a Computer Simulator

There's all these forces, and i have no idea which ones are more important than than others. I don't know which one is contributing to this assembled structure versus that assembled structure. So at some point i told the student, ok, just turn them all off. Turn off all the forces. It's too complicated. And we'll turn each one on one at a time, and then we'll learn what is the role of each force independent of all the other forces. That's the beauty about being a computer simulator, is that you can do these things that experimentalists can't do. We can onern all the forces in our simulation.
