Movie: Square peg and round hole

I like to show movie clips when possible so that my students can see the drama of an engineer's world. Apollo 13 is a no-brainer; engineers are everywhere -- and it's one of the few American films where they are the heroes.

This particular scene is one I use to dispel the half-conception that "engineering and science are the same". It illustrates the fact that engineers work within constraints.
