Have him imagine that one day he will design an airplane or a giant skyscraper. What would happen if he makes an error in his calculations or assumptions?
I did this with DS9 yesterday, using a bridge as an example. The question was for him to imagine a bridge that might have to hold a thousand stopped cars weighing xxx kg if there was a traffic jam or some other problem on the far side of it.
Me: "What would happen if the engineer made a mistake in his calculations regarding how to make the bridge?"
<pause>
DS9: "It might collapse."
This example got him thinking.
