I'm co-developing an APCalculus course to be delivered by Distance Learning. As part of the introduction to calculus at the beginning, we're hoping to include a short video clip (say, five minutes?) of some heroic person (David Robinson, an astronaut?) talking about how calculus has changed his or her life (for the better, of course). Does anyone on this list know of any such clip? I'd be very grateful for any help and guidance you can offer.
